Figure 5.

Graphical representation of the effect of the two-way interaction term species density × initial density difference. Lines represent the initial density difference: −4 (solid line); 0 (dashed line); 4 (dotted line), where initial density difference ranges from a maximum density in the right-hand patch and no macrofauna in the left-hand patch (−4) to a maximum density in the left hand patch and no macrofauna in the right-hand patch (4). Species density is a percentage of the natural densities found at the study site. As the GLS framework allows for different spreads in the data, individual data points are omitted to prevent misinterpretation.
