OOS 50 - Carbon or Sinks: The Causes of Tree Growth
Limitation
A105, Oregon Convention Center
Organized by: ET Wiley, S Asao
Moderator: DL Hoover
This session addresses the debate over carbon versus sink
limitation to tree growth, with discussions covering specific cases of
carbon or sink limitation, the validity of evidence used to distinguish
between the types of limitation, and the relevance of carbon and
sink limitation to ecosystem processes.

Functional Ecology and Management
A107, Oregon Convention Center
Organized by: B Weber (weberb@rhrk.uni-kl.de), J Belnap
Moderator: J Belnap
Biological soil crusts are a critical component of dryland
ecosystems, contributing to the diversity, functionality and nutrient
