Changing Bee and Hoverfly Pollinator Assemblages along an Urban-Rural Gradient

Figure 3

Co-plot showing relationships between explanatory variables used in the generalized linear models.

Pairwise scatterplots are shown with locally weighted loess smoothing to aid visual interpretation and panels with a Pearson correlation >0.3 highlighted. Variable codes are abbreviated for clarity (exp. = % exposure, alt. = altitude in metres, flowR = flowering forb species richness, flowA = flowering forb flower abundance, tree = number of flowering trees, % gard. = % gardens within 500m, and% built = % built space within 500m). Percentage gardens and built space at 500m scale was used as an example because this was most representative of these variables at all wider landscape scales.
