On CNN’s page there is an interesting article regarding research in Kenya exploring the social behaviour of zebras. Princeton researchers under a collaborative program called ZebraNet, have attached GPS devices to the necks of Grevy and Plains zebras. A particular emphasis behind the program is to gather data from the Grevy zebras, an endangered species whose numbers have dropped to 2000, as they social network, avoid becoming prey, and interact with others.
As a doctoral student at Duke University, Rubenstein was fascinated with how animals make decisions and why their societies form the way they do. He started studying equids — a family of mammals that includes horses, donkeys, and zebras — because they form associations among strangers.
He has also examined how the Grevy’s zebra social network — and he doesn’t mean Facebook or MySpace — may contribute to its endangerment. Associations between Grevy’s zebras are less close-knit than those of the Plains zebra, whose core societies consist of closed-membership harem-groups and bachelor groups.
In a harem, several females choose to live with one male that protects them against harassment in exchange for sex. Female Grevy’s zebras, on the other hand, don’t stay with one male for long periods of time, meaning they don’t have the benefit of a larger male watching out for them.
