Evolutionary shifts to bird pollination (ornithophily) have occurred independently in many
lineages of flowering plants. This shift affects many floral features, particularly those …

At least half of the 3600 species of Bromeliaceae are pollinated by hummingbirds. There is
little doubt that the four to 12 evolutionary shifts towards and c. 32 shifts away from …

• Premise: Bromeliaceae form a large, ecologically diverse family of angiosperms native to
the New World. We use a bromeliad phylogeny based on eight plastid regions to analyze …

The year 2000 marks 500 years of massive destruction for the Brazilian Atlantic Forest, as a
consequence of the European colonization of Brazil. Today, the Atlantic Forest is restricted …

Background and aims Pollination is a critical stage in plant reproduction and thus in the
maintenance and evolution of species and communities. The Caatinga is the fourth largest …

Aim We review several aspects of the structure of regional and local assemblages of nectar‐
feeding birds and bats and their relationships with food plants to determine the extent to …

Large-scale geographical patterns of biotic specialization and the underlying drivers are
poorly understood, but it is widely believed that climate plays an important role in …

A comparison between bat-pollinated plant assemblages at two sites in different altitudinal
ranges covered by the Atlantic rainforest in southeastern Brazil is presented. The lowlands …

Functional traits can determine pairwise species interactions, such as those between plants
and pollinators. However, the effects of biogeography and evolutionary history on trait …

Although specialized interactions, including those involving plants and their pollinators, are
often invoked to explain high species diversity, they are rarely explored at …
