The entangled multi-level responses of Mytilus galloprovincialis (Lamarck, 1819) to environmental stressors as detected by an integrated approach.

摘要: Abstract Anthropogenic pressure adds up and interacts with the effects of climate change a varying magnitude potential changes depend on species’ Life History (LH) traits, local environmental conditions co-occurrence several stressors. Stressors exert negative marine biota when acting as single factor, but may be amplified more than one stressor work in combination, producing interacting biodiversity ecosystem functioning. The impairment individual functional traits (FT) leads to strong rebounds LH this have ecological consequences. No studies actually relate FT antioxidant enzymes multiple In paper we investigate food concentration, temperature hypoxia metabolic expressed by proxy such respiration rate feeding behaviour (Catalase, Superoxide dismutase, Glutathione S-Transferase, peroxidase) for bivalve Mytilus galloprovincialis. Mussels were exposed three temperatures (12, 20 28 °C) under normoxic (8 mg O2 l−1) hypoxic (~2 mg conditions, concentrations ranging from 0.9 3.5 μg chlorophyll l−1. results show that FTs affected temperature, availability, outcome allowed us emphasise multi-scalar integrated approach is suitable detect monitor anthropogenic disturbance
