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

Bees use honest floral signals as indicators of reward when visiting flowers
AC Knauer, FP Schiestl - Ecology letters, 2015 - Wiley Online Library
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 …

Honesty, reliability, and information content of floral signals
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 …

Pollinator shifts, contingent evolution, and evolutionary constraint drive floral disparity in Salvia (Lamiaceae): Evidence from morphometrics and phylogenetic …
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 …

Natural selection acting on integrated phenotypes: covariance among functional leaf traits increases plant fitness
Plant functional strategies are usually accomplished through the simultaneous expression of
different traits, and hence their correlations should be promoted by natural selection. The …

Honest floral signalling traits vary across and within populations in an insect‐pollinated plant
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 …

Reward regulation in plant–frugivore networks requires only weak cues
Abstract Theory assumes that fair trade among mutualists requires highly reliable
communication. In plant–animal mutualisms the reliability of cues that indicate reward …

Intraspecific relationships between floral signals and rewards with implications for plant fitness
CJ Essenberg - AoB Plants, 2021 - academic.oup.com
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 …
