dc.description.abstract | Anthropogenic activities such as mining pose a putative threat to deep-sea ecosystems and baseline studies of key indicator species are required to assess future loss of biodiversity. We examined population genetic structure, connectivity, cryptic diversity and phylogeography of the deep-sea scavenging amphipod, Abyssorchomene distinctus, using DNA sequence data (mitochondrial COI and nuclear 28S genes) from 373 specimens collected from six abyssal basins. We observed a striking absence of cryptic diversity, suggesting a single, widely distributed species in the Pacific and Indian Ocean. A single event of population expansion across distances up to 24,000 km is further supported by a main ancestral haplotype in the star-like shaped COI haplotype network, a skewed nucleotide mismatch distribution and deviations from evolutionary neutrality tests. In the Pacific, A. distinctus showed weak genetic population structure and low differentiation between the basins of the Clarion-Clipperton Zone and the DISCOL Experimental Area, suggesting a possible higher chance of recovery from deep-sea mining impacts. However, since our data indicate a single recent historic population expansion event, A. distinctus populations will likely be affected to unknown extents, as the exact drivers shaping distribution and dispersion of A. distinctus are still unclear. | - |
dc.description.sponsorship | We would like to acknowledge funding by the Belgian Science and Policy Ofce (BELSPO) for both JPI-Oceans “Mining Impact” Projects (BR/15/MA/JPI-DEEPSEA1 and BR/15/MA/JPI-DEEPSEA2). We would like to thank the crew of the Research Vessel “Sonne” for their support during sampling. The authors thank Henri Robert for assistance during the feld campaign and Cedric d’Udekem d’Acoz for taxonomic identifcations. We furthermore are grateful to Ms. Dorien Aerts for the provided guidance to Deborah W. E. Dupont in morphological verifcation and dissection as well as practical support during molecular work. | - |
