There is increasing interest in individual differences in animal behaviour. Recent research
now suggests that an individual's behaviour, once considered to be plastic, may be more …

Contestants are predicted to adjust the cost of a fight in line with the perceived value of the
resource and this provides a way of determining whether the resource has been assessed …

It is well known that non-human animals respond to information encoded in vocal signals,
and the same can be said of humans. Specifically, human voice pitch affects how speakers …

This review discusses body size and mass as they relate to the Orthoptera (crickets,
katydids, grasshoppers) and the Phasmatodea (walkingsticks). It addresses the expression …

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 …

Competition for resources is a ubiquitous feature of life, and a central topic in behavioral
ecology. Organisms use assessment strategies to resolve contests, which can be delineated …

Recently, there has been increasing interest in behavioral syndrome research across a
range of taxa. Behavioral syndromes are suites of correlated behaviors that are expressed …

In animal contests, individuals respond plastically to the phenotypes of the opponents that
they confront. These “opponent”—or “indirect”—effects are often repeatable, for example …

During contests the outcome is ultimately determined by the difference in fighting ability or
resource holding potential (RHP) of opponents and the loser may make the decision to give …
