Are Kirindy sifaka capital or income breeders? It depends

Article Abstract:

A study was conducted to evaluate data on Verreaux's sifaka (Propithecus verreauxi verreauxi) in the Kirindy Forest of western Madagascar to determine whether they are capital or income breeders. It was found that Verreaux's sifaka can be classified as either capital or income breeders, depending on how these concepts are operationalized, and these conflicting findings highlight why the capital/income framework is currently problematic and must be standardized if it is to be a useful framework for primatologists.

Seasonality, body condition, and timing of reproduction in Propithecus verreauxi verreauxi in the Kirindy Forest

Article Abstract:

A study was conducted to examine the effects of fluctuating food availability on body condition and reproduction in one of the larger living species, Verreaux's sifaka (Propithecus verreauxi verreauxi) in the Kirindy Forest of western Madagascar. It was observed that females were found to have greater body mass than males, while both male and female sifaka exhibited significant losses of body mass and fat during the dry season and that the sifaka follow the classic reproductive strategy.
