Beyond the honeybee: How many bee species does a meadow need?

A meadow's lush array of flowers needs a full phalanx of bees to pollinate them—far more than just the honeybees and bumblebees that most people are familiar with, according to a new study by a team of researchers including ...

Field study shows pollinators prefer saltier nectar

A team of researchers affiliated with multiple institutions in the U.S., has found adding sodium to floral nectar increased both visits by pollinators and their diversity. In their paper published in the journal Biology Letters, ...

Pollination

Pollination is the process by which pollen is transferred in plants, thereby enabling fertilisation and sexual reproduction. Pollen grains transport the male gametes (sperm) to where the female gamete(s) are contained within the carpel; in gymnosperms the pollen is directly applied to the ovule itself. The receptive part of the carpel is called a stigma in the flowers of angiosperms. The receptive part of the gymnosperm ovule is called the micropyle. Pollination is a necessary step in the reproduction of flowering plants, resulting in the production of offspring that are genetically diverse.

The study of pollination brings together many disciplines, such as botany, horticulture, entomology, and ecology. The pollination process as an interaction between flower and vector was first addressed in the 18th century by Christian Konrad Sprengel. It is important in horticulture and agriculture, because fruiting is dependent on fertilisation, which is the end result of pollination.
