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

Although consistent between‐individual differences in behaviour (ie animal personality) are

Sperm competition is thought to impose strong selection on males to produce competitive
ejaculates to outcompete rival males under competitive mating conditions. Our …

Successful reproduction is critical to the persistence of at-risk species; however,
reproductive characteristics are understudied in many wild species. New Zealand's endemic …

The theoretical trade-off between immune and endocrine investment in mating animals has
received mixed empirical support, particularly in reptiles. We investigated the relationship …

When females copulate with multiple males, pre-and post-copulatory sexual selection may
interact synergistically or in opposition. Studying this interaction in wild populations is …

Senescence, the deterioration of organismal function with advancing age, is a puzzling
biological phenomenon. While actuarial senescence (ie, age-dependent increases in …

Managing a species of conservation concern can be best achieved when there is
information on the reproductive physiology of both sexes available; however, many species …

The nestlings of many bird species have ornaments in their mouths, yet the within‐species
