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: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
