Fertility assurance through extrapair fertilizations and male paternity defense.
Extrapair paternity has been observed in many formally monogamous species. Male pursuit of extrapair fertilizations is explained by the advantages of having offspring that receive essential paternal care from other males. Since females are capable of exercising a degree of control over the post-copulatory sperm competition, extrapair paternity cannot persist unless it confers fitness benefits o...
متن کاملFemale blue tits adjust parental effort to manipulated male UV attractiveness.
The differential allocation hypothesis predicts that parents should adjust their current investment in relation to perceived mate attractiveness if this affects offspring fitness. It should be selectively advantageous to risk more of their future reproductive success by investing heavily in current offspring of high reproductive value but to decrease investment if offspring value is low. If the...
متن کاملA self-consistent approach to paternity and parental effort.
We review the relationship between optimal parental effort and paternity, and emphasize the need for a self-consistent approach. A fundamental consistency condition is what we refer to as the conservation of paternity. Every offspring has exactly one father. If a male has a paternity of less than unity, then another male or other males must have gained the lost paternity. Our approach also emph...

متن کاملConfidence of Paternity and Male Parental Care
-We present a theoretical framework in order to understand how the relationship between male parental care and paternity is dependent on the relationship between male parental care and offspring recruitment. When there is an S-shaped relationship between offspring recruitment and the parental care of a single male, we predict a threshold relationship between male parental care and paternity. Tr...
