Abstract:
Here we investigate differences on the energetic strategy of thread drifters (3-4mm) and sedentary settlers (9-10mm) of Cerastoderma edule over a wide range of salinities (3, 5, 10, 15, 20, 25, 30 and 35) in a laboratory experiment. Several physiological indicators (clearance, respiration and excretion rates and O:N) were measured during acute (2 days) and acclimated responses (7 days of exposure) for both size classes. Our results revealed a common lethal limit for both developmental stages (Salinity <15) but a larger physiological plasticity of thread drifters than sedentary settlers.
