Butterflies of the H.J. Andrews Experimental Forest : biological inventory and ecological analysis

Creator:: Ross, Dana N. R.
Abstract:: A biological inventory of the butterflies of the H. J. Andrews Experimental Forest [HJA] in Linn/Lane County, Oregon was conducted during 1994 and 1995. It was the first comprehensive survey of HJA butterflies for the site and serves as a baseline for future butterfly research. A detailed ecological account is...

Bioenergetic evaluation of diel vertical migration by bull trout

Creator:: Eckmann, Madeleine
Abstract:: I evaluated hypotheses related to growth as a driver of depth use and diel vertical migration by bull trout (Salvelinus confluentus) in a thermally stratified reservoir. I applied a bioenergetic model to evaluate growth of bull trout in relation to potential patterns of diel depth use by bull trout in...

African American Males' Perceptions of Success while Attending Community College

Creator:: Emerson, Dana M.
Abstract:: Background: African American males' experience in higher education is often categorized with negative terminology that does not reflect notions of success. Most research addressing the success of African American males in higher education illuminates factors that impede access to success and is often situated in university settings. Very little research...

Phytoplankton of an ice-edge bloom in the Ross Sea, with special reference to the elemental composition of Antarctic diatoms

Creator:: Carbonell, Maria Consuelo
Abstract:: A phytoplankton bloom dominated by the pennate diatom Nitzschia curta (Van Heurck) Hasle was observed during January-February 1983 at a receding ice-edge in the Western Ross Sea, Antarctica. The core of the bloom was found between 100-150 Km from the ice-edge. Nitzschia curta cell densities up to 22 x 10⁶...

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...

Vegetation and Small Mammal Responses to Western Juniper (Juniperus occidentalis) Control in Eastern Oregon

Creator:: Morozumi, Corinne N.
Abstract:: Shrub-steppe ecosystems of western North America provide habitat for many wildlife species, are important components of public and private rangelands, and offer recreational opportunities for millions of people. They are some of the most vulnerable ecosystems in the United States and have been altered by human activities such as livestock...

Assessing variation in coyote (Canis latrans) diet across three sagebrush steppe sites with different levels of juniper encroachment

Creator:: Kendall, Zachary D.
Abstract:: Juniper (Juniperus spp.) encroachment into the sagebrush steppe ecoregion is one of the main causes of sagebrush degradation and can alter the understory vegetative community by outcompeting native shrubs and grasses, which reduces the available forage and cover for small mammals. Coyotes (Canis latrans) are generalist, omnivorous predators in the...

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...
