Special Issue Information

Dear Colleagues,

Speciation and formation processes of contemporary communities are among the most important fundamental problems of biology. During the last quarter of the century, the advent of molecular phylogenetic methods has generated a drastic increase in the number of studies devoted to the evolutionary history of taxa of various ranks, as well as their taxonomic diversity and distribution. Phylogenetic and phylogeographical approaches may provide a new insight into the speciation of marine taxa and the history of marine communities. The dispersion of animals and their isolation under the influence of global climatic and tectonic changes are directly related to the extinction of taxa and the formation of new ones, which means that they are as equally important as descriptive systematics, ecology, and functional morphology in evolutionary and faunistic research. For this Special Issue, we invite manuscripts that advance our current knowledge on the biodiversity, taxonomy, evolution, and phylogeny of marine invertebrates, either on their own or in any combination.

Retusa pertenuis is still formally considered a junior subjective synonym of Retusa obtusa, despite previous data indicating R. pertenuis and R. obtusa differ significantly in copulatory system morphology. In this paper, we study the species identity and population structure of R. pertenuis with an integrative approach combining morphological and molecular data. The external morphology, head copulatory system and gizzard plates were studied using light microscopy and scanning electron microscopy. We also obtained two mitochondrial (COI and 16S) and two nuclear (H3 and 28S) markers to test the monophyly of R. pertenuis and R. obtusa. Populations from the White Sea, Sea of Okhotsk and Sea of Japan were studied using COI and 18S molecular markers. Our results show that Retusa obtusa sensu lato represents a species complex of at least four species: the nominative species occurring in the North Atlantic, the widely distributed R. pertenuis and two additional species whose identities should be clarified in further studies. Retusa pertenuis geographic range encompasses the North Atlantic, Eurasia’s northern seas, the Canadian Arctic, the Bering Sea, the Sea of Okhotsk and the Sea of Japan. Within R. pertenuis’s range, this species demonstrates a wide variability in shell morphology. Full article

During an investigation of a natural sandy beach on Jeju Island, South Korea, a species of marine nematode belonging to the rare genus Manunema was discovered and is now being reported. Up until now, no molecular sequences of this genus have been available, and its position within the nematode system has been a subject of dispute. Currently, Manunema is classified within the order Plectida, either as the only genus of the family Peresianidae in the superfamily Haliplectoidea or directly as a genus of the family Leptolaimidae. Here, we report on the discovery of Manunema cf. proboscidis Gerlach, 1957, which was found off Jeju Island, South Korea. We also conduct an in-depth investigation of its peculiar morphology, with a particular focus on the reproductive system type observed within the species. Additionally, we examine the phylogenetic relationship of the genus using 18S rRNA sequences. Partial mtCOI, nearly complete sequences of the 18S ribosomal RNA gene as well as a partial 28S (D2–D3 region) gene are provided. Morphologically, the presence of tubular precloacal supplements (shared by superfamily Leptolaimoidea and not Haliplectoidea) and antidromously reflected ovaries of females in Manunema (shared by the order Plectida and not Desmoscolecida) may have taxonomic significance. Our phylogenetic trees based on 18S rRNA also reflected this, including Manunema in a well-supported monophyletic clade of the family Leptolaimidae. Full article

Hydrozoans are widely known for their complex life cycles. The life cycle usually includes an asexual benthic polyp, which produces a sexual zooid (gonophore). Here, we performed an extensive analysis of 183 specimens of the hydrozoan genus Sarsia from the White Sea and identified four types of gonophores. We also compared the type of gonophore with haplotypes of the molecular markers COI and ITS. Analysis of COI sequences recovered that the studied specimens related to the species S. tubulosa, S. princeps and S. lovenii, and that the S. lovenii specimens divided into two COI haplogroups. More intraspecific genetic diversity was revealed in the analysis of the ITS sequences. The Sarsia tubulosa specimens divided into two ITS haplotypes, and presumably, hybrid forms between these lineages were found. For S. lovenii, we identified 14 ITS haplotypes as a result of allele separation. Intra-individual genetic polymorphism of the ITS region was most likely associated with intraspecific crossing between the different haplotypes. The diversity of the morphotypes was associated with the genetic diversity of the specimens. Thus, we demonstrated that the morphologically variable species S. lovenii is represented in the White Sea by a network of intensively hybridizing haplotypes. Hybridization affects the morphology and maturation period of gonophores and presumably affects the processes of speciation. Full article

