Data on population size, adult sex ratio, body size and mass are provided for a population of the turtle Emys orbicularis near Pazaragaç (Afyonkarahisar/Turkey). Using the mark-recapture method (triple catch), a population size of 664 turtles was estimated (95% confidence interval, range 332-996), corresponding to a density of 83 turtles per hectare (range 41.5-124.5). The adult sex-ratio was significantly skewed in favor of males (2.02 males: 1 female; P < 0.001). Almost all recorded specimens were adult (98.1%). Mean straight carapace length (SCL) and body mass (BM) of adult turtles were: SCL = 128.65 mm, BM = 345 g for males (n = 168) and SCL = 135.37 mm, BM = 463 g for females (n = 83). © 2007 Institute of Zoology, Slovak Academy of Sciences., This study constitutes part of a project [Project No: TBAG-2402 (103T189)] supported by TÜBİTAK (The Scientific and Technical Research Council of Turkey). We are indebted to TÜBİTAK for financial support.
