Monarch butterfly population rises a little, but still perilously low
(01/28/2015) The world's migrating monarch butterfly population has bounced back slightly from its record low last year, but the new numbers are still the second smallest on record. According to WWF-Mexico and the Mexican government, butterflies covered 2.79 acres (1.13 hectares) in nine colonies this year in the Mexican forests where the insects overwinter.
Ocean's 15: meet the species that have vanished forever from our seas
(01/15/2015) In the last 500 years, the oceans have suffered far fewer extinctions than on land—at least that we know of. According to a recent study in Science, 15 animals are known to have vanished forever from the oceans while terrestrial ecosystems have seen 514 extinctions. The researchers, however, warn that the number of marine extinctions could rise rapidly as the oceans are industrialized.
Earthworms under threat
(01/06/2015) 1st November 1837 was a disappointing day at the Geological Society of London. The men (and they were only men) of the Society were expecting great things from the young Charles Darwin, recently returned from his Beagle voyage. Yet on that day only William Buckland saw sufficient value in Darwin’s work to recommend it for publication – but then Buckland himself was an oddity, given his work on fossil feces and his proclivity for eating his way through the Animal Kingdom (moles and bluebottle flies, he reported, are particularly distasteful).
Google Earth used to identify environmentally important termite mounds
(12/17/2014) In woodland and savannah areas, certain termite species play a critical environmental role due to the mounds they build. These mounds can be used as fertilizer to induce new ecosystems, and the termites themselves can be studied as biological indicators of human-caused degradation. Detecting the amount and distribution of these mounds throughout an area can provide importance insight on the overall health of an environment. However, detecting the mounds on the ground can be a costly and time-consuming activity.
To collect or not to collect? Experts debate the need for specimens
(12/10/2014) In 1912, a group of intrepid explorers led by Rollo and Ida Beck, widely acknowledged to be the foremost marine bird collectors of their time, embarked on a most remarkable effort to catalogue South America's oceanic birds. Museums of the day held opportunistically collected specimens from scattered sources, but rarely did these include ocean-bound birds that spent little time near the coast.
Pollinators puzzle to find flowers amidst natural and human fumes
(12/09/2014) While unpleasant car exhaust makes us wrinkle our noses, such human-made fumes may pose serious problems to insects searching for nectar. Researchers recently revealed that background odors make finding flowers difficult for pollinators. The study, published in Science, measured how hawk moths (Manduca sexta) pick out the sacred datura flower scent (Datura wrightii) amidst all the other smells that waft through the environment.
Russia and China blamed for blocking Antarctic marine reserve
(11/03/2014) Another year, another failed attempt to protect a significant chunk of the Ross Sea, which sits off the coast of Antarctica. According to observers, efforts to create the world's biggest marine protected area to date were shot down by Russia and China during a meeting in Hobart, Tasmania of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).
New species named after the struggle for same-sex marriage
(10/13/2014) Scientists have named new species after celebrities, fictional characters, and even the corporations that threaten a species' very existence, but a new snail may be the first to be named after a global human rights movement: the on-going struggle for same-sex marriage. Scientists have named the new Taiwanese land snail, Aegista diversifamilia, meaning diverse human families.
Scientists name new endangered species after the company that will decide its fate
(08/24/2014) Scientists have discovered a new snail species near a cement quarry in Malaysia, which as far as they know lives nowhere else in the world. It lives on a limestone hill called Kanthan given as a concession to an international company Lafarge. The cement producer quarries the hill for raw materials. As a result, the scientists have named the species after the company that will decide if it goes extinct.
Titanium vs. Millipedes: new species discovered in Madagascar threatened by mining
(08/13/2014) A team of scientists from the United States and Germany has recently described seven new species of Malagasy giant pill-millipede. All but one of these species are considered “microendemics,” in that they have only been found in small, isolated forest patches.
The world's best mother: meet the octopus that guards its eggs for over four years
(07/30/2014) The ultimate goal of all species on the planet is procreation, the act of making anew. But few mothers could contend with a deep-sea octopus, known as Graneledone boreopacifica, which researchers have recently observed guarding its eggs for four-and-a-half years (53 months), before likely succumbing to starvation soon after.
It's not just extinction: meet defaunation
(07/24/2014) Get ready to learn a new word: defaunation. Fauna is the total collection of animals—both in terms of species diversity and abundance—in a given area. So, defaunation, much like deforestation, means the loss of animals in all its myriad forms, including extinction, extirpation, or population declines.
Olinguito, tinkerbell, and a dragon: meet the top 10 new species of 2013
(05/22/2014) Out of around 18,000 new species described and named last year, scientists have highlighted ten in an effort to raise awareness about the imperiled biodiversity around us. Each species—from a teddy-bear-like carnivore in the Andes to a microbe that survives clean rooms where spaceships are built—stands out from the crowd for one reason or another.
Scientists discover giant sperm fossilized in bat feces (PHOTOS)
(05/15/2014) In a cave in Australia, researchers from the University of New South Wales discovered giant fossilized sperm. The sperm were produced 17 million years ago by a group of tiny, shelled crustaceans called ostracods, making them the oldest fossilized sperm ever found. The results were published recently in the Proceedings of the Royal Society B.
Underwater horrors: shells of marine life melting off the coast of the U.S.
(05/08/2014) It could be the plot of a horror movie: humans wake up one day to discover that chemical changes in the atmosphere are dissolving away parts of their bodies. But for small marine life known as sea butterflies, or pteropods, this is what's happening off the West Cost of the U.S. Increased carbon in the ocean is melting away shells of sea butterflies.
