Abstract:
The intraspecific variation in the number and distribution of paragnaths in ten populations of Nereis ( Neanthes ) virens collected throughout its range was examined. Significant differences among populations are found in the total number of paragnaths and in each paragnath group. The unweighted pair-group method using arithmetic averages cluster analysis revealed three distinct clusters separating Canadian populations, Europe/USA populations and the Japanese population, suggesting the implication of either restricted gene flow, selection on paragnath patterns or phenotypic plasticity. Comparison with a previous genetic study suggests that morphological variants represent ecotypes of the single, widely distributed N. virens species.
