Large benthic decapods play an increasingly important role in commercial fisheries
worldwide, yet their roles in the marine ecosystem are less well understood. A synthesis of …

Contest theory predicts the evolution of a stable mixture of different strategies for fighting.
Here, we investigate the possibility that stable between-individual differences in startle …

The green crab, Carcinus maenas, is one of the most successful marine invasive species
worldwide. The recent (2007) discovery and rapid explosion of populations of green crab in …

Assessment of their own resource-holding potential (RHP) and that of their opponent affects
the behaviours individuals use in contest competition. Contestants may use their own RHP …

In battles between rival groups, aggression levels, and ultimately the outcome, may be
influenced by the number of individuals and the resource-holding potential (RHP) of the …

The European green crab Carcinus maenas is an invasive species in the northwestern
Atlantic that has the potential to compete and prey upon endemics such as juvenile …

Serracutisoma proximum is a harvestman with alternative male morphs. Large males use
sexually dimorphic second legs in fights for the possession of territories on the vegetation …

We characterized the role of chelae during agonistic encounters of the crayfish Procambarus
