United States Department of Agriculture Wildlife Services: Staff Publications

The coqui frog (Eleutherodactylus coqui) was introduced to the island of Hawai’i in the 1980s and has spread across much of the island. Concern remains that this frog will continue to expand its range and invade higher elevation habitats where much of the island’s endemic species are found. We determined whether coqui thermal tolerance and physiology change along Hawai’i’s elevational gradients. We measured physiological responses using a short-term experiment to determine baseline tolerance and physiology by elevation, and a long-term experiment to determine the coqui’s ability to acclimate to different temperatures. We collected frogs from low, medium, and …

Temporal, Phenotypic, And Quantitative Characterization Of Thyroid Infiltrating Mononuclear Cells During Development Of Spontaneous Autoimmune Thyroiditis In Obese Strain Chickens, Katelyn M. Clark, Chrysta N. Beck, Gisela F. Erf

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The Obese strain (OS) of chickens spontaneously develops autoimmune thyroiditis (SAT) and is a well-established biomedical model for Hashimoto’s thyroiditis in humans. Both conditions are characterized by the infiltration of thyroid glands with mononuclear immune cells resulting in the destruction of thyroid tissue and impairment of the thyroid’s endocrinological functions. Past studies described immune cell infiltration in thyroids of the OS chickens, but the time-course, cell composition, and relative amounts of the various immune cells infiltrating the thyroids have not been well defined. In this project, frozen and stored thyroid glands that were previously collected at 1, 4, 7, 14, …

The Importance Of Shape Analysis Of The First Upper Molar In The Separation Of Two Subspecies Of The Hazel Dormouse (Muscardinus Avellanarius (Linnaeus, 1758)) In Northern Anatolia, Güli̇z Yavuz, Hati̇ce Mutlu Eyi̇son, Erkut Kivanç, Engi̇n Selvi̇, Nuri̇ Yi̇ği̇t, Ercüment Çolak

Turkish Journal of Zoology

Morphological features are important for intraspecific and interspecific variation. Teeth are important taxonomical characteristics because they can differ according to diet. Shape analysis of the first upper molar (M1) was used to determine geographical variations and effects of ecological changes on the population structure of Hazel dormice (Muscardinus avellanarius) living in Turkey. Both outline and landmark analysis, as well as a canonical variates analysis, showed significant differences in teeth shape between populations. With this technique, we separated out two subspecies: M. a. trapezius and M. a. abanticus.

Reflections On A Career Unplanned, Robert A. Glazer

Gulf and Caribbean Research

Sometimes life takes unexpected turns. I never planned to be a marine biologist; yet, after a long and unpredictable journey, that’s exactly where I found myself. After obtaining my B.S. in Fishery Biology from Colorado State University, I found myself meandering from job to job like a golden retriever following some vague scent. At first, I was hired by the Wyoming Game and Fish Department to work seasonally in Grand Teton National Park on the freshwater trout fisheries. Soon thereafter, I found myself cultivating oysters, clams, and other shellfish in California. The skills I developed there as an algologist led …

Addressing Soil Carbon Sequestration Response From Multispecies Dairy Forage Systems And Modeling Rangeland Beef Cow Dry Matter Intake Using Precision Enteric Emissions Measurements, Lillian J. Mcfadden

Electronic Theses and Dissertations

Regenerative agriculture is a pressing matter for the dairy industry to address cropland sustainability and carbon sequestration. One regenerative management practice that has been identified to help with row crop sustainability for key metrics like soil organic carbon (SOC) is complex covers. When producers use complex covers one of the main challenges is that it takes time to detect a change in SOC. However, simulation models are a tool that can be used to help determine if a regenerative practice is a strategy that gives the best results (i.e., increased SOC) while aligning with long-term production goals. Therefore, our objectives …

Carnivore And Ungulate Occurrence In A Fire-Prone Region, Sara J. Moriarty-Graves

Cal Poly Humboldt theses and projects

Increasing fire size and severity in the western United States causes changes to ecosystems, species’ habitat use, and interspecific interactions. Wide-ranging carnivore and ungulate mammalian species and their interactions may be influenced by an increase in fire activity in northern California. Depending on the fire characteristics, ungulates may benefit from burned habitat due to an increase in forage availability, while carnivore species may be differentially impacted, but ultimately driven by bottom-up processes from a shift in prey availability. I used a three-step approach to estimate the single-species occupancy of four large mammal species: mountain lion (Puma concolor), coyote …

Turkish Journal of Veterinary & Animal Sciences

The present study aimed to analyse the gestation length (GL) variability in locally born purebred Holstein dams (n = 1047), in a private farm, under Saharan climate. The overall GL mean was 278.73 ± 6.67 days. A general linear model revealed that the GL was significantly affected by calf sex (p = 0.035) with a minor increase of 0.19% in males, dam parity (p = 0.016) and calving season (p < 0.0001) including the shortest lengths recorded in heifers and during heat stress period. Moreover, a negative regression (-1.96%) in recent years was recorded in GL by the influence (p = 0.01) of years of birth, breeding, and calving of cows. Our findings show that cows that were inseminated and gave birth during the cold season (temperature-humidity index, THI < 74) had 11.54 days longer (p = 0.048) gestation period compared to animals that were inseminated and gave birth during the hot season (THI > 84). Similarly, the association (p = 0.003) between dam parity and calf sex revealed that the GL of multiparous cows that gave birth to male calves was higher (3.07 days) …
