Flowering plants have had an intimate relationship with insects for millions of years. Indeed, this is often cited as an example of co-evolution , particularly with regards to the flowers and their pollination by the insects. However, this has also given parasites millions of years to adapt too.
Say the name Charles Darwin and pollination is not the first thing that springs to most people’s minds.
Different reproductive strategies are important for avoiding pollinator competition between sympatric populations of two Silene spp.
Hanging On To Your Date, Avoiding Incest And Not Getting Infected – All In A Day’s Work For Flowers Of The Mustard Family
In the mustard family, which includes the important crop Brassica (rapeseed/canola) and the model plant Arabidopsis, the surfaces of the female stigmatic cells are dry. These cells – on which the pollen grains land…
The Chiloglottis trapeziformis orchid attracts male wasp pollinators using chiloglottones, a newly discovered class of volatile substances.
Thanks to JSTOR Global Plants for pointing to an interesting paper in Functional Ecology, Shape matters: corolla curvature improves nectar discovery in the hawkmoth Manduca sexta. The research looks at how the the 3D…
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, and…
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.
