From: Acute Physiological Stress and Mortality Following Fire in a Long-Unburned Longleaf Pine Ecosystem
Post-hoc segmented regression of forest floor consumption effects on longleaf pine sap flux. The post-fire sap flux data are presented as a percentage of mean pre-fire sap flux. Living trees are indicated by filled triangles (▲), trees suffered delayed mortality by open circles (○). The estimated breakpoint was 31.3 % forest floor consumption. The left segment had a slope of −2.8 and the right 0.0 with the R 2 of the entire analysis being 0.677. Also shown are the 90 % confidence block for the breakpoint (rectangle) and the 90 % confidence belt for the regression (dashed lines).
