Aggressive behavior is important in resource access and determination of fitness in many species. In the rusty crayfish, Orconectes rusticus, limited availability of shelter leads to aggressive bouts of dominance. We tested the effects of reduced territory on crayfish aggression by examining fights in two habitats of different sizes. We found that aggressive behavior was significantly higher when available territory was reduced.
