Current Research

My current research involves assessing and modeling the effects of future climate change and stressors on at-risk species, including the polar bear, northern spotted owl, Pacific walrus, and other high-latitude wildlife species. I am also developing and applying structured decision-aiding models and methods for informing listing decisions and threats evaluations of at-risk species and injurious invasive species; assessing causes and effects of sea level rise on coastal marshes; modeling the influence of alternative old-forest reserve designs on the viability of northern spotted owls; and developing new ways to bridge ecological and cultural values of subsistence resources used by indigenous peoples of southeast Alaska. I am also continuing studies on potential effects of climate change on the ecological and cultural functions of tree species in northeast India.

Research Interests

Applied science research and technology development and application projects dealing with old-forest ecology, modeling of rare and little-known species, biodiversity assessment, ecologically sustainable forest management, development of a research framework on key ecological functions of plants and animals.

Past Research

My past studies have included field research of bird communities in young and mature Douglas-fir forests of Klamath Mountains, California; field research on lichens, mosses, vascular plants, and invertebrates of old-forest remnants, forest plantations, grazed and ungrazed riparian areas, and recent forest fires in the southern Washington Cascades and eastern Oregon (the Old Forest Remnants Study); analysis of vocalizations of the African Wood Owl throughout Africa (potentially identifying at least a new subspecies of owl); and developing new analysis methods for determining age class of martens from non-invasive samples.

Why This Research is Important

Collectively, my research provides empirical, theoretical, and modeling approaches to a variety of questions pertaining to at-risk species conservation.
