Recent assembly of the Cerrado, a neotropical plant diversity hotspot, by in situ evolution of adaptations to fire
The relative importance of local ecological and larger-scale historical processes in causing differences in species richness across the globe remains keenly debated. To gain insight into these… Expand

Multiple continental radiations and correlates of diversification in Lupinus (Leguminosae): testing for key innovation with incomplete taxon sampling.
Replicate radiations provide powerful comparative systems to address questions about the interplay between opportunity and innovation in driving episodes of diversification and the factors limiting… Expand

The evolutionary history of Mimosa (Leguminosae): toward a phylogeny of the sensitive plants.
PREMISE OF THE STUDY Large genera provide remarkable opportunities to investigate patterns of morphological evolution and historical biogeography in plants. A molecular phylogeny of the species-rich… Expand

Characterization of angiosperm nrDNA polymorphism, paralogy, and pseudogenes.
Many early reports of ITS region (ITS 1, 5.8S, and ITS 2) variation in flowering plants indicated that nrDNA arrays within individuals are homogeneous. However, both older and more recent studies… Expand

Primary Homology Assessment, Characters and Character States
We discuss contrasting approaches to cladistic character definition and thus to cladistic data matrix compilation. The conventional approach considers character states as alternate forms of the “same… Expand

Evolutionary islands in the Andes: persistence and isolation explain high endemism in Andean dry tropical forests
Aim  The tropical Andes are a world biodiversity hotspot. With diverse biomes and dramatic, geologically recent mountain uplift, they offer a system to study the relative contributions of geological… Expand

A new subfamily classification of the leguminosae based on a taxonomically comprehensive phylogeny
The classification of the legume family proposed here addresses the long-known non-monophyly of the traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported… Expand

The ubiquity of alpine plant radiations: from the Andes to the Hengduan Mountains.
Alpine plant radiations are compared across the world's major mountain ranges and shown to be overwhelmingly young and fast, largely confined to the Pliocene and Pleistocene, and some of them… Expand

Metacommunity process rather than continental tectonic history better explains geographically structured phylogenies in legumes.
Penalized likelihood estimated ages of both densely sampled intracontinental and sparsely sampled transcontinental crown clades in the legume family show a mostly Quaternary to Neogene age… Expand

From famine to feast? Selecting nuclear DNA sequence loci for plant species-level phylogeny reconstruction
Phylogenetic analyses of DNA sequences have prompted spectacular progress in assembling the Tree of Life. However, progress in constructing phylogenies among closely related species, at least for… Expand
