Data from: The rate and effects of spontaneous mutation on fitness traits in the social amoeba, Dictyostelium discoideum

David W. Hall, Sara Fox, Joan E. Strassman, David C. Queller, Joan E. Strassmann & Jennie J. Kuzdzal-Fick
We performed a mutation accumulation (MA) experiment using the social amoeba Dictyostelium discoideum to estimate the rate and distribution of effects of spontaneous mutations affecting eight putative fitness traits. We found that the per generation mutation rate for most fitness components is 0.0019 mutations per haploid genome per generation, or larger. This rate is an order of magnitude higher than estimates for fitness components in the unicellular eukaryote Saccharomyces cerevisiae, even though the base-pair substitution...

Data from: Macaque monkeys perceive the flash lag illusion

Manivannan Subramaniyan, Alexander S. Ecker, Philipp Berens & Andreas S. Tolias
Transmission of neural signals in the brain takes time due to the slow biological mechanisms that mediate it. During such delays, the position of moving objects can change substantially. The brain could use statistical regularities in the natural world to compensate neural delays and represent moving stimuli closer to real time. This possibility has been explored in the context of the flash lag illusion, where a briefly flashed stimulus in alignment with a moving one...

Data from: Parsimonious inference of hybridization in the presence of incomplete lineage sorting

Yun Yu, Robert Matthew Barnett & Luay Nakhleh
Hybridization plays an important evolutionary role in several groups of organisms. A phylogenetic approach to detect hybridization entails sequencing multiple loci across the genomes of a group of species of interest, reconstructing their gene trees, and taking their differences as indicators of hybridization. However, methods that follow this approach mostly ignore population effects, such as incomplete lineage sorting (ILS). Given that hybridization occurs between closely related organisms, ILS may very well be at play and,...

Data from: Genetic composition of social groups influences male aggressive behaviour and fitness in natural genotypes of Drosophila melanogaster

Julia B. Saltz
Indirect genetic effects (IGEs) describe how an individual’s behaviour—which is influenced by his or her genotype—can affect the behaviours of interacting individuals. IGE research has focused on dyads. However, insights from social networks research, and other studies of group behaviour, suggest that dyadic interactions are affected by the behaviour of other individuals in the group. To extend IGE inferences to groups of three or more, IGEs must be considered from a group perspective. Here, I...
