Minimum calling altitudes of Cophixalus frogs on Thornton Peak, Northeastern Queensland

Hoskin, C. J.;Higgie, M.

Abstract

[Extract] The mountain-top fauna of the Wet Tropic region of NE Queensland are predicted to be particularly vulnerable to increased temperatures associated with global climate change (Williams et al., 2003). Bioclimatic modelling has revelaed the Cophixalus frogs to be the most severely threatened vertebrate group in the Wet Tropics (Williams et al., 2003). Future monitoring of the Cophixalus frogs requires, amongst other things, knowing the current altitudinal range boundaries of species (Hoskin, 2004; Shoo & Williams, 2004). Many of these range boundaries have recently been clarified (Hoskin, 2004; Shoo & Williams, 2004) compared to earlier estimates (Zweifel, 1985; McDonald 1992), but several gaps remain. In particular the altitudinal range boundaries of the two Cophixalus species found on Thornton Peak remain poorly known.
