Evolutionary adaptation under climate change: sp. demonstrates potential to adapt to warming.

Climate warming is expected to shift the distributions of mosquitoes and mosquito-borne diseases, promoting expansions at cool range edges and contractions at warm range edges. However, whether mosquito populations could maintain their warm edges through evolutionary adaptation remains unknown. Here, we investigate the potential for thermal adaptation in , a congener of the major disease vector species that experiences large thermal gradients in its native range, by assaying tolerance to prolonged and acute heat exposure, and its genetic basis in a diverse, field-derived population.

Dominance reversal protects large-effect resistance polymorphisms in temporally varying environments.

A central challenge in evolutionary biology is to uncover mechanisms maintaining functional genetic variation in heterogeneous environments . Population genetics theory suggests that beneficial reversal of dominance, where alleles are dominant when beneficial and recessive when deleterious, can help maintain such variation in temporally varying environments . However, empirical examples are scarce due to difficulties in measuring dominance in fitness in field experiments .

pigmentation demonstrates adaptive phenotypic parallelism but genomic unpredictability over multiple timescales.

Unlabelled: Populations are capable of responding to environmental change over ecological timescales via adaptive tracking. However, the translation from patterns of allele frequency change to rapid adaptation of complex traits remains unresolved. We used abdominal pigmentation in as a model phenotype to address the nature, genetic architecture, and repeatability of rapid adaptation in the field.

Molecular basis of ocean acidification sensitivity and adaptation in .

Predicting the potential for species adaption to climate change is challenged by the need to identify the physiological mechanisms that underpin species vulnerability. Here, we investigated the sensitivity to ocean acidification in marine mussels during early development, and specifically the trochophore stage. Using RNA and DNA sequencing and RNA hybridization, we identified developmental processes associated with abnormal development and rapid adaptation to low pH.

Magnitude and Predictability of pH Fluctuations Shape Plastic Responses to Ocean Acidification.

AbstractPhenotypic plasticity is expected to facilitate the persistence of natural populations as global change progresses. The attributes of fluctuating environments that favor the evolution of plasticity have received extensive theoretical investigation, yet empirical validation of these findings is still in its infancy. Here, we combine high-resolution environmental data with a laboratory-based experiment to explore the influence of habitat pH fluctuation dynamics on the plasticity of gene expression in two populations of the Mediterranean mussel, .
