Hybrid vigor for clonal growth in Carpobrotus (Aizoaceae) in coastal California

摘要: One of the consequences human-caused movement plant species around globe is hybridization between previously allopatric species. Introgressive non-native, invasive perennial succulent Carpobrotus edulis and putative native, non-invasive C. chilensis occurring throughout coastal California, leading to a high abundance aggressive hybrid morphotypes loss open space for native establishment growth. We test hypothesis that vigor vegetative growth resistance herbivory contributes successful invasion by morphotypes. compared survival transplanted cuttings three (parental hybrids) in habitats factorial watering caging experiment. Overall was both water herbivore limited. Hybrids displayed higher than either parental always had response chilensis, but survi...
