FIGURE 4 in Lacunicambarus chimera: a new species of burrowing crayfish (Decapoda: Cambaridae) from Illinois, Indiana, Kentucky, and Tennessee

FIGURE 4. Non-metric multidimensional scaling (NMDS) plot for Form II males (n = 25) showing differences in morphological and meristic characters between Lacunicambarus chimera and L. diogenes. Vectors represent strength and direction of correlation of each character relative to the NMDS axes. This NMDS converged on a two-dimensional solution with an acceptable stress level (non-metric fit R2 = 0.99; linear fit R2 = 0.97; stress = 0.07). Abbreviations: L, length; W, width; CP, central projection; MP mesial process.
