“…The coarse and very fine sediment fractions, the high water temperature and the low benthic organic matter content in very fine fraction of sediment provided suitable habitat for C. fluminea and resulted in high biomass values. These results are in accordance with previous studies, which demonstrated that C. fluminea reached its maximum abundance at sites with coarse and find sand, or small gravel sized substrate (McMahon 1983;Belanger et al 1991;Bagatini et al 2007;Sousa et al 2008c).…”

Spatial and temporal variation in biomass and size structure of Corbicula fluminea in Danube River catchment, Hungary

et al. 2012

The aim of this study was to reveal the spatial and temporal variation in biomass, density, and size structure of the invasive clam, Corbicula fluminea in the Danube River catchment and to explore the environmental factors determining these patterns. Samples were taken seasonally during the years 2007 and 2008 at 15 sites located along a river continuum from a second order stream to the Danube River. C. fluminea was the most abundant species in the main arm of the Danube; however, it was found in great density in the side arms, too. In the Ipoly River it only occured close to the conjuction, and it was not present at all in the second and third order streams. Regression models were developed to predict dry mass (DW, g) from linear body dimension [shell length (L), mm]. For the description of length-dry mass relationship, the power function (DW = a * L b ) was applied. The highest density, biomass, and mean shell length were 178 ind. m −2 , 24.9697 g DW m −2 , and 21.99 mm, respectively. ANOVA detected significant spatial variation in biomass; however, significant temporal variation was not recorded between the years, only among the seasons. Multiple linear regressions were used to find the relationship between the biomass and the environmental parameters. The coarse and very fine sediment fractions and the high water temperature provided suitable habitat for C. fluminea. Although statistically significant correlation was not detected between the chlorophyll-a content of water and the biomass, the highest biomass values were recorded at sites with high chlorophyll-a value.

“…In most cases, the highest coefficients of determination were found in power function (Smock 1980;Burgher & Meyer 1997). As a linear body dimension the shell length of C. fluminea was generally used (Bagatini et al 2007). To the biomass calculation 216 specimens including 14 size categories were examined.…”

“…Indeed, they have been used as bioindicators since their presence is indicative of water quality, particularly after alterations to the environment (Verdonschot, 1989). Consequently, there has been considerable research interest in biomass and production of benthic macroinvertebrates communities (Benke et al, 1999;Bagatini et al, 2007;Takahashi et al, 2008). They also play an important role in trophic interactions and energy flow through aquatic ecosystems (Benke et al, 1999).…”

-The influence of the sediment grain size and the trophic status of the reservoirs on the composition, richness and biomass of Oligochaeta community was tested. Samples were taken from the littoral and profundal zones of 30 neotropical reservoirs from six different watersheds during two hydrological periods (dry and rainy seasons). The sample units were ordinated, with principal component analyses, according to differences in the sediment grain size, sample depth and dissolved oxygen. The results of a multiple response permutation procedure (MRPP) analysis revealed significant differences in species composition between littoral and profundal zones, trophic status (oligotrophic, mesotrophic and eutrophic) and different watersheds. The environment-species relationship was tested using redundancy analyses. In order to test which environmental variables, either granulometric or limnological, influenced the Oligochaeta community variability we used a partitioning procedure of inertia. Local variations, including reservoir zone and trophic status, were primarily influenced by differences in sediment type and depth. Significant differences in the total biomass between zones, trophic status, watershed and hydrological period were also demonstrated by a KruskalWallis or Mann-Whitney test. The most prevalent taxa were the cosmopolitan tubificids Bothrioneurum sp. and Branchiura sowerbyi, and the naidids Dero (Dero) digitata and Pristina breviseta, which are dependent on periphyton for food. Higher biomass values were recorded in mesotrophic reservoirs, due to increased nutrient availability and adequate dissolved oxygen supply. Our results indicate that the Oligochaete community structure is directly influenced by local environmental variation in neotropical reservoirs; and that the sediment grain size is the most important factor in determining the Oligochaete community structure.

“…Nesse estudo houve menores valores de pH na época chuvosa, uma vez que no período seco os íons se encontraram mais concentrados. Os dados de pH aqui obtidos corroboram com Bagatini et al (2007) que encontraram a espécie em águas neutras (7,1 a 7,4) no reservatório Rosana no rio Paranapanema. Já Surianie et al (2007) encontraram C. umínea em valores de pH de 5,49 a 11,18.…”

RESUMOEste estudo teve por objetivo contribuir com novos registros da espécie exótica Corbicula umínea no Rio Manhuaçú, Minas Gerais. Para amostragem foram investigados diferentes ambientes ao longo do rio, nos períodos chuvoso e seco de 2014. Foram encontrados 147 indivíduos. O comprimento variou de 0,1 cm e 1,6cm e o peso total obteve amplitude de 0,0017 g e 0,9943 g. A relação entre o tamanho da concha e o peso indicou que o ajuste exponencial obteve uma curva exponencial com r² = 0,8599. Palavras-chave: Bivalve; Ambiente Lótico; Molusca; Espécie Exótica; Espécie Invasora.
