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).
