Cunning carnivorous plants catch more prey by letting some go
(02/25/2015) Pitcher plants (Nepenthes species) have long captivated our fascination. Typically growing in acidic and nutrient-poor soils, they have developed the ability to eat insects and other small prey to supplement their diets. Nepenthes grow modified leaf structures which form a saucer cup with a slippery rim lined with visual or edible bait. When an insect approaches to investigate the reward, they slip off the rim and into the cup which is usually filled with a viscoelastic fluid. Unable to escape, the prey is slowly digested and absorbed by the plant.
Pollinator collapse could lead to a rise in malnutrition
(02/09/2015) Saving the world's pollinators may be a public health issue, according to recent research. Scientists have long believed that pollinators are important for human nutrition, but this is first time they have tested the hypothesis. What they found is disturbing: pollinator collapse could increase nutrient deficiency across local populations by a up to 56 percent in four developing counties.
How termites hold back the desert
(02/05/2015) Some termite species erect massive mounds that look like great temples springing up from the world's savannas and drylands. But aside from their aesthetic appeal—and incredible engineering—new research in Science finds that these structures do something remarkable for the ecosystem: they hold back the desert.
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.
Two vanishing prairie butterflies added to the Endangered Species Act
(01/05/2015) This fall, the U.S. Fish and Wildlife Service added two little-known prairie butterflies to the Endangered Species Act. One of the species, the Poweshiek skipperling, may be down to only a few hundred individuals. The Dakota skipperling is faring a little better, but both have lost the majority of their habitat in the pass few hundred years and continue to decline.
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.
Gone for good: world's largest earwig declared extinct
(11/19/2014) The world has lost a giant: this week the IUCN Red List officially declared St. Helena giant earwig extinct. While its length of 80 millimeters (3.1 inches) may not seem like much, it's massive for an earwig and impressive for an insect. Only found on the island of St. Helena in the remote southern Atlantic, experts believe the St. Helena giant earwig was pushed to extinction by habitat destruction.
Pesticides harm bumblebees' ability to forage
(10/31/2014) Bumblebees exposed to pesticides suffered adverse effects to their foraging behavior, according to a new study co-authored by Nigel Raine and Richard Gill in the journal Functional Ecology. Bumblebees are essential insect pollinators that are vital to healthy crop yields and biodiversity, but their populations have been in decline.
Termites suffer in logged forests and palm oil plantations
(09/25/2014) Ants appear more resilient to forest degradation than termites. Scientists have long studied how birds, mammals, and amphibians respond to forest degradation, but what about the most abundant animals in the forest? Insects. A new study in Biodiversity and Conservation looks at how ants and termites reacted to forest changes in Malaysian Borneo.
'Canary in the cornfield': monarch butterfly may get threatened species status
(09/08/2014) Monarch butterflies were once a common sight throughout the North American heartland. But declines in milkweed – their caterpillars’ only source of food – have led to a 90 percent decline in monarch numbers. Now, the U.S. Fish and Wildlife Service is reviewing a petition that would grant the iconic species protection through the Endangered Species Act.
Scientists honor missing activist by naming a spider after him
(08/25/2014) Swiss researchers have honored the memory of a missing indigenous peoples activist by naming an undescribed species of spider after him, reports the Bruno Manser Fund, the group he founded.
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.
'Stop using the bloody things': pesticides linked to bee collapse now blamed for bird declines
(07/15/2014) In recent years the evidence has piled up that neonicotinoids—a hugely popular group of pesticide—may be at least partly responsible for ongoing bee and pollinator collapse. But new research in the journal Nature find that these pesticides could also be taking a heavy toll on other species, in this case common birds.
They think, therefore they spread: plants can make complex conditional decisions
(07/07/2014) Strong memory, being able to predict the future, and acting based on one’s surroundings are traits typically associated only with the most advanced types of animals. However, a team of German and Dutch scientists from the Helmholtz Center for Environmental Research (UFZ) and the University of Göttingen found ecological evidence that plants also have these abilities.
Horror movie bugs: new wasp species builds nest with the bodies of dead ants
(07/02/2014) If ants made horror movies this is probably what it would look like: mounds of murdered ants sealed up in a cell. The villain of the piece—at least from the perspective of the ants—is a new species of spider wasp, which scientists have aptly dubbed the bone-house wasp (Deuteragenia ossarium) in a paper released today in PLOS ONE.
