“…obs). Altogether, our results along with previous evidence support the idea that a dual increase in heat constraints and water restriction during summer, and their impact on activity patterns, is a potential driver of local extinction in natural populations of the common lizard (Chamaillé-Jammes, Massot, Aragon, & Clobert, 2006;Rutschmann, Miles, Clobert, & Richard, 2016).…”

“…Temperature conditions were highly variable during the study, ranging from cool summer days to heat wave conditions (Figure 1a; Figure S1). This is similar to observations made in natural populations (Rutschmann et al, 2016). Our study design therefore successfully allowed for the comparison of the behaviour of the same lizards in two different water conditions and under variable thermal constraints.…”

Mechanistic models of terrestrial ectotherms predict that climate warming will induce activity restriction due to heat stress and loss of shade, leading to the extinction of numerous populations. Such models rely on the assumption that activity patterns are dictated by simple temperature thresholds independent of changes in water availability. However, changes in water availability may further influence thermoregulation behaviour of ectotherms through dehydration risk perception, changes in water balance or changes in microclimatic conditions. Here, we experimentally assess the interactive effects of thermal conditions and water availability on activity patterns, shade selection and thermoregulation efficiency in a model ectothermic species. Thermoregulation behaviour of adult common lizards Zootoca vivipara was monitored in outdoor mesocosms as we manipulated water availability, providing water as mist in the morning and free‐standing water during the daytime. We recorded operative temperatures and micro‐meteorological conditions to infer thermal constraints and dehydration risk. Activity and shade selection were better predicted by continuous changes in thermal conditions and dehydration risk, respectively, than by threshold functions. In addition, water supplementation increased activity in males and reduced shade selection in both sexes, most probably as a behavioural response to the perception of a stronger dehydration risk. Water supplementation also influenced the thermal quality of the environment, which in turn altered daily activity patterns and thermoregulation statistics. This demonstrates that dual effects of heat and water stress on activity patterns may lead to stronger activity restriction as a result of climate change than currently predicted.

“…delayed timing of parturition in populations with higher forest cover had also been demonstrated in a smaller sample of our study sites (Rutschmann et al 2016a). In the common lizard, advancement of gestation is associated with a shift toward lower thermal preferences, which is more obvious at the end of pregnancy (ca.…”

Behavioral thermoregulation is an efficient mechanism to buffer the physiological effects of climate change. Thermal ecology studies have traditionally tested how thermal constraints shape thermoregulatory behaviors without accounting for the potential major effects of landscape structure and water availability. Thus, we lack a general understanding of the multifactorial determinants of thermoregulatory behaviors in natural populations. In this study, we quantified the relative contribution of elevation, thermal gradient, moisture gradient and landscape structure in

“…Second, unlike some insects that can adjust the relationship between egg size and number on the basis of food quality [ 66 , 67 ], female T. septentrionalis likely allocate optimal energy to a clutch of eggs and developing offspring, resulting in relatively fixed egg and clutch sizes that are resistant to environmental perturbations such as thermal heterogeneity and food availability [ 19 , 58 , 68 ]. Nonetheless, a substantial increase in environmental temperatures may increase clutch frequency in T. septentrionalis [ 19 ] or clutch size in some other species [ 21 , 41 , 69 ]. Third, the low immune capability (Fig.…”

Parental effects may produce adaptive or maladaptive plasticity that either facilitates persistence or increases the extinction risk of species and populations in a changing climate. However, empirical evidence of transgenerational adaptive plastic responses to climate change is still scarce. Here we conducted thermal manipulation experiments with a factorial design in a Chinese lacertid lizard (Takydromus septentrionalis) to identify the fitness consequences of parental effects in response to climate warming. Compared to present climate conditions, a simulated warming climate significantly advanced the timing of oviposition, depressed the immune capability of post-partum females, and decreased the hatching success of embryos, but did not affect female reproductive output (clutch size and egg mass). These results indicate that maternal warming negatively affects female health, and embryonic hatchability. More interestingly, we found that offspring from parents exposed to warming environments survived well under a simulated warming climate, but not under a present climate scenario. Accordingly, our study demonstrates anticipatory parental effects in response to a warming climate in an ectothermic vertebrate. However, the fitness consequences of this parental effect will depend on future climate change scenarios.Electronic supplementary materialThe online version of this article (10.1186/s12983-018-0296-3) contains supplementary material, which is available to authorized users.
