Eco-physiological responses to salinity changes across the freshwater-marine continuum on two euryhaline bivalves: Corbicula fluminea and Scrobicularia plana

Investigating a transcriptomic approach on marine mussel hemocytes exposed to carbon nanofibers: An in vitro/in vivo comparison

“…P-values were then corrected using false discovery rate (fdr) using the R-package hmisc. To create an integrative analysis, partial least square discriminant analysis (PLS-DA) was used to determine if test conditions could be discriminated from the control (Bertrand et al, 2017;Cho et al, 2008). PLS-DA was selected as it has good performance when dealing with multi-collinear data with small samples and many variables (genes).…”

Exposure to Elevated Concentrations of Major Ions Decreases Condition Index of Freshwater Mussels: Comparison of Metrics

“…Changes in environmental salinity can affect energy storage in bivalves. Depletion of stored energy has been documented in marine bivalves exposed to low-salinity water (Kumar et al 2015;Bertrand et al 2017) and in the freshwater clam Corbicula fluminea exposed to high-salinity water (Bertrand et al 2017). However, to our knowledge, changes in energy storage in freshwater mussels as a result of exposure to elevated salinity, particularly the mixture of major ions found in mining-impacted streams, have not been evaluated.…”

“…Evaluating energy storage in bivalves as a response to seasonal or environmental changes requires distinguishing between energy reserves in soft tissues and structural biomass (Van Haren and Kooijman 1993). Energy storage in soft tissues can be measured directly, as glycogen, lipid, or protein content (e.g., Bayne 1982;Kumar et al 2015;Bertrand et al 2017). Energy storage also can be measured indirectly using the entire animal.…”

Distribución y dinámica poblacional de la almeja asiática Corbicula fluminea (Bivalvia, Corbiculidae) en ríos de Uruguay

“…Se ha probado que esta línea de arrastre contribuye a la flotabilidad de las almejas de hasta 14 mm de longitud total, promoviendo la deriva hacia nuevas localidades y favoreciendo la dispersión de la especie (Rosa et al 2014). Sin embargo, debido a que C. fluminea no soporta salinidades mayores de 14-15 (Morton and Tong 1985;Argente 2016;Bertrand et al 2017), las cuales son comunes frente al departamento de Montevideo (Nagy et al 1998), la invasión no podría avanzar más allá de sus costas. Otra especie invasora de la región, el mejillón dorado (Limnoperna fortunei), también presenta su límite este de distribución en esta zona (Brugnoli et al 2005).…”
