摘要:
The breeding cycles of lugworm taken from three locations on the east coast of Ireland have been investigated through examination of coelomic fluid samples which contain the gametes, taken at monthly intervals. These reveal major differences in the timing and duration of breeding between the populations despite their geographic propinquity. The differences in breeding cycle cannot be ascribed to varietal or species differences and may arise from the different habitats occupied by the lugworm populations studied.
