Diversity of Echinostomes (Digenea: Echinostomatidae) in Their Snail Hosts at High Latitudes
Parasite 28, 59 (2021) Ó C. Pantoja et al., published by EDP Sciences, 2021 https://doi.org/10.1051/parasite/2021054 urn:lsid:zoobank.org:pub:9816A6C3-D479-4E1D-9880-2A7E1DBD2097 Available online at: www.parasite-journal.org RESEARCH ARTICLE OPEN ACCESS Diversity of echinostomes (Digenea: Echinostomatidae) in their snail hosts at high latitudes Camila Pantoja1,2, Anna Faltýnková1,* , Katie O’Dwyer3, Damien Jouet4, Karl Skírnisson5, and Olena Kudlai1,2 1 Institute of Parasitology, Biology Centre of the Czech Academy of Sciences, Branišovská 31, 370 05 České Budějovice, Czech Republic 2 Institute of Ecology, Nature Research Centre, Akademijos 2, 08412 Vilnius, Lithuania 3 Marine and Freshwater Research Centre, Galway-Mayo Institute of Technology, H91 T8NW, Galway, Ireland 4 BioSpecT EA7506, Faculty of Pharmacy, University of Reims Champagne-Ardenne, 51 rue Cognacq-Jay, 51096 Reims Cedex, France 5 Laboratory of Parasitology, Institute for Experimental Pathology, Keldur, University of Iceland, IS-112 Reykjavík, Iceland Received 26 April 2021, Accepted 24 June 2021, Published online 28 July 2021 Abstract – The biodiversity of freshwater ecosystems globally still leaves much to be discovered, not least in the trematode parasite fauna they support. Echinostome trematode parasites have complex, multiple-host life-cycles, often involving migratory bird definitive hosts, thus leading to widespread distributions. Here, we examined the echinostome diversity in freshwater ecosystems at high latitude locations in Iceland, Finland, Ireland and Alaska (USA). We report 14 echinostome species identified morphologically and molecularly from analyses of nad1 and 28S rDNA sequence data. We found echinostomes parasitising snails of 11 species from the families Lymnaeidae, Planorbidae, Physidae and Valvatidae. -

The aim of the present study was to investigate the prevalence of the genus Bilharziella in comparison to other bird schistosome species from Lake Drawsko À one of the largest recreational lakes in Poland, struggling with the huge problem of swimmer’s itch. In total, 317 specimens of pulmonate snails were collected and examined. The overall digenean infection was 35.33%. The highest bird schistosome prevalence was observed for Bilharziella sp. (4.63%) in Planorbarius corneus, followed by Trichobilharzia szidati (3.23%) in Lymnaea stagnalis and Trichobilharzia sp. (1.3%) in Stagnicola palustris. The location of Bilharziella sp. -

Habitat-Specific Preferences of a Malacophagous Leech for Freshwater Snails As Prey
European Journal of Ecology, 6.1, 2020, pp. 121-136 CHOOSING EXOTIC OVER THE FAMILIAR TASTE: HABITAT-SPECIFIC PREFERENCES OF A MALACOPHAGOUS LEECH FOR FRESHWATER SNAILS AS PREY Pranesh Paul, Rupsha Karmakar, Gautam Aditya* Department of Zoology, University of Calcutta, 35, Ballygunge Circular Road, Kolkata – 700019 Abstract. The spread of freshwater invasive species through aquarium trade poses a threat to the ecosystem, economy and human health. The availability of the exotic freshwater gastropod mollusc, Planorbarius corneus (Linnaeus, 1758) (Gastropoda: Planorbidae), in pet shops in Kolkata, West Bengal, India, raises concern for its potential establishment as an invasive species. Assuming the role of the native predators as a potential biotic barrier for invasion, observations on the predation pattern of the malacophagous leech, Glossiphonia weberi (Blanchard, 1897) (Clitellata: Glossiphoniidae) against P. corneus was made in single as well as in combination with the native snail Indoplanorbis exustus (Deshayes, 1834) (Gastropoda: Planorbidae). Using varying size classes and densities of P. corneus, the predation potential of G. weberi was estimated after a 24 hour period. In another set of experiments, the predation of G. weberi against the snail P. corneus was observed in the presence of I. exustus under four different habitat conditions. The purpose was to justify - (1) the effect of conspecific and het- erospecific conditions of the prey availability and (2) the effect of habitat complexity on the predatory efficacy of G. weberi. The results indicated that G. weberi consumed varied numbers of P. corneus, depending on the size and the densities of the prey and predator. Although the prey heterogeneity and complex habitats caused significant reduction of predation on both of the prey species, G. -

