Metrics used to infer inter-island colonization success of animal and plant species within the Galápagos, Azores and Canary Islands.

1 Number of current islands colonized by each species based on chorological data; (number of archipelago largest islands)
2 Number of haplotypes obtained from mitochondria (animals) and plastid (plants) DNA sequences in each study
3 Number of haplotypes obtained in each study multiplied by the number of all largest islands-1
4 Inter-island colonization events based on distribution of each haplotype, i.e. each colonization event is inferred by haplotype sharing on two or more islands
5 Ratio expressing multiple colonization events, that ranges between 1 (all islands colonized by all the haplotypes) and 0 (no inter-island colonization).
* Olea europaea subsp. guanchica is distributed across the seven Canary Islands. However, the three eastern-most islands show evidence for hybridization with the olive tree. This made the authors use only material from the four western-most islands.
