Scherwass, A. and H. Arndt. 2005. Structure, dynamics and control of the ciliate fauna in the potamoplankton of the River Rhine. Archiv für Hydrobiologie 164 (3):287-307.
Planktonic ciliate abundance and taxonomic composition were investigated from November 1998 to January 2000 in the River Rhine at Cologne, Germany. The composition of the ciliate fauna revealed the occurrence of both typical benthic (drifting peritrichs) as well as pelagic ciliates (oligotrichs) in the potamoplankton. Oligotrich ciliates prevailed in the potamoplankton community. Peritrichs, represented almost exclusively by sessile species, appeared to be washed out from the substrate at increased water discharge during flood events. Highest abundances of ciliates were registered during the phytoplankton spring bloom, indicating a bottom-up control of ciliates during this time, an observation which was supported by laboratory experiments. In summary, the ciliate potamoplankton community of the River Rhine is controlled by a seasonally varying set of factors: 1) Flood events in early spring and autumn cause a short-term succession from drifting peritrichs to pelagic oligotrichs, 2) the phytoplankton spring bloom supports oligotrich population growth, and 3) the low water level and subsequently high grazing pressure by benthic predators (mainly the mussel Corbicula) reduce the abundance of ciliates. The latter was probably the major reason for the extremely low ciliate abundances observed during summer.

Freshwater mussels (naiads) were collected from the Kanawha River, West Virginia, at several locations between Winfield and Falls View as part of a statewide survey to identify naiad populations. Sampling took place during the Fall of 1981 and the Fall of 1982 when the river was low and clear. Naiad populations were sampled with a 10-foot dovetail mussel brail and sight/hand collecting. Nineteen species of naiads and the asiatic clam Corbicula sp. were collected. The majority (18 species) were collected in the seven-mile stretch of the Kanawha River downstream of Kanawha Falls. Two species - Cyprogenia stegaria and Obliquaria reflexa are very rare in West Virginia. Only Corbicula sp. and one naiad species, Anodonta g. grandis, were collected downstream of Charleston. No endangered species were collected, although a population of Lampsilis abrupta (= orbiculata) is known to occur downstream of Kanawha Falls near Deepwater.

To date, ten major streams and three river basins within West Virginia have been investigated for freshwater mussel (naiad) populations. Three additional streams have been investigated, but no living naiads have been collected. Sampling has been ongoing since mid-1980, and sampling techniques have included bank collection, water scopes, snorkeling and brailing. A total of 48 naiad species plus the Asiatic clam (Corbicula sp.) have been collected thus far.

The variety of Melanopsis acicularis F'erussac occurring in the Eger region of Hungary dates from the lower Pleistocene and occurs in powdery limestone layers which must formerly have been in a warm climate. Varieties of this mollusc of smaller size probably occurred in colder water. The evolution of this species in Eger is discussed. Some related species are newly described and all were found at Zarkandy in the Eger at lower levels than those in which M. acicularis was found. These species have also been found in Budd Kalasz (a suburb of Budapest), Dorog, and Tolnamozs, Hungary. At Vecsey, East Germany, many of the same species were collected in calcareous limestone together with Corbicula fluminalis, which is widely distributed.

Scott Wasilk, J., G. G. Downing and J. S. Lietzow. 1983. Occurrence of the Asiatic clam, Corbicula fluminea in the Maumee River and western Lake Erie. Journal of Great Lakes Research 9(1):9 13.
Corbicula fluminea was found in only two locations along the southern shore of the western basin of Lake Erie: the thermal plume areas of two coal fired power plants with once through condenser cooling systems. Three sewage treatment plant outfalls were sampled, but C. fluminea were found only in the sewage treatment plant outfall that was within the thermal plume of a power plant. No C. fluminea were found in the vicinity of the nuclear power plant which has a closed cycle natural draft cooling tower, and hence, no significant thermal plume.
From the age of some of the specimens, this clam has probably resided in the region since 1978. The Great Lakes are farther north than the natural range of this clam, and prolonged cold temperatures in this region may be responsible for the confinement of this clam to baseload power plants with continuous thermal plumes.

In 1981 and 1982, the thermal plume areas of four power plants along the southern shore of Lake Erie were sampled for Corbicula fluminea. C. fluminea were found in only two of those four locations: the thermal plumes of the Toledo Edison Acme and Bay Shore Generating Stations. Both power plants are coal fired with once through condenser cooling systems. Acme is located in Toledo on the Maumee River. Bay Shore is located east of Toledo on the southern shore of Maumee Bay.
The two power plants at which no Corbicula fluminea were found are the Toledo Edison Davis Besse Nuclear Power Station located near the mouth of the Toussaint River and the Cleveland Electric Illuminating Company Eastlake Power Plant on the Central Basin east of Cleveland. Davis Besse has a closed cycle natural draft cooling tower, and hence no significant thermal plume. Eastlake has a once through condenser cooling system and a large thermal plume.
In 1982, specimen length varied from 4 mm to 35 mm. The majority of the specimens were collected from the Bay Shore thermal plume. The substrata in which the clams were found were predominantly clay and muck. In 1981 and 1982 findings were consistent in indicating that Corbicula fluminea has not spread beyond the confines of the thermal plumes of the Acme and Bay Shore generating stations.

