TABLE 4. Temporal and spectral parameters in the advertisement calls of Mantidactylus noralottae, M. betsileanus and M. sp. aff. ulcerosus. Temporal data are given as range, followed (in parentheses) by mean ± standard deviation and number of measured elements. Comparative calls of M. betsileanus and M. sp. aff. ulcerosus taken from Vences et al. (2006), while further data in parentheses follow Glaw & Vences (1994).
