Aquatic food web responses to patchy shading along forested headwater streams

Creator:: Heaston, Emily
Abstract:: In small forested streams, changes in age and structure of riparian vegetation covering the stream have been shown to directly influence the amount of light reaching the stream benthos. Light has the potential to impact in-stream resources that support secondary production through constraints on primary productivity. The influence of landscape...

Occurrence of beaver (Castor canadensis) in volcanically disturbed lentic habitat

Creator:: Smith, Sierra L.
Abstract:: This study investigates the occurrence of beaver (Castor canadensis) in lentic habitat (lakes and ponds) near Mount St. Helens in Washington, 40 years after the 1980 eruption. At the coarse spatial scale, I surveyed lakes for sign of beaver establishment (lodge or den) across multiple volcanic disturbance zones. At a...

Experiments and Observations on How Changes in Riparian Forests Affect Light and Stream Ecosystems

Creator:: Swartz, Allison G.
Abstract:: Riparian zones are ecotones between terrestrial and aquatic ecosystems. Processes in streams are strongly influenced by riparian forest communities, age, stage and structure. Temperate forests across much of North America, including riparian areas, are recovering from historic land clearing with many stands in the stem-exclusion phase of development in which...

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,...

Bottom-up Drivers of Primary Producers and Predator Populations in Oregon Streams

Creator:: Kaylor, Matthew J.
Abstract:: Humans have drastically altered the physical habitat and food web structure of stream ecosystems. Two major impacts humans have had on Pacific Northwest streams are modification of streamside forests (as a result of agriculture, land development, and timber harvest), and declines in the return of wild anadromous salmon to headwater...

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...

Resource Selection and Space Use of Western Long-eared Myotis (Myotis evotis) in a Western Juniper (Juniperus occidentalis) Woodland of Central Oregon

Creator:: Anthony, Christopher R.
Abstract:: Identifying habitat and spatial requirements of wildlife species across multiple spatial scales is a challenging, yet crucial component of wildlife management. Habitat use of bats is particularly difficult to study, and managing habitat to conserve bats is especially challenging because bats are highly vagile organisms that exploit several different types...

Truth to Nature: The Art and Ecology of Hudson River School Painting

Creator:: Loeb, Harper
Abstract:: Beginning with the inception of American art history as a formal discipline in the 1940s, the dominant mode of interpreting nineteenth-century American landscape painting has been to view aspects of the landscape as symbols for grand cultural, religious, national, and moral narratives. While this method of interpretation highlights some key...

A Novel Approach to Process-based River Restoration in Oregon : Practitioners’ Perspectives, and Effects on In-stream Wood

Creator:: Bianco, Stephanie R.
Abstract:: The widespread fragmentation, channelization, and simplification of river ecosystems has had acute environmental impacts, including degradation of water quality and habitat and biodiversity loss (Vörösmarty et al., 2010). These concerns have incited an increased focus on reestablishing ecological and hydrogeomorphological functions and improving habitat that has been lost in riverine...

The Effects of Vitamin E on the Lifespan of Caenorhabditis elegans Strains with Mitochondrial Mutations

Creator:: Kusuma, Danika N.
Abstract:: Although assays have been done on the effects of vitamin E alpha-tocopherol (ɑ-tocopherol) on the lifespan of wildtype C. elegans, none have been done on the effects of the vitamin on mutant strains with mitochondrial mutations. By using a mev-1 genetic mutant strain of C. elegans with higher levels of...
