Classical and Molecular Cytogenetic Characterization of Allochthonous European Bitterling Rhodeus Amarus (Cyprinidae, Acheilognathinae) from Northern Italy
Genes Genet. Syst. (2008) 83, p. 417–422 Classical and molecular cytogenetic characterization of allochthonous European bitterling Rhodeus amarus (Cyprinidae, Acheilognathinae) from Northern Italy Angelo Libertini1, Luciana Sola2*, Massimiliano Rampin1, Anna Rita Rossi2, Koji Iijima3 and Takayoshi Ueda3 1Institute of Marine Sciences, National Council for Research, Castello 1364/a, Venice 30122, Italy 2Department of Animal and Human Biology, “La Sapienza” Rome University, Via A. Borelli 50, Rome 00161, Italy 3Department of Biology, Faculty of Education, Utsunomiya University, 350 Mine, Utsunomiya 321-8505, Japan (Received 23 July 2008, accepted 10 September 2008) A cytogenetical study was carried out on 34 specimens of the European bitter- ling Rhodeus amarus (Teleostei: Cyprinidae, Acheilognathinae) from four rivers of the Venice district (NE Italy). This allochthonous fish species was accidentally introduced in the North-East of Italy about 20 years ago and is now rapidly spreading all over the rivers of the Northern part of the country. All the studied specimens are characterised by the same karyotype (2n = 48: 8M + 20SM + 20ST), i.e., the typical one of the native populations of the species. However, a polymor- phism in the number of NOR bearing chromosomes has been found. In fact, in addition to the main species-specific NORs, on the short arms of chromosome pair 7, two to five additional 18S rDNA sites have been revealed by FISH in different specimens. Sequential staining with silver nitrate, chromomycin A3 and DAPI revealed that most of the additional sites are inactive and CMA3-positive. Data herein reported confirm that in spite of an overall morphological karyo- logical conservativeness, significant differences for the finer cytogenetic features can be found within the Acheilognathinae with the 2n = 48 and NF = 76 karyotype. -
Crayfish As Trophic Agents: Effect of Austropotamobius Torrentium On

Due to their size, behaviour and feeding activity they may invertebrate, affect structure and function of aquatic ecosystems and their organisms. ecosystem Despite their importance in many freshwaters and available information on engineer, their ecology for several species little is known about the European cray- headwaters, fish Austropotamobius torrentium. In order to evaluate the potential effects aquatic of indigenous crayfish presence on the structural and functional compo- insects, sition of the zoobenthic community, we measured population size and functional densities of three A. torrentium populations and compared macroinver- feeding guilds tebrate assemblages and physicochemical parameters in three streams with and three without crayfish. The experimental setup considered cray- fish effects at a large scale in defined reaches of pristine headwaters in as- sociation with the whole benthic fauna under natural conditions. Presence of A. torrentium significantly affected zoobenthic abundance, diversity and the relative proportions of functional feeding groups. In crayfish streams, especially Trichoptera and collector gatherers were more abundant and di- verse, while sites without crayfish had significantly higher abundances and diversities of shredders and wood feeders. Our study provided strong ev- idence that the presence of the indigenous crayfish A. -

We used morphological and genetic data to resolve the taxonomic relationships of bitterling in Europe. Previous studies have suggested the European bitterling is either a single species with a wide but discontinuous geographic distribution, or a complex of species. Morphometric and meristic data identified differ- ences between three putative species; with a clear distinction between the eastern Asian Rhodeus sericeus, western European bitterling Rhodeus amarus, and colchian bitterling, Rhodeus colchicus. Polymorphism in the mitochon- drial DNA control region was predominantly due to insertion/deletion events, making phylogenetic inference difficult, but the single haplotype found in R. sericeus populations was detected at low frequency (one of 24 individuals) in R. amarus and R. colchicus populations. Eight control region haplotypes were found in R. amarus populations, which were distinct from the two haplotypes in a R. colchicus population. Cytochrome b data produced a phylogeny with strongly-supported differentiation between a clade of two R. -

Bogutskaya*, A. M. Komlev** *Zoological Institute, Russian Academy of Sciences Universitetskaya nab., 1, St. Petersburg, 199034, Russia **St. Petersburg State University Universitetskaya nab., 7, St. Petersburg, 199034, Russia Rhodeus sericeus is revised with a use of new characters – cephalic sensory canal pattern, configuration of infraorbitals, and vertebral structure along with some traditional ones. No characters were found which clearly confirm the specific status of R. sericeus amarus. Rhodeus colchicus, new species, is described from the rivers in West Transcaucasia, Georgia. It is distinguished from congeners by a suite of characters which includes large scales (34 to 37, commonly 35, in the lateral row), a low number of vertebrae (33 to 36, commonly 35, total, and 16 to 18, commonly 17, in the abdominal region), a deep shortened 2nd infraorbital, a broad 4th infraorbital and a well developed 5th one with a widened lamellate portion. Introduction The Amur common bitterling was described as Cyprinus sericeus by Pallas (1776) from River Onon (Upper Amur system) and the European bitterling, Cyprinus amarus, some years later by Bloch (1782) from River Elbe. They were considered to be close or conspecific by many authors, for example, Dybowski (1869, 1877) and Warpachowski (1887). The study by Svetovidov and Eremeyev (1935) showed that European and Asian bitterlings are slightly different in some characters and proposed to give them a rank of subspecies of one and the same species. -
Austropotamobius Torrentium As an Indicator for Habitat Quality in Running Waters?

E-mail: [email protected] Reçu le 9 novembre 2004 Received November 9, 2004 Accepté le 4 janvier 2005 Accepted January 4, 2005 ABSTRACT In the present study we tried to quantify the indication value of A. torrentium referring to habitat quality. This variable is expressed as the availability of appropriate refuge stones on the bottom and banks of running waters. The brooks occupied by the indigenous stone crayfish in Lower Austria show a high variability in the current velocity and substrate heterogeneity. Having some experience in hand searching we assumed that the distribution pattern of the crayfish on the stream bed is strongly correlated with the distribution of cobble and pebbles within a certain grain size. The aim of our study was to quantify the dependence of the shelter requirements for A. torrentium on grain size and water velocity, as well as the seasonal mobility of the crayfish. Shelters where velocity exceeded 25 cm s-1 were not occupied. Pebbles with a bearing surface greater than 300 cm2 were preferred, and the probability of crayfish occupation rose quickly as the stone’s bearing surface increased up to 900 cm2. -
