Heightened interest in the exploitation of deep seafloor minerals is raising questions on the consequences for the resident fauna. Assessing species ranges and determination of processes underlying current species distributions are prerequisites to conservation planning and predicting faunal responses to changing environmental conditions. The abyssal central Pacific nodule belt, located between the Clarion and Clipperton Fracture Zones (CCZ), is an area prospected for mining of polymetallic nodules. We examined variations in genetic diversity and broad-scale connectivity of isopods and polychaetes across the CCZ. Faunal assemblages were studied from two mining claims (the eastern German and French license areas) located 1300 km apart and influenced by different productivity regimes. Using a reverse taxonomy approach based on DNA barcoding, we tested to what extent distance and large-scale changes in environmental parameters lead to differentiation in two macrofaunal taxa exhibiting different functions and life-history patterns. A fragment of the mitochondrial gene Cytochrome Oxidase Subunit 1 (COI) was analyzed. At a 97% threshold the molecular operational taxonomic units (MOTUs) corresponded well to morphological species. Molecular analyses indicated high local and regional diversity mostly because of large numbers of singletons in the samples. Consequently, variation in composition of genotypic clusters between sites was exceedingly large partly due to paucity of deep-sea sampling and faunal patchiness. A higher proportion of wide-ranging species in polychaetes was contrasted with mostly restricted distributions in isopods. Remarkably, several cryptic lineages appeared to be sympatric and occurred in taxa with putatively good dispersal abilities, whereas some brooding lineages revealed broad distributions across the CCZ. Geographic distance could explain variation in faunal connectivity between regions and sites to some extent, while assumed dispersal capabilities were not as important.

Distributional ranges of selected deep-sea annelids are examined in an integrative approach using genetic markers (COI, 18S) and morphology. The source material comes from various deep-sea expeditions to the Pacific and Atlantic Oceans realized between 1998 and 2015. Selection criteria for the eventual target species are a reliably documented widespread distribution in the deep-sea, and the presence in sufficient numbers of specimens in our source material. Specimens from museum collections are also incorporated. Species studied are Sigambra magnuncus, Bathyglycinde profunda and B. sibogana, Progoniada regularis, P. cf. regularis, and Spiophanes cf. longisetus, plus three newly described species: Octomagelona borowskii sp. nov., Spiophanes australis sp. nov., and Spiophanes pacificus sp. nov. Illustrated descriptions are provided and the morphological distinction to congeners discussed. Genetic diversity is highest in most frequently found species, also reflected by the large numbers of genetically divergent haplotypes. The majority of haplotypes are singletons. Pan-oceanic distribution is observed for Progoniada regularis, Bathyglycinde profunda and Sigambra magnuncus, but even species restricted to a single ocean have distributions spanning hundreds or even thousands of kilometres. Our data suggest multiple and possibly ongoing dispersal and genetic exchange between oceans, most cogent for Sigambra magnuncus.
