Palms are considered key species from an ecological and economic perspective, with multiple uses for local communities. Many species of mammals, such as agoutis, primates, and peccaries, are considered important dispersers of large seeds. However, very little is known about the specific palm-animal association. This study focuses on the association piedmont important palms, Socratea spp. and Iriartea deltoidea with mammals, through indirect observations with camera traps placed in front of these species of palms during the fruiting period. Twenty-one camera trap stations were used between September 26, 2016 and December 7, 2017, located in three transects of three kilometers each, in the Colonso-Chalupas Biological Reserve, with a sampling effort of 2307 traps/night (1569 for I. deltoidea and 738 for Socratea spp.). We recorded 46 visits of 11 species of mammals associated with Socratea spp. and 128 visits of 12 species with I. deltoidea. The two palms shared 10 species, being the most abundant for both Cuniculus paca, Dasypus novemcinctus, and Hadrosciurus igniventris, with more than five occurrences, followed by Myoprocta pratti, Dasyprocta fuliginosa, and Eira barbara; although these last three species were more frequent in I. deltoidea. We observe more visits in I. deltoidea than in Socratea spp., however, this could be related to the availability of fruits, since I. deltoidea offers more fruits during the year and by palm. The association found with Socratea spp. is a new contribution and the results of the study offer relevant information for the development of management and conservation plans for protected areas.