During an investigation of the intertidal zone at Yeongjongdo Island, Incheon, Korea, a new species belonging to the genus Paracanthonchus was found and is reported. Paracanthonchus Mikoletzky, 1924 is the largest genus within the family Cyatholaimidae, and the species identification of this genus has been difficult mainly due to overlapping characteristics and a lack of genus/species-defining apomorphic characters. The new species is characterized by the buccal cavity, armed with one large dorsal tooth and two subventral teeth, the presence of lateral differentiation, seventy-six tubular precloacal supplements, and proximally paired gubernaculum. Alongside the description, we are updating the review of the genus by providing an up-to-date list of valid species, as well as a comprehensive tabular key to the genus with measurements of species-discerning characteristics. We also provide partial sequences of mtCOI, 18S and 28S rRNA to verify the new species belongs to the genus Paracanthonchus and to discuss the phylogeny of the family Cyatholaimidae as well as the genus Paracanthonchus. Our phylogeny agrees with previous findings that, while Cyatholaimidae forms a monophyletic clade, many genera within, including Paracanthonchus, are paraphyletic. For now, it appears that subfamilies are not well-represented by molecular means, and much more molecular data along with species defining morphological traits will have to be accumulated to meaningfully organize this family and the genus within.

Thirty-one nominal species of the benthic harpacticoid family Zosimeidae Seifried, 2003 are known from several coastal systems less than 200 m depth and the deep sea. Several copepods of the family Zosimeidae were found in deep-sea sediment samples from the Gulf of Mexico and the Gulf of California (Mexico). The Mexican material represents new species of the genera Zosime Boeck, 1873, Peresime Dinet, 1974, Heterozosime Kim and Lee, 2021, and Acritozosime Kim and Lee, 2021. Standardized and complete descriptions for these new species are provided. Previous studies have shown that the genus Zosime can be subdivided into two species groups. We performed phylogenetic analyses (88 characters and 42 taxa) to test the naturalness of such subdivision, to subdivide these groupings further, and to shed some light on the phylogenetic relationships among the zosimeid genera and their species. Our results confirmed (i) the monophyly of previous subdivisions of the genus Zosime, and (ii) that the genus Zosime can be further subdivided into two major subgroups composed of several subordinate clades. Additionally, some comments on the phylogenetic hypotheses amongst the species of each genus reported here, are provided. Full article

In the Russian Arctic seas and adjacent areas of the Arctic basin, 120 sites of siboglinid records are currently known. Individuals belonging to 15 species have been collected. The largest number (49.2%) of records were made in the Barents Sea, followed by the Laptev Sea (37.5%) and the Arctic basin (10 records; 8.3%). No siboglinids have been reported from the Chukchi Sea. The largest number of species has been identified in both the Laptev Sea and Arctic basin (seven species each). Seventy-eight percent of the records were discovered at water depths down to 400 m. Many of the siboglinid records in the Arctic seas of Russia are associated with areas of high hydrocarbon concentrations. In the Barents Sea, Nereilinum murmanicum has been collected near the largest gas fields. The records of Oligobrachia haakonmosbiensis, N. murmanicum, Siboglinum ekmani, Siboglinum hyperboreum, Siboglinum norvegicum, as well as two undetermined species of siboglinids are associated with the marginal areas of bottom gas hydrates where methane emissions can occur. The Arctic seas of Russia feature vast areas of permafrost rocks containing gas hydrates flooded by the sea. Under the influence of river runoff, gas hydrates dissociate, and methane emissions occur. Crispabrachia yenisey and Galathealinum karaense were found in the Yenisei estuary, and O. haakonmosbiensis was found in the Lena estuary. Full article
