(03/02/2011) As everyone knows, human zombies are created when an uninfected human is bitten by a member of the brain-craving undead. But what about ant zombies? Yes, that's right: ant zombies.
Meat producers should replace cattle with insects, scientists say
(01/10/2011) Scientists in the Netherlands have discovered that insects produce significantly less greenhouse gas per kilogram of meat than cattle or pigs. Their study, published in the online journal PLoS One, suggests that a move towards insect farming could result in a more sustainable - and affordable - form of meat production.
U.S. bumble bees experiencing significant declines
(01/04/2011) Many US bumble bee populations have declined significantly over the past few decades, with certain species dropping off by as much as 96%. While the decline is linked to low genetic diversity and disease, an underlying cause remains uncertain.
How cannibal crickets choose their victims
(12/17/2010) Social interactions influence cannibalistic behavior among migratory bands of crickets, finds a new study published in the Public Library of Science. Cannibalism in turn is a major driving force behind the nature and direction of cricket swarms.
Flight of the Monarchs Reveals Environmental Connections across a Continent
(11/08/2010) As autumn settles across North America, one hallmark of the season is the gentle southward flight of the Monarch Butterflies as they migrate towards the forests that shelter their species during the winter months. Unfortunately, as with other forests across the planet, the Monarch's "over- wintering grounds" in Mexico are suffering from increased human pressures. An innovative conservation group called the ECOLIFE Foundation has stepped up to help safeguard the Monarch's winter forests, and in the process discovered that addressing the Monarch's plight came only after uncovering connections that bind us all. The following article is an interview with Bill Toone, the Executive Director of ECOLIFE.
Photos: ants take top prize at Veolia Wildlife Environment Photography contest
(10/21/2010) An image of nocturnal ant silhouettes systematically devouring a leaf in Costa Rica has given Hungarian photographer, Bence Máté, the much-coveted Veolia Wildlife Environment Photographer of the Year award. In addition to being named Photographer of the year, Máté also won the Erik Hosking award, given to a young photographer (ages 18-26) for a portfolio of images, for images taken in Costa Rica, Brazil, and Hungary.
Monarch butterflies medicate their sick kids
(10/12/2010) A new study in Ecology Letters has discovered that monarch butterflies employ medicinal plants to treat their larva. Researchers found that certain species of milkweed, which the larva feed on, can reduce the threat of a sometime deadly parasite. However, even more surprising: "we have also found that infected female butterflies prefer to lay their eggs on plants that will make their offspring less sick, suggesting that monarchs have evolved the ability to medicate their offspring," says lead author Jaap de Roode.
Photos: 200 new species discovered in 60-day expedition in New Guinea
(10/06/2010) A 2009 expedition to Papua New Guinea proves once again that the island-nation is as diverse in life as it is in human cultures. It took researchers with Conservation International (CI) and the local Institute for Biological Research (IBR) just two months to uncover a startling 200 new species: averaging more than 3 a day in the remote Nakanai Mountains and Muller Range rising from the island of New Britain, a part of Papua New Guinea. Half of the new species were spiders, but the team also found two new mammals, nine new plants, two dozen frogs, and multitude of insects. Most surprising was the discovery of at least two species so unique that they are likely to be assigned their own genus.
The effect of forest regeneration strategies on beetles
(09/27/2010) As conservationists attempt to find the best way to re-establish forests in abandoned areas, a new study in the open-access journal Tropical Conservation Science compares the impacts on bess beetles of different method to regeneration forest. Bess beetles are important dead wood-recyclers in the forest. Looking at three different forests in the Colombian Andes—natural regeneration, monoculture reforestation, and an old-growth forest as a baseline—researchers found that old-growth and natural regeneration had the highest diversity of bess beetles, while old-growth sported the greatest abundance of beetles.
