Field of research
My
research involves understanding the factors that affect the abundance and
diversity of wild species as they are affected by features of the
landscape. The work involves a range
scales from the perception of individual animals to the impact of several
entire populations upon each other.
Typically,
I prefer to work with small mammals.
However, I have also conducted field work on plants, snails, butterflies,
anurans, and deer. In addition to field
work, I develop models to test basic hypotheses concerning the ways in which
different levels of ecological organization can affect higher levels of
organization. Principally, this involves
modeling behavioral traits to determine their importance in population or community
processes that occur over large spatial and temporal scales.
Although
I do not frequently focus on endangered species or game animals, I and my
students and postdocs have worked on three federally endangered species
(Alabama Beach Mouse, Iowa Pleistocene Snail, Mount Graham Red Squirrel), and
whitetail deer.
