  • Symbionts and Diseases Associated with Invasive Apple Snails
    Symbionts and diseases associated with invasive apple snails Cristina Damborenea, Francisco Brusa and Lisandro Negrete CONICET, División Zoología Invertebrados, Museo de La Plata (FCNyM-UNLP), Paseo del Bosque, 1900 La Plata, Argentina. Email: [email protected], fbrusa@ fcnym.unlp.edu.ar, [email protected] Abstract This contribution summarizes knowledge of organisms associated with apple snails, mainly Pomacea spp., either in a facultative or obligate manner, paying special attention to diseases transmitted via these snails to humans. A wide spectrum of epibionts on the shell and operculum of snails are discussed. Among them algae, ciliates, rotifers, nematodes, flatworms, oligochaetes, dipterans, bryozoans and leeches are facultative, benefitting from the provision of substrate, transport, access to food and protection. Among obligate symbionts, five turbellarian species of the genusTemnocephala are known from the branchial cavity, with T. iheringi the most common and abundant. The leech Helobdella ampullariae also spends its entire life cycle inside the branchial cavity; two copepod species and one mite are found in different sites inside the snails. Details of the nature of the relationships of these specific obligate symbionts are poorly known. Also, extensive studies of an intracellular endosymbiosis are summarized. Apple snails are the first or second hosts of several digenean species, including some bird parasites.A number of human diseases are transmitted by apple snails, angiostrongyliasis being the most important because of the potential seriousness of the disease. Additional keywords: Ampullariidae, Angiostrongylus, commensals, diseases, epibionts, parasites, Pomacea, symbiosis 73 Introduction The term “apple snail” refers to a number of species of freshwater snails belonging to the family Ampullariidae (Caenogastropoda) inhabiting tropical and subtropical regions (Hayes et al., 2015).

  • Lust Und Last Des Bezeichnens - • • Über Namen Aus Der Mikroskopischen Welt1
    © Biologiezentrum Linz/Austria; download unter www.biologiezentrum.at Denisia 13 I 17.09.2004 I 383-402 Lust und Last des Bezeichnens - • • Über Namen aus der mikroskopischen Welt1 E. AESCHT Abstract: Delight and burden of naming - About names from the microscopic world. — A short history of desi- gnating mainly genera and species of ciliates (Ciliophora), which are relatively "large" and rich of characters, is gi- ven. True vernacular (genuine) names are understandably absent; German names have been established from 1755 to 1838 and in the last three decades of the 20lh century in scientific and popular literature. A first analysis from a linguistic point of view of about 1400 scientific names of type species shows that frequently metaphoric names have been applied referring to objects of everday use and somatic characters of well known animals including human beings. A nomenclaturally updated list of 271 species including German names is provided, of which numerous syn- onyms and homonyms have to be clarified cooperatively; 160 of these species are of saprobiological relevance and 119 refer to type species of genera. Malpractices of amateurs and scientists have been due to a confusion of nomen- clature, a formalized exact tool of designation, and taxonomy, the theory and practice of classifying organisms. It is argued that names in national languages may help to publicise the diversity and importance of microscopic orga- nisms; their description and labeling are a particular challenge to creative, recently underestimated linguistic com- petence. Key words: history of nomenclature, protozoans, ciliates (Ciliophora), scientific and vernacular names, populariza- tion, taxonomy. „Nur Namen! Aber Namen sind nicht Schall und Rauch.

