Fields above the em dash (-) line are comparisons of the number of arid months, below are comparisons of the annual precipitation. One asterisk (*) indicates significance at the 5% level, two asterisks (**) indicate significance at the 0.1% level. Bold numbers indicate statistically significant differentiation between species (biome switch).
