The fresh water clam Corbicula fluminea is currently one of the most economically important aquatic species in China because of its nutritional value and pharmacological activity. In order to explore the potential of C. fluminea as a natural resource of bioactive compounds, a papain-released polysaccharide designated CFPS-2 was isolated. Chemical composition analysis indicated that CFPS-2 conta...

Corbicula fluminea is a freshwater bivalve mollusk that originates from Asia (Britton and Morton 1979, Mouthon 1981, Araujo et al. 1993). The species is known to be opportunistic, adapting to a wide range of lentic and lotic habitats and utilizing both filterand deposit-feeding strategies (Way et al. 1990). C. fluminea is 2 to 3 cm in size and has the typical oval-triangular clam shape. It also...

The Asian clam Corbicula fluminea, originating from Southeast Asia, was first recorded in Lake Constance in 2003 and developed local mass occurrences afterwards. Effects of harsh winter conditions in 2005/2006 associated with a strongly decreasing water level were studied at 3 different depths at and below the mean low water level (MLL, MLL -1 m and MLL -3 m). Low winter temperatures produced a...

The aim of this paper is to present the distribution of the non-native species Hypania invalida (Polychaeta) within Serbian waters. In 1971, this species was found for the first time in the Danube and the Sava Rivers. According to our results, H. invalida is now widespread within potamon-type rivers that are under the influence of hydromorphological alterations and exposed to intensive ship tra...

1. Two dominant drivers of species distributions are climate and habitat, both of which are changing rapidly. Understanding the relative importance of variables that can control distributions is critical, especially for invasive species that may spread rapidly and have strong effects on ecosystems. 2. Here, we examine the relative importance of climate and habitat variables in controlling the d...

Valve closure behavior in freshwater clam Corbicula fluminea is a biologically sensitive endpoint. The purpose of this paper was to derive an electrophysiological response model of C. fluminea to assess copper (Cu)-sodium (Na) interactions in gill membrane, whereby valve closure behavior and Cu toxicity could be monitored. The proposed model was based on the integration of Cu bioavailability, N...

BACKGROUND The Asian clam (Corbicula fluminea) is currently one of the most economically important aquatic species in China and has been used as a test organism in many environmental studies. However, the lack of genomic resources, such as sequenced genome, expressed sequence tags (ESTs) and transcriptome sequences has hindered the research on C. fluminea. Recent advances in large-scale RNA-Seq...

Selenium uptake from food (assimilation efficiency) and dissolved phase (influx rate) as well as loss kinetics (efflux rate) were compared between two bivalves, Corbicula fluminea and Potamocorbula amurensis. The effects of salinity and temperature on these kinetic parameters for both clam species also were evaluated. The Asiatic clam, C. fluminea, more efficiently assimilated Se associated wit...
