AB - NOTES ON THE MOLTING CYCLE, DEVELOPMENT OF SEXUAL CHARACTERS AND SEX RATIO IN CALANUS HYPERBOREUS 1) BY ROBERT J. CONOVER Woods Hole Oceanographic Institution, Woods Hole, Mass., U.S.A. The majority of marine plankton animals have relatively short life cycles, but in high latitudes one or more years may be required by plankton organisms to complete a generation. Such an organism is the copepod Calanu.r hyperboreus ( Kroyer ) , probably the most important epizooplankton animal in terms of biomass in the Arctic (Grice, 1962). In boreal and temperate regions this species occurs in deeper waters, yet still retains its annual life cycle even though the seasons of breeding, development, and molting may differ (Conover, 1962). Because of its large size, C. hyperboreu.r can easily be recognized and sorted in the field. In this study, some individual living C. hyperboreus have been brought back to the laboratory and maintained for over a year (see Conover, 1960, 1962), during which time they have passed through a portion of their life cycle. Other material gathered from different locations at different seasons of the year has been preserved for comparison and to supplement laboratory observations. I would like to acknowledge the contribution to
