Data from: Clinal variation in seed traits influencing life cycle timing in Arabidopsis thaliana.

Alicia Montesinos-Navarro, F. Xavier Picó & Stephen J. Tonsor
Early life history transitions are crucial determining lifetime survival and fecundity. Adaptive evolution in early life history traits involves a complex interplay between the developing plant and its current and future environments. We examined the plant’s earliest life history traits, dissecting an integrated suite of pre-germination processes: primary dormancy, thermal induction of secondary dormancy, and seasonal germination response. We examined genetic variation in the three processes, genetic correlations among the processes, and the scaling of...

Data from: Evolution of Acoustic and Visual Signals in Asian Barbets

Alejandro Gonzalez-Voyer, Robert-J. Den Tex, Alberto Castelló, Jennifer A. Leonard & R.-J. Den Tex
The study of animal communication systems is an important step towards gaining greater understanding of the processes influencing diversification because signals often play an important role in mate choice and can lead to reproductive isolation. Signal evolution can be influenced by a diversity of factors such as biophysical constraints on the emitter, the signalling environment, or selection to avoid heterospecific matings. Furthermore, because signals can be costly to produce, trade-offs may exist between different types...

Data from: Fractal geometry of a complex plumage trait reveals bird's quality

Lorenzo Pérez-Rodríguez, Roger Jovani & François Mougeot
Animal coloration is key in natural and sexual selection, playing significant roles in intra- and interspecific communication because of its linkage to individual behaviour, genetics and physiology. Simple animal traits such as the area or the colour intensity of homogeneous patches have been profusely studied. More complex patterns are widespread in nature, but they escape our understanding because their variation is difficult to capture effectively by standard, simple measures. Here, we used fractal geometry to...

Data from: Genetic basis of adaptation in Arabidopsis thaliana: local adaptation at the seed dormancy QTL DOG1

Ilkka Kronholm, F. Xavier Picó, Carlos Alonso-Blanco, Jérôme Goudet & Juliette De Meaux
Local adaptation provides an opportunity to study the genetic basis of adaptation and investigate the allelic architecture of adaptive genes. We study DELAY OF GERMINATION 1 (DOG1), a gene controlling natural variation in seed dormancy in Arabidopsis thaliana and investigate evolution of dormancy in 41 populations distributed in four regions separated by natural barriers. Using F_ST and Q_ST comparisons, we compare variation at DOG1 with neutral markers and quantitative variation in seed dormancy. Patterns of...