  • Mass Development of Periphyton Ciliates in the Coastal Zone of Southern Baikal in 2019-2020
    Limnology and Freshwater Biology 2020 (3): 433-438 DOI:10.31951/2658-3518-2020-A-3-433 Original Article Mass development of periphyton ciliates in the coastal zone of Southern Baikal in 2019-2020 Khanaev I.V.*, Obolkina L.A., Belykh O.I., Nebesnykh I.A., Sukhanova E.V., Fedotov A.P. Limnological Institute, Siberian Branch of the Russian Academy of Sciences, Ulan-Batorskaya Str., 3, Irkutsk, 664033, Russia ABSTRACT. Changes in biocenoses of the shallow water zone of open Lake Baikal continue. In the autumn of 2019 during scuba dives, we recorded abundant fouling of macrophytes in the littoral zone by ciliates of the subclass Peritrichia, the genus Vorticella, at the Listvyanka settlement – Bolshiye Koty settlement section (west coast of Southern Baikal). Despite the fact the Vorticella are the permanent component of the Bailak periphyton, such mass development of Peritrichia in the littoral zone of open Baikal has not been previously recorded. Increasing anthropogenic pressure in the littoral zone of the lake can be one of the main causes of this outbreak in the abundance of Vorticella cf. campanula, the main species of this fouling. Keywords: ciliate, Vorticella, bacteria, Lake Baikal, abundance 1. Introduction Periphyton serves as one of the important indicators of the ecological state in aquatic ecosystems The open littoral zone (i.e. the littoral zone of (Abakumov et al., 1983).

Bianca Sartini, Roberto Marchesini, Sthefane D´ávila, Marta D’Agosto, and Roberto Júnio Pedroso Dias (2018) Freshwater gastropods represent good models for the investigation of epibiotic relationships because their shells act as hard substrates, offering a range of microhabitats that peritrich ciliates can occupy. In the present study we analyzed the community composition and structure of peritrich epibionts on the basibiont freshwater gastropod Physa acuta. We also investigated the spatial distribution of these ciliates on the shells of the basibionts, assuming the premise that the shell is a topologically complex substrate. Among the 140 analyzed snails, 60.7% were colonized by peritrichs.

Here, we document four new and one unidentified species of solitary sessile peritrichs from aquaculture ponds and coastal waters of the northern Yellow Sea, China. Based on their living morphology, infraciliature and silverline system, four of the five forms were identified as new members belonging to one of three genera, Vorticella, Pseudovorticella and Scyphidia, representing two families, Vorticellidae and Scyphidiidae. The other isolate was found to be an unidentified species of the poorly known genus Paravorticella. Vorticella chiangi sp. nov. is characterized by its inverted bell-shaped zooid, short row 3 in infundibular polykinety 3 and marine habitat. Pseudovorticella liangae sp. nov. posseses a thin, broad peristomial lip and a granular pellicle.

  • Responses of Intermittent Pond Ciliate Populations and Communities to in Situ Bottom-Up and Top-Down Manipulations
    AQUATIC MICROBIAL ECOLOGY Vol. 42: 293–310, 2006 Published March 29 Aquat Microb Ecol Responses of intermittent pond ciliate populations and communities to in situ bottom-up and top-down manipulations Oksana P. Andrushchyshyn, A. Katarina Magnusson, D. Dudley Williams* Surface and Groundwater Ecology Research Group, Department of Life Sciences, University of Toronto at Scarborough, 1265 Military Trail, Ontario M1C 1A4, Canada ABSTRACT: Pond physicochemical characteristics and bottom-up effects were more important than top-down effects in governing ciliate community structure in 2 adjacent intermittent ponds in South- ern Ontario, Canada. The ciliates showed a bimodal seasonal pattern with abundances peaking early and late in the hydroperiods, and the communities showed a strong seasonal succession of species — only 15% of the 162 ciliate species were present throughout the hydroperiods. Less than half of the species occurred in both ponds. Adding riparian leaf litter to large pond enclosures affected several physicochemical variables, increased bacterial abundance, and promoted the appearance of particu- lar species — many of which are known to be associated with nutrient- or organic matter-enriched conditions. This treatment resulted in higher ciliate abundance (mainly small-sized bacterivores) and lower ciliate diversity in mid-hydroperiod in one of the ponds. The removal of plant litter generally produced effects in the physicochemical variables that were opposite to those seen in the leaf litter addition, and resulted in a 15% decrease in the proportion of ciliate bacterivores in one pond. The effects of top-down manipulations (i.e. prevention of aerial colonization of insects) were minor. Many treatment effects were season-, and pond-specific.
