Environment-dependence of behavioural consistency in adult male European green lizards (Lacerta viridis)
Understanding the background mechanisms affecting the emergence and maintenance of consistent between-individual variation within population in single (animal personality) or across multiple (behavioural syndrome) behaviours has key importance. State-dependence theory suggests that behaviour is 'anchored' to individual state (e.g. body condition, gender, age) and behavioural consistency emerges...
متن کاملUltraviolet nuptial colour determines fight success in male European green lizards (Lacerta viridis).
Animal communication through colour signals is a central theme in sexual selection. Structural colours can be just as costly and honest signals as pigment-based colours. Ultraviolet (UV) is a structural colour that can be important both in intrasexual competition and mate choice. However, it is still unknown if a UV signal alone can determine the outcome of male-male fights. European green liza...
متن کاملBorrelia lusitaniae and Green Lizards (Lacerta viridis), Karst Region, Slovakia
In Europe, spirochetes within the Borrelia burgdorferi sensu lato complex are transmitted by Ixodes ricinus ticks. Specific associations are described between reservoir hosts and individual genospecies. We focused on green lizard (Lacerta viridis) as a host for ticks and potential host for borreliae. In 2004 and 2005, a total of 146 green lizards infested by ticks were captured, and 469 I. rici...
متن کاملExpression of breeding coloration in European Green Lizards (Lacerta viridis): variation with morphology and tick infestation
According to the hypothesis of parasite-mediated sexual selection, for a communication system to work reliably, parasites should reduce the showiness of sexual signals of their host. In this study, we examined whether the expression of breeding coloration in free-ranging adult European Green Lizards (Lacerta viridis (Laurenti, 1768)) is linked with infestation by their common ectoparasite Ixode...
متن کاملLipophilic compounds from the femoral gland secretions of male Hungarian green lizards, Lacerta viridis.
In spite of the importance of chemical signals (pheromones) in the reproductive behaviour of lizards, only a few studies have examined the role of specific chemical compounds as sexual signals. The secreted chemicals vary widely between species but whether this variation reflects phylogenetic or environmental differences remains unclear. Based on mass spectra, obtained by GC-MS, we found 40 lip...
