Faced with climate warming, ectothermic species shift their breeding phenology, which is in part attributed to an acceleration of gestation or incubation in warmer environments. Thermal acceleration of gestation may have important fitness implications for breeding females and their offspring by impacting maternal homeostasis, embryonic development and hatching date, but these benefits and costs have been poorly documented. In addition, while climate change is characterised by a stronger trend for night-time than for daytime warming and concurrent alterations of food availability, few studies have quantified phenology-trait effects of increasing nocturnal temperatures and decreasing food intake. Here, we exposed female common lizards (Zootoca vivipara) to contrasted nocturnal temperatures and prey availability during gestation. We investigated multiple traits to quantify the functional impacts of nocturnal warming and food availability on breeding phenology, maternal condition, physiology and behaviour, current reproductive output and both females and offspring life-history traits.
