Any influenza-like signs in pigs should be reported

After the detection of the A/H1N1 virus in pigs in Canada transmitted by a human, FAO has again urged national authorities and farmers to carefully monitor pigs and investigate any possible occurrences of influenza-like symptoms in domestic animals.

"The human-to-animal transmission that occurred in Canada does not come as a surprise as influenza viruses are capable of transmitting from humans to animals," FAO's Chief Veterinary Officer Joseph Domenech said.

"The Canadian event should therefore not be a matter of panic, but it should remind us of the human-animal link in virus transmission on which we definitely need to keep an eye."

Influenza viruses, whether in humans or among animals, are constantly evolving genetically, along with changes in their ability to cause morbidity and mortality in humans or animals. Therefore the current A/H1N1 situation should be carefully monitored as many of the virus characteristics and developments are still unknown, Domenech said.

Surveillance for porcine respiratory disease should be intensified and all cases of porcine respiratory syndrome are recommended to be immediately reported to veterinary authorities. It is also recommended to inform OIE and FAO about any occurrence of outbreaks of the new A/H1N1 Influenza virus in pigs.

Strict biosecurity measures including restriction of movements of pigs, goods and people should be applied on all farms or holdings with swine showing signs of clinical respiratory illness until diagnosis of the illness has been made.

Where A/H1N1 influenza is confirmed, movement restrictions should be in force for seven days after the last animal has recovered. Governments are requested to provide full support in improving biosecurity measures particularly to small and medium pig farmers.

Persons who work directly with swine should be urged not to go to work if they have any signs of respiratory disease, fever or any influenza-like illness. Animal handlers and veterinarians should wear protective clothing to minimize the risk of being infected.


FAO stressed that there is absolutely no need to slaughter animals in view of preventing circulation of the A/H1N1 virus.

The agency emphasized that the A/H1N1 virus cannot be transmitted to humans by pork and pork products. Pork and pork products, handled in accordance with good hygienic practices recommended by the FAO/WHO Codex Alimentarius Commission and the OIE, will not be a source of infection.

New Species Of Big Cat Discovered In Tibet Fills Evolutionary Gap


The evolution of big cats has been nearly as mysterious as the cats themselves, but a new discovery will likely lead anthropologists to a better understanding of when and where big cats originated.

During a 2010 paleontological dig in Tibet, a husband-and-wife team who were part of a larger expedition discovered the fossilized partial remains of what appeared to be a type of cat. University of Southern California (USC) graduate Z. Jack Tseng and his wife Juan Liu made the discovery in the Zanda Basin near the border of Pakistan and China.

Tseng, who now works with the American Museum of Natural History (AMNH) in New York, said the discovery was a surprise. In a Smithsonian Magazine blog, Tseng explained that the team had been driving trail after trail in the Tibetan “badlands” before discovering a patch of fossils protruding from the ground on one particular hillside.

“In the little concentration of fossils, there were lots of limb bones from antelopes and horses obscuring everything else,” said Tseng. “It wasn’t until we started lifting things up, one by one, that we saw the top of a skull, and we thought, from the shape, that it looked something like a cat.”

Sea jellyfish threat in Australia

Sea jelly threat in AU. Warming waters and changing currents could bring a particularly dangerous species southward along Queensland coast.

Under changing ocean conditions, could more dangerous jellyfish be moving farther south?

Will venomous irukandji jellyfish reach south-east Queensland?

For the people of northern Australia, dangerous jellyfish stings are all too common. But under changing ocean conditions, could more of these dangerous jellyfish be moving farther south along the Queensland coast?

Increasing ocean temperatures and strengthening ocean currents are causing many marine species to migrate polewards. Among the species predicted to expand their distribution is the potentially deadly irukandji jellyfish, which are found in tropical regions around the world, including northern Queensland.

If these jellyfish do reach south-east Queensland waters, it could have a severe impact on local tourism and human health in coming generations.

Tyrant Dinosaur Evolution Tracks the Rise and Fall of Late Cretaceous Oceans


The Late Cretaceous (~95–66 million years ago) western North American landmass of Laramidia displayed heightened non-marine vertebrate diversity and intracontinental regionalism relative to other latest Cretaceous Laurasian ecosystems. Processes generating these patterns during this interval remain poorly understood despite their presumed role in the diversification of many clades. Tyrannosauridae, a clade of large-bodied theropod dinosaurs restricted to the Late Cretaceous of Laramidia and Asia, represents an ideal group for investigating Laramidian patterns of evolution. We use new tyrannosaurid discoveries from Utah—including a new taxon which represents the geologically oldest member of the clade—to investigate the evolution and biogeography of Tyrannosauridae. These data suggest a Laramidian origin for Tyrannosauridae, and implicate sea-level related controls in the isolation, diversification, and dispersal of this and many other Late Cretaceous vertebrate clades.

Connectivity of Tiger (Panthera tigris) Populations in the Human-Influenced Forest Mosaic of Central India

Today, most wild tigers live in small, isolated Protected Areas within human dominated landscapes in the Indian subcontinent. Future survival of tigers depends on increasing local population size, as well as maintaining connectivity between populations. While significant conservation effort has been invested in increasing tiger population size, few initiatives have focused on landscape-level connectivity and on understanding the effect different landscape elements have on maintaining connectivity.
We combined individual-based genetic and landscape ecology approaches to address this issue in six protected areas with varying tiger densities and separation in the Central Indian tiger landscape. We non-invasively sampled 55 tigers from different protected areas within this landscape. Maximum-likelihood and Bayesian genetic assignment tests indicate long-range tiger dispersal (on the order of 650 km) between protected areas.

Scientists discover rare new marine creatures

By Tony Field

Japanese and New Zealand scientists have discovered rare marine creatures living hundreds of metres below the ocean surface.

The research vessel Yokosuka has docked in Auckland, after exploring underwater mountains and volcanoes, about 1000 kilometres northeast of New Zealand.

Images recorded by the scientists show creatures they encountered 400 to 500 metres beneath the surface, some in areas containing active marine volcanoes along the Kermadec Trench.

Jellyfish news

More jellyfish blooms? The jury is still out but one researcher writes that it's possible due to loss of predators, pollutants, and global warming.

Are Ocean Conditions Ripe for a Jellyfish Takeover?

By Elizabeth Howell on Livescience.com

Data on jellyfish populations is making it hard to figure out if they are on the rise, and – if that rise is indeed happening – why it is so.

In 2000, a bloom of sea tomato jellyfish in Australia was so enormous — it stretched for more than 1,000 miles from north to south — that it was even visible from space. It was certainly a bloom that Australian jellyfish researcher Lisa-ann Gershwin won't forget.
