Data from: The genomic footprint of coastal earthquake uplift

Theory suggests that catastrophic earth-history events can drive rapid
biological evolution, but empirical evidence for such processes is scarce.
Destructive geological events such as earthquakes can represent
large-scale natural experiments for inferring such evolutionary processes.
We capitalised on a major prehistoric (800 y BP) geological uplift event
affecting a southern New Zealand coastline to test for the lasting genomic
impacts of disturbance. Genome-wide analyses of three co-distributed
keystone kelp taxa revealed that post-earthquake recolonization drove the
evolution of novel, large-scale intertidal spatial-genetic ‘sectors’ which
are tightly linked to geological fault boundaries. Demographic simulations
confirmed that, following widespread extirpation, parallel expansions into
newly vacant habitats rapidly restructured genome-wide diversity.
Interspecific differences in recolonization mode and tempo reflect
differing ecological constraints relating to habitat choice and dispersal
capacity among taxa. This study highlights the rapid and enduring
evolutionary effects of catastrophic ecosystem disturbance, and reveals
the key role of range expansion in reshaping spatial genetic patterns.
