Kansas NSF EPSCoR Announces Spring 2019 MAPS Research, Education and Innovation Awards

     The Kansas NSF EPSCoR RII Track-1 Award OIA-1656006 Microbiomes of Plant, Aquatic and Soil Systems across Kansas(MAPS) has awarded seven Research and Education Innovation (REI) Awards for the spring of 2019. REI Awards are specifically for small projects that will either allow for networking and planning or allow for the immediate pursuit of larger projects that are developing new transformational concepts. Faculty from the University of Kansas (KU), Kansas State University (KSU), Wichita State University (WSU), Fort Hayes State University (FHSU) and Washburn University (Washburn) are all encouraged to submit proposals. This funding is awarded to both research and education projects, given their close relationship, and selections are made in the same spirit as and share goals with NSF EAGER (Early Concept Grants for Exploratory Research) awards for high risk/high gain research ideas. This year, the MAPS REI selection committee chose seven REI proposals to fund. Project summaries and the broader impacts of the investigations provided by the investigators of the awarded projects are included below.

A Potential, Unappreciated Mechanism Governing Transformation of Soil Organic C into CO2 by the Soil Microbiome

Project Summary:
     Understanding how changing environmental conditions influence microbially‐mediated transformations of soil organic C to CO2 is critical for predicting atmospheric CO2 concentrations1. Microbial generation of CO2 occurs after the soil microbiome (bacteria and fungi) take up assimilable compounds often derived from larger soil organic matter (SOM) molecules. Microbes must allocate some assimilated C to CO2, providing a feedback to Earth’s climate. The breakdown of SOM molecules is catalyzed by enzymes exuded by the soil microbiome (exo‐enzymes) for that purpose. These processes are well‐studied. We propose to explore a potential, unappreciated mechanism driving the ability of exoenzymes to encounter SOM molecules for breakdown – soil pH and its variation due to climate change. If validated, this idea can transform current perceptions of the drivers of SOM persistence vs. loss as CO2.

Project Summary:
     This is a pilot study to develop collaborative partnerships aimed at constructing a multi-institution (likely multi-state) research proposal to explore the connection among aquatic microbiomes and riverine water quality. Initially, we will focus on watersheds within tribal lands in Kansas and Iowa with contrasting water quality impairments and water quality threats. Specifically, we intend to start networking with the Meskwaki Nation, tribes in the Kansas River watershed, and Kansas State University. Our vision for this initial phrase is confront current cause-and-effect models of the connections between aquatic microbiomes and water quality with available data. This process will highlight the gaps in our understanding, thus allowing us to focus our proposal on the most relevant questions and hypotheses. Concurrently, the MAPS component of the current Kansas EPSCoR grant has begun monitoring water quality and aquatic microbiomes in the Kansas River watershed. The opportunity to leverage the microbiome findings of the MAPS project sets the stage to potentially transform water quality monitoring programs into a more holistic chemical and ecological science.

Project Summary:
     Our ability to predict how aquatic microbiomes will respond to projected scenarios of environmental change is dependent on being able to accurately model the dynamic coupling of groundwater and surface water and the subsequent effects on the chemical, physical and biological in-stream environment (Sullivan et al., 2018a). While a variety of surface and subsurface water quality models exist, these have not yet been adequately linked due to system complexity and computational requirements (e.g., Cho et al., 2016; Oliver et al., 2016; Bao et al., 2017). This REI project seeks to create a transformative approach to groundwater-surface water modeling by forming a team of experts to generate a modeling framework and develop a collaborative multi-disciplinary, multi-institutional proposal for submission to NSF.

Project Summary:
     Understanding river nitrogen (N) removal is of fundamental importance to ecosystem science given the critical role rivers play in mediating nutrient delivery to coastal waters.1-3 Downstream export of N to larger rivers is controlled by the relationship between N supply and demand.4,5 Stream N supply is influenced by hydrology (e.g., the precipitation gradient in KS) and land use.3,6 In-stream demand for N is determined by the stream microbiome – the microbial community that processes N via assimilation (uptake of N for biological growth) and denitrification (an energy-generating process used by some bacteria which converts nitrate to gaseous N2).7-10 Studies of stream N processing often focus on either the supply of N to streams or the demand for N within the stream, but rarely combine measurements of whole stream N processing rates with detailed analysis of the stream microbiome. Furthermore, it is even more rare to link stream N-process rates and microbiome composition to stream metabolism, the integrated rate of all energy producing and demanding biotic activities within a system.11 Integrating coupled energy nutrient cycling with an understanding of changes to the stream microbiome represents an important research frontier for understanding how streams control nutrient inputs to costal ecosystems.11 This research explores the connections between stream microbiomes, N processing rates, and stream metabolism. We ask: How does stream intermittency (represented by the precipitation gradient across KS) and land use affect the N supply vs. microbiome demand for N? We will address this question using a combination of new data and experiments, as detailed below, together with data currently being collected by the KS-ESPCOR Microbiomes of Aquatic, Plant and Soil systems (MAPS) project. MAPS activities currently include measuring stream metabolism and stream microbiome characterization, but do not measure in stream N processing. We seek to supplement this strong foundation by: 1) deploying a nitrate sensor (from Burgin’s lab) to pair with the MAPS-funded metabolism sensors to measure coupled energy-nutrient cycling, 2) conducting whole-stream N uptake and denitrification experiments to quantify microbiome-driven in-stream processes, and 3) relating the microbiome process measurements to the characterization of microbiome community composition. We will perform this work at the 12 MAPS core streams that will span a range of land use and precipitation (thus, a range of N supply to the microbiome). Including measurements of N demand via in situ microbiome activity will provide a critical link between the composition and integrated functionality stream microbiomes. Beyond establishing this empirical link, our larger goal is to share this cutting-edge data at a symposium with stream researchers in neighboring states and generate regional engagement on an NSF Macrosystems proposal (solicitation 19-538).

