Red Panda around the world

The red panda (Ailurus fulgens, or shining-cat), is a small arboreal mammal native to the eastern Himalayas and southwestern China. It is the only extant species of the genus Ailurus. Slightly larger than a domestic cat, it has reddish-brown fur, a long, shaggy tail, and a waddling gait due to its shorter front legs. It feeds mainly on bamboo, but is omnivorous and may also eat eggs, birds, insects, and small mammals. It is a solitary animal, mainly active from dusk to dawn, and is largely sedentary during the day. The red panda has been classified as Vulnerable by IUCN because its population is estimated at fewer than 10,000 mature individuals. Although red pandas are protected by national laws in their range countries, their numbers in the wild continue to decline mainly due to habitat loss and fragmentation, poaching, and inbreeding depression. The red panda has been previously classified in the families Procyonidae (raccoons) and Ursidae (bears), but recent research has placed it in its own family Ailuridae, in superfamily Musteloidea along with Mustelidae and Procyonidae. Two subspecies are recognized.ANIMAL WORLD TokTil: Animal World - All about RED PANDA around the wor...

Saber-Toothed Cats In California Were Not Driven To Extinction By Lack Of Food

Credit: Mauricio Anton Citation: DeSantis LRG, Schubert BW, Scott JR, Ungar PS (2012) Implications of Diet for the Extinction of Saber-Toothed Cats and American Lions. PLoS ONE 7(12): e52453. doi:10.1371/journal.pone.0052453 When prey is scarce, large carnivores may gnaw prey to the bone, wearing their teeth down in the process. A new analysis of the teeth of saber-toothed cats and American lions reveals that they did not resort to this behavior just before extinction, suggesting that lack of prey was probably not the main reason these large cats became extinct. The results, published December 26 in the open access journal PLOS ONE by Larisa DeSantis of Vanderbilt University and colleagues, compares tooth wear patterns from the fossil cats that roamed California 12,000 to 30,000 years ago. Sabertoothed cats were not limited by food in California during the late Pleistocene. The saber-toothed cat and American lion were among the largest terrestrial carnivores that lived during their time, and went extinct along with other large animals approximately 12,000 years ago. Previous studies have suggested many reasons for this extinction, including a changing climate, human activity and competition from humans and other animals for food, which may have grown scarce as a result of these changes. In the current...
