Experimental Evolution in a Warming World: The Omics Era
Santos, Marta A.; Carromeu-Santos, Ana; Quina, Ana S; Antunes, Marta; Kristensen, Torsten N; Santos, Mauro; Matos, MargaridaA comprehensive understanding of the genetic mechanisms that shape species responses to thermal variation is essential for more accurate predictions of the impacts of climate change on biodiversity. Experimental evolution with high-throughput resequencing approaches (evolve and resequence) is a highly effective tool that has been increasingly employed to elucidate the genetic basis of adaptation. The number of ...
Experimental evolution in a warming world : the Omics era

Past history shapes evolution of reproductive success in a global warming scenario
Santos, Marta A.; Antunes, Marta; Grandela, Afonso; Carromeu-Santos, Ana; Quina, Ana S.; Santos, Mauro; Matos, Margarida; Simões, PedroAdaptive evolution is critical for animal populations to thrive in the fast-changing natural environments. Ectotherms are particularly vulnerable to global warming and, although their limited coping ability has been suggested, few real-time evolution experiments have directly accessed their evolutionary potential. Here, we report a long-term experimental evolution study addressing the evolution of Drosophila th...
Heat-induced female biased sex ratio during development is not mitigated after ...
Santos, Marta A.; Antunes, Marta; Grandela, Afonso; Carromeu-Santos, Ana; Quina, Ana; Santos, Mauro; Matos, Margarida; Simões, PedroBackground The negative impacts of climate change on biodiversity are consistently increasing. Developmen‑ tal stages are particularly sensitive in many ectotherms. Moreover, sex-specifc diferences in how organisms cope with thermal stress can produce biased sex ratios upon emergence, with potentially major impacts on population persistence. This is an issue that needs investigation, particularly testing whethe...
High developmental temperature leads to low reproduction despite adult temperature
Santos, Marta A.; Carromeu-Santos, Ana; Quina, Ana S.; Santos, Mauro; Matos, Margarida; Simões, PedroPhenotypic plasticity can help organisms cope with changing thermal conditions and it may depend on which life-stage the thermal stress is imposed: for instance, exposure to stressful temperatures during development can trigger a positive plastic response in adults. Here, we analyze the thermal plastic response of laboratory populations of Drosophila subobscura, derived from two contrasting latitudes of the Eur...
Beneficial developmental acclimation in reproductive performance under cold but...
Simões, Pedro; Santos, Marta A.; Carromeu-Santos, Ana; Quina, Ana S.; Santos, Mauro; Matos, MargaridaThermal plasticity can help organisms coping with climate change. In this study, we analyse how laboratory populations of the ectotherm species Drosophila subobscura, originally from two distinct latitudes and evolving for several generations in a stable thermal environment (18 °C), respond plastically to new thermal challenges. We measured adult performance (fecundity traits as a fitness proxy) of the experime...
