    By the 1990s the northern bald ibis was not only long gone from Europe but also critically endangered around the world, namely in the Middle East and North Africa, where it once flourished. In the 1950s, Turkey used DDT intensively, killing many hundreds of birds while also interfering with their reproduction. Conservationists caught more than 40 of the remaining wild birds in the ‘70s and ‘80s, preventing them from migrating but allowing them to breed on site. The hatchlings did well, but the wild flock continued to decline and was declared extinct in 1990. Their migration tradition died with them. Without experienced migrators to show them the way, the descendants of the captured birds remained in Turkey, cared for by humans, unaware of where their ancestors had spent their winters.

    In the meantime, zoos figured out how to breed the northern bald ibis using descendants of a North African population. There were soon more than zoos could handle. Some conservationists experimented with releasing them into the wild to form colonies, but the young birds didn’t cohere into a group and instead wandered off.

    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.

    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.

    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.

    This vascular plant Red List for England presents for the first time a comprehensive and objective assessment of threat, using globally recognised IUCN categories and criteria, for over 1,800 native and archaeophyte species found in the region.

    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.

    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.
