I have studied a variety of animals and habitats: mammals, birds, grasshoppers, spiders and brine shrimp in grasslands (Montana), desert shrubland (Australia), boreal forest (Michigan), rainforest (Puerto Rico), tundra (Alaska) and saline lakes (Utah). Results have furthered conservation and sustainable harvesting.

My students and I have been conducting long-term studies in grasslands at the National Bison Range in Montana (since 1978 - 35 years) and at Great Salt Lake in Utah (since 1995 - 19 years). Newer projects are in Puerto Rican rainforest and in forests at the University of Notre Dame Environmental Research Center (Michigan).

My research philosophy has several major themes. First, I construct theories and test them by conducting observational and experimental field studies. Second, I apply a reductionist approach to understand higher level processes, e.g., can community ecology be understood by population processes and can population processes in turn be understood by behavioral/physiological processes. Finally, I attempt to employ my studies of ecological principles to address applied problems (e.g., conservation) and provide insights in other disciplines (e.g., anthropology/archeology).

I have particularly focused on foraging theory as it relates to population dynamics, interspecific competition, predator-prey dynamics and nutrient cycling in ecosystems. In these studies, herbivores as large as bison and moose and as small as grasshoppers and brine shrimp have been employed. In turn, predators as large as mountain lions and as small as birds and spiders are studied. With this diversity of herbivores and predators, ecological patterns related to body mass have been explored. Findings from these studies have been applied to examine population viability for conservation, pest control programs of herbivores that may be reducing nutrient cycling and thereby, plant production in ecosystems, and prehistoric human hunter-gatherers and how they influenced their environment.

The combination of fieldwork and theory in ecology is not only intellectually challenging and addresses issues that are relevant to society; it is also great fun.
