Multiple paternity in the pueriparous North African fire salamander, Salamandra algira, supports polyandry as a successful mating strategy in low fecundity Salamandra lineages

Abstract: Multiple paternity is widespread in nature and despite costs, it has many associated benefits like increased genetic diversity and fertilization success. It has been described in many viviparous systems, suggesting the existence of some fitness advantages counteracting the inherent costs of viviparity, such as fecundity reduction and high parental investment. Reproductively polymorphic species, like the urodele Salamandra algira, which shows two types of viviparity: larviparity (i.e., delivering aquatic larvae… Show more
