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

▪ Abstract Floral symmetry has figured prominently in the study of both pollination biology
and animal behavior. However, a confusion of terminology and the diffuse nature of the …

Extinction risk in vertebrates has been linked to large body size, but this putative relationship
has only been explored for select taxa, with variable results. Using a newly assembled and …

Shrubs and trees are assumed less likely to lose genetic variation in response to habitat
fragmentation because they have certain life‐history characteristics such as long lifespans …

Assemblages of neotropical hummingbirds are organized according to parameters of
available resources and morphological-behavioral attributes of particular hummingbird …

Flowerings and flower visitors were observed continuously in a lowland dipterocarp forest in
Sarawak, Malaysia, for 53 mo in 1992–1996. Flower visitors of 270 plant species were …

Ecological communities are organized in complex ecological networks. Trait‐based
analyses of the structure of these networks in highly diversified species assemblages are …

We studied 86 species of hummingbird‐pollinated flowers and their pollinators at a coastal
lowland site and two highland rain forest sites in southeastern Brazil. The Jaccard index for …

Empirical estimates of the relative importance of different barriers to gene flow between
recently diverged species are important for understanding processes of speciation. I …

Pollinator behaviour has profound effects on plant mating. Pollinators are predicted to
minimise energetic costs during foraging bouts by moving between nearby flowers …
