Estimating the genetic basis of quantitative traits can be tricky for wild populations in natural
environments, as environmental variation frequently obscures the underlying evolutionary …

Male‐biased sexual size dimorphism (SSD) in mammals has been explained by sexual
selection favouring large, competitive males. However, new research has identified other …

This book presents the first unified conceptual and statistical framework for understanding
the evolution of reproductive strategies. Using the concept of the opportunity for sexual …

2.1 Background Exhaustive empirical surveys have shown that, almost without exception,
macroparasites (parasitic helminths and arthropods) are aggregated across their host …

Competition for fertile females determines male reproductive success in many species. The
priority of access model predicts that male dominance rank determines access to females …

In many animals, variance in male mating success is strongly correlated with male
dominance rank or some other measure of fighting ability. Studies in primates, however …

Unlike most other large mammals, the Soay sheep population of Hirta in the St. Kilda
archipelago show persistent oscillations, sometimes increasing or declining by more than …

Although mating systems and sexual selection have been intensively studied in ungulate
model systems, very few studies have combined genetic paternity analysis with individual …

Behavioural ecology is currently undergoing a paradigm shift, with the traditional concepts of
the choosy, monogamous female and the coadapted gene complex increasingly giving way …

In mammals, high dominance rank among males is often associated with mating success.
However, mating opportunities do not automatically translate into offspring production; …
