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...

The role of ascorbic acid on discoloration of strawberry juice and concentrate

Creator:: Poei, Metty Soek-Kioen
Abstract:: The purpose of this.investigation was to determine how enzymes and oxygen influence the role ascorbic acid has on pigment degradation and browning during storage for strawberry juice and concentrate. The ascorbic and dehydroascorbic acid content of blanched and unblanched, nitrogen-treated and air-exposed samples of strawberry juice and concentrate was measured...

Relationships between seasonal suspended sediment behavior and reservoir turbidity

Creator:: Conner, Dan Alan
Abstract:: The causes of turbidity in impounded and released reservoir water are studied. Seven Willamette Basin reservoirs are compared to isolate watershed and reservoir characteristics which produce variations in turbidity. Of the seven, Hills Creek Reservoir is examined in detail. Particular features of the basin and impoundment are studied to isolate...

Stability of gravel at artificially created spawning beds in uncontrolled streams

Creator:: Helland-Hansen, Erik Andreas
Abstract:: Twenty-five gabion-type structures across the main stem and tributaries of the Siuslaw River in the Oregon Coastal Range, installed to expand the available spawning area for fish, were investigated for their ability to perform gravel control functions such as trapping bedload carried by the stream or holding gravel placed behind...

Fecundity and longevity in Tribolium castaneum : a selection experiment

Creator:: Treneman, Nancy C.
Abstract:: Recent experimental and theoretical work has examined the possible genetic causes of senescence. These are reviewed, and four types of factors are found to be responsible for the evolution of senescence and age specific fecundity curves: 1. Age specific mortality schedules, 2.Density dependent factors, 3. Density independent factors, 4. Random...

Voluntary environmental programs at an alpine ski area: influence of recreationists' knowledge, motivations, attachment, value orientations, and specialization

Creator:: Little, Christopher M.
Abstract:: Voluntary environmental programs (VEPs) have been created to encourage companies to engage in behaviors that mitigate environmental impacts (e.g., recycling, emissions reduction). Many ski areas participate in the Sustainable Slopes Program, an initiative that promotes VEPs in the ski area industry. Past research has addressed the performance of VEPs in...

Evaluation of meadowfoam (Limnanthes alba) meal as a feedstuff for rabbits, poultry and sheep

Creator:: Throckmorton, John C.
Abstract:: Meadowfoam (Limnanthes alba) is a winter annual oilseed crop native to the Pacific Coast states. Seven experiments were conducted to evaluate extracted meadowfoam meal (MFM) as a feedstuff for poultry, rabbits and sheep. Three experiments were conducted to evaluate MFM as a protein supplement for broiler chicks and weanling rabbits....
