Abstract Of 173 zooplankton samples taken by sampling monthly over 3 years at 3-7 stations within the Moreton Bay estuarine system, 122 contained Acartia pacifica, 115 contained A. tranteri, 141 contained Pseudodiaptomus mertoni and 89 contained P. colefaxi. Each of these species was frequently a numerically dominant/subdominant calanoid in the plankton, and all were within the nine most dominant of the 67 species recorded. Relationships between occurrences of these species pairs and three variables-species dominance level, ambient temperature and ambient salinity-are presented and discussed. A. tranteri was found to be relatively cool-stenothermal and euryhaline while A. pacifica was more warm-stenothermal and less curyhaline. These differences indicate consequent seasonal and estuarinegradient separation of the species. Similar though less distinct separation was found between the Pseudodiaptomus species, P. colefaxi being relatively eurythermal and euryhaline while P. mertoni is relatively warm-stenothermal and polystenohaline. The implications of such differences in salinity and temperature requirements in terms of species succession are briefly discussed in relation to studies elsewhere.
