We performed a field experiment to investigate the effect of carapace width, major cheliped length and burrow ownership on the fighting success of male fiddler crabs (Uca annulipes). We removed males from their burrows and released them back into the colony (n = 82). Released males tended to initiate encounters with burrow owners slightly smaller than themselves. Several general predictions of Sequential Assessment Game models of contest behaviour were supported: (1) residents won more…

The assessment game in sand fiddler crab contests for breeding burrows
Abstract The single enlarged claw of male sand fiddler crabs, Uca pugilator , is used in contests for control of breeding burrows. The larger of the two contestants has the larger claw and usually
Variation in courtship rate in the fiddler crab Uca annulipes: is it related to male attractiveness?
It is suggested that smaller males invest disproportionately more in courtship later in die cycle because die potential benefits are greater due to their increased attractiveness to females (differential benefits).
Performance capacity of fiddler crab males with regenerated versus original claws and success by claw type in territorial contests
Within a western Atlantic salt marsh, regenerated claws are less massive and operate at reduced mechanical efficiency relative to original claws, suggesting a less powerful weapon.
Effect of residence and size asymmetries upon the agonistic interactions between juvenile white-seabream (Diplodus sargus cadenati de la Paz, Bauchot and Daget, 1974)
The behavioural patterns of juvenile white-seabream suggest that asymmetry in residence is an important factor governing the outcome of contest between individuals of this species, and fight intensity and size asymmetry were significant.
Fighting in fiddler crabs Uca mjoebergi: what determines duration?
Temporal constraints and female preference for burrow width in the fiddler crab, Uca mjoebergi
It is proposed that females are selecting burrows to influence incubation rate and ensure timely release of their larvae by selecting specific burrows in which to incubate their clutches.
High motivation enables smaller contestants to win the contests in fiddler crabs (Brachyura, Ocypodidae)
This study shows that longer fighting duration or high motivation enables the smaller contestants, especially the residents, to overcome their inferior fighting ability and win contests against larger opponents.
The Effects of Residency and Body Size on Contest Initiation and Outcome in the Territorial Dragon, Ctenophorus decresii
This study examined the complex contest behaviour of the tawny dragon, a territorial agamid lizard, with the specific aim of defining the factors that determine contest outcome.


The fighting tactics of male mouthbrooding cichlids: the effects of size and residency
Behavioural differences between Winners and losers were found in all types of contest, but the activities that differed between winners and losers of contests settled by size were not the same as those that differ between contestants in fights settled on a residency asymmetry.
Escalated damselfly territorial contests are energetic wars of attrition
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.

Assessment of energy reserves by damselflies engaged in aerial contests for mating territories
A model that assumes an asymptotic increase in flight performance with increasing fat content is proposed to explain the simultaneous effects of relative and absolute fat content on contest duration, and to examine possible mechanisms that damselflies use to assess each other's energy reserves.
Effects of body size on agonistic encounters between male jumping spiders (Araneae: Salticidae)
. Agonistic encounters were staged between males of the jumping spider Zygoballus rufipes to study the relationship between body size (as estimated by weight) and encounter duration, intensity and
Combat in the Fiddler Crabs Uca Pugilator and U. Pugnax: a Quantitative Analysis
Differences between the species in the tempo and length of fights were observed, and an hypothesis, based upon habitat differences and the value of burrows as a resource, is presented to account for these differences.
Time constraints and multiple choice criteria in the sampling behaviour and mate choice of the fiddler crab, Uca annulipes
It is suggested that the number of males sampled (and other indices of ‘‘sampling effort’’) may not be reliable indicators of female choosiness and may not reflect the strength of female mating preferences under certain conditions.
