Changes in the relative abundance and movement of insect pollinators during the flowering cycle of Brassica rapa crops: implications for gene flow.

The article discusses the results of a study that examined the effect to the gene flow of changes in the abundance and movement of insect pollinators during Brassica rapa crops' flowering cycle. It notes the varying abundance of flower-visiting insects with the phenology of the Brassica crop. Variation is also noted in the ratio of flower-visiting insects entering and leaving crop fields.
