Abstract	Selective poaching of Asian elephant (Elephas maximus) males for ivory has resulted in highly female-biased adult sex ratios, necessitating regular monitoring of population structure and demography. We demonstrate that molecular sexing from dung-extracted DNA, based on ZFX-ZFY fragment amplification and ZFY-specific BamHI site restriction, can be applied to estimate sex ratios of free-ranging Asian elephants, in addition to or instead of field demographic methods. The adult sex ratios using molecular sexing in Nagarahole and Mudumalai-Bandipur reserves during May 2001 were 1:3.1, which matched the demography-based sex ratio for the same month, and 1:9.4, respectively.
