Resumen:
Understanding the evolution of mating systems, a central topic in evolutionary
biology for more than 50 years, requires examining the genetic consequences
of mating and the relationships between social systems and mating systems.
Among pair-living mammals, where genetic monogamy is extremely rare,
the extent of extra-group paternity rates has been associated withmale participation
in infant care, strength of the pair bond and length of the breeding
season. This study evaluated the relationship between two of those factors
and the genetic mating system of socially monogamous mammals, testing
predictions that male care and strength of pair bond would be negatively correlated
with rates of extra-pair paternity (EPP). Autosomal microsatellite
analyses provide evidence for genetic monogamy in a pair-living primate
with bi-parental care, the Azara?s owl monkey (Aotus azarae). A phylogenetically
corrected generalized least square analysis was used to relate male care
and strength of the pair bond to their genetic mating system (i.e. proportions
of EPP) in 15 socially monogamous mammalian species. The intensity of male
care was correlated with EPP rates in mammals, while strength of pair bond
failed to reach statistical significance. Our analyses showthat, once social monogamy
has evolved, paternal care, and potentially also close bonds, may
facilitate the evolution of genetic monogamy.
