abstract = {* Substantial plastic variation in phenology in response to environmental heterogeneity through time in the same population has been uncovered in many species. However, our understanding of differences in reaction norms of phenology among populations from a given species remains limited. * As the plasticity of phenological traits is often influenced by local thermal conditions, we expect local temperature to generate variation in the reaction norms between populations. * Here, we explored temporal variation in parturition date across 11 populations of the common lizard (Zootoca vivipara) from four mountain chains as a function of air temperatures during mid-gestation. We characterized among-population variation to assess how local weather conditions (mean and variance of ambient temperatures during mid-gestation) and habitat openness (an index of anthropogenic disturbance) influence the thermal reaction norms of the parturition date. * Our results provide evidence of interactive effects of anthropogenic disturbance and thermal conditions, with earlier parturition dates in warmer years on average especially in closed habitats. * Variation in the reaction norms for parturition date was correlated with mean local thermal conditions at a broad geographical scale. However, populations exposed to variable thermal conditions had flatter thermal reaction norms. * Assessing whether environmental heterogeneity drives differentiation among reaction norms is crucial to estimate the capacity of different populations to contend with projected climatic and anthropogenic challenges.},

abstract = {The consequences of within-cohort (i.e., among-individual) variation for population dynamics are poorly understood, in particular for the case where life history is density dependent. We develop a physiologically structured population model that incorporates individual variation among and within cohorts and allows us to explore the intertwined relationship between individual life history and population dynamics. Our model is parameterized for the lizard Zootoca vivipara and reproduces well the species' dynamics and life history. We explore two common mechanisms that generate within-cohort variation: variability in food intake and variability in birth date. Predicted population dynamics are inherently very stable and do not qualitatively change when either of these sources of individual variation is introduced. However, increased within-cohort variation in food intake leads to changes in morphology, with longer but skinnier individuals, even though mean food intake does not change. Morphological changes result from a seemingly universal nonlinear relationship between growth and resource availability but may become apparent only in environments with strongly fluctuating resources. Overall, our results highlight the importance of using a mechanistic framework to gain insights into how different sources of intraspecific variability translate into life-history and population-dynamic changes.},

abstract = {An evaluation of the link between climate and population dynamics requires 

understanding of climate effects both within and across generations. In ectothermic 

vertebrates, demographic responses to climate changes should crucially depend on balancing 

needs for heat and water. Here, we studied how temperature and rainfall regimes experienced 

before and during adulthood influenced reproductive performances (litter size, offspring size, 

and survival) in a natural population of the live-bearing common lizard, Lacerta vivipara, 

monitored continuously from 1989 to 2004. Rainfall regime, but not temperature, had both 

immediate and delayed effects on these reproductive performances. Rainfall during the first 

month of life was positively correlated with juvenile survival. Females experiencing more 

rainfall during gestation produced smaller neonates that showed greater survival when 

controlling for the positive effect of body size on survival. Furthermore, females that 

experienced heavier rainfall when in utero produced fewer but longer neonates during 

adulthood. These demographic effects of rainfall on adult reproductive traits may come from 

maternal effects of climate conditions andtextbackslashor from delayed effects of rainfall on the 

environment experienced early in life. Irrespective of the precise mechanism, however, this 

study provides evidence of intergenerational climate effects in natural populations of an 

ectothermic vertebrate.},