Fly and wasp biodiversity in Peru linked to strange defense strategy
(06/18/2014) Entomologists working in Peru have revealed new and unprecedented layers of diversity amongst wasps and flies. The paper, published in the journal Science, also describes a unique phenomenon in which flies actually fight back and kill predatory parasitic wasps.
More is better: high bee biodiversity boosts crop yields
(06/12/2014) Scientists have discovered that blueberry plants visited by more diverse bee species increased their seed number, berry size and fruit set, and quickened their ripening time. They hope their findings encourage farmers to help support local wild bee communities.
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.
The Harry Potter wasp: public votes to name new species after soul-sucking ghouls
(05/05/2014) Whether a die-hard Harry Potter fan or not, you probably know what dementors are. They were the guards of Azkaban —dark hooded evil beings that sucked the soul out of their victims, leaving them alive but 'empty-shelled.' These fictional creatures now share their name with a new species of cockroach wasp, insects that turn cockroaches into zombies.
The enemy of your enemy is your ant bodyguard: spider uses one predator for protection against another
(04/09/2014) The notion of spiders using ants as bodyguards seems a bit contradictory, but that is exactly what occurs on the tropical forest floors of the Philippines. The jumping spider strategically nests within the vicinity of the aggressive Asian weaver ant as a defense tactic against its main predator, the spitting spider.
U.S. citizens willing to spend billions to protect monarch butterflies
(04/03/2014) New research shows Americans are willing to pay for the protection of the ailing monarch butterfly, which is experiencing a steep decline in numbers. The study, published in Conservation Letters, found nearly three-quarters of those surveyed placed importance on conservation efforts for the iconic species.
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.
Sloths, moths and algae: a surprising partnership sheds light on a mystery
(03/22/2014) While it spends the majority of its time in the safety of tree canopies, the three-toed sloth regularly places itself in mortal danger by descending to the forest floor to defecate. For years, scientists have been trying to figure out what is driving this peculiar and risky behavior. Now, Jonathan Pauli from the University of Wisconsin-Madison believes his team of researchers has found an important clue to this mystery involving an unusual and beneficial relationship among sloths, moths and algae.
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.
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.
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.
How “insect soup” might change the face of conservation
(01/23/2014) Much of what we know about patterns of biodiversity has come from extensive fieldwork, with expert researchers sampling and identifying species in a process that takes thousands of man-hours. But new technologies may revolutionize this process, allowing us to monitor changes in biodiversity at speeds and scales unimaginable just a decade ago.
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: 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.
Bee-harming pesticides may impact human nervous system
(12/23/2013) Neonicotinoid pesticides, which have been increasingly blamed for the collapse of bee populations, may also impact human's developing nervous system, according to a review of research by the European Food Safety Authority (EFSA). The EFSA says that current safety guidelines for two pesticides—acetamiprid and imidacloprid—may be too lax to protect humans, especially the developing brains of unborn children
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.
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.
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.
Losing just one pollinator species leads to big plant declines
(07/22/2013) A shocking new study finds that losing just one pollinator species could lead to major declines in plant productivity, a finding that has broad implications for biodiversity conservation. Looking at ten bumblebee species in Colorado alpine meadows, two scientists found that removing a single bee species cut flower seed production by one-third. Pollinators worldwide are in major trouble as they are hit by habitat loss, pesticides, disease and other impacts. In fact, the EU has recently banned several pesticides that have been linked to the global bee decline.
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.
Warming world hits fig wasps and figs
(06/19/2013) Recent experiments concerning hugely-important fig plants (Ficus) and their relationship with small, short-lived fig wasps suggest dire potential consequences due to human induced climate change, finds a study published in the journal Biology Letters. The researchers collected four species of adult female fig wasps from the lowland tropical forests of Singapore to test their tolerance to gradually increased temperatures.
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.
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.
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.
Widely used insecticide contaminating water supplies, triggering wildlife die-off in Europe
(05/03/2013) The world's most widely used insecticide is devastating dragonflies, snails and other water-based species, a groundbreaking Dutch study has revealed.
Europe bans pesticides linked to bee collapse
(04/29/2013) The EU has banned three neonicotinoid pesticides (imidacloprid, clothianidin and thiamethoxam) linked to the decline of bees for two years. The ban will apply to all flowering crops, such as corn, rape seed, and sunflowers. The move follows a flood of recent studies, some high-profile, that have linked neonicotinoid pesticides, which employ nicotine-like chemicals, to the widespread decline of bees seen both in Europe and North America.
