Frugivory and potential seed dispersal by the exotic-invasive marmoset Callithrix jacchus (Primates, Callitrichidae) in an urban Atlantic Forest, Rio de Janeiro, Brazil

Exotic common marmosets (Callithrix jacchus) introduced to Rio de Janeiro's Tijuca National Park (TNP) demonstrate potential as seed dispersers for native plant species, despite being an invasive primate. Analysis of 60 feeding records over 361 hours revealed that fruits constituted nearly half (48.3%) of their diet, with seeds from four species swallowed intact and seven others found in feces, indicating successful dispersal. This finding is significant as it highlights the ecological role of an invasive species in an urban Atlantic Forest where native callitrichids are absent, providing critical insights for managing marmoset populations and conserving biodiversity in TNP.
