Table 3 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 3. Characteristics of each niche modelled, giving mean (± 1 s.d.) of each layer for each pygmy Myosotis taxon modelled, and the percentage that layer contributed to each model for both the seven-layer and nine-layer modelled niche.

The higher the percentage, the more closely a taxon’s distribution is correlated with the variation found in that layer. A Excluding two samples from Chile, and only modelling the New Zealand + subantarctic Islands (seven-layer model).
