New research into cheetah cub survival has refuted the theory that lions are a cub's main predator and that big cats cannot coexist in conservation areas. The study, published in the Journal of Zoology, found that cubs in the Kgalagadi Transfrontier Park were seven times more likely to survive then on the Serengeti Plains and that lions were not found to be the cubs' main predatory threat.

Previously, research on the Serengeti Plains found that only 4.8% of 125 cheetah cubs (Acinonyx jubatus) monitored from the den to adolescence survived. The that cheetah cubs are at high risk from lions has impacted conservation strategies as it is believed protected areas may not be suitable for if they cannot coexist with large predators.

In the latest study the authors visited a series of dens to study the litters of six adult female cheetahs. They found that in Kgalagadi 55% of litters and 53.6% of cubs survived to emergence. Lions were found to account for only 6.7% of mortality cases, in contrast with the Serengeti where 78.2% of cases were ascribed to lions.

The authors argue that rather than being the norm, the low survival of cheetah cubs reported on the Serengeti Plains may be exceptional. The plains are open landscapes, making cubs more vulnerable to predators.

There are also major differences in the cheetah's prey. In the Serengeti, gazelles are migratory, which may make it difficult for adult females to hunt. However in Kgalagadi, the steenbok population is sedentary and represents a constant source of food.

"Our study has shown that, contrary to popular belief, cheetah cub mortality may not always be inordinately high, and that lions are not necessarily their major predator," said Dr. Michael Gus Mills. "Cheetahs can coexist successfully in protected areas with other large carnivores."

A study of the litters of ONLY 6 Cheetahs is simply NOT enough to draw such confident conclusions.

I love how in particular in their effort to through out an untested assumption, they use another one to replace it blaming the flatness of the Serengeti.

As common sense as that might seem to them, it is just their assumption and nothing more, and hardly reason enough to dismiss the extensive, recorded, hard evidence of the threat of lions on the Cheetah population.

Of course they can co-exist. They have for millions of years in Africa. It's only when humans intervene that it throws out the balance.
