Busack2 Museum of Vertebrate Zoology, University of California, Berkeley, California 94 720, USA Introduction Most lizards can autotomi ze the tail when attacked by predators (Etheridge, 1967) and Rand (1 954) was among the first to use the frequency of tail loss in a lizard population as an estimate of the level of predation upon lizards (see Pianka, 1967). To date , the only evidence for this assumed relationship is that reported by Pianka (1 970) who showed that tail-loss figure s were higher in areas where more potential predators were observed. Pianka' s assumption was that the occurrence of a greater number of predators results in more lizard/predator,encounters. Althoug h not unreasona ble , this assumption does require that those areas with more numerous pre dators actually contain predators that eat lizards. If these predators do not prey upon lizards, or if they prey upon lizards only in negligible amounts, counting potential predators will not adequately estimate predation risk to lizards. A more adequate assessment of the
