The present work describes the presence of a digenean in the red-eared turtle Trachemys scripta elegans (Wied-Neuwied, 1839) in marshes of the Valencian Community. The faeces and intestinal tract of 105 animals were examined. Only one helminth species was found and identified as the digenean trematode Telorchis atenuatta (Goldberger, 1911), present in the 7.6% of the animals analysed. This is the first report of the parasite in sliders from Spain. Although conclusions are preliminary due to the limited sampling, our results suggest that the presence of red-eared turtles in new habitats may increase the risk of introducing new microorganisms and new diseases with them, altering the sanitary status of the autochthonous terrapins Mauremys leprosa (Schweigger, 1812) and Emys orbicularis (Linnaeus, 1758).

Sun basking is the most common method for freshwater turtles, such as the European pond turtle, to maintain optimal body temperature. The attributes of the macro- and microhabitat features around the basking sites affect the basking site selection of the European pond turtle. To protect the European pond turtle, it is important to know the basking habits among the biological characteristics of the species, along with the effects of the habitat characteristics and the choice of the type of basking sites. The purpose of our research was to detect the effects of macro- and microhabitat features on the selection of basking sites. We wanted to determine basking site type selection according to the carapace length classes and if there is any difference in the choice of basking trunks and branches with different thicknesses. Turtles choose basking sites with less closed vegetation in their environment. We have detected seasonal differences in the microhabitat features. The closing reed and Typha sp. had a negative effect on the number of observed basking turtles. The most popular type of basking sites in the pond system was the commonly occurred fallen tree trunks and branches in the water, regardless of turtle body size. Most turtles used thinner tree trunks and branches for basking. In the meantime, we found differences in the choice of basking trunks between the turtles with different body sizes. Younger turtles with smaller bodies appeared in larger numbers on emergent branches with smaller diameters.

Experimental study on the early stages of development of the front limbs of the embryo of the chelonian Emys orbicularis L.: mosaic determination and regulation Ablation of postotic somites 6–13 on one side in embryos of Emys orbicularis L. or injury to the adjacent somatopleure at the developmental stage when 15–21 somite pairs were present, led to arrest of forelimb-bud development in this part of the somatopleure on the operated side. Limb development in the remaining part of prospective somatopleure on the operated side was investigated 5–11 days after the operation. When this part of somatopleure was adjacent to cranial somites 6–9 or 6–10, the development stopped at the start of the apical crest as in Anguis or Scelotes forelimb-buds. A part of somatopleure adjacent to caudal somites 8–12, 9–12 or 10–12 developed into a normal limb with three segments; a part of somatopleure adjacent to 1–2 somites only, developed into a reduced limb, scarcely swelling. Each somitic level developed in relation to its initial regional determination dependent on position in the cephalocaudal axis; to its environment (cranial or caudal bud) and to the quantity of somatopleural material in the bud.
