Living Alongside Wildlife: Trapping Tropical Turtles Today. 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. Atlantic cod study renews debate over grey seal cull. 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. How I became we, which became I again. Most life on Earth exists as single cells.
But the ones comprised of many cells, from the tiniest ant to the tallest tree, have had an undeniable impact on our planet. These ‘multicellular’ creatures evolved from single-celled ancestors at least 25 times throughout Earth’s history.

Hellbender Salamander Gets Endangered Species Designation, but No Habitat Protection—and That May Be a Good Thing. 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.
Currently, there's minimal surveillance of imported wildlife -- even that which is legally imported -- despite the fact that the U.S. brings in more animals than any other country. The study was supported by the V. MOST READ IN Infectious Disease false. Www.iias.nl/nl/35/IIAS_NL35_10.pdf. Top Five Uses of Social Media in Education.

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.

Artificial meat grown in vats may be needed if the 9 billion people expected to be alive in 2050 are to be adequately fed without destroying the earth, some of the world's leading scientists report today. But a major academic assessment of future global food supplies, led by John Beddington, the UK government chief scientist, suggests that even with new technologies such as genetic modification and nanotechnology, hundreds of millions of people may still go hungry owing to a combination of climate change, water shortages and increasing food consumption.
In a set of 21 papers published by the Royal Society, the scientists from many disciplines and countries say that little more land is available for food production, but add that the challenge of increasing global food supplies by as much as 70% in the next 40 years is not insurmountable.
