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: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
