Death by hyperdisease
It took less than a decade for native rats to become extinct on the Indian Ocean's previously uninhabited Christmas Island once Eurasian black rats jumped ship onto the island at the turn of the 20th century. view more (2008-11-05)
Extinct sabertooth cats were social, found strength in numbers, study shows
The sabertooth cat (Smilodon fatalis), one of the most iconic extinct mammal species, was likely to be a social animal, living and hunting like lions today, according to new scientific research. The species is famous for its extremely long canine teeth, which reached up to seven inches in length... view more (2008-10-31)
The Marine Mammal Center begins new leptospirosis study in California
The Marine Mammal Center is seeing a large number of leptospirosis cases in California sea lions this year and is leading a study to determine when and why the sea lions contract this disease. view more (2008-10-23)
Field Museum provides gold standard for mammal survey
Putting together the Who's Who of bats, bears, beaked whales and all of Earth's other known mammals was a gigantic task ably assisted by a Field Museum scientific team with access to one of the planet's most extensive and diverse mammal collections. view more (2008-10-07)
Researchers document world's mammals in crisis
From majestic African elephants to tiny and often unappreciated rodents, mammals on Earth are in a state of crisis. One in four mammal species on Earth is being pushed to extinction, according to the Global Mammal Assessment, the most comprehensive assessment of the world's mammals. view more (2008-10-06)
Canada's shores saved animals from devastating climate change
The shorelines of ancient Alberta, British Columbia and the Canadian Arctic were an important refuge for some of the world's earliest animals, most of which were wiped out by a mysterious global extinction event some 252 million years ago. view more (2008-10-01)
Long-term study shows effect of climate change on animal diversity
Two species of giraffe, several rhinos and five elephant relatives, along with multitudes of rodents, bush pigs, horses, antelope and apes, once inhabited what is now northern Pakistan. view more (2008-09-23)
Scavenger birds chew the fat
Humans aren't the only ones who like fatty foods - bearded vultures do, too. A study by Antoni Margalida from the Bearded Vulture Study and Protection Group in El Pont de Suert, Spain, has found that the bearded vulture will discard less energy-dense bones and choose only the bones containing the... view more (2008-09-09)
Sky islands: metaphor or misnomer?
The term "sky islands" sounds intriguing, but it may be more lyrical than useful when discussing mammal distributions, according to new research from Eric Waltari of the Sackler Institute of Comparative Genomics at the American Museum of Natural History and Robert Guralnick from the... view more (2008-08-14)
Woolly-Mammoth Gene Study Changes Extinction Theory
A large genetic study of the extinct woolly mammoth has revealed that the species was not one large homogenous group, as scientists previously had assumed, and that it did not have much genetic diversity. view more (2008-06-12)
New study finds most North Pacific humpback whale populations rebounding
The number of humpback whales in the North Pacific Ocean has increased since international and federal protections were enacted in the 1960s and 70s, according to a new study funded primarily by NOAA and conducted by more than 400 whale researchers throughout the Pacific region. view more (2008-05-22)
Cold Spring Harbor Scientists Are Part of Consortium That Sequences Platypus Genome, Unlocking Secrets of Evolution
By any account, the platypus is an odd creature. It's got a broad, rubbery bill that brings to mind a duck-.but it swims more like a beaver-.yet it lays eggs and can inject poisonous venom, like a reptile. view more (2008-05-09)
Platypus Genome Decoded
The curious discovery of the duck-billed, egg-laying, otter-footed, beaver-tailed, venomous platypus in Australia in 1798 convinced British scientists that it must be a hoax. Sketches of its appearance were thought to be impossible. view more (2008-05-08)
Arctic marine mammals on thin ice
The loss of sea ice due to climate change could spell disaster for polar bears and other Arctic marine mammals. The April Special Issue of Ecological Applications examines such potential effects, puts them in historical context, and describes possible conservation measures to mitigate them. view more (2008-04-24)
Researchers to Develop Ocean Sanctuary "Noise Budget" to Identify Sources and Evaluate Potential Impact on Marine Mammals and Fish
Like sentinels at their posts, an array of buoys equipped with underwater microphones and other sensors will be on duty in the Stellwagen Bank National Marine Sanctuary off the coast of Massachusetts for the next 30 months, recording sounds from whales, fish, ships and other sources around the... view more (2008-04-02)
Are wolves the pronghorn's best friend?
As western states debate removing the gray wolf from protection under the Endangered Species Act, a new study by the Wildlife Conservation Society cautions that doing so may result in an unintended decline in another species: the pronghorn, a uniquely North American animal that resembles an African... view more (2008-03-04)
Animal magnetism provides a sense of direction
They may not be on most people's list of most attractive species, but bats definitely have animal magnetism. Researchers from the Universities of Leeds and Princeton have discovered that bats use a magnetic substance in their body called magnetite as an 'internal compass' to help them navigate. view more (2008-02-27)
Amazon corridors far too narrow, warn scientists
Protected forest strips buffering rivers and streams of the Amazon rainforest should be significantly wider than the current legal requirement, according to pioneering new research by scientists at the University of East Anglia (UEA). view more (2008-02-19)
Missing link shows bats flew first, developed echolocation later
The discovery of a remarkably well-preserved fossil representing the most primitive bat species known to date demonstrates that the animals evolved the ability to fly before they could echolocate. view more (2008-02-14)
Adaptive functional evolution of leptin in cold-adaptive pika family
Researchers at the Northwest Institute of Plateau Biology, Chinese Academy of Sciences have put forward the viewpoint for the first time that adaptive functional evolution may occur in the leptin protein of the pika (Ochotona) family, a typical cold-adaptive mammal. view more (2008-01-23)
Marsupial lion tops African lion in fight to death
Pound for pound, Australia's extinct marsupial lion (Thylacoleo carnifex) would have made mince meat of today's African lion (Panthera leo) had the two big hyper-carnivores ever squared off in a fight to the death, according to an Australian scientist. view more (2008-01-17)
Scientists map out potential for restoring California fisher populations
U.S. Forest Service and U.C. Santa Barbara scientists believe they have identified the habitat needs for Pacific fishers, a rare California mammal that is a candidate for reintroduction efforts and listing under the Endangered Species Act. view more (2008-01-14)
When animals evolve on islands, size doesn't matter
A theory explaining the evolution of giant rodents, miniature elephants, and even miniature humans on islands has been called into questions by new research published today in Proceedings of the Royal Society B: Biological Sciences. view more (2007-11-07)
Burrowing mammals dig for a living, but how do they do that?
Next time you see a mole digging in tree-root-filled soil in search of supper, take a moment to ponder the mammal's humerus bones. view more (2007-10-29)
