DESCRIPTION:from the James Cook University in Australia\nand currently a B
 renda Ryman Visiting Research Fellow at Girton College\n\nAt all scales pl
 ant and atmospheric processes are interdependent.  At the heart of this ve
 getation-atmosphere feedback loop is the most significant bioregulator on 
 the planet: the stoma.  These tiny valves in the leaf epidermis directly s
 ense and integrate a variety of environmental and internal signals to regu
 late plant gas exchange in a way that tends towards optimal CO2 uptake wit
 h respect to water loss. Intriguingly\, different plant taxa and community
  assemblages perform this function differently\, according to different ec
 ological strategies and inherent physiological constraints.  I will discus
 s the physiology and macroevolution of elements of the stomatal control sy
 stem across multiple scales\, drawing on examples from my studies with a d
 iversity of species and landscapes\, and including recent findings from se
 veral collaborations here at Cambridge.
