Table 1. Hypothesised predictions of variable effects on range sizes and their effects and significance (Sig.) or non-significance (NS) in the models for both native and introduced fern species, and for introduced species only
Figure 1. Range sizes of all fern species occurring on the main islands of New Zealand (n = 254), calculated using area of ecological districts occupied and range polygons shown as (a) frequency histograms and (b) ranks from smallest to largest range size
Figure 3. Model average predictions and their standard errors representing the effects of biostatus and (a) whether epiphytic (or not), (b) habitat specialist or generalist, and (c) number of altitudinal zones occupied (observed data are shown as points) on range size (area of ecological districts occupied) for 165 New Zealand fern species.
Table 2. Linear mixed effects model AICc model comparison statistics showing the relationships between (a) range sizes and random effects combined (Rmodel was 2.13, meaning that the “Full” model is 2.13 times more likely to be the best fit model in the mod
