Fig. 1: Comparison of resilience and resistance measures using the indices employed by Li versus Lloret.

Data availability

Raw tree ring width data were obtained from the ITRDB (version 7.15) at https://www1.ncdc.noaa.gov/pub/data/paleo/treering/. Gridded standardized precipitation evapotranspiration index data (SPEIbase version 2.5) with a spatial resolution of 0.5° were obtained from http://digital.csic.es/handle/10261/153475.

Code avilability

All statistical analyses were conducted in R (version 3.5.1) using the following libraries: lme4, lmerTest, MuMIn, performance, bestNormalize, emmeans, dplR, SPEI, ncdf4, effects, Taxonstand and taxonlookup. Additional R code is available at https://github.com/mmencuccini/ITRDB-data-analyses.