Increasing Aquatic Ecology Expertise in Kansas

Dr. Greg Housman
Dr. Greg R. Houseman
Biology & Field Station Director Biological Sciences
Wichita State University 

Project Summary: 
     The purpose of the proposed initiative is to facilitate a new faculty hire with expertise in aquatic ecology at Wichita State University.  Wichita State is a Kansas Regents Research University that has shown remarkable increases in research capability over the past few years.  For example, funded research has increased from 50 to 100 million dollars per year over the past decade.  A similar trend is evident within the Department of Biological Sciences that currently has 11 awards totaling nearly 9 million dollars across the twelve research faculty.  Likewise, the WSU Field Station has experienced a rapid increase in capacity with two externally funded projects (NSF, USDA), an increase sites from 489 to over 5100 acres, and investment of over 1.1 million dollars in facilities and equipment over the past decade.  Several of the Field Station sites include important aquatic resources (springs, streams, rivers, and impoundments) in the southern part of Kansas.  However, the Department of Biological Sciences has no faculty with sufficient expertise to study aquatic systems or contribute to the broader examination of aquatic resources in Kansas.  Consequently, WSU would like to create a new faculty line to address aquatic ecology (broadly defined) to increase the momentum of the Field Station and within the Biology Department.  This objective fits well with the innovative goal of the MAPS project to link plant, soil, and aquatic microbiomes.  Specifically the new aquatic ecologist would address the MAPS thrust of aquatic systems and contribute to Goal 1.1. of the MAPS project:
“Characterize the structure and biogeochemical processes of the aquatic (stream and reservoir) microbiome resulting from variation in hydrologic connectivity, nutrient loading, and land use across the Kansas precipitation gradient” The focus of the aquatic ecologist will likely focus on understanding aquatic systems in Kansas and fostering linkages across plant, soil, and microbial dimensions.  It is expected that this new position would begin in August of 2019.

Expanded Kansas Ecosystems for Elementary Students

Project Summary:
     The Kansas Ecosystems for Elementary Students program (KEES) began a year ago, funded by EPSCoR MAPS, with the goal of developing hands on experimentally driven activities focused on Kansas ecosystems that support Next Generation Science Standards (NGSS) for elementary grades. We are currently visiting 13 third grade classrooms in Lawrence and Topeka. We will be visiting each classroom 5 times through this academic year. Our program was quite popular in its first year, and we were invited to return this year. Rosemary Blum interviewed one of the teachers whose class has been participating in the program this year and she said “I love that the program is engaging for students. It brings in resources that we do not have access to as a public school, and opens the eyes of our students to things they normally would not be able to experience.” We believe that by engaging students in this way we are enhancing students’ interest in science and facilitating students understanding of concepts that will support their academic success.  To expand the program, additional funding is needed for infrastructure to support planning of programs, organization and coordination of visits with teachers and instructors from KU and K-State, and hiring and training of more facilitators to serve as travelling prairie ambassadors to multiple schools. Given the importance of students developing an appreciation and understanding of science early in their academic life we would like to expand the program to reach more classrooms in Lawrence and Topeka.
     The first lesson of the year focused on the Prairie Biome, where students learned about the characteristics of the prairie ecosystem and were able to see bird and mammal skins from the Kansas grassland and dissect Barred Owl pellets. The second lesson focused on why and how plants disperse their seeds. Students saw how native plants disperse their seeds by wind, water, gravity, explosions and using animals, they then were able to design, build and test their own seed dispersers. We will be continuing to work with the students this spring. We will be demonstrating how energy moves through ecosystems, dissecting soils and testing the rate that water travels through different kinds of soils. We will also be illustrating the services that ecosystems provide us, for example students will be observing and testing models of how water flows with gravity to form rivers, streams and how damming waterways provide stable water supplies. We plan to develop more lesson that can be taken to classrooms as stand-alone or be combined with the lessons we have already developed.

Project Summary:
     The objective of this research is to identify novel microbes and enzymes that biodegrade perfluorooctane carboxylic acid (PFOA) and perfluorooctane sulfonate (PFOS). Bioremediation technologies could significantly reduce the costs of remediating per- and polyfluoroalkyl substances (PFAS) contaminated sites, but only a few microorganisms and enzymes have been studied and shown to transform these compounds. In order to advance biodegradation options, the proposed research will combine metagenomic methods with thermal proteome profiling (TPP) methods to develop a broader understanding of the biodegradation potential for PFAS. The soil and groundwater at Fort Leavenworth, Kansas (FLK) has been exposed to high concentrations of PFAS for long periods of time due to firefighter training activities and operation of the airfield by the US Army. The Environmental Protection Agency has issued a health advisory for PFAS contamination in drinking water, and FLK has contracted alternative drinking water supplies at a cost of > $1 million annually. This site offers a unique opportunity to assess the impact of PFAS on the aquifer microbiome as a significant PFAS concentration gradient exists in the contaminated groundwater. However, PFAS contamination is widespread in the United States, and the United States House of Representatives launched a bipartisan taskforce for PFAS management on January 30, 2019.

