    Abstract

    Ranidella signifera and R. parinsignifera are broadly sympatric in SE Australia. Somatic energy reserves contribute relatively little to energy requirements, so that feeding at breeding sites is essential to finance observed reproductive activity. Males expend about as much on annual reproduction as do females of a variety of small reptiles and amphibians. Food limitation is likely to occur in sympatric populations, though neither food nor microhabitat segregation occurs.
