Water samples were collected between June and December 2011 by AndrewMajeske, a student intern working with the Institute forWatershed Studies (IWS) and the Nooksack Salmon Enhancement Association (NSEA). The results from this project were summarized by Majeske et al. (2012). The water quality monitoring was funded for a second year by P4LP, which provided funding for IWS student intern Laura Junge. Additional funding was provided by the City of Bellingham to identify …

Multi-Year Lags Between Forest Browning And Soil Respiration At High Northern Latitudes, Ben Bond-Lamberty, Andrew Godard Bunn, Allison M. Thomson

Environmental Sciences Faculty and Staff Publications

High-latitude northern ecosystems are experiencing rapid climate changes, and represent a large potential climate feedback because of their high soil carbon densities and shifting disturbance regimes. A significant carbon flow from these ecosystems is soil respiration (RS, the flow of carbon dioxide, generated by plant roots and soil fauna, from the soil surface to atmosphere), and any change in the high-latitude carbon cycle might thus be reflected in RSobserved in the field. This study used two variants of a machine-learning algorithm and least squares regression to examine how remotely-sensed canopy greenness (NDVI), climate, and other variables are …

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 …

Numerical Models Of Salt Marsh Evolution: Ecological, Geomorphic, And Climatic Factors, Sergio Fagherazzi, Matthew Lynn Kirwan, Simon Marius Mudd, Glenn R. Guntenspergen, Stijn Temmerman, Andrea D'Alpaos, Johan Van De Koppel, John M. Rybczyk, Enrique Reyes, Christopher B. Craft, Jonathan Clough

Environmental Sciences Faculty and Staff Publications

Salt marshes are delicate landforms at the boundary between the sea and land. These ecosystems support a diverse biota that modifies the erosive characteristics of the substrate and mediates sediment transport processes. Here we present a broad overview of recent numerical models that quantify the formation and evolution of salt marshes under different physical and ecological drivers. In particular, we focus on the coupling between geomorphological and ecological processes and on how these feedbacks are included in predictive models of landform evolution. We describe in detail models that simulate fluxes of water, organic matter, and sediments in salt marshes. The …

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.

Sustainable Landscapes: Evaluating Strategies For Controlling Autumn Olive (Elaeagnus Umbellata) On Reclaimed Surface Mineland At The Wilds Conservation Center In Southeastern Ohio, Shana M. Byrd, Nicole D. Cavender, Corine M. Peugh, Jenise Bauman

College of the Environment on the Peninsulas Publications

Autumn olive (Elaeagnus umbellata) was planted during the reclamation process to reduce erosion and improve nitrogen content of the soil. However, since its establishment, E. umbellata has spread prolifically and control measures are difficult. The primary objective of this case study was to evaluate the effectiveness of various control methods on eradication of E. umbellata in varying degrees of infestation. A two-phase case study was conducted at The Wilds conservation center in Cumberland, OH. Phase 1 began in 2007-2008 to evaluate three treatments in areas with moderate cover (15-30%) of E. umbellata: mechanical removal, foliar herbicide, and dormant stem …

Fostering Ecological Citizenship: The Case Of Environmental Service-Learning In Costa Rica, Jennifer Rebecca Kelly, Troy D. Abel

College of the Environment on the Peninsulas Publications

The intent of this study was to explore how experiential education fosters ecological or environmental citizenship. In this context, we investigated the impact of international environmental service-learning in a college course. Specifically our research question was does environmental service-learning have an effect on ecological citizenship? Using a multimethod approach of both qualitative and quantitative instruments our study drew on 13 participant interviews, 19 student journals and 10 survey responses. Employing variables from the Value-Belief-Norm Theory our findings suggest that environmental service-learning experiences impact both awareness of environmental consequences and personal normative beliefs. We conclude that ecological citizenship was indirectly impacted …

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 …

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 …

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, …
