Testing A Key Assumption Of Using Drones As Frightening Devices: Do Birds Perceive Drones As Risky?, Conor C. Egan, Bradley Blackwell, Esteban Fernández-Juricic, Page E. Klug

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife managers have recently suggested the use of unmanned aircraft systems or drones as nonlethal hazing tools to deter birds from areas of human-wildlife conflict. However, it remains unclear if birds perceive common drone platforms as threatening. Based on field studies assessing behavioral and physiological responses, it is generally assumed that birds perceive less risk from drones than from predators. However, studies controlling for multiple confounding effects have not been conducted. Our goal was to establish the degree to which the perception of risk by birds would vary between common drone platforms relative to a predator model when flown at …

The Parasite Giardia, Ashley Anderson

Honors Program: Senior Projects (Public)

The focus of this research is to better understand how this parasite works. The protozoan Giardia spp is found all over the world and in many species such as dogs, cats, and humans. From its two different forms to the microscopic size of both forms to its ability to destroy intestinal villi and cause symptoms like other parasitic infections, Giardia spp is continuously misdiagnosed. Upon further observation at veterinary clinics and researching science articles, Giardia spp is most commonly found in pets but has the potential to spread to humans via contaminated water. The most commonly infected humans are hikers, …

Cats And Conservationists: The Debate Over Who Owns The Outdoors, Dara M. Wald, Anna L. Peterson

New Directions in the Human-Animal Bond

Cats and Conservationists is the first multidisciplinary analysis of the heated debate about free-roaming cats. The debate pits conservationists against cat lovers, who disagree both on the ecological damage caused by the cats and the best way to manage them. An impassioned and spirited conflict, it also sheds light on larger questions about how we interpret science, incorporate diverse perspectives, and balance competing values in order to encourage constructive dialogue on contentious social and environmental issues.

On one side of the cat debate stand many environmentalists, especially birders and conservation organizations, who believe that outdoor cats seriously threaten native wildlife. …

Relationships Between Survival And Habitat Suitability Of Semi- Aquatic Mammals, Isidro Barela, Leslie M. Burger, Jimmy Taylor, Kristine O. Evans, Ryo Ogawa, Lance Mcclintic, Guiming Wang

United States Department of Agriculture Wildlife Services: Staff Publications

Spatial distribution and habitat selection are integral to the study of animal ecology. Habitat selection may optimize the fitness of individuals. Hutchinsonian niche theory posits the fundamental niche of species would support the persistence or growth of populations. Although niche-based species distribution models (SDMs) and habitat suitability models (HSMs) such as maximum entropy (Maxent) have demonstrated fair to excellent predictive power, few studies have linked the prediction of HSMs to demographic rates. We aimed to test the prediction of Hutchinsonian niche theory that habitat suitability (i.e., likelihood of occurrence) would be positively related to survival of American beaver (Castor canadensis), …

Involucrin, Cytokeratin 10 And Ki67 Expression In A Threedimensional Cultured Canine Keratinocyte Cell Line In Comparison To Canine Skin And Cutaneous Squamous Cell Carcinoma And A Pilot Study On Custom-Designed Sirna-Inv Transfection, Nongnut Assawawongkasem, Somporn Techangamsuwan, Prapruddee Piyaviriyakul, Pranom Puchadapirom, Achariya Sailasuta

The Thai Journal of Veterinary Medicine

Involucrin (INV) is a well-known early stage marker of terminal keratinocyte differentiation in humans. Besides its importance in human cancer, it has been predicted to be a prognostic marker in canine skin cancer. However, there is very little information available on canine INV. Therefore, for the first time, a three-dimensional (3D) cultured canine keratinocyte cell line was evaluated for the expression level of INV and two other cancer prognostic parameters, cytokeratin 10 (CK10) and Ki67, compared to that in canine normal skin (CN) and cutaneous squamous cell carcinoma (CSCC) cells. The INV protein and transcript expression levels were significantly (p < 0.005) higher in canine CN compared to in CSCC, whereas Ki67 expression levels were significantly (p < 0.05) lower in CN than in CSCC. The culture of a commercial canine keratinocyte cell line (CPEK; CELLnTEC Advanced Cell Systems, Switzerland) to produce the 3D epidermal skin was successfully achieved under an air-liquid interface for 14 d of culture. There was no statistical difference in the INV and CK10 expression levels between the 3D-cultured CPEK cells and CN. A custom designed INV siRNA transfected at 300 pmol showed the high efficacy of INV knockdown with minimum cytotoxicity to cultured CPEK cells, significantly reducing the INV mRNA expression level after 5 h transfection for up to 48 h. This is the first report on the custom design of siRNA transfection in monolayer cultured CPEK cells for INV gene knockdown in dogs and it could be useful for future studies on the carcinogenesis of CSCC.

Risk Factors For Prolonged Postparturient Vaginal Discharge In Sows, Nguyen Hoai Nam

Thoroughbred Racehorse Welfare Through The Lens Of ‘Social License To Operate—With An Emphasis On A U.S. Perspective, Camie Heleski, C. Jill Stowe, Julie Fiedler, Michael L. Peterson, Colleen Brady, Carissa Wickens, James N. Macleod

Agricultural Economics Faculty Publications

This review addresses the question of whether Thoroughbred horse racing is sustainable in the context of current social values. A recently acknowledged framework, known as ‘Social License to Operate’ (SLO), provides us with a lens through which to view and assess racehorse welfare. In multiple surveys of the general public, the horse owning public, and university students, the primary topics of concern regarding Thoroughbred racing show considerable concordance: concern about catastrophic injuries—particularly as related to track surfaces, concern over the racing of two-year-olds, whip use by jockeys, drug/medication policies, and aftercare opportunities for retired Thoroughbred racehorses. Legitimacy of an industry, …

Rabies Management Implications Based On Raccoon Population Density Indexes, Dennis Slate, Brandi D. Saidy, Ashlee Simmons, Kathleen M. Nelson, Amy Davis, Timothy P. Algeo, Stacey A. Elmore, Richard B. Chipman

United States Department of Agriculture Wildlife Services: Staff Publications

An estimate or index of target species density is important in determining oral rabies vaccination (ORV) bait densities to control and eliminate specific rabies variants. From 1997–2011, we indexed raccoon (Procyon lotor) densities 253 times based on cumulative captures on 163 sites from Maine to Alabama, USA, near ORV zones created to prevent raccoon rabies from spreading to new areas. We conducted indexing under a common cage trapping protocol near the time of annual ORV to aid in bait density decisions. Unique raccoons (n = 8,415) accounted for 68.0% of captures (n = 12,367). We recaptured raccoons 2,669 times. We …
