Pollinator aggregative and functional responses to flower density: Does pollinator response to patches of plants accelerate at low-densities?

Article Abstract:

A field experiment is conducted to determine the shape of the pollinator visitation response to patches of differing density of the common weed Brassica rapa. The results for entire pollinator community were consistent among temporal and spatial replicates, but there was no evidence that pollinators disproportionately visit denser patches, or that the conditions for this mechanism of pollination facilitation are likely to be met in the generalist pollinator system.

Faculative dichogamy and reproductive assurance in partially protandrous plants

Article Abstract:

The effects of dichogamy on plant pollination and reproduction are examined, specifically the form of protandry, in which the emergence of the stigma follows pollen presentation.
