Table S5: Eigen values, loadings, and scoring coefficients from a Discriminant Function Analysis (DFA) on 9 acoustic parameters
measured from calls recorded from male Pseudacris crucifer in allopatry and sympatry during 2003-2011. For 6 of these we used
residuals from separate regressions on temperature (Table S4). Also included is a DFA of 9 acoustic parameters controlling both for
body size (SVL) and temperature. A ‘t’ denote acoustic parameters that were corrected for temperature for the first DFA, and an ‘m”
indicates which were corrected for body size as well for the second DFA.
