As concerns about the effects of global warming continue to mount, a new study published in the December issue of Physiological and Biochemical Zoology finds that an increase in average temperature of only two degrees Celsius could have a devastating effect on populations of Australia's iconic kangaroos.

Streams that once sang with the croaks, chirps and ribbits of dozens of frog species have gone silent. They’re victims of a fungus that’s decimating amphibian populations worldwide. [...more]
From majestic African elephants to tiny and often unappreciated rodents, mammals on Earth are in a state of crisis. One in four mammal species on Earth is being pushed to extinction, according to the Global Mammal Assessment, the most comprehensive assessment of the world's mammals. [...more]
Devastating declines of amphibian species around the world are a sign of a biodiversity disaster larger than just frogs, salamanders and their ilk, according to researchers from the University of California, Berkeley. [...more]
Many birds are arriving earlier each spring as temperatures warm along the East Coast of the United States. However, the farther those birds journey, the less likely they are to keep pace with the rapidly changing climate. [...more]
According to the latest research, species around the world are going extinct faster that previously thought, at a rate not seen since the extinction of the dinosaurs. The Living Planet index which was released today shows that due to destructive human activity, the diversity of all life on earth has decreased by over 30%, nearly a third in fact in the past thirty-five years. [...more]
A new report released by Oceana today concludes that more than 80 percent of the world's fisheries cannot withstand increased fishing activity and only 17 percent of the world's fisheries should be considered capable of any growth in catch at all. Too Few Fish: A Regional Assessment of the World's Fisheries shows there is very little room for further expansion of global fishing efforts. [...more]
The first study to determine the global threat status of 21 species of wide-ranging oceanic pelagic sharks and rays reveals serious overfishing and recommends key steps that governments can take to safeguard populations. These findings and recommendations for action are published in the latest edition of Aquatic Conservation: Marine and Freshwater Ecosystems. [...more]
Fewer caribou calves are being born and more of them are dying in West Greenland as a result of a warming climate, according to Eric Post, a Penn State associate professor of biology. Post, who believes that caribou may serve as an indicator species for climate changes including global warming, based his conclusions on data showing that the timing of peak food availability no longer corresponds to the timing of caribou births. [...more]
The loss of sea ice due to climate change could spell disaster for polar bears and other Arctic marine mammals. The April Special Issue of Ecological Applications examines such potential effects, puts them in historical context, and describes possible conservation measures to mitigate them. The assessment reflects the latest thinking of experts representing multiple scientific disciplines. [...more]
