Indian tigers need genetic diversity to survive

Royal Bengal Tiger India faces extinction.

Indian tigers face threat due to lack of genetic diversity. Tigers need genetic diversity to survive. India's tigers are facing extinction owing to a collapse in the variety of their mating partners, say Cardiff University researchers. They found that 93% of DNA variants found in tigers shot the period of the British Raj were not present in tigers today Prof Mike Bruford said the genetic diversity needed for the species to survive had been "lost dramatically". There are fewer than 2,000 tigers left worldwide, 60% in India. The Cardiff university team collaborated with the National Centre for Biological Sciences in Bangalore, India on the research. They had unprecedented access to the Natural History Museum of London's tiger collection which allowed them to identify the DNA variants in the tigers killed in the British Raj period from 1858 to 1947 but which have disappeared today. Mechanised trophy hunting reduced the animal's numbers from 40,000 in a mere 100 years. The territory occupied by the tiger has declined more than 50% during the last three generations and mating now only occurs in 7% of its historical territory.

He said: "We found that genetic diversity has been lost dramatically compared to the Raj tigers and what diversity remains has become much more subdivided into the small (20-120 individual) populations that exist today.

Wildlife Crime Threatens Species and Nations

Wildlife crime profound threat to nations, says report

The global illegal trade in wildlife

is worth $19bn (£12bn) a year and is threatening the stability of some

governments according to new research.

Carried out for conservation group WWF, a report highlights a "new wave" of

organised wildlife crime by armed groups operating across borders.

It says funds from trafficking are being used to finance civil conflicts.

The study comes as Malaysian officials captured about 20 tonnes of ivory in one of the

biggest seizures ever made.

 

“The bloody ivory trade has reached new heights of destruction and depravity in 2012”

According to Jim Leape, WWF International director

general, the report underlines the fact that wildlife crime has escalated

drastically over the past decade and now posed a greater threat than

ever.

10 Most Endangered Animals 2012

Picking a Ten Most Endangered Animals list was a tough job. For every critically endangered creature you select, you must leave out hundreds of other animals that are in just as much jeopardy.

That’s why we chose not to include the giant panda on our roster of the world’s ten most endangered animals. The panda, as appealing and important as it is, has gotten plenty of attention from conservationists and the public alike. Time to make room for another critically endangered animal or two that hasn’t had as much time in the spotlight of looming extinction.

Big Cat Species facing Extinction

Big Cat Species Facing Extinction 2010 was supposed to be the Year of the Tiger. Unfortunately, tigers, lynx, jaguars, leopards, lions, pumas, cheetahs, and every species of Big Cat in the world is in decline. How long these magnificent species can evade extinction is up to us. Big Cats are part of the Family Felidae (or feline), and are a rich addition to our natural world. However, the Big Cats are in severe decline throughout the planet. The Anthropocene Extinction, also known as the Holocene Extinction event, is the world’s 6th great sudden loss of life. We are currently in the third wave of this, and man-made ecological effects such as an overexploitation of species, pollution, the introduction of alien species, and habitat encroachment are directly responsible for the decline and extinction of thousands of species of life.

Crime chiefs agree to get tough on illegal tiger trade

Crime chiefs from countries with populations of wild tigers have agreed to work together in order to combat the illegal trade in the big cats.

Heads of police and customs from 13 nations agreed to tighten controls and improve cross-border co-operation at a two-day meeting in Bangkok.

Only six subspecies remain, with fewer than 1,000 tigers in each group.

Smuggling of tiger parts is one of the main threats facing the planet's remaining big cats, say experts.

Indian Village Moved to Save Endangered Tigers

India village in Rajasthan relocates to protect tigers

India's tiger numbers have shrunk from 100,000 to 1,700 in a little over a century
 

An entire village has been relocated in the northern Indian state of Rajasthan to protect tigers, officials say.

More than 350 people from 82 families in Umri village, in the Sariska tiger reserve, moved to a new location.

The number of tigers in Sariska had dwindled to zero before growing to five over the last three years.

Tiger numbers have shrunk alarmingly in India in recent decades. A 2011 census counted about 1,700 tigers in the wild.

A century ago there were estimated to be 100,000 tigers in India.

Compensation

Umri is the second village in Sariska to be relocated to help secure a proper habitat for tigers to increase their numbers. The villagers moved last week.

There are 11 villages with a population of nearly 2,500 people located in the heart of the tiger reserve which need to be relocated to improve the habitat, Rajasthan's chief conservator of forests, PS Somasekhar, told the BBC.

People living in these villages mostly belong to pastoral tribes.

Mr Somasekhar said efforts were being made to relocate four more villages over the next few years.
