We use a sister-pair of widespread savanna trees (Melaleuca argentea and M. fluviatilis) to test the influence of putative barriers on diverKeywords: allopatry; biogeography; dicotyledon; dispersal; evolutionary biology; genetic variation; niche partitioning; savanna; spatial distribution; speciation (biology); sympatry; tropical forest; Australia; Carpentaria; Melaleuca; Melaleuca argentea; Melaleuca Australian monsoon tropics; Biogeography; Carpentaria Basin; CpDNA; Ecological niche modelling; Melaleuca; Niche divergence; Speciation; SympatryNiche differentiation and spatial partitioning in the evolution of two Australian monsoon tropical tree species201310.1111/jbi.120272016-02-24
