RESUMO:

Context. The dispersal of aquatic macrophytes is primarily attributed to hydrochory and zoochory by aquatic birds. However, the potential role of mammals in the dispersal of these plants through aquatic environments has not been exhaustively investigated. Aims. The aim of this study was to investigate the role of capybaras Hydrochoerus hydrochaeris in the dispersal of the aquatic fern Salvinia auriculata in lagoons in southeastern Brazil. Methods. Over a three-year period, we monitored the presence of capybaras and S. auriculata in a set of 20 marginal lagoons of a river. Key results. The presence of H. hydrochaeris had a significant effect on the presence of S. auriculata, indicating that the presence of capybaras can increase the probability of colonization of a lagoon by S. auriculata by 71%. Implications. The findings of this study suggest that the observed increase in capybara populations has contributed to the upstream colonization of S. auriculata in lagoons where this potential weed was not previously present. Consequently, this has facilitated its dispersal throughout the study region.
