Stream Temperature and Autotrophic Responses to Riparian Canopy Gaps Over Forested Headwater Streams

Creator:: Swartz, Allison
Abstract:: Across much of North America, legacies of historic and contemporary timber harvest have created a landscape dominated by regenerating forest stands in the early to middle stages of development. Most streamside forests are currently in the stem-exclusion phase of stand development and these closed canopies shade the forest understory and...

Cloud shading and fog drip influence the metabolism of a coastal pine ecosystem

Creator:: Carbone, Mariah S., Williams, A. Park, Ambrose, Anthony R., Boot, Claudia M., Bradley, Eliza S., Dawson, Todd E., Schaeffer, Sean M., Schimel, Joshua P., and Still, Christopher J.
Abstract:: Assessing the ecological importance of clouds has substantial implications for our basic understanding of ecosystems and for predicting how they will respond to a changing climate. This study was conducted in a coastal Bishop pine forest ecosystem that experiences regular cycles of stratus cloud cover and inundation in summer. Our...

Exploring the phylogenetic affiliations and the trophic mode of Sedecula pulvinata (Sedeculaceae)

Creator:: Trappe, Matthew J., Smith, Matthew E., and Hobbie, Erik A.
Abstract:: Sedecula is a monotypic genus of hypogeous fungi that is rare and endemic to dry conifer forests of the western United States. The only known species, Sedecula pulvinata, was described in 1941 and its taxonomic placement and trophic status have remained uncertain ever since. Here we employ isotopic and molecular...

Perceptions of protection : coastal resident cognitions concerning new marine reserves in Oregon

Creator:: Perry, Elizabeth E.
Abstract:: Protected area creation, including creation of marine reserves (MRs), is increasingly molded by ecosystem based management (EBM) that integrates biological and social information in the pre and post establishment phases. Collecting social data from large and representative samples of the public (as opposed to other stakeholder groups) before establishing a...

Calcium-oxalate in sites of contrasting nutrient status in the Coast Range of Oregon

Creator:: Dauer, Jenny M.
Abstract:: Calcium (Ca) is an essential macronutrient that is increasingly recognized as a biogeochemical factor that influences ecosystem structure and function. Progress in understanding the sustainability of ecosystem Ca supply has been hampered by a lack of information on the various forms and pools of Ca in forest ecosystems. In particular,...

The Effects of Road Noise on Pacific Chorus Frog Communication

Creator:: Nelson, Danielle V.
Abstract:: Amphibians are experiencing global population declines and are one of the most threatened groups of vertebrates. This can be attributed to multiple environmental stressors such as habitat loss, disease, invasive species, and climate change. For vocal amphibian species, loss of acoustic habitat due to anthropogenic noise may be yet another...

Distinguishing biological and physical controls on soil respiration

Creator:: Phillips, Claire L.
Abstract:: Soil respiration, or the combined CO₂ emissions from roots and soil microorganisms, constitutes one of the largest losses of carbon (C) from terrestrial ecosystems. The major drivers of soil respiration, which include soil moisture, temperature, and substrate quality, have been known for some time. Nevertheless, correlations between these drivers and...

Wild Waters : Perspectives on Oregon’s Marine Reserves as Marine Wilderness Areas

Creator:: Johnston, Jennifer R.
Abstract:: Designation of areas as marine wilderness has been proposed as a strategy for managing the increasing threats facing the world’s oceans. Although social factors influence marine protected area success, the human dimensions of marine wilderness remain minimally explored. This thesis examines views of marine wilderness expressed by a representative sample...

A Review and Recommendations for Assessing Floodplain Vegetation Recovery Following Stage 0 and Beaver Dam Analog Restorations in the Pacific Northwest

Creator:: Colley, Lara K. M.
Abstract:: Floodplains are a significant and increasingly threatened ecosystem. As restoration projects are implemented more frequently in degraded floodplains, novel methods are emerging with a focus on restoring critical processes in which vegetation plays a key role. The purpose of this paper is two-fold: 1) to develop expectations for vegetation response,...

Can Pollination Networks Withstand Species Loss? An Examination of Plant–Hummingbird Interactions and Their Responses to Experimental Removal of a Flowering Plant Species

Creator:: Leimberger, Kara G.
Abstract:: Global environmental change is causing local extinctions of species. When species depend on one another, as in the mutualistic relationship between plants and pollinators, loss of one interaction partner may cause cascading effects within the community – such as additional extinctions and reduced pollination services. Network theory provides a way...
