This file contains all the summary information from studies found in a literature search for common-garden or reciprocal-transplant experiments testing the hypothesis that there is a genetic basis to elevational or latitudinal variation in LMA, Nmass, or Narea within a species of plant. Column titles: STUDY NAME; author's last name and year published (see Appendix S2); Altitude common garden, whether the gradient is elevational; n. altitudes or latitudes, how many sites were sampled; Latitude common garden, whether the gradient is latitudinal; other, details if necessary; Trait(s), which traits were sampled; Genetic basis, whether statistically significant genetic basis was found; Effect size type, what statistical test/model was used; LMA, Nm, and Na, which of the 3 traits were sampled.
