    Can an herbivore affect where a top predator kills its prey by modifying woody vegetation structure?

    In large mammal communities, little is known about modification of interspecific interactions through habitat structure changes. We assessed the effects of African elephants (Loxodonta africana) on features of wo...

    Managing the Livestock–Wildlife Interface on Rangelands

    On rangelands the livestock–wildlife interface is mostly characterized by management actions aimed at controlling problems associated with competition, disease, and depredation. Wildlife communities (especiall...

    Demography of plains zebras (Equus quagga) under heavy predation

    In natural ecosystems, ungulate densities show strong temporal variations. The ecological processes driving these fluctuations are complex: food limitation and predation are both important and can interact. Su...

    Detecting predators and locating competitors while foraging: an experimental study of a medium-sized herbivore in an African savanna

    Vigilance allows individuals to escape from predators, but it also reduces time for other activities which determine fitness, in particular resource acquisition. The principles determining how prey trade time ...

    How key habitat features influence large terrestrial carnivore movements: waterholes and African lions in a semi-arid savanna of north-western Zimbabwe

    Within a landscape where prey has an aggregated distribution, predators can take advantage of the spatial autocorrelation of prey density and intensify their search effort in areas of high prey density by usin...

    Does the risk of encountering lions influence African herbivore behaviour at waterholes?

    A central question in the study of predator–prey relationships is to what extent prey behaviour is determined by avoidance of predators. Here, we test whether the long-term risk of encountering lions and the p...

    Do elephants prevent other African herbivores from using waterholes in the dry season?

    In some African protected areas, concerns have arisen about the influence of locally high elephant numbers on other forms of biodiversity. In arid and semi-arid savannas, surface-water resources are scarce and...

    Interference competition and temporal niche shifts: elephants and herbivore communities at waterholes

    Scarcity of resources may result in high levels of animal aggregation; interference competition can occur in such a scenario and play a role in resource acquisition. Here, we test the hypothesis that animals c...
