Latest Extinction Stories
Both migration and evolution played a role in the adaptation of shootingstars to warmer temperatures after the last ice age.
The phrase "invasive plant species" typically evokes negative images such as broad swaths of kudzu smothered trees along the highway or purple loosestrife taking over wetlands and clogging waterwaysâ€”and as such, invasive plants are largely viewed as major threats to native biodiversity.
A new index has been developed to help conservationists better understand how close species are to extinction.
The "color" of our environment is becoming "bluer", a change that could have important implications for animals' risk of becoming extinct, ecologists have found.
Conservationists may need to change their approach to protecting animals and plants from extinction if they are to successfully shield key species and habitats from the effects of global climate change.
Scientists warned on Wednesday that 45 rare species of wallaby, bandicoot and other Australian animals could become extinct within 20 years unless urgent action is taken to control introduced predators and other threats.
A University of York scientist is proposing a radical programme of 'assisted colonisation' to save species endangered by climate change.
According to classical ecology, when two species compete for the same resource, eventually the more successful species will win out while the other will go extinct.
A tropical frog â€“ the only one of its kind in the world â€“ is providing conservationists with exclusive insights into the genetic make-up of its closest endangered relatives.
Paleobiologists at the University of California at Berkeley are studying the state of biodiversity today using the worldâ€™s mammal species as a barometer.
The Hawaiian Rail (Porzana sandwichensis), known also as the Hawaiian Crake or the Hawaiian Spotted Rail, was a rather enigmatic species of minuscule rail that resided on Big Island of Hawaii, but is currently extinct. A dark form and a lighter form are known. There is considerable confusion by the existence of two distinct forms. While it can’t be completely excluded that early specimens were collected on another island, only O’ahu and Kaua’I seem plausible given the history of...
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...
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...
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,...
