World-Wide Distribution of the Bryozoan Pectinatella Magnifica (Leidy 1851)
96 European Journal of Environmental Sciences WORLD-WIDE DISTRIBUTION OF THE BRYOZOAN PECTINATELLA MAGNIFICA (LEIDY 1851) ZUZANA BALOUNOVÁ1, EVA PECHOUŠKOVÁ1, JOSEF RAJCHARD1,*, VÍT JOZA1, and JAN ŠINKO2 1 Faculty of Agriculture, University of South Bohemia, CZ 370 05, České Budějovice, Czech Republic 2 Faculty of Fisheries and Protection of Waters, University of South Bohemia, CZ 389 01, Vodňany, Czech Republic * Corresponding author: [email protected] ABSTRACT Pectinatella magnifica (Leidy 1851) is an invasive freshwater colonial animal belonging to the phylum Bryozoa. It is native to the area east of the Mississippi River, from Ontario to Florida. Currently it occurs throughout North America and the first record for it outside that continent was for Bille near Hamburg in 1883. Later, it was found in the Elbe (Havel by Spandau), in Tegeler See, a pond in Wroclaw and in Silesia and Brandenburg. In addition, floatoblasts of P. magnifica were found in the upper Elbe in Germany in the 1950s. Then, P. magnifica spread to the area of Spandau in Berlin and the Oder, and Wroclaw. It is also recorded in Romania and Turkey. In France, it was recorded occurring in the area called Franche-Comté in 1994. Its occurrence in the Netherlands was first reported in 2003 and then each following year. The newest discoveries are for the Rhine basin in the area between Luxembourg and Germany. Recently, it was also recorded in the Czech Republic and Austria. Besides Europe and North America, it is also recorded in Japan and Korea. The statoblasts of P. magnifica are spread by flowing water, zoochory and probably also by anthropochory. -
Literature Review
2. LITERATURE REVIEW 2.1 Taxonomy of Dicrocoelium spp. The taxonomy of Dicrocoelium spp. (LA RUE, 1957) is as follows: Phylum Plathelminthes Superclass Trematoda Class Digenea Superorder Epitheliocystida Order Plagiorchiida Suborder Plagiorchiata Superfamily Plagiorchioidea Family Dicrocoeliidae Subfamily Dicrocoeliinae Genus Dicrocoelium 2.2 Species Dicrocoelium dendriticum (RUDOLPHI, 1819) is the species of Dicrocoelium with the widest distribution, found in a range from Portugal to central Asia and also in North America. D. hospes (LOOSS, 1907) is present in western, central and eastern Africa, while D. chinensis (TANG et al., 1978) is distributed in China, east Siberia and Japan. Further, D. suppereri (HINAIDY, 1983) and D. orientalis, (SUDARIKOV AND RYJIKOV, 1951) are morphologically identical with D. chinensis and are considered to be synonyms. Interestingly, D. suppereri has been recently found in a mufflon in Austria, far from localities where D. chinensis is usually reported. Possibly it was imported, and came to Europe with infected sika deer (Cervus nippon) in the 19th century. Other members of the genus Dicrocoelium are avian parasites. Dicrocoelium species differ in some morphological characteristics, geographic distribution and ecological features. 3 2.3 Morphology Dicrocoelium spp. (δικροσ: bifid; κοιλια: gut) are characterised by a lancet shaped body, with an oral and a ventral sucker. The body size is 5–10 mm in length and 2–3 mm in width, semitransparent and pied, with a black uterus and white vitellaria visible to the naked eye. The eggs are oval, dark brown, typically operculate, small (38– 45 µm x 22–30 µm), with two characteristic dark points (so called “eye spots”), and contain a miracidium (EUZÉBY, 1971). -
Taxonomic Study of Freshwater Bryozoans from Jeju Island, Korea
Journal of Species Research 6(Special Edition):129-134, 2017 Taxonomic study of freshwater bryozoans from Jeju Island, Korea Hyun Sook Chae1, Hyun Jong Kil2 and Ji Eun Seo3,* 1Department of Food-Biotechnology, Woosuk University, Jeonbuk 55338, Republic of Korea 2Animal Resources Division, National Institute of Biological Resources, Incheon 22689, Republic of Korea 3Department of Eco-Biological Science, Woosuk University, Chungbuk 27841, Republic of Korea *Correspondent: [email protected] This study aims to investigate the freshwater bryozoans of Jeju Island off the Korean Peninsula for the first time. To date, twelve species has been reported from the mainland of Korea. However, no study of freshwater bryozoans has ever been conducted on Korean islands including Jeju Island, which is the largest island in Korea. Five species in three genera Fredericella, Plumatella and Stephanella, from Jeju Island are described. Of which, three species, Fredericella indica, Plumatella mukaii and P. rugosa, are new records of Korean bryozoan fauna. As a result of this study, the number of identified Korean freshwater bryozoans is now 15 species, including 12 phylactolaemates and three gymnolaemates.

