Marine Protected Areas are keeping turtles safe

19.03.2012
Marine Protected Areas (MPAs) are providing sea turtles with an ideal habitat for foraging and may be keeping them safe from the threats of fishing.

A study by an international team of scientists led by the University of Exeter, published today (Thursday 15 March), shows that 35 per cent of the world's green turtles are found within MPAs. This is much higher that would be expected as only a small proportion of shallow oceans are designated as MPAs.

MPAs are areas of ocean in which marine activities such as fishing are restricted. Regulated by governments and NGOs, in the tropics they are often rich in seagrass and algae, providing food for the turtles, whose foraging may also help to maintain these habitats. There are different categories of MPAs, with the most strictly-protected being managed mainly for science.

The research team used data on the movements of 145 green turtles from 28 nesting sites, captured through extensive satellite tracking work by a collaborative team from ten countries. Their data shows that green turtles can travel thousands of miles from their breeding sites to their feeding ding grounds. 35 per cent of these were found to be foraging in MPAs. 21 per cent were found in MPAs that are most strictly protected and older MPAs were more likely to contain turtles.

Professor Brendan Godley of the University of Exeter's Centre for Ecology and Conservation said: "Our global overview revealed that sea turtles appear in Marine Protected Areas far more than would be expected by chance. There has been debate over the value of MPAs, but this research provides compelling evidence that they may be effective in providing safe foraging habitats for large marine creatures, such as green turtles.

"The satellite tracking work that the University of Exeter has played such a lead role in developing allows us to assess the value of MPAs in a way that would never have previously been possible."

This study is published in the journal Global Ecology and Biogeography. It was facilitated by SEATURTLE.org and the group is funded by NERC and Defra's Darwin Initiative. .

Fisheries Minister Richard Benyon welcomed the results of the research: "This study unlocks some of the secrets surrounding the life cycle of marine turtles, whose movements have long been a mystery. The results will mean we will better manage the oceans and protect turtle habitats which are key to helping them survive.

"This also shows the vital collaborative role Defra's Darwin Initiative plays in the cutting edge of conservation worldwide."

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...
