Special Issue Information

Dear Colleagues,

We invite submissions of papers using molecular data to address classic questions and processes in the ecology and evolution of fishes. This Special Issue reflects on the connections between molecular ecology and evolution as well as their applications in fish monitoring using environmental DNA, barcoding, metabarcoding, species identification and delimitation, phylogeography, and integrative taxonomy. It incorporates papers addressing specific questions at different taxonomic levels of fishes and presents new insights to understand ecological and evolutionary processes in addition to new technologies that can impact the identification and recognition of fish subclades.

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.

Cryptic Lineage and Genetic Structure of Acanthopagrus pacificus Populations in a Natural World Heritage Site Revealed by Population Genetic Analysis

Recent studies have revealed extensive genetic differentiation among some populations of marine taxa that were previously believed to be essentially homogeneous because larvae are widely dispersed in ocean currents. Acanthopagrus pacificus is a commercially and ecologically important teleost fish that is endemic to shallow coastal waters and estuaries of some tropical and sub-tropical areas in the West Pacific Ocean. Here, we examined genetic structure and the inferred demographic history of A. pacificus populations from mtDNA control region sequence data. A 677–678 base-pair fragment was sequenced from 159 individuals sampled at three localities across the West Pacific Ocean. Haplotype diversity was high, ranging from 0.915 to 0.989, while nucleotide diversity was low to medium, ranging from 0.8% to 2.60%. Analysis of molecular variance (AMOVA) showed significant genetic subdivision (FST = 0.155, p < 0.05) among sampled populations while pairwise FST estimates also revealed strong genetic differentiation among populations indicating that gene flow was restricted. Two distinct cryptic lineages were identified that were estimated to have diverged during the Pleistocene. In summary, contemporary factors including regional oceanic currents and self-recruitment are considered to have played significant roles in producing the population structure in this fish. In particular, the genetic information generated in the current study will allow appropriate fisheries management and conservation strategies to be developed for this important local fish in the waters around Iriomotejima Island, a World Heritage site.

Elopidae is the most speciose family within the Elopiformes, comprising seven valid species. Despite this reduced number of species, the family presents poorly resolved systematics, mainly owing to its wide distribution and highly conserved anatomic features. Therefore, we aimed to explore the species diversity of the Elopidae using species delimitation, genetic diversity, and phylogenetic analysis combined with DNA barcoding of the COI gene. The results from the delimitation analysis grouped the species into a single cluster, while the genetic diversity analysis among the groups showed a distance ranging between 1.29 and 2.78%. Both phylogenetic and haplotype network analysis grouped the species into four clades, associated with the distribution of the organisms. The lack of resolution in the species delimitation analysis might be directly associated with the recent radiation of the group, a hypothesis corroborated by both the low genetic diversity (close to the 2% threshold) and the few mutations that separate the haplotypes observed among the species. Interestingly, our data supported a new arrangement for the Elops species. In addition, the data available in public databases present taxonomic errors at several levels. Although some issues remain unsolved, our results can be used in the identification of taxa and provide information to assist taxonomic revisions of the Elopidae. Full article
