Table 1. Environmental variables retained to model the climatic niches of the Peruvian peppertree in Mexico.

The table shows the relative contribution of each variable to explain variance in each model (generalized, adult and regeneration niche models).

Variable	Generalized niche model	Adult niche model	Regeneration niche model
Annual Mean Temperature	17.6%	18.5%	19.4%
Mean Diurnal Range of Temperature	2.8%	3.1%	3.9%
Isothermality	40.1%	30.4%	31.4%
Annual Precipitation	21.4%	22.5%	22.7%
Precipitation Seasonality	4.5%	12.4%	12.3%
Precipitation-Driest Month	2.1%	1.2%	1.6%
Precipitation-Coldest Quarter of the Year	11.5%	11.9%	8.7%
