Data from: Molecular evolution of shattering loci in U.S. weedy rice

Carrie Thurber, Michael Reagon, Briana Gross, Kenneth Olsen, Yulin Jia & Ana Caicedo
Cultivated rice fields worldwide are plagued with weedy rice, a conspecific weed of cultivated rice (Oryza sativa L.). The persistence of weedy rice has been attributed, in part, to its ability to shatter (disperse) seed prior to crop harvesting. In the United States, separately evolved weedy rice groups have been shown to share genomic identity with exotic domesticated cultivars. Here, we investigate the shattering phenotype in a collection of U.S. weedy rice accessions, as well...

Data from: Modularity and scaling in fast movements: power amplification in mantis shrimp

Thomas Claverie, Elliot Chan & Sheila N. Patek
Extremely fast animal actions are accomplished with mechanisms that reduce the duration of movement. This process is known as power amplification. While many studies have examined the morphology and performance of power-amplified systems, little is known about their development and evolution. Here we examine scaling and modularity in the powerful predatory appendages of a mantis shrimp, Gonodactylaceus falcatus (Crustacea, Stomatopoda). We propose that power-amplified systems can be divided into three units: an engine (e.g., muscle),...

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...
