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 کاملZebra Mussel ( Dreissena polymorpha ) Population Distribution In the Mohawk River System : A pilot Study
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 ...
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...
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 کاملImpacts of the zebra mussel (Dreissena polymorpha) on large lakes: influence of vertical turbulent mixing
Vertical mixing processes and thermal structure of large lakes can impact the biological processes both through vertical transport processes and the exponential decay of light with depth. I investigated the role of these issues in algal consumption, production and influence on oxygen dynamics. The impact of a benthic filter feeder limited by physical transport of algae to the benthos. Hydrodyna...
