“…The characteristic network of pores is found in Bithynia, Pseudobithynia (see above), Bythinella, also in Emmericia (see Appendix 2), but not in the Amnicolidae (a secondary loss?). The network occurs in Peringia (FISH & FISH 1977, FALNIOWSKI et al 1996, but is not found in the Hydrobiidae considered in the present paper. The irregular, very small pores were found in amnicolids as well as "pyrgulids".…”

are discussed and illustrated based on the literature and, where necessary, on the presented additional data. These include shell macrocharacters, protoconch sculpture, soft part morphology and pigmentation, radulae, stomach, female reproductive organs, male reproductive organs. Based on partial sequences of the ribosomal 18S RNA gene, a molecular phylogeny is presented for all the genera, and based on fragments of CO1 gene in mitochondrial DNA, for all except six genera. Based on the Adams consensus tree the two gene phylogenies are summarised and systematics of the group is proposed. Adrioinsulana is considered a junior synonym of Pseudamnicola; Parabythinella a junior synonym of Marstoniopsis; a new name: Radomaniola n. gen. is proposed as a replacement name for the preoccupied Orientalina. Litthabitella, morphologically and molecularly distinct from the hydrobioids, probably belongs to the Assimineidae. Marstoniopsis belongs to the Amnicolidae, Bythinella to Bythinellidae, Lithoglyphus to Lithoglyphidae, Heleobia to Cochliopidae, Bithynia and Parabithynia to Bithyniidae, Emmericia to Emmericiidae. Paladilhiopsis and Bythiospeum belong to the Moitessieriidae, there being no reason for homologising the two genera. All the other genera belong to the monophyletic family Hydrobiidae, within which two subfamilies can be distinguished: Hydrobiinae and Sadlerianinae. The latter includes mostly very closely related genera, which makes splitting of this subfamily into more groups of this rank unjustified. The phylogeny of the molecular characters is mapped on two molecular trees. The caecal appendix on the stomach, reduction of the basal cusps on the rhachis and the so called "spermathecal duct" evolved parallelly, and are thus homoplastic. The network of pores on the protoconch and the flagellum seem to be uniquely derived. The seminal receptacles and lobes on the penis seem to be phylogenetically old, not prone to changes and rather useful in phylogeny reconstruction. The morphologically inferred relationships of Emmericiidae and the systematic position of the two species of Parabythinella are discussed in Appendix 2 and Appendix 3, respectively. Destroyed type localities of Balkan rissooids are listed in Appendix 4.

“…The aim of this paper was to test its distinctness and phylogenetic relationships within Viviparus applying DNA markers. Some time ago the phylogeny of the other European viviparid species was reconstructed on the basis of morphological and allozymic characters (fAlniowski et al 1993a(fAlniowski et al , 1996a(fAlniowski et al , b, c, 1997(fAlniowski et al , 1998. Thus there was an opportunity to compare morphology-, allozyme-and DNAbased phylogenies.…”

were analysed. Despite slight morphological differences between the nominal species, and the near-absence of differences in nuclear 18SrRNA (18S) and histone 3 (H3) loci, mitochondrial cytochrome oxidase subunit I (COI) confirmed species distinctness of all but V. mamillatus. The latter should be synonymised with V. contectus. The comparison of COI-based phylogeny with the earlier, allozyme-and morphology-based, phylogenies suggests that V. contectus and V. viviparus are the most distantly related, in the DNA tree V. acerosus is closer to V. contectus, while in the allozyme and morphology-based tree-to V. viviparus.

“…The literature provides many examples of the increase of the number of embryos and their development advancement with the female's size (SPIGHT 1976, FALNIOWSKI et al 1996, MIDDELFART 1994, CHUNG et al 2002: the largest females carry the highest number of fully developed embryos while in the smallest females single, least developed embryos are sporadically noted. I found a similar relationship in the isolated Lake Bia³e where the mean number of embryos in the last growth stage (embryos with developed shell) increased with the female's shell height and body mass.…”

ABSTRACT. Density, sex ratio, size structure and reproduction were analysed in populations of Viviparus contectus (Millet) from oxbows differently connected with the Bug River. The mean density was 20 ind./m 2 , the sex ratio was 1:1. Snails of size classes II (8.1-12.0 mm shell width and height), III (12.1-25.0 mm width and 12.1-20.0 mm height) and IV (25.1-35.0 mm and 20.1-35.0 mm) were the most numerous. The youngest snails (shell height and width < 8 mm) were the least numerous. Smaller snails (class II) dominated in the spring. The proportion of classes III and IV increased in the summer and autumn. The number of embryos per female was the highest during the spring and summer -the period of intense reproduction. The number of embryos per female was the smallest (mean 6.8) in the oxbow isolated from the river; it was higher in the flow oxbows (13.6 and 14.2). In the isolated lake that number increased with the female's shell size. In the flow lakes the number of embryos was high irrespective of the female's size; females from these lakes showed the highest fecundity in all size classes. In the spring the mean number of embryos per female in classes II (11.5), III (12.4) and IV (14.6) was higher than in the largest females from the isolated lake. Similarly, in the summer the mean fecundity of females in class II (15.4 embryos/female) was higher than in the largest females in the lake isolated from the river (6.2).
