A study on the effect of global warming on African ape survival suggests that a warming climate may cause apes to run 'out of time'. The research, published July 22 in Journal of Biogeography, reveals that rising temperatures and changes in rainfall patterns have strong effects on ape behavior, distribution and survival, pushing them even further to the brink of extinction. The researchers, from Roehampton University, Bournemouth University and the University of Oxford used data from 20...

Incidence of a lethal infectious disease moves at a rate of 30 kilometers per year A killer has been caught in the act: the first before-and-after view of an infectious disease that led to an amphibian die-off has been released by the scientists who tracked it. The results are published this week in the journal Proceedings of the National Academy of Sciences (PNAS). Like a wave, incidence of the fungal disease that wipes out Central American frogs--chytridiomycosis--advances through the...

Since about 1900, when tiger records were first kept, their numbers are the lowest they have ever been, with conservationists warning that the world has limited time to save the species. The World Wildlife Fund announced Saturday that the wild tiger population has now fallen to about 3,200, down from an estimated 100,000 more than a century ago. The big cat species could soon become extinct unless urgent action is taken to prevent further hunting and loss of habitat, experts are warning....

Faced with threats such as habitat loss and climate change, thousands of rare flowering plant species worldwide may become extinct before scientists can even discover them, according to a paper published today by a trio of American and British researchers in the journal Proceedings of the Royal Society B. "Scientists have estimated that, overall, there could be between 5 million and 50 million species, but fewer than 2 million of these species have been discovered to date," says lead author...

A new analysis of the extinction of woolly mammoths and other large mammals more than 10,000 years ago suggests that they may have fallen victim to the same type of "trophic cascade" of ecosystem disruption that scientists say is being caused today by the global decline of predators such as wolves, cougars, and sharks. In each case the cascading events were originally begun by human disruption of ecosystems, a new study concludes, but around 15,000 years ago the problem was not the loss of a...

Hurricanes, wildfires and influxes of pollutants create disturbances that can put ecological systems under extreme stress. Ecologists had believed that at times like these, competition between species becomes less important as all struggle to survive. But a new laboratory study of microscopic organisms subjected to varying degrees of acoustic disturbance now challenges that assumption "“ and could lead ecologists to reconsider how organisms compete during challenging times. "The...

Home to jaguars, harpy eagles and red-eyed tree frogs, tropical forests support some of the rarest species on the planet and are the most biodiverse ecosystems on land. Understanding why some species are common while others are exceedingly rare has been a challenge in these mega-diverse forests. New results from a massive study at the Smithsonian Tropical Research Institute show that interactions among community members play an important role in determining which organisms thrive. "Based on...

Researchers at Yale University have found that the risk of extinction for mountain birds due to global warming is greatest for species that occupy a narrow range of altitude. In fact, a species' vertical distribution is a better predictor of extinction risk than the extent of temperature change they experience, the researchers report in the June 9 issue of the Proceedings of the Royal Society B: Biological Sciences. "Birds allow us to do the first global assessment of the health of a whole...

People could help to prevent species of birds from becoming extinct by recording sightings of all kinds of birds online, including common species, according to a new study published June 1 in PLoS Biology. The researchers behind the study, from Imperial College London, are urging the public to become 'citizen scientists' to help prevent today's common bird species from becoming threatened tomorrow. To establish whether a certain species of bird is at risk of becoming endangered, so that they...

The balance of biodiversity within North American small-mammal communities is so out of whack from the last episode of global warming about 12,000 years ago that the current climate change could push them past a tipping point, with repercussions up and down the food chain, say Stanford biologists. The evidence lies in fossils spanning the last 20,000 years that the researchers excavated from a cave in Northern California. What they found is that although the small mammals in the area suffered...

The Waitoreke is a cryptid from New Zealand described as being otter-like. Its name derived from “Wai” is a Maori word for water. The rest of the word has different translations, but the common one is “toreke,” which means to disappear. Together the name could translate into “disappears into water” or another translation is a “disappearing water specter.” The usual description is a small otter-like creature about the size of a cat. It has brownish short fur and short...

Red Rail, Aphanapteryx bonasia
2013-10-02 13:35:50

The Red Rail (Aphanapteryx bonasia) is an extinct and flightless rail. It was native to the Mascarene island of Mauritius, east of Madagascar within the Indian Ocean. It had a close relative on Rodrigues Island, the likewise extinct Rodrigues Rail, with which it’s sometimes considered congeneric. Its relationship with other rail isn’t clear. Rails frequently evolve flightlessness when adapting to isolated islands. It was slightly larger than a chicken and had reddish and hair-like...

Panthera leo spelaea

Commonly known as the Eurasian cave lion or the European cave lion, Panthera leo spelaea is an extinct subspecies of lion. It is thought to have lived during the Pleistocene epoch, and may have lived in the Balkans in southeastern Europe until 2,000 years ago. The range of this cave lion would have included northwestern North America, Asia, and areas of Europe and would have extended from Germany, Spain, and Great Britain to the Yukon Territory. Its range also extended from Turkistan to...

The short-faced bear is an extinct genus of bears that was native to North America during the Pleistoscene era. Other common names include Arctodus and the bulldog bear. There are two subspecies of the short-faced bear, and one of them, Aroctodus simus, is thought to have been the largest terrestrial mammal on earth. Placed into a group of bears known as running bears or the tremarctine bears, this genus was found in Europe and the Americas. The earliest member of the tremarchtine group,...

The American lion (Panthera leo atrox or P. atrox) is also known as the North American lion, American cave lion, or Naegele’s giant jaguar. It is an extinct species that was native to North America and the northwestern parts of South America during the Pleistocene era. It lived up to eleven thousand years ago. During the last interglacial period in North America (the Sangamonian Stage), the American lion’s range included the Americas south of Alaska. The earliest fossils of these big cats...
