And there's no guarantee of a successful hunt: in 2008, possibly because of changes in water temperature, ocean currents and the distribution of prey, no whales were caught at all.
As solitary animals, tigers (especially males) establish and maintain their own territories, the size and nature of which vary with the number and distribution of prey, the presence of other tigers in the area, the nature of the terrain, the availability of water, and individual characteristics.
We were surprised to find, for instance, that the monthly distribution of prey was a poor predictor of the whale wave.
Bobcat activities are confined to well-defined territories, which vary in size depending on gender and the distribution of prey.
When predators influence the distribution of prey it is called a trait-mediated or behaviorally-mediated direct effect [5], [6].
Case [23] noted that rattlesnakes from the Sea of Cortés tended to dwarf on islands where the relative abundance of small lizards was greater than rodents, implying that the overall size distribution of prey had shifted towards a smaller mode.
Vahl et al. (2005a) emphasized that the effects of interference competition are largely determined by the spatial distribution of prey.
Predation risk, however, frequently leads to a clumped spatial distribution of prey, to dilute the risk [ 12, 13].
Interspecific predation is a second direct mechanism known to structure ecological communities, which may have even greater effects on the size and distribution of prey populations [ 3- 6].
We provide a global phylogeographic perspective of the origin of the dusky dolphin, and assess the historical patterns of gene flow related to the location of temperate, up-welling coastal regions that are tightly linked to the distribution of prey species.
Whether the subject is disease distributions, predator-prey interactions, specific organs and systems, sleep patterns, human locomotion, or the other myriad systems, Yakubu asserts that mathematical biology provides insight into questions that cannot be reasonably or adequately addressed in the lab or the field.
