Special Issue Information

Dear Colleagues,

The Special Issue “Featured Papers in Taxonomy, Evolution, and Biogeography Section” will present a collection of feature papers on recent research addressing the taxonomy, evolution, and biogeography of fishes. Our focus is on fishes, whether inhabiting freshwater, estuarine or marine systems, and various approaches, including traditional taxonomic and more modern molecular approaches.

This Special Issue is seeking papers that feature original research as well as review articles. The journal offers high-quality peer review and a rapid publication process. Submissions to this Special Issue are now open and will remain so until 31^st January 2023. Invited papers may be considered for a full or partial waiver of the publication fee. If you would like to be invited to contribute to this Special Issue, please send the (tentative) title and abstract of your potential paper/review to the Guest Editor listed below. We look forward to receiving your contribution.

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. Fishes 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 1800 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

In order to study the genetic structure and population geographic distribution pattern of coastal mussel populations in the coast of China, mitochondrial DNA (COI and Cytb genes) were used to analyze the genetic diversity, genetic structure, and population history dynamics of Mytilus unguiculatus in the East China Sea and the Yellow Sea. We detected high levels of genetic diversity in seven populations of M. unguiculatus. A total of 34 haplotypes of COI genes and 29 haplotypes of Cytb were obtained. The haplotype diversity of COI ranged from around 0.77 to 0.93 (Cytb: 0.83~0.91). The nucleotide diversity of COI ranged from around 0.0044 to 0.0064 (Cytb: 0.0049~0.0063). The coefficient of genetic differentiation (F_ST) of COI ranged from around 0.031 to 0.080, and Cytb ranged from around 0.028 to 0.039. Analysis of molecular variance (AMOVA) and a phylogenetic tree showed that the genetic structure was relatively weak, and there was no clear population differentiation. The neutrality test results showed that Tajima’s D value and Fu’s Fs value were not significant, and no significant population demographic events, including population expansion or population bottleneck, were detected in the samples. The Bayesian skyline graph analysis showed that the effective population size has been relatively stable for nearly 10,000 years, without any large population fluctuations. It was speculated that the seven populations in the present study should belong to the same group. This study provides a comprehensive survey of the genetic characteristics of M. unguiculatus, filling the gaps among related studies. It provides theoretical support and material accumulation for seed selection and breeding, genetic resources’ protection, and breeding management in the future. Full article

Abstract

A recent field inventory focusing on catfishes of the trichomycterine genus Cambeva detected the occurrence of two morphotypes, C. barbosae and C. cubataonis, in the Guaratuba-Babitonga-Itapocu area (GBIA) of southern Brazil, reporting some discordance with results of coalescent-based approaches for species delimitation that indicated different estimates of species number. Contrastingly, based on examination of characters taken from the external morphology and osteology, we here recognised six species of Cambeva in GBIA: C. cf. botuvera, a polymorphic and geographically widespread species; C. cubataonis, endemic to the Rio Cubatão do Norte; and four new species, two endemic to the Rio Itapocu basin, one endemic to the Baía de Babitonga system and one endemic to the Baía de Guaratuba system. We performed a molecular phylogenetic analysis indicating that Cambeva comprises three major clades, the alpha-, beta- and gama-clades, with C. cf. botuvera and a clade comprising C. cubataonis and three new species belonging to the beta-clade and another new species belonging to the gama-clade. We concluded that species here recognised are not in fact incongruent with results of that recent study when taxa are correctly identified by a representative sample of morphological characters, highlighting the importance of osteological characters for delimiting trichomycterine species.
