(05/14/2013) In March, two people were caught attempting to smuggle 54 ploughshare tortoises (Astrochelys yniphora) into Thailand. Listed as Critically Endangered, the tortoises' wild population is down to approximately 400-500 animals in its native Madagascar, meaning the smugglers were attempting to move over 10 percent of the total population. Now, the Scientific American blog Extinction Countdown reports that nearly half of the smuggled tortoises have died of unknown causes.
Scientists discover that marine animals disperse seagrass
(05/09/2013) Lesser known than coral reefs, marine seagrass ecosystems are rich in biodiversity and are powerhouses when it comes to sequestering carbon dioxide. Yet, much remains unknown about the ecology of seagrass beds, including detailed information on how seagrass spread their seeds and colonize new area. Now a recent study in Marine Ecology Progress Series documents that several species of marine animal are key to dispersing seagrass, overturning the assumption that seagrass was largely dispersed by abiotic methods (such as wind and waves).
How many animals do we need to keep extinction at bay?
(04/15/2013) How many animal individuals are needed to ensure a species isn't doomed to extinction even with our best conservation efforts? While no one knows exactly, scientists have created complex models to attempt an answer. They call this important threshold the "minimum viable population" and have spilled plenty of ink trying to decipher estimates, many of which fall in the thousands. However, a new study in Conservation Biology shows that some long-lived animals may not need so many individuals to retain a stable population.
Over ten percent of a species' total population found in smuggler's bag
(03/25/2013) On Friday, March 15th Thai authorities arrested a 38-year-old man attempting to collect a bag containing 54 ploughshare tortoises (Astrochelys yniphora) and 21 radiated tortoises (Astrochelys radiata) in Suvarnabhumi International Airport. Found only in Madagascar both species are listed as Critically Endangered and protected under the Convention on International Trade in Endangered Species (CITES), but have become lucrative targets for the black-market pet trade given their scarcity and beauty.
Turtles win greater protection at CITES meeting
(03/08/2013) Dozens of freshwater turtle and tortoise species won greater protection under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), reports the U.S. Fish and Wildlife Service.
Leatherback sea turtles suffer 78 percent decline at critical nesting sites in Pacific
(02/27/2013) The world's largest sea turtle, the leatherback (Dermochelys coriacea), is vanishing from its most important nesting sites in the western Pacific, according to a new study in Ecosphere. Scientists found that leatherback turtle nests have dropped by 78 percent in less than 30 years in the Bird's Head Peninsula on the island of New Guinea. Worryingly, these beaches account for three-fourths of the western Pacific's distinct leatherback population; globally the leatherback is listed as Critically Endangered by the IUCN Red List, the highest rating before extinction.
Endangered turtle urinates through its mouth
(10/11/2012) One of China's most commonly farmed turtles for consumption, the Chinese soft-shelled turtle (Pelodiscus sinensis), has a unique ability: it urinates out of its mouth. Researchers in Singapore, writing in The Journal of Experimental Biology, have discovered that the Chinese soft-shelled turtle excretes most of its urine from its mouth instead of its kidneys. They hypothesize that the turtle developed this ability in order to survive in brackish waters, which contain considerably more salt than freshwater.
Turtle knowledge in Africa shows significant gaps
(09/17/2012) Sometimes turtles fall through the cracks: a new study in the open access journal Tropical Conservation Science, has uncovered a number of 'gap species' in the turtle families inhabiting Africa. 'Gap species' are those that are recorded in one country or another, but not in adjacent countries which could be due to a lack of data, a change in ecosystems, or human impacts.
Lonesome George passes, taking unique subspecies with him
(06/25/2012) Lonesome George, the sole surviving member of the Pinta Island tortoise (Chelonoidis nigra abingdoni), was found dead on Sunday by staff at the Galapagos National Park. With George's passing, the Pinta Island tortoise subspecies officially falls into extinction. First found in 1972, Lonesome George became famous for representing the last of his kind. He was believed to be around 100—middle-aged for a Galapagos tortoise which can live to 200 years old. Staff plan to do an autopsy to determine the cause of death.
Conservationists successfully hatch world's fourth most endangered turtle
(06/11/2012) The world's fourth most endangered turtle has received a happy boost from breeding efforts, reports the AFP. Bangladeshi scientists have successfully hatched 25 northern river terrapins (Batagur baska) using an artificial beach constructed in the country's Bhawal National Park.
Hail Mary effort aims to save the world's most endangered turtles
(04/17/2012) The Wildlife Conservation Society (WCS) has pledged to work with all of its institutions to save at least half of the world's most 25 endangered turtles as listed in a report by WCS and the Turtle Conservation Coalition last year. The program will include both conservation work in the field as well as participation from WCS's zoological institutions for captive breeding and future reintroductions. Even with WCS's ambitious program, however, it is likely this century will see a number of turtle extinctions.
Featured video: the world's greatest turtle collection
(04/16/2012) At a seemingly small residence in Florida, lives the world's greatest turtle collection. The Chelonian Research Institute contains a specimen of nearly every species of turtle found worldwide and many live species. Founded and headed by Dr. Peter Pritchard, the institute is both a research center and an active museum.
Picture of the day: nearly-extinct turtle released into the wild in Cambodia
(01/18/2012) Only around 200 southern river terrapins (Batagur affinis) survive in the wild, but today at least the species got some good news. A female terrapin was released back into the Sre Ambel River with much fanfare after being caught by a local fishermen in Cambodia.
