I used ArcGIS Pro to explore whether there is a correlation between elevation and leaf litter in the US Northern Appalachian region within the range of Plethodon cinereus (red-backed salamander). Leaf litter abundance may help us better understand a recognized elevation-based distribution of the two P. cinereus morphs. Using the “Band Collection Statistics” tool, I calculated the correlation coefficient between elevation and leaf litter. The results show a correlation coefficient of 0.31314. This corresponds to a low positive correlation between elevation and litter carbon. This implies that leaf litter could be a factor driving the higher frequency of striped P. cinereus at higher elevations, but more work is needed to prove that.
