Experiments with robots explain synchronized courtship in fiddler crabs
نویسندگان
چکیده
surprise that a lowlevel sensorimotor manipulation systematically influences the behavior in a task only implicitly evoking the notion of number magnitude. However, sensory and motor processes, which have originally evolved for basic interactions with the environment, are reportedly exploited during abstract cognition [15]. Intriguingly, as head turning can influence one’s spontaneous spatial exploration, it also appears to affect predictably the apparent spontaneity of ‘random’ numerical choices.

Robotic crabs reveal that female fiddler crabs are sensitive to changes in male display rate
Males often produce dynamic, repetitive courtship displays that can be demanding to perform and might advertise male quality to females. A key feature of demanding displays is that they can change in intensity: escalating as a male increases his signalling effort, but de-escalating as a signaller becomes fatigued. Here, we investigated whether female fiddler crabs, Uca mjoebergi, are sensitive ...
متن کاملKeeping up appearances: male fiddler crabs wave faster in a crowd.
Courtship displays are often energetically and temporally costly as well as highly conspicuous to predators. Selection should therefore favour signalling tactics that minimize courtship costs while maintaining or increasing signal attractiveness. In fiddler crabs, males court females by waving their one greatly enlarged claw in a highly conspicuous and costly display. Here, we investigate wheth...
متن کاملA Spatially Explicit Model of Synchronization in Fiddler Crab Waving Displays
Fiddler crabs (Uca spp., Decapoda: Ocypodidae) are commonly found forming large aggregations in intertidal zones, where they perform rhythmic waving displays with their greatly enlarged claws. While performing these displays, fiddler crabs often synchronize their behavior with neighboring males, forming the only known synchronized visual courtship displays involving reflected light and moving b...
متن کاملEavesdropping in crabs: an agency for lady detection.
Although conspicuous courtship displays are an effective way of attracting the attention of receptive females, they could provide valuable information to rival males on the location of these females. In fiddler crabs, males that see a receptive female wave their single, greatly enlarged claw in a highly conspicuous courtship display. We test whether other males use this courtship display to ale...
متن کاملDoes male reproductive effort increase with age? Courtship in fiddler crabs.
Theory suggests that reproductive effort generally increases with age, but life-history models indicate that other outcomes are possible. Empirical data are needed to quantify variation in actual age-dependence. Data are readily attainable for females (e.g. clutch per egg size), but not for males (e.g. courtship effort). To quantify male effort one must: (i) experimentally control for potential...
