Promiscuity in sand lizards (Lacerta agilis) and adder snakes (Vipera berus): causes and consequences.
We review postcopulatory phenomena in the Swedish sand lizard (Lacerta agilis) and adder (Vipera berus), and in particular, links between female promiscuity, determinants of paternity, and offspring viability. In both species, females mate multiply and exhibit a positive relationship between the number of partners and offspring viability. We conclude that this relationship is most likely the re...
متن کاملProximate determinants of telomere length in sand lizards (Lacerta agilis).
Telomeres are repeat sequences of non-coding DNA that cap the ends of chromosomes and contribute to their stability and the genomic integrity of cells. In evolutionary ecology, the main research target regarding these genomic structures has been their role in ageing and as a potential index of age. However, research on humans shows that a number of traits contribute to among-individual differen...
متن کاملContest success and mate guarding in male sand lizards, Lacerta agilis
Female sand lizards mate multiply with one or several males (Olsson 1992). After copulation the male stays temporarily with the mated female and vigorously attacks approaching males, whereafter he resumes mate search (Olsson 1992). Such agonistic behaviour by male lizards during the mating season is not novel (Carpenter 1977;Stamps 1983). However, in the majority of studies it has been investig...
متن کاملUV-Deprived Coloration Reduces Success in Mate Acquisition in Male Sand Lizards (Lacerta agilis)
BACKGROUND Recent work on animal signals has revealed a wide occurrence of UV signals in tetrapods, in particular birds, but also in lizards (and perhaps other Squamate reptiles). Our previous work on the Swedish sand lizard (Lacerta agilis) has verified, both in correlative selection analyses in the wild and with laboratory and field experiments, the importance of the green 'badge' on the body...
متن کاملHospital contacts after bite by the European adder (Vipera berus).
INTRODUCTION Bites by the European adder, Vipera berus, may cause significant morbidity in bite victims, but this can be reduced through adequate treatment. Since the previous Danish study, a new treatment and a severity grading has been taken into use. The aims of this study were to review clinical cases after a bite from V. berus in The North Denmark Region and to evaluate the treatment given...