Wonderful Creatures: life is a gamble (inside a caterpillar) for the trigonalid wasp
(03/27/2014) Among the huge diversity of insects there are some bewilderingly complex life cycles, but few can compete with the trigonalid wasps for the seemingly haphazard way they ensure their genes are passed to the next generation. In most cases, a female parasitoid wasp deposits her eggs on or in the host, but this is far too pedestrian and safe for the trigonalids. These mavericks of the wasp world, which are also parasitoids, like to make things more difficult for themselves.
Scientist discovers a plethora of new praying mantises (pictures)
(03/19/2014) Despite their pacific name, praying mantises are ferocious top predators with powerful, grasping forelimbs; spiked legs; and mechanistic jaws. In fact, imagine a tiger that can rotate its head 180 degrees or a great white that blends into the waves and you'll have a sense of why praying mantises have developed a reputation. Yet, many praying mantis species remain little known to scientists, according to a new paper in ZooKeys that identifies an astounding 19 new species from the tropical forests of Central and South America.
Scientists discover single gene that enables multiple morphs in a butterfly
(03/10/2014) Scientists have discovered the gene enabling multiple female morphs that give the Common Mormon butterfly its very tongue-in-cheek name. doublesex, the gene that controls gender in insects, is also a mimicry supergene that determines diverse wing patterns in this butterfly, according to a recent study published in Nature. The study also shows that the supergene is not a cluster of closely-linked genes as postulated for nearly half a century, but a single gene controlling all the variations exhibited by the butterfly's wings.
Wonderful Creatures: meet the beetle-riding arachnid
(03/06/2014) Without wings, smaller terrestrial animals are really restricted when it comes to moving long distances to find new areas of habitat. However, lots of species get around this problem simply by clinging on to other, more mobile animals. The common, yet overlooked pseudoscorpions are among the most accomplished stowaways, one of which (Cordylochernes scorpiodes) has forged a fascinating relationship with the harlequin beetle, a large, strikingly colored insect.
Wonderful Creatures: the tiny, predatory penis-worm that lies in wait in the sand
(02/28/2014) The seabed is really where it’s at in terms of animal diversity. Of the 35 known animal lineages, representatives of all but two are found here. In contrast, the huge numbers of species that inhabit tropical rainforests represent a mere 12 lineages. One group of animals that illustrates the diversity of the seabed is the Priapulida, which also go by the unfortunate common name of "penis worms." Only 20 species of priapulid are known today, a shadow of their diverse past, which extends back for well over 500 million years. Not commonly seen, the priapulids have attracted little attention from the zoology community as a whole.
Two new wasp species found hidden in museum collections
(02/24/2014) Scientists have identified two new wasp species, years after the specimens were first collected from the wild. The two new species, Abernessia prima and Abernessia capixaba, belong to the rare pompilid genus Abernessia, and are believed to be endemic to Brazil. They made the discovery while examining spider wasp collections from museums in Brazil and Denmark, and published their findings in the journal ZooKeys.
Wonderful Creatures: the bizarre-looking marine worm with an incredibly important ecological role
(02/13/2014) Almost everyone knows what an earthworm is, but these very familiar animals are just one variation on a very rich theme that is at its most fabulously varied in the oceans. The mind-boggling appearances and lifestyles of the marine segmented worms are perfectly exemplified by this week's animal.
Alpine bumblebees capable of flying over Mt. Everest
(02/05/2014) The genus Bombus consists of over 250 species of large, nectar-loving bumblebees. Their bright coloration serves as a warning to predators that they are unwelcome prey and their bodies are covered in a fine coat of hair - known as pile - which gives them their characteristically fuzzy look. Bumblebees display a remarkably capable flight performance despite being encumbered with oversized bodies supported by relatively diminutive wings.
Migrating monarch butterflies hit shockingly low numbers
(01/31/2014) The monarch butterfly population overwintering in Mexico this year has hit its lowest numbers ever, according to WWF-Mexico. Monarch butterflies covered just 0.67 hectares in Mexico's forest, a drop of 44 percent from 2012 already perilously low population. To put this in perspective the average monarch coverage from 1994-2014 was 6.39 or nearly ten times this year's. For years conservationists feared that deforestation in Mexico would spell the end of the monarch migration, but now scientists say that agricultural and policy changes in the U.S. and Canada—including GMO crops and habitat loss—is strangling off one of the world's great migrations.
Wonderful Creatures: meet the animal that has evolved a cushy, worry-free life inside an octopus
(01/30/2014) The range of habitats that animals have come to occupy is nothing short of staggering. Take the dicyemids for example. They are among the simplest animals on the planet, with a tiny, worm-like adult body that consists of between 10 and 40 cells. They have no organs, body cavities or even guts—a structural simplicity which is a consequence of where and how they live. The only place you will find adult dicyemids is inside the bodies of cephalopods, typically octopuses and cuttlefish where large numbers of them cling to the inner wall of the mollusc's kidney.
Amazing discovery in Antarctica: sea anemones found living upside down under ice (photos)
(01/27/2014) Sea anemones are supposed to sit on the bottom of the ocean, using their basal disc (or adhesive foot) to rest on a coral reef orsand. So, imagine the surprise of geologists in Antarctica when they discovered a mass of sea anemones hanging upside from the underside of the Ross Ice Shelf like a village of wispy ghosts. The researchers weren't even there to discover new life, but to learn about south pole currents through the Antarctic Geological Drilling (ANDRILL) Program via a remotely-operated undersea robot.
Spectacular new beetle discovered in French Guiana
(01/21/2014) The discovery of a new, bi-colored beetle species in the lowland rainforest of French Guiana just added a little pizzazz to the ranks of the Pseudomorphini tribe of beetles. With wing cases (elytra) that sport black spots against a rusty red background, the newcomer was dubbed Guyanemorpha spectabilis, or the spectacular Guyane false-form beetle, by entomologist Terry Erwin in the journal ZooKeys.
