Abstract Multiple mating and sperm storage can influence reproductive strategies of males and females. Male reproductive success is often limited by the ability to acquire mates; therefore, males have evolved strategies to mate with multiple females. In contrast, the number of offspring a female produces is generally not limited by the quantity of sexual partners; thus, selection for multiple matings is expected to be weaker than in males. Evidence of polyandry and sperm storage is widespread…

Genetic Analysis of Multiple Paternity in an Endangered Ovoviviparous Lizard Shinisaurus crocodilurus

The results indicate that the primary mating mode of the crocodile lizard is that males are polygynous while with females are polyandrous, and there is multiple paternity among offspring of the same mother.



Multiple paternity, sperm storage, and reproductive success of female and male painted turtles (Chrysemys picta) in nature

It is documented that more than 30% of the clutches were likely fathered by multiple males, and that presence of multiple paternity was positively correlated with clutch size, and the data indicate that the second male to mate typically had high paternity precedence over the first.

Multiple copulations in natural populations of lizards: evidence for the fertility assurance hypothesis

It is shown that females with a high number of copulations had lower clutch size, but heavier offspring (controlled for a potential relationship between the two), than females with fewer copulations, which could be driven by sexual selection, ecological, and environmental factors.

Multiple paternity in reptiles: patterns and processes

It is argued that the most parsimonious explanation for patterns of multiple paternity is that it represents the combined effect of mate‐encounter frequency and conflict over mating rates between males and females driven by large male benefits and relatively small female costs, with only weak selection via indirect benefits.


The results imply that polyandry may be hierarchically controlled, with females controlling when to mate with multiple partners and male sexual harassment being a proximate determinant of the degree of multiple paternity.

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.

Multiple paternity and sperm storage lead to increased genetic diversity in Anolis lizards

Anolis sagrei is one of the most promiscuous amniote vertebrates studied and the genetic diversity among progeny from females that mate with multiple males is higher, and closer to the total genetic diversity in the population, compared with progenyFrom monogamous females.

Molecular determination of paternity in a natural population of the multiply mating polygynous lizard Eulamprus heatwolei

Neither male home range ownership nor body size is significantly correlated with the number of paternities a male obtained, which suggests a polygynous mating system for this species.

Complex mating system and dispersal patterns in a social lizard, Egernia whitii

The mating system, spatial organization, and dispersal patterns of E. whitii are examined using behavioural field studies and data from four microsatellite loci, and the implication of the results in regard to the factors promoting the evolution of monogamy within the Egernia group is discussed.

High levels of genetic monogamy in the group‐living Australian lizard Egernia stokesii

The results suggest that monogamy both within and between seasons is a common mating strategy of E. stokesii and that breeding partners maintain stable associations together and with multiple cohorts of their offspring over periods of up to at least 5 years.

The extent of inbreeding and inbreeding avoidance behaviours in rare lizards from southern New Zealand, including grand skinks, are investigated to test the hypothesis that adults are likely to encounter kin as potential mates and will inbreed.
