Principal component analysis including climatic, space, and soil variables related to quality site classes of Nothofagus antarctica forests in southern Patagonia. SC is the site class where each stand is growing; S and T before the number of each site determine if the stand is located in Santa Cruz or Tierra del Fuego, respectively; BIO2 (maximal monthly temperature − minimal monthly temperature); BIO3 (isothermality ((BIO2/BIO7) × 100)); BIO4 (temperature seasonality (standard deviation × 100)); BIO5 (maximal temperature of the warmest month); BIO6 (minimal temperature of the coldest month); BIO7 (temperature annual range (BIO5–BIO6)); BIO9 (mean temperature of the driest quarter); BIO10 (mean temperature of the warmest quarter); Alt, altitude; C, soil carbon concentration; C:N, soil carbon:nitrogen ratio; EVPT, evapotranspiration; N, soil nitrogen concentration.
