Major turtle nesting beaches protected in 1 of the UK's far flung overseas territories

Major turtle nesting beaches protected in 1 of the UK's far flung overseas territories
2014-07-29
(Press-News.org) But on the remote UK overseas territory of Ascension Island, one of the world's largest green turtle populations is undergoing something of a renaissance.

Writing in the journal Biodiversity and Conservation, scientists from the University of Exeter and Ascension Island Government Conservation Department report that the number of green turtles nesting at the remote South Atlantic outpost has increased by more than 500 per cent since records began in the 1970s. As many as 24,000 nests are now estimated to be laid on the Island's main beaches every year, making it the second largest nesting colony for this species in the Atlantic Ocean.

Lead author, Dr Sam Weber, said: "The increase has been dramatic. Whereas in the 1970s and 80's you would have been lucky to find 30 turtles on the Island's main nesting beach on any night, in 2013 we had more than 400 females nesting in a single evening".

The scientists' report comes as Ascension Island Government announces that it is committing a fifth of the territory's land area to biodiversity conservation. New legislation enacted by the Island's Governor, Mark Capes, on the 28th of July creates seven new nature reserves and wildlife sanctuaries that include the Island's three main turtle nesting beaches, along with globally-important seabird colonies that are home to more than 800,000 nesting seabirds.

The legislation was developed during a two year project run by Ascension Island Government and the University of Exeter to develop a national biodiversity action plan for the territory.

Dr Nicola Weber, Ascension Island Government's Head of Conservation, said: "The decision to give legal protection to our most iconic wildlife sites follows extensive public consultation and has received a high level of support from across of the community. It speaks volumes as to how seriously environmental stewardship is currently taken on the Island".

Dr Annette Broderick, who is leading the project for the University of Exeter, added: "I am delighted that these globally important nesting sites have been afforded protection. This has been a goal for many years and has been achieved as a result of the dedication of the AI Government team who have been working towards this for several years."

To trace the origins of the current turtle boom you need to go back to before the Second World War. Dr Broderick, who has been researching sea turtles on Ascension Island for the past 15 years and led the recent study, said: "Green turtles were an important source of food for those on the island and passing ships would take live turtles onboard to ensure fresh meat for their voyage. Ships returning to the UK would stock up with turtles for the Lords of the Admiralty, who had a penchant for turtle soup. Records show a dramatic decline in the number of turtles harvested each year as fewer and fewer came to nest and since the 1950s no turtles have been harvested. We are now seeing the population bounce back, although our models suggest we have not yet reached pre-harvest levels."

Turtles were legally protected on Ascension Island in 1944 and the population has never looked back. "Because sea turtles take so long to reach breeding age, we are only now beginning to see the results of conservation measures introduced decades ago", says Dr Weber. "It just goes to show how populations of large, marine animals can recover from human exploitation if we protect them over long enough periods."

Could summer camp be the key to world peace?

2014-07-29
According to findings from a new study by University of Chicago Booth School of Business Professor Jane Risen, and Chicago Booth doctoral student Juliana Schroeder, it may at least be a start. Risen and Schroeder conducted research on Seeds of Peace, one of the largest peacebuilding programs that brings together teenagers from conflict regions, including Israelis and Palestinians, every year for three weeks in rural Maine. They tracked participants' feelings and attitudes toward the other national group for three years with three separate cohorts of campers. They found ...

Tough foam from tiny sheets

Tough foam from tiny sheets
2014-07-29
HOUSTON – (July 29, 2014) – Tough, ultralight foam of atom-thick sheets can be made to any size and shape through a chemical process invented at Rice University. In microscopic images, the foam dubbed "GO-0.5BN" looks like a nanoscale building, with floors and walls that reinforce each other. The structure consists of a pair of two-dimensional materials: floors and walls of graphene oxide that self-assemble with the assistance of hexagonal boron nitride platelets. The researchers say the foam could find use in structural components, as supercapacitor and battery electrodes ...

