Pollen dispersal is driven by pollinator response to plant disease and plant spatial aggregation
Original language description
Most plant species are pollinated by animals, mainly insects, who adjust their foraging behaviour to the spatial distribution of rewards. Any changes in rewards of individual plants could then affect pollen dispersal at the level of plant patches or populations. Such change in floral rewards often results from infection by plant pathogens, for example by anther smuts (i.e. no pollen and reduced nectar in diseased flowers). Here, we tested the hypothesis that the infection of plant populations by anther smuts affects the pattern of pollen dispersal. We investigated the patterns of pollen dispersal in experimental arrays of potted plants differing in the presence of diseased plants and the degree of plant spatial aggregation. We tracked pollen dispersal using a fluorescent dye powder as a pollen analogue, while we simultaneously observed pollinator foraging behaviour. We found that the dispersal of the pollen analogue increased in the presence of diseased plants in experimental arrays, but this effect was strongly dependant on plant spatial aggregation. The parallel observations of pollinator behaviour suggest that this pattern resulted from pollinator discrimination against diseased plants and increased movement in arrays with intermingled diseased plants, provided that plant clusters were close to each other. Our study indicates that pollinators respond to diseased plants in a similar way as to healthy plants with low rewards. Consequently, diseased plants should be treated not only as a potential source of infection but also as a factor influencing pollen dispersal in plant populations.