Wonderful Creatures: A nematode drama played out in a millipede's gut
(01/17/2014) Nematodes are typically small animals that to the naked eye look very much alike; however, these creatures are fantastically diverse —on a par with the arthropods in terms of species diversity. At face value, nematodes lack the charisma of larger animals, so there are very few biologists who have made it their life’s work to understand them. Those who do have been rewarded with a glimpse of the incredible diversity of these animals, an example of which is the complex menagerie of nematodes that dwell in the guts of large, tropical millipedes.
Wonderful Creatures: the lightning-fast Stenus beetles
(01/10/2014) Rove beetles are among the most diverse animals on the planet, with around 56,000 species currently described. Amongst this multitude of species is a dazzling array of adaptations perhaps best illustrated by the genus Stenus. These beetles, with their bulbous eyes and slender bodies are often found near water running swiftly over the wet ground and clambering among the vegetation.
Global warming could upset Antarctic food chain
(01/02/2014) Resting near the bottom of the foodchain, Antarctic krill (Euphausia superba) underpin much of the Southern Ocean's ecosystem. But in a rapidly warming world, these hugely-abundant crustaceans could see their habitat shrink considerably. In a recent paper in PLOS ONE, scientists predict that Antarctic krill could lose 20 percent of their growth habitat, or 1.2 million square kilometers.
Giant clams are easy to recognize, but genetics proves there is more than meets the eye
(12/21/2013) Giant clams are among the more easily spotted invertebrates of the marine realm. However, some are actually quite cryptic and distinct species are often difficult to identify, claims a study recently published in PlosOne. Much attention has been focused on charismatic species in research, but the scientists who authored the study argue that giant clams also deserve the spotlight because of the potential threats and present misunderstandings regarding their taxonimical classifications.
Animal Earth: exploring the hidden biodiversity of our planet
(12/03/2013) Most of the species on Earth we never see. In fact, we have no idea what they look like, much less how spectacular they are. In general, people can identify relatively few of their backyard species, much less those of other continents. This disconnect likely leads to an inability in the general public to relate to biodiversity and, by extension, the loss of it. One of the most remarkable books I have read is a recent release that makes serious strides to repair that disconnect and affirm the human bond with biodiversity. Animal Earth: The Amazing Diversity of Living Creatures written by Ross Piper, a zoologist with the University of Leeds, opens up the door to discovery.
Newly discovered beetles construct private homes out of leaf holes and feces
(11/12/2013) Scientists have discovered two new species of leaf beetles in southern India that display a novel way of using leaf holes and their fecal pellets to build shelters – a nesting behavior previously not known among leaf beetles. Discovered in the forests of the Western Ghats in the states of Karnataka and Kerala, the scientists have named these pin-head sized leaf beetles Orthaltica syzygium and Orthaltica terminalia, after the plants they feed on: Syzygium species (e.g., the Java plum) and Terminalia species (e.g., the flowering murdah).
Beetles in the spotlight: a new species of burying beetle from the Solomon Islands Archipelago
(11/07/2013) If you thought of the little beetle that you saw the other day as just a ‘regular one’ then this might interest you. Scientists from the University of Alaska discovered Nicrophorus efferens, a new species of burying beetle from Solomon Islands. Studying six adult specimens borrowed from the Bernice Pauahi Bishop Museum of Hawaii (BPBM), Dr Sikes and Tonya Mousseau describe the new species in a detailed taxonomic assessment published in the journal Zookeys, and how it differs from two closely related species of the Solomon Islands.
New species of beetle discovered in megacity
(10/30/2013) When imagining the discovery of a new species, most people conjure thoughts of intrepid explorers, battling the odds in remote rainforests. But this needn't be the case, at least according to a new study published in Zookeys. The study reports the discovery of a new species of water beetle in the heart of the 10th largest megacity in the world: Manila, Philippines.
Small invertebrates could be key to uncovering the mysteries of killer amphibian fungus
(10/22/2013) In 2004, the first-ever Global Amphibian Assessment (GAA) reviewed all 5,743 amphibian species known to science and concluded that 32% were threatened with extinction - a number far exceeding corresponding figures for birds and mammals (12 to 23% respectively). In addition to the usual culprits of climate change and habitat destruction, a startling 92.5% of amphibians listed as Critically Endangered were found to be undergoing enigmatic declines linked to an unexpected perpetrator - the chytrid fungus, Batrachochytrium dendrobatidis (Bd).
Featured video: 22-year-old produces documentary on the Peruvian Amazon
(10/15/2013) Spending a year on the Tambopata River in Peru's deep Amazon, allowed 22-year-old Tristan Thompson, to record stunning video of the much the region's little seen, and little known, wildlife. Thompson, a student at the University of the West of England, has turned his footage into a new documentary An Untamed Wilderness that not only gives viewers an inside look at the world's greatest forests, but also records the secretive behavior of many species, including howler monkeys, aracaris, leaf-cutter ants, hoatzin, and giant river otters.
Scientists discover cocoa frog and 60 other new species in remote Suriname (photos)
(10/11/2013) In one of the most untouched and remote rainforests in the world, scientists have discovered some sixty new species, including a chocolate-colored frog and a super-mini dung beetle. The species were uncovered in Southeastern Suriname during a Rapid Assessment Program (RAP); run by Conservation International (CI), RAPS involve sending teams of specialists into little-known ecosystems to record as much biodiversity as they can in a short time. In this case, sixteen researchers from around the world had about three weeks to document the region's biodiversity.