MAPS Graduate Student teaches "Sunflower Science" to school aged children

Ashlee teaching Sunflower Science at the Kansas Children's Discovery Center
 and how to build a microbiome to 4th graders
     Outreach has always been a passion for Ashlee Herken, a  MAPS graduate student working with Dr. Tom Platt, Assistant Professor of Biology at Kansas State University (KSU) and team leader of the plant systems research group for the Kansas NSF EPSCoR RII Track-1 Award OIA-1656006 titled: Microbiomes of Aquatic, Plant, and Soil Systems across Kansas (MAPS). Part of the reason Ashlee chose to do outreach was because she was "extremely interested in representing women in science, promoting the research at Kansas State University, and supporting science education," plus, she loves "interacting with the children, because they are always extremely eager to learn about science.” In fact, it was her own fond memories of participating in science activities as a child that encouraged her to go into the field of science. Participating in the those interactive activities also contributed to her desire to lead outreach activities; and through her outreach, Ashlee hopes to not only serve as a role model, but also show "kids that science is interesting and that as long as they have a passion they can do whatever they want to do in life!"
     In order to pursue her passion, Ashlee chose to partner with Ms. Caitlin Luttjohann, the director of STEAM education, at the Kansas Children’s Discovery Center in Topeka, KS because “it is a wonderful resource for the children in the area where I live.” In addition to teaching at the Discovery Center, Ashlee also reached out to Mrs. Gretchen Giffin, a teacher at North Fairview Elementary School in Topeka, KS, and has provided interactive science activities for her fourth grade class. The outreach lesson Ashlee teaches involves children building sunflower microbiomes, and this Sunflower Science lesson was derived from her own Master's program research.
Sunflower Science Lesson
      The title of Ashlee’s thesis is Identification and characterization of cooperators and cheaters from natural populations of Agrobacterium tumefaciens at different spatial scales across Kansas, and her research focuses on “isolation and characterization of Agrobacterium tumefaciens, an important member of the root system community of Helianthus annuus, better known as the annual sunflower, across the state of Kansas.” She explained her research as follows: “Agrobacterium tumefaciens is a generalist plant pathogen that is the causative agent of crown gall disease. Within the population of Agrobacterium tumefaciens there are organisms that have the ability to infect the plant and those that just use the nutrients the plant produces for the bacterium these are essentially free-loaders, we call them cheaters. I am particularly interested in the evolution of the cheaters as well as the interactions between different natural isolates and a known pathogenic strain.” She added that the interactive lesson she created is very similar to the activities she does in the lab. Ashlee explained the similarities as follows, “When I go to into the classroom or to the Discovery Center, I have a presentation titled Sunflower Science and the kids build their own sunflower microbiome. At the Discovery Center, they use stickers of different colors and put them on a model sunflower. In the classroom, they used model sunflowers and glue beads to it. The stickers or beads represent the bacteria. I talk about the positive and negative interactions in the rhizosphere and the reasons that bacteria like to live there. I also talk to them about the bacteria that I am interested in and the interactions that it has with other members of the same species and with the plant.”
    Ashlee graduated last May with a Bachelor's of Science degree in Molecular Biology and Biotechnology from Washburn University in Topeka, KS. While pursuing her undergraduate degree, Ashlee worked on several research projects. One of her main projects was “working on the characterization of a Bacillus subtilis phage that was isolated from a farm in SE Kansas.” In addition, Ashlee was involved in a collaborative project between Washburn University and Washington University in St. Louis called The Genomics Education Partnership. It was during this project that she learned to “annotate a portion of the Drosophila eugracilis genome using Drosophila melanogaster as a reference.” During her final semester at Washburn, she had an internship with Dr. Bret Freudenthal's Lab working with one of his graduate students, Matt Schaich, and they tried "to elucidate the structure of the telomerase protein, which could potentially be used in the future as a target for cancer drugs.”
     Ashlee is originally from Oskaloosa, KS, but is currently living in Topeka.  As for her future plans, Ashlee said “I would love to continue doing research after I graduate. Currently, I am looking into different options. When I started graduate school, I was not aware of the wide range of careers that would be available to me after graduation. Ideally, I would love to continue to work with plant associated bacteria and the microbiome.”

Funding for Workforce Development, Education and Outreach in support of graduate students is provided by the Kansas NSF EPSCoR RII Track-1 Award OIA-1656006 titled: Microbiomes of Aquatic, Plant, and Soil Systems across Kansas. The grant's workforce development and educational objectives are designed to enhance STEM education in Kansas by supporting activities that will lead to an expanded STEM workforce or prepare a new generation for STEM careers in the areas of aquatic, plant and soil microbiome environments and ecological systems.

HERS student explores "Fire Sovereignty: Using Prescribed Burns to Conserve Tallgrass Prairies on Tribal Lands"

Kynser Wahwahsuck presenting
her research at the 2018 UCAR conference
   Kynser Wahwahsuck participated in the 2018 Haskell Environmental Research Studies (HERS) Summer Program after she received her BS in Environmental Science from Haskell Indian Nations University in Lawrence, KS. https://www.haskell.edu/sponsored-programs/hers/ The HERS program is one of the educational outreach initiatives proposed in the Kansas NSF EPSCoR RII Track-1 Award OIA-1656006 titled: Microbiomes of Aquatic, Plant, and Soil Systems across Kansas (MAPS). The HERS program provides a platform for various stages of student support as they research topics that are of particular interest to American Indian/Alaska native communities. The program allows students to conduct independent research and present their findings at a national convention. HERS students from past years have focused their research on exploring “the effects of climate change on indigenous communities; the interconnectedness between wetlands resources, specifically soils, vegetation and water and the disruption to those ecosystems; and the significance of sustainable gardening practices.”  
    Being a member of the Kickapoo Tribe in Kansas, Kynser was interested in studying the effectiveness of the Kickapoo Tribe’s “mitigation of invasive woody species on tallgrass prairie utilizing indigenous burning practices.” She titled her project Fire Sovereignty: Using Prescribed Burns to Conserve Tallgrass Prairies on Tribal Lands and she explained her research as follows: “Before colonization, Indigenous people used fire as a method to burn grasslands to clear large areas of land in order to lure game for hunting. In addition, fire management was crucial in maintaining a healthy ecosystem for tallgrass prairies that became overgrown with invasive woody species. With changes in climate in the Midwest, these woody species are more abundant today due to the increasing warm weather and decreasing precipitation. In this research, I wanted to know how Tribal lands were managing their tallgrass prairies. I visited the Kansas Kickapoo Tribe Environmental Office and they showed me their practices for conserving the prairies on the reservation. I discovered how little of the prairie is left and how fire is managed differently now in present time. Based on my findings, I concluded the use of prescribed burns should be conducted once a year on the Kickapoo Reservation to suppress the woody material encroaching on the abandoned hay field and to restore the native prairie.” This past summer, Kynser presented her research during a poster session at the University Corporation ofAtmospheric Research (UCAR) 2018 Conference held in Boulder, CO.   
     Part of the HERS program involved visiting MAPS researchers' labs and that was when Kynser met Dr. Amy Burgin, co-team leader for the Aquatic MAPS research, Associate Professor of Ecology and Evolutionary Biology (EEB) at the University of Kansas (KU), and Associate Scientist for the Kansas Biological Survey (KBS). Once Kynser began working with Dr. Burgin, her research interests changed to aquatic ecology, and this is how she enthusiastically described what she is now doing with this new research focus, “I have gotten dirty helping with water sampling at Milford Lake! Currently, I am measuring phosphorus concentrations in Milford Lake where Cyanobacteria reoccurs.” 
     As for her next steps, Kynser said, “I will be starting my Master’s with Dr. Amy Burgin this summer and will be measuring stream nitrogen cycling processes across Kansas in the EPSCOR MAPS project.” In addition, and because of the HERS experience as well as the encouragement and support of Dr. Burgin, Kynser wants to mentor future indigenous undergraduate students.

