Appendix A. Invertebrate responses to urbanization in the nine metropolitan areas based on EPT richness (EPT), ordination scores (NMDS), and organism tolerances (RICHTOL) summarized as linear and loess regressions and compared with change points defined by TITAN analysis.
Invertebrate responses to urbanization in the nine metropolitan areas based on EPT richness (EPT), ordination scores (NMDS), and organism tolerances (RICHTOL) summarized as linear and loess regressions and compared with change points defined by TITAN analysis
Interaction of riparian wetlands and average March runoff (mm) on RichTOL for N.E Highlands BRT model.
<p>Boosted regression tree partial dependency plot shows the response form of average taxa tolerance (y-axis  =  fitted function of RichTOL) based on the effect of the interaction of two individual explanatory variables along the response variable (all other variable responses removed). There is a relatively large interaction at high values of average March runoff when there are also high values of percent riparian wetland thus resulting in higher values of tolerant taxa (RichTOL) than would be expected. We believe that high values of riparian wetland are acting as a surrogate for high values of percent urban land use.</p
Interaction of manmade streams and mean elevation on RichTOL for Northern Piedmont BRT model.
<p>Boosted regression tree partial dependency plot shows the response form of average taxa tolerance (y-axis  =  fitted function of RichTOL) based on the effect of the interaction of two individual explanatory variables along the response variable (all other variable responses removed). There is a relatively strong interaction acting on RichTOL at low values of mean elevation and high values of percent manmade streams that cause high values of tolerant taxa to occur. This is a common pattern, higher urbanization occurring in the lower elevation valleys.</p