Governments should respond to ocean acidification 'as urgently as they do to national security threats'
(10/03/2013) The oceans are more acidic now than they have been for at least 300m years, due to carbon dioxide emissions from burning fossil fuels, and a mass extinction of key species may already be almost inevitable as a result, leading marine scientists warned on Thursday. An international audit of the health of the oceans has found that overfishing and pollution are also contributing to the crisis, in a deadly combination of destructive forces that are imperiling marine life, on which billions of people depend for their nutrition and livelihood.
New tiny insect named after Peter Pan fairy discovered in Central America
(08/16/2013) A new genus of fairyfly has been discovered in Costa Rica. The new species aptly named Tinkerbella nana after the fairy in J.M. Barrie’s play ‘Peter Pan’ is one of the smallest winged insects in the neotropics. Found in both temperate and tropical climates, the fairyfly is not actually a fly as its name suggests, but instead is more closely related to wasps – being classed within the superfamily Chalcidoidea, or the “chalcid wasps”.
Zoo races to save extreme butterfly from extinction
(08/15/2013) In a large room that used to house aquatic mammals at the Minnesota Zoo, Erik Runquist holds up a vial and says, 'Here are its eggs.' I peer inside and see small specks, pale with a dot of brown at the top; they look like a single grain of cous cous or quinoa. Runquist explains that the brown on the top is the head cap of the larva, a fact that becomes more clear under a microscope when you can see the encased larva squirm. I'm looking at the eggs of a Poweshiek skipperling, a species that is more imperiled than pandas, tigers, or bluewhales. Once superabundant, only several hundred Poweshiek skipperlings may survive on Earth today and the eggs I'm looking at are the only ones in captivity.
Hope rises as new malaria vaccine shows promise
(08/12/2013) Last week U.S. scientists with the biotech company, Sanaria, announced a possible breakthrough on an experimental malaria vaccine: an early trial led to a success rate of 80 percent for the two highest doses. Malaria remains one of the world's worst scourges. In 2010, the World Health Organization reported 219 million documented cases of malaria (millions more likely went undocumented) and estimated that between 660,000 and 1.2 million died of the disease, mostly children in Africa, that year alone. Mortality is not the only impact of the disease, however: experts have long noted circular links between malaria, poverty, and stalled development.
Florida declares two butterfly species extinct as pollinator crisis worsens
(08/01/2013) Conservationist’s faced a crushing blow last month as two butterfly species native to Florida were declared extinct. 'Occasionally, these types of butterflies disappear for long periods of time but are rediscovered in another location,' said Larry Williams, U.S. Fish and Wildlife state supervisor for ecological services. We think it’s apparent now these two species are extinct.'
Habitat loss and pesticides causing decline in Europe's butterflies
(07/31/2013) Europe's grassland butterfly population has plummeted in the past two decades, new research published on Tuesday shows, with a near halving in the numbers of key species since 1990.
Rare animal species and Buddhist monks in danger of losing their home to cement quarry
(07/22/2013) An international cement company Lafarge, winner of a Green Initiative award, is considering quarrying a cave in Malaysia which is the sole home of a critically endangered species. The proposed operations also threaten a Buddhist monastery near the cave where monks are facing eviction. Kanthan cave in Peninsular Malaysia is located in a limestone hill, already extensively quarried for the production of cement by Lafarge. The cave, just as most karst caves in Southeast Asia, harbors a unique ecosystem. One of the rare endemic organisms is the Kanthan Cave trapdoor spider (Liphistius kanthan), which was just designated as Critically Endangered by the IUCN Red List.
Stunning moth species discovered in the mountains of China
(07/17/2013) A new species of moth (Stenoloba solaris) was discovered in the Yunnan province of China, a new addition to the nascent genus of moth, Stenoloba. The discovery was published in the open access journal ZooKeys. The moth is colloquially known as the “sun moth” because of the intricate pattern that covers its upper wings and resembles the rising sun.
Losing our monarchs: iconic monarch butterfly down to lowest numbers in 20 years
(07/15/2013) In the next few months, the beating of fragile fiery orange and black wings will transport the monarch butterfly south. But the number of monarch butterflies (Danaus plexippus) reaching their final destination has steadily declined, dropping to its lowest level in two decades last winter, according to a recent survey.
New long-horned beetle discovered in China
(07/03/2013) Recent expeditions by the Chinese Academy of Science’s Institute of Zoology to the Yunnan Province of China have uncovered the existence of a new species of long-horned beetle. This newly discovered beetle has a beautifully colored blue-green body with short, slender, and distinctively blue legs according to a new article in Zookeys.
Newly discovered pirate ant uses sickle-shaped mandibles to decimate rivals
(06/21/2013) A new species of ant has recently been discovered in the Hortarium of the Los Baños University in the Philippines. Scientists named it the pirate ant (Cardiocondyla pirata) due to the female’s unique pigmentation pattern: a distinctive stripe across the eyes that resembles a pirates’ eye-patch. The pirate ant belongs to a genus Cardiocondyla that are distributed worldwide, but mainly found in the tropics.
Pesticides decimating dragonflies and other aquatic insects
(06/18/2013) While recent research (and media attention) has focused on the alleged negative impacts of pesticides on bees, the problem may be far broader according to a new study in the Proceedings of the US Academy of Sciences (PNAS). Looking at over 50 streams in Germany, France, and Australia, scientists in Europe and Australia found that pesticide contamination was capable of undercutting invertebrate biodiversity by nearly half.
EU labels another pesticide as bad for bees
(06/18/2013) A widely used insect nerve agent has been labelled a "high acute risk" to honeybees by the European Food Safety Authority (EFSA). A similar assessment by the EFSA on three other insecticides preceded the suspension of their use in the European Union.
