Governments should act now to save threatened turtles

01.11.2006
Ecology and conservation experts from the University of Exeter today urge international governments to work together to protect threatened Caribbean sea turtle populations.

The Cayman Islands, a UK Overseas Territory, once supported one of the world’s largest sea turtle rookeries, which comprised some 6.5 million adult green and loggerhead turtles. These populations were driven into decline from the mid-1600s onwards, when massive harvesting of nesting turtles began. Only a few dozen individuals survive today.

New research, led by the University of Exeter’s School of Biosciences and the Cayman Islands Department of Environment, reveals the astonishing distances these animals travel and the extent to which they are now threatened. The study was published open access today in the international conservation journal Endangered Species Research.

Marine turtles spend most of their lives at sea, but where these Cayman Islands survivors live when they are not nesting has been a mystery until now. Experts from the University of Exeter, the Cayman Islands Department of Environment and Duke University, USA, followed the journeys of ten endangered adult females over three years.

Using satellite transmitters, the team tracked the turtles travelling as far as Belize, Guatemala, Honduras, Mexico, Nicaragua and the USA. On these long journeys, turtles face the risk of being caught for meat, as well as accidentally captured by shrimp trawls, longlines, and gillnets. As turtles travel across boundaries between countries, conservation legislation is inconsistently applied and enforced, leaving them vulnerable.

Dr Brendan Godley of the School of Biosciences at the University of Exeter said: ‘Having followed these turtles thousands of miles through the ocean, we now know where they go, so can identify which countries need to be involved in their conservation. We are running out of time and what is now needed is a team effort from all of the governments to save these fragile populations.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
