Island phytophagy: explaining the remarkable diversity of plant-feeding insects.
Plant-feeding insects have undergone unparalleled diversification among different plant taxa, yet explanations for variation in their diversity lack a quantitative, predictive framework. Island biogeographic theory has been applied to spatially discrete habitats but not to habitats, such as host plants, separated by genetic distance. We show that relationships between the diversity of gall-indu...
متن کاملMacroevolutionary trade-offs in plant-feeding insects
Most plant-feeding insects are ecological specialists restricted to one or a few closely related host-plant species. A long-standing hypothesis asserts that natural selection favors host specialization because of trade-offs between performance on alternative hosts, yet empirical evidence for such tradeoffs is scarce. Here we assess trade-offs between adaptations to alternative hosts over macroe...
متن کاملDiversity and Abundance of Insects in Wukari, Taraba State, Nigeria
A field survey was conducted in Wukari, Taraba State to assess the diversity and abundance of insect species in selected habitats (residential, open field made up of grassland and an agroecosystem). Sampling were done biweekly using light, pitfall and yellow pan traps set in 3 replicates, 30 m apart. Insects recovered were wet preserved in 70% ethanol except butterflies and moths. Representativ...
متن کاملMicro- and Macroevolutionary Trade-Offs in Plant-Feeding Insects.
A long-standing hypothesis asserts that plant-feeding insects specialize on particular host plants because of negative interactions (trade-offs) between adaptations to alternative hosts, yet empirical evidence for such trade-offs is scarce. Most studies have looked for microevolutionary performance trade-offs within insect species, but host use could also be constrained by macroevolutionary tra...
