Adult sex ratios: causes of variation and implications for animal and human societies
Converging lines of inquiry from across the social and biological sciences target the adult
sex ratio (ASR; the proportion of males in the adult population) as a fundamental population …

The impact of small groups on pre‐and postcopulatory sexual selection in polyandrous populations
GC McDonald - Ecology and Evolution, 2023 - Wiley Online Library

Mate sampling behavior determines the density dependence of sexual selection
Abstract Theory predicts that the strength of sexual selection (ie, how well a trait predicts
mating or fertilization success) should increase with population density, yet empirical …

[PDF][PDF] Sex ratio affects sexual selection against mutant alleles in a locus-specific way
Higher male: female operational sex ratio (OSR) is often assumed to lead to stronger sexual
