Special Issue Information

Dear Colleagues,

Ciliates (Ciliophora) are one of the most diverse groups of protists. Different ciliates occur in various ecological niches, and they are widespread and abundant in many environments, from deserts to the polar oceans, and from bromeliad tank water to the rumen of cattle. They are an indispensable link in aquatic food webs. Short generation times make ciliates ideal bioindicators. Some ciliates live as symbionts in animals, or they can host pro- and eukaryotic symbionts themselves. Although ciliates can be morphologically identified because of their characteristic and robust shape due to the cell cortex structure and other features, the existence of cryptic or genetically isolated sibling species is quite common. Thus, Ciliophora is a group of choice when studying speciation processes and their underlying mechanisms. Moreover, the unique separation of two coexisting nuclei into germline and soma made ciliates an evolutionarily successful group. This nuclear dualism makes the genetics of ciliates unusual, but, at the same time, ciliates serve as fascinating model organisms, continuously providing genetic and epigenetic insights. A number of ciliate genomes have already been sequenced, and the data is continuously accumulating.

It is our pleasure to invite all interested colleagues to contribute to the Special Issue, “Diversity, Ecology and Genetics of Ciliates”. We aim to provide a platform highlighting new research and significant advances in the diversity, taxonomy, and genetics of ciliates. We invite submissions of research articles, reviews, or short communications on ciliate diversity, genomics, speciation, and evolution. Furthermore, reports on ciliate communities from various biotopes and habitats, and interactions among ciliates and other microorganisms will be gladly considered.

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.

Ciliates of the order Pleurostomatida play essential functions in microbial food webs from a variety of habitats and have been thought to possess a high level of diversity. Due to undersampling and often absent molecular data, the actual diversity and phylogenetic relationships within this group remain unclarified. To help address this deficiency, a survey of freshwater pleurostomatid ciliates was undertaken in Lake Weishan Wetland, northern China. Here, two new Amphileptus species, Amphileptus sinicus sp. nov. and Amphileptus piscinarius sp. nov., were investigated using modern morphological and molecular techniques. Amphileptus sinicus sp. nov. is characterized by possessing a comparatively large cell size of 330–490 μm, contractile vacuoles on both ventral and dorsal margins, and 8–10 left and 42–61 right kineties. Amphileptus piscinarius sp. nov. is characterized by possessing a cell size of 140–210 μm, a large distinctly developed apical extrusome group, 3–4 contractile vacuoles on the ventral margin, and 6–8 left and 24–28 right kineties. Phylogenetic results based on the 18S rRNA gene data of these two species group them with other congeners, with these data suggesting the genus Amphileptus is paraphyletic. Full article
