Special Issue Information

Dear Colleagues,

Biodiversity loss is a global problem that significantly influences human wellbeing today. Marine invertebrates comprise 92% of ocean life, playing important ecosystem functions and providing essential goods. However, invertebrate diversity is underestimated because many taxa are still poorly known. Taxonomists have alerted us to the fact that many invertebrate species may become extinct before we even know about their existence. Moreover, research is biased toward more accessible areas (e.g., intertidal) and certain geographical regions. Previous research has provided important insights into the distribution patterns of marine invertebrates in response to environmental gradients (e.g., depth, salinity, pollution). However, studies in many areas are still scarce or completely absent.

This Special Issue aims to boost knowledge about the biodiversity, taxonomy, and distribution of marine invertebrates. This information may be useful for designing more efficient conservation and management strategies.

In the above framework, this Special Issue welcomes original scientific contributions and review articles on the broad aspects of marine invertebrates, such as:

  • Taxonomic descriptions that provide ecological information about the distribution of marine invertebrates;
  • Biodiversity pattern studies, including those related to anthropogenic pressures and natural environmental gradients.

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. Journal of Marine Science and Engineering 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.

Geoduck clams are important commercial marine resources in Southeast Asia. However, the complete mitochondrial genome of the native geoduck clam in South Korea has not been reported yet. This study reports a geoduck clam collected from the east coast of South Korea. Based on its morphological characteristics and molecular data, the geoduck clam was identified as Panopea sp. belonging to the bivalve family Hiatellidae. We determined the complete mitochondrial genome of this species and investigated the seasonal reproductive pattern for monthly changes in sex ratio, gametogenesis, and reproductive cycle from September 2019 to August 2020. The total length of the complete mitochondrial genome sequence is 16,006 bp, containing 13 protein-coding, 22 transfer RNA, 2 ribosomal RNA, and a control region (D-loop). A molecular phylogenetic comparison with 10 bivalve species showed that the geoduck clam specimen belongs to the family Hiatellidae, clustering with Panopea abrupta Chinese strain, P. generosa, and P. globosa. The gametogenesis of the geoduck clam was identified in six stages by histological analysis. The sex ratio was biased towards males from May 2019 to July 2019, the main spawning activity from the frequency of the gonads with ripe and spent stages occurred from October 2018 to April 2019, and there was no clear pattern of spawning peaks from May to August 2019 with gonads developed asynchronously between both sexes. This is the first study to report new records of the genus Panopea based on the complete mitochondrial genome and to examine the seasonal reproductive pattern of the native geoduck clam Panopea sp. in South Korea, providing valuable information for its sustainable management in South Korea.
