The degradation of the habitat represents a risk greater for the survival of the turtles that the increase of the temperature global. Is the conclusion of a new research carried out by the University of Bristol, the Museum of history Natural of London, both institutions of United Kingdom.
More than the 60 percent of them members of this group of animals are classified by the Union International for the conservation of the nature (IUCN) as vulnerable, in danger or in danger critical, because are being marketed and captured for the power and it medicine and their habitats is are degrading.
Team of researchers proposed to check if long-term climate change represents a threat or an opportunity for the turtles and how he might respond to an increase in global temperature.
Since the turtles live lives so long, is impossible carry to out experiments to test the impact of the warming during several generations.
The water, the key to their survival
Them turtles are very sensitive to the changes of temperature and precipitation, therefore, is concerned the impact of the change climate in its distribution. Along with overexploitation and habitat loss, climate change is a major threat to their conservation status with growth, abundance and geographic distribution that is expected to decrease under future projections of climate change.
In many species, temperature determines if the egg will become a male or a female, which shows a direct impact of global warming. As these animals live in ponds, rivers, land and sea, climate change may affect them through changes in temperature, precipitation, and ocean currents.
He Professor Paul Barrett, of the Museum of history Natural of London, adds: "others threats for the conservation, such the degradation of the habitat by the man and the barriers to the circulation, can be equal of important at the time of determine the destination of them turtles in a world in warming as the current".
