turtleThe Turtle is an ancient species, represented in the fossil record as far back as 200 million years ago. There are approximately 270 species in the world occupying all continents except Antarctica. Of these, approximately half are in need of some form of conservation action because they are threatened with extinction. The threats to turtles are habitat destruction, pollution, disease, and overexploitation by an increasingly hungry world. In the face of this onslaught, turtles face a more insidious threat: predicted global increases in temperature caused by greenhouse gases.

Even if turtles survive the possible effects of global climate change, they will still have to contend with other predicted changes. As cold-blooded animals, digestion rate, growth, reproduction and activity are all closely related to temperature. In addition, changing water levels in lakes, rivers and wetlands, could have major impacts on access to suitable nest sites and habitat. Their conservative evolutionary history suggests that they will not be able to adapt to rapid changes. Turtles may have outlived the dinosaurs, but it remains to be seen if turtles can survive in the modern world.

This Week in Sea Turtles

TWiST 9: Go Green, Slow Down, Have a Good Time - Hosts: Michael Coyne and Manjula Tiwari Don't listen to what we say, this is actually TWiST #9. We talk to J Nichols, president of the International Sea Turtle Society, about the upcoming sea turtle symposium in Loreto, Baja California Sur, Mexico.
TWiST 8: Morocco & Gabon - Hosts: Michael Coyne, Matthew Godfrey and Manjula Tiwari Manjula regales us with tales from recent trips to Morocco and Gabon and brings us up to date on sea turtle activities in those countries. Show notes and links at Topics: Morocco field visits (nesting, strandings, bycatch) Mauritania Cape Verde Canary Islands Gabon TEDs workshop NMFS training and technology transfer Testing TEDs
TWiST 7: Proceedings - Hosts: Michael Coyne, Matthew Godfrey and Manjula Tiwari Don't be confused. We recorded two episodes at once. Episodes 6 and 7 were recorded back to back and I just split the file. In the second half (episode 7) we discuss the recent kerfuffle surrounding the Annual Sea Turtle Symposium proceedings initiated by Peter Pritchard's editorial in MTN 115. And a funny rebuke of Stephen Colbert and the Colbert Report from The Motley Fool.
