The world's rivers - the single largest renewable water resource for humans and a crucible of aquatic biodiversity - are in a crisis of ominous proportions, according to a new global analysis co-authored by a researcher at The University of Western Australia.
Drought, salinity, flooding and extreme temperatures threaten many plants essential to humankind - and scientists at The University of Western Australia have discovered how they respond to these challenges.
Researchers at The University of Western Australia (UWA) Institute of Agriculture have confirmed that wheat varieties tolerant to iron, manganese and aluminium perform better in acidic, waterlogged soils, while varieties intolerant to such ion toxicities grow poorly and yield considerably less.
Lead researcher Dr Hossein Saberi explained that waterlogged soils were oxygen deprived, which increased iron and manganese concentrations to toxic levels, while acidic soils had increased concentrations of aluminium ions that were also toxic to plants.

Lead researcher Winthrop Professor Steven Smith, of UWA’s Centre of Excellence in Plant Energy Biology, said understanding how plants grow under stressful environmental conditions was vital for food, fuel and fibre production.
The discovery of new genes for two of the world's most common eye diseases could lead to new treatments, according to leading ophthalmologist, Winthrop Professor David Mackey, from The University of Western Australia.
