Demographics Of Non-Hunted White-Tailed Deer Populations In Suburban Areas, Anthony J. Denicola, Dwayne R. Etter, Thomas Almendinger Jan 2008

Demographics Of Non-Hunted White-Tailed Deer Populations In Suburban Areas, Anthony J. Denicola, Dwayne R. Etter, Thomas Almendinger

Human–Wildlife Interactions

Burgeoning deer populations in urban and suburban areas, along with the inherent problems stemming from this increase, are becoming increasingly widespread. To address these problems, wildlife biologists need quality baseline data of herd composition for harvest and treatment forecasts for management and fertility control research programs. In this study, we provide white-tailed deer (Odocoileus virginianus) population data from 4 areas where localized suburban white-tailed deer populations were substantially reduced utilizing sharpshooting as a management tool. In each area, legal hunting was nonexistent for >10 years preceding the sharpshooting program. The areas ranged in size from 300 ha to …

Carnivores, Urban Landscapes, And Longitudinal Studies: A Case History Of Black Bears, Jon P. Beckmann, Carl W. Lackey Jan 2008

Carnivores, Urban Landscapes, And Longitudinal Studies: A Case History Of Black Bears, Jon P. Beckmann, Carl W. Lackey

Human–Wildlife Interactions

As urban landscapes expand across the globe, it becomes imperative to understand how these landscapes affect large carnivore populations. We examined the effects of humanaltered landscapes on age-specific fecundity and life history parameters for female black bears (Ursus americanus) in urban and wildland regions in the northern Sierra Nevada Mountains of Nevada, including the Lake Tahoe Basin. We followed 12 marked female bears in an urban environment and 10 females in wildland habitats from 1997–2006. Our results show that female bears in urban areas have higher age-specific fecundity rates than did wildland female bears. Despite this difference, female …


Trans Fatty Acids Provide Evidence Of Anthropogenic Feeding By Black Bears, Gregory W. Thiemann, Randal S. Stahl, Sharon Baruch-Mordo, Stewart W. Breck Jan 2008

Trans Fatty Acids Provide Evidence Of Anthropogenic Feeding By Black Bears, Gregory W. Thiemann, Randal S. Stahl, Sharon Baruch-Mordo, Stewart W. Breck

Human–Wildlife Interactions

Bears (Ursus spp.) that become conditioned to anthropogenic food sources pose a risk to human safety and generally need to be relocated, rehabilitated, or destroyed. Identifying food-conditioned bears may be difficult if the animal is not captured or killed while immediately engaged in the nuisance behavior. Fatty acid signature analysis has been used to examine the dietary habits of bears and other carnivores and is based on the predictable incorporation of ingested fatty acids into the consumer’s fat stores. Unusual fatty acids that are available in only a few food types may be particularly useful dietary markers. In this …


Evaluation Of Physical Barriers To Prevent Prairie Dog Colony Expansion, Gary W. Witmer, James Gionfriddo, Michael Pipas Jan 2008

Evaluation Of Physical Barriers To Prevent Prairie Dog Colony Expansion, Gary W. Witmer, James Gionfriddo, Michael Pipas

Human–Wildlife Interactions

Expansion of black-tailed prairie dog (Cynomys ludovicianus) colonies on public and private lands can result in damage to property. Physical barriers to prairie dogs can be used to minimize human–wildlife conflicts. We evaluated 17 existing barriers in the Fort Collins and Boulder, Colorado, areas. Most barriers were made of a single row of vinyl material; these barriers sustained high levels of damage, primarily from wind, and were frequently breached by prairie dogs digging underneath them. Barriers that included a vegetation and a vinyl barrier or a double-vinyl barrier were wind damaged and breached less frequently than the singlevinyl …


Relationship Between Raccoon Abundance And Crop Damage, James C. Beasley, Olin E. Rhodes Jr Jan 2008

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 …

Gnrh Immunocontraception Of Male And Female White-Tailed Deer Fawns, Lowell A. Miller, James P. Gionfriddo, Jack C. Rhyan, Kathleen A. Fagerstone, Donald C. Wagner, Gary J. Killian Jan 2008

Gnrh Immunocontraception Of Male And Female White-Tailed Deer Fawns, Lowell A. Miller, James P. Gionfriddo, Jack C. Rhyan, Kathleen A. Fagerstone, Donald C. Wagner, Gary J. Killian

Human–Wildlife Interactions

Immunocontraceptive vaccines based on gonadotropin-releasing hormone (GnRH) have been tested in adult white-tailed deer (Odocoileus virginianus), but their effects on fawns are unknown. The purpose of this study was to determine if early immunization against GnRH would induce a long-lasting immune response in fawns, and if it would delay or prevent sexual development. We gave primary and subsequent booster injections of a KLH-GnRH/Freund’s vaccine to 6 male and 6 female fawns. This vaccine contained the same active ingredients as GonaCon™ vaccine, but it contained Freund’s adjuvant instead of AdjuVac™ adjuvant. Two 450-μg injections were given 1 month apart …

Modeling Wildlife Damage To Crops In Northern Indiana, Mónica I. Retamosa, Lee A. Humberg, James C. Beasley, Olin E. Rhodes Jr. Jan 2008

Modeling Wildlife Damage To Crops In Northern Indiana, Mónica I. Retamosa, Lee A. Humberg, James C. Beasley, Olin E. Rhodes Jr.

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 …
