Data from: Population genetic structure and connectivity of deep-sea stony corals (Order Scleractinia) in the New Zealand region: implications for the conservation and management of Vulnerable Marine Ecosystems
Deep-sea stony corals, which can be fragile, long-lived, late to mature and habitat-forming, are defined as vulnerable marine ecosystem indicator taxa. Under United Nations resolutions these corals require protection from human disturbance such as fishing. To better understand the vulnerability of stony corals (Goniocorella dumosa, Madrepora oculata, Solenosmilia variabilis) to disturbance within the New Zealand region, and to guide marine protected area design, genetic structure and connectivity were determined using microsatellite loci and DNA sequencing. Analyses compared population genetic differentiation between two biogeographic provinces, amongst three sub-regions (north-central-south), and amongst geomorphic features. Extensive population genetic differentiation was revealed by microsatellite variation, whilst DNA sequencing revealed very little differentiation. For G. dumosa, genetic differentiation existed amongst regions and geomorphic features, but not between provinces. For M. oculata, only a north-central-south regional structure was observed. For S. variabilis, genetic differentiation was observed between provinces, amongst regions and amongst geomorphic features. Populations on the Kermadec Ridge were genetically different from Chatham Rise populations in all three species. A significant isolation-by-depth pattern was observed for both marker types in G. dumosa, and also in ITS of M. oculata. An isolation-by-distance pattern was revealed for microsatellite variation in S. variabilis. Medium to high levels of self-recruitment were detected in all geomorphic populations, and rates and routes of genetic connectivity were species-specific. These patterns of population genetic structure and connectivity at a range of spatial scales indicate that flexible spatial management approaches are required for the conservation of deep-sea corals around New Zealand.
Data from: High intra-ocean, but limited inter-ocean genetic connectivity in populations of the deep-water oblique-banded snapper Pristipomoides zonatus (Pisces: Lutjanidae)
While many studies have investigated connectivity and subdivision in marine fish occupying tropical, shallow water reef habitats, relatively few have been conducted on commercially important deep-water species in the Indo-Pacific region. Here, we examine spatial and temporal genetic variation in the deep-water oblique-banded snapper Pristipomoides zonatus, collected from eight locations across the Indian and Pacific Oceans. A total of 292 individuals were screened for genetic variation at six nuclear microsatellite loci and the cytochrome c oxidase subunit 1 (COI) mitochondrial DNA (mtDNA) gene. There was evidence of low, but significant genetic differentiation between ocean basins (FCT = 0.009) and no significant divergences between sites within oceans. The lack of population structure within ocean basins suggests P. zonatus has a long pelagic larval duration with high levels of connectivity between populations over large geographical distances (>2000 km). There was no evidence of temporal variation in allele frequencies within populations. However, ephemeral genetic divergences between sites were detected, along with a significant reduction in genetic diversity at one site, suggesting there may be low effective population sizes (Ne). Our results suggest that localized declines in genetic diversity could be offset by gene flow from other locations within ocean basins, though predicting the broader impacts of localized stock depletions requires further understanding of recruitment dynamics and life history characteristics of the species.
