The most detailed study to date of ancient predators trapped in the La Brea Tar Pits is helping Americans understand why today we're dealing with coyotes dumping over garbage cans and not saber-toothed cats ripping our arms off.

Tourists on safari can provide wildlife monitoring data comparable to traditional surveying methods, suggests new research. The researchers analyzed 25,000 photographs from 26 tour groups to survey the population densities of five top predators (lions, leopards, cheetahs, spotted hyenas, and wild dogs) in northern Botswana, making it one of the first studies to use tourist photographic data for this purpose.

Giving credence to the saying, 'While the cat's away, the mice will play,' a new study indicates that pumas and medium-sized carnivores lie low when they sense the presence of humans, which frees up the landscape for rodents to forage more brazenly.

Researchers have accessed data on more than 19 million cats and have learned that most cats continue to put on weight as they age.

The humble house mouse has dramatically shaped parasitic Toxoplasma gondii populations in West Africa and around the world, according to new research. As different strains affect their hosts differently, the research provides insights into which populations are infecting humans and animals and suggests mechanisms for their intercontinental spread.

Like many urban singles, the mountain lion P-22 lives a solitary life in a too-small habitat. And he has a hard time finding a mate in the big city.

Many companies are working on materials that would be as light and resistant as plastic but at the same time fully biodegradable. What if they could be made from... rubbish? A modern, ecological (waste-free—the conversion of raw material to product reaches 100%) and economical (does not require high temperatures or expensive catalysts) method of obtaining organic monomers is coming into being at the IPC PAS.

In 1979 the government of the Democratic Republic of Sudan and the government of Italy began working together to survey the incredible wildlife in the forests of Sudan's Southern National Park in preparation for drawing up what they called a "Master Plan" for protecting the park.

Let's be clear—tigers are perilously close to extinction.

Many of us were taught that "scruffing" a cat—or grabbing the animal by the loose skin at the back of the neck—is not only an effective mode of restraint, but also causes cats to relax. The thought behind this is that kittens relax when their mom carries them by the scruff.
