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
TLDR
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)
TLDR
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.
Prevalence of polygyny in a critically endangered marine turtle population
TLDR
The high level of polygyny documented suggests there may be a limited number of sexually mature males at Bahia de Jiquilisco and highlights key management uncertainties, including whether polygynous mating strategies can compensate for potential ongoing feminization and the low number of adult males found.
High frequency of multiple paternity in a solitary population of olive ridley sea turtles in Honduras
TLDR
This work finds evidence of multiple paternity in an olive ridley solitary population nesting in the Gulf of Fonseca, Honduras, and shows that multiple paternity studies can be effectively performed in the absence of maternal samples, and that pooled DNA samples can be used with results comparable to individual hatchling sampling in multiple paternity analyses.
First observation of multiple paternity in loggerhead sea turtles, Caretta caretta, nesting on Dalyan Beach, Turkey
TLDR
It was detected that both the number and genotype of contributing sires was same in all clutches of a given female, possibly due to the lack of successful inter-nesting mating in this population, which implies the possible high genetic diversity within this population.
Multiple paternity at the largest green turtle (Chelonia mydas) rookery in the Mediterranean
TLDR
The pattern of multiple paternity and reconstructed paternal genotypes in the largest green turtle nesting site of the Mediterranean, Akyatan beach, Turkey, is investigated using nine dinucleotide microsatellite loci to provide an indirect estimate of breeding male population size.
Multiple paternity in the East Pacific green turtle (Chelonia mydas) from the Pacific coast of Mexico
TLDR
Investigating multiple paternity in C. mydas using microsatellites to determine the number of males that fertilized clutches during two nesting seasons at a high-density nesting beach in the west coast in Michoacan state, Mexico indicated that multiple paternity occurred in up to 75% of the nest samples.
Seasonal monogamy and multiple paternity in a wild population of a territorial reptile (tuatara)
TLDR
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)
TLDR
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.
A Review of Patterns of Multiple Paternity Across Sea Turtle Rookeries.
TLDR
It is shown that the specifics of movement patterns play a key role in driving packing density and hence the likely rate of male-female encounters and the findings suggest that multiple paternity in sea turtles may have no benefit, but is simply a consequence of the incidence ofmale- female encounters.

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

TLDR
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
TLDR
Green turtles nesting in Years when large numbers of nests were recorded laid a greater number of clutches than females nesting in years with lower levels of nesting, suggesting green turtles may not be able to achieve their maximum reproductive output with respect to clutch size throughout the season.
Microsatellites provide insight into contrasting mating patterns in arribada vs. non‐arribada olive ridley sea turtle rookeries
TLDR
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
TLDR
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.
