Evolution of seed dispersal in the Cerrado biome: ecological and phylogenetic considerations Acta Botanica
Kuhlmann,Marcelo; Ribeiro,José Felipe.
ABSTRACT The investigation of the phylogeny of a group of organisms has the potential to identify ecological and evolutionary processes that have been occurring within a community. Seed dispersal is a key process in the life cycle of vegetation and reflects different reproductive strategies of plants to a set of ecological and evolutionary factors. Knowing the dispersal syndromes and fruits types of a plant community may help elucidate plant-animal interactions and colonization strategies of plants. We investigated dispersal syndromes and fruit types in Cerrado formations as a parameter for understanding the evolution of angiosperm reproductive strategies in this mega-diverse tropical biome. To do this we identified and mapped the distribution of different...

Fruits and frugivores of the Brazilian Cerrado: ecological and phylogenetic considerations Acta Botanica
Kuhlmann,Marcelo; Ribeiro,José Felipe.
ABSTRACT Knowing the morphological and phylogenetic patterns of fruits of a plant community may elucidate plant-frugivore interactions, and analysis of dispersal syndromes is a practical approach to understanding these mutualisms. We investigated different zoochorous fruits and frugivorous animals among Cerrado formations (forest, savanna and grassland), mapped dispersal syndromes on a Cerrado angiosperm phylogeny and tested for phylogenetic signal. For a core region in Cerrado, we found that, among almost a thousand fruit species and 258 fruit-eating vertebrates, 60% of the fruits had an ornithochorous syndrome and that 70% of the frugivores were birds. Most fruit and frugivorous species (~80%) inhabit forest formations, but many of them also occurred in...
