Long-term demography of a zebra mussel (Dreissena polymorpha) population
1. We used long-term data and a simulation model to investigate temporal fluctuations in zebra mussel populations, which govern the ecological and economic impacts of this pest species. 2. The size of the zebra mussel (Dreissena polymorpha) population in the Hudson River estuary fluctuated approximately 11-fold across a 13-year period, following a cycle with a 2–4 year period. 3. This cycling w...
متن کاملUsing DNA barcoding to differentiate invasive Dreissena species (Mollusca, Bivalvia)
The zebra mussel (Dreissena polymorpha) and the quagga mussel (Dreissena rostriformis bugensis) are considered as the most competitive invaders in freshwaters of Europe and North America. Although shell characteristics exist to differentiate both species, phenotypic plasticity in the genus Dreissena does not always allow a clear identification. Therefore, the need to find an accurate identifica...
متن کاملQuagga mussels Dreissena rostriformis bugensis (Andrusov, 1897) in the Main River (Germany)
The first record of the quagga mussel Dreissena rostriformis bugensis (Andrusov, 1897) in Germany is described. This species has expanded its distribution area in Europe at a slower rate than the zebra mussel Dreissena polymorpha (Pallas, 1771). Recent records from the Danube in Romania and from an enclosed Rhine-Meuse estuary in The Netherlands, suggest that the MainDanube canal and River Rhin...
متن کاملComparison of bioconcentration factors of tetrachlorobenzyltoluenes in the guppy (Poecilia reticulata) and zebra mussel (Dreissena polymorpha).
Preliminary bioconcentration factors (BCFs) were determined of six tetrachlorobenzyltoluenes (TCBTs) in guppies (Poecilia reticulata). BCFs and rate constants were derived by an iterative integration method. With this method BCFs and rate constants can be derived from experimental data of a bioconcentration test, even if the concentration in the water is not constant and steady state has not be...
متن کاملComplex interactions between the zebra mussel, Dreissena polymorpha, and the harmful phytoplankter, Microcystis aeruginosa
We report a reversal in the sign of the herbivore–phytoplankton interaction between the zebra mussel (Dreissena polymorpha) and Microcystis aeruginosa, a harmful planktonic cyanobacterium. A pair of large-scale manipulations of mussel density in the same lake in consecutive years showed that when phosphorus concentrations were very low (mean total phosphorus [TP] ; 3 mg L21), the effect of Drei...
