Abundance of Dreissena polymorpha and Dreissena bugensis in a warmwater plume: effects of depth and temperature
The generalization that quagga mussel (Dreissena bugensis) and zebra mussel (Dreissena polymorpha) occur in deepcold water and shallowwarm water, respectively, is inappropriate. We estimated dreissenid densities at sites affected by warmwater discharges into Lake Erie (Nanticoke, Ontario) to separate the effects of depth and temperature. Both species densities increased with depth. After con...
متن کاملSeasonal Dynamics of Conchophthirus acuminatus ( Ciliophora , Conchophthiridae ) Infection in Dreissena polymorpha and D . bugensis ( Bivalvia , Dreissenidae )
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...

متن کاملAbundance and size of quagga mussels (Dreissena bugensis) veligers in Lake Mead, Nevada-Arizona
The planktonic veligers of the invasive quagga mussel were present year-round from April 2008 to March 2009 in Lake Mead, with high abundance from September to October (>20 veligers/L), whereas the percentage of competent veligers, in terms of the ability to settle, peaked fromNovember 2008 to January 2009 (>60%). The results from this experiment are useful in understanding the life history and...
متن کاملInfluence of physicochemical factors on the distribution and biomass of invasive mussels (Dreissena polymorpha and Dreissena bugensis) in the St. Lawrence River
Twenty sites along the St. Lawrence River were sampled to determine if the distribution and abundance of invasive mussels (zebra mussel (Dreissena polymorpha) and quagga mussel (Dreissena bugensis)) are explained by physicochemical variables. Calcium concentration, substrate size, and depth independently explained significant proportions of variation in biomass for both species. Zebra mussel po...
