The 1D NMDS does a strong relationship between type of wetland and ecological distance between plots.
Additionally, I created a two dimensional NMDS which had a stress of 0.29. Figure 25 shows the NMDS with vectors for environmental variables and ellipses for side. The upstream and downstream ellipses are overlapping and do not appear have distinct community compositions. The 2D NMDS is displayed again in figure 26, this time highlighting different wetland types. The ecological spread in types bog, swamp and fen are very different. Again as demonstrated in the 1D NMDS the bog plots are mores similar in composition regardless to side of road than either swamp or fen. |
