Juanita Sundberg

Juanita Sundberg

University of British Columbia

Juanita Sundberg is an Assistant Professor in the University of British Columbia Geography Department. She brings the insights of feminist political ecology and the sensibilities of an ethnographer to bear on nature conservation, border security, and militarization. One of Juanita's current projects examines the environmental dimensions of United States’ border security policies in the United States-Mexico borderlands, with a specific focus on protected areas like national wildlife refuges.

Columba Gonzales-Duarte

Columba Gonzalez-Duarte

Mount St. Vincent University

Columba Gonzalez-Duarte is a sociocultural anthropologist interested in human-nature relations in North America. For my doctoral research, I explored how different Canada, Mexico, and the United States human communities engage with the at-risk monarch butterfly migration. My current work connects monarch butterflies' decline with other social and ecological problems that North Americans face—from food production to structural violence and climate change. In my research, I use the tools and theoretical propositions of anthropology to achieve eco-social justice.

University of Natural Resources & Life Sciences, Vienna

Dr. Brady Mattsson is a senior scientist with the Institute of Wildlife Biology and Game Management at the University of Natural Resources and Life Sciences, Vienna.  He develops and tests modeling approaches to answer questions in ecology and to inform sustainable management of wide-ranging birds and mammals.  His projects span regional to continental scales, including the integration across scales. These are collaborative efforts that integrate fields of population and community ecology, economics, mathematics, and decision science. Focal systems include northern pintails in North America and large mammals in the Alps.

Gary McCracken

Gary McCracken

University of Tennessee

Gary McCracken is a professor of Ecology & Evolutionary Biology at the University of Tennessee in Knoxville. His research concerns the distribution of animals in space, their behavior and interactions, and resulting impacts on genetic population structure. Currently, these organisms are bats, insects, and fungal and viral pathogens. The projects in his lab involve field studies combined with molecular assays, and ongoing collaboration with The Institute for Ecological Modeling at UTK to better inform data collection and to provide predictive analysis and interpretation.

Darius Semmens joined the USGS Rocky Mountain Geographic Science Center in 2008 as a research physical scientist. His current research interests include the development of new methods and tools for the assessment and valuation of ecosystem goods and services - the specific benefits that we derive from nature. More specifically, his work involves developing methods and tools that can account for the spatial and temporal dynamics of service production and incorporate that into more rigorous analyses of the tradeoffs associated with landscape management.
