A bizarre New Zealand bat that is as much at home walking four-legged on the ground as winging through the air had an Australian ancestor 20 million years ago with the same rare ability, a new study has found.The discovery overturns a long-held held view that the agile walking and climbing skills of the lesser short-tailed bat - Mystacina tuberculata "“ evolved in the absence of any ground-dwelling mammal competitors or predators, says an international team of researchers led by Dr...

Mammals and many species of birds and fish are among evolution's "winners," while crocodiles, alligators and a reptile cousin of snakes known as the tuatara are among the losers, according to new research by UCLA scientists and colleagues."Our results indicate that mammals are special," said Michael Alfaro, a UCLA assistant professor of ecology and evolutionary biology and lead author of the research.The study, published July 24 in the early online edition of Proceedings of the National...

The Chinese have an incredible appetite for the pest-eating pangolins of Southeast Asia - to the point of driving them to endangerment. Activists are now urging the government to do more to ensure their protection. Wildlife trade monitoring group TRAFFIC said in a report, "Due to continual demand and the decreasing Chinese wild population, in the past few years pangolin smuggling from Southeast Asia has resulted in great declines in these producing countries' wild populations." The name...

Charles Darwin and his contemporaries postulated that food consumption in birds and mammals was limited by resource levels, that is, animals would eat as much as they could while food was plentiful and produce as many offspring as this would allow them to. However, recent research has shown that, even when food is abundant, energy intake reaches a limit, even in animals with high nutrient demands, such as lactating females. Scientists at the Research Institute of Wildlife Ecology in Vienna...

An aquatic lifestyle imposes serious demands for the organism, and this is true even for the tiniest molecules that form our body. When the ancestors of present marine mammals initiated their return to the oceans, their physiology had to adapt radically to the new medium. Dr. Michael Berenbrink and his colleagues at Liverpool University have been studying how myoglobin, the molecule responsible for delivering oxygen to the muscles during locomotion, has been modified in seals and whales to...

A new study has found that as the climate continues to get warmer, the rate of molecular evolution in mammals could speed up as they attempt to regulate their body temperature. A study of the same species in different climates found that the DNA of those living in warmer conditions were changing at a faster rate, researchers told BBC News. According to the study published in the Proceedings of the Royal Society B, lead author Len Gillman from Auckland University of Technology and colleagues...

A Wildlife Conservation Society research intern working in Papua New Guinea has completed the first study of a rare egg-laying mammal. The study of the long-beaked echidna in Papua New Guinea's Crater Mountain Wildlife Management Area was conducted by Muse Opiang, now of the Papua New Guinea Institute of Biological Research. It took several years to remotely track the porcupine-sized mammals and record their dens and other signs, WCS officials said. The study chronicles the first solid data...

U.S. scientists have determined how high arctic mammals lived about 54 million years ago in a study said to be important in view of Earth's climate change. University of Colorado-Boulder researchers said ancestors of tapirs and ancient cousins of rhinos living above the Arctic Circle 53 million years ago endured six months of darkness each year in a mild climate that featured lush, swampy forests. Assistant Professor Jaelyn Eberle, who led the researchers, said the study shows several...

In 1996, an international team of scientists led by the University of Zaragoza (UNIZAR) started to carry out a paleontological survey in the cave of El Mir³n. Since then they have focused on analysing the fossil remains of the bones and teeth of small vertebrates that lived in the Cantabrian region over the past 41,000 years, at the end of the Quaternary. The richness, great diversity and good conservation status of the fossils have enabled the researchers to carry out a paleoclimatic...

A new University of Florida study shows mammals change their dietary niches based on climate-driven environmental changes, contradicting a common assumption that species maintain their niches despite global warming. Led by Florida Museum of Natural History vertebrate paleontologist Larisa DeSantis, researchers examined fossil teeth from mammals at two sites representing different climates in Florida: a glacial period about 1.9 million years ago and a warmer, interglacial period about 1.3...

Echidna, Tachyglossidae
2014-06-19 07:53:10

Tachyglossidae is a family that holds eight species of echidnas, also known as spiny anteaters, four of which are known only from fossils. The remaining four species, which include the platypus, can only be found in New Guinea and Australia. They prefer to reside in wooded areas and can be found under piles of vegetation, roots, and occasionally inside the burrows of other animals. This family is named after the "Mother of All Monsters" in Greek mythology, although the two do not resemble...

The Aardvark, Orycteropus afer, sometimes called the "˜antbear', is a medium-sized mammal native to Africa. It lives south of the Sahara desert where there is suitable habitat for them to live. It prefers savannas, grasslands, woodlands and bush. They are not found in deserts but are found in areas where there is a good supply of ants and termites. The most distinctive characteristic of the Aardvark is their teeth. Instead of having a pulp cavity, they have a number of thin tubes of...

The European Mole, Talpa europaea, is a mammal of the order Soricomorpha. This mole lives in an underground tunnel system, which it constantly extends. It uses these tunnels to hunt its prey. Under normal conditions the displaced earth is pushed to the surface, resulting in the characteristic "mole hills". It has a cylindrical body and is around 5 1/4 inches (12 cm) long. Females are typically smaller than males. The eyes are small, and hidden behind fur. Its ear is just a small ridge...

The platypus is a semi-aquatic endemic to eastern Australia and Tasmania. Together with the four species of echidna, it is one of the five species of monotremes, the only mammals that lay eggs instead of giving birth to live young. It is the sole living representative of its family and genus, though a number of related species have been found in the fossil record. The unique appearance of this egg-laying, duck-billed mammal baffled naturalists when it was first discovered, with some...
