Abstract

ASSESSMENT GAMES AND COMPETITIVE BEHAVIOUR OF THE MANGROVE TREE-DWELLING CRAB, SELATIUM BROCKII (DE MAN, 1887) (DECAPODA, GRAPSIDAE) BY B. GODSALL 1 ) and I. M. SMALLEGANGE Division of Biology, Imperial College London, Silwood Park, Ascot, SL5 7PY, U.K. ABSTRACT Game theoretical models have been developed to understand the decisions of individuals to continue or stop fighting. These can be split into self assessment models (cumulative assessment model (CAM), war of attrition without assessment (WOA-WA), energetic WOA), where contestants only have information on their own fighting persistence, and mutual assessment models (sequential assessment game: SAM), where contestants exchange information on each other’s competitive ability. Here, we assess if self or mutual assessment occurs in fights between male mangrove tree- dwelling crabs, Selatium brockii (De Man, 1887). Contests were staged in the presence of a female between focal crabs belonging to either of two different absolute size classes against a smaller, size-matched, and larger opponent. In line with mutual assessment models and CAM, contest duration increased when contestants were more matched in competitive ability (i.e., size) but was not significantly different between focal crab sizes.
