چکیده

Freshwater and brackish species of bryozoans belong to the Phylactolaemata and Gymnolaemata class. Twelve species of bryozoans were recorded and morphologically determined at eight locations in the Black Sea and the Adriatic basin in Croatia. Twelve species of Bryozoa have been listed in the taxonomic index for Croatia (Conopeum seurati, Lophopus crystallinus Paludicella articulata, Cristatella mucedo, Fredericella sultana, Hyalinella punctata, Plumatella casmiana, Plumatella emarginata, Plumatella fruticosa, Plumatella fungosa, Plumatella geimermassardi and Plumatella repens). For the purposes of gene identification of recorded species, molecular markers for nuclear 18S and 28S genes, ITS2 region and mitochondrial COI gene were amplified. Genetic identifications of morphologically determined bryozoan species were confirmed using highly similar sequences local alignment analysis. Proliferation of freshwater bryozoan species over long distances with the help of the vector animals was confirmed by defining haplotypes on the base of 18S, 28S and ITS2 sequences associated with the Black Sea-Mediterranean waterfowl flyway.

Bryozoans are returning home: recolonization of freshwater ecosystems inferred from phylogenetic relationships

Bryozoans are aquatic invertebrates that inhabit all types of aquatic ecosystems. They are small animals that form large colonies by asexual budding. Colonies can reach the size of several tens of centimeters, while individual units within a colony are the size of a few millimeters. Each individual within a colony works as a separate zooid and is genetically identical to each other individual w...

Freshwater biodiversity of Guam. 2. First Micronesian record of Plumatella bushnelli Wood, 2001 (Bryozoa, Phylactolaemata).

Plumatella bushnelli Wood, 2001 is the first reported freshwater bryozoan for Micronesia, and the Guam collections are only the fourth record of this species in the world. In Guam it normally occurs as small colonies on the undersides of duckweed leaves but formed larger colonies on artificial substrate.

Development and release of a malacosporean (Myxozoa) from Plumatella repens (Bryozoa: Phylactolaemata).

During an experiment to transmit Tetracapsula bryosalmonae Canning, Curry, Feist, Longshaw et Okamura, 1999 to a laboratory-cultured bryozoan, Plumatella repens L. a previously undescribed malacosporean species was noted. This parasite produced sacs of spores in the host that reached 1.2 mm in length. The spores released from the sacs appeared similar in size to the two species of Tetracapsula ...

Marine Bryozoa of Greece: an annotated checklist

BACKGROUND Until today, a complete checklist of Bryozoa of the Greek seas had never been published and species records were scattered in several taxonomic and ecological studies. The aim of this paper is to produce a first checklist of marine bryozoan species of Greece, in the framework of the Greek Taxon Information System (GTIS) initiative of the LifeWatchGreece Research Infrastructure (ESFRI...

Two new species of erect Bryozoa (Gymnolaemata: Cheilostomata) and the application of non-destructive imaging methods for quantitative taxonomy.

Two new species of cheilostome Bryozoa are described from continental-slope habitats off Mauritania, including canyon and cold-water coral (mound) habitats. Internal structures of both species were visualised and quantified using microcomputed tomographic (micro-CT) methods. Cellaria bafouri n. sp. is characterised by the arrangement of zooids in alternating longitudinal rows, a smooth cryptocy...
