ENN: New Reason For Bee Hive Collapse: Ecologists Tease Out P...

The quality of pollen a plant produces is closely tied to its sexual habits, ecologists have discovered. As well as helping explain the evolution of such intimate relationships between plants and pollinators, the study -- one of the first of its kind and published online in the British Ecological Society's journal Functional Ecology -- also helps explain the recent dramatic decline in certain bumblebee species found in the shrinking areas of species-rich chalk grasslands and hay meadows across Northern Europe.
