PREY PREFERENCES OF THE AFRICAN WILD DOG LYCAON PICTUS (CANIDAE: CARNIVORA): ECOLOGICAL REQUIREMENTS FOR CONSERVATION

Periaortic haemangiosarcoma in an African wild dog (Lycaon pictus).

A 9-year-old apparently healthy male African wild dog (Lycaon pictus) was found dead in its enclosure at the De Wildt Cheetah and Wildlife Centre. Necropsy revealed a pericardium distended by approximately 250 ml of thick blood. A soft, red, lobulated mass was attached to the periaortic fat between the level of the aortic valves and the pericardial reflection. Histologically, the mass was consi...

Isoflurane anaesthesia in an African wild dog, Lycaon pictus.

Anaesthesia was required in a captive female African wild dog (Lycaon pictus) for surgical wound treatment. After it was immobilised with a medetomidine-ketamine combination, bradycardia, hypothermia, systolic hypertension and metabolic acidosis were observed. Surgical anaesthesia was maintained with a 1% end-tidal isoflurane concentration. A decrease in the arterial blood pressure, rectal temp...

African Wild Dogs (lycaon Pictus) Can Subsist on Small Prey: Implications for Conservation

In mammalian predators, prey size typically increases with body size, such that most carnivores weighing .21.5 kg specialize on prey weighing 45% of their own mass. By hunting in packs, endangered African wild dogs (Lycaon pictus) are able to feed primarily on ungulates weighing .100% of their own individual mass and, in most populations, wild dogs specialize on such large prey. However, we sho...

Social dynamics and the cortisol response to immobilization stress of the African wild dog, Lycaon pictus.

The aims of the study were to characterize the cortisol response to immobilization stress in African wild dogs (Lycaon pictus) and to investigate the relationship between stress and sociality in these pack-living canids. Ad lib. observations were made on a captive pack of 19 wild dogs. Individuals were classified as either dominant or subordinate. Cardinal and ordinal dominance indices were als...
