Spatiotemporal Partitioning Of Two Invasive Ungulates In Guam [Abstract], Kelly J. Koriakin, Kurt C. Vercauteren, Nathan P. Snow, D. Buck Jolley

United States Department of Agriculture Wildlife Services: Staff Publications

Interspecific interactions are crucial in shaping ecosystem dynamics (Connell 1983, Tilman 1987, Barbosa and Castellanos 2005). Non-native ungulates have been introduced across the globe (Ferretti and Lovari 2014, Volery et al. 2021) and in environments where multiple invasives thrive, these co-occurring sympatric species may shift spatiotemporal patterns to minimize interspecific competition (Schoener 1974, Chesson 2000). Spatiotemporal shifts can lead to cascading effects to the native flora and fauna (Simberloff and Von Holle 1999). Given the potential negative impacts, understanding these interactions is vital for effective management of these ecosystems.

Spatial Analysis Of Socioeconomic Factors At Found Locations Of Orphaned Mammals In Champaign County, Illinois, Usa, Colleen Elzinga, Stephanie Heniff, William Sander, William Marshall Brown, Csaba Varga, Samantha Sander

Human–Wildlife Interactions

Young mammals make up a significant portion of animals brought into wildlife rehabilitation centers. Unfortunately, some of these presumed orphaned individuals are inappropriately removed from their native habitat. As such, there is a need for educational community outreach centered on the proper identification of orphaned wildlife that benefit from human intervention, while maximizing limited resources of rehabilitation facilities. This study evaluated found locations of common mammalian orphans presenting from Champaign County to the University of Illinois Wildlife Medical Clinic, Illinois, USA, between 2015 and 2020. The found locations of the orphans (99 Virginia opossums [Didelphis virginiana], 80 common …

Investigation Of The Causative Agent Of Canine Leproid Granuloma Infection Cases In The Northeastern United States, Nicole J. Marcotte

Honors Theses and Capstones

Canine leproid granuloma syndrome (CLGS) is a form of disease in dogs of many breeds that is characterized by a skin infection in the subcutis and/or dermis. The granulomas that form as a result of infection are typically non pruritic, alopecic, raised, and firm. These mass-like granulomas can ulcerate, causing further infection beneath the skin surface, and are present in areas of the body such as the ears, head, neck, and extremities. CLGS has been known to infect dogs of different breeds and ages, but has most commonly been reported to infect shorthaired, large sized breeds. This disease is suspected …

Molecular Characterization Of Fecundity-Related Gene Regions In Some Of Türkiye’S Native Sheep Breeds, Ramazan Aymaz, Fulya Özdi̇l, Yalçın Yaman

Turkish Journal of Veterinary & Animal Sciences

In this study, the BMP15 and GDF9 gene regions were examined through DNA sequencing in some native sheep breeds of Türkiye (Kıvırcık, Karacabey Merino, Chios, Gökçeada, Çine Çaparı, Awassi, and Karakacan). In the BMP15 exon 2 region, two single nucleotide polymorphisms (SNPs) were identified: one synonymous SNP, P248P (proline/proline), and one nonsynonymous SNP, L251P (leucine/proline), resulting in a missense mutation. In the GDF9 exon 1 region, only a nonsynonymous SNP, R87H (histidine/ arginine), was found. In the GDF9 exon 2 region, four SNPs were identified: two nonsynonymous SNPs, E241K (glutamate/lysine) and V332I (valine/isoleucine), and two synonymous SNPs, L159L (leucine/leucine) and …

Ethyl-Iophenoxic Acid As A Serum Marker For Oral Baiting Of Tasmanian Devils, Ruth Pye, David Nichols, Sally A. Nofs, Amy T. Gilbert, Andrew S. Flies

