    الوصف: The data set provided here includes 8,320 frugivory interactions (records of pairwise interactions between plant and frugivore species) reported for the Atlantic Forest. The data set includes interactions between 331 vertebrate species (232 birds, 90 mammals, 5 fishes, 1 amphibian, and 3 reptiles) and 788 plant species. We also present information on traits directly related to the frugivory process (endozoochory), such as the size of fruits and seeds and the body mass and gape size of frugivores. Data were extracted from 166 published and unpublished sources spanning from 1961 to 2016. While this is probably the most comprehensive data set available for a tropical ecosystem, it is arguably taxonomically and geographically biased. The plant families better represented are Melastomataceae, Myrtaceae, Moraceae, Urticaceae, and Solanaceae. Myrsine coriacea, Alchornea glandulosa, Cecropia pachystachya, and Trema micrantha are the plant species with the most animal dispersers (83, 76, 76, and 74 species, respectively). Among the animal taxa, the highest number of interactions is reported for birds (3,883) followed by mammals (1,315). The woolly spider monkey or muriqui, Brachyteles arachnoides, and Rufous-bellied Thrush, Turdus rufiventris, are the frugivores with the most diverse fruit diets (137 and 121 plants species, respectively). The most important general patterns that we note are that larger seeded plant species (>12 mm) are mainly eaten by terrestrial mammals (rodents, ungulates, primates, and carnivores) and that birds are the main consumers of fruits with a high concentration of lipids. Our data set is geographically biased, with most interactions recorded for the southeast Atlantic Forest.

    الوصف: As alterações antropogênicas ao ambiente vêm afetando muitos componentes dos ecossistemas naturais, produzindo frequentemente um padrão não aleatório de extinções, associado a características espécie-específicas. Por sua vez, a extinção local de espécies muitas vezes se traduz na perda de interações. Dessa forma, a perda de frugívoros, pode acarretar mudanças na estrutura das interações mutualísticas, com consequências futuras para espécies de plantas que dependem destes para a dispersão de suas sementes. Uma das espécies potencialmente afetada pela perda de frugívoros, principalmente os de grande porte, é o palmito juçara (Euterpe edulis). Exploramos aqui então se a extinção local de aves frugívoras se dá de uma maneira não aleatória e investigamos as consequências dessas extinções para o processo de remoção e dispersão de sementes de E. edulis. Observamos um padrão aninhado e modular na comunidade de dispersores de sementes de palmito juçara, indicando que as extinções ocorrem de forma não aleatória. Utilizando um índice de diversidade taxonômica observamos também que certos clados taxonômicos são mais propensos à extinção local, assim como previmos no início. Assim, fica então evidente que a extinção local dos frugívoros de E. edulis ocorre de maneira não aleatória, havendo estreita relação taxonômica entre estas espécies primariamente extintas, sendo os grande dispersores os mais afetados. Em áreas não defaunadas, apesar de observarmos uma baixa taxa de visitação, há uma alta taxa de consumo, sendo os grandes e médios dispersores importantes responsáveis pela remoção de sementes nestes locais. Em contrapartida, consequência da própria perda dos grandes frugívoros, áreas defaunadas demostraram baixa visitação de frugívoros aos frutos de E. edulis e baixa taxa de consumo destes, sendo os principais dispersores.

    الوصف: Local extinctions have cascading effects on ecosystem functions, yet little is known about the potential for the rapid evolutionary change of species in human-modified scenarios. We show that the functional extinction of large-gape seed dispersers in the Brazilian Atlantic forest is associated with the consistent reduction of seed size of a keystone palm species. Among 22 palm populations, areas deprived of large avian frugivores for several decades present smaller seeds than non-defaunated forests, with negative consequences for palm regeneration. Coalescence and phenotypic selection models indicate that seed size reduction most likely occurred within the last 100 years, associated with human-driven fragmentation. The fast-paced defaunation of large vertebrates is most likely causing unprecedented changes in the evolutionary trajectories and community composition of tropical forests. ; Study localities list.
