Fig. 2 — Non-metric Multidimensional Scaling (NMDS) ordination depicting variation in taxonomic composition of vascular and nonvascular plants in the 96 vegetation plots from the Endalen ITEX site (three habitats; Dryas heath, Cassiope heath, snowbed) and two elevation gradients (seabird colony nutrient input, reference). (a) Plot scores on NMDS axes 1 and 2, based on 74 taxa (see⁶⁷ for details). Shapes and colors indicate habitats and experimental treatment within the two study systems (Dryas heath (red), Cassiope heath (pink), snowbed (blue)) from the ITEX warming experiment (filled: control, open: warmed), and the seabird nutrient input (green) and reference (gray) gradients. Opacity indicates elevation of the sites, with darker color corresponding to higher elevation. (b) Species scores of selected taxa on NMDS axes 1 and 2 (see⁶⁷ for code to generate the NMDS scores for the full list of taxa).
