Data from: When hawks give rise to doves: the evolution and transition of enforcement strategies

Omar Tonsi Eldakar, Andrew C. Gallup & William Wallace Driscoll
The question of how altruism can evolve despite its local disadvantage to selfishness has produced a wealth of theoretical and empirical research capturing the attention of scientists across disciplines for decades. One feature that has remained consistent through this outpouring of knowledge has been that researchers have looked to the altruists themselves for mechanisms by which altruism can curtail selfishness. An alternative perspective may be that just as altruists want to limit selfishness in the...

Data from: An evaluation of the hybrid speciation hypothesis for Xiphophorus clemenciae based on whole genome sequences

Molly Schumer, Rongfeng Cui, Bastien Boussau, Ronald Brice Walter, Gil G. Rosenthal & Peter Andolfatto
Once thought rare in animal taxa, hybridization has been increasingly recognized as an important and common force in animal evolution. In the past decade, a number of studies have suggested that hybridization has driven speciation in some animal groups. We investigate the signature of hybridization in the genome of a putative hybrid species, Xiphophorus clemenciae, through whole genome sequencing of this species and its hypothesized progenitors. Based on analysis of this data, we find that...

Data from: Accurate measurements of dynamics and reproducibility in small genetic networks

Julien O. Dubuis, Reba Samanta & Thomas Gregor
Quantification of gene expression has become a central tool for understanding genetic networks. In many systems the only viable way to measure protein levels is by immunofluorescence, which is notorious for its limited accuracy. Using the early Drosophila embryo as an example, we show that careful identification and control of experimental error allows for highly accurate gene expression measurements. We generated antibodies in different host species, allowing for simultaneous staining of four Drosophila gap genes...

Data from: Evolution of eye morphology and rhodopsin expression in the Drosophila melanogaster species subgroup

A striking diversity of compound eye size and shape has evolved among insects. The number of ommatidia and their size are major determinants of the visual sensitivity and acuity of the compound eye. Each ommatidium is composed of eight photoreceptor cells that facilitate the discrimination of different colours via the expression of various light sensitive Rhodopsin proteins. It follows that variation in eye size, shape, and opsin composition is likely to directly influence vision. We...

Data from: Detecting genes for variation in parasite burden and immunological traits in a wild population: testing the candidate gene approach

Emily A. Brown, Jill G. Pilkington, Dan H. Nussey, Kathryn A. Watt, Adam D. Hayward, Rachel Tucker, Andrea L. Graham, Steve Paterson, Dario Beraldi, Josephine M. Pemberton & Jon Slate
Identifying the genes underlying phenotypic variation in natural populations can provide novel insight into the evolutionary process. Here we test the candidate gene approach to identifying loci involved in variation in gastrointestinal parasite burden, in a wild population of Soay sheep. A comprehensive literature review, Gene Ontology databases, and comparative genomics resources were used to generate a list of candidate genes. In a pilot study these candidates, along with 50 random genes, were then sequenced...

Data from: Role of grooming in reducing tick load in wild baboons (Papio cynocephalus)

Mercy Y. Akinyi, Susan C. Alberts, Jeanne Altmann, Nilesh B. Patel, Jenny Tung & Maamun Jeneby
Nonhuman primate species spend a conspicuous amount of time grooming during social interactions, a behaviour that probably serves both social and health-related functions. While the social implications of grooming have been relatively well studied, less attention has been paid to the health benefits, especially the removal of ectoparasites, which may act as vectors in disease transmission. In this study, we examined whether grooming behaviour reduced tick load (number of ticks) and haemoprotozoan infection status in...

Data from: Cutting through the complexity of cell collectives

Carey D. Nadell, Vanni Bucci, Knut Drescher, Simon A. Levin, Bonnie L. Bassler & Joao B. Xavier
Via strength in numbers, groups of cells can influence their environments in ways that individual cells cannot. Large-scale structural patterns and collective functions underpinning virulence, tumour growth and bacterial biofilm formation are emergent properties of coupled physical and biological processes within cell groups. Owing to the abundance of factors influencing cell group behaviour, deriving general principles about them is a daunting challenge. We argue that combining mechanistic theory with theoretical ecology and evolution provides a...

Data from: Distinguishing social from nonsocial navigation in moving animal groups

Nikolai W. F. Bode, Daniel W. Franks, A. Jamie Wood, Julius J. B. Piercy, Darren P. Croft & Edward A. Codling
Many animals, such as migrating shoals of fish, navigate in groups. Knowing the mechanisms involved in animal navigation is important when it comes to explaining navigation accuracy, dispersal patterns, population and evolutionary dynamics and consequently the design of conservation strategies. When navigating towards a common target, animals could interact socially by sharing available information directly or indirectly, or each individual could navigate by itself and aggregations may not disperse because all animals are moving towards...
