Fig. 2From: Unraveling the importance of functionally extreme tadpole types to functional diversity: a case study in temperate montane streamsThe distribution of tadpole functional entities in the functional space. A Functional space constructed by the first two PC axes. B Functional space constructed by PC3 and PC4. The outer convex polygon represents the area occupied by all functional entities in the functional space, while the inner convex polygon represents the area occupied by the GFE in the functional space. The red dots represent EFE, and the black dots represent GFE. Details of the abbreviations are in Table 1Back to article page
