Monarch Butterflies need Endangered Species Act protection
As monarch butterflies are beginning their epic migration from Canada and the U.S. to Mexico for the winter, concerns about the drastic rate at which they're disappearing from the landscape have led environmental and health organizations to petition the government for federal protection. This week, the Center for Biological Diversity, Center for Food Safety, Xerces Society and monarch scientist Dr. Lincoln Brower filed a legal petition with the U.S. Fish and Wildlife Service seeking protection for monarchs under the Endangered Species Act. >> Read the Full Article
Yawn Contagion in Wolves
A yawn is defined as a reflex act of opening one's mouth and inhaling deeply. We yawn most often when we are tired or when we're bored. But we also always yawn when we see someone else doing it. Why? People say we can't help it - it's contagious! But what really triggers this involuntary tendency? According to studies, yawning when others do is a sign of empathy and a form of social bonding. And believe it or not, we're not the only species to exhibit these contagious behaviors. A new study published today in the journal PLOS ONE shows that wolves may also be susceptible to yawn contagion. >> Read the Full Article
Dams vs. Rivers
A new 'State of the World's Rivers' database shows how the world's rivers have been impoverished by dams and their ecosystems devastated - and provides a valuable resource to help save river basins that remain in good health. International Rivers has launched 'The State of the World's Rivers', an interactive online database that illustrates the role that dams have played in impoverishing the health of the world's river basins. >> Read the Full Article
How Geckos can walk on the ceiling
Ever wonder how lizards like Geckos can walk up walls and even across the ceiling? Is it sticky feet, anti-gravity, or what? Researchers at Oregon State University have developed a model that explains how geckos, as well as spiders and some insects, can run up and down walls, cling to ceilings, and seemingly defy gravity with such effortless grace. This ability, outlined today in the Journal of Applied Physics, is a remarkable mechanism in the toes of geckos that uses tiny, branched hairs called "seta" that can instantly turn their stickiness on and off, and even "unstick" their feet without using any energy. >> Read the Full Article
Electricity from silk cocoons?
Researchers in India say they have developed a prototype of an energy-harvesting device from the cocoons of a domesticated species of silk moth. They hope to put the technology to practical use while also tackling waste materials from the silk processing industry. >> Read the Full Article
Do we really need to kill wild animals that attack or threaten humans?
In Italy, a man foraging for mushrooms was attacked when he happened upon a mother bear and her cubs. Part of a reintroduction and conservation program in Italy's northern Dolomites, the bear, named Daniza, was ordered to be captured and possibly killed. This has sparked social media outrage, prompting those on twitter to hashtag #iostocondanzia (I'm with Danzia). The outrage stems from a revelation that when mauling victim Daniele Maturi happened upon the bear, he did not immediately leave, but rather hid behind a tree to watch him. It is said the bear only charged when it spotted him watching from behind a tree (like a predator would do, thus provoking the bear). >> Read the Full Article
Grizzly Bears in the North Cascades
The National Park Service this week took an important step toward recovering grizzly bears in the North Cascades in Washington state. The agency says it is beginning a three-year process to analyze options for boosting grizzly bear populations in the area, including the possibility of translocating bears and developing a viable population. "We're happy to see the Park Service begin the long-overdue conversation about bringing grizzly bears back to the North Cascades," said Noah Greenwald, endangered species director with the Center for Biological Diversity. "Grizzlies have lost more than 95 percent of their historic habitat in the lower 48 states so we welcome any step that brings them closer to returning to some of their ancestral homes." >> Read the Full Article
Turning Jellyfish into Sustainable Medical Products
In a United Nations report released in May, scientists worldwide were called upon to join the war on jellyfish. According to the report, jellyfish have overwhelmed the marine ecosystem as a result of the overfishing of more competitive species, consuming fish eggs and larvae of weaker specimens and creating what the report called a "vicious cycle." So how can this cycle be stopped? >> Read the Full Article
Arctic insects and spiders can survive colder temperatures than thought
Arctic bugs can survive in frozen ground as cold as -27Â°C, scientists have revealed. It is the first time higher-order invertebrates such as spiders, flies and beetles have been found coping in direct exposure to such cold temperatures. Previous lows were between just -5Â°C and a little below -10Â°C. The research, published in the Journal of Thermal Biology, suggests they may be more resilient to climate change than first feared. >> Read the Full Article
Africa Faces Unsustainable Levels of Ivory Poaching
When it comes to illegal wildlife trade, one thing has always puzzled me... Why is the demand for ivory so high? While I may not come across the black-market demands or understand the cultural or historical needs for these rare animal teeth, one thing is easy to see - populations of the African elephant are declining. >> Read the Full Article
