Special Issue Information

Dear Colleagues,

Live-bearing fishes have long been a model system for evolutionary biology, particularly for the study of natural selection in the wild. This group, which includes swordtails, mosquitofish, guppies, mollies, and their relatives, consists of small tropical freshwater fishes that are popular in the aquarium trade and that have been introduced as mosquito control across the world.  

Their ability to adapt to a variety of habitats has led them to be used to address many evolutionary biology and adaptation questions, including on convergent evolution, invasion biology, rapid evolution, and adaptation to extreme environments. Additionally, their variable life-history, which includes both viviparous and oviparous species, along with their easily observable sexually selected characteristics, make them well-suited to studies on placentation, sperm selection, sexual antagonism, and colour patterning, with the latter even providing insights into the fundamental biology of cancer. 

Poecillids are now on the cusp of becoming models for adaptation genomic, with at least 10 reference genome assemblies available, including some at the whole chromosome level. These genomic resources, coupled with high-throughput sequencing techniques, have provided insights into a broad range of evolutionary genetics questions such as sex chromosome evolution, hybridisation, phenotypic plasticity, and selection at the genomic level across these species.  

The aim of this Special Issue is to explore evolutionary genetics and genomics in Poeciliids, and it covers a variety of approaches, including phylogenetics, comparative genetics, or population genetics.

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 papers will be 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. Genes 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 2000 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.