Ocean acidification pushing young oysters into 'death race'
(06/11/2013) Scientists have long known that ocean acidification is leading to a decline in Pacific oyster (Crassostrea gigas) in the U.S.'s Pacific Northwest region, but a new study in the American Geophysical Union shows exactly how the change is undercutting populations of these economically-important molluscs. Caused by carbon dioxide emissions, ocean acidification changes the very chemistry of marine waters by lowering pH levels; this has a number consequences including decreasing the availability of calcium carbonate, which oysters and other molluscs use to build shells.
Poisonous jellyfish on the rise in the Mediterranean
(06/11/2013) Scientists across the Mediterranean say a surge in the number of jellyfish this year threatens not just the biodiversity of one of the world's most overfished seas but also the health of tens of thousands of summer tourists.
Giant hot pink slug in Australia becomes conservation symbol (photo)
(06/09/2013) Hot pink slugs that emerge after rainy nights have become a conservation symbol for alpine forests on Australia's Mount Kaputar. The slugs, which measure up to 20 centimeters (8 inches), are only found on Mount Kaputar, a volcano that last erupted 17 million years ago. They spend most of their time buried under leaf litter, but emerge by the hundreds when conditions are right to feed on moss, algae, and fungi.
Scientists describe over 100 new beetles from New Guinea
(06/03/2013) In a single paper, a team of researchers have succinctly described 101 new species of weevils from New Guinea, more than doubling the known species in the beetle genus, Trigonopterus. Since describing new species is hugely laborious and time-intensive, the researchers turned to a new method of species description known as 'turbo-taxonomy,' which employs a mix of DNA-sequencing and taxonomic expertise to describe species more rapidly.
Saving Gorongosa: E.O. Wilson on protecting a biodiversity hotspot in Mozambique
(05/30/2013) If you fly over the Great African Rift Valley from its northernmost point in Ethiopia, over the great national parks of Kenya and Tanzania, and follow it south to the very end, you will arrive at Gorongosa National Park in central Mozambique. Plateaus on the eastern and western sides of the park flank the lush valley in the center. Dramatic limestone cliffs, unexplored caves, wetlands, vast grasslands, rivers, lakes, and a patchwork of savanna and forest contribute to the incredible diversity of this park. What makes this place truly unique, however, is Mount Gorongosa—a towering massif that overlooks the valley below.
Two new arachnids discovered in Brazilian caves (photos)
(05/29/2013) Scientists have discovered two new species of short-tailed whipscorpions (in the order Schizomida) in limestone caves in Brazil, according to a new paper published in PLoS ONE. The new species—dubbed Rowlandius ubajara and Rowlandius potiguara—add new knowledge to a group of arachnids that is little known in South America outside of the Amazon.
Scientists discover two mini-spiders in China (photos)
(05/23/2013) Scientists have uncovered two miniature spiders living on mountains in China's southern region, one of which is among the smallest spiders recorded worldwide, according to a new paper in ZooKeys. Both spiders belong to the Mysmenidae family, which is made up of mini-spiders with eight eyes.
Three new species of carnivorous snails discovered in endangered habitat in Thailand (photos)
(05/23/2013) Scientists from Chulalongkorn University, Bangkok and the Natural History Museum, London recently discovered three new species of carnivorous snails in northern Thailand. However, the celebration of these discoveries is tainted by the fact that the new snails are already threatened with extinction due to the destruction of their limestone habitat.
New prehistoric animal named after Johnny Depp due to its 'scissorhands'
(05/19/2013) Half a billion years after an arthropod with long triple claws roamed the shallow Cambrian seas, scientists have named it after Hollywood movie actor, Johnny Depp: Kooteninchela deppi. Depp, known for his versatility as an actor, played Edward Scissorhands—an artificial man with long scissors for hands—in a popular 1990 film.
Eat insects to mitigate deforestation and climate change
(05/14/2013) A new 200-page-report by the UN Food and Agriculture Organization (FAO) urges human society to utilize an often-ignored, protein-rich, and ubiquitous food source: insects. While many in the industrialized west might turn up their noses at the idea of eating insects, already around 2 billion people worldwide eat over 1,900 species of insect, according to the FAO. Expanding insect-eating, the authors argue, may be one way to combat rising food needs, environmental degradation, and climate change.
Common moth can hear higher frequencies than any other animal on Earth
(05/09/2013) A common little moth turns out to have the best ears in the animal kingdom. According to a new study in Biology Letters, the greater wax moth (Galleria mellonella) is capable of hearing frequencies up to 300,000 hertz (300kHz), which is 15 times the frequency humans can hear at their prime, around 20 kHz.
U.S. loses nearly a third of its honey bees this season
(05/09/2013) Nearly a third of managed honeybee colonies in America died out or disappeared over the winter, an annual survey found on Wednesday. The decline—which was far worse than the winter before—threatens the survival of some bee colonies. The heavy losses of pollinators also threatens the country's food supply, researchers said. The US Department of Agriculture has estimated that honeybees contribute some $20bn to the economy every year.
Looking beyond the hundred legs: finding new centipedes in India requires many tools
(04/08/2013) A small, boneless creature, that lives underground, with a "hundred" legs, and a rather powerful sting; some of these creatures are drab, but some are so beautiful and brightly colored that they can startle. Centipedes. There is more to a centipede than its many legs, and its habit of darting out of dark places. One of the first lifeforms to turn up on land, some centipede fossils date back to about 450 million years ago. They have been evolving steadily since, with some estimates showing about 8,000 species today. Not even half of these species have been taxonomically described.
