    Origin of distribution and genetic diversity of a savanna species

    Cyclic glaciations were frequent throughout the Quaternary and this affected species distribution and population differentiation worldwide. Combining ecological niche modelling and phylogeographical analysis, this study by Lima et al. suggests that the distribution of Eugenia dysenterica (Myrtaceae) radiated outwards from the central region of the Cerrado biome, and that its genetic diversity pattern is due […] More

    Phylogeny, biogeography and ecological niche modelling of Cardiocrinum

    Revealing patterns of evolutionary assembly in the Sino-Japanese Floristic Region (SJFR), Yang et al. assess genetic structure and phylogenetic relationships, and reconstruct ancestral sites for Cardiocrinum (Liliaceae), a genus consisting of four taxa distributed across the SJFR. The biogeographic analyses, based on six chloroplast DNA (cpDNA) fragments and three low copy nuclear genes (LCNG), reveal […] More

    Historical refugia and origins of genetic diversity in a Neotropical savanna tree species

    Souza et al. investigate the role of Pleistocene climate changes in driving the geographic distribution and genetic diversity of Dimorphandra mollis, a tree species endemic to the Cerrado, the largest Neotropical savanna and a biodiversity hotspot. Statistical phylogeography, coalescent analyses and ecological niche modelling (ENM) revealed an extensive site of historical refugium across Central Brazil. […] More
