Special Issue Information

Dear Colleagues,

Isopod crustaceans are an integral part of many deep-sea ecosystems. They are widely distributed, including in terrestrial, freshwater, and marine habitats, but appear to be particularly diverse in areas beyond the shelf break (commonly defined as the deep sea), where they exhibit a wide variety of morphologies and functions. Due to their ubiquity, isopods have been widely used to study large-scale patterns of biodiversity and biogeography in deep-sea environments, and more recently even to evaluate anthropogenic impacts on deep-sea fauna. Several hundred deep-sea species have been described so far, but it is clear that this represents only a small fraction of the deep-sea isopod diversity, since most isopod species brought to light are new to science. In addition, pending systematic revisions, as well as unsolved species complexes and phylogenetic relationships across families, emphasise that there is still a great need for research here.

For this Special Issue, we welcome contributions that will help deepen our knowledge and understanding of isopod crustacean biodiversity. In addition to taxonomic examination of isopods, as the cornerstone of any biological research, we welcome further phylogenetic work elucidating their origins in the deep sea up and the analysis of biodiversity patterns aiming to achieve a more comprehensive picture of the general drivers of deep-sea benthic biodiversity. Descriptions and new evidence of the distribution of individual species will only be considered if they are placed in a broader context and thus contribute significantly to the understanding of the biogeography and diversity of the deep sea. We are particularly interested in new approaches and methodologies that advance diversity research in this taxon, and look forward to receiving studies from poorly known regions and habitats that help to fill biogeographical gaps.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Diversity is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
Three new species of the rare deep-sea family Haplomunnidae are described from the abyssal of the Northwestern (NW) Pacific adjacent to the Kuril–Kamchatka Trench (KKT) based on material collected during the deep-sea expeditions KuramBio (2012) and SokhoBio (2015). Previously, only three species of [...] Read more.
Three new species of the rare deep-sea family Haplomunnidae are described from the abyssal of the Northwestern (NW) Pacific adjacent to the Kuril–Kamchatka Trench (KKT) based on material collected during the deep-sea expeditions KuramBio (2012) and SokhoBio (2015). Previously, only three species of the genus Haplomunna Richardson, 1908 were described in the whole North Pacific, including one species from its western part. Haplomunna kurilensis Golovan and Malyutina sp. nov., closely resembling H. japonica (Gamô, 1983) from the upper hadal of the Japan Trench, was the most numerous haplomunnid species in the studied region. Thylakogaster wilsoni Malyutina and Golovan sp. nov., and Abyssaranea minuta Golovan and Malyutina sp. nov., are the first species of their genera described from the Pacific Ocean. For H. kurilensis sp. nov. and T. wilsoni sp. nov., DNA sequences were obtained for 18S rRNA and 28S rRNA genes. The phylogenetic relationship between these species, as well as their position within the Haplomunnidae, were reconstructed using 18S rDNA. Full article
