    • ‘Periods of decreased river flow enlarge the proportion of the estuary habitat favored by stenohaline organisms preferring highly saline conditions.’
    • ‘Considering the three patterns of ontogeny of postembryonic osmoregulation, it is clear that the studied species classed in pattern I (all stages are weak osmoregulators or osmoconformers) are marine stenohaline osmoconformers.’
    • ‘In one group of species, osmoregulation varies little with developmental stage; the adults of these species, mostly marine and stenohaline, are weak regulators or osmoconformers.’
