John McCarty
I have a number of research interests in ecology. Much of my work has been focused on the ecology, behavior, and evolution of birds. I am especially interested in designing research that meets the needs of policy-makers and resource managers, while also addressing basic questions in ecology. I currently have several areas of research related to the ecology of birds. If you are interested in seeing the work I have completed, visit my "old" research page and my publications page.

A major focus of my lab's research has been on grassland birds breeding in an ecosystem heavily modified by agriculture. This research, begun in 2002, is being conducted in collaboration with L. LaReesa Wolfenbarger, an Associate Professor of Biology at UNO. Our research recognizes that native prairie has been heavily impacted by human activities over much of North America. Where grassland species persist, agricultural ecosystems tend to be in close proximity. How agricultural ecosystems are managed is likely to have a strong influence on the suitability of grassland habitats for breeding birds. The research program combines population-level studies of Dickcissels (Spiza americana) with community-level work looking at the grassland bird community in relation to vegetation and food supply. Our work is being supported by the US Department of Agriculture and the US Fish and Wildlife Service. To learn more about the Grassland Birds Project, follow this link.

Migrating Shorebirds and Agriculture
The second main focus of research in our lab is on the stop-over ecology of shorebirds migrating through Nebraska's Rainwater Basin in the spring. This work is being done in collaboration with L. LaReesa Wolfenbarger here at UNO and with Joel G. Jorgensen of the Nebraska Game and Parks Commission. This work developed out of research Joel's did for his master's thesis in our lab (Jorgensen, J. G. 2007. Buff-breasted Sandpiper (Tryngites subruficollis) Abundance, Habitat Use, and Distribution During Migratory Stopover in the Rainwater Basin, Nebraska. M.S. Thesis, Department of Biology, University of Nebraska at Omaha). We are focusing on how rare Buff-breasted Sandpipers use agricultural lands while resting during their spring migration between South America and their arctic breeding grounds.

Graduate Student Research in the McCarty-Wolfenbarger Lab
LaReesa Wolfenbarger and I co-advise all of our graduate students. While much of the work in our lab focuses on birds, recent graduate students have asked questions about butterflies, herbivorous insects, and nest predators such as snakes and small mammals.