Kynser is from the Kickapoo Tribe of Kansas located in Brown County. While attending Haskell Indian Nations University in Lawrence, KS, she was a member of the Student Ambassadors, the Haskell Tribal Eco-Ambassadors, Gamma Delta Pi Sorority, and served as a Student Senate Representative and Treasurer as a freshman. This summer, she will attend the University of Kansas and pursue a Master’s degree in Ecology and Evolutionary Biology with Dr. Amy Burgin.

Workforce Development, Education and Outreach funding for the HERS program is provided by the Kansas NSF EPSCoR RII Track-1 Award OIA-1656006 titled: Microbiomes of Aquatic, Plant, and Soil Systems across Kansas. The award's workforce development and educational objectives are designed to enhance STEM education in Kansas by supporting activities that will lead to an expanded STEM workforce or prepare a new generation for STEM careers in the areas of aquatic, plant and soil microbiome environments and ecological systems.

MAPS Professor publishes 3rd edition of textbook titled: Freshwater Ecology

     Walter Dodds, University Distinguished Professor of Biology at Kansas State University (KSU) and Co-PI of  the Kansas NSF EPSCoR RII Track-1 Award OIA-1656006 titled: Microbiomes of Aquatic, Plant, and Soil Systems across Kansas with his co-author Matt Whiles, Professor and Chair of the Soil and Water Sciences department at the University of Florida, have published their third edition of their texbook titled Freshwater Ecology: Concepts and Environmental Applications of Limnology. Everything from basic chemical and physical properties of water, to concepts of community ecology are discussed in the book. Ecosystem relationships found in continental waters and recent topics that influence aquatic environments are also addressed.  In additon, the authors explore details related to key issues such as how to balance ecological and human health needs, GMOs, molecular tools, and fracking.

The book will be available starting April 26.

The 2018 Ecosystems of Kansas Summer Institute leads to a continued partnership with MAPS faculty and a collaborative research project for high school students and teachers across Kansas

Pam Lucas
Science Teacher
Skyline Schools
     Last summer, Pam Lucas attended the 2018 MAPS Ecosystems of Kansas Summer Institute. The summer institute is part of the Kansas NSF EPSCoR RII Track-1 Award OIA-1656006 Microbiomes of Aquatic, Plant, and Soil Systems across Kansas (MAPS) education and outreach initiatives and is under the direction of Dr. Peggy Schultz, Associate Specialist, Environmental Studies Program at the Kansas Biological Survey. During the 2018 MAPS Ecosystems of Kansas Summer Institute, teachers participated in whole group field activities and small group curriculum development exercises in the areas of aquatic, plant, soil and geographical information systems. The activities were designed to mirror the Next Generation Science Standards (NGSS) Science and Engineering Practices.
     Pam’s curricular interest during the institute focused on developing activities related to the MAPS terrestrial (plant) systems research; however, she could easily see how many of the institute's activities could be taught to all her science classes. One of the first whole group activities was called Asking Good Questions. This exercise was led by Dr. Helen Alexander, Professor of Ecology and Evolutionary Biology (EEB) and part of the MAPS Plant Systems research team at the University of Kansas (KU)Pam saw this exercise as a student-centered approach to doing science, a key factor in designing project based lessons, so she incorporated it into her lesson plans. She started all of her science classes this year with this activity. Pam said she decided to teach the Asking Good Questions exercise, because it was a good way to teach her students how “to ask good questions and to realize the importance of doing so in science. Plus, this activity encourages a skill that applies to all of the NGSS standards and practices....” In addition, she said “I used the Pepper Population Simulation activity that Michael Ralph, Master Teacher from the KU UKan Teach program, shared with us to help my students model logistic and exponential population growth and to understand the differences between them;" As for the other activities presented, she said "I'm using the majority of what I have learned from the summer institute in my advanced class.”
    One of the projects that the teachers developed at the workshop involved collaborating with fellow participants from across the state. Pam explained their project as follows: I am working “with a group of teachers to design a cooperative project for our students to do utilizing little blue stem seeds collected from each of our home areas, plus, some from Indiana, Missouri, and Minnesota. We will be looking for variation of growth in little blue stem plants that have been inoculated with arbuscular mycorrhizal fungi (AMF). We suspect that the seed from south central Kansas will do better than that from the other states. At this point, my students helped collect blue stem seeds and those seeds were then planted and stored on campus, at KU. Later in the spring, some of the MAPS Ecosystems of Kansas Summer Institute terrestrial faculty will deliver the plants to us and help us plant them. We will take some initial measurements on a group of plants that we will plant in a plot at our school. There also will be some blue stems that we don't plant. With the plants we do not plant, we will do a small study to see how well AMF vs non-AMF inoculated plants grow by comparing plant size and root size.” With this lesson, she hopes to show students “the benefit of evolving symbiotic relationships, showing that natural selection leads to adaptation, and also show that those organisms with a heritable, advantageous trait will increase in proportion.” Pam admitted she is still developing some objectives for this lesson as well as for future lessons related to this experiment. She knows that all of the lessons she develops from this project "will fit nicely with the NGSS HS-LS4 standards dealing with evolution." This project will also incorporate teaching students many of the skills outlined in the NGSS Science and Engineering Practices such as collecting and analyzing data. Pam plans to use this collaborative lesson to serve as a foundation for several other project based learning lessons she plans to develop.
Pam with some of her students
     When asked what was the impact on students who experienced the MAPS Ecosystems of Kansas Summer Institute lessons, she said “Overall, I think that the lessons I have used so far have been beneficial to my students. They have learned the concepts and are better at applying them, which will help them do well on assessments.” And she was quick to add, “The kids that have participated in these lessons, so far, have done well connecting what they have learned to past lessons. I think that once our little blue stem study gets underway, I will see more of these connections being made. I'm excited to see this happen!”
     As for her thoughts about what she has gained from her participation in the MAPS Ecosystems of Kansas Summer Institute, she said “attending the Ecosystems of Kansas Summer Institute has really helped me get a start at becoming more project based in my classes. My school is one that is currently in the re-design process and doing more project based learning is part of that re-design. I feel that the summer institute has given me a good foundation to build on for this new approach.” Over this academic school year, Pam has maintained contact Drs. Helen Alexander, Peggy Schultz, and Jim Bever, Distinguished Foundation Professor in EEB at KU, Senior Scientist at the Kansas Biological Survey, and Co-PI for the MAPS project, “because we have had to plan quite a bit for our blue stem project. We actually had a zoom meeting with them and the other three teachers to discuss how and when to get our project underway this spring.  I'm looking forward to them coming to work with my students and I this spring. They have been great to work with!” Just last week, the MAPS research team traveled to Medicine Lodge, Pratt, Goddard, and Hutchinson KS to help each teacher and their students get this collaborative project started.
  Pam Lucas teaches at Skyline Schools in Pratt, KS. Skyline Schools is a PreK-12 school all in one building, and Pam is the high school science teacher. Approximately 100 students attend the high school section of the school. This is Pam's third year teaching at Skyline Schools.

