Abstract |
The burrowing behavior of three polychaete species (Nereis virens and Nephtys caeca) was examined after variable exposure periods (7, 14, 21 and 28 d) to sediment contaminated with a cadmium concentration of about 40 mg/kg (dry weight). Most comparisons of burrowing times and rates between exposed and unexposed worms were not statistically significant. Those that were significant were relatively minor, e.g., a maximum reduction in burrowing time of 6.3 s, and probably would have little ecological relevance. The feeding behavior of G. dibranchiata on the polychaete Euzonus mucronata was not affected by a 28-d exposure to cadmium-contaminated sediment. |
