dc.contributorPatterns of reproduction, as measured by brood size and abundance, were studied for a population of the amphipod Grandidierella japonica (Am- phipoda: Gammaridea) in Newport Bay, California during the period of July 1993 to June 1994. Weekly measurements of temperature, salinity and photoperiod were also made at the study site. G. japonica reproduced year-round at this site. How- ever, both brood size and abundance declined during the winter months. Large females were found to have both a larger brood size and produced offspring of greater length. Physical factors, such as temperature and photoperiod, appear to play a role in the pattern of reproduction. However, biotic factors, such as food supply and predation, which were not measured in this study, appear to have an effect as well.
