The role of calcium concentration in the invasive capacity of Corbicula fluminea in crystalline basins

Homogenization of Macroinvertebrate Assemblages and Asiatic Clam Corbicula fluminea Invasion in a River of the Arid Patagonian Plateau, Argentina

“…When resources are limited in the water column, invasive fastgrowing bivalves can negatively affect the survival and growth of native bivalves (Crooks, 2001;Ferreira-Rodríguez et al, 2017). Furthermore, invasive species may have a competitive advantage due to their higher trophic plasticity (Novais et al, 2016).…”

Decay and persistence of empty bivalve shells in a temperate riverine system

“…In estuarine areas, low salinity values and high productivity can contribute to different decays, with the dissolution rates being a result of the combination of physical, biological, and chemical processes (Waldbusser et al, 2011). Available data of the area (see Sousa et al, 2007;Ferreira-Rodríguez et al, 2017) suggest that the water in the study sites has low Ca 2 content. In fact, Ferreira-Rodríguez et al ( 2017) observed low Ca 2 content in the soft bodies of C. fluminea collected in the Minho River, which corroborates with the fact that Ca 2 concentrations in Minho River is low.…”

“…The water of Minho River is undersaturated with CaCO 3 (Ca 2 : 9.0 mg l −1 ; mean total hardness CaCO 3 : 24.4 mg l −1 ; mean pH: 7.6; for more details see Sousa et al, 2007 andFerreira-Rodríguez et al, 2017).…”

Biometric conversion factors as a unifying platform for comparative assessment of invasive freshwater bivalves

“…Contrastingly, positive slopes indicate a greater investment in soft tissue production, which may include respawning or gravid states. Similarly, abiotic factors such as the availability of calcium or the acidity of water may limit the development of hard tissue structures (Ferreira-Rodríguez et al, 2017). Nevertheless, despite both positive and negative trends existing among populations, calculated linear slopes were observed to be small with low R 2 values.…”
