Understanding the genetic basis of local adaptation in thermal performance is useful for predicting species distribution shifts under anthropogenic climate change. Many are distributed across multiple biogeographic regions, and uniquely adapted populations each region may respond to future ocean warming with distinct changes. In present study, we investigated phylogeographic patterns, sensitivity, differentiation intertidal snail Littorina brevicula along China's coast. Whole-genome sequencing results based on a newly assembled chromosome-level genome revealed two lineages, north-south divergence that linked environment. Within lineage, individuals could be further subdivided into subgroups differ at key genomic loci underpinning differences upper heat tolerance. Heat stress drives adaptive levels organization, from individual level. Taking account diversity associated variation tolerance, physiological model (pSDM) was applied predict distributions different response Both northern southern lineages were predicted experience declines habitat suitability 4°C scenario, genotypic subset snails lineage even driven extinction. These findings illustrate when species' range maintained, it can nonetheless significant decrease as result The integrated approach presented here, which considered both level within biogeographical context, provided new insights how marine global warming.

Microhabitat environmental factors (e.g., temperature, oxygen concentration, nutrients, osmotic stress, and topography) are critical to the survival of intertidal organisms. Understanding how transcription responses regulated in relation microhabitat variation has important implications for studying adaptive evolution these The barnacle Chthamalus challengeri, which survives zone is subjected periodic tidal changes, serves as an ideal species detecting In this study, we designed a series situ conditions C. challengeri sequenced their transcriptome collected from various microhabitats. We aimed detect genetic adaptation mechanisms barnacles responding changes based on comparative transcriptomics. Our results indicated that different microhabitats significantly affected gene expression models particularly genes related physiological biochemical functions. Specifically, such CYP450, HSP70, CYTB, COX1 was increased under low tide (air-exposed conditions), while like CNGA3, AK, CP52 showed high (seawater-immersed conditions). suggest relies cytochrome p450 enzymes enhance oxidative capacity, counts heat shock proteins cell phagocytosis resist response conditions, produces hypoxic stress regulate energy metabolism body temperature upon entering into seawater. This study provides resources clues investigating identifies
