The hard-shell mussel (Mytilus coruscus) is widespread in the temperate coastal areas of northwest Pacific and holds a significant position shellfish aquaculture market China. However, natural resources this species have been declining, population genetic studies M. coruscus are also lacking. In study, we conducted whole-genome resequencing (WGR) from eight different latitudes along Chinese coast identified total 25,859,986 single nucleotide polymorphism (SNP) markers. Our findings indicated that diversity Zhoushan region was lower compared with populations other regions. Furthermore, observed evolutionary tree clustered into two primary branches, Zhangzhou (ZZ) separate branch. ZZ partly isolated regions, but distribution branches not geographically homogeneous, nested pattern emerged, consistent differentiation index (FST) results. To investigate selection characteristics, utilized northern (Dalian Qingdao) central (Zhoushan Xiangshan) as reference southern target population. scan analysis several genes associated thermal responses, including Hsp70 CYP450. These may play important roles adaptation to living environments. Overall, our study provides comprehensive understanding genomic China valuable resource for future on breeding species.

We observed significant association between outlier SNPs, temperature, precipitation. Thermal adaptations evident, lower survival rates at high temperatures warm‐origin compensated by higher reproduction rates. Cold‐origin snails, hand, exhibited growth adapted shorter growing season. Ecophysiological included elevated sugar hemoglobin contents cold‐adapted snails. contrast, warm‐adapted displayed not only increased protein levels but also more oxidative damage. Furthermore, heightened phenoloxidase indicated robust immune response parasite‐rich regions. These morphological physiological differences provide convincing evidence genetic basis adaptation.

Abstract Intertidal organisms usually live near their upper thermal limits, and are vulnerable to future global warming. As a vital response stress, thermoregulatory strategy in physiological behavioral performance is essential for coping with stress surviving the changing world. To investigate relationship between habitat temperature, present study, we comparatively investigated responsive among different geographic populations of supralittoral snail Littoraria sinensis by determining snails’ cardiac function performance. Our results indicated that inhabiting high ambient temperatures had higher sublethal (i.e. Arrhenius breakpoint temperatures, ABTs, temperature at which heart rate shapely decreases further heating) lethal Flatline FLTs, ceases), behaved less actively (e.g. shorter moving distances time) face rising temperatures—a fight strategy. On other hand, relatively low lower limits ABTs FLTs moved more flight These demonstrate strategies snails closely related divergent environments.

Thermal performance curves (TPCs) provide a powerful framework to assess the evolution of thermal sensitivity in populations exposed divergent selection regimes across latitude. However, there is lack consensus regarding extent which physiological adjustments that compensate for latitudinal temperature variation (metabolic cold adaptation; MCA) may alter shape TPCs, including potential repercussion on upper limits. To address this, we compared TPCs cardiac activity latitudinally-separated intertidal periwinkle Littorina saxatilis. We applied non-linear TPC modelling approach explore how different metrics governing varied systematically response local adaptation and acclimation. Both critical limits, temperatures at was maximised, were higher northernmost (cold-adapted) population displayed countergradient trend most pronounced following acclimation low temperatures. interpret this as knock-on consequence increased standard metabolic rate high latitude populations, indicating compensation associated with MCA indirectly influence limits Our study highlights danger assuming any one aspect adaptive without appropriate mechanistic ecological context.
