(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.
Scientists discover over 19,000 new species in 2009
(01/19/2012) In 2009 researchers described and named 19,232 species new to science, pushing the number of known species on Earth to just under two million (1,941,939 species), according to the State of Observed Species (SOS). Discoveries included seven new birds, 41 mammals, 120 reptiles, 148 amphibians, 314 fish, 626 crustaceans, and 9,738 insects.
New book series hopes to inspire research in world's 'hottest biodiversity hotspot'
(01/17/2012) Entomologist Dmitry Telnov hopes his new pet project will inspire and disseminate research about one of the world's last unexplored biogeographical regions: Wallacea and New Guinea. Incredibly rich in biodiversity and still full of unknown species, the region, also known as the Indo-Australian transition, spans many of the tropical islands of the Pacific, including Indonesia's Sulawesi, Komodo and Flores, as well as East Timor—the historically famous "spice islands" of the Moluccan Archipelago—the Solomon Islands, and, of course, New Guinea. Telnov has begun a new book series, entitled Biodiversity, Biogeography and Nature Conservation in Wallacea and New Guinea, that aims to compile and highlight new research in the region, focusing both on biology and conservation. The first volume, currently available, also includes the description of 150 new species.
Beyoncé honored with new horse fly named after her
(01/16/2012) Musical artists, and dancer extraordinare, Beyoncé has been awarded a new honor this week: entomologists in Australia have named a new horse fly after the American singer. The new horse fly, dubbed Scaptia beyonceae, is found in Queensland's Atherton Tablelands.
Photos: scientists find new species at world's deepest undersea vent
(01/10/2012) It sounds like a medieval vision of hell: in pitch darkness, amid blazing heat, rise spewing volcanic vents. But there are no demons and devils down here, instead the deep sea vent, located in the very non-hellish Caribbean sea, is home to a new species of pale shrimp. At 3.1 miles below (5 kilometers) the sea's surface, the Beebe Vent Field south of the Cayman islands, is the deepest yet discovered.
Weird carnivorous flower devours worms underground
(01/09/2012) A worm measuring only a millimeter in length scoots its way through relatively massive grains of white sand. The worm, known as a nematode or roundworm, is seeking lunch in the form of bacteria. Suddenly, however, its journey is interrupted: it is caught on a large green surface. Unable to wiggle free the worm is slowly digested, becoming lunch itself for an innocuous purple flower called Philcoxia minensis.
Will Taiwan save its last pristine coastline?
(01/05/2012) Voters in the January 14 Taiwanese presidential election will decide the fate of the island’s last pristine wilderness known as the Alangyi Trail. Amongst the three candidates, only one (Tsai Ing-wen from the Democratic Progressive Party) may support the conservation of Alangyi Trail and its coastline. One of the top domestic stories of 2011 were the efforts by the Pingtung County government, indigenous tribes, and NGOs to preserve the Alangyi Trail, according to the Taiwan Environmental Information Center. Alangyi is now a major issue reflecting steadily growing environmental concern amongst the Taiwanese, but its fate is sadly uncertain.
'Lost world' dominated by Yeti crabs discovered in the Antarctic deep
(01/03/2012) Scientists have discovered a deep sea ecosystem dominated by hairy pale crabs off of Antarctica. The new species of "Yeti crabs" survive alongside many other likely new species, including a seven-armed meat-eating starfish, off of hydrothermal vents, which spew heat and chemicals into the lightless, frigid waters. According to the paper published in PLoS ONE, this is the first discovery of a hydrothermal vent ecosystem in the Southern Ocean though many others have been recorded in warmer waters worldwide.
Estimating the rich diversity of galling insects
(12/12/2011) How does one estimate the number of tiny, cryptic "galling" insects without finding and describing every one (a task that could take centuries of taxonomic work)? According to a new paper in mongabay.com's open access journal Tropical Conservation Science, you count the plants. Galling insects use plant tissue for development creating a "gall," or abnormal growth on the plant. Such little-known insects include gall wasps, gall midges, aphids, and jumping plant lice. The groups are known to be highly diverse, with over 2,000 species described from the US alone; scientists have previously estimated that there may be as many as 132,000 different species.
