Anthropogenic impact or anthropogenic accommodation? Distribution range expansion of the common wall lizard (Podarcis muralis) by means of artificial habitats in the north-eastern limits of its distribution range
During 2005-2008, field observations were made on the distribution and habitat occupation by Podarcis muralis in the middle Bistrita river basin. Prior to our study, this lizard was known from only 5 localities in Romanian Moldavia (Bicaz, Cheile Bicazului, Lacu Roşu, Gherman and Dodeni). Through the present paper the authors acknowledge the existence of 28 sites populated by P. muralis in Mold...
متن کاملSeasonal variations of plasma testosterone among colour-morph common wall lizards (Podarcis muralis).
Sexual steroids influence reproductive behaviours and promote secondary sexual traits. In male lizards, increasing levels of testosterone (T) bolster conspicuous colouration, stimulate territoriality, and trigger antagonistic interactions among rivals. Moreover, in colour polymorphic species, reproductive strategy, aggressiveness and T levels can differ between morphs. Therefore, T level is con...
متن کاملThe impact of land use intensity and associated pesticide applications on fitness and enzymatic activity in reptiles-A field study.
Environmental pollution and habitat loss are described as underlying causes for population declines in reptiles and especially affect species in agricultural landscapes. Studies dealing with effects of pesticide exposure on reptiles are limited, mainly addressing the orders Testudines and Crocodylia, but largely neglecting the most diverse reptile order Squamata (lizards and snakes). As a conse...
متن کاملSexual selection drives asymmetric introgression in wall lizards.
Hybridisation is increasingly recognised as an important cause of diversification and adaptation. Here, we show how divergence in male secondary sexual characters between two lineages of the common wall lizard (Podarcis muralis) gives rise to strong asymmetries in male competitive ability and mating success, resulting in asymmetric hybridisation upon secondary contact. Combined with no negative...
متن کاملDermal photoreceptors regulate basking behavior in the lizard Podarcis muralis.
There is evidence that dermal photic responsiveness can be found in a wide range of animals. Behavioral responses to dermal stimulation by light have been observed in pigeon squabs and new-born rats, and more recently in a sea snake. Here we report that painting the dorsal surface of the lizard (Podarcis muralis) with opaque black paint impairs the animal's ability to position itself beneath a ...
