“…Even within study sites, wild dogs were found to occur at lower density where lions are more abundant (Mills and Gorman 1997;Creel and Creel 2002). Lions predate on wild dogs and exclude them from rich foraging patches (Mills and Biggs 1993;Van Heerden et al 1995;Creel and Creel 1996, 1998, 2002Mills and Gorman 1997;Van Dyk and Slotow 2003), whereas spotted hyaenas negatively affect wild dogs mainly by stealing food (Fanshawe and FitzGibbon 1993;Fuller et al 1995;Creel and Creel 1996, 1998, 2002Carbone et al 1997Carbone et al , 2005Gorman et al 1998). These factors can reduce foraging efficiency and increase mortality rates and thus may have profound consequences on the population dynamics of wild dogs.…”

Competitive interactions can be an important ecological factor in shaping species composition and abundance, with resulting implications for the conservation of inferior competitors. Endangered African wild dogs Lycaon pictus are known to suffer from interference competition with lions Panthera leo and spotted hyaenas Crocuta crocuta. Wild dogs have previously been shown to avoid areas frequented by superior intraguild competitors. Here, we tested the hypothesis that wild dogs also avoid lions and spotted hyaenas in time.To this end, daily activity patterns of sympatric social groups of the three species were recorded simultaneously by multiple observers in Hluhluwe-iMfolozi Park, South Africa. Wild dogs showed significantly different daily activity patterns compared to lions and spotted hyaenas, suggesting temporal niche separation. Our results raise the question whether conserving competing predators in small fenced conservation areas will lead to management-induced niche shifts.Saleni et al.

“…Cooperative hunting has often been observed in social carnivores (lions : Cooper 1991;Packer et al 1990, Schaller 1972, Stander 1992, Van Orsdol 1984wild dogs: Creel and Creel 1995, Estes and Goddard 1967, Fanshawe and Fitzgibbon 1993hyenas: Kruuk 1972, Mills 1990wolves: Mech 1970). Individual food intake across hunt group sizes in some carnivore populations tended toward a U-shaped distribution, with one maximum for single hunters and sometimes a second maximum for the largest groups (Caro 1994;Packer et al 1990).…”

Cooperative hunting roles among taï chimpanzees

All known chimpanzee populations have been observed to hunt small mammals for meat. Detailed observations have shown, however, that hunting strategies differ considerably between populations, with some merely collecting prey that happens to pass by while others hunt in coordinated groups to chase fast-moving prey. Of all known populations, Taï chimpanzees exhibit the highest level of cooperation when hunting. Some of the group hunting roles require elaborate coordination with other hunters as well as precise anticipation of the movements of the prey. The meat-sharing rules observed in this community guarantee the largest share of the meat to hunters who perform the most important roles leading to a capture. The learning time of such hunting roles is sometimes especially long. Taï chimpanzee males begin hunting monkeys at about age 10. The hunters' progress in learning the more sophisticated hunting roles is clearly correlated with age; only after 20 years of practice are they able to perform them reliably. This lengthy learning period has also been shown in some hunter-gatherer societies and confirms the special challenge that hunting represents.

“…Two additional factors thought to influence the group size and the group composition of predators are risk of predation and interspecific contests over food (Alexander 1974, Lima & Dill 1990, Fanshawe & Fitzgibbon 1993. Dolphins are marine predators that are preyed upon by certain shark species and this predation pressure may influence dolphin behavior and distribution (Wells et al 1980, Heithaus 2001.…”

“…However, the influence of these interactions on the feeding success of dolphins has not been measured. The presence or absence of hunters from other species influences the feeding success during a kill of terrestrial predators (Waser 1987, Gittleman 1989, Fanshawe & Fitzgibbon 1993. Thus, other things being equal, one would expect that dolphin feeding success would be affected by the presence or absence of sharks.…”

“…This study indicates that interspecific contests over food influence dolphin food intake and perhaps also dolphin group size. determines the outcome of interspecific contests over food (Waser 1987, Fanshawe & Fitzgibbon 1993. In contrast, little is known about this type of interspecific interactions among marine predators due to their relative inaccessibility: they range widely, hunt at depth and occur frequently in murky waters or in the open ocean.…”
