	Contaminant Burdens in Sediments Colonized by Dreissena at Two Nearshore Sites in the Lower Great Lakes
		Impacts associated with the filtration of suspended particulate from the water column by prolific populations of Dreissena include increases in water transparency (Holland, 1993; Leach, 1993; Bunt et al., 1993), decreases in mean chlorophyll a concentrations (Leach, 1993) and declines in phytoplankton densities (Nicholls and Hopkins, 1993; Bunt et al.
		Dreissena can impact on the movement of contaminants through the detrital food chain to benthic invertebrates such as amphipods that are important food sources for higher trophic levels (Bruner et al.
		The potential effects of Dreissena on the accumulation of contaminants suggests that it is important to understand the effects of colonization on contaminant levels in sediments.

	Dreissena FAQs
		The genus Dreissena is highly polymorphic and prolific with high potential for rapid adaptation attributing to its rapid expansion and colonization (Mills et al., 1996).
		Other prospective approaches to controlling Dreissena populations may be to disrupt the reproductive process, by interfering with the synchronization of spawning by males and females in their release of gametes (Snyder et al., 1997).

	2.3.6 Zebra and Quagga Mussel Control Measures - Lake Source Cooling - Utilities and Energy Management - Cornell ...
		Dreissena are generally considered nuisance organisms, creating fouling problems for a variety of lake uses, including recreation, industrial withdrawals, and water supply.
		Dreissena withdrawn from the lake that settle within the LSC system will be removed from the system by periodic control measures (to be discussed in Section 2.3.6.2.2).
		Because of the rapid reproduction, growth, and spread of Dreissena in North America, much was learned in a very short period of time as to how to control mussel infestations in utilities and other industries.

	Thesis Abstract (Site not responding. Last check: )
		MOLECULAR SYSTEMATICS AND ECOLOGY OF DEEP AND SHALLOW WATER POPULATIONS OF In this study, I identified adult, post-larval and veliger larvae of Dreissena polymorpha and Dreissena bugensis, using analysis of shell morphology, and restriction analysis of the cytochrome c oxidase subunit I (COI) mitochondrial gene.
		Morphological analysis, restriction analysis and sequencing of the mitochondrial gene COI suggest that Dreissena bugensis "profunda" is a phenotype of Dreissena bugensis s.s.
		Transplanted and in-situ Dreissena polymorpha, Dreissena bugensis s.s and Dreissena bugensis "profunda" were collected from the wave zone, epilimnion and hypolimnion and analyzed for lipid concentration and gametogenic development.

		Dreissena was the overwhelmingly dominant taxon in 1991-1992.
		Dreissena may facilitate transfer of nutrients to benthic macroinvertebrates by filter-feeding on open water phytoplankton and subsequently depositing wastes on the bottom.
		The dense population of adult Dreissena in the discharge channel appears to be a "biotic sponge" which removes veligers and phytoplankton from the canal water flowing into Salmon Creek, thus depriving the creek of appropriate quality food (phytoplankton) and a source of larvae to support colonization of the creek.

		Dreissena bugensis is an introduced mussel native to the Ukraine.
		This species is impacting zooplankton abundance, biomass, and species composition causing decreases in native diversity and the extirpation of marine species.
		There is an inverse relationship between zooplankton abundance and biomass and density of Dreissena mussels, which exert pressure on zooplankton (Grigorovich and Shevtsova, 1995).

	What's in a Name When it Comes to Zebra Mussels.
		Their scientific name, Dreissena polymorpha, also refers to its shell.
		So Polymorpha means "many shapes", in reference to the fact that both the stripe pattern and shape of zebra mussels' shells can be quite different from one individual to another.
		Dreissena polymorpha is a bivalve mollusc belonging to the family Dreissenidae.

	FINAL REPORT (Site not responding. Last check: )
		Their recolonization of soft sediments of the lake bottom began at the same time when zebra mussels and quagga mussels (Dreissena spp.) were invading large areas of the sediment surface.
		That accumulations of Dreissena shells on top of the sediment reduce sediment oxygenation and thereby create less hospitable conditions for the native benthic fauna.
		This was to be done by measuring survival and growth of nymphs under layers of Dreissena shells of varied thicknesses.

	Zebra Mussel (Dreissena polymorpha) Management [Short Course]
		Zebra Mussel (Dreissena polymorpha) infestations are a significant and growing environmental concern in the Black Sea Region.
		Following the beginning of the industrial revolution, these mussels were relatively uncommon in Europe because of poor water quality; however, their densities are now increasing as environmental conditions improve.
		Recent studies in the Black Sea Region and in North America offer insight into how Zebra Mussels and other species invade new environments, the adverse impacts such invasions have on ecology and human activities, and the methods for effectively managing these impacts.

		Dreissena polymorpha must seem downright unneighborly to the residents of Monroe, Mich. In December 1989, for instance, thousands of these little mollusks, commonly known as zebra mussels, clogged the sole intake pipe of the town's water treatment plant, forcing a two-day shutdown of Monroe's schools, industries and businesses.
		In this and other cities on Lake Erie, water intake pipes provide ideal feeding grounds for the stripe-shelled biva'ves, which sift microscopic nutrients from passing water.
