Lead exposure in large carnivores in the greater Yellowstone ecosystem
… hunter-harvested ungulate gut piles. Some large mammalian carnivores, such as grizzly bears (Ursus arctos), are also known to target these gut piles as a food source while others, such as cougars (Puma concolor), avoid areas with high levels of human hunting pressure. I investigated whether …

Large carnivores and humans: understanding livestock predation patterns to alleviate conservation conflicts
El crecimiento de la población humana ha aumentado la demanda de recursos, modificando el paisaje y contribuyendo a la pérdida de biodiversidad. Los esfuerzos de conservación pueden verse dificultados por los impactos negativos que las especies pueden ejercer en las poblaciones humanas, conduciendo …

Movement analysis for monitoring predation by large carnivores : lions in Kruger National Park
Methods used to estimate the prey consumption by large carnivores include direct continuous observation, stomach content analysis, carcass observations and scat analysis. Continual observations are widely considered the best approach to estimate large carnivore diets, with lions (Panthera leo) …

Carnivore ecology and conservation : implications for tiger conservation and management in Nepal /
… landscapes, conservation and management of large carnivores has been a formidable challenge due to habitat fragmentation, degradation and loss, wildlife persecution, and poaching. Consequently, wide-ranging species like tigers are now relegated to small protected areas. I evaluated factors …

Managing the carnivore comeback: assessing the adaptive capacity of the Eurasian lynx (Lynx lynx) to cohabit with humans in shared landscapes
Conflicts between humans and large carnivores are one of the most visible examples of the challenges that arise when seeking to achieve coexistence between humans and wildlife. With their large spatial requirements and predatory behavior, large carnivores are among the most difficult species to …

Mechanisms facilitating coexistence between leopards (Panthera pardus) and their competitors in the Okavango Delta, Botswana
Large carnivores provide key ecological services to ecosystems, and full species assemblages are thought to be important in maintaining full ecosystem function. The African large carnivore guild represents one of the last functionally intact guilds of large carnivores on Earth, but relatively …

Cheetah (Acinonyx jubatus) mortality and survival in fenced reserves as part of a managed metapopulation across South Africa
Large carnivores require expansive habitat to meet their life history needs making them vulnerable to the loss and fragmentation of natural habitat. This, in addition to human persecution has led to substantial population and range reductions of most of the world’s large carnivores over the past …

Analysis of Drivers of Spring Alligator Hunting in Texas and Policy Implications
… wildlife decision-makers. As conflict between large carnivores and humans increase with habitat destruction and urbanization, managers are faced with finding a balance between carnivore conservation and human appeasement. Large carnivore hunters are often the hardest group to bring on board new …

Exploring the causes of and mitigation options for human-predator conflict on game ranches in Botswana: How is coexistence possible?
Large carnivores in southern Africa are threatened by habitat loss and persecution by humans. Game ranches have the potential to provide habitat for free-ranging predators, but carnivore depredation on game-stock can result in human-predator conflict, and the industry's role in predator …

Tails through time: leopard population dynamics in the Little Karoo
Large carnivores play a vital role in structuring our ecosystems, yet they face mounting threats such as habitat loss, prey reduction and persecution. These threats reduce their global distribution and impacts their population numbers. Protected areas can offer refuge for large carnivores, however …

A paleozoological perspective on predator extermination and white-tailed deer (Odocoileus virginianus Boddaert) overabundance in central Texas.
… to ecology. In central Texas several top carnivores including prehistoric Native American hunters have been extirpated or have had their historic ranges restricted, which has resulted in pest-level white-tailed deer (Odocoileus virginianus texana) populations in some areas. Predator …

The return of a large Carnivore: Recovery of the Cantabrian brown Bear and the Challenge of Coexistence in a human-dominated Landscape
The large increase in human population and resource consumption in recent centuries has altered much of the land surface, negatively affecting the distribution and abundance of many species. Large carnivores are especially sensitive to these alterations due to their trophic position, which entails …

Assessing the genetic diversity and structure of spotted hyena (Crocuta Crocuta) populations across Africa
… of structure was comparable to other mammals and large carnivores in the same distribution. Although there was evidence of gene flow between these regions the western appeared more differentiation from either the eastern or southern both of which shared considerable genetic material with each …

Conservation of leopards in Ayubia National Park, Pakistan
… Committee Chair: Dr. Daniel H. Pletscher Large carnivores are important for biodiversity and ecosystem function, yet are very difficult to conserve because of their large home ranges and conflicts with humans. I examined human-leopard conflicts in and near Ayubia National Park, Pakistan, …

The influence of habitat features and co-occurring species on puma (Puma concolor) occupancy across eight sites in Belize, Central America
Large carnivores play many vital biological, economic, and conservation roles, however, their biological traits (low population densities, cryptic behavior) make them difficult to monitor. Pumas have been particularly difficult to study because the lack of distinctive markings on their coats …

The density of leopards in a mixed-use landscape in the Western Cape, South Africa
Large carnivores face numerous threats, including habitat loss and fragmentation, direct killing, and prey depletion, leading to significant global range and population declines. Despite these threats, leopards (Panthera pardus) persist outside protected areas throughout most of their range, …
