“…Rather, they may serve as an integrated phenotypic readout of temperature adaptation. Nevertheless, there are other laboratory studies conforming to the expectations from natural populations (Cavicchi et al., 1995; Huey et al., 1991; Stazione et al., 2020). This inconclusive behaviour could be explained by the correlated response of high‐level phenotypes with the adaptive phenotypes which may or may not be broken in different laboratory experiments.…”

Ecological adaptation is frequently inferred by the comparison of natural populations from different environments. Nevertheless, inference of the selective forces suffers the challenge that many environmental factors covary. With well‐controlled environmental conditions, experimental evolution provides a powerful approach to complement the analysis of natural populations. On the other hand, it is apparent that laboratory conditions differ in many ways from natural environments, which raises the question as to what extent selection responses in experimental evolution studies can inform us about adaptation processes in the wild. In this study, we compared the expression profiles of replicated Drosophila melanogaster populations which have been exposed to two distinct temperature regimes (18/28 and 10/20°C) in the laboratory for more than 80 generations. Using gene‐wise differential expression analysis and co‐expression network analysis, we identified 541 genes and three coregulated gene modules that evolved in the same direction in both temperature regimes, and most of these changes probably reflect an adaptation to the space constraint or diurnal temperature fluctuation that is common in both selection regimes. In total, 203 genes and seven modules evolved temperature‐specific expression changes. Remarkably, we detected a significant overlap of these temperature‐adaptive genes/modules from experimental evolution with temperature‐adaptive genes inferred from natural Drosophila populations covering two different temperature clines. We conclude that well‐designed experimental evolution studies are a powerful tool to dissect evolutionary responses.

“…Then, cross-tolerance studies can provide valuable information about the evolutionary response to multiple environmental stressors. Cross-tolerance evolution has been reported among different resistance traits [29,35,47,48], but the magnitude of the evolutionary response could be explained by the trait under direct selection or the stress intensity [38]. Here, an artificial selection experiment was performed on knockdown temperature to explore whether the intensity of thermal selection influences the cross-tolerance evolution of resistance traits in D. subobscura .…”

Cross-tolerance evolution has been reported among different resistance traits (Hoffmann and Parsons 1993; Bubliy and Loeschcke 2005; Stazione et al 2020; Singh et al 2022), but the magnitude of the evolutionary response could be explained by the trait under direct selection or the stress intensity (Gerken et al 2016). Here, artificial selection for heat tolerance (i.e., knockdown temperature) resulted in correlated responses in heat knockdown time, the thermal tolerance landscape (TDT curves), desiccation resistance, and starvation resistance.…”

Evolution of heat tolerance is a crucial mechanism for the adaptive response to global warming, but it depends on the genetic variance harbored by populations and the thermal stress intensity in nature. Selection experiments on heat tolerance have been key to understand the heat tolerance evolution but the effect of variable heat stress intensity on the correlated responses of resistance traits has not been explored. Here, the effects of heat intensity selection (fast and slow ramping temperatures) for increasing knockdown temperature in Drosophila subobscura were evaluated on the knockdown time at different stressful temperatures (35, 36, 37, and 38 °C), the thermal-death-time curves (TDT curves), the desiccation and starvation resistance. Correlated evolution was found for these four resistance traits in D. subobscura, which demonstrates that the evolutionary response to tolerate higher temperatures also confers the capacity to tolerate other stress such as desiccation and starvation. However, these correlated responses depended on the intensity of thermal selection and sex, which could limit our capacities to transfer these findings to natural scenarios. Nevertheless, this study reaffirms the value of experimental evolutionary approach to explore and to understand the adaptive responses of natural populations to global warming.

“…We measured two well‐established proxies of cold‐ and heat stress resistance in insects, namely ‘chill‐coma recovery time’ (CCRT) and ‘heat knock‐down time’ (HKDT) (e.g. Bauerfeind & Fischer, 2014; Fischer et al, 2010; Stazione et al, 2020; Tonione et al, 2020). All individuals were tested for CCRT on day 2 of adult life and for HKDT the day after.…”

Elucidating the factors that shape species ranges is of central concern in both evolutionary biology and ecology (Hardie & Hutchings, 2010;Polechová, 2017). Recently, many taxa have been reported to shift or expand their ranges in response to anthropogenic climate change (Chen et al., 2011;Pinsky et al., 2020). This is especially true for many insect taxa, including butterflies, as their ectothermic nature makes them highly sensitive to changes in temperature (Breed
