Extended Data Table 1 Type III ANOVA (F-tests) results for annual nectar productivity, species nectar diversity and functional nectar diversity

From: Historical nectar assessment reveals the fall and rise of floral resources in Britain

  1. a, 2007 values according to habitat. The linear mixed effect models were performed on data from 2,576 nonlinear plots surveyed in 2007. b, 2007 values according to habitat and location. The linear mixed effect models were performed on data from 4,527 plots (2,576 nonlinear plots and 1,951 linear plots) surveyed in 2007. c, 1978–2007 values according to habitat and year. The linear mixed effect models were performed on data from 768 shared plots surveyed in 1978, 1990, 1998 and 2007. The annual nectar productivity was systematically log10 (x + 1) transformed.
