Abstract Species with widespread distributions play a crucial role in our understanding of climate change impacts on population structure. In marine species, structure is often governed by both high connectivity potential and selection across strong environmental gradients. Despite the complexity factors influencing populations, studying species broad distribution can provide valuable insights into relative importance these consequences climate‐induced alterations We used northern shrimp Pandalus borealis its wide latitudinal to identify current drivers predict species' vulnerability change. A total 1514 individuals sampled 24° latitude were genotyped at geographic (54 stations) genetic (14,331 SNPs) resolutions assess variation correlations. Four populations identified addition finer substructure associated local adaptation. Geographic patterns neutral reflected predominant oceanographic currents, while significant proportion was gradients salinity temperature. Adaptive landscapes generated using projections suggest larger genomic offset southern extent P. range, where had largest adaptive standing variation. Our results combined recent observations point further deterioration regions an impending vulnerable status higher latitudes for . They also rare climatic meroplanktonic which future challenges invertebrates essential ecosystem functioning.
