Aim We examine biogeography and speciation patterns in Miliusa Lesch. ex A. DC. (~65 species) distributed in tropical Asia to understand the uneven distribution of its extant diversity, with Indo‐Burma having twice the species richness of peninsular India (PI) and four times that of Wallacea and Sahul. Location Tropical Asia. Taxon Miliusa (Annonaceae). Methods Phylogenetic reconstruction was performed using six plastid marker...

Aim How seasonal drought influences tree species distributions might shape future vegetation composition with impending changes to rainfall patterns. Theory suggests that across a seasonal drought gradient, dry‐tolerant species might have wider distributions than species sensitive to seasonal drought, which will be restricted to less seasonal conditions. As wet‐associated species drop out with increasing seasonality, the commu...
