dc.description.abstractIn this study, the population dynamics, life history tactics and ecophysiology of two intertidal, marine isopods Gnorimosphaeroma luteum and G. oregonense were examined. Seasonal occurrence of different sexual stages in the field, sexual dimorphism between sexes (males larger than females) and laboratory studies provide corroborative evidence that both species are protogynous. Laboratory reared mature females hatched their brood and moulted as immature males a variable number (1-3) of times before moulting to mature males. Sex change may be facultative in both species, because small immature males occurred in field populations and some laboratory-reared juveniles developed directly into males and did not undergo sex change. Social mediation of sex change may also occur in both species. Although there were significant differences in energetic values, consumption, absorbtion, total lipid content and resting respiration rates among sexual stages within G. luteum and G. oregonense, patterns of allocation among sexual stages between species were similar.
