Giving Compass' Take:

• It was popularly believed that poor care and handling was the reason all African wild dogs disappeared from the Serengeti National Park back in 1991, however, a recent study proves that competition with lions and hyenas was the likely cause. 

• What can we learn about national parks and their wildlife conservation programs from this article? Even though the decades old theory was debunked, what does it say about the challenges of wildlife conservation? 

Here's an article on wildlife conservation strategic plans for future generations. 

In 1991, all of the African wild dogs that previously lived in Serengeti National Park in Tanzania completely disappeared. In the debates that followed, one hypothesisbecame particularly controversial: in a series of papers, Roger Burrows, a researcher from the University of Exeter, United Kingdom, contended that the "handling" of Serengeti's wild dogs by researchers had led to the animals' deaths.

He said it was possible that the wild dogs had some degree of natural immunity to the rabies virus, and that darting the wild dogs with anesthetic and handling them, either to take blood samples from them, to vaccinate them, or to put radio collars on them, was extremely stressful to the animals
