Weight watching: Morphometric indices of ontogenetic and reproductive stages in Weddell seals

Creator:: Monnin, Mee-ya A.
Abstract:: We investigated ontogenetic changes in body morphology of Weddell seals (Leptonychotes weddellii) using three three-dimensional (3D) photogrammetry, to estimate surface areas and body volumes for 42 Weddell seals. We sampled ten weaned pups, twelve juveniles (age one or two years), 11 non-breeding adult females, and 9 adult females who had...

Variation of the Trowbridge's shrew (Sorex trowbridgii) diet across forest types in the Oregon Cascades

Creator:: Yates, Margaret E.
Abstract:: Investigating the insectivorous diet of the Trowbridge’s shrew (Sorex trowbridgii) across forest types can illustrate how forest management affects biotic communities. I used DNA metabarcoding methods with ANML primers to identify stomach and intestines contents from shrews caught in pitfall traps in the HJ Andrews Experimental Forest (HJA) and Willamette...

Using quadrats and GPS to assess the abundance of rodent holes in different habitats

Creator:: Dally, Morgan E.
Abstract:: 2018 Library Undergraduate Research Awards nomination materials, reflective learning essay, and research paper. In this study, pocket gopher and gray-tailed vole holes and hills were counted within four distinct habitats using quadrats and a gridding method over a period of five field days. The study was conducted to determine which...

Underwater Camera Systems : A DIY design for field research in freshwater systems

Creator:: Zamarripa, Emily
Abstract:: The ability to observe species in their natural setting using remote cameras is an increasingly important tool for in-field research. Remote cameras for terrestrial studies are inexpensive and widely available, but there are few comparable options for researching aquatic habitats. For this study, a do it yourself (DIY) underwater camera...

The Role of Southern Oregon's Coastal Islands in Prehistoric Subsistence

Creator:: Gard, Howard A.
Abstract:: The portion of the Oregon coast extending from Cape Blanco south into California has long been recognized as a distinct physiographic region, with probable ramifications for prehistoric subsistence and settlement patterns. Several researchers have proposed models outlining a greater reliance upon marine/littoral resources among groups within this region, while more...

The Impact of Income Generating Programs at Tarangire National Park, Tanzania

Creator:: McDowell, Dylan
Abstract:: The newest pilot project at Tarangire National Park (TAR) is Income Generating Programs (IGP) where community groups organize themselves around an activity that earns income. TAR initiated the project by paying for ten members from each of the three existing community groups on the park’s northern end and fifteen members...

The Identification of Early Prehistoric Settlement Patterns Along the Coast of Southwest Oregon : A Survey Based Upon Amateur Artifact Collections

Creator:: Pullen, Reginald John
Abstract:: Surveys of amateur artifact collections in southwest Oregon indicate that traditional settlement pattern models for this region may be in error. Based on the distribution of major styles of projectile points, at least two distinct periods of occupation are definable. The Early period is tentatively dated between 1000 B.C. and...

The effects of x-irradiation, diethylstilbestrol, and size at time of release on the early sexual maturation of coho salmon Oncorhynchus kisutch

Creator:: Lorz, Harold W.
Abstract:: Precocious male coho are of limited economic value and control of their numbers returning to the hatchery or the increased survival of full-sized adults would be beneficial. Factors influencing early sexual maturation and attempts to suppress this maturation of males through the incorporation of a hormone in the diet, treatment...

The Effects of Tank Structure and Egg Size on the Production of Wild Steelhead (Oncorhynchus mykiss) Surrogate Fish

Creator:: Self, Katharine E.
Abstract:: One of the biggest hurdles for a juvenile salmonid (Oncorhynchus mykiss) is migrating downstream from freshwater spawning grounds to the ocean. Juveniles from wild broodstock were reared from the South Santiam River for more than 1 year at the Oregon Hatchery Research Center (OHRC) in Alsea, OR. The fish were...

The effects of acclimation and surface access on the resistance of fish to hypoxic stress

Creator:: Wirosoebroto-Hartadi, Retno Widaningroem
Abstract:: Rainbow trout (Salmo gairdneri) and bluegill (Lepomis macrochirus) were exposed to flows of water containing low DO concentrations produced by bubbling nitrogen through the water. Abrupt exposure of fish to critical DO concentrations (The standard dose response) and by a more gradual changing of DO levels (The "stepdown" approach) were...
