Dishonest signalling in a fiddler crab
Animal communication theory predicts that low–frequency cheating should be common in generally honest signalling systems. However, perhaps because cheats are designed to go undetected, there are fewExpand

Estimating genetic benefits of polyandry from experimental studies: a meta‐analysis
The consequences of polyandry for female fitness are controversial. Sexual conflict studies and a meta‐analysis of mating rates in insects suggest that there is a longevity cost when females mateExpand

Hiding behaviour in fiddler crabs: how long should prey hide in response to a potential predator?
Abstract Do predator–prey ‘waiting games’ where prey hide from potential predators have inherently unstable evolutionary outcomes, making it impossible to generate quantitative predictions aboutExpand

Fighting in fiddler crabs Uca mjoebergi: what determines duration?
Contest duration in animals is often interpreted as being a consequence of mutual assessment of the difference in the competitors' resource-holding potential (RHP), allowing the inferior individualExpand

A conspicuous courtship signal in the fiddler crab Uca perplexa: female choice based on display structure
The fiddler crab Uca perplexa has a conspicuous male courtship signal that is directed at females to attract them to the male’s burrow for mating. The signal involves waving the unflexed large clawExpand

Attractiveness of sand hoods built by courting male fiddler crabs, Uca musica: test of a sensory trap hypothesis
Courting male fiddler crabs, Uca musica, sometimes build sand hoods at the entrances of their burrows to which they attract females for mating. On average, females visit 17 males in as many minutesExpand

Male-biased predation of a fiddler crab
Great-tailed grackles, Quiscalus mexicanus, prey on fiddler crabs, Uca beebei, either by running straight at them or by running past them then angling sharply back to strike. Grackles that usedExpand

What are the consequences of being left-clawed in a predominantly right-clawed fiddler crab?
Male fiddler crabs (genus Uca) have an enlarged major claw that is used during fights. In most species, 50% of males have a major claw on the left and 50% on the right. In Uca vocans vomeris,Expand

Can beggars be choosers? Male mate choice in a fiddler crab
In most species the operational sex ratio is male biased, so females can be choosy when selecting a mate. Male choosiness, however, may also be beneficial, especially in species where female qualityExpand

Polyandry occurs because females initially trade sex for protection
In many species, females mate with multiple males, suggesting that polyandry confers fitness-enhancing benefits. The benefits of polyandry are usually attributed to either the cumulative acquisitionExpand
