         一般影响

    斑马壳菜蛤可滤食7到400微米的有机与无机颗粒,与其它以浮游生物为食的物种相竞争。其后果是将原本呈悬浮态的有机物以排遗或伪排遗(pseudofeces)的形式沉淀下来,将能量与养分自浮游区转移至底栖区。改善的水质清晰度会增加水生大型植物(macrophytes)光合作用的增加,并对于喜好较混浊水域的鱼类物种(例如大眼鰤鲈)造成负面影响。移除绿色藻类会为蓝绿藻带来竞争优势,因为在蓝绿藻存在时斑马壳菜蛤会停止滤食行为。斑马壳菜蛤会成群栖息在原生壳菜蛤之上(Unionidaceae),造成后者的空气与养分缺乏,最后因能量紧迫而死。斑马壳菜蛤栖息之处,原生壳菜蛤的数量都急遽下降,尤其在五大湖区、哈德逊河以及密西西比河一带。牠们在坚硬基质上的高密度栖息对底栖无脊椎动物是有利的,因为栖息复杂性增加,且可得的有机物也增加了。鱼类(例如灰鳟鱼)的繁殖礁脉亦遭受斑马壳菜蛤栖息的不利影响。

    Denmark English 
    生态系统变化: Dreissena consumes a lot of plankton in the water. In Lake Esrom, Denmark, 18% of the phytoplankton production was consumed by D. polymorpha (Hamburger et al. 1990, in Birnbaum 2006). This decrease in plankton may cause a decline in the populations of some fish species (Birnbaum 2006).

    Lake St. Clair (North America) English 
    降低本地生物多样性: The introduction of Dreissena polymorpha in 1988 resulted in the extirpation of native mussels in most of Lake St. Clair by 1991. However, communities of native bivalves have continued to survive in refuge sites in various near-shore areas of the lake. Surveys from 1998-2001 found 22 species of native unionids at 33 sites giving hope for their preservation (Hunter & Simons, 2004; Schloesser et al, 1996; Zanetta et al, 2002).
    Lake Erie (North America) English 
    改变营养机制: Results of a study (Conroy et al. 2005) which primarily tested for differences in ammonia-nitrogen and phosphate-phosphorus excretion rates of D. polymorpha and D. bugensis the two invasive molluscs in Lake Erie, and also compared dreissenid ammonia and phosphate excretion with that of the crustacean zooplankton, demonstrated that mussels add to nitrogen and phosphorus remineralisation, shortening nitrogen and phosphorus turnover times, resulting in the modification of the nitrogen and phosphorus cycles in Lake Erie. The authors conclude that this increased nutrient flux may facilitate phytoplankton growth and cyanobacterial blooms in well-mixed and/or shallow areas of western Lake Erie. There have been reports of recent increases in phytoplankton biomass and the recurrence of cyanobacterial blooms in western Lake Erie.

    生态系统变化: Dreissena polymorpha is believed to have caused an increase in non-burrowing amphipods in Lake Erie due to increased habitat complexity that results from zebra mussel cover of substrate, possibly by reducing predation risk (Gonzalez & Downing, 1999).

    竞争: Dreissena polymorpha competes with and fouls native bivalves in Lake Erie. The burrowing amphipod Diporeia hoyi declined from 38 to 1.8% of the total benthic biomass from 1979 to 1993 since the introduction of D. polymorpha, and its density declined from 1840×m2 in 1979 to 220×m2 in 1993 (Bially & MacIsaac, 2000; Dermott & Kerec, 1997).
    Lake Michigan (North America) English 
    降低本地生物多样性: Dreissena polymorpha has resulted in significant reduction in fingernail clams (Sphaeriidae spp.) in Lake Michigan. A study from 1992-1997 found that approximately half of the fingernail clams shells between I and 2 mm in size were used as substrate for attachment by juvenile and adult zebra mussels, while over 90% of the clams > 2 mm showed attachment by zebra mussels. Overall median densities of Sphaeriidae decreased from 832/m² to 13/m² at the 15 m depth and from 234/m² to 0/m² at the 10 m depth during the study. It appears that zebra mussel colonization caused a dramatic reduction of Sphaeriidae density by 1997 that may eventually result in their loss from the area (Lauer & McComish, 2001).
    The decline in native amphipod Diporeia spp. occurred progressively from shallow to deep regions, and was temporally coincident with the expansion of Dreissena polymorpha (Nalepa et al, 2009).
    Lake Ontario (North America) English 
    改变自然底栖生物群落: The establishment of Dreissena polymorpha and D. bugensis coincided with a drastic decline of native amphipod Diporeia spp. (Owens & Dittman, 2003).

    降低本地生物多样性: In response to the disappearance of Diporeia spp., believed to have resulted from the introduction of Dreissena polymorpha and D. bugensis, populations of two native benthivores, slimy sculpin and lake whitefish, collapsed in eastern Lake Ontario, perhaps due in part to starvation, because Diporeia was their principal prey (Owens & Dittman, 2003).
    St. Lawrence River (North America) English 
    改变自然底栖生物群落: Dreissena polymorpha colonization alters macroinvertebrate communities on hard substrata by enhancing conditions for deposit-feeding organisms, small gastropods, and small predatory invertebrates, and by displacing large gastropods and certain large filterers. In the St. Lawrence River, these effects were associated with zebra mussel densities of 1500–4000 individuals/m2 (Ricciardi et al, 1997)

    污染: Locations of St. Lawrence River where Dreissena polymorpha occurred in densities of 4,000-20,000/m2 resulted in 90-100% native unionid mortality. D. polymorpha colonize unionids bivalves in high densities. Data suggests that once Dreissena mass is equal to or exceeds that of the bivalve, it will be extirpated (Ricciardi et al, 1996).
    Poland English 
    污染: Presents a problem in that it fouls ships, barges and other water vessels (DAISIE 2006).

