Concern about tree decline in rural landscape is widespread, and disturbingly climate change is predicted to exacerbate this problem. Past ill-considered tree plantings have proven to be economically wasteful, achieved limited ecological resilience and negligible improvement of biodiversity values. Using Tasmania as a 'model system', we will advance this problem by undertaking research to determine how seedling establishment, tree growth, carbon storage and water use are influenced by landscape setting, management history, climate change, species type and local varieties. This research will provide a much needed evidence to devise ecologically sustainable tree-plantings in southern Australia.Read moreRead less
Seaweed forests of the future: responses to ocean acidification and warming. The aim is to discover if rising levels of oceanic carbon dioxide will offset negative effects of ocean warming on seaweeds, using targeted physiological experiments together with novel molecular diagnostics. Seaweeds create habitats and food for shellfish and fish, and play a crucial role in long term ‘blue carbon’ storage. They are predicted to benefit from future carbon dioxide enrichment, but to test this forecast r ....Seaweed forests of the future: responses to ocean acidification and warming. The aim is to discover if rising levels of oceanic carbon dioxide will offset negative effects of ocean warming on seaweeds, using targeted physiological experiments together with novel molecular diagnostics. Seaweeds create habitats and food for shellfish and fish, and play a crucial role in long term ‘blue carbon’ storage. They are predicted to benefit from future carbon dioxide enrichment, but to test this forecast requires a detailed understanding of the mechanisms used by seaweeds to acquire dissolved inorganic carbon. The expected outcome is robust predictions of how the primary productivity of coastal waters will respond to future high carbon dioxide conditions, enabling human adaptation to environmental change.