New giant tarantula that's taken media by storm likely Critically Endangered (photos)
(04/04/2013) Described by a number of media outlets as "the size of your face" a new tree-dwelling tarantula discovered in Sri Lanka has awed arachnophiliacs and terrified arachnophobes alike. But the new species, named Raja's tiger spider (Poecilotheria rajaei), is likely Critically Endangered according to the scientist that discovered it in northern Sri Lanka.
Scientists discover new wasp species in a field box from the 1930s (photos)
(04/03/2013) Searching through materials at the Natural History Museum in Paris, Simon van Noort recently came across a long-neglected field box of wasp specimens. Collected 80 years earlier by André Seyrig in Madagascar, the box contained several specimens of wasp in the Paramblynotus genus. The big surprise: wasps in this genus had never before been seen in Madagascar.
Domesticated bees do not replace declining wild insects as agricultural pollinators
(04/03/2013) Sprinkled with pollen, buzzing bees fly from one blossom to another, collecting sweet nectar from brilliantly colored flowers. Bees tend to symbolize the pollination process, but there are many wild insects that carry out the same function. Unfortunately, wild insect populations are in decline, and, according to a recent study, adding more honey bees may not be a viable solution.
Scientists discover new genus of crustacean
(03/27/2013) In recent journeys to Madagascar, New Caledonia, Vanuatu, the Philippines, and French Polynesia, scientists from the Centre for Advanced Studies of Blanes and the University of Barcelona have discovered not only five new crustaceous species, but also the existence of a new genus in the family.
Common pesticides disrupt brain functioning in bees
(03/27/2013) Exposure to commonly used pesticides directly disrupts brain functioning in bees, according to new research in Nature. While the study is the first to record that popular pesticides directly injure bee brain physiology, it adds to a slew of recent studies showing that pesticides, especially neonicotinoids, are capable of devastating bee hives and may be, at least, partly responsible for on-going Colony Collapse Disorder (CCD).
Ant communities more segregated in palm oil plantations than rainforest
(03/21/2013) Ants are an important ecological group in both degraded and natural habitats. They interact with many other species and mediate a range of ecological processes. These interactions are often interpreted in the context of ant mosaics, where dominant species form strict territories, keeping other ants out. This segregation between ant species is well-documented in monoculture plantations. Now new research published in Ecography has shown that these changes are driven by the replacement of rainforests with monocultures and not the arrival of non-native species.
Giant squid caught on video
(01/08/2013) Last summer, after 55 dives, three scientists in a submarine off the coast of Japan encountered an animal people have mythologized and feared for thousands of years: the giant squid. According to the researchers with Japan's National Science Museum they managed to capture the first footage ever (see below) of a giant squid in its natural habitat, although photos were also released in 2005 of a giant squid feeding.
Animals dissolving due to carbon emissions
(12/03/2012) Marine snails, also known as sea butterflies, are dissolving in the Southern Seas due to anthropogenic carbon emissions, according to a new study in Nature GeoScience. Scientists have discovered that the snail's shells are being corroded away as pH levels in the ocean drop due to carbon emissions, a phenomenon known as ocean acidification. The snails in question, Limacina helicina antarctica, play a vital role in the food chain, as prey for plankton, fish, birds, and even whales.
New study adds to evidence that common pesticides decimating bee colonies
(10/24/2012) The evidence that common pesticides may be partly to blame for a decline in bees keeps piling up. Several recent studies have shown that pesticides known as "neonicotinoid" may cause various long-term impacts on bee colonies, including fewer queens, foraging bees losing their way, and in some cases total hive collapse. The studies have been so convincing that recently France banned the use of neonicotinoid pesticides. Now a new study finds further evidence of harm caused by pesticides, including that bees who are exposed to more than one chemical, i.e. neonicotinoid and pyrethroid, were the most vulnerable.
Brainless slime mold uses slimy memory to navigate
(10/08/2012) How do you navigate space efficiently without a brain? Slime, according to a surprising new study in the Proceedings of the National Academy of Sciences (PNAS) of a brainless slime mold named Physarum polycephalum. Scientists at the University of Sydney have discovered that the mold secretes slime as an 'external spatial memory' to make sure it doesn't end up going around in circles.
Arachnopocalypse: with birds away, the spiders play in Guam
(09/17/2012) The island of Guam is drowning in spiders. New research in the open-access journal PLOS ONE has found that in the wet season, Guam's arachnid population booms to around 40 times higher than adjacent islands. Scientists say this is because Guam, a U.S. territory in the Pacific, has lost its insect-eating forest birds. Guam's forests were once rich in birdlife until the invasion of non-native brown tree snake (Boiga irregularis) in the 1940s decimated biodiverse bird communities. Now, the island is not only overrun with snakes, but spiders too.
Sacrificial squid has unique way of deterring predators
(09/04/2012) Octopoteuthis deletron—this deep-dwelling, unassuming little squid may appear plain and boring, but when threatened, it has a peculiar way of defending itself. This foot-long invertebrate behaves a bit differently than most of its close cousins: it drops its arms.
Biodiversity faltering: 20% of invertebrates threatened with extinction
(08/31/2012) Twenty percent of invertebrates are at risk of extinction, according to a new report that looks at the 12,621 invertebrates assessed by the IUCN Red List to date. Although invertebrates never garner the same conservation attention as big, charismatic animals such as tigers and elephants, they play an undeniable role in maintaining healthy ecosystems. In addition, since invertebrates make-up 80 percent of the world's species, the report raises new concerns about global biodiversity decline.
