Abstract and Summary

A study of food provisioning in a captive family group of South American maned wolves (Chrysocyon brachyurus) revealed a significant contribution by the adult male. The father was solicited by his two pups to regurgitate food nearly three times more frequently than was the mother and regurgitated to them twice as frequently as did the mother. These observations suggest that adult maned wolves may not be as asocial as previously thought, and that the adult male may contribute more to the fitness of his offspring than was previously known.

Zusammenfassung

In einer gefangen gehaltenen Familiengruppe des südamerikanischen Mähnenwolfes (Chrysocyon brachyurus) wurde der Vater von seinen zwei Jungen dreimal häufiger als die Mutter um Futter angebettelt, und er würgte doppelt so häufig Futter vor wie die Mutter. Männliche Mähnenwölfe scheinen stärkere Familienbindung zu haben und mehr zur Fitneß ihrer Jungen beizutragen, als bisher angenommen wurde.
