Adaptability of the Amphipod Pontoporeia affinis (Crustacea: Amphipoda) to Salinity Changes

摘要

Salinity tolerance of the amphipod Pontoporeia affinis from the Baltic Sea was examined after acclimation to increased and decreased salinity. There were adaptive shifts in tolerance related to ambient salinity. A sharp change in salinity tolerance of amphipods occurred after acclimation to extremely low salinity.
