Description
Summary:Figure 4 Comparison of site latitude with site scores on the latitude-constrained CCA axis. Correlation between the two would indicate that species composition at sites is strongly associated with latitude. The southern sites show no strong latitudinal pattern (sites 1-22: R² = 0.0165) whereas northern sites do (sites 23-42: R² = 0.756).
