“…For example, among socially monogamous species, extrapair paternity or maternity discovered with molecular markers and parentage analysis is commonplace (Westneat & Stewart, 2003). Therefore, genetic analysis of parentage is necessary to characterize the genetic mating system of a population and gain insight into the reproductive strategies of individuals that may otherwise be hidden from observation in field studies (Stephen Yezerinac, 2013).…”

Understanding the mating system and reproductive success of a species provides evidence for sexual selection. We examined the mating system and the reproductive success of captive adult black sea bream (Acanthopagrus schlegelii), using parentage assignment based on two microsatellites multiplex PCR systems, with 91.5% accuracy in a mixed family (29 sires, 25 dams, and 200 offspring). Based on the parentage result, we found that 93.1% of males and 100% of females participated in reproduction. A total of 79% of males and 92% of females mated with multiple partners (only 1 sire and 1 dam were monogamous), indicating that polygynandry best described the genetic mating system of black sea bream. For males, maximizing the reproductive success by multiple mating was accorded with the sexual selection theory while the material benefits hypothesis may contribute to explain the multiple mating for females. For both sexes, there was a significant correlation between mating success and reproductive success and the variance in reproductive success of males was higher than females. Variation in mating success is the greatest determinant to variation in reproductive success when the relationship is strongly positive. The opportunity for sexual selection of males was twice that of females, as well as the higher slope of the Bateman curve in males suggested that the intensity of intrasexual selection of males was higher than females. Thus, male-male competition would lead to the greater variation of mating success for males, which caused greater variation in reproductive success in males. The effective population number of breeders (N b ) was 33, and the N b /N ratio was 0.61, slightly higher than the general ratio in polygynandrous fish populations which possibly because most individuals mated and had offspring with a low variance. The relatively high N b contributes to the maintenance of genetic diversity in farmed black sea bream populations.

“…Although clustering is observed in some smaller shorebird species, the benefits are unclear (Armstrong & Nol, 1993;Fraga & Amat, 1996;Nelson, 2007;Rae et al, 1998). Aggregated nesting in smaller species could provide opportunity for extra-pair copulations, but extra-pair paternity tends to be relatively low in shorebirds and is found primarily in species with low rates of philopatry and mate fidelity (Küpper et al, 2004;Wagner, 1998;Yezerinac et al, 2013). Aggregated nesting is therefore not expected among monogamous and typically territorial calidrine sandpipers (Pitelka et al, 1974).…”

Across avian taxa, the spatial distribution of nests ranges from dispersed and solitary to extremely dense aggregations. Colonial nesting (i.e., aggregated nesting regardless of cooperative behavior; Siegel-Causey & Kharitonov, 1990) has evolved independently several times, yet remains relatively uncommon in birds, occurring in only about 13% of species (Lack, 1968;Rolland et al., 1998), where benefits of breeding in close proximity to conspecifics outweigh potential costs, such as food depletion or increased conspecific brood parasitism (Bonal & Aparicio, 2008;Craik et al., 2018). Benefits of aggregations may include reduced predation due to group defence, increased opportunities for extra-pair copulations, or increased food-finding efficiency (
