Throughout the state, climate change is intensifying storm surges and thawing the permafrost—land that previously remained frozen throughout the year. Parts of highways are sinking. Trees around Fairbanks have slipped to such rakish angles that they have become known as drunken forests.
But it’s not hard to see why the Yukon-Kuskokwim Delta, a watershed the size of Britain, is especially vulnerable. Approaching from the air, it’s difficult to determine whether this region is a landmass with many lakes or a body of water with many islands. The Yup’ik never intended to live here year-round: They were a nomadic people forced into settlements by missionaries and the government. The villages where the Yup’ik now live year-round were once their summer fishing and hunting grounds.September 26, 2014 at 7:32 pm #14962

Con Slobodchikoff is an animal behaviorist and conservation biologist. He is a professor at Northern Arizona University, where he studies referential communication, using prairie dogs as a model species. Much of his recent research has Cons-Portrait-2012shown a complex communicative ability of the Gunnison prairie dog alarm calls. In early 2008 he formed the Animal Language Institute, to create a place where people can find and share research in animal communication.September 30, 2014 at 11:08 am #14991
The world populations of fish, birds, mammals, amphibians and reptiles fell overall by 52 percent between 1970 and 2010, far faster than previously thought, the World Wildlife Fund said on Tuesday.
The conservation group’s Living Planet Report, published every two years, said humankind’s demands were now 50 percent more than nature can bear, with trees being felled, groundwater pumped and carbon dioxide emitted faster than Earth can recover.October 1, 2014 at 12:40 pm #15013

In 1995, wolves were re-introduced into the Yellowstone National Park, after being wolf-free for 70 years. What naturalists and biologist never imagined, was that the most remarkable thing would take place. Mother Nature knows what she’s doing if we just leave her alone.October 22, 2014 at 1:12 am #15092November 19, 2014 at 3:58 pm #15186November 19, 2014 at 4:01 pm #15187December 14, 2014 at 10:12 pm #15303January 21, 2015 at 1:29 am #15463
Researchers eavesdropping on wild chimpanzees have determined that the primates communicate about at least two things: their favourite fruits and the trees where these fruits can be found.
Of particular interest to the chimps is the size of the trees bearing these fruits – the chimps yell out that information, according to a new study published in the journal Animal Behaviour.
The study is the first to find that information about tree size and available fruit amounts are included in chimp calls, in addition to assessments about food quality.
