Abstract
Español
En las aguas de las islas Canarias (este del Atlántico) se pueden observar diferentes especies de tortugas marinas. Una de ellas es la tortuga verde (Chelonia mydas), menos frecuente que la tortuga boba (Caretta caretta), y de la que se dispone de muy poca información.
La ONG ADS Biodiversidad desarrolla actualmente un proyecto centrado en la tortuga verde y del que forma parte este programa de marcaje con transmisor. Dicho proyecto pretende determinar el origen de estos ejemplares, conocer su distribución en esta zona, qué tipo de hábitats están usando, y si están ligados o no a áreas con alguna figura de protección como, por ejemplo, la red Natura 2000. Además, se identificarán las principales presiones y amenazas a las que están expuestas estas tortugas.
Los resultados obtenidos se divulgarán entre la población local, siendo para muchos desconocida su presencia en estas aguas, incluso para algunos profesionales como pescadores y buceadores con los que interaccionan directamente.
*Título completo del proyecto: La tortuga verde (Chelonia mydas) y la red Natura 2000 en Canarias.
English
Several species of sea turtles can be observed in waters off the Canary Islands (Eastern Atlantic). One of them is the green turtle (Chelonia mydas), less frequent than the loggerhead sea turtle (Caretta caretta), and with little information.
The NGO ADS Biodiversidad is currently developing a project based on the green turtle and this satellite tracking programme forms part of it. The aims of this project are to determine the origin of these individuals, know their distribution in this area, determine the habitats that they are using and define if they are linked or not to protected areas (e.g. Natura 2000 network). Furthermore, the main pressures and threats that are affecting to this species will be determined.
Results of this project will be disclosed among the local population, that poorly know the presence of the species in Canarian waters, even for some professionals that interact directly with them (e.g. fishermen and divers).
Project title: The green turtle (Chelonia mydas) and the Natura 2000 network in the Canary Islands.
