More details on the tiger species.
Tiger Conservation is an Issue
When conservation issues are discussed, it's usually the tiger that gets the most attention. This is not helping the conservation of most sub-species, as aspects of its criminal poaching cause further decline.
Tiger, tiger, burning less bright
The Indian tiger is the largest population remaining today. It is in deep trouble, like many others, because genetic isolation is taking place. One ray of hope is some increase in variation, but this could be a fault due to sampling.
Does de-extinction stink?
Whether mammoth or tiger sub-species, mouse or marsupial, there are many arguments for 'de-extinction, or 'bringing back' species that have slipped through the net of conservationists.

Are Conservation Groups Right to Prioritize 'Iconic' Species?
Conservationists are often accused of prioritizing 'cute and cuddly' animals over les glamorous species. For their part, some conservationists argue that harnessing the potential of 'flagship species' such as gorillas, tigers and pandas does far more good than harm. Tackling this issue for 'The Earth Times Asks' series of debates are Helen Buckland and Nathan Yaussy.

'Kings of the hill' vital for sculpting healthy ecosystems
The 'apex consumers' of the living world - the lions and tigers and bears, not to mention whales - play an often overlooked role in shaping the ecosystem they sit at the top of. A new review in Science out today, from 24 ecologists, points to the dramatic effects that the weakening of those at the top of the food chain can have - and calls for a new approach that values the conservation of the 'kings of the hill'.

Critically Endangered species given boost by new study
Species with low populations can still be saved. These species, such as the Siberian tiger and mountain gorilla, were thought by some scientists to be 'too rare to save'. Some of the world's most endangered species exist in populations far smaller than previous studies had argued were necessary for survival.
WWF releases rare footage of Sumatran tigers
Two Sumatran tiger families caught on camera. Camera traps captured images and footage of 12 Sumatran tigers, including two females with cubs, in the Bukit Tigapuluh forests.

Forearms point to Tasmanian tiger as a solitary hunter
The Tasmanian tiger, or thylacine, really was more like a solitary stalking tiger than a wolf, says a study into the bones of this extinct marsupial in the latest Biology Letters. That means it wasn't a direct competitor with the introduced dingo - raising questions about exactly how this top predator met its untimely demise in mainland Australia.
Tigers to return to Central Asia

Worrying news for critically endangered Siberian tigers
The critically endangered Siberian tiger has an effective population of just 14 animals - that's the worrying conclusion of a recent study into these stunning cats. The Siberian tiger, also known as the Amur tiger, is the world's largest cat. Previously it ranged far across northern China, Korea and south eastern Russia. In the early 20th Century the Siberian tiger was driven close to extinction through poaching and habitat loss and was wiped out from 90% of its once large range.

Concerted efforts to develop joined up tiger reserves could triple tiger numbers in Asia.

An international team of scientists led by Dr Eric Dinerstein of chief scientist at WWF in the United States set out to discover whether this was even possible.
