Abstract Behavioral changes in fighting and the development of dominance relationships were analyzed in groups of juvenile crayfish (Astacus astacus) using quantitative behavioral techniques. When individuals were placed into an aquarium, the number of agonistic challenges, their mean duration, and maximum intensity reached were high initially but then decreased steadily as the hierarchy developed. In all groups, linear hierarchies emerged which became increasingly stable over time. Winning… 
Modeling the acquisition of social rank in crayfish: winner and loser effects and self-structuring properties
Comparison with empirical data from the formation of social group structure in crayfish indicated a greater importance for loser effects.
Effects of Different Social and Environmental Conditions on Established Dominance Relationships in Crayfish
It is found that rank orders remained stable when conspecifics of smaller or equal size were added to the original pair, suggesting that both dominant and subordinate must be defeated by a larger crayfish in order to destabilize dominance relationships.
Erratum: Effects of fighting decisions on formation and structure of dominance hierarchies (Marine and Freshwater Behaviour and Physiology)
This study linked the decision-making processes that govern dyadic interactions with the emergent properties of hierarchical structures in social groups with an intuitive expectation that resolution of ambiguities in fighting between closely matched opponents promotes the formation of a social hierarchy.
Stability of dominance relationships in crayfish depends on social context
Direct Benefits of Social Dominance in Juvenile Crayfish
The results of these experiments show that the disposition of crayfish to engage in fighting and formation of a dominance hierarchy in a featureless environment serves to determine future access to an emerging resource, thereby entailing greater benefits for animals of higher social rank.
Fighting over burrows: the emergence of dominance hierarchies in the Norway lobster (Nephrops norvegicus)
Dominant Norway lobsters profit from their rank in a social hierarchy by gaining increased access to burrows and by reducing activity outside the shelters as the hierarchy emerges.
Lack of social hierarchy in wintering white-tailed eagles (Haliaeetus albicilla) when scavenging
It is suggested that unstable dominance relationships in white-tailed eagles may result from (a) some attributes of social organization of wintering flocks, (b) the effect of hunger on the outcomes of agonistic interactions masking the true competitive ability of the contestants, and (c) the ontogenetic tendency of young birds to challenge dominant opponents.
Previous Experiences Alter the Outcome of Aggressive Interactions Between Males in the Crayfish, Procambarus Clarkii
Crayfish, Procambarus clarkii, of different size classes were given a series of winning or losing experiences to determine whether this would affect their likelihood of success in subsequent fights, and recent wins or losses did alter the likelihood of an individual winning a subsequent encounter.
Contest Duration and Dynamics are Affected by Body Size in a Potentially Subsocial Crayfish (Crustacea: Decapoda)
Self-assessment explains the contest dynamics of P. brasiliensis, with smaller individuals giving up sooner, probably due to lower energy and time budgets, and smaller individuals had a higher probability of initiating contests with highly aggressive behaviors.
Quantitative Behavioral Techniques for the Study of Crustacean Aggression
Fighting in clawed decapod crustaceans has received considerable attention due to the presence of patent visual displays featuring conspicuous and potentially lethal weapons. General observation


Dominance hierarchies among communally held juvenile lobsters, Homarus americanus
An investigation was conducted to determine the time for establishment of dominance hierarchies, their stability, and their relationship to molting and death of cultured juvenile lobsters, Homarus americanus, to establish a stable four‐rank hierarchy.
Territory acquisition in lizards: II. Establishing social and spatial relationships
Abstract. Juvenile Anolis aeneus lizards were added to patches of microhabitat in the field and observed as they established territories. The outcome of the first encounter per dyad was an excellent
Strategic decisions during agonistic behaviour in the velvet swimming crab, Necora puber (L.)
In natural populations of these crabs, there may not be a close relationship between size and fighting ability and this may promote more direct assessment of factors such as strength, endurance or motivation.
Territory acquisition in lizards. IV. Obtaining high status and exclusive home ranges
We released juvenile Anolis aeneus lizards into vacant patches of habitat in the field and observed as they established territories. Individuals settling in the presence of few competitors obtained

Dominance hierarchies »ere studied during 8 weeks in eight heterosexual captive groups of Oreochromis mossambicus at Ihe unset of sexual maturity. Linearity was assessed for each group on a weekly
The Establishment of Dominance Relationships in the Blue Gourami, Trichogaster Trichopter Us (Pallas)
I. Hierarchical relationships in the blue gourami, T. trichopterus, are characterized by two distinct temporal phases — an ephemeral period of dominance establishment and a period of hierarchical

Aspects of the aggressive and sexual behaviour of alpheus heterochaelis say
Alpheus heterochaelis were collected near Beaufort, N.C. and the intensity of the sound produced by the large claw is positively correlated with claw size, which offers potential cues to the size of an opponent.
