Margaret Allen, Southern Methodist University Rodents get a bad rap as vermin and pests because they seem to thrive everywhere. They have been one of the most common mammals in Africa for the past 50 million years. From deserts to rainforests, rodents flourished in prehistoric Africa, making them a stable and plentiful source of food, says paleontologist Alisa J. Winkler, an expert on rodent and rabbit fossils. Now rodent fossils are proving their usefulness to scientists as they help shed...

University of Florida researchers presenting new fossil evidence of an exceptionally well-preserved 55-million-year-old North American mammal have found it shares a common ancestor with rodents and primates, including humans.The study, scheduled to appear in the Oct. 11 online edition of the Zoological Journal of the Linnean Society, describes the cranial anatomy of the extinct mammal, Labidolemur kayi. High resolution CT scans of the specimens allowed researchers to study minute details in...

A resilient rodent from the horn of Africa has begun charming scientists around the world.  Resistant to cancer and aging better than Sean Connery, the remarkable, if somewhat unattractive, naked mole rat is proving to be a biological wonder and a new source of scientific inquiry. "They really are from Mars, I think," Thomas Park, biological sciences professor at the University of Illinois at Chicago, told the Associated Press. Able to live up to 30 years, these 3 to 4 inch East African...

Naked Mole Rat, the Only Known Cancerless Animal, Has Two-Tier Defense Against Cancer Despite a 30-year lifespan that gives ample time for cells to grow cancerous, a small rodent species called a naked mole rat has never been found with tumors of any kind"”and now biologists at the University of Rochester think they know why. The findings, presented in today's issue of The Proceedings of the National Academy of Sciences, show that the mole rat's cells express a gene called p16 that...

After two years of research over five degraded landscapes in the National Park of Sierra Nevada (Granada), scientists have established for the first time that field mice base their diet on holm oak and pine seeds, causing a deterioration of the habitats and an extension of scrubland in the forests.The trees in the forests such as the holm oaks, rowans and pines have unexpected predators which are impeding their expansion over the mountains. In 98.5% of cases it is field mice and other rodents...

Not only the world-famous primeval horse browsed at the shores of the lake in the warm, wet climate prevailing at that time (average annual temperature, 25°C). Around Lake Messel, which emerged in a volcanic crater and was surrounded back then by dense primeval forest, lived early ungulates and rodents; the ancestors of today's birds flew over the cloudy water; insects buzzed through the air; and cold-blooded reptiles basked lazily in the sun. 47 million years ago, Messel was located at...

Changes in the head shape and overall size of rodents has been linked to human population density and climate change, a Chicago researcher said. The size and head shape of rodents has shifted substantially during the last 100 years, with some larger and some smaller, Oliver Pergams, a researcher at the University of Chicago said in a statement released Friday. Pergams studied 1,300 specimen rodents from museums around the world, including Chicago's Field Museum and the Smithsonian Institution...

You probably hadn't noticed -- but the head shape and overall size of rodents has been changing over the past century. A University of Illinois at Chicago ecologist has tied these changes to human population density and climate change.The finding is reported by Oliver Pergams, UIC research assistant professor of biological sciences, in the July 31 issue of PLoS One.Pergams said that such size-and-shape changes in mammals, occurring around the world in less than a century, are quite...

African Pygmy Mouse, Mus minutoides
2012-05-15 07:41:59

The African pygmy mouse (Mus minutoides) can be found in the sub-Saharan areas of Africa. This mouse, perhaps the smallest of all rodents, can also be found living as pets around the world. Being social creatures, African pygmy mice will live in colonies preferably around water in grassy areas. When kept as pets, the mice cannot be left alone. Although the underbelly of the African pygmy mouse is a pale white, the rest of fur is colored reddish orange. The triangular ears, although small,...

Maras like to live in burrows and will occasionally inhabit burrows that already exist from other animals. They are herbivorous. The Patagonian Mara is from the Family Caviidae, which includes cavies, such as their larger relative the capybara, and guinea pigs. Patagonian Maras are closely related to the other member of the...

The Little Swan Island Hutia, Geocapromys thoracatus, was native to Little Swan Island, off north-eastern Honduras in the Caribbean. The ancestors of the species may have been carried to the island from Jamaica, 5,000-7,000 years ago. It may have been a subspecies of the Jamaican hutia (Geocapromys browni). The Little Swan Island Hutia was a slow-moving, guinea pig-like rodent and probably emerged from caves and limestone crevices to forage on bark, small twigs and leaves. It was fairly...

The African Pouched Rat, Cricetomys emini, also known as Emin's Rat, is a large rodent in the muroid super family. It is related to the Gambian Pouched Rat. They are native to Africa and are found along the edges of forests and along the plains. Emin's rats are actually better climbers than their better known Gambian pouch rat cousins. These pouched rats are named for having cheek pouches much like a hamster. The African Pouched Rat has a distinct line of color difference between their...

Chinchillas and their relative's viscachas are small, twilight rodents native to the Andes Mountains in South America. They belong to the family Chinchillidae. Chinchilla fur is considered the softest in the world and is thirty times softer than human hair. Chinchillas must regularly bathe in dust or volcanic ash to remove oil and moisture that gathers in their thick fur. They have the highest fur density of any land animal with more than 20,000 hairs per square cm. Their fur is so dense...
