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.


Symposium tackles big question: how many species will survive our generation

(01/16/2009) Nine scientists dusted off their crystal balls Monday at the National Museum of Natural History in Washington DC, weighing in on the future of the world’s tropical forest. Despite the most up-to-date statistics, prognosis for the future of tropical forests varied widely. In the last few years a schism has occurred among biologists regarding the future of the tropics. No tropical scientist denies that rainforests and the species which inhabit them face unprecedented threats; neither do they argue that some of these forested regions and species will likely not survive the next fifty years. What has sparked debate, sometimes heated, is how bad will is it really? When the dust settles, what percentage of species will survive and how much forest will remain?


Infecting mosquitoes with parasite could reduce dengue fever outbreaks

(01/05/2009) With an average of 50 million cases worldwide dengue fever is second only to malaria in terms of concern for mosquito-borne illnesses. Carried primarily by the mosquito species Aedes aegypti, the fever is usually not fatal; however a particular strain of disease can be especially dangerous to children. However, early this year new research brings hope to the tropical areas where dengue fever is prevalent. Scientists have discovered a new possibility in debilitating the mosquitoes carrying dengue fever: the Wolbachia parasite.


Photos: Google Earth used to find new species

(12/22/2008) Scientists have used Google Earth to find a previously unknown trove of biological diversity in Mozambique, reports the Royal Botanic Gardens in Kew. Scouring satellite images via Google Earth for potential conservation sites at elevations of 1600 meters or more, Julian Bayliss a locally-based conservationist, in 2005 spotted a 7,000-hectare tract of forest on Mount Mabu. The scientifically unexplored forest had previously only been known to villagers. Subsequent expeditions in October and November this year turned up hundreds of species of plants and animals, including some that are new to science.


Corn expansion is hurting ladybugs

(12/15/2008) Expansion of corn acreage to meet ethanol targets is reducing the ability of beneficial insects to control pests, a loss valued at $58 million in the four states studied (Michigan, Iowa, Minnesota and Wisconsin), report researchers writing in the journal Proceedings of the National Academy of Sciences.


Insect intelligence: paper wasps display strong long-term memory

(12/01/2008) A recent study in Current Biology finds that paper wasps are capable of remembering rivals a week after initially meeting. As a highly social insect, the discovery proves that the paper wasps' social interactions are based on applied memory rather than simple instinct. The finding overturns many ideas about the intelligence of insects.


Invasive ant interferes with gecko's role in pollinating endangered plant

(11/28/2008) Invasive ants are destroying the symbiotic relationship between a colorful gecko and a critically endangered flower on the island of Mauritius, reports New Scientist citing research published by Dennis Hansen and Christine Müller in the journal Biotopica.

(10/09/2008) Climbing temperatures may doom many tropical species to extinction if they are unable to migrate to higher elevations or cooler latitudes, report researchers writing in Science.


Scientists discover 120 million year-old ant in the Amazon rainforest

(09/17/2008) Scientists have discovered a previously unknown species of ant in the Amazon that may shed light on the evolution of ants. The species is believed to be the oldest-known ant at around 120 million years old. The discovery is presented this week in the journal Proceedings of the National Academy of Sciences.


Pollination worth $216 billion/yr for food production

(09/16/2008) Pollination services provided by insects are worth $216 billion (€153 billion) a year reports a new study published in Ecological Economics. The figure represents about 9.5 percent of the total value of world agricultural food production.


For Australian beetles bigger is better; while American beetles don't care about size

(09/03/2008) Researchers have discovered a dung beetle that may be evolving into separate species in a few decades rather than thousands or millions of years. Separated geographically, sub-populations of the species show large differences in the size of their genitalia and horns. Such distinctions could create new species in a short time, because beetles with largely different genitalia cannot successfully mate.


