Major turtle nesting beaches protected in one of the UK’s far flung overseas territories

Sea turtles are not a species one would normally associate with the United Kingdom. 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.

Legal harvest of marine turtles tops 42,000 each year

A new study has found that 42 countries or territories around the world permit the harvest of marine turtles – and estimates that more than 42,000 turtles are caught each year by these fisheries.

The research, carried out by Blue Ventures Conservation and staff at the University of Exeter’s Centre for Ecology and Conservation, is the first to comprehensively review the number of turtles currently taken within the law and assess how this compares to other global threats to the creatures.

Turtles’ Mating Habits Protect Against Effects of Climate Change

The mating habits of marine turtle may help protect them against the effects of climate change, according to new research led by the University.

Published on 25th January 2012 in Proceedings of the Royal Society B, the study shows how mating patterns of a population of endangered green turtles may be helping them deal with the fact that global warming is leading to a disproportionate number of females being born.

The gender of baby turtles is determined by the temperature of the eggs during incubation, with warmer temperatures leading to more females being born. Higher average global temperatures mean that offspring from some populations are predominantly female. This is threatening the future of some populations and there are concerns that inbreeding within groups due to a lack of males will lead to health problems. (more…)