Unidentified poodle moth takes Internet by storm
(08/29/2012) A white moth from Venezuela that bears a striking resemblance to a poodle has become an Internet sensation, after cryptozoologist Karl Shuker posted about the bizarre-looking species on his blog. Photographed in 2009 in Venezulea's Canaima National Park in the Gran Sabana region by zoologist Arthur Anker from Kyrgyzstan, the white, cuddly-looking moth with massive black eyes has yet to be identified and could be a species still unknown to science.
'Monster larva' turns into a shrimp
(08/28/2012) With blue devil-shaped horns and red armor, the monster larva, or Cerataspis monstrosa, kept scientists guessing for nearly 200 years; infrequently found in the bellies of marine predators, researchers could not imagine what this larva became as an adult. Now they do: the monster larva becomes a deep sea shrimp, known as Plesiopenaeus armatus, which bares little monstrous resemblance to its larval stage, according to DNA studies published in Ecology and Evolution.
One extinction leads to another...and another
(08/28/2012) A new study in Biology Letters demonstrates that altering the relationship between a predator and its prey can cause wide-ranging ripple effects through an ecosystem, including unexpected extinctions. Species help each other, directly or indirectly, which scientists refer to as mutualism or commensalism. For example, a species’ success may rely not only upon the survival of its food source, but may also indirectly rely upon the survival of more distantly related species.
Illegal lobster fishermen slammed with over $50 million penalty
(08/21/2012) Three men who illegally harvested lobster from South African waters and smuggled them to the U.S. for 14 years have been ordered to pay $54.9 million in restitution to the South African government by a District Court in Manhattan. According to the Pew Environment Group this is the largest restitution order under the U.S. Lacey Act, which deals with the illegal wildlife trade. The judgement, however, still requires the approval of a district judge.
Velociraptor spider discovered in Oregon cave (pictures)
(08/17/2012) Scouring the caves of Southwest Oregon, scientists have made the incredible discovery of a fearsome apex predator with massive, sickle claws. No, it's not the Velociraptor from Jurassic Park: it's a large spider that is so unique scientists were forced to create a new taxonomic family for it. This is the first new spider family to be discovered in North America in over 130 years. 'This is something completely new,' lead author of a paper on the species, Charles Griswold with the California Academy of Sciences, told SFGate. 'It's a historic event.'
New Malaysian snail named after late conservation mentor
(07/30/2012) Researchers have discovered a new snail, which is so unusual that it has been granted its own genus: Kenyirus. To date, the mysterious forest snail, found in Malaysia's Kenyir Forest, is only known from its unique shell.
96 percent of the world's species remain unevaluated by the Red List
(06/28/2012) Nearly 250 species have been added to the threatened categories—i.e. Vulnerable, Endangered, and Critically Endangered—in this year's update of the International Union for Conservation of Nature's (IUCN) Red List. The 247 additions—including sixty bird species—pushes the number of threatened species globally perilously close to 20,000. However to date the Red List has only assessed 4 percent of the world's known species; for the other 96 percent, scientists simply don't know how they are faring.
New tiny crustacean discovered in deep sea off Europe (photo)
(06/20/2012) Scientists have pulled up a tiny new species of 'squat lobster' from a deep sea mountain at 1,410 meters below sea level off the coast of Spain. Dubbed Uroptychus cartesi, this is only the fourth species in this genus from the eastern Atlantic Ocean, although there are over hundred unique species in the Pacific and Indian ocean. The new species measures just 5-7 centimeters.
Forgotten Species: the wonder-inducing giant clam
(06/11/2012) The first time I ever saw a giant clam was at a ride in Walt Disney World's Magic Kingdom. My family and I piled into the Nautilus submersible at the 20,000 Leagues Under the Sea: Submarine Voyage and descended into the playtime depths. While we saw sea turtles, sharks, lobsters, mermaids, and even a sea monster, the creature that lingered in my mind most was the giant clam, raising and closing its pearly shell in the weedy abyss. Of course, none of these aquatic wonders were real—they were animatronics—but to a child with a vivid imagination they stirred within me the deep mystery of the boundless ocean, and none more so than that monstrous clam with its gaping maw.
After damning research, France proposes banning pesticide linked to bee collapse
(06/04/2012) Following research linking neonicotinoid pesticides to the decline in bee populations, France has announced it plans to ban Cruiser OSR, an insecticide produced by Sygenta. Recent studies, including one in France, have shown that neonicotinoid pesticides likely hurt bees' ability to navigate, potentially devastating hives. France has said it will give Sygenta two weeks to prove the pesticide is not linked to the bee decline, known as Colony Collapse Disorder (CCD).
Blue tarantula, walking cactus, and a worm from Hell: the top 10 new species of 2011
(05/23/2012) A sneezing monkey, a blue tarantula, and an extinct walking cactus are just three of the remarkable new species listed in the annual Top Ten New Species put together by the International Institute for Species Exploration at Arizona State University. This year's list includes a wide-variety of life forms from fungi to flower and invertebrate to primate.
Eye-popping purple crabs discovered in the Philippines
(04/23/2012) Scientists have discovered four new species of brilliantly-colored freshwater crabs on the Philippine island of Palawan. Described in the Raffles Bulletin of Zoology, the new species expands the genus, Insulamon, from one known crab species to five. Although its ecosystems are threatened by widespread mining and deforestation, the Philippines is a mega-diverse country, meaning that it belongs to a select group of 17 countries that contain the bulk of the world's species.
Researchers recreate bee collapse with pesticide-laced corn syrup
(04/05/2012) Scientists with the Harvard School of Public Health (HSPH) have re-created the mysterious Colony Collapse Disorder in several honeybee hives simply by giving them small doses of a popular pesticide, imidacloprid. Bee populations have been dying mysteriously throughout North America and Europe since 2006, but the cause behind the decline, known as Colony Collapse Disorder, has eluded scientists. However, coming on the heels of two studies published last week in Science that linked bee declines to neonicotinoid pesticides, of which imidacloprid is one, the new study adds more evidence that the major player behind Colony Collapse Disorder is not disease, or mites, but pesticides that began to be widely used in the 1990s.
