Quantitative food webs are valuable tools to detect patterns in community structure and
generate hypotheses for experimentation. Quantitative webs of whole communities are …

Biological constraints and neutral processes have been proposed to explain the properties
of plant–pollinator networks. Using interactions between nectarivorous birds (hummingbirds …

Many tropical plants are pollinated by birds and several bird phylogenetical lineages have
specialised to a nectar diet. The long‐assumed, intimate ecological and evolutionary …

Despite a growing number of studies, the role of pollinators as a selection agent for nectar
traits remains unclear. Moreover, the lack of data from some biogeographic regions prohibits …

Many recent studies have suggested that the majority of animal-pollinated plants have a
higher diversity of pollinators than that expected according to their pollination syndrome …

The drivers behind plant‐pollinator interactions still need to be fully understood. Previous
research has suggested that observed interactions result from either neutral interaction …

The bird pollination systems of the New and Old Worlds evolved independently, and differ in
many aspects. New World plants are often presented as those adapted to hovering birds …

Differences in interaction specializations between nectarivorous birds and plants across
continents serve as common examples of evolutionary trajectory specificity. While New …

Plant–bird pollination interactions evolved independently on different continents. Specific
adaptations can lead to their restriction when potential partners from distant evolutionary …

Trait matching—a correlation between the morphology of plants and their pollinators—has
been frequently observed in pollination interactions. Different intensities of natural selection …