    竞争: Competitive effects on other species due to the zebra mussel have been recorded in Estonia (NOBANIS 2009; DAISIE 2006).
    Russian Federation English 
    经济 /民生: Socio-economic impacts due to the zebra mussel have been recorded in Russia (NOBANIS 2009)
    Turkey English 
    污染: Fouling problems caused by the Driessena polymorpha were observed in Kovada I Hydroelectric Power Plant (HEPP) situated in the south western Mediterranean region of Turkey in 1964 (Bobat et al, 2004).
    England (United Kingdom (UK)) English 
    生态系统变化: A fishing lake in Lancashire has experienced increased water clarity and reduced fish biomass coincidental with the arrival of Dreissena polymorpha (Aldridge, 2004).

    经济 /民生: Dreissena polymorpha has resulted in many water treatment works experiencing blockage of microstrainers and pumps, the occlusion of pipes, and the compromising of filter bed efficiency in Britain (Aldridge et al, 2006).

    降低本地生物多样性: A newly recorded population of Dreissena polymorpha in Barden Lake, Kent, appears to be having a deleterious impact on native unionid mussels, particularly the swan mussel (Anodonta cygnea) and, more, recently the painters mussel (Unio pictorum) (Aldridge et al, 2004).
    Northern Ireland (United Kingdom (UK)) English 
    改变自然底栖生物群落: The invasion of Dreissena polymorpha resulted in an increase of zooplankton in Lough Erne (Maguire et al, 2006).
    Great Lakes (USA) (United States (USA)) English 
    威胁濒危物种: Dreissina polymorpha competes with and threatens 11 species of endangered freshwater molluscs in the Great Lakes Basin of Canada and the United States (Alan et al, 2006).

    竞争: Since the introduction of Driessena polymorpha and Driessena bugensis Diporeia hoyi has declined in all Great lakes except Lak Superior (Dermott et al, 2005).
    Hudson River (United States (USA)) English 
    改变自然底栖生物群落: The invasion of Dreissena polymorpha resulted in an 85% decrease of phytoplanktron in the Hudson River. However, bacterial abundances in the Hudson have increased roughly two times since the D. polymorpha arrived, making it clear that direct consumption by Dreissena is a minor process, but they do dramatically reduced flagellated protozoans, the major predator of bacteria. Another study found a 778- fold decrease in cyanobacteria and a 2.5- times fold decrease in diatoms in the Hudson River after the introduction of D. polymorpha. (Caraco et al., 1997; Findlay et al., 1998; Smith et al., 1998).

    生态系统变化: After the introduction of Dreissena polymorpha studies found that the median decrease in abundance of open-water species was 28%, whereas the median increase in abundance of littoral species was 97%. Populations of open-water species shifted downriver away from the zebra mussel population, whereas those of littoral species shifted upriver. Median apparent growth rates fell by 17% among openwater species and rose by 12% in the single littoral species studied. Researchers found that the influence of zebra mussels on fish should vary widely across ecosystems as a function of system morphology, factors that limit primary production, and diets of the fish species (Strayer et al, 2005).

    降低本地生物多样性: Native bivalves of the Hudson experienced a 65-100% decline in the Hudson River after the introduction of Dreissena polymorpha. By 2000, their populations seemed to level off and are believed to remain at 4-22% of preinvasion densities (Strayer & Malcom, 2007).
    Illinois (United States (USA)) English 
    降低本地生物多样性: Significant declines of native mussels have occurred in Illinois rivers as a result of the establishement of Dreissena polymorpha (Ricciardi et al, 1998).
    Michigan (United States (USA)) English 
    降低本地生物多样性: A sampling of the Detroit River in 1982-1983 before the introduction of Dreissena polymorpha and Dreissena bugensis resulted in 97% live unionids of 20 different species, whereas a sampling in 1992 after the introduction of the two Dreissena spp. resulted in only 10% live unionids of only 13 different species. Surveys of native freshwater mussels along main channels of the Detroit River from 1992-1994 showed that unionids had been extirpated from all but four sites in the upper reaches of the river due to impacts of dreissenid mussels (Schloesser et al, 1998; Schloesser et al, 2006).
    Mississippi River (United States (USA)) English 
    威胁濒危物种: Over 60 endemic mussel species are threatened with extinction by impacts from Dreissena polymorpha. Specifically it threatens federally-endangered Higgins eye pearlymussel (Lampsilis higginsii) (Ricciardi et al, 1998; Wege, 2005).
    New York (United States (USA)) English 
    生态系统变化: Researchers report a significant increase in water clarity of Oneida Lake, New York as a result of the introduction of Dreissena polymorpha. Its filtration of particles in the water column increases water clarity, allowing deeper light penetration which in turn enhances benthic photosynthesis (Zhu et al, 2006).
    Ohio (United States (USA)) English 
    生态系统变化: Colonization of Dreissena polymorpha population in Hargus Lake, a small thermally stratified reservoir in Ohio, US., caused a significant increase in water clarity and a remarkable decrease in phytoplankton biomass during the period from 1993 to 1995. Increased light penetration and reduced organic matter loading to the meta-and hypolimnion were reflected in the lake stratification patterns, particularly in the temperature and oxygen profiles in the metalimnion (Yu & Culver, 2000).

    降低本地生物多样性: Significant declines of native mussels have occurred in Ohio rivers as a result of the establishment of Dreissena polymorpha (Ricciardi et al., 1998).
    Pennsylvania (United States (USA)) English 
    污染: Dreissena polymorpha fouls native unionid mussels in these lakes (Butkas & Ostrofsky, 2006).
