In Thursday’s issue of the journal Science, two teams of researchers published studies suggesting that low levels of a common pesticide can have significant effects on bee colonies. One experiment, conducted by French researchers, indicates that the chemicals fog brains, making it harder for them to find their way home. The other study, by scientists in Britain, suggests that they keep bumblebees from supplying their hives with enough food to produce new queens. The authors of both studies contend that their results raise serious questions about the use of the pesticides, known as neonicotinoids. “I personally would like to see them not being used until more research has been done,” said David Goulson, an author of the bumblebee paper who teaches at the University of Stirling, in Scotland. “If it confirms what we’ve found, then they certainly shouldn’t be used when they’re going to be fed on by bees.” Bees’ Decline Linked to Pesticides, Studies Find

Zoologger is our weekly column highlighting extraordinary animals – and occasionally other organisms – from around the world Species: Mesodinium chamaeleonHabitat: seawater around Scandinavia and North America, chowing down on a new generation of slaves Many animals transform themselves almost beyond recognition in the course of their lives. Caterpillars become butterflies and tadpoles become frogs, and if we couldn't watch them do so we might not even suspect that the two stages were the same creature. Spectacular as these shifts are, they are only shape-shifting. Zoologger: Unique life form is half plant, half animal - life - 13 January 2012
Some animals, like turtles, can live for decades. But most turtle studies only last a few years (one big reason is that many studies are conducted by graduate students and, contrary to popular belief, students do in fact want to graduate quickly). So, because turtles live for decades and most studies are completed after just a couple years, that means that much of what we know about these animals is based on snapshots in time. Since many of us want to know best how to conserve turtle populations, it is important that we have a better understanding about how they change over time. Knowing how populations naturally fluctuate allows us to better understand how they might respond to conservation threats. Establishing this baseline data is particularly important for undisturbed populations. Living Alongside Wildlife: Trapping Tropical Turtles Today
When Atlantic cod stocks went into freefall through the 1980s, while grey seal populations were simultaneously exploding, it has long seemed to Canadian fishermen that there must be a link between the two: that the seals have been eating the fish, and that the 20-year moratorium on the Northern cod fishery was a solution that did not fit the problem. The failure of the cod to rebound even without an active fishery has only bolstered that theory. Yet, all official research seemed to disprove it, with field studies pointing to other unexplained causes of cod mortality, and the limited influence of seals. But now, a study has found that grey seals — top predators that can weigh as much as a bear — do in fact eat a lot of cod, and are largely responsible for the fish’s decline. The finding, published in the journal Fisheries Research, is sure to stoke the controversy over a proposed government cull of a quarter million grey seals for the benefit of cod. Atlantic cod study renews debate over grey seal cull

HAL lives, breathes, is infected with toxins Thomas Knudsen carefully poisons a 3-week-old human embryo with a dose of isoretinoin. Isoretinoin, more commonly known as the acne medication Accutane, is highly toxic, a known cause of birth defects. It prevents vitamin A from signaling to the brain that it’s time for the limbs to start growing. Babies exposed to it during a critical time in development are born with shortened arms and legs.
The U.S. Fish and Wildlife Service (FWS) this week granted the Ozark hellbender (Cryptobranchus alleganiensis bishopi) protection under the Endangered Species Act (ESA) but made the unusual decision not to declare critical habitat for the rare, giant salamanders because, it said, doing so could open it to threats from those who would illegally collect the species for the international pet trade. Ozark hellbenders are North America’s largest amphibians, often topping off at 60 centimeters in length, and because of that size they are highly valued by collectors. A study published in Applied Herpetology in 2007 found evidence of rampant illegal hellbender collection between 1969 and 1989, including 171 individuals collected during one September weekend in 1980. The study blamed the illegal pet trade as one of the major factors in the 75 percent decline of Ozark hellbender populations over the past few decades.

Zoonotic Viruses Found in Seized Wildlife - in Infectious Disease, General Infectious Disease from MedPage Today Bushmeat and other illegally imported wildlife confiscated at U.S. ports can harbor zoonotic viruses, researchers found. A pilot screening program conducted largely at New York's John F. Kennedy International Airport (JFK) identified several pathogens, including simian foamy virus and herpesviruses, among non-human primate products attempted to be smuggled into the country, Kristine Smith, PhD, of the Wildlife Conservation Society in New York City. "Although the findings to date are from a small pilot study, they remind us of the potential public health risk posed by illegal importation of wildlife products -- a risk we hope to better characterize through expanded surveillance at ports of entry around the country," Smith said in a statement.

Natalie Heng The Star 20 Dec 11; FOR a wild flower, being desirable is a recipe for disaster. The seductiveness and allure of many orchid species have cost them, dearly. Centuries of plunder have contributed to many species teetering on the brink of extinction. Many are endangered, and a good number have already been wiped off the planet. Some rare species still exist, but only in the closely guarded sanctuaries of private collections or public botanic gardens. Malaysian orchids: The curse of beauty
Guide reveals Amazon's biological bounty Mark Kinver BBC News 20 Dec 11; The UN has co-produced a study that lists scientific details of Amazon plant species that can be harvested for economic or medicinal purposes. It is estimated that 80% of people in developing nations depend on non-wood forest products, such as fruit, for nutrition and medicine. The publication aims to help bridge the gap in knowledge between scientists and local people, the authors have said. The publication coincides with the end of the International Year of Forests.
Seized RM3.9 million pangolins likely also from Sabah | Daily Express Newspaper Online, Sabah, Malaysia. Seized RM3.9 million pangolins likely also from Sabah Kota Kinabalu: Sabah Customs has not ruled out the possibility that the 5,000kg of frozen pangolin meat seized in Sandakan last week, may have originated from Sabah islands, Sarawak or neighbouring countries. Its Acting Director Dr Janathan Kandok said the department suspected Sandakan is the collection centre before the suppliers meet up and smuggle it out of Sabah. "In the latest case, over 1,000 packets of frozen pangolin meat were seized from a 40-foot long boat at Batu Sapi waters near Kg Bahagia at about 6.30pm on Dec. 7. "This pangolin meat is believed to have medicinal benefits especially for men and it is being sold at RM800 per kg in the international market and RM150 per kg in the local market," he told Daily Express, Monday.

Prime Indonesian Jungle To Be Cleared For Palm Oil Jakarta Globe 9 Dec 11; Aceh. The man known as Indonesia's "green governor" chases the roar of illegal chainsaws through plush jungles in his own Jeep. He goes door-to-door to tell families it's in their interest to keep trees standing. That's why 5,000 villagers living the edge of a rich, biodiverse peat swamp in his tsunami-ravaged Aceh province feel so betrayed. Their former hero recently gave a palm oil company a permit to develop land in one of the few places on earth where orangutans, tigers and bears still can be found living side-by-side — violating Indonesia's new moratorium on concessions in primary forests and peatlands.