Researchers discover "artistic" moth in Panama

(07/29/2008) Researchers have discovered a new species of Bagworm Moth that wraps its eggs individually in "beautiful cases" fashioned from its golden abdominal hairs, according to a new paper published in the Annals of the Entomology Society of America. The behavior is unique among insects.


The end of migrations: wildlife's greatest spectacle is critically endangered

(07/28/2008) If we could turn back the clock about 200 years, one could watch as millions of whales swam along their migration routes. Around 150 years ago, one could witness bison filling the vast America prairie or a billion passenger pigeons blotting out the sky for days. Only a few decades back and a million saiga antelope could be seen crossing the plains of Asia.


Leaf-cutter ants test theories about the Amazon's biodiversity

(07/23/2008) No one knows for certain how many insect species reside in the Amazon. One oft-quoted estimate is 30 million, but the actual number could be significantly lower or higher than this. Either way, biologists have long wondered why the richness of insect diversity in the Americas' tropical forests is exponentially higher than temperate forests. Three popular hypotheses have emerged—the theory of refugia, the marine incursion hypothesis, and the riverine barrier hypothesis. To test these theories a group of scientists, headed by Dr. Scott Solomon, studied three species of leaf-cutter ant species from the Amazon.


Implementing a butterfly farm: Iwokrama reserve's latest sustainable initiative

(07/20/2008) Iwokrama, which lies in the heart of Guyana's rainforest, is known worldwide for its innovative approach to preserving tropical rainforests and creating livelihoods for local communities. Their focus has been to create programs that utilize the forest sustainably, allowing for a mutual benefit between the people and the forest itself. Currently, Iwokrama has a number of initiatives under its umbrella, including eco-tourism, sustainable forestry, on-going research projects, and training programs. Amid these bustling projects, a new one has emerged: butterfly farming.


Pine beetles attack Canada, boosting GHG emissions

(07/10/2008) The mountain pine beetle, a small tree-devouring insect, has deforested an area of British Columbia the size of Louisiana — over 130,000 square kilometers. The 5 millimeter insect is a perfect tree-destroying machine. The beetles bore through the tree's bark to reach the phloem of the tree, which contains the tree's organic nutrients. The beetles then feed on these nutrients and lay their eggs. The trees defend themselves by secreting extra resin, but the beetles are often able to combat this by releasing a blue fungi. In about two weeks time, the tree turns a tell-tale red and essentially starves to death. The mountain pine beetles move on.


Colorful insects help search for anti-cancer drugs

(07/07/2008) Brightly-colored beetles or caterpillars feeding on a tropical plant may signal the presence of chemical compounds active against cancer and parasitic diseases, report researchers writing in the journal Frontiers in Ecology and the Environment. The discovery could help speed drug discovery.


Dung beetles persist in long-term forest fragments but may suffer from hunting of large animals

(06/09/2008) Dung beetles bury animal dung to use as their own food and to provide food for their young. This group of beetles is especially prevalent in tropical rainforests. Their burying behvaior incidentally contributes to ecosystem functioning and health by the removal of waste, control of dung-breeding pests, soil fertilization and aeration, and the secondary burial of intact seeds found in mammal feces. Because of their important roles in ecosystems, it is important to know how they are affected by habitat change, in this case, habitat fragmentation.

Global warming to increase insect attacks on plants

(02/11/2008) Global warming will increase attacks on plant leaves by insects, reports a study published in Proceedings of the National Academy of Sciences.


To reproduce, parasite transforms ant into juicy red berry

(01/17/2008) Scientists have discovered a parasite that transforms the appearance of its host, an ant, into that of a juicy red berry that birds are more likely to eat and disperse into new habitats, reports an article published in The American Naturalist. It is the first example of fruit mimicry caused by a parasite, say the researchers who discovered the parasite, a nematode or roundworm found in the canopy of tropical forests ranging from Central America to the lowland Amazon.


