Interests: ecology and conservation of freshwater systems; malacology, in the areas of biodiversity, evolution patterns, population dynamics, dispersion patterns and adaptations to hydrological regimes, life cycles and parasitology; research on bivalves from the order Unionoidea (freshwater mussels or Naiads), in the areas of systematics, reproductive biology, ecology and conservation biology

Special Issue Information

Dear Colleagues,

Freshwater mollusks include bivalves and gastropods and comprise a remarkable diversity of ecological strategies and adaptations, because of different evolutionary histories and adaptations to highly variable environments. Freshwater habitats include rivers and streams, lakes and ponds, springs, and a variety of artificial structures such as fountains and canals. They show different hydrological regimes, from permanently flowing to temporary and intermittent, presenting a wide array of challenges to mollusks living in them. Some species such as freshwater mussels have very specific ecological requirements and a complex life cycle that depends on an obligatory parasitic stage, making them one of the most endangered animal groups in the world. Others are often geographically very restricted, with numerous endemic species, such as some freshwater gastropods, contrasting with widespread species like some Sphaeriidae. A few have converted into some of the most problematic invasive species in the world, most notably the zebra mussel Dreissena polymorpha, causing severe ecological impacts and multi-million-dollar economic losses. Often, the conservation of freshwater mollusks is imperilled by the poor knowledge of their ecological requirements, so filling the gaps for the least studied groups is of the upmost importance.

This special issue presents a great opportunity to bring together novel contributions about the ecology of freshwater mollusks, and their conservation, both regarding bivalves and gastropods, native or invasive species. We kindly invite you to submit manuscripts about the above-mentioned topics, and specially encourage wide-scale applicable case-studies and integrative approaches using multi-disciplinary studies. If you are interested in this opportunity or have any doubts, 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.

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.

Simpsonaias ambigua (Salamander Mussel) is a freshwater mussel of the Family Unionidae endemic to North America, and it is considered endangered across most of its range. This species is unique among the Unionidae, because it uses the salamander, Necturus maculosus (Mudpuppy), as its larval host rather than fish like all other unionids. The overall goal of this study was to obtain baseline data on the current distribution and life history traits of S. ambigua in Ontario, Canada. These data are critical for future recovery efforts to protect, restore, or augment populations of S. ambigua across its range. Conventional survey methods were adapted to target S. ambigua, and an additional method was employed to detect this species: trapping N. maculosus and inspecting for signs of encysted glochidia. Both methods were successful at detecting S. ambigua when they were present. Furthermore, Simpsonaias ambigua’s life history traits were investigated, and more information is now available on the reproductive timing windows related to gonad and glochidia development and the host infestation period, as well as on longevity.

Herbert D. Athearn (1923–2011) was an avid student of freshwater mollusks. He named his private shell collection “The Museum of Fluviatile Mollusks”, which was meticulously organized at his residence. This collection was curated to current museum standards with detailed labels, all lots with catalog numbers, and all unionoid valves with catalog numbers written in India ink. Specimens’ collecting dates span between 1850 and 2005, with 23,344 cataloged lots containing over 3000 lots of imperiled and extinct taxa. All data for each of the lots are handwritten in paper catalogs. Many lots contain growth series from the smallest juveniles to the largest specimens seen. He traded extensively with collectors worldwide, obtaining specimens from 84 countries. This collection was donated to the North Carolina Museum of Natural Sciences in 2007. To date, 64 percent of this collection has been databased using a relational database, totaling 589,995 specimens. The collection consists of bivalves, primarily Unionidae, Margaritiferidae, and Sphaeriidae, as well as gastropods. There are 73 families represented, with the greatest abundance found in freshwater Pleuroceridae. The Athearn collection donation included his correspondence, his library, field notes, and USGS topographic maps with marked field localities. Full article
