Mammal diversity in the North Chickamauga Creek Gorge State Natural Area and the effects of internal fragmentation on the relative distributions of mammalian carnivores
… small to medium-sized mammalian predators (i.e., mesopredators) were predicted to be more concentrated in the adjacent forested areas. For the preliminary investigation, five transects containing scent stations were constructed in and surrounding the right-of-way. The tracks of 13 large mammalian …

Determinants of predator abundance in northern KwaZulu-Natal: top-down or bottom-up?
… I investigated whether the relative abundance of mesopredators, facultative scavengers, and an apex predator were affected primarily by bottom-up processes (prey abundance) or by top-down processes (predator abundance), or a combination of the two. Central to this study was elucidating the complex …

Landscape-scale mechanisms of biological pest control in a South Korean agricultural landscape
… by differences in the local stability of mesopredators across landscapes. In simple landscapes with locally unstable mesopredators, top predators stabilized predator-prey interactions and led to higher predation pressure than with mesopredators alone. These findings confirm empirical …

Densities, habitat-use, and mesopredator release of the ocelot in Belize
… species; this could hinder the conservation of mesopredators in areas where large top-carnivores are prioritized. I investigated the ecology of ocelots in Belize and examined the role of mesopredator release in the neotropical carnivore guild to determine if ocelots are limited by competition …

Characteristics, determinants and management of farmer-predator conflict in a multi-use dryland system, South Africa
… of relevant applied research. Most research on mesopredators in South Africa has been conducted in protected areas (PA) or at the level of a single farm, precluding the generalisation of results to broader regions, and therefore limiting our understanding of the conflict on farmlands more …

The effect of individual variability and larger carnivores on the functional response of cheetahs
… the rate at which prey are killed. Cheetahs are mesopredators and their behavior can be shaped by the need to avoid larger predators while hunting relatively large bodied and mobile prey. I used data from 34 years of observed cheetah hunts in Serengeti National Park in Tanzania to investigate how …

Landscape and population ecology of ring-necked pheasants
… common predators of pheasants. Both raptors and mesopredators were more likely to prey on pheasants in large fields than small ones. Predation by raptors could be minimized by increasing the amount of native grasses within fields. Still, pheasant populations were growing during my study, …

Exploring the eco-hydrological and predator movement effects of floating roads in the context of forest to bog restoration in the Flow Country
… that run against existing assumptions of how mesopredators interact with the landscape and prey, and that the combination of monitoring methods can Exploring the eco-hydrological and predator movement effects of floating roads in<br/>the context of forest to bog restoration in the Flow Country …

Utilizing an Integrated Approach to Explore Niche in a Complex Equatorial System
… to investigate coexistence of two abundant mesopredators in a nearshore environment. My findings suggest that the versatility of rock hind (Epinephelus adscensionis) and spotted moray eel (Gymnothorax moringa), including generalist dietary choices and individual differences in space use, …

Comparative abundance and ranging behaviour of brown hyaena (Parahyaena brunnea) inside and outside protected areas in South Africa
… protected areas. A significant finding was that mesopredators showed higher relative abundances in the unprotected areas. This suggests probable further human-wildlife conflict if mesopredator release continues to occur. Low levels of abundance in the unprotected areas, in conjunction with …

Seguimiento y gestión de sistemas depredadores-presa : aplicación a la conservación de fauna amenazada
… on methods of detecting and monitoring mammalian mesopredators. Their mostly nocturnal and elusive behaviour, together with the usual scarcity of resources, makes techniques such as indirect signs or camera trapping particularly useful. None of the techniques detected all the species of …

Causes and Implications of Fox Population Dynamics in Central Southern England
… organisms (i.e., bottom-up control) including mesopredators, especially in the absence of top, apex predators. Therefore, large-scale anthropogenic subsidisation of source populations could also exacerbate the rate of compensatory immigration by elevating regional average fox density. A …
