The Leatherback Strikes Back
In Puerto Rico, near one of the leatherback turtles nesting areas in the southern Caribbean and northern South America, the conservation battle has raged long and often.
Surfing by tortoises
Genetic surfing in tortoises. It's created among a population that is subject to many founding events and lots of genetic drift!
The Terrible Turtle Trade in Indonesia
The illegal trade in endangered freshwater turtles. The pig nosed turtle is unique, its facial features add to its desirability for 'so-called' enthusiasts.
Sea Turtles Dig the Dark
Artificial lighting kills thousands of sea turtles every year, it disorients newborn sea turtle hatchlings, which are trying to find their way to the sea. The The Sea Turtle Conservancy has highlighted this environmental issue and is implementing a program to educate people and address the problem.

Lost Years of Leatherback Sea Turtle Hatchlings
Come back, Leatherback! When leatherback sea turtle hatchlings take off from their nests they enter the 'Lost Years' (from 0-10 years old). This period is important to us now that declining populations have forced us to adopt any conservation means at our disposal.
Loggerhead sea turtle habitat locations discovered in the Gulf of Mexico
Two new feeding 'hotspots' of the endangered loggerhead sea turtle (Caretta caretta) have been discovered by scientists using satellite tags to track their movements in the Gulf of Mexico.
Endangered green turtle migration mapped
Cruising the eastern Pacific is everyone's dream, but the green turtle, the only herbivore among the sea turtles, seems to have it made in one sense. The invaluable Gorgona National Park, not far from Galapagos, was used for the sampling of green turtles migration by snorkelling at night around the eastern reefs.
Khaki Army to protest against dugong and sea turtle killing
A protest organised by Earthrace Conservation UK will take place in London later this week against the killing of dugongs and sea turtles in Australia.

DNA tests suggest the giant Floreana tortoise, which has been thought to be extinct for 150 years, may be alive on Wolf Volcano in the Galapagos Islands.
Sharks and marine turtles in trouble around the world
New research indicates that sharks and marine turtles are in trouble around the globe. Scientists offer some new insights into possible methods for reversing these trends. Pressures on marine environments - from rising sea temperatures and overfishing to pollution and oils spills - is taking an increasingly heavy toll on a variety of marine species including turtles and sharks.
Some loggerhead turtle populations downgraded to endangered status
Loggerhead turtle populations across the globe have been divided into nine distinct populations, with more than half downgraded from threatened to endangered status under the United States Endangered Species Act.
Holidaymakers can help conserve leatherback turtles
Keep your eyes peeled for the leatherback turtle this month in the UK, says the Marine Conservation Council - and let them know about your sightings. These monstrous paddlers are most common in the UK's waters at this time of year, as they follow the jellyfish swarms northwards.
DNA tests unravel a tricky tortoise mystery
Just how many species of desert tortoises are there? For 150 years since the species' discovery, it was believed that the desert tortoise is one species. However, evidence has been mounting that desert tortoises should in fact be two separate species.
Celebrating Turtles: World Turtle Day 2011
Celebrating turtles! Sponsored by American Tortoise Rescue since 2000, World Turtle Day 2011 aims to increase our knowledge of, and respect for, turtles and tortoises. It also aims to encourage human actions to help turtles and tortoises survive and thrive.
Africa's sea turtles need extra protection
Existing protected areas are inadequate in safeguarding turtles from fishing nets, a new study has found. This is the first comprehensive tracking study of olive ridley turtles during the nesting season, using satellite transmitters to follow 18 female turtles.
China and U.S. announce fisheries and climate change deals
The world's two largest economies have announced cooperation on fisheries and greenhouse gases. They hope to stop unregulated fish stocks from going on sale, monitor the management of threatened species and to reduce the toll of protected marine animals like sea turtles.
WSC wades in to stop US bog turtle decline
Bog turtles, tiny fen-dwelling reptiles found at scattered sites in the north-east and eastern US, are being hit by a mysterious decline in numbers. Now the Wildlife Conservation Society (WSC) has partnered with other wildlife agencies to track the scope of the problem, and try and find out why North America's smallest turtle is coming under renewed threat.
Ile aux Aigrettes rewilding experiment reports success
Researchers at the University of Bristol's School of Biological Sciences report that after ten years, introduced tortoises served as ''effective seed dispersers'' for regrowing an endangered tree species in Mauritius' Ile aux Aigrettes nature reserve. Beginning in 2000, 18 adult and sub adult Giant Aldabran Tortoises were brought to the island of Ile aux Aigrettes in an effort to save and regrow the island's endangered ebony forest
Loggerhead turtles 'on the move' pick up more pollution
In a first for conservationists seeking to help the beleaguered loggerhead sea turtle, scientists making use of satellite transmitters have been able to accurately track how the turtle's movements expose them to a range of man-made chemicals. And it seems that those turtles that are Floridan stay-at-homes fare better than those ranging along the eastern US seaboard.
Marine life under threat because of our dependence on plastic
Plastic is flooding the world's oceans, damaging sea-life. The stomach contents of a young sea-turtle found dead off the Argentinian coast were examined by scientists. It was found to contain hundreds of small pieces of plastic detritus. More than half of the 90 sea-turtles found dead of the coast of Brazil were found with similar shards of plastic in their guts or faeces.
Loggerhead turtle migration mystery solved
Geomagnetic cues help young loggerhead turtles navigate the open ocean during their epic 8,000 mile journey between leaving their natal beaches in Florida, and returning 5-10 years later to breed. Researchers have just worked out how they do it. The loggerhead's secret is to use both the angle, or inclination; and the strength of the earth's magnetic field to deliver enough information to determine its exact position on the planet both east-west and north-south.
Danger signals for the future of turtles
Human intervention is causing a serious decline in the world turtle population. 2011 has been designated 'The Year of the Turtle' by Partners in Amphibian and Reptile Conservation (PARC). Turtles are currently disappearing from the planet faster than any other kind of animal and although they have been around for about 220 million years.
2011: The Year of the Turtle, for conservationists at least
Conservationists around the world have pledged to make 2001 the Year of the Turtle and bring some of the world's oldest species back from the brink of extinction. While for the Chinese 2011 is the Year of the Rabbit, for an international group of conservationists it is the Year of the Turtle. For, after some 220 million years of being on the planet, around half of all species are now under threat from a range of man-made problems
Scientists track leatherback turtle travels for the first time
Satellite tracking technology has helped British scientists map the route taken by female leatherhead turtles for the first time. The marked decline seen in global populations of leatherback turtles can be partly attributed to the fact that their annual migratory routes force the animals to run the gauntlet of long-line fishing boats in the middle of the Atlantic Ocean.
Save sharks and sea turtles but not bluefin tuna says fishing industry
A recent international meeting in Paris has agreed to increase global protection for sharks and sea turtles; but the bluefin tuna appears to have lost out. Representatives from 48 nations recently met to discuss the fate of fishing quotas in the Atlantic and Mediterranean seas.
