Special Issue Information
Dear Colleagues,
Chondrichthyans, and especially elasmobranchs, are one of the most threatened marine taxa. Actions must be taken rapidly to ensure the long-term survival of these organisms, protecting both their morphologic and genetic diversity. To do so, stakeholders need the most precise information about organisms’ distribution and population connectivity to establish efficient management and conservation strategies, which stems from a taxonomy accurately representing the diversity of the group of interest.
Species delimitation is a vital enterprise within evolutionary biology and conservation: it bridges the historically independent disciplines of systematics, phylogeography and population genetics. While seminal studies combining molecular and morphological data highlighted the cryptic diversity of globally distributed morpho-species more than a decade ago, chondrichthyan taxonomy and identification are still mostly based on morphology. When such cryptic diversity is at risk of extinction, the disjunction between molecular systematics research and conservation policy becomes a significant problem: an integrative approach combining species hypothesis testing and population genetics is necessary to efficiently protect this genetic richness. Therefore, considering the ecological importance of chondrichthyans, we present this Special Issue focused on various aspects of their genetic diversity, aimed towards integrating taxonomy advances in conservation planning.
The scope includes, but is not limited to, the following fields: integrative taxonomy, species diversity and distribution, biogeographic patterns, evolutionary history, population genetics and conservation. If you are interested in this opportunity or have any questions, please do not hesitate to contact us.

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 2100 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.
