Research
Interests:
Work in my
laboratory emphasizes the behavioral, nutritional, population, and
community ecology of mammals, but my students have worked on birds,
insects, and amphibians as well. We usually test hypotheses by making
field observations and by conducting field experiments, although many
samples need to be processed and nutritional experiments often must be
done in the laboratory. Specific areas of interest include:
-
Nutritional
ecology of herbivorous mammals--behavioral, morphological, and
physiological responses of mammals to changes in food quality.
-
Interactions
of herbivorous mammals and plants--effects of plants on habitat
selection, demography, and density of mammals and effects of mammals
on vegetation.
-
Direct,
indirect, and interactive effects of environmental factors on the
population dynamics of small mammals--effects of changes in behavior,
nutrition, predation, and interspecific competition on demography and
density.
-
Effects
of landscape factors on local populations of small mammals--influence
of quality, size, isolation, and relative abundance of favorable
patches of habitat on movements and patterns of population dynamics.
