Ecological parameters of the eight populations where individuals were collected during the reproductive season of 2010 for quantification of physiological parameters.

<p>These parameters include andromorph frequencies (%) and male density (individuals/minute), based on summed immature and mature individuals, as well as annual temperature (°C) and precipitation (mm) normals. Site numbers correspond with the numbers in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0032648#pone-0032648-g001" target="_blank">Figure 1</a>.