Other teachers who participated in the 2018 Ecosystems of Kansas Summer Institute and who are also involved in the collaborative blue stem project are Jake Bjostad, Medicine Lodge HS; Marylee Ramsay, Goddard HS; and T.J. Williams, Hutchinson HS.

Kansas NSF EPSCoR Announces First Awards for the Spring of 2019

     Kansas NSF EPSCoR helps Kansas build its research capacity and competitiveness in science and technology through the First Award program initiated through the current Kansas NSF
EPSCoR RII Track-1 Award OIA-1656006 titled: Microbiomes of Aquatic, Plant, and Soil Systems across Kansas (MAPS).  MAPS First Awards are intended to help early career faculty become competitive for funding from the research directorates at the National Science Foundation. The awards do this by encouraging early career faculty to submit proposals to the NSF or other federal funding agency as soon as possible after their first faculty appointment, and by accelerating the pace of their research as well as the quality of their subsequent proposals. First Awards are awarded to a single-investigators to support their research program at their institution. Any tenure track faculty member who: 1) is currently nontenured at the assistant professor rank at the University of Kansas, Kansas State University, Wichita State University, Emporia State University, Fort Hays State University, Pittsburg State University or Washburn University; 2) is within the first three years of his/her faculty appointment; 3) has not previously received a First Award or similar funding from another EPSCoR or EPSCoR-like (Centers of Biomedical Research Excellence, COBRE) program in Kansas; and 4) is not currently nor has previously been a lead Principal Investigator of a research grant funded by a federal agency. Individual investigators may submit a total project budget of up to $100,000 in direct costs to the MAPS First Award program.  Only projects with research in areas that are related to the current Kansas NSF EPSCoR focus of microbiomes as broadly construed to be in aquatic, plant and/or soil systems were considered.  The following individuals and their research projects were awarded MAPS First Awards in the Spring of 2019:

Trapping and assistedpairing (TAP) microfluidic chip meant to study plant cell-microbe interactions in a microenvironment at the single-cell level

     The research goal of this project is to design and validate a scaled-down version of the Trapping and Assisted Pairing (TAP) chip, a microuidics
tool for conducting plant cell-microbe interaction studies at the single-cell level meant to advance microbiome research. This goal stems from the big picture idea of smart and sustainable agricultural practices to meet
the future global crop production demands in the era of ecosystem degradation and climate change. The TAP will be capable of screening up to 10,000 cell-microbe pairs for symbiotic/parasitic relationships, help plant biologists devise approaches to maximize the symbiotic functions/minimize the parasitic functions, and engineer stress-tolerant plants. The TAP leverages droplet microuidics to efficiently trap 10,000 pairs of droplets |one set of droplets containing individual plant cells and another set of droplets containing individual microbes |and merge the droplet pairs, initiating 10,000 cell-microbe interactions. For maximizing the cell-microbe pairs, it is critical to understand the droplet trapping and merging physics. The project objective is to describe droplet trapping and merging physics in
the traps, and demonstrate the droplet trapping and merging capabilities of TAP. This project will significantly advance knowledge on two fronts. Biology: Advance the understanding of microbiomes. The TAP chip is a cell handling tool designed to advance microbiome research by enabling plant cell-microbe interaction studies at the single-cell level. By integrating a computer controlled x-y stage, automated data acquisition system, real-time image processing, and traditional imaging infrastructure, the TAP will be a live-cell reporter system that can track the progression in cell-microbe interactions for extended periods of time, and thus allow it to answer a wealth of microbiome questions: What genes in cells/microbes turn ON/OFF during interactions? Are there any yet-to-be-discovered cell microbe relationships? Engineering: A fundamental understanding of the influence of trap geometry and fluid properties on droplet trapping and merging. The TAP leverages droplet microuidics to pair individual plant cells and microbes in a droplet. It is very critical to understand droplet trapping and merging physics for maximizing the plant cell-microbe pairs. Through first principles-based parametric studies, design charts and guidelines necessary for the design of traps will be created.

Upscaling transient microbial activity and soil moisture dynamics

     Soil water and heat dynamics exert a strong control on soil respiration by modulating the rate of microbial activity, substrate availability, and the diffusion rate of carbon dioxide at the soil aggregate level. Thus, a first order up-scaling of soil respiration from the aggregate level to the
watershed level inevitably requires knowledge of the spatial structure of-, and cross-scale interactions between, soil moisture, soil temperature, and soil respiration. The goal of this study is to accurately quantify watershed scale soil respiration applying a simple up-scaling strategy based on the merger of chamber-based soil CO2 efflux observations with modeling predictions. We hypothesize that combining detailed information about the soil spatial variability of the catchment area with accurate soil respiration observations and a parsimonious model will result in more accurate estimates of soil respiration than the use of chamber observations or model predictions alone. A distinct feature of the proposed method is the integration of time-invariant landscape patterns with the soil moisture information from a cosmic-ray neutron detector capable of large-scale non-invasive soil moisture observations. This project will bridge the gap point-level (i.e. small survey chambers) measurements that leave large unmonitored areas between observations ecosystem-level soil respiration products such as those generated by eddy covariance flux towers. The proposed method will provide a framework for integrating ubiquitous soil respiration measurements and existing models of soil respiration to reconcile soil and tower fluxes and to better measure the exchanges of carbon dioxide of terrestrial ecosystems. Up-scaling methods that account for watershed soil spatial heterogeneity are essential to account for potential soil respiration “hot spots” and “hot moments”, better evaluate factors controlling the spatial variability of soil respiration, and assess the representativeness of eddy covariance tower measurements. This is particularly relevant in a global scenario characterized by the widespread deployment of micrometeorological tower sites that use eddy covariance methods (e.g. FLUXNET), the growing market of automated chamber systems, and new hectometer-level, non-invasive soil moisture sensing technologies.

