  1. Drawn from native North American (QAMF) and introduced Kashmir Himalayan (IAMF) regions with reference to uninvaded control samples (IAMFC) in the introduced region. aPercent coverage of the clone libraries is defined by the equation C = 1 − (n1/N), where n1 is the number of clones that occurred only once (frequency = 1), and N is the total number of clones examined (Good, I.L. 1953. The population frequencies of species and the estimation of population parameters. Biometrika 40, 237-264). bRarefaction predicts the diversity that would probably be observed in sample of reduced size (Foote, M. 1992. Rarefaction analysis of morphological and taxonomic diversity. Paleobiology 18, 1-16).
