Water regime dependence of fish in the wet-dry tropics

This project has improved understanding of the potential ecological impacts of changes in dry season flow regimes of tropical river ecosystems caused by water resources development in these catchments. The project investigated variation in fish distribution and ecological requirements across a natural flow regime gradient using field sites, and document indigenous knowledge on fish in the Daly River. This information has been used to develop models, based on BBNs, to predict the impact of different (more)...

The Madden- Julian Oscillation (MJO) and its relevance to the southern hemisphere tropics and extratropics

This talk will provide a review of recent work on the impact of the Madden-Julian oscillation (MJO) on the Tropics and extratropics of the southern hemisphere, but with particular emphasis on the Australian region. There, an influence can be detected in rainfall or circulation in most locations during all of the traditionally-defined seasons. As expected, the greatest rainfall impact of the MJO is in northern Australia in (austral) summer, where it is (more)...
