Animal movement is a complex spatiotemporal phenomenon that has intrigued researchers
from many disciplines. Interactions among animals, and between animals and the …

Choices of the spatial and temporal dimensions of ecological investigations define their
scale. In this paper, I identify some of the ways that issues of scale challenge ecologists in …

Grazing distribution patterns of large herbivores are affected by abiotic factors such as slope
and distance to water and by biotic factors such as forage quantity and quality. Abiotic …

We examined movements and habitat use by female Rocky Mountain elk (Cervus elaphus)
and mule deer (Odocoileus hemionus) using a large telemetry data set collected over 6 …

Scale-free foraging patterns are widespread among animals. These may be the outcome of
an optimal searching strategy to find scarce, randomly distributed resources, but a less …

We investigated the spatial distribution of radio-marked wildebeest (Connochaetes taurinus)
in the Serengeti ecosystem in relation to the distribution of their food resources, comparing …

Habitat selection can be considered as a hierarchical process in which animals satisfy their
habitat requirements at different ecological scales. Theory predicts that spatial and temporal …

Foraging animals are expected to adjust their path according to the hierarchical spatial
distribution of food resources and environmental factors. Studying such behaviour requires …

We define perceptual range as the distance from which an animal can perceive key
landscape elements, such as distant patches of forested habitat. We argue that perceptual …

Few experimental studies have tested theoretical predictions regarding the movement
strategies of large herbivores and their consequences for foraging efficiency. We therefore …