Madagascar swamped by locust invasion
(04/17/2013) More than 60 percent of Madagascar is suffering from a massive locust infestation that is threatening crops and livestock, potentially increasing risks to native wildlife and forests from hungry farmers, warns the U.N. Food and Agriculture Organization (FAO).
Future generations to pay for our mistakes: biodiversity loss doesn't appear for decades
(04/15/2013) The biodiversity of Europe today is largely linked to environmental conditions decades ago, according to a new large-scale study in the Proceedings of the National Academy of Sciences (PNAS). Looking at various social and economic conditions from the last hundred years, scientists found that today's European species were closely aligned to environmental impacts on the continent from 1900 and 1950 instead of more recent times. The findings imply that scientists may be underestimating the total decline in global biodiversity, while future generations will inherit a natural world of our making.
New insect discovered in Brazil, only third known in its bizarre family (photos)
(04/15/2013) A new species of forcepfly named Austromerope brasiliensis, was recently discovered in Brazil and described in the open access journal Zoo Keys. This is the first discovery of forcepfly in the Neotropics and only the third known worldwide. The forcepfly, often called the earwigfly because the male genital forceps closely resemble the cerci of the common earwig, remains a scientific enigma due to the lack of information on the family.
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.
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.
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.
Warlords, sorcery, and wildlife: an environmental artist ventures into the Congo
(02/25/2013) Last year, Roger Peet, an American artist, traveled to the Democratic Republic of Congo (DRC) to visit one of the world's most remote and wild forests. Peet spent three months in a region that is largely unknown to the outside world, but where a group of conservationists, headed by Terese and John Hart, are working diligently to create a new national park, known as Lomami. Here, the printmaker met a local warlord, discovered a downed plane, and designed a tomb for a wildlife ranger killed by disease, in addition to seeing some of the region's astounding wildlife. Notably, the burgeoning Lomami National Park is home to the world's newest monkey species, only announced by scientists last September.
EU pushes ban on pesticides linked to bee downfall
(02/05/2013) Following a flood of damning research on the longterm impact of neonicotinoid pesticides on bee colonies, the EU is proposing a two year ban on the popular pesticides for crops that attract bees, such as corn, sunflower, oil seed rape, cotton. The proposal comes shortly after European Food Safety Authority (EFSA) released a report that found neonicotinoid pesticides posed a "number of risks" to bees.
Bloodsucking flies help scientists identify rare, hard-to-find mammals
(01/16/2013) Last year scientists released a study that is likely to revolutionize how conservationists track elusive species. Researchers extracted the recently sucked blood of terrestrial leeches in Vietnam's remote Annamite Mountains and looked at the DNA of what they'd been feeding on: remarkably researchers were able to identify a number of endangered and rarely-seen mammals. In fact two of the species gleaned from these blood-meals had been discovered by scientists as late as the 1990s. In the past, trying to find rare and shy jungle animals required many man hours and a lot of funding. While the increasing use of remote camera traps has allowed scientists to expand their search, DNA sampling from leeches could be the next big step in simplifying (and cheapening) the quest for tracking the world's mammals.
Scary caterpillar fungus could lead to new cancer drug
(01/14/2013) Cordyceps sinensis, commonly known as caterpillar fungus, may be a groundbreaking new treatment for a number of life-threatening conditions including asthma, kidney failure and cancer according to a paper recently published by The RNA Society. If you’re a caterpillar of the Tibetan Plateau, the fungus Cordyceps is your worst nightmare. It hits you when you’re most vulnerable, during hibernation. You can try to stay awake, but on the Tibetan plateau, which reaches −40 degrees Celsius during the winter, you’ll have to hibernate sooner or later, and the fungus will be waiting for you.
Mercury hurts birds and people: what we can learn from studying our feathered friends
(01/07/2013) Birds aren't that different from people. We learn from our parents, just like zebra finches learn songs from their fathers. We are active and noisy during the day, like birds, and we can also be territorial. Also like birds, we try to attract mates through colorful displays and beautiful songs. Birds are sensitive to pollution in their environment just like we are: harmful elements such as mercury wreak similar havoc on human and bird biology alike. Because our species share so many attributes, studying birds illustrates the connections between them and us.
