New study has identified two major foraging grounds of the Mediterranean green turtle and recommends the creation of a new Marine Protected Area
A new study led by the University of Exeter has identified two major foraging grounds of the Mediterranean green turtle and recommends the creation of a new Marine Protected Area (MPA) to preserve the vulnerable species.
The researchers tracked green turtles from breeding grounds in Cyprus, Turkey, Israel and Syria to provide the most comprehensive set of distribution data ever assembled for the species in the Mediterranean.
The study, published today in the journal Diversity and Distributions, identifies ten foraging grounds, with two major hotspots in Libya accounting for more than half of the turtles which were tracked to conclusive endpoints.
Professor Brendan Godley of the Centre for Ecology and Conservation at the University of Exeter, the paper's senior author, said: "We know where the major nesting grounds are but a robust understanding of where marine turtles go during migration and foraging phases is crucial to the development of effective conservation strategies. Of the two key habitats identified in this study - the Gulf of Bomba and the Gulf of Sirte - only the former is currently recognised as a biodiversity hotspot. The protection of both would benefit a high proportion of the adult green turtle population in the Mediterranean."
The species has suffered extreme declines in the past due to heavy overharvesting under British administration during the 20th century for meat and turtle soup. Additionally, within the region, the magnitude of marine turtle bycatch - the unwanted fish and marine creatures trapped by commercial fishing - is considered unsustainable by many conservationists who call for urgent action.
In this latest study, 34 female green turtles were satellite tracked from breeding grounds for a total of 8,521 tracking days between 1998 and 2010.
Dr Kim Stokes, lead author, added: "Although this study has led to a quantum leap in our knowledge of the species in the Mediterranean, there is clearly an urgent need to extend the tracking to some of the other major nesting beaches in Eastern Turkey and Cyprus to ensure we fully map the major migratory corridors and foraging grounds."

About the University of Exeter
The University of Exeter is a Russell Group university and in the top one percent of institutions globally. It combines world-class research with very high levels of student satisfaction. Exeter has over 18,000 students and is ranked 8th in The Times and The Sunday Times Good University Guide league table, 10th in The Complete University Guide and 12th in the Guardian University Guide 2014. In the 2008 Research Assessment Exercise (RAE) 90% of the University's research was rated as being at internationally recognised levels and 16 of its 31 subjects are ranked in the top 10, with 27 subjects ranked in the top 20. Exeter was The Sunday Times University of the Year 2012-13. The University has four campuses. The Streatham and St Luke's campuses are in Exeter and there are two campuses in Cornwall, Penryn and Truro. In a pioneering arrangement in the UK, the Penryn Campus is jointly owned and managed with Falmouth University. At the campus, University of Exeter students can study programmes in the following areas: Animal Behaviour, Conservation Biology and Ecology, English, Environmental Science, Evolutionary Biology, Geography, Geology, History, Human Sciences, Mathematics and the Environment, Mining and Minerals Engineering, Politics and International Relations, Renewable Energy and Zoology. The University has invested strategically to deliver more than £350 million worth of new facilities across its campuses in the past few years; including landmark new student services centres - the Forum in Exeter and The Exchange at Penryn - together with world-class new facilities for Biosciences, the Business School and the Environment and Sustainability Institute. There are plans for another £330 million of investment between now and 2016.

The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
