2659 Corbicula fluminea Predation/Herbivory Observational Field Corbicula suppressed phytoplankton chlorophyll a. 13212
2662 Corbicula fluminea Predation/Herbivory Experimental N/A A model estimated a 70% loss of phytoplankton biomass, due to the filtration by Corbicula, and a 61% decline in annual primary production compared with a situation without Corbicula. Model simulations also showed that zooplankton may have suffered as much as a 75% loss of biomass. 33137
2663 Corbicula fluminea Predation/Herbivory Observational Field Phytoplankton decline was observed in a river, and potentially in other European and North American rivers, is not only due to Corbicula clams, but to a synergistic effect of two Dreissena species present in the river throughout the year. 33134
2667 Corbicula fluminea Predation/Herbivory Experimental Field In field studies, increasing abundance of Corbicula was negatively associated with the abundance of benthic bacteria and flagellates but had no apparent effect on other protists or meiofauna. Where large populations occur, Corbicula has potential to have a large impact on both the benthic and pelagic fauna in the many streams. 20606
2696 Corbicula fluminea Predation/Herbivory Observational Field Corbicula fluminea appears to cause localized reduction of seston concentration and may rapidly clear the sediment boundary layer of food. There was no evidence of a negative impact on the distribution of the native bivalve in spite of high measured rates of water clearance by C. fluminea. 9096
5449 Corbicula fluminea Predation/Herbivory Anecdotal N/A Modest to dramatic declines in phytoplankton or seston have been seen in heavily infested habitats - quoting (Cohen et al. 1984, Lauritsen 1986, Leff et al. 1990, Phelps 1994) North America 13063
5451 Corbicula fluminea Predation/Herbivory Anecdotal N/A dense populations of Corbicula may ingest large numbers of unionid sperm, glochidia and newly metamorphosed individuals North America 13063
5464 Corbicula fluminea Predation/Herbivory Observational Field Corbicula removed 30% of the phytoplankton chlorophyll in 2 hours Maryland, Potomac River 13212
5465 Corbicula fluminea Predation/Herbivory Observational Field Corbicula invasion was followed successively by a tripling of water clarity, resurgence of submerged aquatic vegetation, increased fish populations, and increased bird populations. Potomac River Estuary 23988
5485 Corbicula fluminea Predation/Herbivory Observational Field increased observation of ducks in the mudflats, speculation they were eating Corbicula Tennessee 12216
5486 Corbicula fluminea Predation/Herbivory Anecdotal N/A sturgeon are documented to consume Corbicula 12216
5487 Corbicula fluminea Predation/Herbivory Anecdotal N/A Notes that flatworms, including Dugesia tigrina, are known to consume young clams and were observed in large population in Kentucky Lake associated with Corbicula. Kentucky Lake 12216
5488 Corbicula fluminea Predation/Herbivory Anecdotal N/A Sheeshead drum (Aplodinotus grunniens) may benefit from consumption of Corbicula Kentucky Lake 12216
5489 Corbicula fluminea Predation/Herbivory Anecdotal N/A Common Map turtle and muskrat are noted as predators on clams that may be impacted (positive or negatively unknown) by Corbicula Kentucky Lake 12216
7378 Corbicula fluminea Predation/Herbivory Anecdotal N/A Corbicula fluminea can deplete algal abundance in large water bodies, negatively impacting native species. 42291
7379 Corbicula fluminea Predation/Herbivory Observational Field In the Meuse River in northwest Europe, the filter feeding of Corbicula fluminea caused a 70% decrease in phytoplankton abundance, thereby impacting the entire food web. Meuse River, NW Europe 42291
9536 Corbicula fluminea Predation/Herbivory Observational Field In San Francisco Baby, Acipenser transmontanus have been recorded to prey upon Corbicula fluminea. San Francisco Bay, California, USA 43005
