A giant sucking sound for sea turtles

04.08.2005


Study says Nicargua are last stop for endangered green turtles



Sea turtles that receive the highest protection in Costa Rica and other neighboring countries are dying by the thousands at the hands of unregulated - and unsustainable - commercial fishing in Nicaragua, according to a study by the Bronx Zoo based Wildlife Conservation Society.

The study, appearing in the latest issue of the journal Herpetologica, found that turtles tagged in Nicaragua have only little more than a 50 percent chance of surviving until the next year. This includes adult turtles from Tortuguero, a world famous turtle-nesting beach in Costa Rica. For a slow-growing, slow-to-mature species, removing so many large juveniles and adults from the population spells potential disaster, according to WCS scientists. The largest remaining green turtle population in the Atlantic lives in this region, scientists believe.


"Green turtles cannot take this relentless pounding by the Nicaraguan sea turtle fishing industry," said WCS researcher Cathi Campbell, the lead author of the study. "Drastic reductions are needed in fishing levels, or both the turtles - and turtle fishers - will vanish within a matter of years."

Although protected from international trade by CITES - the Convention on International Trade in Endangered Species, an estimated 11,000 green sea turtles are still harvested annually in Nicaragua for local consumption. WCS says that an annual quota of between 1,000-3,000 turtles needs to be established to sustain the fishery.

Green turtles - the only herbivorous sea turtle species - travel from throughout the Caribbean to Nicaragua to forage in its rich sea grass beds, making it especially frustrating for neighboring countries that protect turtles in their own waters, only to lose them once they enter Nicaragua, according to WCS.

"Other countries are doing so much to protect nesting populations and in-water aggregations of green turtles," Campbell said, noting that Costa Rica in particular has worked hard to protect nesting turtles from poachers. "Nicaragua plainly needs to do more to protect what is an international resource."

For the past seven years, WCS has worked along Nicaragua’s Miskito Coast to establish conservation programs that safeguard green, hawksbill and loggerhead turtles. WCS also operates turtle conservation programs in Africa.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
