Extended Data Figure 1: Annual nectar productivity and diversity in linear features in 2007.
From: Historical nectar assessment reveals the fall and rise of floral resources in Britain
a, Box plots of log10 (x + 1) nectar productivity according to the location of the vegetation surveyed (area (nonlinear) versus linear features) in each habitat. b, Box plots of species nectar diversity according to the location of the vegetation surveyed (area versus linear features) in each habitat. c, Box plots of functional nectar diversity according to the location of the vegetation surveyed (area versus linear features) in each habitat. Significant differences of locations (area versus linear features) in habitats are indicated by asterisks as follows: *P ≤ 0.05; **P ≤ 0.01; ***P ≤ 0.001. Statistical models were re-run without calcareous grassland habitat (to meet residuals homoscedasticity constraint) in order to check that significant effects remained. See Extended Data Table 1 for ANOVA results. See ‘Statistical analyses’ section of the Methods for detailed statistical methods and definition of box plot elements.
