Untangling key abiotic predictors of terrestrial mammal diversity patterns across ecoregions and species groups in Kenya

•Diversity-predictor associations differed between species groups and ecoregions.•Annual average and seasonality in temperature and precipitation and human footprint were the strongest predictors.•Lower explained diversity variances in the mesic than xeric ecoregions.•Curbing human impacts destabilizing long-term climate regimes is vital to terrestrial mammal conservation efforts.
