Scientists have discovered a new species of fish that glides gently through the water on white, translucent wings 5 miles beneath the ocean surface. The newly discovered species is now the world’s deepest known fish recorded at 8,143 m depth. The fish has a novel body form that has not been seen before. It stunned scientists because in other trenches, there is only one fish species at this depth--a snailfish; this fish is really different from any other deep-sea fish that scientists have ever seen.
"We were just blown away when we saw it," said Paul Yancey, a biology professor at Whitman College, Washington who studies how animals adapt to life in the deep sea. "Someone on the ship said it looks like a cross between a puppy, an angel and an eel." The fish was first spotted in November during an international research cruise to the Mariana Trench -- the deepest place on Earth.
The new fish, which has not yet been named, was discovered by accident. In the video above you can see it swimming around a series of tubes that were part of an instrument collecting mud samples from the sea floor. The camera was supposed to be filming the core collecting, when suddenly this ghostly fish swam into view. It is about 10 inches in length, and almost entirely transparent. The dense white part you can see is actually its skull, visible through its skin, Yancey said. It's lengthy, mostly see-through tail is probably made of gelatin.
"It's moving very slowly so it's not clear how well it can swim," he said. "But there has to be some muscle in there somewhere." The Mariana Trench is located in the Western Pacific, just off the coast of Guam. It starts about 3 miles beneath the ocean surface and stretches to an ultimate depth of 6.8 miles. Humans couldn't survive even at the top rim of the trench. At that depth, the proteins and cells in our membranes would collapse. And at the bottom of the trench, the pressure is so immense it would be like having 100 elephants standing on your head.
One way deep sea animals survive even under the weight of all that water is with a molecule called trimethylamine N-oxide (TMAO) that protects their proteins from being crushed. "It's the molecule that makes marine animals like fish and shrimp smell 'fishy,' " said Yancey, "and in deep sea animals there is a lot more of it."
Paleontologists have documented the evolutionary adaptations necessary for ancient lobe-finned fish to transform pectoral fins used underwater into strong, bony structures, such as those of Tiktaalik roseae.
The recovery of large carnivores in Europe is a great success for nature conservation. At one third of mainland Europe, at least one species of large carnivore is present, according to an article in the scientific magazine Science that researchers from 26 countries have contributed to. It is an excellent example that humans and carnivores can share the same landscape, says main author Guillaume Chapron, from the Swedish University of Agricultural Sciences (SLU)
By the early 20th century, large carnivores had been exterminated from most of Europe, with just relict populations persisting. Now we have increasing or stable populations of brown bears, wolves, Eurasian lynx and wolverines, and they do not live in a remote wilderness but in a human-dominated landscape.
That is a great difference in comparison to the strategies being pursued in other parts of the world where carnivores are mainly protected in large national parks or wilderness areas, separated from people. If Europe had used that model we would hardly have any carnivores at all because there are not enough large areas of wilderness remaining.
Humans didn't invent the idea of combining sex and commerce. Plenty of animals are willing to mate, only if the price is right. Here are 10 animals who will offer sex for reasons other than just preserving the species.
About one tenth of the world’s ants are close relatives; they all belong to just one genus out of 323, called Pheidole. “If you go into any tropical forest and take a stroll, you will step on one of these ants,” says Okinawa Institute of Science and Technology Graduate University’s Professor Evan Economo.Pheidole fill niches in ecosystems ranging from rainforests to deserts. Yet until now, researchers have never had a global perspective of how the many species of Pheidole evolved and spread across the Earth. Economo, researchers in the Biodiversity and Biocomplexity Unit, and colleagues at the University of Michigan compared gene sequences from 300 species ofPheidole from around the world. They used these sequences to construct a tree that shows when and where each species evolved into new species. At the same time, in a parallel effort, they scoured the academic literature, museums around the world, and large databases to aggregate data on where all 1200 or so Pheidole species live on Earth, creating a range map for each species. Their results, published in the Proceedings of the Royal Society Series B, suggest that Pheidole evolved the same way twice, once to take over the New World, and then again to take over the Old World.
“A human being is a part of the whole called by us universe, a part limited in time and space. He experiences himself, his thoughts and feeling as something separated from the rest, a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty.”... ALBERT EINSTEIN
EarthBlog, Glen Barry, August 04, 2014 -▶ NEW SCIENCE SUGGESTS MORE LAND-BASED ECOSYSTEMS LOST THAN BIOSPHERE CAN BEAR. New science finds that two-thirds of Earth’s land-based ecosystems must be protected to sustain the biosphere long-term. Yet about one-half of Earth’s natural ecosystems have already been lost. The scientific review article by Dr. Glen Barry – entitled “Terrestrial ecosystem loss and biosphere collapse” – was published today in the international journal “Management of Environmental Quality”.http://www.ecointernet.org/2014/08/04/biosphere_collapse/
The Mind Unleashed, May 15, 2014 THE EARTH IS A SENTIENT LIVING ORGANISM. Contrary to the common belief that the Earth is simply a dense planet whose only function is a resource for its inhabitants, our planet is in fact a breathing, living organism. When we think of the Earth holistically, as one living entity of its own, instead of the sum of its parts, it takes on a new meaning. Our planet functions as a single organism that maintains conditions necessary for its survival.http://themindunleashed.org/2014/05/earth-sentient-living-organism.html
The Greater the Biodiversity in the Ecosystem, The Greater Resilience of an ecological community and for adaption. Everything is Interconnected and interdependent. Myopic genetic engineering destroys these connections and breaks the link of naturally evolving organisms “A Thousand Invisible Cords: Connecting Genes to Ecosystems” is a 56-minute eco-documentary that can change how we view the world. Community genetics can be used to help save and restore natural ecosystems particularly in view of Climate Change evolutionary impacts. No longer will we see species as isolated members of ecosystems but as genetically connected members of a rich interacting community. In the words of the 19th century naturalist, writer, and environmental activist John Muir: “When we try to pick out anything by itself, we find that it is bound fast by a thousand invisible cords that cannot be broken to everything in the universe.”http://vimeo.com/40615050

▶ IN THE WORLD'S "SIXTH EXTINCTION": ARE HUMANS THE ASTEROID?Elizabeth Kolbert is the author of the new book The Sixth Extinction. It begins with a history of the "big five" extinctions of the past, and goes on to explain how human behavior is creating this sixth one — including our use of fossil fuels and the effects of climate change.
De Waal says animal empathy is underestimated: "There is increasing evidence, mostly in mammals but also in birds, that animals are sensitive to the emotions of others and react to distress in others by attempts to ameliorate their situation or rescue them. There are experiments showing the same, so these videos are to be taken seriously as illustrations of this tendency."
Brazilian biologist Alex Bager has been leading a crusade to raise awareness of a major but neglected threat to biodiversity in his country. Every year over 475 million animals die in Brazil as victims of roadkill, according to an estimate by Centro Brasileiro de Ecologia de Estradas, an initiative funded and coordinated by Bager. This means 15 animals are run down every second on Brazilian roads and highways.
