Spur-thighed Tortoise (Testudo graeca<\/em>)<\/span> \u00a9A. Olivier<\/figcaption><\/figure>\n

Abstract<\/b>:<\/p>\n

The Spur-thighed tortoise (Testudo graeca<\/i>) is listed as vulnerable on the IUCN Red List, with small and fragmented populations located around the Mediterranean basin. In Turkey, this species has remained poorly studied which hampers solid assessment of threats and conservation measures. We studied the spatial distribution, habitat use, and demography of the species in the Gediz Delta (Aegean coast of Turkey) between 2015 and 2017 with a specific capture-mark-recapture survey made in the Sazl\u0131g\u00f6l marshes. A total of 114 individuals (20 juveniles, 62 males and 32 females) were captured and released in that period. Carapace length of adult females was on average higher (205.2\u00b13.2 mm) than in adult males (190.9\u00b12.3 mm). Sex ratio was biased with 1.94 males per female. Based on the capture-recapture histories of 65 individuals (3 juveniles, 37 males and 25 females) marked in 2015, we estimated the population size of the Sazl\u0131g\u00f6l marsh population to be 137\u00b123 individuals, which corresponds to a density of 5.7 individuals per ha. The main threats detected were agricultural activities, urbanisation and captures for the pet trade.<\/p>\n
