Few Ant Species Play a Central Role Linking Different Plant Resources in a Network in Rupestrian Grasslands. [PDF]
PLoS ONE, 2016 Ant-plant associations are an outstanding model to study the entangled ecological interactions that structure communities. However, most studies of plant-animal networks focus on only one type of resource that mediates these interactions (e.g, nectar or ...

Are native bees and Apis mellifera equally efficient pollinators of the rupestrian grassland daisy Aspilia jolyana (Asteraceae)? [PDF]
Acta Botânica Brasílica, 2018 Most angiosperms rely on animals for pollination, and insects, especially bees, are being the most frequent pollinators. Many native Neotropical plants are frequently visited by the invasive honeybee (Apis mellifera), but its role in the pollination of ...
