On July 13, 1992 a team of researchers from the BFS visited Kashong Bay in order to provide a characterization of the benthic community prior to expected impacts by the then recent introduction of the zebra mussel, Dreissena polymorpha (Harman, 1993a). A transect was erected perpendicular to the shoreline from the eulittoral zone (beach) to 25 feet in depth. Inspection by SCUBA was used to coll...

1. Accumulation of organic material by the zebra mussel Dreissena polymorpha is assumed to be the source of a biodeposition-based food web. However, only little is known about the importance of the biodeposited material as a food source and its contribution to increased abundances of macroinvertebrates in the presence of D. polymorpha. 2. Feeding, assimilation and growth of the amphipods Gammar...

Bu çalışma, metabolik ve oksidatif stres biyobelirteçlerinin analizi yoluyla, su kirliliğinin iyi bir biyoindikatörü olarak kabul edilen tatlı omurgasızı Dreissena polymorpha üzerindeki Gadolinyum (Gd) toksisitesini değerlendirmeyi amaçlamaktadır. Öncelikle çalışmamızda Gd’nin D. LC50 değeri belirlenmiştir. polymorpha, kontrollü koşullar altında 24 96 saatlik süre boyunca üç letal olmayan Gd ko...

We developed and tested 14 new polymorphic microsatellite loci for dreissenid mussels, including the two species that have invaded many freshwater habitats in Eurasia and North America, where they cause serious industrial fouling damage and ecological alterations. These new loci will aid our understanding of their genetic patterns in invasive populations as well as throughout their native Ponto...

This paper concerns the detection, feature extraction and classification of behaviours of Dreissena polymorpha. A new algorithm based on wavelets and kernel methods that detects relevant events in the collected data is presented. This algorithm allows us to extract elementary events from the behaviour of a living organism. Moreover, we propose an efficient framework for automatic classification...

Dreissena polymorpha, the zebra mussel, a pestiferous mollusk from Eurasia, has spread throughout the navigable waters of the Northeastern United States since its introduction into the Great Lakes system in 1986 (Maxwell, 1992). The appearance of these organisms in the Mohawk River system was first reported in 1991 (O'Neill, 1991). By the summer of 1994 zebra mussels had successfully colonized ...

Ornamental aquaculture is one of the main sources non-native species worldwide. Unintentionally transported “hitchhiking” organisms have been previously recorded; although most these are from tropical regions, here we report on first accidental transport zebra mussel (Dreissena polymorpha) in a shipment ornamental Aegagropila linnaei (Chlorophyta) Russia to Czech Republic. This invasive listed ...

Although considerable research has been carried out on Dreissena spp., relatively little is known about the symbiotic organisms living within them. We report a two-year study of the dynamics of infection by the commensal ciliate Conchophthirus acuminatus in D. polymorpha and D. bugensis populations in the Dnieper River in the Ukraine and in four D. polymorpha populations in Belarus. C. acuminat...

In this study, some biochemical responses of Beta-Cyfluthrin (β-CF), which is a commercial insecticide in Dreissena polymorpha, were investigated. The 96 hour LC50 value β-CF on D. polymorpha was calculated as 509.62 µg L-1. exposed to subletal concentrations (1/16, 1/8 and 1/4 value: 32, 64 128 L-1) for 24 hours. Malondialdehyde (MDA) reduced glutathione (GSH) levels Acetylcholinesterase (AChE...

Bioinvasions are a major cause of biodiversity and ecosystem changes. The rapid range expansion of the invasive quagga mussel (Dreissena rostriformis bugensis) causing a dominance shift from zebra mussels (Dreissena polymorpha) to quagga mussels, may alter the risk of secondary poisoning to predators. Mussel samples were collected from various water bodies in the Netherlands, divided into size ...
