An interesting paper has moved into free access in Annals of Botany: Caught in the act: pollination of sexually deceptive trap-flowers by fungus gnats in Pterostylis (Orchidaceae). It sounds like a very specific paper,...
Bumble-bee workers assort themselves among Pedicularis species according to size, adjusting their buzzing behavior in relation to the species’ floral traits
A phylogenetic reconstruction suggests that parallel character evolution is the rule rather than the exception in Old World Salvia in Africa.
A single species of male gnat (Mycetophilidae) visits and pollinates the rewardless flowers of P. sanguinea. The gnats often show probing copulatory behaviour on the labellum, leading to its triggering and the temporary entrapment of the gnat in the flower.
Effects of pollination limitation and seed predation on female reproductive success of a deceptive orchid
For many species of conservation significance, multiple factors limit reproduction. In a new study published in AoB PLANTS, Walsh et al. examined the contribution of plant height, number of flowers, number of stems, as...
Kron et al. use flow cytometry to characterize pollen loads from individual bees, using DNA content as a species marker,
Parnassia epunctulata, a herb with generalized pollination, which exhibits sequential stamen movement.
A survey of flowers of 16 species of Lockhartia determines that all have elaiophores (oil glands) of the trichomal type.
Pat Willmer. 2011. Princeton University Press. £65. pp. 832. Any text book that tries to assess and summarise the whole of a multidisciplinary research field such as pollination ecology and floral biology is required...
