Multi Scale Habitat Relationships Of Martes Americana In Northern Idaho, U.S.A, Tzeidle N. (Tzeidle Nicole) Wasserman, Samuel A. Cushman, David O. Wallin, Jim Hayden

Environmental Sciences Faculty and Staff Publications

We used bivariate scaling and logistic regression to investigate multiple-scale habitat selection by American marten (Martes americana). Bivariate scaling reveals dramatic differences in the apparent nature and strength of relationships between marten occupancy and a number of habitat variables across a range of spatial scales. These differences include reversals in the direction of an observed association from positive to negative and frequent dramatic changes in the apparent importance of a habitat variable as a predictor of marten occurrence. Logistic regression on the optimally scaled input variables suggests that at the scale of home ranges, marten select landscapes with …

Lake Whatcom Monitoring Project 2010/2011 Report, Robin A. Matthews, Michael Hilles, Joan Vandersypen, Robert J. Mitchell, Geoffrey B. Matthews

Lake Whatcom Annual Reports

This report is part of an on-going series of annual reports and special project reports that document the Lake Whatcom monitoring program. This work is conducted by the Institute for Watershed Studies and other departments at Western Washington University.

The major objective of this program is to provide long-term baseline water quality monitoring in Lake Whatcom and selected tributaries. Each section contains brief explanations about the water quality data, along with discussions of patterns observed in Lake Whatcom.

Macaw Cam: Exploratory Camera Trap Techniques For Monitoring And Conservation Of Scarlet Macaw (Ara Macao) Nests, Derek Schruhl, Tana Beus, Troy D. Abel, Michael J. Medler, Adrian Arce, Kathryn Mork

College of the Environment on the Peninsulas Publications

In this study, we explored new, low-cost camera trap techniques to monitor Scarlet Macaws in one of their last two self-sustaining habitats in Costa Rica. Camera trap monitors have begun to produce new insights in avian research and we use them not only because Macaws are threatened, but their imagery can be used to enhance the public’s understanding of the connections between science and conservation efforts. We mounted camera units on two trees with nesting Macaws in Costa Rica’s Carara National Park and monitored one nest remotely for seven consecutive months.

Ecotopia's Prism, Troy D. Abel

College of the Environment on the Peninsulas Publications

Since 2003, I’ve taken more than 150 students of environmental studies to explore the landscapes, culture and economy of Costa Rica. Costa Rica’s tourism bureau proudly proclaims “no artificial ingredients” to draw visitors from around the world. Situated at the confluence of two oceans and bridging two continents in the tropical latitudes, this small nation hosts some of the greatest concentration of biodiversity anywhere. Costa Rica is about the size of West Virginia, or 0.03% of the world’s surface, yet it holds an estimated 5 percent of the world’s biodiversity. Species from North and South America mixed on this continental …

Education: Participatory Ecological Monitoring And Environmental Education In 2011, Troy D. Abel

College of the Environment on the Peninsulas Publications

In the summer of 2011, faculty from Western Washington University’s (WWU) Huxley College of the Environment implemented a five week field course in Costa Rica exploring Participatory Ecological Monitoring and the pedagogies of Environmental Education. Faculty and students completed observational studies of tree diversity, soil composition, avian bioacoustics, collaborative conservation management, and environmental education. Comparative observations were conducted at biological stations in Carara and Corcovado National Park in collaboration with Park staff. We hypothesized that significant contrasts will occur between Carara’s secondary and Corcovado’s primary forests and their neighboring communities. Our results inform Costa Rican conservation and management strategies as …

Coming Clean And Green: A Geospatial Mapping Tool For Visualizing Industrial Environmental Performance, Jacob Lesser, Troy D. Abel, Mark Stephan

College of the Environment on the Peninsulas Publications

The mapping of environmental data is rapidly expanding as advocates and scholars offer various platforms to display and analyze geographic environmental information.This working paper describes an online web map that displays national data from the Toxic Release Inventory (TRI), Environmental Systems Research Institute’s (ESRI) ArcGIS Server platform, the Environmental Protection Agency’s (EPA) Risk Screening Environmental Indicators (RSEI), and methodologies from Kraft, Stephan, and Abel (2011) to spatially display the environmental performance of more than 17,000 manufacturing facilities.

Large And Small: Conserving Single Large And Several Small, Troy D. Abel

College of the Environment on the Peninsulas Publications

Huxley College of the Environment’s field course on rainforest conservation traces some of its roots to a seminal 1967 publication. MacArthur and Wilson’s The Theory of Island Biogeography presented two fundamental principles. Larger islands support more species than smaller ones and remote islands support fewer species than less remote ones. Moreover, they also established how habitat can be insulated by not only distance between islands, but anything that divides a landscape such as mountains and climate. But the conservation implications of biogeography became dichotomized during the seventies and eighties into a debate between preserving a Single Large section of habitat, …

Five Seasons In Ecotopia: Rainforest Immersion And Conservation Action In Costa Rica, Troy D. Abel

A Collection of Open Access Books and Monographs

This book, Five Seasons in Ecotopia: Rainforest Immersion and Conservation Action in Costa Rica, is an effort to share our perspectives from five years of experience studying and teaching in Costa Rica through the intersections of geography, ecology, and political science. These reflect the dominant pedigrees of more than one-hundred students who annually spent five weeks in Huxley College of the Environment’s RICA program in Costa Rica. The RICA program was designed to foster global ecological citizenship through practices of democratic ecology that activate learner awareness and efficacy among undergraduate participants, Costa Rican students from local schools, and community …
