Estudio poblacional y genético de la tortuga Chelonia mydas agassizii (Sauria: Cheloniidae) en la Playa Chinchorro, Arica, Chile
Observations on Chelonia mydas agassizii have been carried out on a monthly basis for the last 2 years along the Chinchorro beach in Arica (northern Chile), with the aim of monitoring and describing genetic and population parameters in this group of turtles. Eighteen Ch. mydas agassizii individuals...

Eighteen Ch. mydas agassizii individuals were captured and marked from December 2011, to July 2013.
