...Second, there is evidence that differences in habitat light conditions have selected for different color patterns in different microhabitats (i.e., selection through the process of sensory drive; Fleishman et al. 1993; Fleishman 2000; Macedonia 2001; Leal and Fleishman 2002)....

...and background, respectively, integrated over 320‐ 700 nm. To calculate chromatic contrast, all radiance spectra of the chameleons and backgrounds were standardized for brightness (area under the curve 320‐ 700 nm = 1). Chromatic contrast was then calculated as the Euclidean distance ( D s ) between the radiance spectrum of the chameleon vs. background (Endler, 1990; Macedonia, 2001; Heindl & Winkler, 2003), using:...
