Carnivore Modification in North America: Perspectives on Neotaphonomy, Carnivore Use of Carrion, and Great Plains Bison Bonbeds
This dissertation addresses the use of carnivore modification studies in North America. Research in Africa has long been a dominant influence in zooarchaeological and taphonomic studies of carnivore modifications. The main question of interest driving the Old World research is timing of hominin …

A DYNAMIC LANDSCAPE OF FEAR: HUMAN IMPACTS ON CARNIVORE COMMUNITIES
<p>Mammalian carnivores are elusive, enigmatic species that often play keystone roles in ecosystems through direct (i.e., predation) and indirect (i.e., perceived predation risk) effects. Worldwide many carnivore species are experiencing rapid human-mediated population declines due to landscape …

Comparing density analyses and carnivore ecology in Madagascar's southeastern rainforest
… With few studies dedicated to Madagascar's carnivores, little is known about their ecology. My objectives were to 1) compare density estimation techniques applicable to enumerating rare and/or elusive carnivores, 2) investigate Malagasy carnivore distributions, abundance and density, and …

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 …

MICROBIAL GUARDIANS OF THE SAVANNAH: UNRAVELING THE GUT MICROBIOME FOR AFRICAN CARNIVORE CONSERVATION
… Namibia. Additional opportunistic samples from carnivore kill sites were also analyzed. No significant differences in alpha or beta diversity were detected between preserved and dried samples, although bacterial beta diversity differed between preserved and opportunistic samples (PERMANOVA). …

FACTORS INFLUENCING THE SPATIAL AND TEMPORAL STRUCTURE OF A CARNIVORE GUILD IN THE CENTRAL HARDWOOD REGION
… and top-down forces from higher trophic levels. Carnivore guilds play a vital role in the broader ecological community by stabilizing or destabilizing food webs. Consequently, factors influencing the structure of carnivore guilds can be critical to patterns in ecosystems. Coyotes (Canis latrans), …

Evaluation of organically certifiable alternate protein sources for production of the marine carnivore, cobia (Rachycentron canadum)
… sustainably. Cobia are high level marine carnivores and, as such, require relatively high dietary protein levels which usually are met through the use of fish meal. Fish meal supplies have become limited and costly, and alternate proteins must be utilized if future aquaculture production …

Effective monitoring techniques for carnivores and the role of a dominant mesocarnivore in structuring the carnivore community
… especially for cryptic species like carnivores. Using attractants can increase detections of carnivores, but they must be rigorously tested before use. Similarly, apex predators play a major keystone role in structuring ecosystems but are highly threatened and it is unknown if a …

THE USE OF TOOTH PIT AND TOOTH/JAW MEASUREMENTS TO IDENTIFY CARNIVORE TAXA RESPONSIBLE FOR DAMAGE ON SCAVENGED BONE
… determine whether it is possible to distinguish carnivore tooth mark characteristics from other carnivore tooth mark characteristics through two separate analyses: first by examination of tooth pitting and second from carnivore tooth and jaw measurements. This is accomplished by visual analysis …

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 …

Wild carnivore habitat use and community ecology in a biodiversity hotspot and human-wildlife conflict with pumas and dogs across Chile
… including pumas (Puma concolor). However, mesocarnivores are more abundant than large carnivores, live closer to human settlements, and drive community structure and processes in similar or different ways from large predators. Understanding both large and small carnivores' habitat use is key to …

The return of a large Carnivore: Recovery of the Cantabrian brown Bear and the Challenge of Coexistence in a human-dominated Landscape
… and abundance of many species. Large carnivores are especially sensitive to these alterations due to their trophic position, which entails great energetic and spatial requirements. These requirements in a human-dominated landscape generate negative interactions with people that have …

Unravelling the palaeobiology of the dinosaurian post crania and associated carnivore teeth from the early jurassic, Elliot formation in the Eastern Cape
… the specimen are three teeth of contemporaneous carnivores. Here, we describe the skeletal anatomy of AM 6147 and assess its phylogenetic affinities by scoring our findings in a phylogenetic data matrix. We also attempt to identify the carnivorous taxa to which the associated teeth may have …

Responses of Madagascar's Endemic Carnivores to Fragmentation, Hunting, and Exotic Carnivores Across the Masoala-Makira Landscape
The carnivores of Madagascar are likely the least studied of the world's carnivores, thus little is known about threats to their persistence. I provide the first long-term assessment of Madagascar's rainforest carnivore community, including: 1) how multiple forms of habitat degradation (i.e., …

Diagnosing Bone Fracture to Assess Early Hominin Behaviour, Meat-Eating, and Socioecology at FLK-Zinjanthropus, Olduvai Gorge, Tanzania
… method to diagnose hammerstone- and carnivore induced fracture. This is important because interpretations of hominin entry into the carnivore guild and evolution of meat-eating are based on rare tool and tooth marks in Oldowan (2.5-1.8mya) fossil assemblages. Consequently, estimating …

Monitoring and Conserving Wildlife Communities across Northern Botswana
… northern Botswana, with a focus on terrestrial carnivore species given their importance both ecologically and economically. My objectives were threefold: 1) estimate the distributions of the mammal community (n = 44 species) and evaluate community, group, and species-specific responses to …

Monitoring Program and Assessment of Coyote Predation for Olympic Marmots
… in causing marmot mortality. Through park-wide carnivore scat analysis I determined the spatial extent of coyote predation on Olympic marmots and the magnitude of coyote predation relative to other carnivore species. I used mtDNA analysis of scats to determine carnivore species and …
