Background

Plant physiology, ecology, and evolution.
 

Current Research

We explore why and how plant community composition changes across ecological settings and what the ecosystem-level consequences are of these changes. Our focus is typically not at the species but at the trait composition level, as selection will be acting within and among species via their expressed functional traits. We ask whether particular plant traits or suites of traits lead to differences in plant distribution and performance to understand the linkage between structure and function. Additionally, we examine these linkages within an evolutionary framework, investigating where in phylogenies the greatest divergences in trait values occur, as well as whether traits change in a coordinated fashion across phylogenies.

Currently the lab has three large themes:

  1. Understanding interspecific differences in wood decomposition rates
  2. Plant functional traits relationships and environmental gradients (field data)
  3. Global functional trait databases (compilations)
