Lack Of Human Awareness And The Need For Increased Public Education Regarding The Zoonotic Parasite, Baylisascaris Procyonis, Jacob L. Ogdee, Scott E. Henke, David B. Wester
Human–Wildlife Interactions
Baylisascaris procyonis is a large parasitic nematode found in the small intestines of raccoons (Procyon lotor), the definitive host, and causes larva migrans in humans and other animals. Humans can become infected by ingesting B. procyonis eggs, which can remain viable in the environment for years and adhere to vegetation, soil, water, raccoon feces, or hands. Parasitic infections manifest in humans with neural and ocular larva migrans, characterized by clinical symptoms of head and body tilt, circling, recumbency, ataxia, blindness, nervous behavior, paralysis, and coma, leading to death. Prevalence of B. procyonis in humans is unknown. However, human …

The Centers for Disease Control (CDC) and USDA Wildlife Services (WS) have been involved in an oral rabies vaccination (ORV) program for raccoons (Procyon lotor) that has slowed the westward spread of raccoon rabies. The objective of this study was to forecast the spread of the disease if an ORV zone was not maintained. A group decision-making process was designed to address the forecasting problem and was implemented using a group of 15 experts and 4 support personnel at a meeting at the USDA National Wildlife Research Center. Ten expansion regions were constructed that described the spread of …

Effects Of Waterfowl Hunting On Raccoon Movements, Shandra Nicole Frey, Michael R. Conover
Effects Of Waterfowl Hunting On Raccoon Movements, Shandra Nicole Frey, Michael R. Conover
Human–Wildlife Interactions
Nontarget wildlife may react to hunters with avoidance, ambivalence, or attraction, depending upon the frequency of contact and the consequences of past contacts. We studied raccoons (Procyon lotor) located within the Bear River Migratory Bird Refuge, Utah, before and during waterfowl hunting seasons to assess changes in the size of their distributions, locations, and travel distances. Raccoon distribution size did not change with the onset of hunting. Once hunting began, raccoons were located more frequently in areas with lower densities of hunters and less frequently in areas with higher densities of hunters. Raccoons also responded to the presence …
Evaluation Of Rhodamine B As A Biomarker For Raccoons, Tricia L. Fry, Todd Atwood, Mike R. Dunbar
Evaluation Of Rhodamine B As A Biomarker For Raccoons, Tricia L. Fry, Todd Atwood, Mike R. Dunbar
Human–Wildlife Interactions
The USDA/APHIS/Wildlife Services (WS) oral rabies vaccination program uses tetracycline, a broad-spectrum antibiotic and relatively reliable biomarker, to quantify vaccinebait uptake by raccoons (Procyon lotor). However, obtaining samples (e.g., bone or teeth) to assess tetracycline uptake is highly invasive, and sample preparation can be expensive. By contrast, rhodamine B, a commercially available dye, is absorbed systemically in growing tissues, including hair and whiskers, and can be observed under ultraviolet (UV) light as fluorescent orange bands. Our goal was to evaluate whether rhodamine B can be used as a biomarker to monitor bait uptake by raccoons. We began by …

Human–Wildlife Interactions
We evaluated the efficacy of an oral rabies vaccination (ORV) program conducted in Erie County, New York, from July through September, 2002–2005. Ingress of the raccoon (Procyon lotor) rabies variant first occurred along the southern border of Erie County, New York, during 1992 and began to spread northward at a velocity of 31 km/year. Fixed-wing aircraft dropped ORV baits in rural landscapes; helicopters, hand baiting, and bait stations distributed baits in suburban landscapes (x̄ bait densities ranged 59–118 baits/km2). Our study objectives were to quantify rabies case densities, evaluate efficacy of intervention efforts, and determine biological, …

Human–Wildlife Interactions
Comprehensive information on crop damage by wildlife species is critical if effective strategies for controlling wildlife damage are to be formulated. Discriminating how landscape composition and configuration attributes influence crop damage is important for implementing landscape management techniques to resolve human–wildlife conflicts. We analyzed crop damage data from 100 corn fields and 60 soybean fields located in the Upper Wabash River Basin of northern Indiana during 2003 and 2004. We used negative binomial regression to model the rate of damage to corn and soybean crops in response to local and landscape variables. Rate of crop damage was best predicted by …
Relationship Between Raccoon Abundance And Crop Damage, James C. Beasley, Olin E. Rhodes Jr
Relationship Between Raccoon Abundance And Crop Damage, James C. Beasley, Olin E. Rhodes Jr
Human–Wildlife Interactions
Wildlife damage to crops is a widespread concern among agricultural producers and wildlife professionals. In the United States, raccoon (Procyon lotor) damage to field corn (Zea maize) has become a serious concern, as raccoon depredation to corn has increased significantly in recent years. However, little information is available to suggest the underlying factors responsible for recent increases in raccoon depredation on agricultural crops because there is a limited understanding of the ecological factors influencing wildlife damage to crops at local scales. During 2004, we initiated a study to elucidate the ecological factors influencing depredation to field …

Management programs aimed at reducing wildlife damage to row crops rely on information concerning the spatial nature of wildlife damage at local and landscape scales. In this study we explored spatial patterns of wildlife damage within individual corn and soybean fields by describing relationships between specific locations where wildlife damage was recorded and distances from such locations to various habitat types that presumably influenced animal abundance and movements in our study area. Using stratified random sampling, we conducted depredation surveys of 100 corn fields and 60 soybean fields from May through October both in 2003 and 2004 and recorded the …
