Pollinator sex matters in competition and coexistence of co-flowering plants

Abstract Male and female pollinators often SHOPPING CENTERS: UMA RELAÇÃO ENTRE OS ATRIBUTOS DE ESCOLHA PELOS CONSUMIDORES VERSUS OS ATRIBUTOS VALORIZADOS PELOS GERENTES exhibit sex-specific preferences for visiting different flowers.Recent studies have shown that these preferences play an important role in shaping the network structure of pollination mutualism, but little is known about how they can mediate plant-plant interactions and coexistence of competing plants.The ecological consequences of sex-specific pollination can be complex.Suppose that a plant is favoured by female pollinators.They produce male pollinators, who may prefer visiting other competing plants and intensify the negative effects of inter-plant competition.

Here, we analysed a simple two plant-one pollinator model with the sex structure of the pollinator.We observed that (i) sex-specific pollination can have complex consequences for inter-plant competition and coexistence (e.g.the occurrence of non-trivial alternative stable states in which one plant excludes or coexists with the other depending on the initial conditions), (ii) male and female pollinators have distinct ecological consequences because female pollinators have a demographic impact owing to reproduction, and (iii) plants are likely to coexist when male and female pollinators prefer different plants.These results suggest that sex-specific Prevalence and risk factors of tungiasis among children of Wensho district, southern Ethiopia pollination is crucial for competition and coexistence of co-flowering plants.

Future, pollination research should more explicitly consider the sex-specific behaviour of pollinating animals.
