Wild dogs record 2,500-mile trek across Africa in search of a mate

What the report says

BBC World News reports that three African wild dog brothers completed a record 2,485-mile trek across Zambia in search of a mate, the longest distance scientists have documented for an African land mammal making that kind of one-way journey. The animals covered about 4,000km over eight months, moving through a landscape increasingly fragmented by human development and avoiding large urban and industrial areas.

The study, published in the journal Ecology, is being presented as evidence that some wild dog populations in eastern and southern Africa may still be connected across broad areas. Researchers said the route suggests the species can navigate between wildlife strongholds despite roads, towns and farms, though the journey also exposed how dangerous the landscape remains. In the same study, other collared wild dogs died in illegal snares, and two of three females tracked by researchers did not survive.

African wild dogs are among Africa’s rarest predators, with only about 6,000 thought to remain in the wild. Because they cannot breed within their birth pack, young adults disperse to find mates and new territory. Conservationists say the findings support efforts to maintain natural corridors linking protected areas, so animals with wide-ranging habits can move safely between them. The broader significance is that connected landscapes may be essential for the species’ long-term survival despite ongoing pressures from human expansion and poaching.
