Parentage complexity in socially monogamous lemurs (Eulemur rubriventer): Integrating genetic and observational data.

摘要: Genetic analyses of parentage sometimes reveal that "socially monogamous" (pair-living) species do not reside in strict family groups. Circumstances such as adult turnovers and extra-pair copulations, among others, may result non-nuclear families. These genetic relationships within groups have implications for interpreting social behaviors. Red-bellied lemurs (Eulemur rubriventer) live generally comprising an male-female pair plus immatures, early a relatively small sample suggested they mate monogamously. However, previous research on this taxon has also identified scenarios which families might result, turnovers. To assess the potential occurrence taxon, well conditions under occur, we combined behavioral observations wild red-bellied Ranomafana National Park with analysis immatures from 17 We found majority (75%) represented nuclear 25% at some point during study. The factors resulted were varied included least one turnover, potentially delayed female dispersals copulations. Our results suggest are reproductively monogamous, only limited evidence non-monogamous reproduction. similar to other pair-living primates, appear exhibit flexibility their organization mating strategies. Multiple lines should be considered when inferring parent-offspring
