Detached buoyant kelp can disperse thousands of kilometres at sea and colonize newly available shores in the wake disturbances that wipe out competitors. Localized earthquake uplift cause extirpation intertidal populations followed by recolonization. Sources recolonizing be detectable genomic structure contemporary populations. Our field observations combined with LiDAR mapping identified a previously unrecognized zone uplifted rocky coastline region is slowly subsiding. Intertidal ( Durvillaea antarctica ) on section coast genetically distinctive from nearby populations, signatures most similar to 300 km south. Genetic divergence between these locations suggests reproductive isolation for years. Combined geological genetic data suggest this event occurred during one four major earthquakes 6000 2000 years ago, younger events likely. Extirpation pre-existing required sudden approximately 2 metres, precluding several small incremental events. results show power integrating biological (genomic) analyses understand ancient processes their ecological impacts.

Historical vicariance events, linked to the existence of stable physical barriers gene flow, generate concordant genetic breaks in co-distributed species while stochastic processes (e.g., costal uplift) could cause species-specific as a result local strong demographic bottlenecks or extinction. In Chile, previous studies show that area 30°S-33°S correspond barrier flow have affected structure various algae and marine invertebrates. Here we sequenced two organellar genes (COI rbcL) four taxonomically accepted red seaweeds characterized by low dispersal potential: Mazzaella laminarioides, M. membranacea, Asterfilopsis disciplinalis, Ahnfeltiopsis vermicularis . Our results revealed ten strongly differentiated linages taxa studied. Strong breaks, both space time (divergence estimated occurred some 2.9–12.4 million years ago), were observed between distributed across 33°S. Conversely, Central/South part Chilean coast, localization breaks/sub-structure varied widely (36°S, 38°S, 39°S, 40°S). These suggest major historical event has modeled several organisms north coast during mid-Miocene, more recent events drift be driving forces divergence/structuration central-southern coast.

Large‐scale disturbance events provide ideal opportunities to directly study recolonisation processes in natural environments, via the removal of competitors and formation newly vacant habitat. A high magnitude earthquake central New Zealand 2016 created major ecological disturbance, with coastal tectonic uplift up ~ 6 m extirpating vast swathes intertidal organisms. One affected species was Durvillaea antarctica (rimurapa or southern bull kelp), which is an important habitat‐forming macroalga capable long‐distance dispersal. Across complex fault system varying amounts uplift, either locally extirpated heavily reduced abundance. We hypothesised that neutral priority effects chance dispersal from other populations would influence lineages establish. sampled individuals D. across zone immediately after then repeatedly new recruits same areas between 2017 2020, using genotyping‐by‐sequencing ‘before' ‘after' genomic comparisons. Our results revealed strong geographic clustering but little evidence establishing at disturbed sites, although uplifted sites remain remarkably low densities. infer has thus far primarily originated refugial, remnant patches within zone. To complement phylogeographic analysis, we estimated oceanographic connectivity among sample locations. The modelling northbound more likely, have not yet detected genotypes recolonised populations. As ongoing process transitions evolutionary timescale, change remains possible. This provides first ‘snapshots' a following large‐scale event, research potential reveal insight into both micro‐ macroevolutionary processes.
