FIG. 4 in Systematics of the Stripetail Darter, Etheostoma kennicotti (Putnam), and the Distinctiveness of the Upper Cumberland Endemic Etheostoma cumberlandicum Jordan and Swain

FIG. 4. Morphological disparity in Etheostoma kennicotti sensu lato and Etheostoma cumberlandicum. (A) Plot of first and second principal component scores of meristic traits in Etheostoma kennicotti sensu lato and Etheostoma cumberlandicum. (B) Mahalanobis distances of PC scores for contrasts of species in the Etheostoma kennicotti complex. In each comparison, the red and blue lineages on the cytb phylogeny are contrasted. A lineage that is a dashed branch is not included in the contrast. The comparison between the upper (U.) Tennessee and lower (L.) Tennessee River is considered an intraspecific contrast.
