Ecological niche models
We modeled the ecological niche of 47 clades from 21 taxa (Table 1). After filtering, our final dataset included a total of 65,373 georeferenced records representative of the known distribution of the studied species (range per clade 25-10,596). One out of fourDipodomys merriami clades presented only 7 occurrence records, therefore this clade was not included in further analyses. AUC values for the niche models were on average 0.961 (median: 0.972; range 0.839-0.999; Supporting Information includes other model evaluation metrics). The three most common variables selected to build the models were mean annual temperature (bio1), temperature seasonality (bio4) and precipitation seasonality (bio15, Table 1).
