From: Climatic niche differences among Zootoca vivipara clades with different parity modes: implications for the evolution and maintenance of viviparity

Fig. 8

Classification tree for the annual period resulting from recursive partitioning with parity mode (oviparous vs. viviparous) as response variable and the six annual climatic covariates (Appendix S1) as predictors. The variable that decreased the impurity the most is indicated and its threshold value is given (BIO4, units: degrees Celsius). Grey leaves represent the cases classified as oviparous and white leaves represent those classified as viviparous. Numbers within leaves correspond to the number of correctly and incorrectly classified cases (left and right values, respectively). Numbers next to each leave, refer to the number per clade of correctly (underlined) and wrongly classified cases
