Abstract The expected changes in pace-of-life with climate warming should impact the individual variation in behaviour (aka personality traits) within populations with consequences on eco-evolutionary dynamics. Yet, the effect of climatic conditions on personality traits is rarely studied over entire lifetimes, making its association with the pace-of-life difficult to investigate. Here, using a dataset spanning 10 years of a semi-natural warming experiment carried out on the common lizard Zootoca vivipara, we studied the effect of age on 3 personality traits (activity, exploration, sociability). We further investigated climate impacts on activity level, a trait particularly embedded within a pace-of-life syndrome with more active individuals living at a faster pace. We hypothesized that warmer climates would accelerate the ageing of activity compared to present-day climates, with consequences on all fitness components. Beyond being repeatable through the lifetime, activity and exploration showed similar ageing patterns, with adults being more active and exploratory than juveniles but becoming less so as they aged as a result of both selective disappearance and plastic changes. Sociability was less repeatable, and showed weaker ageing patterns. In a present-day climate, higher activity was linked to a faster pace of life with improved growth, survival and reproduction rates in early life and a reduced life expectancy. A warmer climate mitigated this activity-related pace-of-life, with individuals reaching similar performances regardless of their activity level. This led to an overall lower intraspecific variation in activity in warmer climates potentially reducing the resilience to warmer climates and other environmental changes. Hence such a pace-of-life alteration likely have consequences for their population dynamics and persistence and, given the link of activity with metabolism, energy expenditure and foraging, likely influences consumptive and non-consumptive interactions with species at lower trophic levels and so ecological networks as a whole. 1.4.
