| Abstract |
|
Between 2009 and 2012 an assessment of the population of European pond turtle (Emys orbicularis) inhabiting the sinkholes that are part of the lagoons in the Natural Monument of Cañada del Hoyo has been made. The population has been monitored using capture-mark-recapture (CMR techniques), being captured almost 80 turtles. The analysis of CMR data in the program MARK indicates that a population of 60 individuals is estimated based on the survival rates detected. The proportion of sexes is biased towards males (2:1), the percentage of adults is 45% of the total population. Recruitment appears to be high, since the population has about 55% of juveniles and immatures.
