Oxidative stress may be of profound biological relevance. In this Commentary, I discuss
some key issues faced by the emerging field of oxidative stress ecology, and seek to provide …

In this review, it is our aim 1) to describe the high diversity in molecular and structural
antioxidant defenses against oxidative stress in animals, 2) to extend the traditional concept …

Research programmes on oxidative stress and hormesis are wide ranging. Biomedical and
toxicological sciences have traditionally centralised such research, but in the last years we …

The idea that resources are limited and animals can maximise fitness by trading costly
activities off against one another forms the basis of life-history theory. Although investment in …

Mechanisms maintaining honesty of sexual signals are far from resolved, limiting our
understanding of sexual selection and potential important parts of physiology. Carotenoid …

Recent ecological studies have shown that oxidative status could have a significant impact
on fitness components in wild animals. Not only can oxidative status reflect the …

The continuing viability of the free‐radical theory of ageing has been questioned following
apparently incompatible recent results. We show by modelling positional effects of the …

Sexual selection arises from competition among individuals for access to mates, resulting in
the evolution of conspicuous sexually selected traits, especially when inter‐sexual …

The extent to which early stress exposure is detrimental to Darwinian fitness may depend on
its severity, with mild stress exposure actually having a stimulatory and, possibly, beneficial …

Group living is predicted to arise only when the fitness benefits outweigh the costs of
sociality. Group-living species—including cooperatively breeding and family-living birds and …
