Data from: Vertebral evolution and the diversification of squamate reptiles

Philip J. Bergmann & Duncan J. Irschick
Taxonomic, morphological and functional diversity are often discordant and independent components of diversity. A fundamental and largely unanswered question in evolutionary biology is why some clades diversify primarily in some of these components and not others. Dramatic variation in trunk vertebral numbers (14 to >300) among squamate reptiles coincides with different body shapes, and snake-like body shapes have evolved numerous times. However, whether increased evolutionary rates or numbers of vertebrae underlie body shape and taxonomic...

PREMISE OF THE STUDY: Weeds cause considerable environmental and economic damage. However, genomic characterization of weeds has lagged behind that of model plants and crop species. Here we report on the development of genomic tools and resources for 11 weeds from the Compositae family that will serve as a basis for subsequent population and comparative genomic analyses. Because hybridization has been suggested as a stimulus for the evolution of invasiveness, we also analyze these genomic...

Data from: Exploring possible human influences on the evolution of Darwin's finches

Luis Fernando De León, Joost A.M. Raeymaekers, Eldredge Bermingham, Jeffrey Podos, Anthony Herrel & Andrew P. Hendry
Humans are an increasingly common influence on the evolution of natural populations. Potential arenas of influence include altered evolutionary trajectories within populations and modifications of the process of divergence among populations. We consider this second arena in the medium ground finch (Geospiza fortis) on Santa Cruz Island, Galápagos, Ecuador. Our study compared the G. fortis population at a relatively undisturbed site, El Garrapatero, to the population at a severely disturbed site, Academy Bay, which is...

Data from: Population genomics of wild and laboratory zebrafish (Danio rerio)

Andrew R Whiteley, Anuradha Bhat, Emilia P Martins, Richard L Mayden, M Arunachalam, Silva Uusi-Heikkilä, A.T.A. Ahmed, Jiwan Shrestha, Matthew Clark, Derek Stemple & Louis Bernatchez
Understanding a wider range of genotype-phenotype associations can be achieved through ecological and evolutionary studies of traditional laboratory models. Here, we conducted the first large-scale geographic analysis of genetic variation within and among wild zebrafish (Danio rerio) populations occurring in Nepal, India, and Bangladesh and we genetically compared wild populations to several commonly used lab strains. We examined genetic variation at 1,832 polymorphic EST-based SNPs and the cytb mitochondrial gene in 13 wild populations and...

Data from: Constraint and opportunity: the genetic basis and evolution of modularity in the cichlid mandible

Kevin J. Parsons, Eladio Márquez & R. Craig Albertson
Modular variation, whereby the relative degree of connectivity varies within a system, is sometimes thought to evolve through natural selection. In this way, modularity may facilitate evolution. Alternatively, conserved patterns of modularity may act to constrain evolution by preventing certain functions from evolving. A comprehensive understanding of the interplay between these phenomena will require knowledge of both the inheritance and genetic basis of modularity. Here we explore these ideas in the cichlid mandible by investigating...
