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 کاملThe role of the zebra mussel (Dreissena polymorpha) in structuring macroinvertebrate communities on hard substrata
We examined the importance of the Eurasian zebra mussel (Dreissena polymorpha) in structuring macroinvertebrate communities on hard substrata in the Great Lakes – St. Lawrence River system. An experiment using artificial substrata (i.e., cement bricks with either a layer of living zebra mussels, a layer of intact empty shells that mimicked living mussels, or with no added layer) showed that mac...
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 کاملModeling the Effects of Cannibalistic Behavior in Zebra Mussel (Dreissena polymorpha) Populations
The threat of invasive species has increased with the expansion of global transportation. In the United States, zebra mussels became a problem by the early 1990’s when they were introduced by ballast water into Lake St. Clair in 1988. In 2007, a new deterministic discrete-time model for zebra mussel populations was proposed by Casagrandi. We show how this model produces periodic, stable, and ch...
متن کاملStructural-based Differences in Ecotoxicity of Benzoquinoline Isomers to the Zebra Mussel (dreissena Polymorpha)
Effects of four benzoquinoline isomers on the filtration rate of the zebra mussel (Dreissena polymorpha) were analyzed, to study the effect of minor differences in chemical structure on adverse biological effects. Filtration rates were measured after 48 h of exposure to different concentrations of acridine, phenanthridine, benzo[f]quinoline, and benzo[h]quinoline in the water. The 50% effective...
