The current high islands of the Hawaiian archipelago are among the most remote land
masses in the world. They lie 3500 km from California, the nearest continental source, and …

Aim Little is known about how diversification occurs within long‐lived, highly dispersible and
continuously distributed groups. We examined the distribution of genetic variation within the …

The evolutionary origins of the morphological and taxonomic diversity of angiosperms is
poorly known. We used the genus Melianthus to explore the diversification of the southern …

The evolutionary divergence of island populations, and in particular the tempo and relative
importance of neutral and selective factors, is of central interest to the study of speciation …

Natural systems composed of closely related taxa that vary in the degree of phenotypic
divergence and geographic isolation provide an opportunity to investigate the rate of …

The highlands of Mesoamerica harbour some of the highest biodiversity in the world,
especially in cloud forests, but the landscape drivers of this diversification are not well …

We describe range-wide phylogeographic variation in gray jays (Perisoreus canadensis), a
boreal Nearctic corvid that occurs today primarily in recently glaciated regions. Phylogenetic …

With its large size, complex topography and high number of avian endemics, Hispaniola
appears to be a likely candidate for the in situ speciation of its avifauna, despite the …

The" Alpine Ranunculi of New Zealand" are a monophyletic group of species distributed
between the New Zealand alps, Australian alps, and the subantarctic Campbell and …

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