Elephants avoid hills

Understanding the factors that determine locations of elephant density hot-spots and use corridors is critical in helping to secure safe niches for elephants in the face of growing human encroachment on elephants' native habitat. In their study of elephant movements, the authors focused on the Samburu/Isiolo/Laikipia districts in northern Kenya, which represent an area of about 32,000 square kilometers of mostly unprotected habitat. This range is home to about 5,400 elephants.

The elephant charges. The ground trembles. Hearts racing, we are now sprinting through the forest dodging vegetation as the elephant plows right through it. The problem with being chased by an elephant, aside from their obvious size advantage, is they can run faster than you. While wild elephants can be dangerous animals under the right circumstances, other creatures are responsible for more deaths in Africa. Topping the list is the hippo, whose penchant for capsizing canoes that come too close results in the dumping of passengers who often can't swim. Buffalo, crocodiles, and lions are directly responsible for more deaths and injuries.
Mysterious pygmy elephants being tracked across Borneo by WWF
The same satellite system used by the U.S. military to track vehicle convoys in Iraq is helping World Wildlife Fund shed light on the little-known world of pygmy elephants in Borneo. This week marks the six-month anniversary of the first pygmy elephant's being captured and outfitted with a collar that can send GPS locations to WWF daily via satellite. Now, for the first time, the public can track the movements of the elephants online through an interactive web map.
Spicy peppers keep elephants out of farmers' fields
What do hot sauce aficionados and African elephants have in common? They both feel the burn of chilli peppers, the key ingredient for resolving human-elephant conflicts in Africa while raising money for farmers and conservation. Supported by the Wildlife Conservation Society (WCS) and other groups, the Elephant Pepper Development Trust (EPDT) has not only promoted the use of chilli peppers as a means of keeping elephants, buffalo, and other species away from important sources of human food, but has also introduced a viable cash crop to the economy of African nations.
On the basis of their findings, the authors suggest that large animals probably take a rather different view of their surroundings than do lightweight animals, and that this is probably especially true of heavyweight animals, like elephants, that are herbivores, for whom energy replenishment can be especially time consuming.
