Data from: Specific leaf area is lower on ultramafic than on neighbouring non-ultramafic soils

These are datasets in csv format for ultramafic and non-ultramafic
sampling sites where specific leaf area (SLA) was collected in five
climatically diverse regions: Puerto Rico (tropical wet), Costa Rica
(tropical dry), South Africa (subtropical), California and Lesbos (both
with Mediterranean climate). The datasets include plant species level mean
SLA values, regional coordinates, regional climate data, bioclimatic
variables for individual sites, and a joined dataset that includes site
level coordinates and climate variables. The R script to reproduce all
analyses and figures is also included.
