The Distribution And Reproductive Success Of The Western Snowy Plover Along The Oregon Coast - 2009, David J. Lauten, Kathleen J. Castelein, J. Daniel Farrar, Hendrik G. Herlyn, Eleanor P. Gaines

Institute for Natural Resources Publications

From 3 April – 23 September 2009 we monitored the distribution, abundance and productivity of the federally Threatened Western Snowy Plover (Charadrius alexandrinus nivosus) along the Oregon coast. From north to south, we surveyed and monitored plover activity at Sutton Beach, Siltcoos River estuary, the Dunes Overlook, North Tahkenitch Creek, Tenmile Creek, Coos Bay North Spit, Bandon Beach, New River, and Floras Lake. Our objectives for the Oregon coastal population in 2009 were to: 1) estimate the size of the adult Snowy Plover population, 2) locate plover nests, 3) continue selective use of mini-exclosures (MEs) to protect nests …

Similarity Of Nutrient Uptake And Root Dimensions Of Engelmann Spruce And Subalpine Fir At Two Contrasting Sites In Colorado, Melissa S. Lucash, Ruth D. Yanai, Karis J. Mcfarlane, Sarah E. Kulpa, Dustin M. Wood

Environmental Science and Management Faculty Publications and Presentations

Nutrient uptake capacity is an important parameter in modeling nutrient uptake by plants. Researchers commonly assume that uptake capacity measured for a species can be used across sites. We tested this assumption by measuring the nutrient uptake capacity of intact roots of Engelmann spruce (Picea engelmanni Parry) and subalpine fir (Abies lasiocarpa (Hook.) Nutt.) at Loch Vale Watershed and Fraser Experimental Forest in the Rocky Mountains of central Colorado. Roots still attached to the tree were exposed to one of three concentrations of nutrient solutions for time periods ranging from 1 to 96h, and solutions were analyzed for ammonium, …

How Does A Visual Monitoring System Foster Sustainable Behavior?, Melissa Haeffner, Federico Casalegno

Environmental Science and Management Faculty Publications and Presentations

Americans spend upwards of 90% of each day in buildings that account for two-thirds of electricity usage. Because the supply of smart buildings will take time to catch up with demand, efforts are sought to develop informed and educated people to live and work in these “dumb” buildings. Additionally, energy efficiency alone may be inadequate to achieve major reduction in carbon emissions (Darby, 2006). Finding ways to intentionally change the lifestyle behavior in a household should have significant implications in reducing environmental impacts as fossil energy use in resident homes is directly related to the exploitation of natural resources and …

Climate Justice: Towards A Proactive Response To Social Inequities, Vivek Shandas

Institute for Sustainable Solutions Publications and Presentations

Discussions about climate change have taken center stage. Claims of 'carbon neutral', and strategies for calculating and mitigating green house gas emissions (GHGs) have become common place from Beaverton to Bali. The discourse on climate change, however, remains largely an environmental one, with increasingly precise definitions of parts per million, downscaling climate models, and regional assessments for reducing carbon dioxide (CO2) emissions. These discussions are essential for understanding connections between local sources of GHGs and global consequences of our actions. But health and equity are equally critical dimensions of climate change, although these dimensions have had only limited investigation. Regional …

Increasing The Reliability Of Ecological Models Using Modern Software Engineering Techniques, Robert M. Scheller, Brian R. Sturtevant, Eric J. Gustafson, Brendan C. Ward, David J. Mladenoff

Environmental Science and Management Faculty Publications and Presentations

Modern software development techniques are largely unknown to ecologists. Typically, ecological models and other software tools are developed for limited research purposes, and additional capabilities are added later, usually in an ad hoc manner. Modern software engineering techniques can substantially increase scientific rigor and confidence in ecological models and tools. These techniques have the potential to transform how ecological software is conceived and developed, improve precision, reduce errors, and increase scientific credibility. We describe our re-engineering of the forest landscape model LANDIS (LANdscape DIsturbance and Succession) to illustrate the advantages of using common software engineering practices.

Development Of An Ambient Pressure Laser-Induced Fluorescence Instrument For Nitrogen Dioxide, Jeremy Parra, Linda Acha George

Environmental Science and Management Faculty Publications and Presentations

Concerns about the health effects of nitrogen dioxide (NO₂) and its role in forming deleterious atmospheric species have made it desirable to have low-cost, sensitive ambient measurements of NO₂. We have developed a continuous-wave laser-diode laser-induced fluorescence (LIF) system for NO₂ that operates at ambient pressure, thereby eliminating the need for an expensive pumping system. The current prototype system has achieved sensitivity several orders of magnitude beyond previous efforts at ambient pressure (limit of detection of 2 ppb, 60 s averaging time). Ambient measurements of NO₂ were made in Portland, Oregon using both the standard NO₂ chemiluminescence method and the …

Mangrove-Exported Nutrient Incorporation By Sessile Coral Reef Invertebrates, Elise F. Granek, Jana E. Compton, Donald L. Phillips

Environmental Science and Management Faculty Publications and Presentations

Coastal mangrove forests were historically considered as a source of organic matter (OM) for adjacent marine systems due to high net primary production; yet recent research suggesting little uptake through the food web because of low nutritional quality, challenges the concept of trophic linkage between mangrove forests and coral reefs. To examine the importance of mangrove forests to coral reef nutrient availability, we examined sessile reef-forming invertebrate consumers including hard corals, sponges, a bivalve mollusc, polychaete annelid and tunicate, and potential sources of OM (decaying mangrove leaves, microalgae, macroalgae, and seagrass) in Bocas del Toro, Panama. Using stable isotope analyses …
