Comparing structure and diversity of vertebrate and invertebrate communities in a landscape mosaic: a first step in evaluating and conserving Nicaragua's biodiversity and promoting sustainable ecotourism in critical watersheds in a rapidly changing climate, in collaboration with USFS/IITF-International Cooperation (Gerald P. "Jerry" Bauer) (Major non-Forest Service Collaborators: Conservation NGO Paso Pacifico (Sarah M. Otterstrom); Central American University (UCA, Marvin A. Torrez); Fundacion Cocibolca (Jose Manuel Zolotoff, Roger Mendieta).

I am a research ornithologist and have been with the USDA Forest Service’s International Institute of Tropical Forestry for 38 years. I am stationed at the Sabana Research Field Station in the Luquillo Experimental Forest (El Yunque National Forest) in northeastern Puerto Rico. My research, natural resources management, and community outreach interests are broad, ranging from avian morphometrics, life histories, migratory bird ecology and population dynamics, to sustaining the biodiversity of vertebrate and invertebrate fauna and forest health throughout the Neotropics in a constantly changing climate by saving rare, often endemic and endangered animals from extinction and their habitats from destruction or alteration, including anthropic intervention. Over the years, I have written some 200 scientific articles and technical reports and have trained hundreds of biologists, natural resource stewards, including eco- and avetourism guides, in the principles and techniques of wildlife ecology, population surveillance, avian community dynamics, ectoparasitism, and bird identification (audio-visual recognition) throughout the Caribbean and Mesoamerica. As a result of my mentoring and technical training, several private reserve owners and nature tour guides in Nicaragua have increased their livelihoods through eco- and avetourism revenues. More recently, I have broadened my scope to include urban forestry by initiating avian research in green areas as part of the USAID/USFS-IITF Santo Domingo ULTRA project in collaboration with David King (Research Wildlife Biologist) and Susannah Lerner (Urban Ecologist) at the USFS Northern Research Station located on the campus of the University of Massachusetts, Amherst.
