A recent study from KBS students suggests that climate warming can offset insect damage in tall goldenrod, potentially making this already aggressive prairie plant even more dominant as temperatures rise. Climate change may reduce yields of crops like corn and soybeans, but it can also give some plants an edge. That’s one of the takeaways of a recent study of tall goldenrod, a common wildflower that runs rampant in fields across its native range in North America and other parts of the world where it has been introduced. Many goldenrod plants are pocked by tumorlike growths, called
Graduate research from the KBS LTER reveals plant traits that predict ecosystem stability
Researchers showed that functional traits of plants can help explain why some grasslands remain productive over many years, but are less useful in understanding how ecosystems respond to individual disturbances. As climate change brings more frequent droughts and increasingly unpredictable weather, one of the biggest questions facing scientists is how ecosystems will respond. While some ecosystems recover quickly from environmental stress, others struggle to remain productive over time. Understanding what makes ecosystems resilient is becoming increasingly important as managers work to
Graduate research from the KBS LTER highlights the role of drought in altering plant-environment interactions
Through an experiment that simulates future climate change conditions within the KBS LTER, researchers found that drought strongly affects the chemical compounds released by goldenrod, suggesting that climate change could significantly influence how ecosystems function. Though you might not be able to see it with the naked eye, plants are constantly interacting with their environment. One way they do this is through the release of volatile organic compounds (VOCs) – chemical signals that help them communicate and react to both living and non-living factors around them. These VOCs form the
Nature-based climate solutions are a powerful tool to reverse the warming caused by deforestation
Deforestation has intensified global warming, but a new study out in Nature Communications Earth and Environment finds restoring forests and adopting sustainable land-use practices can reverse the damage while benefiting both people and nature. A new study published in Nature Communications Earth and Environment reveals that when land managers implement nature-based climate solutions, they can significantly counteract the climate-warming effects of past deforestation. The research, led by ecologists and climate scientists at Michigan State University’s Department of Plant, Soil, and Micr
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
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
Area educators invited to Kellogg Biological Station K-12 Partnership’s Summer Institute
Hickory Corners, Mich. — Teachers and informal educators of K-12 students are invited to engage in science teaching professional development this summer at the W.K. Kellogg Biological Station. The 24th annual K-12 Partnership Summer Institute is set for 9 a.m. to 3:30 p.m. Tuesday, June 20, through Thursday, June 22. Registration is now open! This year’s theme is “Our Changing Planet, Classrooms to Ecosystems,” and will include scientific talks by Dr. David Karowe, Dr. Lauren Sullivan and Naim Edwards. Each morning’s science talk will be followed by a series of interactive and
Disentangling the complex effects of climate change on above and belowground communities: Reflections from an LTER Fellow
Graduate researcher, Moriah Young, is a Ph.D. student in Dr. Phoebe Zarnetske’s lab at Michigan State University. The lab uses open top chambers (OTCs) to study how biotic interactions and climate change directly and indirectly affect community structure and function at the KBS LTER. Climate change is a pressing threat to ecosystems around the world. From warmer temperatures to more unpredictable rainfall, climate change has shown to have a myriad of effects on ecosystems. Most research has focused on direct effects of climate change on species. For example, how does warming a
