(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.
