Understanding the evolution of mammal pollination in the south-west Australian biodiversity hotspot and its vulnerability to landscape modification While Australia is a global center for bird pollination, there is comparatively little evidence for pollination systems specialized in mammal pollination. The honey possum is a specialist nectarivore, endemic to the south-west Australian biodiversity hotspot, where they were originally common in sandplain habitats dominated by Proteaceae and Myrtaceae. While it has long been speculated that plants may be adapted specifically to pollination by honey possums, this hypothesis has never been rigorously tested. The initial aim of this project is to test for specialization on honey by members of Dryandra, a clade of Banks, which exhibits multip
