  1. Time-for-Accumulation Hypothesis (TfAH) is supported for both latitudinal and longitudinal gradients. Diversification Rate Hypothesis (DRH) and Asymmetrical Dispersal Hypothesis (ADH) are not supported and may act as buffers against the effects of differential colonization times on the spatial heterogeneity of biodiversity. Areas: U = Australasia, OW = Old World, NW = New World, W = West, E = East.
