Understanding human impact on the water cycle is a tricky business – one clue is to be found in evapotranspiration. Novel use of satellite data is helping us measure something we can’t see.
Three quarters of the species that live in Australia don’t exist anywhere else in the world. We’re digitisation our collections to make the data easily available to have bigger impacts in areas like conservation, biosecurity and climate change.
For the first time, scientists have quantified how much water trees on the Murray-Darling floodplain need, and when they need it. The results show that we cannot tell the health of a tree just by looking at its canopy—we need to look inside the tree.
Global trade means global pests – not just in the way they spread but in the way they breed. Hybridisation of two moth species has now been confirmed, creating a fast-generating, pesticide-resistant mega pest which threatens broad-acre crops across the Americas. What’s next?
Out of the ashes of the Tathra bushfire, and stories of heartbreaking loss and survival, a picture is emerging of how research is helping to save properties and improve bushfire outcomes.
A new field guide to the sharks and rays of Papua New Guinea is supporting sustainable use of its shark and ray resources.
Climbing up an 80 m tower is all in a day’s work for some scientists. Read how they’ve been watching over Australia’s defining flora – eucalypts – as part of our land ecosystem observatory.
They’re one of the strongest bonds in chemistry and are not only unique in the way they can be used to fight fire, but unique in the way they leach through soils into the environment. A new paper suggests understanding first how PFAS chemicals behave in soils requires a large-scale soils study and, perhaps, a global research effort if we’re to work towards a solution.
