Gene ‘poaching’ the secret to eucalypt resilience?
Despite what most people think, identifying eucalypts is no easy task. A tree that may look like an alpine ash might also harbour genes more commonly found in a mountain ash tree downslope. In fact, this tendency of eucalypts to readily ‘poach' genes from related species may hold the key to their survival in a rapidly changing climate.
Catching fires in a neural net
What do you do in your spare time? Bit of gardening? Swimming? Cooking? How about training a computer neural network to predict where bushfires might break out?
Birds on the edge: species at risk from climate change
2002 was a dry year in the rainforests of Cape York Peninsula, and proved tough for local bird species, particularly the white-faced robin – a delightful little bird that takes insects from the forest floor. Of the robins that were tagged, only around 25 per cent survived that year (in normal years, annual survival tops 70 per cent).
