Frugivory and seed dispersal in the Cerrado: Network structure and defaunation effects

Seed dispersal is a fundamental process that is highly threatened by the rapid decline of large-bodied frugivores worldwide. The Brazilian Cerrado, the largest savanna in the world, represents an ideal site for investigating seed dispersal because of its biodiversity, environmental challenges, and knowledge shortfalls. We performed a Systematic Literature Review to analyze the seed dispersal network in the Cerrado and the potential impacts of the defaunation of large-bodied frugivores on it. We considered network metrics, calculated the defaunation index of the frugivore assemblage, and compared traits among different fruit-sized plants and their respective dispersers in the network. We retrieved 1,565 interactions involving 193 plant species and 270 animal species. Results show that the Cerrado seed dispersal network is slightly nested and considerably modular, dominated by small to medium-sized generalist species, such as passerines, marsupials, and mesocarnivores. Nonetheless, large-..., The dataset on seed dispersal interactions was obtained from studies retrieved in a systematic literature review. Data on species traits (e.g., dispersers' body mass, fruit and seed size) were obtained from specific literature. , To open the spreadsheet files included in our submission, you can use 'Microsoft Excel' or any alike software.Â
