Graduate research from the LTER shows that prairie strips planted within agricultural monocrops are not an “ecological trap” for native pollinators - but they also don’t reduce insecticide runoff that may pose a threat. Agriculture is essential, but the lack of biodiversity in farmland can create ecological barrens. Prairie strips - the long, thin strips of tallgrass prairie vegetation planted adjacent to agriculture - have potential to bring ecosystem services into agricultural spaces, such as increased pollination, enhanced microbial diversity, and containment of nutrient

Long-term data provides new perspective on agricultural impacts on arthropod diversity
A 30-year study on ground beetles from the KBS LTER reveals significant declines in beetle abundance and community composition in agricultural systems. Rates of decline were must faster in fields with chemical inputs, compared to organic systems. Data that spans multiple decades has the potential not only to reveal long-term trends, but also provide answers to new and exciting questions. This is particularly important in agricultural systems, where the impacts of different management practices can take many years to be seen. Recent research from by KBS LTER graduate student Cindy Fiser
Graduate research from the KBS LTER explores grassland resilience to climate change
Two decades of data on plant communities and weather from the LTER Main Cropping Systems Experiment show that extreme dry and wet years reduce species richness (the number of species) but increase evenness (how evenly abundant the species are). Because richness and evenness also increase long-term stability and resistance to extreme precipitation events, these changes to communities might have long-lasting effects on the resilience of plant communities to the increasingly variable precipitation patterns expected in the future. While the focus of climate change is often on warming
Award-winning graduate research highlights previously unrecorded benefits of prairie strips
Three years of butterfly surveys across the LTER Main Cropping Systems Experiment show that agricultural plots where 5% of cropland was converted to prairie harbor unique species and have a greater abundance of butterflies than plots without prairie. This work earned Lindsey Kemmerling, who completed her Ph.D. studies at W.K. Kellogg Biological Station in the Haddad Lab, the 2023 Royal Entomological Society Journal Award. As agriculture increases in intensity across the U.S., finding ways to conserve ecological systems while supporting crop production has become critical. Keeping native
New prairie strip partial budget tool from MiSTRIPS team
Conservation practices require a significant investment in time and money. There are often large implementation costs, learning curves, and labor required, all of which might prevent farmers and landowners from being able to adopt these practices. Additionally, when there are no tangible payments or products, the financial benefits may seem invisible. Yet, conservation practices provide many benefits to the cropping system, often by improving soil health, protecting water quality, and increasing yield stability. Because of this, farmers are often eligible for payments which can offset or even
KBS LTER Scientists, Robertson and Sprunger, named 2024 ESA Fellows
The Ecological Society of America has announced its 2024 Fellows, with Drs. Phil Robertson and Christine Sprunger of the KBS LTER amongst the members. The Society’s fellowship program recognizes the many ways in which its members contribute to ecological research, communication, education, management and policy. This year, the ESA Governing Board has confirmed nine new Fellows and ten new Early Career Fellows. Fellows are members who have made outstanding contributions to a wide range of fields served by ESA, including, but not restricted to, those that advance or apply ecological
Drought effect on pore structure in soils: Reflections from an LTER Fellow
Goutham Thotakuri is a graduate student in the Kravchenko lab at Michigan State University. His research is focused on the study of carbon transfer between various cover crop species and soil carbon sequestration. Recent changes to our climate dynamics have brought on alarming drought conditions in many parts of the world. Since we cannot control the climate, we need to prepare our agricultural systems for adversity. One way to do this is through understanding the soil's hydro-physical and biochemical processes. We can identify critical factors influencing drought resilience by
Exploring the effects of multiple crises on the global food trade system: Reflections from an LTER Fellow
Nan Jia is a graduate student at Michigan State University's Center for Systems Integration and Sustainability, Department of Fisheries and Wildlife, and Environmental Science and Policy Program. Her PhD research seeks to uncover how the multiple crises affect global food trade system dynamics. She worked closely with Jack (Jianguo) Liu and members of the lab to reveal the impact of different crises on different stages of trade such as production, handling, transportation, and consumption by using production data, trade data, supply chain data, and consumption data. The interactions between
Trials and tribulations of a PhD student: Reflections from an LTER Fellow
Moriah Young is a graduate student at the Kellogg Biological Station and a member of Phoebe Zarnetske's Lab. Her PhD research seeks to understand the effects of climate change on soil biota, plant, and herbivore interactions. Using a combination of field and greenhouse studies, Moriah works to understand the ways in which the composition and structure of soil microbial communities respond to warming and drought, as well as describing the role that the soil microbial community has on plant traits, stress responses, and insect preferences in the presence of warming and drought. I went into
Pools of phosphorus across the LTER: Reflections from an LTER Fellow
Ethan Weinrich is a graduate student in MSU's Department of Plant, Soil and Microbial Sciences, advised by Sieg Snapp. The Challenge Soils contain the largest pool of phosphorus on Earth. Yet, farmers need to add phosphorus to their fields to help crops grow. This is called the Phosphorus Paradox: there is so much phosphorus in soils, yet plant growth is limited by this nutrient. The tricky part is that most of the phosphorus in soils is locked away in forms not available to plants. How can plants access the phosphorus they need to grow? Phosphorus minerals in soil can be broken