Prevalence and co-occurrence of pathogenic and cheater agrobacteria on healthy and crown gall disease infected sunflowers

     Cheaters threaten the evolutionary persistence of cooperative traits. When cheaters and cooperative individuals co-occur, cheaters have an advantage because they benefit from the costly action of their competitors while themselves avoiding cooperative costs. The investigators will examine the prevalence and degree of co-occurrence of a cooperative pathogen and the avirulent cheaters that exploit it. The generalist pathogen Agrobacterium tumefaciens infects plant hosts at great cost to itself. Infected plants produce a public good resource that the pathogen and any present cheaters can catabolize. Our work has experimentally demonstrated that the cooperative pathogen is vulnerable to invasion by avirulent, cheating genotypes of agrobacteria that out compete the pathogen in disease environments. However, the degree to which there is opportunity for this to occur in nature is poorly understood. Accordingly, we propose to assess how common cheating genotypes are and the degree to which cooperative and cheater agrobacteria co-occur in natural environments. We will sample agrobacteria from Konza Prairie from the rhizosphere of Helianthus annuus plants. Characterization of the pathogenesis functions, opine catabolism functions, and phylogenetic relationships of this sample of natural agrobacteria strains as well as those from an experimental mesocosm will allow us to determine the degree and distribution of agrobacterial genetic diversity and evaluate the prevalence and diversity of cheater strains. The investigators will also measure the rate and spatial scale of cooperator and cheater dispersal in experimental mesocosms to access how dispersal influences cooperative benefits and the spread of cooperative pathogens and cheaters. The proposed research will provide insight into the ecological dynamics mediating the evolution of cooperation. This proposal bridges concepts and approaches from ecology, evolutionary biology, and genomics to examine how competition and dispersal influence the dynamics of microbial populations. The findings are also relevant to understanding how microbial dynamics influence the spread of a facultative pathogen in both environmental reservoir and infected host environments. These issues are of key importance to understanding the epidemiology of pathogens that can live independent of their hosts. The plant pathogen A. tumefaciens has been a productive study system for determining the mechanisms of microbial interactions but the ecological consequences of these mechanisms are poorly characterized. The investigators have previously leveraged this mechanistic information to identify factors shaping key ecological and evolutionary processes like the fitness costs and benefits of cooperative pathogenesis.

A simplified community to enable manipulative study of maize microbiome function

     Plants live in close association with hundreds to thousands of bacterial and fungal species, both on and inside their roots. This diverse and complex microbial community—the plant microbiome—can profoundly affect the health of the host plant. For this reason, plant microbiomes have great promise as a sustainable tool for protecting both crops and wild plants against environmental challenges. However, the enormous complexity of natural microbiomes has been an obstacle to understanding the principles and mechanisms that determine their composition and function. One powerful approach to overcoming this challenge is experimentation with “synthetic communities” (SynComs), which typically consist of dozens to a few hundred known microbial strains, contained within an otherwise sterile environment. SynComs enable precise manipulation of microbiome composition and analysis of the effects on community function. The goal of this project is to create a SynCom specifically for maize and use it to explore the role of microbe-microbe interactions in root microbiome function under drought conditions. Maize is critically important both as a crop plant and a model system in genetics research. However, the existing maize SynCom contains only seven bacterial species, which limits its value and versatility. The proposed experiments will investigate maize root microbiome assembly from farm and prairie soils across a natural precipitation gradient in Kansas (Objective 1), generate a curated collection of microbes isolated from maize roots growing in these soils (Objective 2), and use the resulting SynCom to test how key organisms influence the rest of the microbiome and function of the whole community, in a water-limited environment (Objective 3). The proposed work would be the most thorough study to date of the maize root microbiome response to drought conditions, as well as the first to investigate the role of legacy effects (land-use and historical precipitation levels) on soil microbiome function. It would also increase the number of microbial strains available for maize SynCom experiments by approximately 30-fold, thus massively improving the microbial functional diversity that can be studied. The effects of SynCom strains on maize phenotype and microbiome structure under water-stressed conditions will be directly tested under reproducible germ-free growth conditions. The expanded SynCom may form the basis of a wide variety of follow-up projects, investigating plant-microbiome interactions at levels ranging from genes to ecosystems.

                                          LSAMP student presents MAPS research at the Emerging Researchers National Conference in Washington DC

