Brief Description of Research Interests

Behavioral Ecology

Detailed Research Interests

I have three primary research interests. My first area of interest is behavioral ecology. I have published on population biology and food limitation in arachnids, food web structure, winter bird distribution, and migratory shorebird populations. I am especially interested in the influence of temporal and spatial variation in prey populations on the biology of their predators. My second area of interest is biodiversity assessment. I am interested in the influence of habitat structure and land-use history on the assemblages of species in particular areas. The current project in this area is the Ohio Spider Survey. My third area of interest is the biology of vocal behavior in birds, emphasizing the evolutionary significance of geographic variation in bird song. I have published on analytical methods for analysis of bird song structure, the significance of geographic variation in bird song, and the role of bird song in territorial maintenance.