How the overlooked peccary engineers the Amazon, an interview with Harald Beck
(09/20/2010) When people think of the Amazon rainforest, they likely think of roaring jaguars, jumping monkeys, marching ants, and squeezing anacondas. The humble peccary would hardly be among the first animals to cross their mind, if they even know such pig-like animals exists! Yet new research on the peccary is proving just how vital these species are to the world's greatest rainforest. As seed dispersers and seed destroyers, engineers of freshwater habitats and forest gaps, peccaries play an immense, long overlooked, role in the rainforest. "Peccaries have the highest density and biomass of any Neotropical mammal species. Obviously these fellows have quite an appetite for almost anything, but primarily they consume fruits and seeds. Their specialized jaws allow them to crush very hard seeds. The cracking sounds can be heard through the thick vegetation long before we could see them. As peccary herds bulldoze through the leaf litter in search for insects, frogs, seeds, and fruits, they destroy (i.e. snap and trample) many seedlings and saplings, sometimes leaving only the bare ground behind," Harald Beck, assistant professor at Towson University in Maryland, told mongabay.com in an interview.
Exploring Kenya's sky island
(08/18/2010) Rising over 2,500 meters from Kenya's northern desert, the Mathews Range is a sky island: isolated mountain forests surrounded by valleys. Long cut off from other forests, 'sky islands' such as this often contain unique species and ecosystems. Supported by the Nature Conservancy, an expedition including local community programs Northern Rangelands Trust and Namunyak Conservancy recently spent a week surveying the mountain range, expanding the range of a number of species and discovering what is likely a new insect.
Logged forests retain considerable biodiversity in Borneo providing conservation opportunity
(08/12/2010) A new study in the Proceedings of the Royal Society B finds that forests which have undergone logging in the past, sometimes even twice, retain significant levels of biodiversity in Borneo. The researchers say these findings should push conservationists to protect more logged forests from being converted into oil palm plantations where biodiversity levels drop considerably and endangered species are almost wholly absent. Given that much of Borneo's forests have been logged as least once, these long-dismissed forests could become a new frontier for conservationists.
Eleven new species discovered in France
(07/29/2010) Usually announcements of new species come from biodiverse rainforests or unexplored marine depths, but researchers have announced the discovery of nearly a dozen new species in one of Earth's most well-trodden place: France. Eleven new species have been discovered in Mercantour National Park in southern France. All the new species are insects, including one beetle, seven new aquatic invertebrate living under creek beds, and three springtails, which are soil-dwelling arthropods.
Uncovering the intelligence of insects, an interview with Lars Chittka
(06/29/2010) Many people would likely consider 'insect intelligence' a contradiction in terms, viewing insects—when they think of them as anything more than pests—as something like hardwired tiny robots, not adaptive, not intelligent, and certainly not conscious. However, research over the last few decades have shown that a number of well-studied insects are capable of performing amazing intellectual feats, from recognizing individuals to employing a symbolic language in a behavior known as a 'bee waggle'. "Already in 1900, Buttel-Reepen asked whether honeybees are mere reflex machines—and emphatically denied that claim," Dr. Lars Chittka, professor of Sensory and Behavioral Ecology at Queen Mary University in London, told mongabay.com in an interview. "Over the last century, we have seen a fundamental change in perspective on the learning capacities of insects, and there a now several credible lines of evidence that insects are capable of cognitive feats that had previously been ascribed only to 'higher' vertebrates".
Invertebrates in Brazilian traditional medicines
(06/28/2010) According to a new study in Tropical Conservation Science a surprising number of invertebrates are used in Brazilian traditional medicines, which are popular both in rural and urban areas. Researcher discovered that at least 81 species from five taxonomic groups are being used to treat a variety of illnesses in Brazil.
18,225 new species discovered in 2008
(05/27/2010) In the 2010 State of Observed Species researchers have announced that 18,225 living species were discovered in 2008. In addition, 2,140 new extinct species were discovered byway of fossils.
