Document Summary
Bio120h lisa zhao 2011 | page 5. Ex. maple trees (native in na, non-native in europe) Seedlings from both grown on native soil were inhibited. On soil from non-native growth increased. Thus, soil org. associated w/ native species facilitate the establishment of non-native maples in native soils, facilitating interactions of this kind are overshadowed by the inhibitory influence of natural enemies in the soil. The differing adaptations of early and late successional species. Early and late species have. diff. growth and reproduction strategies. Climax species: disperse and grow slowly, shade-tolerant seedlings, large size when mature; thus, more competitive than early. Thus, there is a shift in the balance b/w adaptations promoting dispersal, rapid growth, early reproduction, and competitive ability enhancement. Early have small, wind-dispersed seeds which can remain dormant. Sseeeedd bbaannkk: dormant seeds in the soil that can germinate when conditions are favourable.
