Why study animal-ecosystem links?

For me, life is about relationships – personally with family, community and place, professionally among students, colleagues, and the species and systems we study, and metaphysically between humans and the earth. My overarching research interest, which is focused understanding the relationship between species and ecosystem processes, reflects this perspective.  This interest has required working across scales from understanding a species’ evolution and physiology to population ecology, community ecology, and ecosystem science.  This is important because it critically informs management decisions and conservation science. I am convinced that personal appreciation, public support, and effective conservation start with the understanding of animal-ecosystem relationships.

Among the major questions in my lab are: 1) How and under what circumstances do species control the distribution of energy, nutrients, and contaminants within and across ecosystems? and 2) How can we use biochemical indicators of energy and nutrient flow to understand and conserve organisms? My main theoretical work is focused on understanding how mammalian predators control ecological heterogeneity and how herbivores influence aquatic-terrestrial connectivity via effects on key ecosystem processes.  My applied work currently involves using stables isotope techniques to better understand animal ecophysiology and migration to inform conservation and management.
