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.

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 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.”

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.”
