The León rock lizard, Iberolacerta galani, lives in isolated mountains of Spain. We studied the seasonal changes in the thermal biology of I. galani between spring and summer. We calculated precision, accuracy and effectiveness of thermoregulation and the habitat thermal quality for spring, and compared with the values of summer. In addition, we studied how the shift in the thermal preferences ...

Theoretical and field studies suggest that inferior competitors may be able to avoid costly agonistic interactions, although the mechanisms involved are poorly understood in lizards. The “Dear enemy recognition” theory proposes that higher tolerance among familiar than among unfamiliar conspecifics may reduce costly interactions. Male lizards Lacerta monticola are able to discriminate between f...

This study was carried out to determine the fish fauna of Kuzgun Dam Lake dranaige. Eight (Barbus lacerta, Capoeta damascina, Alburnus sellal, Alburnoides velioglui, Squalius semae, Oxynoemacheilus araxensis, O. bergianus and Salmo euphrataeus) species belonging 4 families (Cyprinidae, Leuciscidae, Nemachelidae Salmonidae) were determined.

Thirty specimens of sand lizard, Lacerta agilis, were analyzed and Ophionyssus saurarum was found on three of them. These parasitic mites were located in the ear opening of the host. The only lizard specimens which were infested were those that inhabit areas degraded by human activity.