Research may explain how foremost anticancer guardian protein learned to switch sides
2014-07-29
Cold Spring Harbor, NY -- Researchers at Cold Spring Harbor Laboratory (CSHL) have discovered a new function of the body's most important tumor-suppressing protein. Called p53, this protein has been called "the guardian of the genome." It normally comes to the fore when healthy cells sense damage to their DNA caused by stress, such as exposure to toxic chemicals or intense exposure to the sun's UV rays. If the damage is severe, p53 can cause a cell to commit preprogrammed cell-death, or apoptosis. Mutant versions of p53 that no longer perform this vital function, on the ...

INDIANAPOLIS -- With the increasing use of electronic medical records and health information exchange, there is a growing demand for a computerized version of the preventive care guidelines pediatricians use across the United States. In a new study, researchers from the Indiana University School of Medicine and the Regenstrief Institute report that substantial work lies ahead to convert the American Academy of Pediatrics' Bright Future's guidelines into computerized prompts for physicians, but the payoff has the potential to significantly benefit patients from birth to ...

Menu secrets that can make you slim by design

2014-07-29
If you've ever ordered the wrong food at a restaurant, don't blame yourself; blame the menu. What you order may have less to do with what you want and more to do with a menu's layout and descriptions. After analyzing 217 menus and the selections of over 300 diners, the Cornell study published this month in the International Journal of Hospitality Management showed that when it comes to what you order for dinner, two things matter most: what you see on the menu and how you imagine it will taste. First, any food item that attracts attention (with bold, hightlighted or ...

From 'Finding Nemo' to minerals -- what riches lie in the deep sea?

From Finding Nemo to minerals -- what riches lie in the deep sea?
2014-07-29
As fishing and the harvesting of metals, gas and oil have expanded deeper and deeper into the ocean, scientists are drawing attention to the services provided by the deep sea, the world's largest environment. "This is the time to discuss deep-sea stewardship before exploitation is too much farther underway," says lead-author Andrew Thurber. In a review published today in Biogeosciences, a journal of the European Geosciences Union (EGU), Thurber and colleagues summarise what this habitat provides to humans, and emphasise the need to protect it. "The deep sea realm is so ...

Genomic analysis of prostate cancer indicates best course of action after surgery

2014-07-29
(PHILADELPHIA) – There is controversy over how best to treat patients after they've undergone surgery for prostate cancer. Does one wait until the cancer comes back or provide men with additional radiation therapy to prevent cancer recurrence? Now, a new study from Thomas Jefferson University shows that a genomic tool can help doctors and patients make a more informed decision. "We are moving away from treating everyone the same," says first author Robert Den, M.D., Assistant Professor of Radiation Oncology and Cancer Biology at Thomas Jefferson University. "Genomic ...

Optimum inertial self-propulsion design for snowman-like nanorobot

2014-07-29
Scale plays a major role in locomotion. Swimming microorganisms, such as bacteria and spermatozoa, are subjected to relatively small inertial forces compared to the viscous forces exerted by the surrounding fluid. Such low-level inertia makes self-propulsion a major challenge. Now, scientists have found that the direction of propulsion made possible by such inertia is opposite to that induced by a viscoelastic fluid. These findings have been published in EPJ E by François Nadal from the Alternative Energies and Atomic Energy Commission (CEA), in Le Barp, France, and colleagues. ...

NOAA: Alaska fisheries and communities at risk from ocean acidification
2014-07-29
Ocean acidification is driving changes in waters vital to Alaska's valuable commercial fisheries and subsistence way of life, according to new NOAA-led research that will be published online in Progress in Oceanography. Many of Alaska's nutritionally and economically valuable marine fisheries are located in waters that are already experiencing ocean acidification, and will see more in the near future, the study shows. Communities in southeast and southwest Alaska face the highest risk from ocean acidification because they rely heavily on fisheries that are expected to ...
