Special Issue Information

Dear Colleagues,

Rotifera are an amazing Phylum containing more than 2000 valid species described up to date. They are microscopic organisms found in both marine and freshwater systems, from large permanent lakes to small temporal puddles, from natron to acidic lakes, and from hyperoligotrophic lakes to sewage ponds. They represent a taxonomic challenge in several ways, while the limited number of morphological traits along with the vast range of plasticity halts the identification of their true diversity. Molecular tools assist, to that end, in unravelling a great number of cryptic species in the Phylum. Combined in an integrative approach with morphology and ecology, they contribute to accurate species description, which is fundamental in order to explain patterns of biological diversity and biogeography, understand population genetic processes, detect ecological divergence, and ultimately assess the ways in which ecosystems function. Rotifers, due to their short generation time and their reproductive mode, show rapid local adaptations, making them useful indicators of environmental change. The patterns of rotifer diversity can identify disturbance in aquatic ecosystems and assist in trophic state and water quality assessment, while the rotifer community (both in terms of composition and seasonal succession) plays a very important role in ecosystem functioning.

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. 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 1400 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.

This study shows the results of a rotifer faunistic survey in thalassic waters from 26 sites located in northeastern U.S. states and one in California. A total of 44 taxa belonging to 21 genera and 14 families were identified, in addition to a group of unidentifiable bdelloids. Of the fully identified species, 17 are the first thalassic records for the U.S., including Encentrum melonei sp. nov. and Synchaeta grossa sp. nov., which are new to science, and Colurella unicauda Eriksen, 1968, which is new to the Nearctic region. Moreover, a refined description of Encentrum rousseleti (Lie-Pettersen, 1905) is presented. During the survey, we characterized samples by different salinity values and ecosystems and compared species composition across communities to test for possible ecological correlations. Results indicate that both salinities and ecosystems are a significant predictor of rotifer diversity, supporting that biodiversity estimates of small species provide fundamental information for biomonitoring. Finally, we provide a comprehensive review of the diversity and distribution of thalassic rotifers in the United States. The results of the present study increase the thalassic rotifer record for the U.S. from about 105 (87 at species level) to 124 (106 at species level) taxa. Full article
