Data from: The evolution of morphological diversity in continental assemblages of Passerine birds

Knud Andreas Jønsson, Jean Philippe Lessard, Robert E. Ricklefs & Jean-Philippe Lessard
Understanding geographic variation in the species richness and lineage composition of regional biotas is a long standing goal in ecology. Why do some evolutionary lineages proliferate while others do not, and how do new colonists fit into an established fauna? Here, we analyse the morphological structure of assemblages of passerine birds in four biogeographic regions to examine the relative influence of colonization history and niche-based processes on regional communities of passerine birds. Using morphological traits...

Data from: Allopolyploidy, diversification, and the Miocene grassland expansion

The role of polyploidy, particularly allopolyploidy, in plant diversification is a subject of debate. Whole-genome duplications precede the origins of many major clades (e.g., angiosperms, Brassicaceae, Poaceae), suggesting that polyploidy drives diversification. However, theoretical arguments and empirical studies suggest that polyploid lineages may actually have lower speciation rates and higher extinction rates than diploid lineages. We focus here on the grass tribe Andropogoneae, an economically and ecologically important group of C4 species with a high...

Data from: Color vision varies more among populations than among species of live-bearing fish from South America

Benjamin A. Sandkam, C. Megan Young, Frances Margaret Walker Breden, Godfrey R. Bourne & Felix Breden
Background: Sensory Bias models for the evolution of mate preference place a great emphasis on the role of sensory system variation in mate preferences. However, the extent to which sensory systems vary across- versus within-species remains largely unknown. Here we assessed whether color vision varies in natural locations where guppies (Poecilia reticulata) and their two closest relatives, Poecilia parae and Poecilia picta, occur in extreme sympatry and school together. All three species base mate preferences...
