The influences of salinity and body size on biochemical (activities of glutathione- S-transferase, lactate dehydrogenase (LDH), acetylcholinesterase and digestive enzymes amylase and CMCase), physiological (feeding and egestion rates, energy reserves) and behavioural (burrowing speed) biomarkers were examined in the infaunal polychaete Nereis diversicolor. Only a few biomarkers were affected, including increased egestion rate and activities of CMCase and LDH at higher salinity, and higher egestion rate in larger worms. These findings reinforce the status of N. diversicolor as a robust sentinel species for estuaries which are environments that are particularly productive but also particularly at risk.
