Special Issue Information
Dear Colleagues,
“It was formerly believed that the same fresh-water species never existed on two continents distant from each other. But Dr. Günther has lately shown that the [sic] Galaxias attenuatus inhabits Tasmania, New Zealand, the Falkland Islands, and the mainland of South America. This is a wonderful case, and probably indicates dispersal from an Antarctic centre during a former warm period. This case, however, is rendered in some degree less surprising by the species of this genus having the power of crossing by some unknown means considerable spaces of open ocean”. (Darwin, 1872)
These prescient words by Darwin, nearly 150 years ago, thrust galaxiid fishes to centre-stage in the biogeographic debate. His insight reflects two special features of the group: their Gondwanan distribution and diadromous life history. Molecular phylogenetic approaches have started to resolve the interplay between these two attributes over the last 20 years. Having a reliable phylogeny for a group, and so defining their systematics, is crucial to understanding not only biogeographic history, but also morphological and life history evolution.
This Special Issue will cover all aspects of biogeography, phylogenetics, speciation and diversity in the group. We welcome substantive new empirical contributions, as well as overall reviews on any of these topics. This issue also serves as a memorial to Dr Robert (Bob) McDowall (1939–2011), in recognition of his contribution and leadership to research on all aspects of galaxiid biology.

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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
