Article
Nest site fidelity is a common behavioral trait among birds that can positively influence reproductive success when there is spatial heterogeneity and temporal predictability in nest site quality. Nest site fidelity in wild turkeys (Meleagris gallopavo) has received little attention in the literature despite providing a potential link to nesting su...

Grass Carp Ctenopharyngodon idella were introduced in North America to control aquatic vegetation in small, closed systems. However, when they escape into larger systems in which they can reproduce, they have the potential to cause significant declines and alterations in aquatic vegetation communities. These alterations can in turn affect native sp...

Background: As obligate scavengers utilizing similar habitats, interspecific competition undoubtedly occurs between resident black (Coragyps atratus) and turkey (Cathartes aura) vultures. In the interest of exploring how sympatric species coexist through habitat segregation, we examined resource selection of resident black and turkey vultures in t...
Article
Measurements of external contaminant exposures on individual wildlife are rare because of difficulties in using contaminant monitors on free-ranging animals. Most wildlife contaminant exposure data are therefore simulated with computer models. Rarely are empirical exposure data available to verify model simulations, or to test fundamental assumptio...

Article
Full-text available
Effective ocean management and conservation of highly migratory species depends on resolving overlap between animal movements and distributions and fishing effort. Yet, this information is lacking at a global scale. Here we show, using a big-data approach combining satellite-tracked movements of pelagic sharks and global fishing fleets, that 24% of...
Article
Animal movement and habitat selection are in part a response to landscape heterogeneity. Many studies of movement and habitat selection necessarily use environmental covariates that are readily available over large‐scales, which are assumed representative of functional habitat features such as resource availability. For widely distributed species,...
Article
Full-text available
As carrion feeders competing for a limited and ephemeral resource, avian scavengers are ideal model organisms to study mechanisms of niche partitioning. Previous work has focused on observations of species' interactions at carcasses, and although fruitful, the inclusion of behavior beyond that at carcasses , such as movement patterns, could yield a...
Article
Full-text available
Pelagic sharks are vulnerable to overfishing because of their low reproductive rates, generally low growth rates, and high catch rates in tuna and billfish fisheries worldwide. Pelagic sharks often migrate long distances, but they may also occur close to shore, making it difficult to classify their behaviour on the continuum from oceanic nomad to c...
Article
The Chernobyl Exclusion Zone (CEZ) is a ~ 4300 km2 area in Belarus and Ukraine that remains heavily contaminated with radiation from the nuclear accident of 1986. Long standing controversy persists on the fate of wildlife within the CEZ following human abandonment of the area. Human residency remains extremely sparse, and the CEZ has become a refug...
Article
Meleagris gallopavo (Wild Turkey) population dynamics are greatly influenced by female survival, and high female-survival rates may offset low reproductive rates and maintain stability in populations characterized by low productivity. Additionally, reproduction may incur a cost to annual survival, given the physiological stress associated with bree...
Article
The white marlin, Kajikia albida, is a highly migratory, prized sport fish of conservation concern. Improved understanding of white marlin ecology, including habitat use, will inform management measures. To improve white marlin movement knowledge in a region with limited information, we tagged 18 individuals off the eastern Yucatan Peninsula, Mexic...
Article
Full-text available
Overfishing is a primary cause of population declines for many shark species of conservation concern. However, means of obtaining information on fishery interactions and mortality, necessary for the development of successful conservation strategies, are often fisheries-dependent and of questionable quality for many species of commercially exploited...

Solar-powered GPS transmitters linked to the GSM cellular transmission system are a powerful new tool for avian research. Data collection can be researcher programmed or use dynamic fix (DF) rates that are automatically adjusted in accordance with battery charge. Lack of prior knowledge of fix (location) collection rates represents an obstacle to d...
Article
Full-text available
Knowledge of black vulture (Coragyps atratus) and turkey vulture (Cathartes aura) spatial ecology is surprisingly limited despite their vital ecological roles. Fine-scale assessments of space use patterns and resource selection are particularly lacking, although development of tracking technologies has allowed data collection at finer temporal and...
Article

As upper level predators, sharks serve an important role in marine ecosystems, but are often at risk from fisheries. Successful management of these species will require detailed information about their movements and distributions. 2.Using satellite telemetry, we investigated the long-term horizontal movements and seasonal distributions of shortfin...
Article
Abstract Although nearly 30 years have passed since the Chernobyl Nuclear Power Plant accident near the town of Pripyat, Ukraine, the status and health of mammal populations within the Chernobyl Exclusion Zone (CEZ) remain largely unknown, and are of substantial scientific and public interest. Information regarding the response of flora and fauna...

Full-text available
During the breeding season, male white-tailed deer (Odocoileus virginianus)have been reported to take excursions outside of their normal home ranges, likely in search of receptive females. However, we documented additional excursive movements by males during spring in north central Pennsylvania. From December 2011 – April 2012, we equipped 13 matur...
Article
Inadequate dosimetry is often the fundamental problem in much of the controversial research dealing with radiation effects on free-ranging wildlife. Such research is difficult because of the need to measure dose from several potential pathways of exposure (i.e., internal contamination, external irradiation, and inhalation). Difficulties in quantify...
Article
Full-text available
Despite the widespread use of aerial baiting to manage epizootics among free-ranging populations, particularly in rabies management, bait acceptance and seroconversion rates often are lower than required to eliminate spread of disease. Our objectives in this study, therefore, were to evaluate the performance of stratified bait distribution models d...
Article
Full-text available
Coyote (Canis latrans) depredation rates on white-tailed deer (Odocoileus virginianus) fawns are variable across the southeastern United States, perhaps due to varying dispersion of coyotes as related to social behavior and habitat preferences. To evaluate fawn predation risk related to coyote distribution, we studied home range patterns and habita...
Article
Full-text available
Recent advances in animal tracking technology have increased interest in the field of animal movement ecology. Numerous methods have been developed to extract information from animal movement paths that can be used to link movement behavior to external stimuli such as habitat and climatic conditions. Given the recent development of Global Positioni...

Raccoon ecology is poorly understood in bottomland hardwood systems, despite the fact that bottomland forests are considered high-quality raccoon habitat. We radio-marked 41 raccoons during 2008–2009 and estimated seasonal space use and habitat selection in a bottomland hardwood forest located within the Atchafalaya floodway system in Louisiana. Sp...
Article
Radiotelemetry is the standard method for monitoring wild turkey (Meleagris gallapavo) movements and habitat use. Spatial data collected using telemetry-based monitoring are frequently inaccurate due to triangulation error. However, new technology, such as Global Positioning Systems (GPS) has increased ecologists' ability to accurately evaluate ani...
Conference Paper
Full-text available
Space use and habitat selection of wild turkeys (Meleagris gallopavo) has been well studied in various upland landscapes, but information within bottomland hardwood systems is lacking. Turkeys in bottomland systems face unique situations (e.g., flooding) and turkey behavior observed in upland systems may not directly apply to bottomland systems. Th...