Children prioritize TV, video games over saving the environment
(05/18/2010) When asked to rank what was most important to them children across the world chose watching TV and playing video games ahead of saving the environment, according to an Airbus survey of 10,000 children, ages 5-18, from ten countries. Forty percent of children ranked watching TV and playing video games as most important to them, while 4 percent put 'saving the environment' as number one. Nine percent of the children said that protecting animals was most important to them.
Photos: more new species found in Indonesia's 'lost world'
(05/17/2010) The Foja Mountains on the Indonesian side of New Guinea have proven a biological treasure trove that just keeps spilling riches. Two-and-a-half years ago the region—dubbed Indonesia's 'lost world'—made news globally when researchers announced the discovery of a giant rat: five times the size of the familiar brown rat. New amphibians, birds, and insects have also been found during past expeditions in 2005 and 2007. A collaborative team of Indonesia and international researchers have since returned to the Foja Mountains and found more spectacular species.
How an agricultural revolution could save the world's biodiversity, an interview with Ivette Perfecto
(05/04/2010) Most people who are trying to change the world stick to one area, for example they might either work to preserve biodiversity in rainforests or do social justice with poor farmers. But Dr. Ivette Perfecto was never satisfied with having to choose between helping people or preserving nature. Professor of Ecology and Natural Resources at the University of Michigan and co-author of the recent book Nature’s Matrix: The Link between Agriculture, Conservation and Food Sovereignty, Perfecto has, as she says, "combined her passions" to understand how agriculture can benefit both farmers and biodiversity—if done right.
Scientists: 60 million USD needed to gauge the global threat to biodiversity
(04/08/2010) One of the greatest barriers to saving the world's biodiversity is simply a lack of knowledge: to date less than 50,000 species have been surveyed by the IUCN Red List regarding their threat level, while the vast majority of the world's species are left unanalyzed especially fungi, plants, fish, reptiles, and insects and other invertebrates. To address this problem, some of the world's top biologists have proposed a 60-million US dollar program they dub the 'barometer of biodiversity' to gather a representative sample of all taxons.
Scientists discover world's first amphibious insects: Hawaiian caterpillars
(03/22/2010) Scientists have never before discovered a truly amphibious insect until now: writing in the Proceedings of the National Academy of Sciences researchers have announced the discovery of 12 species of Hyposmocoma moths in the Hawaiian islands which they consider truly amphibious—that is a species able to survive both on land and underwater indefinitely.
Why seed dispersers matter, an interview with Pierre-Michel Forget, chair of the FSD International Symposium
(03/07/2010) There are few areas of research in tropical biology more exciting and more important than seed dispersal. Seed dispersal—the process by which seeds are spread from parent trees to new sprouting ground—underpins the ecology of forests worldwide. In temperate forests, seeds are often spread by wind and water, though sometimes by animals such as squirrels and birds. But in the tropics the emphasis is far heavier on the latter, as Dr. Pierre-Michel Forget explains to mongabay.com. "[In rainforests] a majority of plants, trees, lianas, epiphytes, and herbs, are dispersed by fruit-eating animals. […] As seed size varies from tiny seeds less than one millimetres to several centimetres in length or diameter, then, a variety of animals is required to disperse such a continuum and variety of seed size, the smaller being transported by ants and dung beetles, the larger swallowed by cassowary, tapir and elephant, for instance."
Website seeking 'most wanted' photos and videos of vanishing species
(03/04/2010) Many of the world's most endangered species have never been photographed or caught on film. The not-for-profit website ARKive is hoping to change that. ARKive provides a collection of some of the best photos and video clips of the world's species.
Oil palm plantations support fewer ant species than rainforest
(03/02/2010) Oil palm plantations support substantially less biodiversity than natural forests when it comes to ant species, reports new research published in Basic and Applied Ecology. Tom Fayle, a University of Cambridge biologist, and colleagues sampled ant populations in Danum Valley Conservation Area, a rainforest, and nearby oil palm plantations in Sabah, a state Malaysian Borneo. The researchers counted 16,000 worker ants from 309 species in the natural forest but only in 110 species at the oil palm plantation.
