Description
Summary:The responses of several arctic marine benthic crustaceans to sediments experimentally contaminated with crude oils have been examined. The amphipod Onisimus affinis overwhelmingly selected clean rather than oil-contaminated sediments. The response was most pronounced at low oil concentrations and the ability to discriminate was abolished at the highest concentrations tested. Weathering of the oiled sediment for 1 week reduced the avoidance response. Another amphipod and two isopod species tested did not discriminate consistently between oiled and clean sediments. Potential ecological consequences of these behavioural responses are discussed.
