A new genetic study by a team of Cuban and American researchers confirms that American crocodiles are hybridizing with wild populations of critically endangered Cuban crocodiles, which may cause a population decline of this species found only in the Cuban Archipelago. Cuban crocodiles and American crocodiles have been confirmed to interbreed in captivity and were suspected to hybridize in the wild. This is the first genetic study that confirms wild hybridization. The study, which appears in...

The world's oceans are declining much faster than previously believed, a consortium of ocean experts warned on Monday. Ocean life is "at high risk of entering a phase of extinction of marine species unprecedented in human history," the scientists said in their report, blaming the problem on pollution, overfishing and other man-made causes that are acting simultaneously in ways not seen before. The panel of 27 of the world's top ocean experts said these conditions are pushing the oceans to the...

A species of antelope that is possibly the source for the legend of the unicorn has been successfully reintroduced into its native habitat after having been hunted to all but extinction, reports the AFP news agency. The oryx comes by unicorn legend because when viewed in profile the two slender horns can appear to be a single horn. Oryx leucoryx, a desert antelope native to the Arabian peninsula, has long been on the endangered species list after being effectively extinct in the wild....

A new study provides support for Darwin's hypothesis that the struggle for existence is stronger between more closely related species than those distantly related. While ecologists generally accept the premise, this new study contains the strongest direct experimental evidence yet to support its validity. "We found that species extinction occurred more frequently and more rapidly between species of microorganisms that were more closely related, providing strong support for Darwin's theory,...

Smithsonian scientists have confirmed that chytridiomycosis, a rapidly spreading amphibian disease, has reached a site near Panama's Darien region. This was the last area in the entire mountainous neotropics to be free of the disease. This is troubling news for the Panama Amphibian Rescue and Conservation Project, a consortium of nine U.S. and Panamanian institutions that aims to rescue 20 species of frogs in imminent danger of extinction. Chytridiomycosis has been linked to dramatic...

A team of 21 researchers from 11 nations, including professor Robert "JJ" Orth of the Virginia Institute of Marine Science, has completed the first-ever study of the risk of extinction for individual seagrass species around the world. The 4-year study, requested by the International Union for the Conservation of Nature (IUCN), shows that 10 of the 72 known seagrass species (14%) are at an elevated risk of extinction, while 3 species qualify as endangered. The authors caution that loss of...

For more than 40 years, the International Union for Conservation of Nature (IUCN) has published the Red List of Threatened Species describing the conservation status of various species of animals. They are now also including plants in their lists and the picture they present is dramatic. According to recent estimates, around 20 per cent of flowering plants are currently at risk of extinction "“ though the exact number is unknown since such a small proportion of plant species has even...

A projected wave of extinctions of plant and animal species this century may have been overestimated because the most widely used scientific method can exaggerate losses by more than 160 percent, according to a study published Wednesday in the journal Nature. The scientists said that habitat destruction by humans is driving animal and plant species toward extinction at just half the pace as previously believed. They attribute the overestimation to flaws in the most popular scientific method,...

However, researchers say, global extinction crisis remains very serious The most widely used methods for calculating species extinction rates are "fundamentally flawed" and overestimate extinction rates by as much as 160 percent, life scientists report May 19 in the journal Nature. However, while the problem of species extinction caused by habitat loss is not as dire as many conservationists and scientists had believed, the global extinction crisis is real, says Stephen Hubbell, a...

Waitoreke

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...

Short-faced Bear, Arctodus simus
2012-04-27 19:45:45

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,...

2012-04-26 06:05:05

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...
