Research Interests:

I am interested in understanding the effects of human-caused global changes on wildlife populations and the communities, ecosystems, and landscapes they inhabit. Global change consists not only of climate change but also numerous other impacts humans have on the environment. The spread of invasive species, the emergence of infectious diseases that affect animals and humans, the destruction and degradation of habitat due to urbanization and other land cover and land use changes, and accidental mortality of wildlife associated with human activities are all types of global change.

Research in the Loss Lab focuses on several of these aspects of global change. We study a wide variety of taxa and research questions, with many of our studies focusing on birds. We address both applied and basic questions related to ecology, natural resources management, and conservation biology, and we employ a variety of methodological approaches, including observational and experimental field studies, systematic reviews of previously collected data, and statistical and spatial analyses.

Current research in my lab includes studies of: (1) human-caused wildlife mortality, including predation by domestic cats and collisions with manmade structures, (2) impacts of invasive earthworms on soil, plants, and animals, (3) the ecology of olfaction as it relates to wildlife habitat selection and predation, and (4) the role of birds and urbanization in the ecology of vector-borne diseases.
