Changes in gape frequency, siphon activity and thermal response in the freshwater bivalves Anodonta cygnea and Margaritifera falcata

The effect of seasonal temperature variation on behaviour and metabolism in the freshwater mussel (Unio tumidus)

“…in February (2-3 °C) and Summer (26-27°). Thus, increased valve closure in freshwater bivalves is a protection mechanism during times of stress, as previously seen when exposed to acutely elevated temperatures (Rodland et al, 2009), or adverse conditions such as low water oxygen concentration (Chen et al, 2001), or low pH (Pynnönen and Huebner, 1995).…”

Behavioral and mortality responses of the bivalves Scrobicularia plana and Cerastoderma edule to temperature, as indicator of climate change's potential impacts

“…When temperature conditions fall outside the organisms' thermal optimum they suffer adverse effects. Physiological stress is established at pejus temperatures originating behavioral responses (Rodland et al, 2009;Helmuth et al, 2010), that can be particularly severe when critical temperatures are crossed, often leading to mortality responses (Lannig et al, 2006;Rodland et al, 2009;Helmuth et al, 2010;Pörtner, 2010;Wither et al, 2012).…”

“…It may be useful to forecast mortality in ecotoxicological experiments and it can also be considered as a biomarker (Amiard-Triquet, 2009;Rodland et al, 2009;Helmuth et al, 2010). In this study, behavior was assessed using an integrated activity index quantifying the overall activity of the organisms (Verdelhos et al, 2015).…”

“…It has been described as affecting respiration and feeding (Gosling, 2004;Hicks and McMahon, 2005;Jansen et al, 2007;Rodland et al, 2009;Helmuth et al, 2010;Goh and Lai, 2014), leading to consequent behavioral changes (Ansell et al, 1981;Anestis et al, 2007;Rodland et al, 2009;Helmuth et al, 2010), and in severe cases to mortality responses (Casagranda and Boudouresque, 2005;Mouthon and Daufresne, 2006;Jansen et al, 2007;Parada and Molares, 2008;Verdelhos et al, 2014).…”

Sensitivity to selected contaminants in a biological early warning system using <i>Anodonta woodiana</i> (Mollusca)

“…As reported in many publications (Doherty et al, 1987;Salánki and V.-Balogh, 1989;Doherty, 1990;Jørgensen, 1990;Borcherding, 1992;Bayne et al, 1993;Borcherding and Volpers, 1994;Ham and Peterson, 1994;Englund and Heino, 1996;Rodland et al, 2009), the presence of xenobiotics, changes in temperature or light intensity, or altered particle concentration in water can have an impact on shell opening, and for this reason valve movement behaviour of mussels is indicated as a BEWS. The aquatic environment is the final sink of an increasing number of contaminants, most of which cannot be continuously and efficiently detected by the traditional chemical techniques (Hantge, 1993;Borcherding, 2006).…”
