Within populations, individuals often show repeatable variation in behaviour, called 'animal
personality'. In the last few decades, numerous empirical studies have attempted to …

In many animal species, males may exhibit one of several discrete, alternative ways of
obtaining fertilisations, known as alternative reproductive tactics (ARTs). Males exhibiting …

Rhythmic stability (nonrandom temporal structure) is required for many neural and
physiological functions, whereas rhythmic irregularities can indicate genetic or …

Lekking is a spectacular mating system in which males maintain tightly organized clustering
of territories during the mating season, and females visit these leks for mating. Various …

Choosing to mate with an infected partner has several potential fitness costs, including
disease transmission and infection-induced reductions in fecundity and parental care. By …

Free‐ranging wild vertebrates need to cope with natural and anthropogenic stressors that
cause short and/or long‐term behavioural and physiological responses. In areas of high …

Costly signaling theory is based on the idea that individuals may signal their quality to
potential mates and that the signal's costliness plays a crucial role in maintaining information …

In chorusing species, conspecific interference exerts strong selection on signal form and
timing to maximize conspicuousness and attractiveness within the signaling milieu. We …

Many studies ask whether young or older males are better at acquiring mates. Even so, how
age affects reproductive success is still poorly understood because male age and mating …

Early developmental nutrition profoundly influences phenotypic trajectories and affects adult
morphology, physiology, behaviour, longevity and fitness across taxa. During early life, the …