                                          Emireth Monarrez

                                               Emireth Monarrez didn’t give much thought to doing scientific research when she was in high school even though science came easy to her and she knew "I always I wanted to major in science."  She didn't think student research was even a possibility until her cousin, Areli Monarrez-Valles, mentioned her involvment with the Kansas State University (KSU) Developing Scholars Program (DPS). Hearing about her cousin's DPS research experience sparked her desire to find similar college research opportunities. So, during her freshman year at Seward County Community College (SCCC), Emireth looked for and found the Kansas Bridges to the Future Program (Bridges SSSC). The Kansas Bridges SSSC program is funded by the National Institutes of Health and encourages underrepresented minority students in the biomedical sciences to begin their studies at a community colleges and then transfer to KSU to complete a bachelor’s degree. Through the Bridges program, Emireth worked with SCCC Biology Instructor, Myron Perry, on a research project that focused on methicillin resistant staphylococcus aureus and multi-drug resistant bacteria. This research project led to an opportunity to have her research presented at the Annual Biomedical Research Conference for Minority Students (ABRCMS) in Arizona. Emireth said working on this research project with Mr. Perry “sparked an even bigger interest to continue doing research in different fields outside the biomedical sciences.”
                                              It was through the Bridges SCCC Program that Emireth discovered the KSU Louis Stokes Alliance for Minority Participation (LSAMP) Research Immersion: Pathway to STEM (RiPS) Program. The RiPS program is an 8-week summer research experience at KSU in which students conduct independent research with a faculty mentor. Seeing this RiPS program as an opportunity to explore other areas of science, Emireth chose to pursue a research project in plant microbiology and was paired with Dr. Tom Platt, Assistant Professor of Biology at KSU and plant systems research team member for the Kansas NSF EPSCoR RII Track-1 Award OIA-1656006 titled: Microbiomes of Aquatic, Plant, and Soil Systems across Kansas (MAPS).
                                               Emireth's MAPS research project is titled Characterizing the diversity of agrobacteria on the roots of common sunflowers, Helianthus annuus, at Konza Prairie and she explains her project as follows: “The purpose of my research was to identify and characterize the diversity in the agrobacteria population across plants. I was trying to create a phylogenetic tree that would show if the agrobacteria was largely clonal or diverse. As far as methodology, the first thing I did was collect Helianthus annuus from the Konza Prairie and afterwards sample for agrobacterial isolates. After obtaining agrobacterial isolates I used a semi-selective media to identify that I was indeed working with agrobacteria. After the semi-selective test, I performed a biochemical test, 3-ketolactose test, which would further validate that the isolates were agrobacteria. Then, I streaked purified 360 agrobacteria isolates across 20 common sunflower plants into pure culture and preserved them for future genetic characterization. Lastly, I ran a polymerase chain reaction (PCR) to obtain the DNA sequence of the recA region from the isolates. Unfortunately, I was not able to create my own phylogenetic tree due to lack of time, but I plan to continue my work with Dr. Platt in order to eventulally create the phylogenetic tree and determine if the agrobacteria is diverse or clonal.” As a result of her summer research efforts, this past February, Emireth presented her MAPS research at the Emerging Researcher National (ERN)Conference in Washington DC.
                                          Emireth and Dr. Platt with his research lab team
                                               Emireth said her favorite part of the RiPS experience was learning new scientific techniques “as well as how to better understand a peer-reviewed article.” In addition, she said “I learned how to better communicate with team members and how to be a well rounded scientist in a lab." With regards to the KSU LSAMP RiPS programmatic support, she added "Dr. King had great advice. Her classes…were extremely beneficial and she definitely was setting us up for success." When asked what her favorite part of the ERN Conference was, she said “My favorite part of the experience, aside from getting to see all the sights since I have never been to Washington D.C., was presenting. I loved being able to explain to people what I did the entire summer, as well as being asked what I planned to do next, etc."
                                               Emireth is from Liberal, Kansas and is an active member of HALO, Bridges, TRiO, and Phi-Theta-Kappa (PTK) at SCCC. She also volunteers at the local hospital. After she earns her associate's degree, Emireth plans to transfer to KSU in the fall of 2019. She also plans “to continue to work with Dr. Platt on my summer RiPS project since I did not get to finish it....” At KSU, Emireth plans to either major in Biology or Microbiology.

                                          Former Secondary Science Teacher studies Geomicrobiology and Microbial Ecology with MAPS Researchers

                                              When Christina Richardson graduated with a Bachelor of Arts degree in Geology from Wheaton College in Wheaton, Illinois, she also graduated with a Bachelor of Arts degree in Secondary Education and obtained an Illinois teaching certification. Following graduation, she began her career as a substitute teacher in Illinois, and then later, she became a teacher aid in Indiana. Although, Christina is originally from Indianapolis, Indiana, she grew up in New Delhi, India, so it was not unusual that in June of 2012, she accepted a position in New Delhi serving as an Education Consultant for the Metro Delhi International School.
                                          Christina presenting her research at the
                                          2018 Geological Society of America (GSA)
                                          meeting in Indianapolis, IN
                                               As an Education Consultant, Christina created “the middle school science curriculum and the high school biology curriculum,” as well as developed the science safety guidelines and the school's annual Science Fair. In addition, she taught 6th through 8th grade science and high school biology. After working four years as an Education Consultant, Christina decided she wanted to go back to school to earn a master's degree because, as she explains, “ ... I realized that I missed studying science for myself.” She added that her interest in studying “Geomicrobiology and Microbial Ecology grew through my students’ curiosity in high school biology and my desire to learn about and promote more sustainable agricultural and water management practices around the world.” So, she moved back to the U.S. to pursue a Master of Science in Geology at Kansas State University (KSU).
                                              Now in her second year, Christina is working on her master's project with Dr. Matthew Kirk, Associate Professor in the Geology Department at KSU and a team leader of the Soil Systems research team, and Dr. Lydia Zeglin, Assistant Professor in the Biology Department at KSU and a team leader for the Aquatic Systems research team, both involved with the Kansas NSF EPSCoR RII Track-1 Award OIA-1656006 titled: Microbiomes of Aquatic, Plant, and Soil Systems across Kansas (MAPS).  On November 16, 2018, Christina presented a poster featuring her research at the MAPS All Science Meeting held at the Konza Prairie Biological Station. Christina collaborated on the poster project with a fellow graduate student, Alexandria Richard. The title of their poster was “Impact of Land Use on Groundwater Chemistry and Microbial Communities in the Great Bend Prairie Aquifer.” Within their research project, Christina focused on looking closely at “the soil and aquifer microbial communities in the Great Bend Prairie Aquifer to understand how they are impacted by land use” while Alexandria focused on the “impact of land use on groundwater chemistry in the Great Bend Prairie Aquifer.”
                                          Left: Surveying for soil sampling sites near monitoring wells in south-central
                                          Kansas, and 
                                          Right: Sampling soils at different depths, using ethanol and gloves
                                          to ensure the soil microbial communities remained intact with minimal
                                          contamination of microbes from other sources.
                                               Christina explained what their research addressed as follows: “Microbial species engage in redox reactions that significantly affect aquifer geochemistry and water quality. Previous studies have focused on the impact of land use on groundwater quality as well as on soil microbial communities. However, very little research has been conducted to understand the influence of land use on aquifer microbial communities. In this study, we are examining the relationship between land use and aquifer microbiology in the Great Bend Prairie Aquifer, a portion of the High Plains Aquifer in south-central Kansas. We hypothesized that land use significantly impacts the composition of the shallow aquifer microbial community and that the composition of the groundwater microbiome will be related to the composition of the soil microbiome. To test these hypotheses, we are comparing the shallow aquifer microbial communities to groundwater geochemistry and to soil geochemistry and microbiology in areas of different land use. We have analyzed multiple samples of the soil and aquifer microbiomes to compare the composition and diversity of their microbial communities. In addition, we have measured environmental parameters (e.g. pH, particle size, EC, OM, NO3-, NO2-, NH3, Mg, Ca) in the soil and shallow aquifer at each sampling site. We are currently analyzing our collected data with alpha and beta diversity tests through QIIME and RStudio. Because land use changes many environmental factors (e.g. added nutrients through fertilizers, pesticides, and manure; change in soil structure via cattle or machinery compaction), we expect to see significant correlations between the shallow aquifer and soil microbial communities of cropland compared to those of pastoral sites.”
                                               As for her future plans after graduation, Christina said, “I plan to get some experience in the environmental consulting world while my husband is still in the Army, and I am interested in pursuing more research and higher education in the future. Eventually, I plan to work internationally as an environmental consultant.”