A Primer to Freshwater Gastropod Identification
Freshwater Mollusk Conservation Society Freshwater Gastropod Identification Workshop “Showing your Shells” A Primer to Freshwater Gastropod Identification Editors Kathryn E. Perez, Stephanie A. Clark and Charles Lydeard University of Alabama, Tuscaloosa, Alabama 15-18 March 2004 Acknowledgments We must begin by acknowledging Dr. Jack Burch of the Museum of Zoology, University of Michigan. The vast majority of the information contained within this workbook is directly attributed to his extraordinary contributions in malacology spanning nearly a half century. His exceptional breadth of knowledge of mollusks has enabled him to synthesize and provide priceless volumes of not only freshwater, but terrestrial mollusks, as well. A feat few, if any malacologist could accomplish today. Dr. Burch is also very generous with his time and work.

It includes 39 species from 170 species found in Latvia. The category 0 has no species, there is 1 species in the first category, 6 species in the second category, 25 species in the third category, and 7 species in the fourth category. Evaluation criteria similar to these in the previously published Red Books have been used. Information on 64 species included in the IUCN LC category is also collected. There is no need for special protection measures for these species; however, the dynamics of their populations should be monitored. Key words: Latvia, mollusc species, protection status. Introduction Red List categories The first Red Data Book of Latvia was published 33 years The definitions of the following categories are based on ago (Aigare et al. -

Mitotic and Meiotic Chromosomes of the Great Ramshorn Snail Planorbarius Corneus (Linnaeus, 1758) (Gastropoda, Planorbidae) from Lake Kortowskie
POLISH JOURNAL OF NATURAL SCIENCES Abbrev.: Pol. J. Natur. Sc., Vol 30(1): 47–57, Y. 2015 MITOTIC AND MEIOTIC CHROMOSOMES OF THE GREAT RAMSHORN SNAIL PLANORBARIUS CORNEUS (LINNAEUS, 1758) (GASTROPODA, PLANORBIDAE) FROM LAKE KORTOWSKIE Aleksandra Szabelska, Dorota Juchno, Aneta Spóz, Alicja Boroń Department of Zoology, Faculty of Biology and Biotechnology University of Warmia and Mazury in Olsztyn, Poland K e y w o r d s: cytogenetics, molluscs, Planorbidae, chromosomes, spermatozoa. Abstract An analysis of meiotic and mitotic chromosomes of P. corneus inhabiting Lake Kortowskie was made in order to verify the use of different tissues and colchicine treatments, the hypotonization time and two methods of chromosome slide preparation. In total, 30 chromosomal slides of six individuals were analyzed. The well spread chromosomes were introduced onto the slides by dropping a cell suspension of the mantle epithelium, foot and intestine of each individual, directly injected with colchicine, after 20 min of hypotonization. The karyotype was composed of 2n=36 biarmed chromo- somes, thirty metacentrics with the rest being submetacentrics, NF=72. In the slides of the gonads the meiotic chromosomes in spermatogenesis were observed as being in prophase I (leptoten, zygoten, and diakinesis) and in telophase I. In diakinesis 18 bivalents were formed. No disturbances were observed during meiosis. The spermatozoa were typical of aquatic molluscs; consisting of a spherical head, a short midpiece and a long tail.
