People: Ecosystems Landscapes Ecology
Assistant Professor of Aquatic Ecology
The relationship between community structure and ecosystem processes in rivers and streams, and factors which influence this relationship across local, landscape, and regional spatial scales.
Associate Professor of Anthropology
Livelihood decisions and habitats, exploring the dynamics of human subsistence practices, their role in ecosystem function, and their archaeological implications in Australia and Western North America.
Professor of Anthropology
Gender division of labor in hunting and gathering, cooperation, costly signaling, indigenous conservation/land management, and fire ecology, drawing on theory, models, and methods from behavioral ecology and landscape ecology to answer questions about how local social contexts influence economic decision-making and how such decisions impact local ecological communities.
Professor of Soil Microbiology and Biogeochemistry
Compositions and functions of microbiomes in agriculture, ecological restoration, and engineered systems for ecosystem service provision and climate change adaptation
Adjunct Asst. Professor of Wildlife Ecology; Leader, PA Coop. Fish and Wildlife Research Unit
Wildlife ecology, estimation of population parameters, and harvest management of game populations.
Professor of Pedology
Soil formation and biogeochemistry due to land use and ecosystem change; soil and water degradation, and the remediation of soil physical and chemical properties in urban environments.