                                          MAPS graduate student studies HABs and Kansas water quality

                                          Janaye Hanschu working on
                                          her first independent research project
                                          as an undergraduate
                                               During the summers of her childhood, Janaye Hanschu would visit the Marion Reservoir located on the Cottonwood River, 3 miles northwest of Marion, Kansas. Because she loved the water, it was a weekly event. Unfortunately, as she got older the lake “would often get shut down due to harmful blue-green algae blooms" (HABs). Harmful blue-green algae is a bacteria know as Cyanobacteria that reproduces rapidly if conditions such as high nutrient and high light levels are present. The dense growth of the algae, or bloom, can produce toxins if it becomes stressed or dies. These toxins impact water quality and are harmful to people, fish, shellfish, marine mammals and birds. According to the 2018 Kansas Water Authority Annual Report to the Governor and Legislature, HABS continue to impact the Marion Reservoir's water quality, and Janaye added, it is “one of the worse lakes in Kansas as far as algae blooms” are concerned. After witnessing, firsthand, the impacts HABs and excess nutrients had on Kansas waterways, Janaye decided she wanted do something about the water quality problems in Kansas.

                                                So, while she was earning a bachelor’s degree in Biology from Kansas State University (KSU), Janaye pursued her research interest in water quality by working for Dr. Lydia Zeglin's in her Microbial Ecology Lab. Dr. Zeglin is an Assistant Professor of Biology at KSU and is a member of the Aquatics research team for the Kansas NSF EPSCoR RII Track-1 Award OIA-1656006 titled: Microbiomes of Aquatic, Plant, and Soil Systems across Kansas (MAPS).
                                               After graduating in the fall of 2017, Janaye continued to work for Dr. Zeglin as a research assistant on another NSF research project titled: RAPIDS: Are biogeochemical responses linked to the microbial composition of a defined nutrient and microbial input to a large river? (DEB #1822960). This project involved a collaboration between the Zeglin Microbial Ecology Lab (KSU) and the Burgin Lab at the University of Kansas (KU). The Burgin Lab is led by Dr. Amy Burgin, Associate Professor of Ecology and Evolutionary Biology (EEB) at KU; Environmental Studies Associate Scientist for the Kansas Biological Survey; and a MAPS Aquatics research team member. The RAPIDS project was designed to study nutrients in the Kansas River.
                                               On November 16, 2018, Janaye presented a poster featuring her RAPIDS research at the MAPS All Science Meeting held at the Konza Prairie Biological Station. The title of her poster was “Do novel inputs to the Kansas River affect the water of sediment microbiome and water chemistry?” She explained her RAPIDS project as follows: “The city of Lawrence bought an old fertilizer plant. The plant contained several gallons of fertilizer dissolved in water. The city needed to dispose of the fertilizer. Initially, the city was selling the fertilizer to farmers to use for their crops. However, the execution was time consuming and a financial burden. As a result, the city got permission from the state and EPA to release the fertilized water into the Kansas River over a time frame of about two months. The release inoculates the water with both nitrogen (nutrients) and microorganisms. This novel input into the Kansas River lead to the question: Does microbial nitrogen processing in the river respond solely to changes in the nitrogen substrate supply, or does changing the microbial community also affect ecosystem-scale biochemistry. We sampled the river every two weeks (in addition to other sampling). At one time point, it was found that there is a microbial community composition (MCC) spike--an increase in microbial diversity--where the fertilizer was being released into the river. The overall MCC was returned to normal by 5 km downstream of the input site, but the microbial types unique to the input can be detected to at least 29 km. There were 23 unique bacterial OTUs in the water downstream of the input, but only 5 of these increased in relative abundance. As for the biochemistry and microbial relationship, for this specific time point, the microbial biochemical processes seem to be turning over the nutrient load at a sufficient rate because the chemical signals are weaker than the microbial signals.” And she said that although "this poster was done on a different grant ... the research was relevant to the MAPS project." While working on RAPIDS project, Janaye became “highly interested in linkages between MCC and biogeochemistry rates.”

                                          in the summer of 2018 which will she will
                                          continue this summer (2019). 
                                               In the fall of 2018 Janaye decided to continue pursuing her research interests in water quality and entered graduate school at KU. Janaye was hired by Dr. Amy Burgin to work as a MAPS graduate research assistant in the Burgin Lab. Janaye explained why she wanted to participate in the MAPS research this way: "I am interested in working on the MAPS research because we live in this delicately interconnected environment that needs to be understood in order to preserve it. Humans are changing our Earth's ecosystem at a rapid rate and understanding out interactions between aquatic, plant, and soil microbes could be a key in establishing policies and practices for a better future." And she added, “During the MAPS project, I hope to better understand connections between the MCC in harmful algae blooms (HABs) and nutrient availability/limitations to be able to better understand the production of cyanotoxins by cyanobacteria.” Her MAPS research will involve conducting a mesocom tank experiment in the summer of 2019. She explained the experiment as follows, “Large tanks will be inoculated with Kansas lake water and different nutrient limitations will be imposed on the tanks. Also, different forms of nutrients, such as nitrogen, will be observed. We will look at which kind of nutrients influence cyanobacteria growth and cyanotoxin production.”
                                          Janaye is from McPherson, KS and is a first year EEB Master's student at the KU. As for her future plans, she hopes to continue a career in research and/or outreach.
