luscan maximum We spans determined by long- term cycles in benthic comm~aities? Oecologia, 67(2): 177-182.

A review of the maximum longevity of bivalves and gastropods indicates that a greater than average number of life spans coincide with the periods of long-term cycles in marine communities. Gastropods and bivalves are affected differently, longevities being determined by some cycles more than others in each group. Overall, molluscan longevities tend to be slightly longer than the corresponding cycle, sug- gesting that there is selection pressure for life spans slightly longer than the cycle controlling recruitment success and generational replacement.

All stages were present throughout most of the year, but spawning was most concentrated during late winter, summer, and autumn. Three cohorts ap- peared to be completed during the year; each proceeded through development from early nauplii to adults at the same rate, probably because the third copepodite and older life stages migrate vertically during the day to depths below 250 m, where water temperature does not vary seasonally. The recom- meneement of reproduction in February and March, following a hiatus in female reproduction from November to January, initiates a cohort and pro- vides an impetus for a cycling of the population age structure.
