Reversing ecosystem disservices caused by agriculture: drivers of belowground recovery during grassland restoration

Main Speaker: Dr. Sara Baer

Senior Scientist and Director , Kansas Biological Survey and Center for Ecological Research

Dr. Sara Baer
Dr. Sara Baer

Speaker's Bio

My primary research interest is the application of ecological theory to restoring ecosystems, particularly grassland. The Baer Lab studies above- and below-ground changes in structure and function during ecological restoration in response to environmental heterogeneity, interannual variability in climate, and intraspecific variation in population sources of dominant species. Much of our research has focused on agroecosystems restored to tallgrass prairie. We have found slow changes in total soil carbon pools on decadal scales, dependent on soil texture, but rapid recovery of easily decomposable organic matter pools that tie up available nitrogen as restoration proceeds. Different ecotypes of dominant species used in restoration can differentially affect species composition and traits with consequences for ecosystem processes. Some of these studies span multiple decades and demonstrate that restored grasslands are dynamic ecosystems both above and below ground, and our knowledge of these ecosystems remains in its infancy.

Speaker's Bio

Dr Deb Bathke

In 2008, Dr. Bathke relocated from New Mexico to join the NDMC, the University of Nebraska-Lincoln’s School of Natural Resources and Department of Geosciences. Bathke spent the previous three years as the assistant state climatologist in New Mexico, where she chaired the state’s Drought Monitoring Working Group. She represented New Mexico in the Climate Assessment for the Southwest program, or CLIMAS, which is one of the National Oceanic and Atmospheric Administration’s Regional Integrated Science Assessment programs. Among the projects she collaborated on were adapting the Dynamic Drought Index for Basins in the Carolinas to the Southwest; implementing a western version of the AgClimate Tools developed by the Southeast Climate Consortium; and convening technical workshops on tree-ring reconstructions of streamflow. Bathke is supervising ongoing student research on urban landscaping and drought, and is on the Program Implementation Team of the National Integrated Drought Information System.

Dr. Tonya Haigh

Dr. Tonya Haigh is a Research Assistant Professor and the Social Science Coordinator and Project Coordinator for the National Drought Mitigation Center at the University of Nebraska - Lincoln. Dr. Haigh’s research focuses on the adaptive capacity of agricultural producers and others to cope with drought. Her research connects social science with climate science by informing the development of stakeholder-driven resources and tools. Dr. Haigh has worked with ranchers, advisors, and researchers to develop the Managing Drought Risk on the Ranch website and has provided social science expertise to the development of climate decision support tools for Corn Belt producers and specialty crop growers. Dr. Haigh’s academic and research expertise includes social theory related to climate risk management, survey development and administration, quantitative data collection and analysis, and qualitative data collection and analysis. Project management expertise includes outcome-based planning and evaluation.

Dr. Jakub Holuša

Speaker's Bio

Jakub holds a PhD in Physical Geography from Masaryk University in Brno, Czech Republic. His research primarily focuses on cold-climate aeolian dunes and their (palaeo-)environmental reconstruction in both past (Czech Republic, Slovakia) and present-day (Iceland, Antarctica) periglacial environments.

Seeking new challenges, he was awarded a Fulbright postdoctoral scholarship in 2026, allowing him to study the largest dune field in the Western Hemisphere, the Nebraska Sand Hills, under the supervision of Paul Hanson. In addition to aeolian research, Jakub has been involved in studies of glacier mass balance, proglacial environmental dynamics, polar soil development and biomedicine in Iceland and Antarctica.

In his free time, Jakub enjoys listening to rock music and cooking. He is a passionate soccer player and also enjoys playing volleyball, cycling, kayaking and hiking.

Dr. Louis Nastasi

Speaker's Bio

Dr Nastasi's work focuses on systematics of gall wasps (Hymenoptera: Cynipidae sensu lato) and their natural enemies (primarily Chalcidoidea), integrating molecular and collections-based methods to elucidate patterns in biodiversity and evolution, delimit and describe new taxa, and produce diagnostic resources such as identification keys. Ongoing projects emphasize the robust herb gall wasps (Aulacideini),slender herb gall wasps (Phanacidini), usurper gall wasps(Ceroptresini), and various gall wasp parasitoids (Eurytomidae and Ormyridae). Emerging projects involve gall wasp pests in crop systems and evaluation of gall wasps’ ability to delimit host plant taxa.
