Help us save the mountain gorilla

News tips:

please read this interesting article posted by Sir David Attenborough on indiegogo.com

Sir David Attenborough: Help us save the mountain gorilla


Help us protect this Critically Endangered species & increase mountain gorilla numbers to over 1,000 individuals in the wild.

A personal plea from Fauna & Flora International (FFI) vice-president Sir Attenborough as he asks the world to help save the mountain gorilla. With your support, FFI & the International Gorilla Conservation Programme can protect this Critically Endangered species and help its population reach at least 1,001 individuals.

In return for your support we are also offering a selection of exclusive perks, including signed items by FFI vice-presidents Sir David Attenborough, Stephen Fry and Rove McManus.

Our Work Protecting Mountain Gorillas

The International Gorilla Conservation Programme (IGCP) is the coalition of conservation partners which FFI established with Sir David Attenborough in 1978 (then called the Mountain Gorilla Project).

The project fosters cooperation across national borders and empowers communities to monitor, protect and benefit from maintaining a healthy population of mountain gorillas.

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.

Tyrannosauridae: really interesting news

News tips:

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.

Scaring away sharks in AU using recorded sounds of orcas - a theory to be tested but there's concern that it could chase away other animals, upsetting the marine balance.

'Screams' could chase away other marine life
by: Mitchell Nadin

RECORDINGS of killer whale "screams" intended to scare sharks from popular West Australian beaches could end up chasing away other marine life, including dolphins.
