The impacts of Griffith University flow change are manifest across broad taxonomic groups Nathan, Queensland, Australia 4111 including riverine plants, invertebrates, and fish. Despite growing recognition of these relationships, ecologists still struggle to predict and quantify biotic responses to altered ABSTRACT / The flow regime is regarded by many aquatic flow regimes. One obvious difficulty is the ability to distin- ecologists to be the key driver of river and floodplain wet- guish the direct effects of modified flow regimes from im- land ecosystems.
