Background Most tropical and subtropical plants are biotically pollinated, and insects are the
major pollinators. A small but ecologically and economically important group of plants …

About 3 million years ago (Ma), the I sthmus of P anama joined the A mericas, forming a land
bridge over which inhabitants of each A merica invaded the other—the G reat A merican B …

Phylogenetic analysis has entered the genomics (multilocus) era. For less experienced
researchers, conquering the large number of software programs required for a multilocus …

In phylogenetic analyses of molecular sequence data, partitioning involves estimating
independent models of molecular evolution for different sets of sites in a sequence …

Background Partitioning involves estimating independent models of molecular evolution for
different subsets of sites in a sequence alignment, and has been shown to improve …

Modern attempts to produce biogeographic maps focus on the distribution of species, and
the maps are typically drawn without phylogenetic considerations. Here, we generate a …

Summary The tropical Andes of South America, the world's richest biodiversity hotspot, are
home to many rapid radiations. While geological, climatic, and ecological processes …

The tempo of species diversification in large clades can reveal fundamental evolutionary
mechanisms that operate on large temporal and spatial scales [1–4]. Hummingbirds have …

We present an integrative model predicting associations among epiphytism, the tank habit,
entangling seeds, C 3 vs. CAM photosynthesis, avian pollinators, life in fertile, moist …
