Mammal Diversity Aided In Survival Over Deep Time

Lawrence LeBlond for RedOrbit.com In a first of its kind study, researchers from Vanderbilt University found that mammals´ best defense to adapting to climate change was diversity, and families with higher taxonomic diversity were better able to survive ongoing environmental changes. Larisa R. G. DeSantis, Assistant Professor of Earth and Environmental Sciences at Vanderbilt, led researchers in studying how North American mammals adapted to climate change over a 56-million-year...

Domestic dogs have followed their own evolutionary path, twisting Darwin's directive "Ëœsurvival of the fittest' to their own needs "“ and have proved him right in the process, according to a new study by biologists Chris Klingenberg, of The University of Manchester and Abby Drake, of the College of the Holy Cross in the US. The study, published in The American Naturalist today (20 January 2010), compared the skull shapes of domestic dogs with those of different species across...

A new look at limbs changes understanding of early carnivore locomotion More than a hundred years after its discovery, the limbs and vertebrae of a fossil have been pulled off the shelf at the American Museum of Natural History to revise the view of early carnivore lifestyles. Carnivores"”currently a diverse group of mostly meat-eating mammals like bears, cats, raccoons, seals, and hyenas"”had been considered arboreal in their early evolutionary history. But now that the skeleton...

Packs of hunting dogs, troops of baboons, herds of antelope: when people observe social animals, they are often struck by how intelligent they seem, and recent studies suggest that sociality has played a key role in the evolution of larger brain size among several orders of mammals. But new research from two evolutionary biologists, John Finarelli of the University of Michigan and John Flynn of the American Museum of Natural History, calls this hypothesis into question"”at least for the...

By Kozlowski, Adam J Gese, Eric M; Arjo, Wendy M ABSTRACT. - Successful coexistence of sympatric canid species often relies on the subdominant species' ability to reduce competition through the differential selection of niche space. Information regarding the process of niche selection and its effect on the structure of canid communities in the Great Basin Desert is unavailable. From Dec. 1999 to Aug. 2001, we quantified the spatial, dietary and temporal resource overlap of kit foxes (Vulpes...

In a new study published in the online-open access journal PLoS ONE, Per Christiansen at the Zoological Museum in Copenhagen, Denmark, reports the finding that the evolution of skull and mandible shape in sabercats and modern cats were governed by different selective forces, and the two groups evolved very different adaptations to killing. The cat family comprises some of the most specialized carnivores in the history of mammals, all exclusively eating flesh. The cat family consists of two...

The dog is a type of canid, a mammal in the order Carnivora. The term includes both wild (feral) and domestic variants, but commonly excludes other canids such as wolves. Over time, the dog has developed into hundreds of breeds with a great degree of variation. Intelligence Among dog lovers, dogs are generally valued for their intelligence. Both anecdotal evidence and scientific research suggest that dogs have a reasonably high intelligence. This intelligence is expressed...

The Polar Bear (Ursus maritimus) is a large mammal of the order Carnivora, family Ursidae (bears). It is a circumpolar species found in and around the Arctic Ocean and is the world's largest land carnivore. Adult males weigh from 400 to 600 kg and occasionally exceed 800 kg. Females are about half the size of males and normally weigh 200-300 kg. Adult males measure 2.4 to 2.6 m; females, 1.9 to 2.1 m. At birth, cubs weigh 600 to 700 g. Population estimates range from 16,000 to 35,000, with...
