Distribution and ecology of Pelodytes caucasicus BOULENGER, 1896 in Turkey. The presently known distribution of Pelodytes caucasicus in Turkey comprises 14 localities within the eastern part of the coastal slopes of the Pontic mountain chain. The easternmost locality record (near Kars) needs confirmation. The species' vertical distribution ranges from near sea level to 1900 m a.s.l. Spawning sites of the Caucasian parsley frog are mostly densely overgrown, shallow parts of cool, slow moving brooks, rock pools within ravines, and residual pools in the gravel beds of rivers. All spawning sites were located in or very close to forested areas. The terrestrial habitats of adult specimens are unknown, but most probably are forests. Total lengths and masses of Turkish P. caucasicus correspond to literature data for Georgian and Caucasian populations. Average values of masses and total lengths of reproductive animals are slightly lower in the late breeding season compared to the early season. Data for the breeding season in Turkey range from July to October and usually larvae metamorphose in early summer of the following year. During the summer months larval populations of non flood-affected breeding sites consist of three size classes: freshly laid clutches plus hatchlings, half grown individuals, and metamorphosing animals. In contrast, breeding sites within small water bodies in mountain brooks often suffer from floods caused by runoff of melting snow or continous heavy summer rains. Those water bodies often contain only one size class of larvae during the summer, usually hatchlings or small tadpoles. Clutches of P. caucasicus contained 58-223 eggs. Satellite behaviour was observed several times at §enyuva. One calling male was accompanied by one to three non-calling males. In addition, the keeping of Pelodytes caucasiccus in an outdoor enclosure in northwestern Germany is reported.
