Gray Wolf Sighted at Grand Canyon, Offers Hope for Species
November 4, 2014 07:55 AM - Alicia Graef, Care2

Several recent sightings of what’s believed to be a gray wolf at the Grand Canyon in Arizona have wolf advocates hopeful that its presence, which marks the first time one has been seen in the state in 70 years, is yet another a sign of recovery for this iconic species. The lone wolf in question was first spotted in early October by visitors at the Kaibab National Forest north of the Grand Canyon National Park and described as a wolf-like animal, but photos made public by the Center for Biological Diversity – in an attempt to ensure it wasn’t mistaken for a coyote and killed – have led wildlife and park officials to believe it’s a gray wolf.

The Spotted Lanternfly, colorful invader
November 4, 2014 06:03 AM - Bill Chappell, NPR

The spotted lanternfly has officially arrived in the U.S., and leaders in Pennsylvania are hoping it won't be staying long. The invasive pest poses a threat to fruit orchards and grape vines, along with forests and the timber industry. It was detected in Berks County, northwest of Philadelphia.

"Berks County is the front line in the war against Spotted Lanternfly," Agriculture Secretary George Greig said in a news release. "We are taking every measure possible to learn more, educate the public and ourselves and eliminate this threat to agriculture."

The complicated relationship between ice sheets and climate
November 4, 2014 05:48 AM - University of Bristol

Heinrich events, in which large masses of icebergs rapidly broke free from ice sheets during the last ice age, are thought to have influenced global climate by interrupting ocean circulation patterns with a large influx of freshwater. However, new research from the University of Bristol suggests the variations in the height of the ice sheet that happen in these events might also influence global climate. 

In a study published today in PNAS, Dr William Roberts of Bristol’s School of Geographical Sciences and colleagues use computer models to simulate a Heinrich event in Hudson Bay, Canada, adjusting the models to consider freshwater influx only, changing ice sheet height only or both factors together. 

Canadian bats facing bleak future
October 29, 2014 06:54 AM - , Care2

With Halloween just days away, you’re undoubtedly seeing bat images everywhere, which is kind of perfect since it’s also National Bat Week. Too bad that in the real world, bats are suffering, sick and endangered, while governments can’t get their acts together to save bats from a truly monstrous disease: white-nose syndrome (WNS). Instead of fearing bats this holiday, we should be scared of a world without them.

Care2′s Alicia Graef let us know about the American bats that urgently need federal protection: the northern long-eared bat was hit hard by WNS. Our government hasn’t done anything to stop it, but that doesn’t mean that the disease will stop. After first appearing in New York in 2006, WNS has spread to our neighbors in Canada since 2010, and it’s devastating new bat species in its wake, like a real zombie apocalypse.

"Shrinking goats" another indicator that climate change affects animal size
October 29, 2014 06:36 AM - Durham University

Alpine goats appear to be shrinking in size as they react to changes in climate, according to new research from Durham University. The researchers studied the impacts of changes in temperature on the body size of Alpine Chamois, a species of mountain goat, over the past 30 years.  To their surprise, they discovered that young Chamois now weigh about 25 per cent less than animals of the same age in the 1980s.

Adélie penguin chick weights correlated to temperatures
October 28, 2014 01:11 PM - University of Delaware, via ScienceDaily.

Oceanographers have reported a connection between local weather conditions and the weight of Adélie penguin chicks. Adélie penguins are an indigenous species of the West Antarctic Peninsula (WAP), one of the most rapidly warming areas on Earth. Since 1950, the average annual temperature in the Antarctic Peninsula has increased 2 degrees Celsius on average, and 6 degrees Celsius during winter.

As the WAP climate warms, it is changing from a dry, polar system to a warmer, sub-polar system with more rain.

Using Microscopic Bugs to Save the Bees
October 27, 2014 02:49 PM - Brigham Young University

For decades, honeybees have been battling a deadly disease that kills off their babies (larvae) and leads to hive collapse. It’s called American Foulbrood and its effects are so devastating and infectious, it often requires infected hives to be burned to the ground. Treating Foulbrood is complicated because the disease can evolve to resist antibiotics and other chemical treatments. Losing entire hives not only disrupts the honey industry, but reduces the number of bees for pollinating plants. Now an undergraduate student at BYU, funded by ORCA grants, has produced a natural way to eliminate the scourge, and it’s working: Using tiny killer bugs known as phages to protect baby bees from infection.

Can the corridors under high-tension lines be important opportunities for conservation?
October 17, 2014 08:06 AM - richard conniff, Yale Environment360

Often mowed and doused with herbicides, power transmission lines have long been a bane for environmentalists. But that’s changing, as some utilities are starting to manage these areas as potentially valuable corridors for threatened wildlife. Nobody loves electrical power transmission lines. They typically bulldoze across the countryside like a clearcut, 150 feet wide and scores or hundreds integrated vegetation management in right-of-way scores or hundreds of miles long, in a straight line that defies everything we know about nature. They’re commonly criticized for fragmenting forests and other natural habitats and for causing collisions and electrocutions for some birds. Power lines also have raised the specter, in the minds of anxious neighbors, of illnesses induced by electromagnetic fields. So it's a little startling to hear wildlife biologists proposing that properly managed transmission lines, and even natural gas and oil pipeline rights-of-way, could be the last best hope for many birds, pollinators, and other species that are otherwise dramatically declining.

How Offshore Wind Farms Affect Marine Species
October 17, 2014 06:07 AM - University of Maryland Center for Environmental Science

Offshore wind power is a valuable source of renewable energy that can help reduce carbon emissions. Technological advances are allowing higher capacity turbines to be installed in deeper water, but there is still much unknown about the effects on the environment. In a recent paper, University of Maryland Center for Environmental Science researcher Helen Bailey and colleagues review the potential impacts of offshore wind developments on marine species and make recommendations for future monitoring and assessment as interest in offshore wind energy grows around the world.
