| contents | <p><span>1. Shifting breeding phenology is a widespread response to global warming in ectothermic species such as reptiles. In turn, breeding phenology can have considerable impacts on reproductive success and population dynamics. Thus, understanding causes and consequences of plasticity and micro-evolution in breeding phenology is important for determining vulnerability to climate change.</span></p> <p><span>2. Here, we study environmental and individual determinants of breeding phenology, its heritability and the temporal variation of selection on parturition date using a 31-year monitoring of a wild population of common lizards (<em>Zootoca vivipara</em>).</span></p> <p><span>3. Mean daily maximum temperatures during the post-winter activity period and body size drove variation in parturition dates. On average, warmer temperatures advanced parturition dates and larger females gave birth earlier, but warmer temperatures also reduced size-related phenological variability.</span></p> <p><span>4. Over 31 years, breeding phenology did not change towards earlier or later dates despite an increase of +0.6 °C per decade in mean daily maximum temperatures at our study site. Parturition dates were repeatable among females but weakly heritable, which suggests that inter-individual consistency of parturition dates may be related to non-heritable factors such as home range quality, nutritional condition or behaviour. In addition, we found evidence for a directional selection toward earlier parturition, without fluctuation in time.</span></p> <p><span>5. This study highlights the strong interannual thermal plasticity coupled with a limited adaptive potential of breeding phenology in the common lizard. In future, warmer conditions, the interplay between such plasticity and a selection apparently independent from environmental fluctuations would thus essentially depend on the, yet unknown, costs of thermal plasticity.</span></p> |
