Habitat Ecology ...a unifying theme
I am fascinated by all aspects of wildlife Habitat Ecology--from the theoretical to the practical. Habitat ecology is the study of how animals interact with their habitats, which my lab investigates by identifying animals' critical resources and the factors that constrain their use. Such studies advance our ecological understanding and refine our conservation and management efforts. Though much of my work focuses on on songbirds, I purposefully work with a variety of taxa to better understand emergent relationships between animals and their habitats. Therefore, students in my lab work on a diversity of study systems, yet share a unified focus on habitat.
Habitat models are mathematical or cartographic constructions that wildlife ecologists use to predict & understand animals' distribution in space and time, usually in reference to types of vegetation. They are especially useful for land managers because they can help assess the impact of proposed land use changes. Many habitat models incorporate Geographic Information System (GIS) technology. I am interested in both the construction of new wildlife habitat models and evaluation of existing models.
I have an ongoing interest in the ecology of birds in Jamaica, where my dissertation research was focused. I am particularly fascinated by how migratory and non-migratory (resident) birds are distributed among natural and agricultural habitats, and how their populations are influenced by food supply. Understanding the distribution patterns of birds is important for conservation efforts, and it also offers insights into the ecological processes enabling migrant and resident birds to coexist with limited resources.
Ecosystem services are processes provided by nature that help sustain and fulfill human life. Some ecosystem services are provided mainly by plants - such as the regulating services of air purification and of carbon sequestration. Other services are provided by entire ecosystems - such as erosion control, moderation of weather and climate. Cultural values such as the provisioning of aesthetic beauty and spiritual stimulation can also be considered "services" provided by nature. In addition, some animal species provide important ecosystem services - such as pollination, pest control, seed dispersal, and waste removal. These animal-delivered ecosystem services can be extremely important both ecological and economically, and they offer a powerful incentive for wildlife conservation. My students and I examine ecosystem services provided by wildlife, and I am especially interested in examining how mobile organisms provision ecosystem services across a landscape.
Interdisciplinary studies related to wildlife
I believe there is general consensus that higher education's most fundamental purpose is, in David Orr's words, to build a citizenry prepared to work toward achieving healthy, resilient, just, and prosperous human communities that are living within their means economically and ecologically. Many different skills and disciplines must be brought to bear: economics, politics, and the natural, environmental, and social sciences. The classic humanities are critically necessary as well, to provide the context, for example, of how history, philosophy, and the arts both reflect humanity's past and shape its future relations with the natural world upon which our fate now so clearly depends.
I am interested in examining interdisciplinary questions relating to sustainability and wildlife. As such, I am a member of the Environment and Community (E&C) program here on campus, which is an interdisciplinary Master's of Arts program. Students interested in examining social science research questions related to wildlife conservation or pursuing projects that lie at the intersection of social movements and conservation work should contact me about this program.