Mountain pine beetle threatening high-altitude, endangered trees
(01/02/2013) In the western U.S., few trees generally grow in higher altitudes than the whitebark pine (Pinus albicaulis). Providing shelter and food for bears, squirrels and birds, the whitebark pine ecosystems also help regulate water flow from snowmelt. But, according to a new study in the Proceedings of the National Academy of Sciences (PNAS), climate change has produced a novel threat for these high-altitude forests : mountain pine beetles (Dendroctonus ponderosae).
Rainforests teem with insects, most of which are unknown, finds study
(12/13/2012) Researchers in Panama have published the results of the most comprehensive survey of arthropods in a small area of tropical rainforest. At a high level, the findings surprise no one: the Panamanian rainforest is full of insects, spiders, and crustaceans. Yet the results also show how little is known about this large group of organisms — 60-70 percent of the species are thought to be new to science.
New species of bioluminescent cockroach possibly already extinct by volcanic eruption
(11/14/2012) While new species are discovered every day, Peter Vršanský and company's discovery of a light-producing cockroach, Lucihormetica luckae, in Ecuador is remarkable for many reasons, not the least that it may already be extinct. The new species represents the only known case of mimicry by bioluminescence in a land animal. Like a venomless king snake beating its tail to copy the unmistakable warning of a rattlesnake, Lucihormetica luckae's bioluminescent patterns are nearly identical to the poisonous click beetle, with which it shares (or shared) its habitat.
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.
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.
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.
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.
Private reserve safeguards newly discovered frogs in Ecuadorian cloud forest
(08/28/2012) Although it covers only 430 hectares (1,063 acres) of the little-known Chocó forest in Ecuador, the private reserve las Gralarias in Ecuador is home to an incredible explosion of life. Long known as a birder's paradise, the Reserva las Gralarias is now making a name for itself as a hotspot for new and endangered amphibians, as well as hundreds of stunning species of butterfly and moth. This is because the reserve is set in the perfect place for evolution to run wild: cloud forest spanning vast elevational shifts. "The pacific slope cloud forests [...] are among the most endangered habitats in the world," explains Reserva las Gralarias' founder, Jane Lyons, in a recent interview with mongabay.com.
Scientists discover beautiful new insect species after stumbling upon photos on Flickr
(08/09/2012) Scientists have discovered a previously unknown species of lacewing insect after stumbling upon a series of photos posted on Flickr®, according to a paper published in the journal ZooKeys.
'The lion of the cave:' new predatory, swimming cricket discovered in Venezuela
(08/06/2012) Scientists have discovered what is likely a new species of cricket that is the top predator of its lightless world: a cave in a Venezuelan tepui. The fauna of cave was documented by BBC filmmakers as researchers uncovered not only a large, flesh-eating cricket but a new species of catfish.
NASA images reveal massive forest die-off from tiny beetle
(07/31/2012) Satellite images highlighted by NASA this week reveal a massive forest die-off in Colorado due to severe pine park beetle infestations.
Predicting the distribution of tropical dung beetles
(07/09/2012) Although they live in almost every ecosystem in the world—from your backyard to the Antarctic—scientists know very little about many insect species, including many individual species' distribution. A new study in mongabay.com's open-access journal Tropical Conservation Science attempts to predict the range of 53 dung beetle species in the genus Eurysternus, all of which are found in the American tropics. Dung beetles are hugely important to their environments, since they efficiently devour and recycle waste.
New species threatened by mining dubbed the 'Avatar moth'
(06/19/2012) A new species of moth has been named after one of the world's most popular movie blockbusters: Avatar. Discovered on New Zealand's Denniston Plateau during a biodiversity survey by local NGO Forest & Bird this March, the new moth species is imperiled by plans for a coal mine on the plateau. The name—Avatar moth (Arctesthes avatar)—was chosen by its discoverers from a list of almost 100 entries by the public.
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).
Campaign targets Bayer on mass bee die-offs
(04/06/2012) A campaign launched on Change.org is calling on the EPA to ban chemicals known as neoniconitoids after two prominent studes linked the pesticide to mass Colony Collapse Disorder among bees.
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.
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.
Photo: new cookies-and-cream insect surprises researchers in Belize
(02/21/2012) Scientists have discovered the first ever insect in the Ripipterygidae family in Belize. Measuring only 5 millimeters (0.19 inches), the tiny insect uses its powerful legs to leap away from predators much like a grasshopper.
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).
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.
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.
