Estimating ungulate migration corridors from sparse movement data Open
Many ungulates migrate between distinct summer and winter ranges, and identifying, mapping, and conserving these migration corridors have become a focus of local, regional, and global conservation efforts. Brownian bridge movement models (…

The implications of large home range size in a solitary felid, the Leopard (<i>Panthera pardus</i>) Open
The size of the home range of a mammal is affected by numerous factors. However, in the normally solitary, but polygynous, Leopard (Panthera pardus), home range size and maintenance is complicated by their transitory social grouping behavi…

Spatial patterns of large African cats: a large‐scale study on density, home range size, and home range overlap of lions <i>Panthera leo</i> and leopards <i>Panthera pardus</i> Open
Spatial patterns of and competition for resources by territorial carnivores are typically explained by two hypotheses: 1) the territorial defence hypothesis and 2) the searching efficiency hypothesis. According to the territorial defence h…

Leopard density and interspecific spatiotemporal interactions in a hyena‐dominated landscape Open
Scavenging is widespread in the carnivore guild and can greatly impact food web structures and population dynamics by either facilitation or suppression of sympatric carnivores. Due to habitat loss and fragmentation, carnivores are increas…

A statistical framework for modelling migration corridors Open
Management of animal populations requires spatially explicit knowledge of movement corridors, such as those used during seasonal migrations. Global Positioning System (GPS) tracking data allow for mapping of corridors from directly observe…

Assessing the success of the first cheetah reintroduction in Malawi Open
In an effort to restore parts of their historical geographical range, and in recognition of their ability to restore ecosystem functioning and of the financial benefits they can provide through ecotourism, large carnivores have been reintr…

Leopard and spotted hyena densities in the Lake Mburo National Park, southwestern Uganda Open
Robust measures of animal densities are necessary for effective wildlife management. Leopards ( Panthera pardus ) and spotted hyenas ( Crocuta Crocuta ) are higher order predators that are data deficient across much of their East African r…

Modelling species distribution from camera trap by‐catch using a scale‐optimized occupancy approach Open
Habitat selection is strongly scale‐dependent, and inferring the characteristic scale at which an organism responds to environmental variation is necessary to obtain reliable predictions. The occupancy framework is frequently used to model…

Evidence for increasing human‐wildlife conflict despite a financial compensation scheme on the edge of a Ugandan National Park Open
The conflict of large carnivores and agro‐pastoral communities is a key driver of carnivore decline globally. The East African state of Uganda relies heavily on tourism as a GDP contributor and large carnivores are important for generating…

Habitat complexity and lifetime predation risk influence mesopredator survival in a multi-predator system Open
Variability in habitat selection can lead to differences in fitness; however limited research exists on how habitat selection of mid-ranking predators can influence population-level processes in multi-predator systems. For mid-ranking, or …

Unsustainable anthropogenic mortality disrupts natal dispersal and promotes inbreeding in leopards Open
Anthropogenic mortality of wildlife is typically inferred from measures of the absolute decline in population numbers. However, increasing evidence suggests that indirect demographic effects including changes to the age, sex, and social st…

View article: Experimentally disentangling intrinsic and extrinsic drivers of natal dispersal in a nocturnal raptor
Experimentally disentangling intrinsic and extrinsic drivers of natal dispersal in a nocturnal raptor Open
Equivocal knowledge of the phase-specific drivers of natal dispersal remains a major deficit in understanding causes and consequences of dispersal and thus, spatial dynamics within and between populations. We performed a field experiment c…

Context dependency of top‐down, bottom‐up and density‐dependent influences on cheetah demography Open
Research on drivers of demographic rates has mostly focused on top predators and their prey, and comparatively less research has considered the drivers of mesopredator demography. Of those limited studies, most focused on top‐down effects …

Calibrating an Individual‐Based Movement Model to Predict Functional Connectivity for Little Owls Open
Dispersal is crucial for population viability, yet understanding and predicting animal dispersal is notoriously difficult. We developed an individual-based model of natal little owl dispersal to assess whether individuals from expanding po…

Maximising camera trap data: Using attractants to improve detection of elusive species in multi-species surveys Open
Camera traps are a key tool in ecological studies, and are increasingly being used to understand entire communities. However, robust inferences continue to be hampered by low detection of rare and elusive species. Attractants can be used t…

The Conservation Costs of Game Ranching Open
The devolution of user rights of wildlife in southern Africa has led to a widespread land‐use shift from livestock farming to game ranching. The economic advantages of game ranching over livestock farming are significant, but so too are th…

Scent Lure Effect on Camera-Trap Based Leopard Density Estimates Open
Density estimates for large carnivores derived from camera surveys often have wide confidence intervals due to low detection rates. Such estimates are of limited value to authorities, which require precise population estimates to inform co…
