Data from: A general description of additive and non-additive elements of sperm competitiveness and their relation to male fertilization success

Leif Engqvist
A complete understanding of male reproductive success, and thus sexual selection, often requires an insight into male success in sperm competition. Genuine conclusions on male sperm competitiveness can only be made in real competitive situations. However, statistical analyses of sperm competitiveness from fertilization success data have been shown to be problematic. Here, I first outline a comprehensive general description of the different additive and non-additive elements relevant for the outcome of sperm competition staged between...

Data from: Sex chromosome linked genetic variance and the evolution of sexual dimorphism of quantitative traits

Arild Husby, Holger Schielzeth, Wolfgang Forstmeier, Lars Gustafsson & Anna Qvarnström
Theory predicts that sex chromsome linkage should reduce intersexual genetic correlations thereby allowing the evolution of sexual dimorphism. Empirical evidence for sex linkage has come largely from crosses and few studies have examined how sexual dimorphism and sex linkage are related within outbred populations. Here we use data on an array of different traits measured on over 10,000 individuals from two pedigreed populations of birds (collared flycatcher and zebra finch) to estimate the amount of...

Data from: Fine-scale spatiotemporal patterns of genetic variation reflect budding dispersal coupled with strong natal philopatry in a cooperatively breeding mammal

Hazel J. Nichols, Neil R. Jordan, Gabriel A. Jamie, Michael A. Cant & Joseph I. Hoffman
The relatedness structure of animal populations is thought to be a critically important factor underlying the evolution of mating systems and social behaviours. While previous work has shown that population structure is shaped by many biological processes, few studies have investigated how these factors vary over time. Consequently, we explored the fine-scale spatiotemporal genetic structure of an intensively studied population of cooperatively breeding banded mongooses (Mungos mungo) over a ten-year period. Overall population structure was...
