Research Interests

I'm interested in population/community ecology, particularly structural aspects of community ecology involving factors that limit membership in communities. Basically, I want to know why everything isn't everywhere. Answers at all scales (historical, geologic, continental, landscape, individual, cellular) are of interest. Questions involving species interactions (e.g. good old competition!) are especially fun. Although my primary interest is birds, my interests are question driven (population/community ecology), and are not limited to just birds.

I am interested in research in all areas of biology. and participate in a variety of research projects by providing statistical analysis.

I conducted a long-term project on the Voorhis Ecological Reserve here on campus. In 1981, a wildfire burned part of the Reserve, and we (i.e. me and my graduate students) started looking at what birds utilize the burned area compared to a nearby unburned area. Unfortunately there are not data continuously from 1981 - some graduate students actually expect to graduate! We have substantial data (265 field visits) from 1983 through 2003. A manuscript resulting from the project has been accepted for publication by Western Birds, and will appear in the first issue of 2013 (44(1)).
