Ecologists tease out private lives of plants and their pollinators
Date:5/5/2008

using volatile compounds.

By helping understand the advantages and disadvantages of plant-pollinator relationships where particular plants rely on particular insects to reproduce, and those insects rely on the same plants for food, the results could help ecologists conserve certain bumblebee species and the species-rich chalk grassland and hay meadow communities in which they live, all of which are becoming increasingly rare.

For the plant, relying on a small group of insects such as bumblebees as pollinators is very beneficial because it ensures efficient pollen transfer. Bumblebees quickly learn to visit the most rewarding flowers, so providing protein-rich pollen is one way plants can encourage bumblebees to be faithful. But this close relationship has many potential pitfalls, because if the pollinators are lost, the flowers may not be able to reproduce, and this may be what we are seeing in the hay meadows, chalk grasslands and bumblebees species throughout Northern Europe, Hanley says.
