Table 3. Summary and results of statistical comparisons (t Student results) for the 13 bioacoustic characteristics measured in the calls between Scinax altae and Scinax staufferi. Values are reported a mean ± standard deviation, (minimum– maximum). n = Sample size. Statistically significant results (p ≤ 0.05) are highlighted in bold.
