Fig 6. Non-metric multidimensional scaling using Bray Curtis dissimilarity distances.
A distance matrix of bee community composition using the Bray Curtis index was used to form a non-metric multidimensional scaling plot. Fields that are closer in ordination space have more similar bee community composition. Ellipses represent groupings by region using 0.95 confidence interval. The arrows indicate the direction of increasing semi-natural habitat for 300 m, 1000 m and 2000 m radii in the ordination space for all fields. The length of arrows is proportional to the strength of the correlation of semi-natural habitat and the ordination.
