Select allometric relationships of female (open circles, dashed line) and male (closed circles, solid line) <i>Hadrurus arizonensis</i>.

<p>A–F depict static allometric scaling relationships of select body characters with metasoma segment 1 width (Met 1 W) as the reference character. A. Prosoma length (Pro L) plot illustrates a difference in y-intercept between the sexes. B. Chela height (Chela H) illustrates no difference between the sexes. C. Telson width (Tel W) illustrates a difference in slopes between the sexes. D–F Illustrate differences in both y-intercept and in shifts along the slope for metasoma length (Met L), total length (Tot L), and pectine length (Pec L). Scales are logarithmic. N = 84–90 females and 65–83 males. Additional details are supplied in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0120392#pone.0120392.s004" target="_blank">S3 Table</a>.
