Abstract

The life cycle of the ostracod Cypideis torosa was studied in a hypersaline environment at Santa Pola, a coastal salt marsh of the Western Mediterranean. Benthic samples were obtained monthly and several environmental factors were recorded simultaneously in situ. In Santa Pola, C, torosa is able toproduce eggs all year round and, in contrast with previous studies, showeda bivoltine reproductive pattern. The first generation, starting from eggsproduced in spring, attains adult size after a mean time of 154 days. The second generation, starting in autumn, developed more slowly, attaining adulthood after 196 days on average. The male:female sex ratio is below 1 in spring and autumn, when maximum reproduction took place, and it was not different from one after these periods. The mean shell size of adult individuals underwent significant changes throughout the year: late winter males and females are the longest. Those adult individuals that remained alive after the spring reproductive period showed the lowest shell length values. We discuss how temperature and salinity may affect the development of juveniles and adult shell size.
