The influence of social structure and molecular evolution on genetic diversity in the sperm whale (Physeter macrocephalus)

Creator:: Alexander, Alana
Abstract:: The sperm whale (Physeter macrocephalus) shows some of the most derived characteristics of any mammal: a large body size, large brain, complex social organization and a capacity for deep foraging dives that few other marine mammals can match. Despite a history of exploitation that removed hundreds of thousands of individuals,...

Chemical signaling and pheromone evolution in plethodontid salamanders

Creator:: Palmer, Catherine Anne
Abstract:: My dissertation focuses on the evolutionary forces that have shaped the chemical signaling system of plethodontid salamanders. Pheromones mediate two phases of plethodontid reproduction: mate attraction prior to courtship and female persuasion during courtship. Substrate-borne chemical signals are believed to play an important role in mate attraction for these animals....

Pheromone mechanisms and behavioral strategies for maximizing courtship success in a terrestrial salamander, Plethodon shermani

Creator:: Vaccaro, Elyse A.
Abstract:: Darwin devised the evolutionary theory of sexual selection to account for the manifold extravagances of courtship behaviors and displays. Mating interactions represent a major evolutionary process driving the elaboration, vibrancy, and peculiarity of these courtship traits. For my dissertation research, I strived to elucidate the dynamics that constitute the complex...

Assessing the phosphorus and potassium balances in Oregon's dairies

Creator:: Higgs, Kathryn N.
Abstract:: A field study was conducted to assess phosphorus (P) and potassium (K) concentrations of both lactating and dry cow diets on Oregon's dairies. Thirty-seven dairy farms, located in western Oregon, were grouped according to geographic region, valley (V) or coast (C), and herd size, small (S) or large (L). Farms...

Feed management : a tool for balancing nutrients on dairies and other livestock operations

Creator:: Gamroth, Michael J., Downing, Troy (Troy Woerner), French, Patrick D., 1969-, and Oregon State University. Extension Service
Abstract:: Many studies have shown that dairies consistently overfeed nutrients such as phosphorus (P) and potassium (K). This practice is expensive and potentially damaging to the environment and to animal health. This publication suggests ways to improve feed management and thus avoid overfeeding P and K. Proper ration balancing is good...

Movement and space use by the green hermit (Phaethornis guy) in a fragmented landscape in Costa Rica

Creator:: Volpe, Noelia L.
Abstract:: Human activities have altered Earth’s ecosystems. Most biomes have experienced a 20-50% conversion to human use. Loss of habitat has obvious effects on the persistence of species. Fragmentation, however, may also negatively affect biodiversity for those species that exhibit behavioral responses to changes in habitat configuration. Such behavioral changes include...

Regions to streams : spatial and temporal variation in stream occupancy patterns of coho salmon (Oncorhynchus kisutch) on the Oregon coast

Creator:: Flitcroft, Rebecca L.
Abstract:: Aquatic ecological investigation is expanding to encompass considerations of multiple scales across large landscapes. Much of the analysis included in this work focuses specifically on coho salmon (Oncorhynchus kisutch) in multiple subbasins on the Oregon coast. Coho salmon were chosen for an investigation of spatial scales, network connections, and life...

The Effect of Group Size on Individual Roles and the Potential for Cooperation in Group Bubble-net Feeding Humpback Whales (Megaptera novaeangliae)

Creator:: Mastick, Natalie
Abstract:: Group foraging is observed in many species as a means to increase the ability of members of the group to find and exploit patchy prey. Group foraging can be exhibited in a number of different contexts based on the relationships between the participants, including by-product mutualism. One variant of by-product...

Growth pathways in feline oral squamous cell carcinoma

Creator:: Harris, Krystal, L.
Abstract:: Background Bcl11b, previously CTIP2, is a zinc finger nuclear transcription factor involved in the development of keratinocytes, teeth, T lymphocytes, and nervous tissue. Expression of Bcl11b has been reported in human head and neck squamous cell carcinoma (HNSCC) and increased expression correlates with poorly differentiated tumors. This study aimed to...

Alpha-tocopherol is a potential diagnostic indicator of metabolic diseases in early lactation dairy cows, α-tocopherol is a potential diagnostic indicator of metabolic diseases in early lactation dairy cows

Creator:: Qu, Yang
Abstract:: Milk fever (MF), retained placenta (RP), and left displaced abomasum (LDA) are three common and costly metabolic diseases in cows during the first days of lactation. Some studies suggest that circulating concentrations of α-tocopherol (ATOC) are decreased by these three diseases. It is, however, unknown if and how long lower...
