Age, growth, and diet of fish in the Waldo Lake natural-cultural system

Creator:: Swets, Nicola L.
Abstract:: Waldo Lake, located in the Oregon Cascades, is considered to be one of the most dilute lakes in the world. Even with very low nutrient concentrations and sparse populations of zooplankton, introduced fish in the lake are large in size and in good condition when compared to fish from other...

Lake classification in the glacially influenced landscape of the north Cascade mountains, Washington, USA

Creator:: Lomnicky, Gregg A.
Abstract:: Factors affecting physical, chemical, and biological characteristics of lakes were investigated through the development of a lake-classification system for 162 lakes in North Cascades National Park Service Complex. A conceptual view of lake development and its relationship to the expression of lake and watershed characteristics was derived. Water quality and...

Effects of wildfire on growth and demographics of coastal cutthroat trout in headwater streams

Creator:: Heck, Michael P.
Abstract:: Wildfire is a largely terrestrial perturbation broadly recognized as an agent of disturbance and ecological change in forested biomes. Effects of post-fire conditions on biotic components of aquatic systems have been less well-documented, although hypothetically, the two are strongly connected. In fact, the influence of wildfire may be most profound...

Sediment characteristics and the trophic status of four Oregon lakes

Creator:: Meyerhoff, Roger Dean
Abstract:: There is evidence that recent ecological changes in lakes and their watersheds can be detected from analysis of lake sediments. This study was initiated to correlate changes in some sediment characteristics of four Oregon lakes with past cultural developments of the lakes and their watersheds. The lakes chosen for this...

Comparison of methods to estimate population density of Pacific giant salamanders in small streams of the southern Oregon Cascades

Creator:: Leuthold, Niels C.
Abstract:: I compared hand sampling, two-pass multiple removal sampling, mark-recapture and catchability-based population estimates for the Pacific giant salamander (Dicamptodon tenebrosus) at 22 sites in 11 streams of Cascade Mountains of Oregon. Mark-recapture and catchability-based population estimates were not significantly different (p 0.86). Hand sampling and two-pass multiple removal population estimates...

Patterns of coastal cutthroat trout survival in two headwater stream networks

Creator:: Berger, Aaron M.
Abstract:: Mark-recapture methods were used to examine watershed-scale survival rates of coastal cutthroat trout (Oncorhynchus clarkii clarkii) from two headwater stream networks located in the foothills of the Cascade Mountain Range, Oregon. Differences in survival were explored among spatial (stream segment, stream network [main stem or tributaries], and watershed) and temporal...

Influence of stocking density on grazing beef cattle performance, diet composition foraging efficiency, and diet quality on a late-spring early-summer native bunchgrass prairie

Creator:: Wyffels, Samuel A.
Abstract:: This study evaluated the influence of cattle stocking density on botanical composition of diet, diet preference, and cattle performance on the Zumwalt Prairie in Northeastern Oregon. In each of two years, 192 cow-calf pairs (549.27 kg, BCS = 4.89) and 48 yearling heifers (383.34 kg, BCS = 5.02) were stratified...

Landscape occupancy by free ranging cattle in northeast Oregon

Creator:: Wilson, Kerry D.
Abstract:: Global Positioning System (GPS) and Geographic Information System (GIS) technologies were employed to evaluate cattle occupancy of three landscape attributes on three different grazing allotments administered by the Wallowa Whitman National Forest in Northeast Oregon. Topographic characteristics of slope; 0-4%, 4-12%, 12-35% and >35% were evaluated as well as north...
