Effects Of Translocation On Survival Of Nuisance Bears, Javan Bauder, D. Ruid, N. M. Roberts, B. Kohn, M. L. Allen

United States Department of Agriculture Wildlife Services: Staff Publications

Effective mitigation of human–wildlife conflict should aim to reduce conflicts while also minimizing wildlife mortality. Translocation is often used to mitigate human–wildlife conflict but translocated individuals may have reduced survival, which could negatively affect population growth and social acceptance of translocation as a management tool. Yet, non-translocated nuisance individuals may also have low survival due to inherent risks associated with nuisance behavior. We used a 38-year dataset of 1233 marked and translocated nuisance American black bears (Ursus americanus) as a model system with which to evaluate the impacts of translocation on nuisance bear survival. We used multi-state mark-recapture models to …

Threading The Needle: How Humans Influence Predator–Prey Spatiotemporal Interactions In A Multiple-Predator System, Asia Murphy, Duane R. Diefenbach, Mark Ternent, Matt Lovallo, David Miller

United States Department of Agriculture Wildlife Services: Staff Publications

Perceived predation risk and the resulting antipredator behaviour varies across space, time and predator identity. Communities with multiple predators that interact and differ in their use of space, time of activity and hunting mode create a complex landscape for prey to avoid predation. Anthropogenic presence and disturbance have the potential to shift interactions among predators and prey and the where and when encounters occur. We examined how white-tailed deer Odocoileus virginianus fawn spatiotemporal antipredator behaviour differed along an anthropogenic disturbance gradient that had black bears Ursus americanus, coyotes Canis latrans, bobcats Lynx rufus and humans present. We quantified (a) spatial …

Quantitative Proteomics And Phosphoproteomics Reveal Tnf-Α-Mediated Protein Functions In Hepatocytes, Rodrigo Mohallem, Uma K. Aryal

Department of Veterinary Clinical Sciences Faculty Publications

Increased secretion of proinflammatory cytokines, such as tumor necrosis factor-alpha (TNFα), is often associated with adipose tissue dysregulation, which often accompanies obesity. High levels of TNFα have been linked to the development of insulin resistance in several tissues and organs, including skeletal muscle and the liver. In this study, we examined the complex regulatory roles of TNFα in murine hepatocytes utilizing a combination of global proteomic and phosphoproteomic analyses. Our results show that TNFα promotes extensive changes not only of protein levels, but also the dynamics of their downstream phosphorylation signaling. We provide evidence that TNFα induces DNA replication and …
