Data from: Poison frog colors are honest signals of toxicity, particularly for bird predators

Martine E. Maan & Molly E. Cummings
Antipredator defenses and warning signals typically evolve in concert. However, the extensive variation across taxa in both these components of predator deterrence, and the relationship between them, are poorly understood. Here we test whether there is a predictive relationship between visual conspicuousness and toxicity levels across 10 populations of the color polymorphic strawberry poison frog, Dendrobates pumilio. Using a mouse-based toxicity assay, we find extreme variation in toxicity between frog populations. This variation is significantly...

Data from: Candidate genes for colour and vision exhibit signals of selection across the pied flycatcher (Ficedula hypoleuca) breeding range

Paula K. Lehtonen, Toni Laaksonen, Aleksandr V. Artemyev, Eugen Belskii, Paul R. Berg, Christiaan Both, Laura Buggiotti, Stanislav Bureš, Malcolm D. Burgess, Andrey V. Bushuev, Indrikis Krams, Juan Moreno, Marko Mägi, Andreas Nord, Jaime Potti, Pierre-Alain Ravussin, Glenn Peter Sætre, Paivi Sirkiä, Wolfgang Winkel & Craig R. Primmer
The role of natural selection in shaping adaptive trait differentiation in natural populations has long been recognized. Determining its molecular basis, however, remains a challenge. Here, we search for signals of selection in candidate genes for colour and its perception in a passerine bird. Pied flycatcher plumage varies geographically in both its structural and pigment-based properties. Both characteristics appear to be shaped by selection. A single-locus outlier test revealed two of fourteen loci to exhibit...

Data from: Phenotypic assortment mediates the effect of social selection in a wild beetle population

Vincent A. Formica, Joel W. McGlothlin, Corlett Wolfe Wood, Malcolm E. Augat, R. Eileen Butterfield, Mollie E. Barnard &
Social interactions often have major fitness consequences, but little is known about how specific interacting phenotypes affect the strength of natural selection. Social influences on the evolutionary process can be assessed using a multilevel selection approach that partitions the effects of social partner phenotypes on fitness (referred to as social or group selection) from those of the traits of a focal individual (nonsocial or individual selection). To quantify the contribution of social selection to total...

Data from: Genetic components to caste allocation in a multiple-queen ant species

Romain Libbrecht, Tanja Schwander & Laurent Keller
Reproductive division of labor and the coexistence of distinct castes are hallmarks of insect societies. In social insect species with multiple queens per colony, the fitness of nestmate queens directly depends on the process of caste allocation (i.e., the relative investment in queen, sterile worker and male production). The aim of this study is to investigate the genetic components to the process of caste allocation in a multiple-queen ant species. We conducted controlled crosses in...
