MSU Researchers found a 22% decline in butterfly populations from 2000 to 2020. Their work explores how prairie strips in agricultural areas can support insect populations. Dr. Nick Haddad, Director of the Kellogg Biological Station Long Term Ecological Research Program, co-led a research project with Dr. Elise Zipkin, director of MSU’s Ecology, Evolution and Behavior Program, to evaluate the state of butterfly populations across the United States. They report that from 2000 to 2020, the total butterfly abundance has fallen by 22% - shocking rates that demand action. The Haddad lab c
Prairie strips: a refuge in an agricultural desert or an ecological trap for native pollinators?
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 runoff
The ABC’s – Agriculture, Beneficial Beetles and Conservation: Reflections from an LTER Fellow
Cynthia Fiser is a graduate student in Doug Landis's lab in the Michigan State University Department of Entomology. Her research looks at the impact of perennial prairie strips on the dispersal of ground beetles in row crop agriculture. Rolling hills of wheat, corn and soybean are a beautiful and nostalgic feature of the summer landscape in the Midwest. Here, agriculture is as much a part of the culture as the economy – anyone who attends a county fair would agree! However, the pressure placed on our agricultural landscapes to meet global demands for food, fuel and fiber takes a toll on
Species interactions in prairie strips: Reflections from an LTER Fellow
Graduate researcher, Alice Puchalsky, is a Ph.D. student in Dr. Nick Haddad's lab at Michigan State University. Her research focus is on moths, butterflies, and interaction networks. When I began graduate school, I did not imagine myself eagerly watching a caterpillar writhe around in a plastic cup, wondering about its fate. But, that is where I found myself this past summer. I also did not imagine the delight I would feel in checking on that caterpillar the next day and finding that approximately 30 very small parasitic flies had emerged from that caterpillar’s body. I was hoping that m
Designing agricultural landscapes to provide more than crops
Agriculture is the defining feature of many rural North American landscapes. Over time, a focus on productivity and large-scale cultivation of commodity crops has resulted in agricultural landscapes dominated by large, homogenous fields, such as the corn and soy that blanket the Midwest. But agricultural landscapes provide more than just the crops grown on them. They also offer animal and plant habitat, clean our water and air, and capture carbon in the soil—a host of services often termed ecosystem services. Many key co-benefits are thanks to insects and other arthropods: they pollinate c
Using prairie strips to understand the value of diversifying agricultural landscapes: Reflections from an LTER Fellow
MSU graduate researcher, Lindsey Kemmerling, is a PhD student in Dr. Nick Haddad's lab at Michigan State University's Kellogg Biological Station. Society today faces three immense ecological challenges: preventing the loss of biodiversity, adapting to climate change, and sustainably supporting a growing population. Humans have caused a global biodiversity crisis, with new studies continuing to reveal stunning rates of biodiversity decline across the entire tree of life. Simultaneously, we are presented with the challenge of sustainably and equitably supporting a growing human
