Alpha systems water tank4/28/2023 ![]() ![]() Because larger individuals tend to win contests, we then tested how the maximum performance and endurance of snaps scaled with size.Then, when they fire snaps, they switch to cumulative assessment-a type of self-assessment where contestants endure costs from their own behaviours (e.g. heterochaelis use mutual assessment early in contests. We were specifically interested in the snapping behaviour during which snapping shrimp fire imploding cavitation bubbles-hereafter, ‘snaps’-at their opponents. Then, we used biomechanical measurements of a common contest behaviour to inform how assessment might operate. Here, we performed behavioural contest analyses to determine the assessment strategies used in snapping shrimp ( Alpheus heterochaelis) contests.Functional scaling studies of contest behaviour performance can inform how assessment signals, offensive capacity and endurance scale with RHP and thereby elucidate the mechanisms through which each of these assessment types operates. Contestants forfeit once they ascertain that their opponent has greater resource-holding potential (RHP mutual assessment) or once they reach a threshold of costs (self-assessment). ![]() ![]() ![]() Animals compete in contests over limited resources. ![]()
