Length and weight data.

<div><p>(a) A histogram of total length (TL) data for this study (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0078740#pone-0078740-t002" target="_blank">Table 2</a> for related statistics).</p> <p>(b) A histogram of weight data for this study (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0078740#pone-0078740-t002" target="_blank">Table 2</a> for related statistics).</p> <p>(c) A non-linear regression curve of log weight on TL.</p> <p>[LogW=a+bL+cL²; a=0.320, b=0.00022, c=-3.347e-006; R²=0.951; Sy.x=0.064; for other related statistics see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0078740#pone-0078740-t002" target="_blank">Table 2</a>].</p> <p>(d) A seasonal comparison of L:W relationships. Large, sexually differentiated animals are heaviest in the fall and lightest in the winter. </p> <p>[LogW=a+bL+cL²; Summer: a=0.802, b=0.004, c=-2.012e-006, <i>n</i>=69, R²=1.00.</p> <p>Fall: a=1.081, b=0.003, c=-3.486e-007, <i>n</i>=15, R²=0.999.</p> <p>Winter: a=0.090, b=0.007, c=-3.927e-006, <i>n</i>=126, R²=0.995.</p> <p>Spring: a=0.745, b=0.005, c=-3.310e-006, <i>n</i>=179, R²=0.992.</p> <p>F_(9,901)=3.903e+012; p<0.05*, curves are significantly different].</p>
