  1. Analyses were carried out for 150 individual mitochondrial sequences of burrowing parrots, 21 bio-climatic parameters, morphological subspecies identity, and Chilean and Argentinean eco-regions.
  2. --, added < 0.000001 to the regression sum of squares; CV: coefficient of variation; SD: standard deviation. No. of permutations = 9999. Temperature Seasonality: the standard deviation of the weekly mean temperatures expressed as a percentage of the mean of those temperatures (i.e. the annual mean). Precipitation Seasonality: the standard deviation of the weekly precipitation estimates expressed as a percentage of the mean of those estimates (i.e. the annual mean).
