Creator:: Tsuchihashi, Natsumi
Abstract:: Sociality relies upon mechanisms that permit group living through a balance of costs and benefits. However, it is not fully known how specific social contexts influence behavioral and physiological outcomes, and more broadly, how responses to social situations contribute to social organization. A recent experiment investigating the relationship between social...

Abstract:: Red tree voles (Arborimus longicaudus) are a unique species of Arvicoline rodent found in western Oregon and northwest California. Their preferred habitat is mature and old-growth coniferous forest dominated by Douglas-fir (Pseudotsuga menziesii).

Factors Affecting Histologic Tumor Free Margins in Widely Excised Feline Injection Site Sarcomas

Creator:: Terry, Jesse L.
Abstract:: Feline injection site sarcomas (FISS) are frequently encountered cutaneous and subcutaneous neoplasms of cats. Significant patient morbidity is related to the invasiveness these tumors display, typically requiring extensive local excision or amputation. As with many veterinary tumors, survival time and tumor recurrence for FISS is highly influenced by histologic margin...

Effects of prostaglandin F2alpha on neutrophil populations, uterine health and reproductive performance in dairy cows, Effects of prostaglandin F₂α on neutrophil populations, uterine health and reproductive performance in dairy cows

Creator:: Lulay, Adrienne McCracken
Abstract:: Incidences of uterine infections in dairy cattle are high between parturition and Day 21 postpartum. Dairy cows with uterine infections are at risk for prolonged periods of days open and multiple services before becoming pregnant. Neutrophils are the first wave of immune system defense against uterine contamination. Neutrophil function seems...

Giant gartersnake spatial ecology in agricultural and constructed wetlands

Creator:: Valcarcel, Patricia M.
Abstract:: The spatial ecology of a species is a vital component of informed management and restoration plans, yet little is known about how animals use restored or constructed habitat. We assessed home ranges, core areas, and habitat selection of the federally threatened Giant Gartersnake (Thamnophis gigas) using rice agricultural habitat and...

Foraging ecology of barred owls where they are outcompeting the threatened northern spotted owl

Creator:: Baumbusch, Ryan C.
Abstract:: Following European-American colonization of North America and associated landscape changes, barred owls (Strix varia) underwent a dramatic expansion of their historical range. The barred owl expanded across the previously tree-less Great Plains that had limited their distribution, and into the forests along the west coast. In these western forests they...

Effects of Feeding OmniGen-AF® on Superovulatory Response in Donor Beef Cows

Creator:: Snider, Alexandria P.
Abstract:: One assisted reproductive tool used to propagate highly desirable genetics from elite sire and dam matings is embryo transfer. Superovulation is the first part of the overall protocol and it is a required yet costly and biologically stressful procedure in cattle embryo transfer. The process of superovulation results in high...

Pheromone Variation in Plethodontid Salamanders

Creator:: Chouinard, Adam J.
Abstract:: Plethodontid salamanders have served as an informative vertebrate system for studying the role of chemical signals in facilitating social and reproductive behaviors. Individuals produce complex mixtures of chemicals from multiple glandular regions. In total, these secretions convey a wide variety of information, and are important for numerous inter- and intraspecific...
