Yangtze turtles may avoid extinction, but not this year
Darkfrog submitted, created time 2 months 4 weeks (www.nytimes.com)
In the past months, the Changsha and Suzhou zoos came to an agreement, and the the last known female Yangtze giant soft-shell turtle was carefully transported to Suzhou to meet and hopefully mate with what was at the time the only undisputed male of her species. Two more males but no females have since been found. This is one of the most endangered species on the planet.
Herpetologists were hopeful for this high-stakes captive breeding program 
A quarter of mammals face extinction

This article covers one of the most, possibly the most, comprehensive studies of endangered animals in human history. Previous efforts have had to limit themselves to only better-known or better-studied species, but this one covers marine and obscure mammals as well.
"One in four of the world's mammal species is threatened with extinction, according to the first comprehensive survey of this class of animal. Populations are declining in half of all mammal species, with some experiencing an extreme decline. Tasmanian devil (Sarcophilus harrisii) numbers have plummeted by 60%" since 1998

Researchers discover a wild tree shrew that lives on alcoholic nectar. We've known for years that the pen-tailed shrew loves the nectar of the flowering bertram plant, but now I guess we know why...

"Watch out!" It's a simple phrase, but researchers have long debated whether nonhuman primates use something like it. A new study indicates that they do: Even when not threatened themselves, African blue monkeys warn neighbors of nearby predators. However, some skeptics maintain that the animals are acting out of fear, not concern for others

The adaptive function of copulation calls in female primates has been debated for years. One influential idea is that copulation calls are a sexually selected trait, which enables females to advertise their receptive state to males. Male-male competition ensues and females benefit by getting better mating partners and higher quality offspring. We analysed the copulation calling behaviour of wild female chimpanzees (Pan troglodytes schweinfurthii) at Budongo Forest, Uganda, but found no support for the male-male competition hypothesis
Rodent Bones of Contention--When Did Humans Reach New Zealand?

Feisty frog uses a move straight from the comic books

I've said it before; I'll say it again: You would NEVER see this in Nature. In a writeup by Lauren Cahoon, Science compares a rare frog behavior to characters from Marvel Comics.
Science reports that certain African frogs of the Arthroleptidae variety have a very interesting way of repelling attackers. Researchers who picked up live frogs often found themselves scratched and bleeding, as if cut by claws ...which frogs don't have
Global biodiversity slumps 27% in 35 years
sea-maid submitted, created time 7 months 3 weeks (www.newscientist.com)
From this study, the latest data on the global biodiversity of vertebrates shows that it has fallen by almost one-third in the last 35 years. But experts say it may still underestimate the effect humans have had on global species counts.
Ultrasonic frogs show hyperacute phonotaxis to female courtship calls
kavin submitted, created time 7 months 3 weeks (www.ncbi.nlm.nih.gov)
Here the authors show that before ovulation, gravid females of O. tormota emit calls that are distinct from males' advertisement calls, having higher fundamental frequencies and harmonics and shorter call duration. In the field and in a quiet, darkened indoor arena, these female calls evoke vocalizations and extraordinarily precise positive phonotaxis (a localization error of
Climate Change Jeopardizes Koalas

A researcher says koala numbers are threatened because gas saps nutrients from eucalyptus leaves with are the animals' only food source.
CNN-Endangered zebra life caught on GPS
kavin submitted, created time 8 months 2 weeks (edition.cnn.com)
If you were a zebra, how would you spend your days? Daniel Rubenstein and collaborators suggest that the zebras are like grass vacuum cleaners, chip-clipping away at the vegetation as they move. From that, people come to understand that wildlife and livestock are not necessarily antagonistic."No longer are [zebras] necessarily vermin that are viewed negatively by the community," Rubenstein said. "They now have some economic worth."
Web Extra: First Frog without Lungs
jiangyun submitted, created time 8 months 3 weeks (www.sciencenews.org)
Maybe it's incredible. Looks like a frog. Swims like a frog. But doesn't croak. A flattened, brown, aquatic species from Borneo has just become the only frog shown to have no lungs.
Antibiotic Alligator: Promising proteins lurk in reptile blood
jiangyun submitted, created time 8 months 3 weeks (www.sciencenews.org)
Researchers hunting for new antibiotics might get some aid from gator blood. Scientists are zeroing in on snippets of proteins found in American alligator blood that kill a wide range of disease-causing microbes and bacteria, including the formidable MRSA or methicillin-resistant Staphylococcus aureus.
Frogs and alligators swim using flexible lungs
Darkfrog submitted, created time 9 months 3 weeks (sciencenow.sciencemag.org)
Almost any swamp movie shows alligators moving through the water without twitching a muscle. Turns out there is one muscle moving: the gator's diaphragmaticus, which extends lengthwise through its body and pushes stored air to one side of the body or the other, allowing the animal to tilt in the water. I don't wonder why this developed. It's probably easier to convince prey that you're a helpless log if you never move your feet or tail. Frogs do something similar.
And now the crucial question: Do crocodiles do this too and, if so, how do we tell them apart?
Modern Turtles Much Younger Than Thought?
Vincent submitted, created time 9 months 3 weeks (sciencenow.sciencemag.org)
As reptiles go, turtles are old--no question. They evolved before snakes and crocodiles and preceded dinosaurs. But establishing when the common ancestor of modern turtles first appeared has recently become controversial. Now a new fossil is backing the idea that modern turtles evolved more recently than previously thought.
