“…Also in other fishes, females may compete for access to males when the OSR is female‐biased (e.g. threespined stickleback: Li and Owings 1978, seahorses: Vincent 1994, pipefish: Vincent et al 1994).…”

According to current theory a higher level of malemale competition is expected when the OSR is more male-biased as compared to when it is less male-biased.…”

One of the most important factors shaping animal sex‐roles is the operational sex ratio, since a skew of this ratio promotes mating competition in the more abundant sex. In this study, we wanted to see if a change in sex‐roles, related to an environmental induced change in operational sex ratio, could be demonstrated in a field situation. Common goby (Pomatoschistus microps) males build nests under bivalve shells and provide exclusive parental care. Therefore, available nest sites are crucial for successful breeding in this species and should also affect the operational sex ratio. We addressed the question of whether the availability of nest sites, through an effect on the operational sex ratio, affects courtship and mating competition in the common goby. We increased nest site availability in the field by adding potential nest material (bivalve shells) to one location. We then compared the reproductive behaviour of the gobies at this and another location with lower nest site abundance. In general, the reproductive behaviour differed as predicted. Under nest shortage, males occupied new nests and received eggs faster than under nest excess. Behavioural observations of nests revealed that males initiated courtship more often than females where nest sites were abundant, whereas female courtship dominated where nests were scarce. Males more often rejected females attempting to enter their nests under nest shortage, male sneaking attempts were also more common in this bay. Male‐male aggression was frequent at both locations, whereas agonistic interactions between females only occurred in the nest shortage bay. Thus, males should be subject to sexual selection in both bays even though courtship roles differed. These results suggest that nest site availability affects mating competition and courtship roles in the common goby.

“…The threespine stickleback (Gasterosteus aculeatus) has been a workhorse of fish behavioral ecology, and males of this species engage in numerous parasitic tactics (Mori 1995). Most common in G. aculeatus are sneaky fertilizations and egg thievery, behaviors often grouped under the collective term "nest-raiding" (Li and Owings 1978).…”

A Microsatellite Assessment of Sneaked Fertilizations and Egg Thievery in the Fifteenspine Stickleback

Attempts by males to steal fertilizations from other males are common in many species. In some sticklebacks, males also are known to steal eggs from the nests of rivals and to carry them back to their own nests. However the genetic consequences of these nest-raiding behaviors seldom have been investigated. Here we assess genetically the prevalence of sneaked fertilizations and egg stealing, and we describe the mating system in a natural population of the fifteenspine stickleback. Six microsatellite markers were developed and employed to assay a total of 1307 embryos from 28 nests. Guardian males and all nest-holding males in the local area also were genotyped for two to six loci Analysis of male genotypes and those of embryos revealed that five of the 28 nests (18%) contained progeny from sneaked fertilizations, and that four of the 24 nests (17%) with resident males contained stolen egg clutches Comparisons of the composite DNA genotypes of nest-holding males against those of inferred sneakers implicated one nest holder as the sneaker of a nest seven meters from his own. Also, the genetic data demonstrated that nests of males frequently contain eggs from multiple females. The multilocus genotypes of inferred mothers indicated that females mate with multiple males, sometimes over distances greater than one kilometer.
