Although northern long-eared bat populations have declined by 90 percent in their core range, the U.S. Fish and Wildlife Service today said it will not protect any of its critical habitat, saying it would not be “prudent” for the species. Under the Endangered Species Act, the government can opt not to designate critical habitat if there is factual evidence that a species would be placed at greater risk of extinction from poachers, collectors or vandals. But in the case of the northern long-eared bat, which is listed as “threatened” under the Endangered Species Act, there is almost no evidence that the species is at risk from these types of threats. Instead its dramatic decline has been driven mostly by disease and habitat loss.  

“This is a terrible turn of events for the northern long-eared bat,” said Tanya Sanerib, an attorney at the Center for Biological Diversity. “If you don’t protect the places endangered species live, it becomes that much harder to save them. This is yet another instance where the Fish and Wildlife Service has gone out of its way to appease special interests rather than protecting our most vulnerable animals.”

It was 30 years ago that a meltdown at the V. I. Lenin Nuclear Power Station in the former Soviet Union released radioactive contaminants into the surroundings in northern Ukraine. Airborne contamination from what is now generally termed the Chernobyl disaster spread well beyond the immediate environs of the power plant, and a roughly 1000-square-mile region in Ukraine, Belarus and Russia remains cordoned off, an exclusion zone where human habitation is forbidden.

The radiation spill was a disaster for the environment and its biological inhabitants, but it also created a unique radio-ecological laboratory.

The current placement of wind energy towers in the central and southern Great Plains may have relatively few negative effects on sandhill cranes wintering in the region, according to a U.S. Geological Survey study published today.

Midcontinental sandhill cranes are important to sporting and tourism industries in the Great Plains, an area where wind energy development recently surged. Scientists with the USGS compared crane location data from the winters of 1998-2007 with current wind tower sites in Texas, Oklahoma, Kansas and New Mexico prairies. Findings showed only a seven percent overlap between cranes and towers, and that most towers have been placed in areas not often used by cranes during the winter.

The billions of single-celled marine organisms known as phytoplankton can drift from one region of the world's oceans to almost any other place on the globe in less than a decade, Princeton University researchers have found.

Unfortunately, the same principle can apply to plastic debris, radioactive particles and virtually any other man-made flotsam and jetsam that litter our seas, the researchers found. Pollution can thus become a problem far from where it originated within just a few years.

The globally increasing light pollution has negative effects on organisms and entire ecosystems. The consequences are especially hard on nocturnal insects, since their attraction to artificial light sources generally ends fatal. A new study by Swiss zoologists from the Universities of Basel and Zurich now shows that urban moths have learned to avoid light. The journal Biology Letters has published their results.

Some insects are attracted by light while others shy away from it. Proverbial is the attraction light has on moths. Street lamps and other artificial light sources often become death traps for nocturnal insects such as moths. Either they die through direct burning or through increased exposure to predators. Mortality of urban insects can thus be 40- to 100- fold higher than in rural populations.

WWF welcomes the 2015 Iberian lynx census released today by the government of Andalusia. The survey shows a significant increase in population with the Iberian lynx reaching the highest number since the species was found to be the most endangered cat in the world in 2002.
 
The latest population figure of 404 individuals is up from the 327 recorded in 2014. The survey identified 120 breeding females divided into five areas of the Iberian Peninsula including four in Spain – Doñana, Sierra Morena, Montes de Toledo, Valley Matachel – as well as Portugal’s Vale do Guadiana.
 
 

It’s estimated that there are as few as 3,200 tigers left in the wild — that’s nearly a 97 percent loss in wild tigers over just a century. However, scientists are now saying that the world’s tiger population can double by 2022.
 

El Niño years can have a big impact on the littlest plants in the ocean, and NASA scientists are studying the relationship between the two. In El Niño years, huge masses of warm water – equivalent to about half of the volume of the Mediterranean Sea – slosh east across the Pacific Ocean towards South America. While this warm water changes storm systems in the atmosphere, it also has an impact below the ocean’s surface. These impacts, which researchers can visualize with satellite data, can ripple up the food chain to fisheries and the livelihoods of fishermen.

If there is an animal emblematic of the northern winter, it is the snowshoe hare.

A forest dweller, the snowshoe hare is named for its big feet, which allow it to skitter over deep snow to escape lynx, coyotes and other predators. It changes color with the seasons, assuming a snow-white fur coat for winter camouflage.

But a changing climate and reduced snow cover across the north is squeezing the animal out of its historic range, according to a new study by researchers at the University of Wisconsin-Madison. Writing in the current (March 30, 2016) Proceedings of the Royal Society B, the Wisconsin researchers report that the range of the hare in Wisconsin is creeping north by about five and a half miles per decade, closely tracking the diminishing snow cover the animal requires to be successful.

WWF researchers are celebrating the first live sighting of a Sumatran rhino in Kalimantan, the Indonesia part of Borneo, since it was thought to be extinct there. This is also the first physical contact with the species in the area for over 40 years and is a major milestone for rhino conservation in Indonesia.
 
The female Sumatran rhino, which is estimated to be between four and five years old, was safely captured in a pit trap in Kutai Barat in East Kalimantan on 12 March.
