The success of birds introduced to Tahiti or the Hawaiian Islands was dependent on the morphology of the species already present. If there was a small morphological difference in bill length between the resident and introduced species, then

#Unit 10. Ecological Principles
  1. the probability of successful establishment was high.
  2. the morphological differences between species are large, the probability of successful establishment was low.
  3. the probability of successful establishment was low.
  4. on these morphological differences do not  allow the species co-exist.
