Effects of Habitat Alteration on Population Regulation in Aquatic Organisms: From Fish to Frogs
Linking ecosystem changes to the regulation and structure of populations is essential for management (e.g., estimating harvest potential) and for conservation of species. I examine these issues using a mix of field work, experimentation, and simulation modeling. This seminar details two case studies from my research (1) impacts of intermittent hypoxia on east coast estuarine populations, Atlantic croaker (Micropogonias undulates) and blue crab (Callinectes sapidus), and (2) impacts of beaver on the distribution of lentic habitat in western Montana and associated differences in Columbia spotted frog (Rana luteiventris) population structure.
Dr. Lisa Eby is an Assistant Professor of Aquatic Vertebrate Ecology at The University of Montana. She received her B.S. in Zoology and M.S. in Limnology and Oceanography from the University of Wisconsin in Madison and Ph.D. in Aquatic Ecology from Duke University. After working briefly as a postdoctoral researcher at Arizona State University, she was hired by the College of Forestry and Conservation here in Montana. Her previous research has spanned a range of questions and ecosystems from examining chronic stress (low oxygen zones) and catastrophic disturbances (floods and hurricanes) on individuals, populations, and communities in estuaries, to exploring the role of population shifts on food web interactions and trophic transfer in lakes, to analyzing long-term community changes in desert stream fish communities