Disappearance of elephants, giraffes causes ecological chain reaction

(01/10/2008) The disappearance of elephants, giraffes and other grazing animals from the eastern African savanna could send ecological ripple effects all the way to the savanna's ants and the acacia trees they inhabit, warns a new study published in the journal Science.


Butterfly tricks ants into caring for its young

(01/03/2008) A species of butterfly in Denmark foolds ants into raising their larvae, reports research published in the journal Science.

(12/04/2007) Armed with a pair of tweezers and a handful of beetle droppings, University of Alberta forestry graduate Tyler Cobb has discovered why the bug-sized dung is so important to areas ravaged by fire.


Termites may produce cleaner biofuels

(11/23/2007) Termites may be the key to greener, more effective biofuels, report scientists writing in the November 22 edition of the journal Nature.


Billions of disappearing bees linked to virus

(09/06/2007) Scientists have linked the disappearance of tens of billions of bees to a virus, reports a study published in the 7 September issue of the journal Science. Colony collapse disorder (CCD), in which colonies inexplicably lose all of their worker bees, has been blamed for the loss of 50-90 percent of colonies in beekeeping operations across the U.S.


Stopping malaria using smell

(08/31/2007) Researchers have taken an important first step in developing improved repellants to protect mankind from its deadliest insect parasite: the mosquito.


Flies prefer Coke

(08/29/2007) While you may not catch a fly sipping Perrier, the insect has specialized taste cells for carbonated water that probably encourage it to binge on food with growing microorganisms. Yeast and bacteria both produce carbon dioxide (CO2) when they feast, and CO2 dissolves readily in water to produce seltzer or soda water.


Orchids may have co-existed with dinosaurs

(08/29/2007) Orchids are old enough to have co-existed with dinosaurs, report Harvard University scientists.


Vampire bats invade Finland thanks to global warming

(06/04/2007) Global warming has brought blood-sucking moths to Finland reports Reuters.


conservation biology needs to be accessible to the masses

(05/31/2007) Since its earliest days, when private collectors amassed great stores of specimens collected from the farthest reaches of the Earth, natural history studies often have been a pursuit of the economically well-off and of intellectually elitist scientists. One of the most important spinoffs of these natural history studies has been conservation Biology. Unfortunately, the culture of exclusivity appears to have also infected conservation Biology. Technical jargon, restricted access to data, and poor communication among researchers, amateur enthusiasts and political decision-makers have colluded to keep it a clubby affair that may be hurting goals of sustainable use of resources, long term management policies, and species and habitat conservation.


Army ants form living pothole plugs to speed up delivery

(05/27/2007) Certain army ants in the rainforests of Central and South America conduct spectacular predatory raids containing up to 200,000 foraging ants. Remarkably, some ants use their bodies to plug potholes in the trail leading back to the nest, making a flatter surface so that prey can be delivered to the developing young at maximum speed.


20-40% of U.S. bees have disappeared

(05/14/2007) Known and unknown ailments have killed 20 to 40 percent of bee colonies across the United States this winter according to a leading entomologist.


Mosquitoes are evolving in response to global warming

(04/23/2007) University of Oregon researchers studying mosquitoes have produced the first chromosomal map that shows regions of chromosomes that activate -- and are apparently evolving -- in animals in response to climate change


Tear-sucking moth in Madagascar feeds on bird eyes

(04/10/2007) Biologists have documented the first known case of moths feeding on the tears of birds. The research, published in the January 4 2007 issue of the journal Biology Letters, reports that Hemiceratoides hieroglyphica 'attacks sleeping birds in Madagascar' using its sharply barbed proboscis to penetrate the bird's eye. While similar behvaior has been reported in mammals, this is the first known case of tear-feeding on birds.


Antarctic insects make natual anti-freeze to survive cold

(04/02/2007) Insects in the some of the world's coldest places produce natural anti-freeze that enables them to survive sub-freezing temperatures for months on end according to research represented at the Society for Experimental Biology's Annual Meeting in Glasgow.
