Existem visitantes florais que coletam recursos em flores sem realizar polinização, e
também há espécies de plantas que atraem polinizadores sem oferecer qualquer recurso. A …

Covering: up to the end of 2014 The field of chemical ecology was established, in large part,
through collaborative studies between biologists and chemists with common interests in the …

A predictive understanding of adaptation to changing environments hinges on a mechanistic
understanding of the extent and causes of variation in natural selection. Estimating variation …

Premise The role of pollinators in evolutionary floral divergence has spurred substantial
effort into measuring pollinator‐mediated phenotypic selection and its variation in space and …

Climate has the potential to influence evolution, but how it influences the strength or
direction of natural selection is largely unknown. We quantified the strength of selection on …

Spatiotemporal variation in natural selection is expected, but difficult to estimate. Pollinator-
mediated selection on floral traits provides a good system for understanding and linking …

Due to drastic changes in pollinators between native and invaded habitats, we might expect
that pollinator-mediated selection on floral traits of alien plants differ from that in their native …

Spatiotemporal variations in plant–pollinator interactions drive floral evolution and shape the
diversity of flowers in angiosperms. However, the potential role of plant–pollinator …

Nectarless flowers that deceive pollinators offer an opportunity to study asymmetric plant-
insect interactions. Orchids are a widely used model for studying these interactions because …

After a confused taxonomic history, Prosthechea (Laeliinae, Orchidaceae) has been
circumscribed in a broad sense to include species previously placed in Encyclia subg …
