Here, we examine spatial concordance in global diversity patterns for five freshwater taxa (i.e. aquatic mammals, aquatic birds, fishes, crayfish and aquatic amphibians) and investigate the environmental factors driving these patterns at the river drainage basin grain. We find that species richness and endemism patterns are significantly correlated among taxa. We also show that cross-taxon congruence patterns are often induced by common responses of taxa to their contemporary and historical environments (i.e. convergent patterns). Apart from some taxa distinctiveness (i.e. fishes), the climate/productivity' hypothesis is found to explain the greatest variance in species richness and endemism patterns, followed by factors related to the history/dispersion' and area/environmental heterogeneity' hypotheses. As aquatic amphibians display the highest levels of congruency with other taxa, this taxon appears to be a good surrogate' candidate for developing global freshwater conservation planning at the river drainage basin grain. specialized amphibians birds congruence crayfish endemicity fish freshwater global scale mammals species richness 036 082 82 2 365-376 2013 0021-8790 https://www.documentation.ird.fr/hor/fdi:010059006 10.1111/1365-2656.12018 0021-8790 [F B010059006] https://www.documentation.ird.fr/hor/fdi:010059006 https://www.documentation.ird.fr/intranet/publi/2013/03/010059006.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2013-04-02 2017-08-23 fdi:010059006 fre
