Scientist warns of threat to last stronghold of endangered turtle

09.03.2006


A major conservation effort, led by Dr Brendan Godley of the University of Exeter, has just got underway to help protect endangered leatherback turtles which nest in Gabon, West Africa. The region is thought to be the animals’ last global stronghold, as pacific populations dwindle precariously.



It’s hoped the project, to tag and track the animals, will uncover their migratory secrets and provide the basis for efforts to safeguard them. After fitting them with satellite trackers the team are using the internet to follow their journeys, which are among the longest in the animal kingdom.

Dr Brendan Godley, of the University of Exeter, said: "Pacific leatherbacks have been decimated by incidental capture at sea and overexploitation so it’s vital that we protect the Atlantic population.


This project is crucial to our understanding of the geographical range of the leatherback as so little is currently known about their travels. We think turtles from Gabon could be traveling as far afield as South America, Europe and even the Indian Ocean to feed on their jellyfish prey.

Once we have detailed information our tracking work will feed directly into strategies for marine protected areas in Gabon and farther afield and more sustainable fisheries.

We are just beginning to understand the importance of the leatherbacks of West Africa as a global stronghold but we need to know where they live to protect them."

The tracking data is publicly available online and is creating much interest with more than 100,000 hits from over 150 countries on the site www.seaturtle.org/tracking each month.

It’s thought that globally more than 50,000 leatherback turtles are incidentally caught by fisherman trawling for other species each year. Of these, thousands are thought to die as a result. Approximately 1.4 billion hooks are cast into the world’s oceans as part of industrial long-line fishing, with 37% of this fishing effort in the Atlantic. A major hotspot is found off West Africa, the focus of this study.

With fishing yields decreasing in European seas the EU has struck up a number of agreements with African nations to fish their waters. Amazingly, most EU fishing concessions don’t even incorporate compulsory bycatch monitoring programmes.

Scientists from the University of Exeter’s Cornwall Campus are working with a consortium of partners in Gabon (Aventures Sans Frontieres, Parcs Gabon and Wildlife Conservation Society) and the USA (Duke University, SEATURTLE.org) to try to solve the mystery of where the turtles’ spend their time.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
