摘要: Wing-dimorphic, delphacid planthoppers were used to test hypotheses concerning the effects of habitat persistence and architectural complexity on occurrence dispersal. For reasons both durational stability reduced availability mates, selection has favored high levels dispersal in species occupying temporary habitats. Flightlessness predominates persistent habitats, is promoted by a phenotypic trade-off between reproductive success flight capability. Wings are retained tree-inhabiting species, probably for more effective negotiation three-dimensional In contrast, flightlessness characteristic those inhabiting low profile host plants. several genera, migratory larger than their sedentary congeners. Because body size fecundity positively related planthoppers, large observed taxa may result from increased colonizing species.
