The influence of forest management on headwater stream amphibians at multiple spatial scales

Creator:: Stoddard, Margo A.
Abstract:: To effectively manage for biodiversity at broad, ecosystem scales, the influences of habitat structure at multiple spatial scales on vertebrate species must be understood. There are few studies on the broad-scale habitat requirements of stream amphibians despite their importance in streams in forest ecosystems in the Pacific Northwest (PNW) as...

Terrestrial amphibian abundance and species richness in headwater riparian buffer strips, Oregon Coast Range

Creator:: Vesely, David G. (David Gordon), 1954-
Abstract:: I examined the abundance and habitat associations of terrestrial amphibian species and the species richness of terrestrial amphibian communities in riparian buffer strips, clearcuts, and unmanaged riparian forests. The study was conducted in the western hemlock (Tsuga heteropliylla) vegetation zone of the northern and central Oregon Coast Range. Data were...

Watershed-level patterns among stream amphibians in the Blue River watershed, West-Central Cascades of Oregon

Creator:: Hunter, Matthew G.
Abstract:: Most recent research on stream amphibians in the Pacific Northwest has focused on associations with reach-level or stand-level environmental features. Little is known about landscape-level distributions of these species or landscape-level aspects of their life-histories. I used a watershed-wide sample and logistic regression to develop models and maps of probability...

Habitat associations of small mammals and amphibians in the central Oregon Coast Range

Creator:: Martin, Karl J.
Abstract:: One of the goals of ecosystem management is to integrate management of many species and processes across a range of temporal and spatial scales. I investigated the relationship between small mammals and amphibians at 3 spatial scales. My objective was to identify, habitat associations of forest floor vertebrates at the...

Habitat classification and characteristics of small mammal and amphibian communities in beaver-pond habitats of the Oregon Coast Range

Creator:: Suzuki, Nobuya
Abstract:: During 1988-1989, stream habitat variables were compared between beaver-dam sites and unoccupied-stream sites to identify variables that may have been important for beaver (Castor canadensis) in selecting dam sites in the streams of the Drift Creek basin, Lincoln County, Oregon. Increasing valley floor width and grass/sedge cover and decreasing stream...

Fish and amphibian use of intermittent streams within the upper Willamette Basin, Oregon

Creator:: Colvin, Randall William
Abstract:: In the fall through spring of 2002/03 and 2003/04, the composition of fish and amphibian communities were examined in intermittent streams in the upper Willamette river basin in western Oregon. I recorded standard aquatic habitat variables and water nutrient concentrations (nitrate and phosphate) and correlated them with fish and amphibian...

Invasive bullfrog use of novel ephemeral habitats in the Pacific Northwest

Creator:: Cook, Megan Tetsuko
Abstract:: Invasive species are a major threat to global biodiversity. Understanding the mechanisms underlying successful invasions is imperative for developing effective management strategies. Plasticity in physiological, morphological, and behavioral traits could be an indicator of invasion potential in non-native species. The invasive American bullfrog (Lithobates catesbeianus) has recently been observed breeding...

Small-mammal herpetofauna abundance in riparian and upslope areas of five forest conditions

Creator:: Gomez, Douglas M.
Abstract:: I compared species composition and relative abundance of'small mammals and herpetofauna between riparian and upslope habitats among 5 forest types. Riparian- and upslope- associated species were identified based on capture frequency. Small mammal species richness was similar between stream and upslope habitats and among the 5 forest types. There were...

Multiple stressors and amphibian population declines

Creator:: Hatch, Audrey C.
Abstract:: In the past decade, declines in amphibian populations have captured scientific and popular interest. The causes of the declines are likely to be complex and involve interactions between several environmental stressors. Using multifactorial experiments, I investigated the combined effects of several anthropogenic stressors on developing amphibians in Oregon, USA. In...
