Rotifer communities of billabongs in northern and south-eastern Australia both areas littoral taxa predominated in open water. Diversity values (Shannon-Wiener, H’) were higher than recorded for tropical assemblages elsewhere. Up to 80 rotifer species co-occurred in Northern Territory billabongs. Brachionids notably were absent; there was an apparent displacement of trop

Environmental factors affecting hatching of rotifer (,) resting eggs and then stored for at least one month at 4°C in the dark. Light was found to be obligatory for termination of dormancy. Over the temperature range of 10–30°C (at 9.0‰ salinity), hatching was optimal (40–70%) at 10–15°C and decreased linearly with the rise in incubation temperature. Resting eggs in
