Beetles: nature's herbicide
(08/01/2011) New research in the Journal of Applied Ecology shows that ground beetles help farmers in the UK by devouring weed seeds before they can sprout. The researchers say the study finds another proof of how biodiversity—the multitude of species on Earth—provides 'free' ecosystem services for people.
Pictures of the day: pink animals
(07/25/2011) As a follow up to last week's popular "Unusually Blue Animals" post, here are some animals that are pretty in pink.
Picture of the day: unusually blue animals
(07/21/2011) Following up on yesterday's post on the spectacular blue anole from the Colombian island of Gorgona, here is a small collection of pure blue animals I've photographed. Birds and fish are excluded from the list since there are many blue species.
Photo: six new mini-moths discovered
(07/19/2011) Researchers have discovered six new species of moth from Central America, according to a new paper in Zoo Keys. The moths belong to the primitive Yponomeutidae family, which are commonly known as ermine moths, since some of the species' markings resemble the coat of the ermine.

Animal picture of the day: a cicada (like the one used in ice cream) in Oregon
(07/10/2011) Cicadas are insects found worldwide, including the United States. There are more than 2,500 species globally.
Photo: four new jewel beetles uncovered in Thailand and Indonesia
(07/10/2011) Researchers have discovered four new species of jewel beetles, one from Thailand and three from Indonesia. Jewel beetles, in the beetle family Bupretidae, are known for their iridescent colors.
Ant surprises on Murciélago Islands in Costa Rica
(06/28/2011) The Murciélago Islands are seven small islands off the northwest coast of Costa Rica in the Area de Conservación Guanacaste (ACG), home to one of the largest intact dry tropical forests in Central America. Despite this, few scientists have studied the biodiversity of these small uninhabited islands. A new study in the open access journal Tropical Conservation Science has attempted to rectify this gap by conducting the first survey of insects, specifically ants, on the islands. Researchers were surprised at the richness of ant species on the island: 50 species were documented, only two of which were invasive species.
Photos: 300 species discovered during expedition to Philippines
(06/26/2011) Scientists believe they have discovered more than new 300 species during a six-week expedition to the Philippines.
Dung beetles: a sewage SWAT team
(06/21/2011) Biology Professor Doug Emlen speaks with Laurel Neme on her 'The WildLife' radio show and podcast about the biology and armaments of dung beetles. An expert on the evolution and development of bizarre shapes in insects, Emlen notes that dung beetles are one of the 'kings' of odd morphology.
New bee species sports world's longest tongue
(06/14/2011) A new species of bee discovered in the Colombian rainforest could give the world's biggest raspberry! Researchers say the new bee has the longest tongue of any known bee, and may even have the world's longest tongue compared to body size of any animal: twice the length of the bee itself. The new species has been named Euglossa natesi in honor of bee-expert Guiomar Nates.
Photos: the top ten new species discovered in 2010
(05/23/2011) If we had to characterize our understanding of life on Earth as either ignorant or knowledgeable, the former would be most correct. In 250 years of rigorous taxonomic work researchers have cataloged nearly two million species, however scientists estimate the total number of species on Earth is at least five million and perhaps up to a hundred million. This means every year thousands of new species are discovered by researchers, and from these thousands, the International Institute for Species Exploration at Arizona State University selects ten especially notable new species.
The value of the little guy, an interview with Tyler Prize-winning entomologist May Berenbaum
(04/06/2011) May Berenbaum knows a thing or two about insects: in recognition of her lifelong work on the interactions between insects and plants, she has had a character on The X-Files named after her, received the Public Understanding of Science and Technology Award for her work in making science accessible to the public, and this year has been awarded the prestigious Tyler Environmental Prize. "Winning the Tyler Prize is an incredible honor—most of my scientific heroes have been Tyler Prize winners and I’m exceedingly grateful to be considered worthy of being included among their ranks," Berenbaum told mongabay.com in an interview. "The Prize is also tremendously enabling—because the money is unrestricted I can use it to carry out projects that have been difficult to fund."
Cloud forest dung beetles in India point to 'fossil ecosystem'
(03/28/2011) In the cloud forests and grasslands of India's Western Ghats, known as sholas, researchers have for the first time comprehensively studied the inhabiting dung beetle populations. The resulting study in mongabay.com's open access journal Tropical Conservation Science, has led scientists to hypothesize that the beetles in concordance with the sheep-like mammal, the nilgiri tahr (Nilgiritragus hylocrius), may be a sign of a 'fossil ecosystem'.
Climate change caused by deforestation triggers species migration
(03/23/2011) Local climate shifts caused by deforestation and land cover change are causing insects to migrate to higher — and cooler — habitats, reports a new study published in the journal Biotropica. The research has implications for predicting how species will respond to climate change.
New species of zombie-creating fungi discovered
(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.
