“…The South Island of New Zealand is tectonically active with occasional large earthquakes affecting the eastern coast (figure 1a), as at Christchurch in 2011 and Kaikoura in 2016 (figure 1b). A large prehistoric earthquake approximately 800 years ago raised a substantial stretch of southern coastline by 2-3 metres [25][26][27] (figure 1c,d). The whole stretch of coast was affected by an approximately 800 yr BP event [26] dated by radiocarbon methods at the fault line itself [27] (figure 1c).…”

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 capitalized on a major prehistoric (800 yr 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.

“…This region has been subject to several major events of sudden uplift throughout the Holocene (McSaveney et al 2006). Hay (2020) and Parvizi et al (2019) give evidence for uplift in the region structuring the population of southern bull-kelp and causing discrete areas where the species is absent. Uplift events may have structured populations of benthic invertebrates in similar ways, but comprehensive sampling across the region would be required to give support to this idea.…”

“…Evidence for historical uplift events and subsidence can be seen around New Zealand, such as the Whanganui marine terraces and terraces along the Wairarapa south coast (Grapes 1999;McSaveney et al 2006;Pillans 2017). Sudden events like these can have profound effects on coastal communities and might even lead to significant loss of genetic diversity in these areas (McSaveney et al 2006;Parvizi et al 2019;Hay 2020).…”

The endemic New Zealand sea snails Haustrum scobina and Haustrum albomarginatum are rocky shore intertidal dogwhelks of the Muricidae family. They have direct developing young and are carnivores. Their radula is used to drill into the shells of their prey, and they are commonly referred to as oyster borers. The taxonomic status of these species is still unresolved and therefore the name Haustrum scobina sensu lato is used. The overall goal of this thesis research was to investigate the phylogeny and phylogeography of Haustrum scobina sensu lato using mitochondrial DNA sequences. Comparisons made to phylogeographic studies of ecologically similar species such as Cominella spp. provide an opportunity to identify the common environmental determinates of population migration route, genetic differentiation and speciation whenever similar patterns are found. A nation-wide collection of samples was used to generate 277 new sequences from a 610 bp portion of the cytochrome c oxidase subunit I (COI) gene. This enabled the formation of a dataset of 654 DNA sequences, which was comprised of the 277 new sequences, 16 retrieved from a published study that deposited them in GenBank, and 361 from a previous unpublished thesis study. An unexpectedly diverse phylogeny of 58 COI haplotypes from 31 sample sites was recovered. These formed three clusters using K-means clustering by pairwise mutational distance. The in-group species did not form reciprocal monophyly groups, and the expected closest outgroup species (Haustrum haustorium) appeared to be as similar to the in-group clusters as they were to each other. A dataset of 27 DNA sequences from an 827 bp portion of the large sub-unit 28S nuclear rRNA gene was produced with the intention of corroborating the findings from the analyses of the COI dataset. This consisted of 26 new sequences and one sequence from a published study that deposited the sequence on GenBank. The expected taxonomic arrangement of Haustrum scobina sensu lato could not be matched by COI sequences due to incongruence with the 28S phylogeny and shell morphology. The 28S dataset and shell morphology indicated there are two species in Haustrum scobina sensu lato. These are most likely Haustrum scobina and Haustrum albomarginatum, but they could not clearly be identified in the COI data. As a result, the phylogeographic certainty was limited when using the COI dataset because of the lack of clarity between the haplotypes of the two putative species. Possible reasons for the complicated COI dataset are discussed. Phylogenetic analysis of both the 28S and COI datasets did not support the expected conclusion that members of Haustrum scobina sensu lato are each other’s closest relatives. Haustrum haustorium was the expected immediate outgroup species but formed a polytomy with the in-group. A decrease in COI haplotype diversity was observed in southern samples when they were compared to the samples collected at northern locations. Taranaki sites shared a haplotype with multiple South Island sites that had no haplotype diversity. This suggested post-glacial re-colonisation of southern sites after displacement by ice-age conditions from these locations, a hypothesis consistent with results from studies of the Cominella genus. Association between Purau Bay in Lyttleton Harbour, Titahi Bay, Port Ahuriri and Kawau Island with no associated haplotypes between these locations suggested human-mediated translocation events. A genetic disjunction was also apparent between the south Wellington/Wairarapa coast and the eastern Wairarapa coast. This pattern was consistent with one study of Cominella maculosa and other studies have attributed similar patterns of other species in the region to recent uplift events affecting coastal community composition. The phylogeny of Haustrum scobina sensu lato will require further investigation before it can be used to more confidently resolve the phylogeographic history of the species.

“…Such complex interactions have been traced in the effects of contemporary habitat disruptions such as heat waves on both forest-forming macroalgae (Wernberg et al2018;Gurgel et al 2020;Smale 2020) and their associated macroinvertebrate communities (Ettinger-Epstein & Kingsford 2008;Smaleet al 2017). Previously, genetic data have revealed that historical habitat perturbations can underpin phylogeographic structuring of intertidal macroalgae (Parvizi et al 2019(Parvizi et al , 2020, although the effect of such disturbances on the dynamics and assembly of kelp-associated benthic communities (epibiota) remains unclear. In the present study, we carry out new genomic analyses at the macroinvertebrate community level to test for multi-species responses to a major historic disturbance caused by coastal uplift approximately 900 yr BP.…”

The elimination of lower trophic levels following severe habitat disturbance can trigger new community assembly processes. However, little is known about how past habitat disturbances have affected codependent evolution of trophically-linked and closely interacting taxa. Using genome-wide analysis of a macroalgal community affected by ancient catastrophic coastal uplift, we track the ecological dynamics of past co-dispersal and co-diversification among obligate interacting taxa. Our study reveals rapid and concerted reassembly of an intertidal community following disturbance. Specifically, hierarchical co-demographic analyses of multispecies genomic data support synchronous expansions of four strictly intertidal species in the wake of tectonic disturbance. These data show that tight algal-epifaunal links underpin parallel demographic responses across distinct trophic levels. These results highlight that high-resolution comparative genomic data can elucidate the strength of obligate ecological interactions, and the evolutionary dynamics of past co-dispersal and co-diversification in post-disturbance communities.
