“…Observational studies of other fiddler species also suggest that courtship effort increases with size (e.g. in Uca pugilator, larger males feed less and wave more often) [13]. One 'proximate' explanation for our finding is that larger males might more strongly stimulate neighbours to wave, which then stimulates the focal male to wave more himself.…”

“…Waving is energetically costly [11] and related to body condition [12]. Observational studies have investigated the relationship between male size and sexual display in some fiddler species [13,14], but age-dependent courtship has not been explicitly addressed. We experimentally standardized female presence to determine how male age/size is related to: (i) the likelihood of initiating courtship; (ii) courtship rate; (iii) courtship persistence; and (iv) the effect of female size on male courtship.…”

Does male reproductive effort increase with age? Courtship in fiddler crabs

et al. 2013

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 age-dependent changes in female presence; and, crucially, (ii) distinguish between the likelihood of courtship being initiated, the display rate, and the total time invested in courting before stopping ('courtship persistence'). We provide a simple experimental protocol, suitable for many taxa, to illustrate how to obtain this information. We studied courtship waving by male fiddler crabs, Uca annulipes. Given indeterminate growth, body size is correlated with age. Larger males were more likely to wave at females and waved more persistently. They did not, however, have a higher courtship rate (waves per second). A known female preference for males with higher display rates explains why, once waving is initiated, all males display at the same rate.

“…Whereas small males can quickly reach T b 's and desiccation levels detrimental to physiological performance, larger males approach those limits more slowly. Hyatt (1977) observed that large reproductively-active male U. pugilator spent less time in their burrows than small individuals and suggested that this might be due to reduced tolerance to thermal and desiccation stresses of small crabs. Our data are consistent with this hypothesis.…”

“…Both immediately before and after chasing a female, the male often performs a waving display (Moriito and Wada 1997). Waving may facilitate capturing a female by inducing her to approach him, as suggested in U. pugilator (Hyatt 1977), or by causing her to stop before running away, as hypothesized by Land and Layne (1995). No data are available, however, to show how female S. globosa respond to male waving.…”

Scopimera globosa, a small ocypodid crab, rhythmically raises and lowers its body and both chelae in a waving display when it is not interacting directly with another individual. To determine whether waving is a social signal and to deduce its possible function, we manipulated the sex and density of crabs in a field enclosure and recorded the waving frequency of males. Males with abundant female neighbors waved significantly more often than when the same males were caged with abundant male neighbors. Males caged with fewer neighbors of either sex seldom waved. Thus, males waved most in the presence of females, especially at high density, and least in the presence of other males, suggesting that waving may function in female acquisition.
