My research focuses on three themes: the ecology of amphibians and fishes in headwater stream basins in managed forests; the taxonomic and distribution patterns of the amphibian chytrid fungus; and the conservation biology of amphibians, reptiles, and turtles.
Conservation biology, behavioral ecology, population and community ecology. Effects of forest management practices, landscape designs, and policies on aquatic-dependent organisms. Interaction of climate variation with species' ecology and land management practices. Development of new research paradigms engaging multiple partners.
My past studies have explored the reproductive behavioral ecology of frogs and toads.
Why This Research is Important
Over one-third of amphibians and almost 50 percent of turtles are threatened with extinction worldwide, yet we know very little about their general ecology and the main threats that are affecting them. Both taxonomic groups are considered ideal indicators of environmental degradation owing to their reliance on both aquatic and terrestrial habitats and their central position in food webs. Ecological and conservation biology research can aid management decisions regarding these iconic faunal groups, preserving them for generations to come.
