Background Floral nectar is an important determinant of plant–pollinator interactions and an
integral component of pollination syndromes, suggesting it is under pollinator-mediated …

Pollinators visit flowers for rewards and should therefore have a preference for floral signals
that indicate reward status, so called 'honest signals'. We investigated honest signalling in …

Plants advertise their presence by displaying attractive flowers, which pollinators use to
locate a floral reward. Understanding how floral traits scale with reward status lies at the …

Antecedentes: Lamiaceae es una de las familias con mayor riqueza de especies en México.
Sin embargo, aún se carece de un estudio detallado sobre su diversidad en el país y de una …

Switches in pollinators have been argued to be key drivers of floral evolution in
angiosperms. However, few studies have tested the relationship between floral shape …

Plant functional strategies are usually accomplished through the simultaneous expression of
different traits, and hence their correlations should be promoted by natural selection. The …

In flowering plants that produce concealed rewards, pollinator foraging preferences may
select for floral advertisement traits that are correlated with rewards. To date, studies have …

Aims Adaptive convergence in floral phenotype among plants sharing a pollinator guild has
been acknowledged in the concept of pollination syndrome. However, many plants display …

Abstract Theory assumes that fair trade among mutualists requires highly reliable
communication. In plant–animal mutualisms the reliability of cues that indicate reward …

Within-species variation in traits such as petal size or colour often provides reliable
information to pollinators about the rewards offered to them by flowers. In spite of potential …
