New Crocodile Species Discovered in West Africa

Studying crocodiles in some of the world’s most remote and inaccessible places isn’t easy, but it’s all in a day’s work for researcher Matthew Shirley. It is also, as he says, a “crazy amount of fun”—even on the days when catching and studying crocodiles leaves him covered in his own blood. “I love cruising through [...]

Poaching of elephants and the illegal trade in their tusks and related ivory products were out of control in 2011, with more than 2,500 animals confirmed killed and thousands of kilograms of tusks seized by customs officials around the world. This was the worst year on record since the international ivory trade ban was established [...]

Lions vs. Cattle: Taste Aversion Could Solve African Predator Problem

Most of that decline has taken place over the past two decades, and experts are now predicting that the big cats could [...]

Should Captive-Bred Chimpanzees Have Full Endangered Species Act Protection?

In a move that’s probably long overdue, the U.S. Fish and Wildlife Service (FWS) announced last week that it will conduct a status review to determine if captive chimpanzees (Pan troglodytes) should be reclassified from “threatened” to the more protected status “endangered” under the Endangered Species Act (ESA). Wild-born chimpanzees have been fully protected under [...]

In Africa, Climate Change Wages War on Bodies, Not Just Lands

Annals of the Malaria War: Legions of Health Workers Launch an Attack

Dung Beetles Follow the Stars

Recent research has shown that African ball-rolling dung beetles (Scarabaeus satyrus) use strong light cues from the [...]

Why Pygmies Are Short: New Evidence Surprises

Why pygmies are short

Pygmy populations, scientists have speculated, may owe their abbreviated stature to natural selection pressures that allowed them to better adapt to dense tropical forests where heat is oppressive and food is scarce. “An outstanding question for many, many years among anthropologists and human geneticists has been what is the genetic basis of the short stature [...]

This ant-driven tree protection has large-scale implications for savanna landscapes, report zoologists Jacob Green and [...]

What information is contained in the call of a mammal? Some calls might reflect the internal emotional state of the animal, like fear or anxiety, or they can refer to an external object, agent, or event, like the presence of a predator. Rhesus monkeys, lemurs, baboons, and guinea pigs, for example, will produce calls when [...]

The history of penguins in Africa is a history of false starts. The first penguin pioneers that settled Africa millions of years ago all went extinct. But the penguins didn’t give up. They came back, swept there by ocean currents, and repopulated the African coasts. That’s what the palaeontologists Daniel Ksepka and Daniel Thomas conclude [...]
