Abstract

Highlights:
• Response to stress in P. viridis differed between impacted and natural populations.
• Response differences were large in the face of hypoxia but low in hyposalinity.
• Only mussels from the impacted Jakarta Bay acclimated to low oxygen.
• Jakarta Bay mussels had higher condition indices and lower relative shell weights.
• High condition indices correlated positively with hypoxia tolerance in mussels

Abstract:
It is an open question whether adverse habitat conditions, characteristic for many anthropogenically impacted coastal habitats, can determine resistance to abiotic stress in populations of residing invertebrates. We tested experimentally for differences in stress tolerance between individuals of the Asian green mussel Perna viridis stemming from the heavily impacted Jakarta Bay and from two natural sites, Lada Bay and Pelabuhan Ratu, West Java. Mussel performance under hyposalinity and hypoxia was assessed in laboratory assays by measuring fitness-related response variables, e.g. body condition index, relative shell weight, byssus production, respiration rates and survival. We found stress-specific and population-specific differences in mussel resistance to adverse conditions: Individuals from the impacted Jakarta Bay performed better under hypoxia than their conspecifics from the natural sites, whereas the latter were more resistant to hyposalinity. We explain these differences by differential acclimation to environmental conditions in the respective habitats and by diverging degrees of food supply.
