Abstract Warming as well species introductions have increased over the past centuries, however a link between cause and effect of these two phenomena is still unclear. Here we use distribution records (1813–2023) to reconstruct invasion histories marine non‐native macrophytes, macroalgae seagrasses, in Mediterranean Sea. We defined expansion maximum linear rate spread (km year −1 ) accumulation occupied grid cells (50 km 2 time analyzed relation rates species' thermal conditions at its native range.

Abstract Temperate seaweed forests are among the most productive and widespread habitats in coastal waters. However, they under threat from climate change other anthropogenic stressors. To effectively conserve manage these ecosystems rising pressures, an understanding of genetic diversity structure habitat‐forming seaweeds will be necessary. Australia's Great Southern Reef, a global hotspot endemic diversity, is home to one world's speciose genera, Cystophora (order Fucales). Despite severe declines some species, genomic data on this genus remain limited. We used reduced representation approach (DaRTSeq) investigate racemosa , dominant canopy‐forming across ~850 km its range. Our sequencing captured 4741 high‐quality single nucleotide polymorphisms (SNPs), we distinguished neutral loci those natural selection (i.e., outlier loci). identified strong population high differentiation for both (mean F ST = 0.404) 0.901). Across populations, was low (neutral: mean H E 0.046; outlier: 0.042), with inferred inbreeding (neutral IS 0.531) no evidence isolation‐by‐distance. Several SNPs ( n 70) were observed putatively adaptive, (97%) correlated annual maximum sea surface temperature (SST, °C), indicating local adaptation key ocean variable. results show that C. populations have differentiation, which may increase vulnerability important foundation species change.
