Foraging mode in lacertid lizards: variation and correlates

Abstract Foraging strategy was observed in five species of Israeli lacertid lizards in the field. Acanthodactylus scutellatus is a sit-and-wait strategist, whereas A. boskianus, A. schreiberi, Lacerta laevis and Mesalina guttulata forage widely. However, the actual values differed from those reporte...

Description
Summary:Abstract Foraging strategy was observed in five species of Israeli lacertid lizards in the field. Acanthodactylus scutellatus is a sit-and-wait strategist, whereas A. boskianus, A. schreiberi, Lacerta laevis and Mesalina guttulata forage widely. However, the actual values differed from those reported by Huey and Pianka (1981) for Kalahari lacertids, possibly indicating the existence of a continuum of foraging modes. Foraging intensity (proportion of time spent moving or frequency of moves) is positively correlated to relative tail length, and negatively correlated to relative clutch mass. Additional possible correlates are discussed, and some cautionary remarks added.
