Veligers of the invasive Asian clam Corbicula fluminea in the Columbia River Basin: Broadscale distribution, abundance, and ecological associations When the temperature was at 4Â☌–10Â☌ or the salinity was less than 0.5‰, the two Poker-chip Venus HAPs possessed better HAA compared with that of Corbicula clam. Furthermore, Poker-chip Venus HAPs possessed better HAA at a pH higher than 7.0. Moreover, HAA of the HAP purified from Poker-chip Venus was higher than that of the HAP of Corbicula clam. The two Poker-chip Venus HAPs possessed hemagglutinating ability (HAA) for erythrocytes of some vertebrate animal species, especially tilapia. However, only one HAP subunit was purified from Corbicula clam, and its molecular weight was 32 kDa. Purified HAP from Poker-chip Venus yielded two subunits with molecular weights of 26 kDa and 29 kDa. The molecular weights of the HAPs obtained from Poker-chip Venus and Corbicula clam were 358 kDa and 380 kDa, respectively. Hemagglutinating proteins (HAPs) were purified from Poker-chip Venus (Meretrix lusoria) and Corbicula clam ( Corbicula fluminea) using gel-filtration chromatography on a Sephacryl S-300 column. Purification and Characterization of Hemagglutinating Proteins from Poker-Chip Venus (Meretrix lusoria) and Corbicula Clam ( Corbicula fluminea) When the temperature was at 4Â☌-10Â☌ or the salinity was less than 0.5‰, the two Poker-chip Venus HAPs possessed better HAA compared with that of Corbicula clam. Purification and characterization of hemagglutinating proteins from Poker-chip Venus (Meretrix lusoria) and Corbicula clam ( Corbicula fluminea).Ĭheng, Chin-Fu Hung, Shao-Wen Chang, Yung-Chung Chen, Ming-Hui Chang, Chen-Hsuan Tsou, Li-Tse Tu, Ching-Yu Lin, Yu-Hsing Liu, Pan-Chen Lin, Shiun-Long Wang, Way-Shyan fluminea in the Minho river estuary (NW-Iberian Peninsula, Europe), an estuarine ecosystem in which C. Our objective was to characterize the food sources fuelling C. The Asian clam Corbicula fluminea is one of the most pervasive species in freshwater ecosystems. When gourmet is not enough: Organic matter sources supporting the production of Corbicula fluminea in an invaded estuary Nevertheless, despite such positive effects, earlier studies have showed that the density, biomass and spatial distribution of some species, especially native bivalves dramatically decreased after C. The mechanisms responsible for these positive trends still needs to be established although engineering activities and the increase in waste products may play essential roles. Crustacea, Insecta and Gastropoda are the main faunal groups responding positively to C. fluminea, with abiotic conditions also playing an important role in the observed patterns, both in brackish and freshwater settings. The comparative analysis indicate that macrozoobenthic density, biomass and diversity positively respond to increasing density of C. fluminea on the macrozoobenthos across five sites in the Minho estuary during three distinct periods of 2009 (winter, spring and summer). In this context, this work aimed to evaluate the correlation of different densities of C. fluminea can significantly alter the physical structure of the benthic environment, and the structure and functioning of this estuarine community. In the Minho estuary (NW of the Iberian Peninsula) this invasive species can reach densities up to 4000 ind m- 2, occurring over large areas. The Asian clam Corbicula fluminea is one of the most invasive species in brackish and freshwater ecosystems.
