Abstract

The concept of reproductive effort and the problems associated with its measurement in lizards are reviewed and discussed. Many authors use indices such as the Relative Clutch Mass (R.C.M.) which are of limited value. Though not yet in common use, the energy budget approach looks promising, especially since field radioisotope techniques are now available. The role of the energy stored in fat deposits, and of that invested in tail regeneration, is discussed. Both seem able to influence reproductive patterns in lizards. The demographic component of the reproductive effort (i.e. whether the energy is allocated to a few or many offspring), and the relationships between reproductive strategies and environmental and genetic factors, are also considered.