Cricket mothers warn offspring about spiders before they hatch
(02/21/2010) Cricket mothers are long gone by the time their infants hatch, so one would assume that cricket parents have little effect on their offspring's behavior. Not so, according to a new study in the American Naturalist which proves that mother crickets have the potential to teach their offspring—while still in their eggs—about the hazards of spiders.
Where two worlds collide: visiting Tabin Wildlife Reserve
(02/21/2010) The vehicle stopped on the way into Tabin Wildlife Reserve as a troupe of pig-tailed macaques began making their way across the road. In a flash a domestic dog, which may or may not have been 'ownerless', ambushed the group. Chaos erupted as the big predator fell upon the community. As quickly as it began it was all over and the dog was rushing over with an infant monkey in its mouth, leaving the macaques' screeching out their helplessness. As my uncustomary welcome to Tabin Wildlife Reserve shows: the park is a meeting of two worlds. On the left side of the road leading into the reserve is a massive oil palm plantation, on the right is the rainforest and the many species the reserve protects. Tabin, therefore, gives the visitor a unique up-close view of the debate raging in Borneo and throughout much of Southeast Asia over conservation and environment versus oil palm plantations.
Sophisticated flying methods allow insects to hitchhike on fast winds
(02/04/2010) Researchers have long been fascinated by how insects migrate thousands of kilometers, for example from Britain to the Mediterranean. A new study, published in Science shows that although tiny, insects are not at the mercy of winds as expected. Instead they employ sophisticated flight behaviors to use fast winds to their advantage.
Loss in biodiversity may be killing bees
(01/20/2010) A decline in diverse plants species on which to feed may be causing a similar decline in bee survival, according to a new paper in Biology Letters.
Photos: park in Ecuador likely contains world’s highest biodiversity, but threatened by oil
(01/19/2010) In the midst of a seesaw political battle to save Yasuni National Park from oil developers, scientists have announced that this park in Ecuador houses more species than anywhere else in South America—and maybe the world. "Yasuní is at the center of a small zone where South America's amphibians, birds, mammals, and vascular plants all reach maximum diversity," Dr. Clinton Jenkins of the University of Maryland said in a press release. "We dubbed this area the 'quadruple richness center.'"
UK planning to reintroduce insects
(01/17/2010) When one thinks of reintroducing wildlife, one usually thinks of big charismatic mammals, such as wolves or beaver, or desperate birds like the Californian condor. But the Royal Society for the Protection of Birds in Scotland is going one step further to save its unique ecology with plans to reintroduce four species of dwindling insects.
Forgotten species: discovering the shimmer of Maathai's Longleg
(01/13/2010) Few species receive less respect and less conservation attention than insects. This despite the fact that they are some of the most diverse species on the planet andthey provide a number of essential services to humankind, including pollination, pest control, production (for example honey and silk), waster recycling, and indications of habitat health. Scientists are not only unsure just how many species of insects are threatened in world; they are equally uncertain how many insects exist. Currently there are nearly a million insect species described by science, but millions more likely exist. It's probable that innumerable insect species have vanished before even being catalogued by entomologists.
World of Avatar: in real life
(01/13/2010) A number of media outlets are reporting a new type of depression: you could call it the Avatar blues. Some people seeing the new blockbuster film report becoming depressed afterwards because the world of Avatar, sporting six-legged creatures, flying lizards, and glowing organisms, is not real. Yet, to director James Cameron's credit, the alien world of Pandora is based on our own biological paradise—Earth. The wonders of Avatar are all around us, you just have to know where to look.
