Dr. Isbell is the associate director of Cedar Creek Ecosystem Science Reserve and an assistant professor in the Department of Ecology, Evolution, and Behavior at the University of Minnesota. He investigates how global environmental changes alter plant communities and ecosystem processes, and how both ecosystems and people depend on biodiversity. This research builds on previous studies of biodiversity–ecosystem functioning relationships, biodiversity–stability relationships, nutrient enrichment, land use changes, and ecosystem services.

Dr. Cowles is interested in the theoretical links between coexistence mechanisms – the reasons there are so many species to begin with – and the consequences of these coexisting species – biodiversity – for ecosystem functioning. Past projects include examining the role of plant-soil feedbacks in the diversity-productivity relationship and ecosystem responses to warming. She co-led an NSF LTER synthesis working group at NCEAS that is scaling-up biodiversity analyses. View her profile on Google Scholar.
Dr. Zirbel explores how plant functional traits structure the assembly of plant communities and functioning of ecosystems undergoing restoration. Focusing on improving restoration success by applying knowledge from basic ecology research while also using restoration as a system to test community ecology and diversity-ecosystem function theory. His postdoctoral research asks how grazing by bison reduces fire intensity and competition from dominant grasses to promote oak regeneration and the diversity of savanna species.

Cristy is interested in understanding the mechanisms that lead to coexistence and maintain high levels of plant diversity. Her current research studies how soil microbial communities respond to nutrient enrichment in grasslands, as well as the role of plant-soil feedbacks in the recovery of biodiversity after perturbations.
Maggie is interested in the effects of plant functional traits on the diversity of wild bee communities. She seeks to understand how climate change and habitat fragmentation can alter patterns of plant phenology and ultimately impact pollinator communities in the future. The findings of her work will have conservation and management applications.
PREVIOUS LAB MEMBERS
Dr. Kimmel was a PhD student in our lab. She is now a postdoc at Johns Hopkins University. She explores how human actions are altering biodiversity and community composition by utilizing both long-term data sets and theory. She is interested in the many ways we can describe the community structure and how these different measures may give us insights into how ecosystems may function in the future. To read more about her work, check out her website here.
Zhiyuan was a visiting PhD student in our lab, coming to us from Peking University in China. He is interested in exploring the consequences of global changes, such as warming and precipitation alteration, on alpine grassland ecosystems on the Tibetan Plateau. His current research investigates how plant communities, including their temporal stability and their community composition and assembly trajectories, would respond to anthropogenic climate changes.
Dr. Kazanski was a NatureNet Postdoctoral Fellow in our lab. She is now a Sustainable Grazing Scientist for the North America region at The Nature Conservancy. She investigates how global environmental changes and land management practices affect soils and ecosystem carbon storage. Her research addresses the potential for enhancing soil carbon storage in grasslands and rangelands through specific grazing practices. Visit her website or view her Google Scholar Profile.
Dr. Liu was a visiting scholar in our lab, and he is currently an associate professor in the School of Life Sciences at Northeast Normal University in China. He has a wide range of research interests and experiences, including investigating plant response to animal saliva and geographical variation of seed mass across Canadian Boreal Forest. His current work mainly focuses on the response of grassland ecosystem processes and functioning to global change (e.g. nitrogen deposition) and human activity (e.g. grazing).
Dr. Palmer was a postdoctoral research associate in our lab, investigating the cascading effects of wolf recolonization on soil and plant communities at Cedar Creek. She is currently a postdoc at Princeton. Her research explores the direct and indirect effect effects of predators on prey behavior, prey demography, and ecosystem functioning. She investigates anti-predator decision-making in large herbivores in response to predators such as wolves and lions and works intensively with citizen scientists to classify data from large-scale camera trapping projects.

Dr. Craven was a postdoctoral research fellow in our lab. He is currently an associate professor at Universidad Mayor in Chile. Some of his current work in our lab considered whether plant diversity can buffer ecosystem processes under perturbations. Visit his website or view his Google Scholar profile.
