In the present study, we contributed to knowledge of distribution endemic lizard species, Pamphylian green in Turkey and pointed out northernmost localities species. Until recently, occurrence species was only known from Antalya Mersin provinces Turkey. According most recent records, it has been reported some (Aşağı Kırıntı, Yukarı Kasımlar, Belence) Sütçüler district Isparta province. our also...

The mechanisms underlying honest signal expression remain elusive and may involve the integration of social and physiological costs. Corticosterone is a socially modulated metabolic hormone that mediates energy investment and behavior and may therefore function to deter dishonest signal expression. We examined the relationship between corticosterone and green badge coloration in male sand lizar...

OBJECTIVE This study was conducted to determine the prevalence of Ligula intestinalis and infections caused by these on freshwater fish in rivers and streams in the Kars plateau of north-eastern Anatolia, Turkey. METHODS This research was conducted between April and July 2011. Fish samples were caught via a casting net and an electro-shocker. The samples were immediately examined to determine...

Novel selective pressures derived from human activities challenge the persistence of animal populations worldwide. Behavior is expected to be a major factor driving animals' responses to global change because it largely determines how animals interact with the environment. However, the role of individual variation in behavior to facilitate the persistence of animals in changing environments rem...

Phenotypic similarity of species occupying similar habitats has long been taken as strong evidence of adaptation, but this approach implicitly assumes that similarity is evolutionarily derived. However, even derived similarities may not represent convergent adaptation if the similarities did not evolve as a result of the same selection pressures; an alternative possibility is that the similar f...

The desert-dwelling sandfish (Scincus scincus) moves within dry sand, a material that displays solid and fluidlike behavior. High-speed x-ray imaging shows that below the surface, the lizard no longer uses limbs for propulsion but generates thrust to overcome drag by propagating an undulatory traveling wave down the body. Although viscous hydrodynamics can predict swimming speed in fluids such ...
