Rehabilitation Research Returns Orphaned Cheetahs to the Wild
Sean Mowbray - Mongabay June 2022
- A long-running program in Namibia has shown how orphaned cheetahs can be successfully rewilded, presenting a rehabilitation template for wild-born, captive-bred individuals of other species.
- The program by the Cheetah Conservation Fund took in 86 young cheetahs orphaned due to human-wildlife conflict, and eventually released 36 of them between 2004 and 2018.
- Twenty-seven of the cheetahs eventually became independent in the wild, while one female went on to raise two cubs — the “pinnacle of success” for any wildlife reintroduction effort.
- The study authors and independent experts agree that having safe release sites — where the newly reintroduced animals won’t run the risk of conflict with humans or other predators — and rigorous post-release monitoring are key to rehabilitation success.

A Speedy Trial: What It Takes to Be the Fastest Land Predator
Nagoya Institute of Technology - June 2021
- What makes cheetah the fastest land mammal? Why aren't other animals, such as horses, as fast? While we haven't yet figured out why, we have some idea about how.
- Cheetahs, as it turns out, make use of a "galloping" gait at their fastest speeds, involving two different types of "flight": one with the forelimbs and hind limbs beneath their body following a forelimb liftoff, called "gathered flight," while another with the forelimbs and hind limbs stretched out after a hind limb liftoff, called "extended flight". Of these, the extended flight is what enables cheetahs to accelerate to high speeds, and it depends on ground reaction forces satisfying specific conditions; in the case of horses, the extended flight is absent.
- Additionally, cheetahs show appreciable spine movement during flight, alternating between flexing and stretching in gathered and extended modes, respectively, which contributes to its high-speed locomotion. However, little is understood about the dynamics governing these abilities.

Cheetahs' Inner Ear is One-of-a-Kind, Vital to High-Speed Hunting
American Museum of Natural History - February 2018
Summary by Matt Warren on Science.org:
- The cheetah is built for running, with long limbs and powerful muscles that propel it along as it chases down its prey. But a new study has found that the world's fastest land mammal has another, less obvious adaptation hidden away in its inner ear.
- Scientists suspected that the cheetah might also rely on a specialized vestibular system, the part of the inner ear that detects head movements and helps animals maintain their gaze and posture. Using computerized tomography scans, they created detailed 3D images of the inner ear from the skulls of cheetahs and other cat species, from leopards to domestic cats.
- They found that the vestibular system took up a much greater part of the inner ear in cheetahs than in any other cat. The cheetahs also had elongated semicircular canals, parts of the system involved in head movement and eye direction. These features help the animal catch dinner by letting it keep its head still and its eyes on the prize, even when the rest of its body is rapidly moving, the researchers write in Scientific Reports.
- The extinct giant cheetah did not have the same features, suggesting that the distinct vestibular system evolved fairly recently, they say.
