1. Contemporary climate change affects population dynamics, but its influence varies with landscape structure. It is still unclear whether landscape fragmentation buffers or enhances the effects of climate on population size and on the age and body size of individuals composing these populations. 2. This study aims to investigate the impacts of warm climates on lizard life-history traits and population dynamics in habitats varying in their connectivity. 3. We monitored common lizard (Zootoca vivipara) populations...