Asian clam Corbicula fluminea, the amphipod Dikerogammarus villosus and the macrophyte Nuphar lutea were tested for investigating spatial and temporal variability in the bioavailability of tin and arsenic in the River Lippe, Germany. Samples were collected from September 2002 to May 2003 at a tin polluted site (source pollution) and a reference site. Additional screening sampling was carried out twice in April 2003 to test the extent of As and Sn concentration in periphyton (aufwuchs) samples. Accumulated Sn and As concentrations were measured with ICP-MS after sample processing (dissection, cryo-milling) and digestion. Quality control was performed by parallel analysis of three certified reference materials. Measurable As and Sn contents in plant tissues were only detectable in roots (below 30 microg kg(-1) and 20 microg kg(-1) for As and Sn, respectively). Homogenates from C. fluminea and D. villosus tissues showed site-dependent trace metal contents. Elevated bioavailability of Sn is present downstream of the sewage discharge of the world's biggest producer of tributyltin (TBT) at Luenen (northern Ruhr region). In comparison to C. fluminea, D. villosus shows higher concentrations of tin in samples from both sites. Arsenic concentrations in C. fluminea remain constant with increasing shell size, whereas tin shows a size-dependent accumulation. The results indicate that Corbicula fluminea and Dikerogammarus villosus are suitable passive biomonitoring organisms for Sn, but As levels might be actively regulated. The concentration of tin in the periphyton (aufwuchs) samples was found to be much higher in samples from a contaminated site (428 ± 63 vs. 1949 ± 226 μg kg-1).

The most important food item by far for Graptemys pulchra is Corbicula manilensis. This clam probably represents the predominant macrozoic biomass in the study area (Escambia River). It was so abundant in some bottom situations that a sample of the top 3 cm of substratum often yielded equal volumes of C. manilensis and sand. During some periods of rapidly dropping water level, shells were deposited on sandbars in concentrations of several hundred per square meter. C. manilensis represented at least 95% of all food consumed by adult female G. pulchra. Some correlation was found between carapace length and size of C. manilensis eaten. Individuals under 150 mm CL fed mostly on clams from 2 to 12 mm in length, while individuals over 150 mm CL fed on all sizes, particularly those from 5 to 20 mm in length. Adult females (over 220 mm CL) fed mostly on clams from 15 to 25 mm long. The largest C. manilensis specimen consumed was 30 mm long. Small numbers of minute C. manilensis shells were frequently found in male fecal samples, but did not constitute an important item. Some individuals in their first few seasons of growth contained highly eroded fragments of large C. manilensis shells, much larger than could possibly have been crushed by turtles of such small size. This, combined with the facts that only incomplete shells were found, and that fragments were not greatly eroded by a single passage through the digestive tract of large individuals, led to the conclusion that fragments expelled by large individuals were ingested by small turtles. The reason for this cannot be determined, but it may be related to the obtainment of calcium salts for shell development or other needs.

The investigation showed that natural phenomena (e.g., flooding) and the opportunistic methods of locomotion (e.g., mucous "drogue" excretion) provide Corbicula with a means to recolonize areas greater than 20 miles downstream. Both the May and September collections (141 samples) revealed only 59 clams in the Ohio River study area. However, concurrent with the river flooding during November, Bay D had a dramatic infestation (an estimated 1,350,000) of clams in only 4 weeks. It is highly unlikely that such a large population of Corbicula would have been missed in the May and September collections had they inhabited the study area.
It is significant to note that the unusually high numbers of Corbicula collected in the intake bays considering the following factors. First, the physical positioning of the intake structure is parallel to the shoreline, designed to reduce funneling of debris into the bays. A skimmer wall located below the surface also prevents floating debris from being drawn into the plant. Second, the percentage of river water withdrawn into the Beaver Valley Power Station was very small compared with the total flow. Flow data, provided by the Ohio River Sanitation Commission's East Liverpool, Ohio, gage (MP 40.2) for November and December, 1985, show monthly averages of 64,200 and 58,700 ft3/sec and maximum values of 127,500 and 141,300 ft3/sec, respectively, with only approximately 60 ft3/sec being withdrawn into the power station. When comparing the high numbers of clams collected in light of the above factors, it becomes apparent that there was a very large Corbicula population inhabiting the upper Ohio River drainage, above the 1985 study area. These clams most likely utilized a mucous excretion to relocate a distance of greater than 20 miles downstream to the Beaver Valley Power Station during the flood of November 1985. It is also significant that, in spite of this very large infestation of clams into the intake, no problems were encountered at the Beaver Valley Power Station and operations continued normally throughout the event.

The presence of N-methyl-L-aspartate (NMLA) was demonstrated in bivalves, Corbicula sandai and Tapes japonica. To our knowledge, this is the first report on the occurrence of NMLA in animal tissues. NMLA in bivalve tissues was identified according to the following findings; (a) its derivatives with (+)- and (-)- 1-(9-fluorenyl)ethyl chloroformate (FLEC) behaved identically with those of authentic NMLA, respectively, on high-performance liquid chromatography (HPLC), (b) its derivatives with (+)- and (-) FLEC behaved identically with (-)- and (+)-FLEC derivatives of authentic N-methyl-D-aspartate (NMDA), respectively, on HPLC and (c) its behavior on thin-layer chromatography was the same as those of authentic NMLA. We also describe the distribution of NMDA, and D- and L-aspartate, to which N-methylaspartate enantiomers are structurally related. NMDA was more widely distributed than NMLA in bivalves. These bivalves containing NMLA showed lower D-aspartate contents and D/(D+L) ratios of aspartate, than the bivalves containing NMDA.
