Pollination Ecology of Wind and Insect Systems

Pollination ecology examines how pollen is transferred between plants and how floral traits, environmental conditions and pollinator communities shape reproductive success. Insect‐mediated pollination (entomophily) relies on floral rewards, sensory cues and specialised morphology to attract beetles, bees, flies and other invertebrates, driving high levels of outcrossing, genetic diversity and coevolution. Wind pollination (anemophily) is characteristic of many grasses, trees and sedges, featuring reduced perianths, copious lightweight pollen and inflorescences optimised for air currents. Mixed strategies (ambophily) occur where both wind and insect vectors contribute to fruit set, often in variable or marginal habitats. Recent advances highlight the macroevolutionary origins of these systems, the functional trade-offs underpinning floral syndromes, and the role of environmental gradients—from forest interiors to open grasslands—in shaping the balance between abiotic and biotic pollen transfer. Understanding these dynamics has practical implications for crop breeding, habitat restoration and the conservation of pollinator networks under global change.

Research from Nature Portfolio

Experimental work on a tropical seagrass has revealed a novel mixed pollination system in which benthic invertebrates carry pollen in mucilage from male to female flowers during nocturnal openings. In the absence of water flow, visitation by crustaceans and molluscs transfers viable pollen and elicits pollen-tube formation, demonstrating a zoobenthophilous syndrome that bridges hydrophily and animal pollination. This finding challenges the notion of purely abiotic pollination in marine angiosperms and expands our understanding of pollination diversity in aquatic ecosystems.
