摘要

Different theoretical models of contest behaviour are based on different assumptions about what information is used by the opponents. An approach adopted in many empirical studies has been to test predictions about relationships between 'resource-holding potential' (RHP) and contest duration, to determine whether fighting animals assess information about the opponent's RHP or whether they base their decisions only on what they know about their own RHP. Here we show that these two alternatives cannot be distinguished by analysis of RHP measures and contest duration alone and highlight the need to analyse further parameters of contests such as temporal changes in the intensity of agonistic behaviour.rnContests, where individuals compete aggressively and directly against one another, can be considered ubiquitous across animal taxa. Agonistic behaviours that are used during contests are often the result of sexual selection but can also occur over essential resources other than mates such as food, territory or shelter. Since they rarely involve injuries so severe that one of the opponents is compelled to stop fighting, they are settled in most cases by a decision on the part of one opponent, the loser, to 'give up' orrnwithdraw from the contest.
