Project Member(s): Eamus, D.

Funding or Partner Organisation: Australian Research Council (ARC Discovery Projects)

Start year: 2014

Summary: This proposal addresses 2 fundamental questions: how do co-occurring species co-exist & why do Australian ecosystems have larger ecosystem water-use-efficiencies than those in the USA? This proposal will 1) determine the resilience of two contrasting arid-zone woodlands; 2) compare variation in hydraulic-related plant traits across co-existing species; and 3) determine the relative contribution of changes in assimilation and stomatal conductance to variation (across species and time) in water-use-efficiency. Outcomes of this work include a mechanistic understanding of the behaviour of water-limited woodlands in current and future climates. This is significant because such biomes are globally important and are home to 2 billion people.
