Parameter estimates and 95% confidence intervals (CI) of the evolutionary rate (σ2) for ecophysiological traits in lianas and trees.

Amax = maximum photosynthetic rate; Rd = dark respiration rate; SLA = specific leaf area. Values of σ2 represent rates at which variance accumulates among species per unit time through a phylogeny with branch lengths in units of millions of years. P-values are for likelihood ratio tests against the chi-square distribution between a single-rate (homogenous) and a heterogeneous Brownian motion process. Bold cells indicate σ2 values for which 95% CI do not overlap between lianas and trees.
