Table 4 in Taxonomic revision of the southern hemisphere pygmy forget-me-not group (Myosotis; Boraginaceae) based on morphological, population genetic and climate-edaphic niche modelling data

Table 4. Niche overlap as calculated using the D statistic (Warren et al. 2008) between pairs of modelled niches in the pygmy forget-me-not (Myosotis) group.

Niches compared in this table were modelled using the nine-layer dataset (LENZ + WorldClim) with default background sampling, and, in parentheses, the overlap between niches modelled using only the seven WorldClim layers and including the New Zealand subantarctic islands, are given. Although the original intention was to model these niches including southern Chile (to model the full extent of the range of M. antarctica), insufficient presence points in Chile meant that those models were poor predictors of distribution.
A The pair of niches were found to be indistinguishable using the niche identity test; all other pairs were tested and were found to not be identical.
