Using Camera Stations To Investigate Occupancy Probability And Habitat Associations Of Island Spotted Skunks (Spilogale Gracilis Amphiala) On Santa Rosa And Santa Cruz Islands, Desirae Thomaier

Master's Theses

The California Channel Islands are unique in that two islands (Santa Rosa and Santa Cruz) support two endemic mesocarnivores, the island fox (Urocyon littoralis) and the island spotted skunk (Spilogale gracilis amphiala). Following the near-extinction of island foxes in the early 2000s, island spotted skunk populations increased significantly. Now that foxes have recovered, skunk captures have precipitously declined - possibly due to interspecific competition with foxes who have a similar diet but a larger body size and wider temporal niche. It has been proposed that skunks selectively use canyon bottoms and drainages with high vegetation cover and that these areas …

Adipocyte-Derived Cchamide-1, Eiger, Growth-Blocking Peptide 3, And Unpaired 2 Regulate Drosophila Melanogaster Oogenesis, Chad Simmons, Isaiah Williams, Tancia Bradshaw, Alissa R. Armstrong

Faculty Publications

In addition to energy storage, adipose tissue communication to other organs plays a key role in regulating organismal physiology. While the link between adipose tissue dysfunction and pathophysiology, including diabetes, chronic inflammation, and infertility, is clear, the molecular mechanisms that underlie these associations have not been fully described. We use Drosophila melanogaster as a model to better understand how adipose tissue communicates to the ovary. In this study, we utilized D. melanogaster’s robust genetic toolkit to examine the role of five adipokines known to control larval growth during development, CCHamide-1, CCHamide-2, eiger, Growth-blocking peptide 3, and unpaired 2 in regulating …

Outreach & Dna-Based Monitoring Facilitate 3-Fold Reduction In Seafood Mislabeling In Los Angeles Over 10 Years, Demian A. Willette, Kelli Andrade, Ben Fitzpatrick, Kesterlyn Wilson

Biology Faculty Works

Awareness and intervention can reduce fraudulent labeling in seafood. Using a 10-year longitudinal study approach, DNA-based monitoring data reveals a lower sushi mislabeling in Los Angeles restaurants over time. This is in part attributed to implemented recommendations by restaurants of a local academia-industry-government outreach initiative launched in 2018, The Los Angeles Seafood Monitoring Project. We found mislabeling was 3-fold lower among project-partnering restaurants than other restaurants. This difference was statistically significant, illustrating the combination of project partnering and implementation of recommendations was most impactful on reducing mislabeling rates. Lastly, the study period includes the COVID19 global pandemic, which additional monitoring …

Comparative Mechanical And Elastic Properties Of The Dorsal And Ventral Tendons In The Peduncle Of Harbor Porpoise (Phocoena Phocoena), Alexa R. Cesari, Jesse K. Placone, Nicole L. Ramo, Michael V. Rosario, Matthew Morris, Danielle S. Adams, Frank E. Fish

Biology Faculty Publications

Cetaceans swim via vertical movements of the tail. The tendons located in the caudal peduncle are attached to the caudal vertebrae to generate propulsive oscillations. Arguments have centered on whether the upstrokes and downstrokes of the tail and propulsive flukes are symmetrical or asymmetrical in time. Previous research from kinematics of swimming animals, muscle architecture and histology has supported both conditions. However, the composition and structure of the tendons suggest a potential mechanism to evaluate this disparity. In this study, the tendons of the caudal peduncle of the harbor porpoise (Phocoena phocoena) – specifically, the extensor caudae medialis …

Diverse Microbial Prey In The Guts Of Gelatinous Grazers Revealed By Microscopy, Terra C. Hiebert, Anne W. Thompson, Kelly R. Sutherland

Biology Faculty Publications and Presentations

Mucous mesh grazers including pelagic tunicates and thecosome pteropods play a key role in oceanic food webs. They are taxonomically and morphologically diverse and can be highly abundant. Using their fine mucous meshes, these pelagic grazers ingest a wide range of plankton prey and link pelagic and benthic marine ecosystems. Characterizing the diet of this group is central to fully understanding marine food webs and developing accurate food web models. However, gelatinous grazers are challenging to study owing to their physically delicate composition so studying their feeding ecology requires numerous complementary techniques. Microscopy has largely been supplanted by other methods, …

Coyote (Canis Latrans) Macronutrient Consumption And Diet Relative To Seasonality And Urbanization, Katherine C. B. Weiss, Sean C. P. Coogan, Pierre Deviche, Jesse S. Lewis, Savage C. Hess, Jan Schipper, Eric G. Strauss, Beckett Sterner

Biology Faculty Works

Diet selection informs the health, fitness, and behavior of wild predators. Due to assumptions that vertebrate prey contains similar compositions of macronutrients (i.e., protein, carbohydrates, and lipids), whole prey items traditionally define carnivore diets. However, increasing evidence suggests that prey differ in terms of their macronutrient compositions, particularly relative to body size. Furthermore, omnivorous predators, like coyotes (Canis latrans), integrate both prey and nonprey diet items whose macronutrient compositions vary. This is particularly important in urbanized systems, which introduce or alter the distributions of prey (e.g., domestic pets) and nonprey (e.g., ornamental plants) foods in ways that contribute …

Analyzing The Inhibition Of Chemical Compounds On Collagenase In P. Aeruginosa, Elaine Vanterpool

Student Posters

Pseudomonas aeruginosa is an opportunistic pathogen that poses significant challenges in clinical treatment due to its production of collagenase. This bacterium can cause several infections including pneumonia, meningitis, septicemia, and a host of other diseases. Collagenase acts as a key virulence factor by breaking down collagen in the host’s extracellular matrix, allowing bacteria to invade tissues. This study hypothesized that the effects of cell secreted collagenase would be inhibited by metronidazole, vanillin, and silver nanoparticles to reduce the pathogenicity of Ps. aeruginosa related infections. With the use of a spectrophotometric assay, collagenase activity was measured in treated and untreated bacterial …
