Current global warming and climate extremes are markedly altering the functioning and composition of Australia’s
grassland ecosystems with consequences to food security (grazing industry), biodiversity, biosecurity (weed
invasions), and public health (grass pollen is the world’s most harmful outdoor aeroallergen). Yet, despite their
importance, key questions remain on how climate change is altering the phenology, species composition, and
pollen dynamics of grassland areas. In this project we will integrate satellite phenology data with pollen aerobiome
analyses to address key questions on the relationships among spatial and temporal shifts in grassland phenology,
grass species composition and pollen seasonality and exposure.
