Game theory models are a useful tool for investigating strategies of conflict resolution between animals Models can be divided into self assessment strategies (energetic war of attrition cumulative assessment model), and mutual assessment strategies (sequential assessment model) Model predictions are based on estimates of resource holding potential ( and differ in their assumptions about how contestants gather information about RHP In Utah, there is a single native crayfish species, the pilose crayfish Pacifastacus gambelii however, little is known of the ecology and behavior of this species P ilose crayfish were once observed in wide ranges across Utah, but since the introduction of the non native virile crayfish Faxonius virilis pilose crayfish have progressively been displaced Using laboratory staged contests, we aimed to test whether higher aggression in the non native virile crayfish could be causing the displacement of native pilose crayfish Additionally, we aimed to test game theory models and determine the conflict resolution style of these two competitors
