Ball (Marilyn) Group - Ecophysiology of salinity and freezing tolerance

We study how physiological adaptations and responses to environmental stresses affect the structure and functioning of plant communities.

About

The Ball Group studies how physiological adaptations and responses to environmental stresses affect the structure and functioning of plant communities along environmental gradients. Current projects are exploring the role of plant morphology in evolutionary trade-offs between stress tolerance and coordination of hydraulic and photosynthetic activity in leaves. This trade-off has implications for the structure, display and function of leaves that might constrain carbon gain and affect the capacity of evergreen species to respond with growth to climate warming and increasing atmospheric [CO2]. The work is being conducted on mangroves, temperate evergreen sclerophylls, and Antarctic vegetation.

Unusual portraits of RSB members Marilyn Ball and Jack Egerton were part of an exhibition at the National Portrait Gallery, entitled 'So Fine: Contemporary women artists make Australian History'. The portraits are part of a group of six sculptures made of bones, skins, furs, fabrics and other natural materials.