United States Department of Agriculture Wildlife Services: Staff Publications

Oral baits containing vaccines, medicants or toxicants have been delivered to a broad range of wildlife species to protect against or treat disease, or suppress populations. Ethyl-Iophenoxic acid (Et-IPA) is used as a biomarker to determine oral bait consumption by wildlife species to assess and refine baiting strategies. Et-IPA is a persistent biomarker in many eutherian mammal species but not in the two marsupial species, swamp wallaby (Wallabia bicolor) and brushtail possum (Trichosurus vulpecula), tested to date. Et-IPA has not previously been evaluated in carnivorous marsupials. The Tasmanian devil (Sarcophilus harrisii), the largest extant …

Desaix, Amy J. Davis, Courtney F. Bowden, Michael A. Tabak, Arianna Manunza, Valentin Adrian Bâlteanu, Marcel Amills, Laura Iacolina, Pamela Walker, Carl Lessard, Antoinette J. Piaggio

United States Department of Agriculture Wildlife Services: Staff Publications

The rapid expansion of wild pigs (Sus scrofa) throughout the United States has been fueled by unlawful introductions, with invasive populations causing extensive crop losses, damaging native ecosystems, and serving as a reservoir for disease. Multiple states have passed laws prohibiting the possession or transport of wild pigs. However, genetic and phenotypic similarities between domestic pigs and invasive wild pigs—which overwhelmingly represent domestic pig and wild boar hybrids—pose a challenge for the enforcement of such regulations. We sought to exploit wild boar ancestry as a common attribute among the vast majority of invasive wild pigs as a means …

Effects Of Ungulate‐Proof Fencing On Space Use By Wild Pigs, Kelly Koriakin, D. Buck Jolley, Benjamin Smith, Kurt C. Vercauteren, Nathan P. Snow

United States Department of Agriculture Wildlife Services: Staff Publications

Wild pigs (Sus scrofa) are a highly adaptable species that have invaded many regions and cause significant damage throughout the world. Ungulate‐proof fencing is increasingly used in conjunction with other control techniques to manage wild pig populations. However, little is known about how fencing affects wild pig space use behaviors and whether any changes may be exploited to increase efficacy of control activities. Our goal was to understand how wild pigs altered their space use behaviors in response to newly constructed fencing. Specifically, we examined for changes in space use area (home range and core area), increases in …

Relief Displacement Of Airborne Objects, Esteban Fernández-Juricic, Joe Crumpton, Morgan B. Pfeiffer, Sathishkummar Saiappan, Jared A. Elmore, Landon R. Jones, B. Santhana Krishnan, Raymond B. Iglay, Bradley F. Blackwell

United States Department of Agriculture Wildlife Services: Staff Publications

The increasing availability of unoccupied aircraft systems (UAS, also referred to as drones) has led to their use in taking vertical aerial photographs at relatively small spatial scales. These photographs can be used to measure the distances between objects appearing in the photographs. However, relief displacement can cause an object above or below ground level to appear at a point in a vertical aerial photograph that is not directly in-line with the object’s actual location, causing a measurement error. A UAS was used in this study as a photographed airborne object because its location and altitude could be controlled. We …

Efficacy Of Gonacon Fertility Control Against Prairie Dogs And Potential For Uses On Other Rodent Species, Aaron B. Shiels, Emily W. Ruell, Jason E. Bruemmer

United States Department of Agriculture Wildlife Services: Staff Publications

Use of a contraceptive (i.e., fertility control) is attractive for rodent management where lethal control is unwanted. Although population reduction is generally unachievable with small-scale, short-term contraceptive use, reduced juvenile recruitment is achievable. The injectable immunocontraceptive vaccine GonaCon (active ingredient: gonadotropin releasing hormone [GnRH]) was registered in 2022 by the United States Environmental Protection Agency (EPA) for controlling fertility of female prairie dogs (Cynomys, a type of ground squirrel) in urban/suburban settings. Here we: 1) describe past research, including a replicated field study in Colorado (GonaCon treatment vs. control sites) testing efficacy of GonaCon in prairie dogs, which …
