Disjunctive distributions across paleotropical regions in the Indian Ocean Basin (IOB) often
invoke dispersal/vicariance debates. Exacum (Gentianaceae, tribe Exaceae) species are …

Aim The biogeographical patterns and drivers of diversity on oceanic islands in the tropical
South Pacific (TSP) are synthesized. We use published studies to determine present …

The equilibrium theory of island biogeography (ETIB) was developed around the concept of
islands formed de novo, with species colonizing and over time reaching a balance between …

The Begoniaceae consist of two genera, Begonia, with approximately 1400 species that are
widely distributed in the tropics, and Hillebrandia, with one species that is endemic to the …

• Premise of the study: The Chamaesyce clade of Euphorbia is the largest lineage of C4
plants among the eudicots, with 350 species including both narrow endemics and …

Adaptive radiation is an evolutionary process that has been promulgated in some clades as
an explanation for species richness and disparity in morphological forms across ecological …

Aim We still have limited understanding of the contingent and deterministic factors that have
fostered the evolutionary success of some species lineages over others. We investigated …

Sequences of internal transcribed spacers (ITS) of nuclear ribosomal DNA, the chloroplast
ndhF gene, and chloroplast trnL-F regions (trnL intron, and trnL [UAA] 3′ exon-trnF [GAA] …

Systematic and biogeographical relationships within the Hawaiian clade of the pantropical
understory shrub genus Psychotria (Rubiaceae) were investigated using phylogenetic …

Aim Pacific biogeographical patterns in the widespread plant genus Melicope JR Forst. & G.
Forst.(Rutaceae) were examined by generating phylogenetic hypotheses based on …
