Putting pollination quality into analyses of floral ecology: testing syndromes through pollinator performance

, 2012
Over recent years, the extent of specialised and generalised plant-pollinator relationships, and the predictive powers of floral traits (often grouped into “pollination syndromes”) as indicators of the most effective pollinators of plant species, have ...