Photos: two dozen new beetles discovered in Papua New Guinea hotspot
(11/23/2011) Over the past two decades, at least 24 new beetles species have been discovered in a remote mountainous rainforest region of Papua New Guinea by Swedish entomologists Ulf Nylander. Described in the new book Biodiversity, Biogeography and Nature Conservation in Wallacea and New Guinea, the new beetles found in the Aseki Province are all ecologically linked to rotting wood.
Bathtub-sized marine sponge rediscovered after a century of extinction
(11/22/2011) Not found alive for over a century the evocatively named Neptune's cup sponge (Cliona patera) has been rediscovered off the shores of Singapore. Researchers with the environmental consulting DHI Group found the species during a routine dive. Although the specimen they found was small, the goblet-shaped sponge can reach nearly 5 feet (1.5 meters) high and the same in diameter.
800 nearly-extinct giant snails freeze to death in conservation center
(11/14/2011) Eight hundred large carnivorous snails, known as Powelliphanta snails (Powelliphanta augusta), died in a Department of Conservation (DOC) fridge in New Zealand over the weekend. A faulty temperature gauge caused the fridge to cool down to zero degrees Celsius, slowly killing all the molluscs but a lone survivor. The snails in question were taken from Mount Augustus into captivity before their habitat was mined for coal.
Photos: bizarre shell of new snail baffles researchers
(11/10/2011) A new species of snail with a bizarre shell has surprised scientists. Discovered near massive waterfalls in pristine lowland rainforest in New Guinea, the tiny new species' shell is shaped like a cornucopia, spirals flying freely instead of fused together like most shells. Latvian malacologist (one who study molluscs) Kristine Greke, who described the new species, named it Ditropopsis mirabilis, meaning miraculous or extraordinary. To date, scientists are uncertain why the super small snail—2 to 6 millimeters (0.07 to 0.23 inches)—would have evolved such a strange shell.
Beetle bonanza: 84 new species prove richness of Indo-Australian islands
(11/08/2011) Re-examining beetle specimens from 19 museums has led to the discovery of 84 new beetle species in the Macratria genus. The new species span the islands of Indonesia, New Guinea, and the Solomon Islands, tripling the number of known Macratria beetles in the region. "Species of the genus Macratria are cosmopolitan, with the highest species diversity in the tropical rainforests. Only 28 species of this genus were previously known from the territory of the Indo-Australian transition," Dr. Dmitry Telnov with the Entomological Society of Latvia, who discovered the new species, told mongabay.com.
Coral reef biodiversity may be vastly underestimated
(11/03/2011) Researchers with the Smithsonian have catalogued almost as many crab species on tropical coral reef bits measuring just 20.6 square feet (6.3 square meters) as in all of Europe's seas, finds a new paper in PLoS ONE. The team used DNA barcoding to quickly identify a total of 525 crustaceans (including 168 crab species) from dead coral chunks taken from seven sites in the tropics, including the Indian, Pacific and Caribbean oceans.
Picture of the day: cookies and cream moth?
(11/01/2011) This moth species from Panama has not yet been identified by mongabay.com. Moths makes up the bulk of the insect-family Lepidoptera, which also includes butterflies.
Picture of the day: world's scariest species
(10/31/2011) What's the world's scariest species? Runner-up would likely be the mosquito species that transmit malaria. Nearly a million people die from malaria annually, making up some 2.23 percent of deaths worldwide.
Photos: Halloween creepy-crawlies of the natural world
(10/31/2011) Everyone loves the beautiful animals, the playful orangutans, the rolly-polly pandas, the regal tigers, the wise elephants, the awe-inspiring whales, the silly penguins—and it shows. Aside from gracing calendars and starring in movies, these species receive millions in conservation funds and have no shortage of researchers devoted to them. But what about the ugly, crawly, shiver-inducing species? What about those animals that crawl instead of bound,that are slimy instead of furry, that inhabit the deep dark place of the world.
Florida loses two species to extinction
(10/06/2011) The US Fish and Wildlife Service announced yesterday that the believe two species in Florida have vanished into the long dark night: the South Florida rainbow snake (Farancia erytrogramma seminola) and the Florida fairy shrimp (Dexteria floridana). The species were under review for possibly being added to the Endangered Species Act (ESA), but it's likely the review came decades too late.