Box 56, Dunedin 9054, New Zealand; [email protected] * Correspondence: [email protected]; Tel.: +47-481-37-867 Abstract: Free-living species often receive greater conservation attention than the parasites they support, with parasite conservation often being hindered by a lack of parasite biodiversity knowl- edge. This study aimed to determine the current state of knowledge regarding parasites of the Southern Hemisphere freshwater fish family Galaxiidae, in order to identify knowledge gaps to focus future research attention. Specifically, we assessed how galaxiid–parasite knowledge differs among geographic regions in relation to research effort (i.e., number of studies or fish individuals examined, extent of tissue examination, taxonomic resolution), in addition to ecological traits known to influ- ence parasite richness. To date, ~50% of galaxiid species have been examined for parasites, though the majority of studies have focused on single parasite taxa rather than assessing the full diversity of macro- and microparasites. The highest number of parasites were observed from Argentinean galaxiids, and studies in all geographic regions were biased towards the highly abundant and most widely distributed galaxiid species, Galaxias maculatus. -

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. -

Although there are Mpumalanga province records of lymnaeid species of southern Africa based on shell morphology and controversial anatomical traits, there is paucity of information on the molecular identification and phylogenetic relationships of the different taxa. Therefore, this study aimed at identifying populations of Lymnaeidae snails from selected sites of the Okavango Delta (OKD) in Botswana, and sites located in the KwaZulu-Natal (KZN) and Mpumalanga (MP) provinces of South Africa using molecular techniques. Lymnaeidae snails were collected from 8 locations from the Okavango delta in Botswana, 9 from KZN and one from MP provinces and were identified based on phy- logenetic analysis of the internal transcribed spacer (ITS-2). -

Chibwana* and G. Nkwengulila Department of Zoology and Wildlife Conservation, University of Dar es Salaam, PO Box 35064, Dar es Salaam, Tanzania (Received 29 July 2015; Accepted 27 October 2015) Abstract The nervous systems of three Tylodelphys metacercariae (T. mashonense, Tylodelphys spp. 1 and 2) co-occurring in the cranial cavity of the catfish, Clarias gariepinus, were examined by the activity of acetylthiocholine iodide (AcThI), with the aim of better understanding the arrangement of sensillae on the body surface and the nerve trunks and commissures, for taxonomic purposes. Enzyme cytochemistry demonstrated a comparable orthogonal arrangement in the three metacercariae: the central nervous system (CNS) consisting of a pair of cerebral ganglia, from which anterior and posterior neuronal pathways arise and inter- link by cross-connectives and commissures. However, the number of transverse nerves was significantly different in the three diplostomid metacercariae: Tylodelphys sp. 1 (30), Tylodelphys sp. 2 (21) and T. mashonense (15). The observed difference in the nervous system of the three metacercariae clearly separates them into three species. These findings suggest that consistent differences in the transverse nerves of digenean metacercariae could enable the differentiation -
