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.
 
 

Usually the word “jail” brings some harsh imagery to mind: barbed wire fences, orange jumpsuits and tall concrete walls. That’s not the case in the Key West, though. Ask a local about the jail, and the most likely image is Mo, an adorable and charismatic sloth who’s become the unofficial mascot of the Stock Island Detention Center, which doubles as a sanctuary for unwanted animals.

“All the animals here are either abandoned, abused, confiscated or donated,” Jeanne Selander, the caretaker for the facility, explains to Care2. “The animals are here because they need a forever home and we give them one.”

The number of African rhinos poached in 2015 is higher than previously thought with new figures from the International Union for Conservation of Nature (IUCN) showing that a record 1,338 were killed across the continent last year – 33 higher than earlier estimates.
 
This is the highest level since the current poaching crisis began in 2008 and takes the number of African rhinos killed since then to at least 5,940.

Ice melt in the Arctic Ocean is opening up previously untouched areas to industrial fishing fleets using ecologically risky bottom trawling methods, writes Joe Sandler Clarke. Ecosystems supporting walruses, polar bears, puffins and other sea birds could be stripped bare.

Bottom trawling is widely considered to be the among most destructive fishing techniques, with vast nets catching fish as they are dragged along the sea bed.

Using official data and ship tracking systems, researchers found that large numbers of fishing vessels owned by major companies have taken advantage of melting sea ice to fish in previously impossible to reach parts of the Norwegian and Russian Arctic.

For a few weeks in early fall, Georges Bank — a vast North Atlantic fishery off the coast of Cape Cod — teems with billions of herring that take over the region to spawn. The seasonal arrival of the herring also attracts predators to the shallow banks, including many species of whales.

Now researchers from MIT, Northeastern University, the Institute of Marine Research in Norway, and the National Oceanic and Atmospheric Administration, have found that as multiple species of whales feast on herring, they tend to stick with their own kind, establishing species-specific feeding centers along the 150-mile length of Georges Bank. The team’s results are published today in the journal Nature.
