Data from: Evolution of sociability by artificial selection

Andrew M. Scott, Ian Dworkin & Reuven Dukas
There has been extensive research on the ecology and evolution of social life in animals that live in groups. Less attention, however, has been devoted to apparently solitary species even though recent research indicates that they also possess complex social behaviors. To address this knowledge gap, we artificially selected on sociability, defined as the tendency to engage in non-aggressive activities with others, in fruit flies. Our goal was to quantify the factors that determine the...

Mitonuclear interactions and introgression genomics of macaque monkeys (Macaca) highlight the influence of behaviour on genome evolution

Ben Evans
In most macaques, females are philopatric and males migrate from their natal ranges, which results in pronounced divergence of mitochondrial genomes within and among species. We therefore predicted that some nuclear genes would have to acquire compensatory mutations to preserve compatibility with diverged interaction partners from the mitochondria. We additionally expected that these sex-differences would have distinctive effects on gene flow in the X and autosomes. Using new genomic data from 29 individuals from eight...

Data from: Habitat disturbance alters color contrast and the detectability of cryptic and aposematic frogs

James Barnett, Brandon Varela, Ben Jennings, David Lesbarrères, Jonathan Pruitt & David Green
Animals use color both to conceal and signal their presence, with patterns that match the background, disrupt shape recognition, or highlight features important for communication. The forms that these color patterns take are responses to the visual systems that observe them and the environments within which they are viewed. Increasingly, however, these environments are being affected by human activity. We studied how pattern characteristics and habitat change may affect the detectability of three frog color...

Data from: Colour pattern variation forms local background matching camouflage in a leaf-mimicking toad

James Barnett, Constantine Michalis, Nicholas Scott-Samuel & Innes Cuthill
Optimal camouflage can, in principle, be relatively easily achieved in simple, homogeneous, environments where backgrounds always have the same color, brightness, and patterning. Natural environments are, however, rarely homogenous and species often find themselves viewed against varied backgrounds where the task of concealment is more challenging. One result of variable backgrounds is the evolution of intraspecific phenotypic variation which may either be generalized, with multiple similarly cryptic patterns, or specialized, with each discrete color form...

Spatial heterogeneity in resources alters selective dynamics in Drosophila melanogaster

Ian Dworkin, Audrey E Wilson & Ali Siddiqui
Environmental features can alter the behaviours and phenotypes of organisms evolving within them influencing the dynamics of natural and sexual selection. Experimental environmental manipulation, particularly when conducted in experiments where the dynamics of the purging of deleterious alleles are compared, has demonstrated both direct and indirect effects on the strength and direction of selection. However, many of these experiments are conducted with fairly simplistic environments when it is not always clear how or why particular...

16S V4 raw read count data; 16S reads metadata; new MHC class II allele sequences

Leanne Grieves
Pathogen-mediated selection at the major histocompatibility complex (MHC) is thought to promote MHC-based mate choice in vertebrates. Mounting evidence implicates odour in conveying MHC genotype, but the underlying mechanisms remain uncertain. MHC effects on odour may be mediated by odour-producing symbiotic microbes whose community structure is shaped by MHC genotype. In birds, preen oil is the primary source of body odour and similarity at MHC predicts similarity in preen oil composition. Hypothesizing that this relationship...

A long tail of truth and beauty: a simple rule of pattern formation explains symmetry, complexity and beauty in the peacock’s tail

Rama Singh
Darwin’s theory of sexual selection by female choice has become a standard explanation for exaggerated sexually dimorphic traits, such as the peacock’s (Pavo cristatus) long tail. Eyespot beauty-based female choice requires genetic variation in female preference and the number of eyespots, as well as a genetic correlation between the two. However, little genetic variation has been documented in either of these traits in natural and feral peacock populations. We examined the anatomical plan underlying feather...