Researchers catch new cricket species going where no cricket has gone before
(01/13/2010) East of Madagascar, on the small island of Reunion, researchers have made a remarkable discovery: a cricket that pollinates an orchid. The cricket, which is also a species new to science, was caught by a motion sensitive camera pollinating the orchid, Angraecum cadetii. The genus Angraecum orchid is usually pollinated by moths, but cadetti's nectar-spur opening is just the right shape for the cricket, known as the 'raspy cricket'.
Housing developments choking wildlife around America's national parks
(01/05/2010) Housing developments within 50 kilometers (31 miles) of America's national parks have nearly quadrupled in sixty years, rising from 9.8 million housing units to 38 million from 1940 to 2000. The explosion of housing developments adjacent to national parks threatens wildlife in a variety of ways, according to a new study in the Proceeding of the National Academy of Sciences (PNAS). "We are in danger of loving these protected areas to death," says co-author Anna Pidgeon as assistant professor at the University of Wisconsin-Madison.
Governments, public failing to save world's species
(11/04/2009) According to the International Union for the Conservation of Nature's (IUCN) 2008 report, released yesterday, 36 percent of the total species evaluated by the organization are threatened with extinction. If one adds the species classified as Near Threatened, the percentage jumps to 44 percent—nearly half.
The faster, fiercer, and always surprising sloth, an interview with Bryson Voirin
(10/25/2009) Sloths sleep all day; they are always slow; and they are gentle animals. These are just some of the popular misconceptions that sloth-scientist and expert tree-climber, Bryson Voirin, is overturning. After growing up among the wild creatures of Florida, spending his high school years in Germany, and earning a Bachelors degree in biology and environment at the New College of Florida, Voirin found his calling. At the New College of Florida, Voirin "met Meg Lowman, the famous canopy pioneer who invented many of the tree climbing techniques everyone uses today."
Arctic lake undergoing unprecedented changes due to warming
(10/19/2009) The Arctic should be growing cooler, but a new sediment core taken from an Arctic lake reveals that the lake's ecology and chemistry has been transformed by unnatural warming beginning in the 1950s. The sediment core proves that changes happening in the lake during the Twentieth Century are unprecedented over the past 200,000 years. Headed by University of Colorado scientist Yarrow Axelford, the study retrieved the sediment core from the bottom of a thirty foot deep lake on Baffin Island. Importantly the sediment core goes back 80,000 years further than any other core retrieved from the Greenland ice sheet, providing researchers with the longest timescale yet of changes in the Arctic climate.
New species everywhere in Papua New Guinea's 'lost' volcano
(09/07/2009) A five week expedition into a remote extinct volcano has uncovered a treasure trove of new species in Papua New Guinea, including what may be the world's largest rat, a fanged frog, and a grunting fish. In all the expedition estimates it may have found around forty species unknown to science. The expedition was undertaken by a BBC film crew and scientists in January. Local trackers led them into the unexplored jungle, hidden beneath the Bosavi volcano's 2,800 meter summit. Six months prior to arrival, fields of spinach and sweet potato were planted to feed the expedition in such a remote area.
A new effort to save global biodiversity? Just ask E.O. Wilson
(08/24/2009) In a short interview with New Scientist, world renowned entomologist, conservationist, and author, E.O. Wilson speaks about his latest idea to save the world's biodiversity.
Moths defend against bats by 'jamming' sonar
(07/16/2009) Researchers have discovered a species of tiger moth that eludes bats by jamming their echolocation with ultrasonic clicks, a discovery that adds to the list of defensive mechanisms that insects use to defend themselves against bats. The study is published in the journal Science.
Dragonflies migrate 14,000-18,000 km from India to S. Africa
(07/16/2009) Millions of dragonflies migrate thousands of kilometers across the Indian Ocean from southern India to Africa, reports the BBC.
