Effect of adult aquatic insect life history on return to Lookout Creek, H. J. Andrews Experimental Forest, Oregon

Creator:: Farrand, Alexander Mark
Abstract:: Aquatic insects that emerge out of streams to mate represent a potential energy flux to terrestrial food webs. The relative success of an individual aquatic adult insect is whether it survives long enough to produce offspring, i.e. mate and return to the stream to oviposit eggs. Some characteristics of the...

Mark-recapture estimates of population parameters for selected species of small mammals

Creator:: Hammond, Ellen L.
Abstract:: I used program CAPTURE to analyze 1,535 data sets for 33 North American species of small mammals for sources of variation in capture probabilities and to characterize species-specific responses to markrecapture trapping. CAPTURE incorporates seven models to account for all possible combinations of heterogeneity (h), behavioral response (b), and time...

Electrofishing mark-recapture and depletion methodologies evoke behavioral and physiological changes in cutthroat trout (Oncorhynchus clarki)

Creator:: Mesa, Matthew G.
Abstract:: We examined the behavioral and physiological responses of wild and hatchery-reared cutthroat trout Oncorhynchus clarki subjected to a single electroshock, electroshock plus marking, and multiple electroshocking in natural and artificial streams. In a natural stream, trout released after capture by electrofishing and marking showed distinct behavioral changes: fish immediately sought...

Morphological changes in introduced eastern cottontails in Oregon

Creator:: Rhodes, Mark Nicolas
Abstract:: Descendants of eastern cottontails from Ohio (Sylvilagns floridanus) introduced in Benton County, Oregon and cottontails from Ohio were sampled and analyzed morphometrically and colorimetrically. In general, Oregon cottontails were smaller and lighter in color than Ohio rabbits. Introgression and interspecific competition with the smaller and darker colored native brush rabbit...

Causes and Consequences of Timing Errors Associated With Global Positioning System Collar Accelerometer Activity Monitors

Creator:: Gaylord, Adam J. and Sanchez, Dana M.
Abstract:: Direct behavioral observations of multiple free-ranging animals over long periods of time and large geographic areas is prohibitively difficult. However, recent improvements in technology, such as Global Positioning System (GPS) collars equipped with motion-sensitive activity monitors, create the potential to remotely monitor animal behavior. Accelerometer-equipped activity monitors quantify animal motion...

Supplemental data to "Estimating the Genetic Diversity of Pacific salmon and trout using Multi-gene eDNA Metabarcoding"

Creator:: Weitemier, Kevin A.
Abstract:: This dataset contains DNA sequence data of Oncorhynchus species, isolated from environmental DNA (eDNA) from Pacific Northwest streams via microfluidic eDNA metabarcoding and high-throughput (Ilummina) sequencing (samples collected from 2017-09-22 to 2017-10-10). It is accompanied by scripts and commands for data analyses including: sequence denoising, calculation of entropy values by...

Identification of optimal broodstock for Pacific Northwest oysters

Creator:: Stick, David A.
Abstract:: The United States Pacific Northwest is well known for its shellfish farming. Historically, commercial harvests were dominated by the native Olympia oyster, Ostrea lurida, but over-exploitation, habitat degradation, and competition and predation by non-native species has drastically depleted their densities and extirpated many local populations. As a result, shellfish aquaculture...

Prey preference of lingcod (Ophiodon elongatus), a top marine predator : implications for ecosystem-based fisheries management

Creator:: Tinus, Craig A.
Abstract:: Many highly exploited ecosystems are managed on the basis of single-species demographic information. This management approach can exacerbate tensions among stakeholders with competing interests who in turn rely on data with notoriously high variance. In this case study, an application of diet and dive survey data was used to describe...

Abundance, movements, and feeding habits of harbor seals, Phoca vitulina, at Netarts and Tillamook Bays, Oregon

Creator:: Brown, Robin F. and Mate, Bruce R.
Abstract:: Patterns of seasonal abundance of harbor seals at Netarts and Tillamook Bays, Oregon, were documented by recording numbers of seals hauling out on tidally exposed sand flats in both bays. Harbor seal abundance at Tillamook Bay peaked during pupping (May-June) and molting (August) periods, while peak abundance at Netarts Bay...

A Meta-Analysis of Lesser Prairie-Chicken Nesting and Brood-Rearing Habitats: Implications for Habitat Management

Creator:: Hagen, Christian A., Grisham, Blacke A., Boal, Clint W., and Haukos, David A.
Abstract:: The distribution and range of lesser prairie-chicken (Tympanuchus pallidicinctus) has been reduced by >90% since European settlement of the Great Plains of North America. Currently, lesser prairie-chickens occupy 3 general vegetation communities: sand sagebrush (Artemisia filifolia), sand shinnery oak (Quercus havardii), and mixed-grass prairies juxtaposed with Conservation Reserve Program grasslands....