Smoking gun for bee collapse? popular pesticides
(03/29/2012) Commonly used pesticides may be a primary driver of the collapsing bee populations, finds two new studies in Science. The studies, one focused on honeybees and the other on bumblebees, found that even small doses of these pesticides, which target insect's central nervous system, impact bee behavior and, ultimately, their survival. The studies may have far-reaching repercussions for the regulation of agricultural chemicals, known as neonicotinoid insecticides, that have been in use since the 1990s.
Beyond Bigfoot: the science of cryptozoology
(03/26/2012) Anyone who doubts cryptozoology, which in Greek means the "study of hidden animals," should remember the many lessons of the past 110 years: the mountain gorilla (discovered in 1902), the colossal squid (discovered in 1925, but a full specimen not caught until 1981), and the saola (discovered in 1992) to name a few. Every year, almost 20,000 new species are described by the world's scientists, and a new book by Dr. Karl Shuker, The Encycloapedia of New and Rediscovered Animals, highlights some of the most incredible and notable new animals uncovered during the past century.
Scientists discover world's deepest terrestrial animal
(02/22/2012) It's not the prehistoric monsters from the Jules Verne's Journey to the Center of the Earth or the human-bat hybrids of The Decsent, but it's an astonishing discovery nonetheless: intrepid scientists have discovered the world's deepest surviving terrestrial animal to date, a small wingless insect known as a springtail. Explorers discovered the new species, Plutomurus ortobalaganensis at a shocking 1.23 miles (1.98 kilometers) below the surface. The species was discovered by the Ibero-Russian CaveX Team Expedition in Krubera-Voronja Cave, the world's only known cave to go deeper than 2 kilometers.
Innovative conservation: wild silk, endangered species, and poverty in Madagascar
(02/20/2012) For anyone who works in conservation in Madagascar, confronting the complex difficulties of widespread poverty is a part of the job. But with the wealth of Madagascar's wildlife rapidly diminishing— such as lemurs, miniature chameleons, and hedgehog-looking tenrecs found no-where else in the world—the island-nation has become a testing ground for innovative conservation programs that focus on tackling entrenched poverty to save dwindling species and degraded places. The local NGO, the Madagascar Organization of Silk Workers or SEPALI, along with its U.S. partner Conservation through Poverty Alleviation (CPALI), is one such innovative program. In order to alleviate local pressure on the newly-established Makira Protected Area, SEPALI is aiding local farmers in artisanal silk production from endemic moths. The program uses Madagascar's famed wildlife to help create more economically stable communities.
Jurassic insect sings again
(02/06/2012) Innovative research has made a long-extinct katydid—which inhabited the world of dinosaurs like stegosaurus, allosaurus, and diplodocus—sing again. The discovery of an incredibly well-preserved fossil of a new species of katydid, dubbed Archaboilus musicus, gave biomechanical experts the opportunity to recreate a song not heard in 165 million years according to new research published in the Proceedings of the National Academy of Sciences (PNAS).
Jellyfish explosion may be natural cycle
(02/06/2012) Evidence that jellyfish are taking over the oceans is currently lacking, according to a new study published in Bioscience. Complied by a number of marine experts, the study found that while jellyfish have been on the rise in some regions it is likely due to a natural cycle of jellyfish populations and not a global boom. Researchers, including a number of marine biologists, have warned for years that jellyfish numbers may be exploding due to human activities, such as overfishing, warmer oceans due to global climate change, and the rise of oxygen-depleted, so-called "dead zones."
Photo of the day: super-abundance of life found in Amazon park
(02/02/2012) Surveying a little-explored park in the Peruvian Amazon has paid off in dividends: researchers with the Wildlife Conservation Society (WCS) have cataloged 365 species that had not yet been recorded in Bahuaja Sonene National Park. The never-before recorded species included two bats, thirty birds, and over two hundred butterflies and moths.
Photos: 46 new species found in little-explored Amazonian nation
(01/25/2012) South America's tiniest independent nation still hides a number of big surprises: a three week survey to the sourthern rainforests of Suriname found 46 potentially new species and recorded nearly 1,300 species in all. Undertaken by Conservation International's (CI) Rapid Assessment Program (RAP) the survey found new species of freshwater fish, insects, and a new frog dubbed the "cowboy frog" for the spur on its heel. While Suriname may be small, much of its forest, in the Guyana Shield region of the Amazon, remains intact and pristine. The Food and Agriculture Organization (FAO) estimates that 91 percent of Suriname is covered in primary forests, however this data has not been updated in over two decades.
Acid oceans: in some regions acidification a 'hundred times greater' than natural variation
(01/24/2012) Emissions of carbon over the last two centuries have raised the acidity of the oceans to the highest levels in 21,000 years and likely beyond, according to a new study in Nature Climate Change. The change threatens a number of marine species, including coral reefs and molluscs.
Economic slowdown leads to the pulping of Latvia's forests
(01/23/2012) The economic crisis has pushed many nations to scramble for revenue and jobs in tight times, and the small Eastern European nation of Latvia is no different. Facing tough circumstances, the country turned to its most important and abundant natural resource: forests. The Latvian government accepted a new plan for the nation's forests, which has resulted in logging at rates many scientists say are clearly unsustainable. In addition, researchers contend that the on-the-ground practices of state-owned timber giant, Latvijas Valsts meži (LVM), are hurting wildlife and destroying rare ecosystems.
