Drivers of phylogenetic structure in Amazon freshwater fish assemblages

Environmental and historical predictors values for the 97 sub-drainages of Amazon basin. Sampling effort (SamplingEffort), water color (WaterColor), network density (NetwD), the land cover heterogeneity (CoverDiv), and the soil heterogeneity (SoilDiv), area in km² (Area) and its log transformation (Area_log), distance from river mouth (DistMouth), the number of natural fragmentation (Waterfall) and its log transformation (Waterfall_log), sub-drainages present in Pebas lake region (Pebaslake), proportion of sub-drainage covered by sea water (Sea.water.at> 1Mya, Sea.water.at< 5Mya ) and its arcsin transformation (Sea.water.at>1Mya_asin). PCAs conducted in our study with variables of past climate (PC1_Diff_CurrentLGM, PC2_Diff_CurrentLGM, PC3_Diff_CurrentLGM) and current climate (PC1_GlobEnv, PC2_GlobEnv, PC3_GlobEnv, PC4_GlobEnv) and the raw values used to perform PCAs: mean, max and min annual temperatures and precipitations at the Last Glacial Maximum (PastClimate) and of the current climate variables (CurrClimate); and the mean, minimum, maximum, range of elevation in m.
