As the climate warms, plant species that prefer a colder environment are disappearing from the mountain ranges of Southern Europe. Since many of these species have small distribution areas, they are now threatened with extinction, according to two new studies from European researchers.
"These species have migrated upwards, but sooner or later the mountain reaches its summit," said researcher and biologist Ulf Molau at Sweden’s University of Gothenburg. "Many alpine plant species are disappearing from mountain ranges in Southern Europe, and for some of them - those that are only found in a single mountain range - the outlook is extremely bleak."
Over a period of 10 years, researchers around Europe have gathered samples from 13 different mountain regions.
Using digital technology and intensive on-site field work, they have been able to study a grid pattern of square meters, selected on different high mountain summits, from the treeline up to the highest peaks.
The digital photographs provide a detailed picture of which species have disappeared between 2001 and the present day.
"Every research square is digitally photographed so that we can find our way back to the exact same position after 10 years or more, with centimeter precision," said Professor Molau. "By rolling out an analysis network, small 10 x 10 cm squares can be re-mapped."
Today, the researchers are able to observe that species are migrating upwards and that the variety of species in Southern European mountain regions has declined during the 10 years in which samples have been taken.
"This finding confirms the hypothesis that a rise in temperatures drives Alpine flora to migrate upwards. As a result, rival species are threatened by competitors, which are migrating to higher altitudes. These changes pose a threat to high-mountain ecosystems in the long and medium term," the authors state.

Witness more species loss.
African Parks Are Losing Vultures
Some species of vultures have become increasingly threatened in recent years due to habitat loss and toxicity of the animals they depend upon for food. Scientists recently discovered that vultures in East Africa are no exception. New tallies of the scavengers show that even populations inside protected areas are under intense pressure for survival.
Yahoo! Profits from the Slaughter of Whales
Although Yahoo! has banned the sale of whale products on all its other sites, its Japanese subsidiary – Yahoo! Japan – continues to sell whale products. That means Yahoo! – through its 34% interest in Yahoo! Japan – profits from the illegal slaughter of whales.

Incredible story of the first cloned endangered species. An endangered Asian ox called a gaur was born to a domestic cow. Even more mind-blowing is that the science team used an 8-year old frozen cell for the experiment, proof that cloning can be successful for species management.
Cloning and Conservation
On January 8, 2001, a healthy baby gaur—a large ox-like animal whose populations are now threatened throughout much of their native range from India to Southeast Asia—was born. In Sioux Center, Iowa. To a cow named Bessie. The baby bull, named Noah, was a clone: the first clone of a threatened species, and the first animal ever created by inserting the DNA of one species into the egg of another.

Grossness Untamed by National Geographic looks pretty grossapocalypse. I presume it’s a tv show - Any of y’all seen it??
I can’t stop staring at this beautiful and stunning snake. What also blows my mind is it wasn’t “taught” by parents to curl into this hunting position, it just “knows.” We live on an absolutely amazing planet.

Defenders of Wildlife recently released a new report entitled Harnessing Nature: The Ecosystem Approach to Climate Change Preparedness, which summarizes the benefits of strengthening and enhancing green infrastructure and offers case studies of communities around the country that are already harnessing nature to lessen the impacts of floods, storms, droughts, wildfires and rising sea levels. The report also offers recommendations to help agencies and communities incorporate ecosystem-based measures into their climate-change adaptation plans.
Trouble in paradise. The Maldives islands are among the most beautiful places on earth. The islands are considered by some to be ground zero for the impacts of sea level rise, and the country’s president has been a strong advocate for climate adaptation measures.
However, the islands have a dirty secret - it’s been dumping its trash and toxic chemicals into the ocean. The BBC cracks the case wide open in this sickening video report, “Apocalyptic island of waste in the Maldives.”
