For almost 40 years, studies of whole-organism performance have formed a cornerstone of
evolutionary physiology. Although its utility as a heuristic guide is beyond question, and we …

In many species that fight over resources, individuals use specialized structures to gain a
mechanical advantage over their rivals during contests (ie weapons). Although weapons are …

Bite forces play a key role in animal ecology: they affect mating behaviour, fighting success,
and the ability to feed. Although feeding habits of arthropods have a significant ecological …

An animal's movement speed affects all behaviors and underlies the intensity of an activity,
the time it takes to complete it, and the probability of successfully completing it, but which …

Mantis shrimp strike with extreme impact forces that are deadly to prey. They also strike
conspecifics during territorial contests, yet theoretical and empirical findings in aggressive …

Brilliantly-colored birds are a model system for research into evolution and sexual selection.
Red, orange, and yellow carotenoid-colored plumages have been considered honest …

Weapons used in combat between males are usually attributed to sexual selection, which
operates via a fitness advantage for males with weapons of better 'quality'. Because the …

Just as evolutionary biologists endeavour to link phenotypes to fitness, sport scientists try to
identify traits that determine athlete success. Both disciplines would benefit from …

1. Signals used during male combat are expected to be honest indicators of fighting ability.
However, recent studies show that dishonesty in male signalling is more prevalent than …
