Mating systems are a central component in the evolution of animal life histories and in conservation genetics. The patterns of male reproductive skew and of paternal shares in batches of offspring, for example, affect genetic effective population size. A prominent characteristic of mating systems of sea turtles seem to be a considerable intra‐ and interspecific variability in the degree of polyandry. Because of the difficulty of observing the mating behaviour of sea turtles directly in the open…

Strong male-biased operational sex ratio in a breeding population of loggerhead turtles (Caretta caretta) inferred by paternal genotype reconstruction analysis

The results suggest that the operational sex ratio is male-biased at this site and that each male contributed to no more than a single clutch over the 3-year sampling period.

High incidence of multiple paternity in an Australian snapping turtle (Elseya albagula)

This work uses seven polymorphic microsatellite markers to investigate the presence of multiple fathers within clutches from the white-throated snapping turtle (Elseya albagula), an Australian species of conservation concern, and provides the first example of multiple paternity in the Chelidae.

Seasonal monogamy and multiple paternity in a wild population of a territorial reptile (tuatara)

The behavioural and genetic results revealed complexities in female mating patterns that support the potential for cryptic female choice or sperm competition, and warrants further experimental investigation into the mechanisms underlying reptile fertilization and the disparities between social and genetic polyandry in wild populations.

Paternal genotype reconstruction reveals multiple paternity and sex ratios in a breeding population of leatherback turtles (Dermochelyscoriacea)

The feasibility of using male genotype reconstruction to characterize the male component of this breeding population and to assess operational sex ratios for breeding sea turtles is demonstrated.

Mate Selection Based on Genetic Relatedness of Loggerhead Turtles in Captivity

The most parsimonious explanation is that loggerhead turtles in the tank tend to prefer their mate(s) according to genetic relatedness but that the extent of female mate selection and the relationship betweenmate selection and fitness still remain debatable.

Detection of multiple paternity in the Kemp's ridley sea turtle with limited sampling

It is concluded here that female Kemp's ridleys, Lepidochelys kempi, are polyandrous, and this analysis rejected mutation as the sole cause of multiple paternal alleles.

Multiple paternity and female-biased mutation at a microsatellite locus in the olive ridley sea turtle (Lepidochelys olivacea)

Inferred allele-specific mutation rates for Ei8 and expected numbers of mutations per clutch confirmed that maternal alleles for E i8 are more likely to mutate in the olive ridley sea turtle than paternal alleles.

Multiple paternity in loggerhead turtle (Caretta caretta) nests on Melbourne Beach, Florida: a microsatellite analysis

Examination of fine‐scale population structure and paternal contribution to loggerhead clutches on Melbourne Beach, FL, USA using microsatellite markers concludes that males are not a limiting resource for this central Florida nesting aggregate.

Single paternity of clutches and sperm storage in the promiscuous green turtle (Chelonia mydas)

The rarity of multiple paternity in green turtles may reflect either a low proportion of multiple matings by females in this population, or sperm competition, possibly resulting from a first‐male sperm preference.

Original article Microsatellite analysis of polyandry and spawning site competition in brown trout (Salmo trutta L.)

Polyandry and competition for spawning sites in a sedentary brown trout population was studied using four highly variable microsatellite loci and a sequential procedure of multiple paternity analysis allowed the assignment of a single paternal genotype to each individual egg, to quantify the genetic contribution of different males.

In this study, the environment played a far stronger role in determining the success of clutches than whether paternity had been single or multiple, and contrary to the wide-spread assumption that multiple mating by female marine turtles confers fitness benefits, none were apparent.

Variation in reproductive output of marine turtles

Microsatellites provide insight into contrasting mating patterns in arribada vs. non‐arribada olive ridley sea turtle rookeries

The results suggest that the differences observed in levels of MP between arribada and solitary rookeries are due to an effect of abundance of individuals on the mating system, supported by a regression analysis combining other paternity studies on sea turtles which shows that levels ofMP increase with increasing abundance of nesting females.

Genetic parentage assessment in the crayfish Orconectes placidus, a high‐fecundity invertebrate with extended maternal brood care

Genetic parentage analyses of more than 900 progeny from 15 wild crayfish broods revealed that gravid females were invariably the exclusive dams of the offspring they tended, and that most of the females had mated with multiple males who contributed sometimes highly skewed numbers of offspring to a brood.

Nesting data for the loggerhead sea turtle (Caretta caretta) are presented over a 19-year period (1984-2002) from Laganas Bay, Zakynthos Island, Greece. The nesting habitat is comprised of six…