First comprehensive study of insect endangerment: ten percent of dragonflies threatened
(06/23/2009) A lot of time, effort, and funds have been spent on programs evaluating the threat of extinction to species around the world. Yet insects have not benefited from these programs, which have largely focused on more 'charismatic' species such as mammals, birds, amphibians, and reptiles. This gap is clearly shown by the fact that 42 percent of vertebrates have been assessed by the International Union for the Conservation of Nature (IUCN), and only 0.3 percent of invertebrates.
Photos: treasure trove of new species discovered in Ecuador
(06/16/2009) Near the once-contentious border of Ecuador and Peru in the mountainous forests of the Cordillera del Condor, scientists from Conservation International (CI) conducted a Rapid Assessment Program (RAP), uncovering what they believe are several new species, including four amphibians, one lizard, and seven insects. The team focused on the Upper Nanharitza River Basin, which has been geologically isolated from the rest of the Andes, giving it broad potential for new species.
Photo: brilliant pink moth discovered in Arizona
(06/11/2009) A new species of moth with brilliantly-colored pink wings has been discovered at 7,700 feet in the Chiricahua Mountains of southern Arizona. "This large moth flew in and we didn't think much of it because there is a silk moth very much like it, a Doris silk moth that feeds on pines that has dark wings with pink on the hind wings. It's fairly common there," said University of Arizona biologist, Bruce Walsh, who discovered the species.
The unknown role of coextinctions in the current extinction crisis
(05/28/2009) Scientists have long recognized ‘coextinctions’ as a major concern when it comes to the current mass extinction crisis. Despite such recognition, however, the role of coextinctions remains largely mysterious and little-studied. A new paper attempts to address this by settling what is known (and unknown) about the phenomenon of coextinctions and where research needs to go next.
Photos: top 10 species discovered in 2008
(05/22/2009) Scientists documented 18,516 previously unknown species in 2007, report researchers from the International Institute for Species Exploration at Arizona State University, who also unveiled the "top 10 new species" described in 2008. The "top 10" species include a pea-sized seahorse, caffeine-free coffee, bacteria that live in hairspray, a tiny snake, a two foot long insect from Malaysia, a fossilized specimen of the oldest known live-bearing vertebrate, a snail whose shell twists around four axes, a ghost slug from Wales, a deep blue damselfish, and a palm that flowers itself to death.
Assessing Tropical Butterfly Communities When Time Is Short
(03/23/2009) Butterflies can be used to quickly assess the conservation value of an area, report researchers writing in the journal Tropical Conservation Science. Timothy Bonebrake of Stanford University and Rubén Sorto of SalvaNATURA managed to sample 40-60% of the butterfly community in Playa El Icacal, El Salvador in just nine days. In the process, they identified areas in the region that hold the most conservation value.
Tropical forest tree is source of new mosquito repellent as effective as DEET
(02/05/2009) Isolongifolenone, a natural compound found in the Tauroniro tree (Humiria balsamifera) of South America, has been identified as an effective deterrent of mosquitoes and ticks, report researchers writing in the latest issue of Journal of Medical Entomology.
Butterfly tricks ants by mimicking their queen’s vocalizations
(02/05/2009) With cohesive hierarchical societies and a number of communication techniques, ants have been able to conquer a wide variety of ecosystems with great success. However, according to a recent paper in Science ants’ highly structured society at times comes with a price. A number of insects have evolved means to covertly infiltrate the ants’ society and live off their work and bounty by closely mimicking various ant communication methods. While scientists believe that these parasitical insects largely mimic ant communications like chemical exchange and physical contact—such as touching antennae—the study, however, discovered a butterfly which succeeds in infiltrating the highest echelons of ant society by vocalizing like a queen.
The honeybee can count
(01/29/2009) Plato once said: “numbers are the highest degree of knowledge: it is knowledge itself.” By Plato’s standards researchers have just discovered that the honey bee is a knowledgeable insect indeed. The honey bee can count to three in an instant according to a new study in the online journal PLoS ONE. Using dots and other abstract symbols, scientists from the Vision Centre in Australia tested whether the honey bees had the ability to count items in their environment.
