Abstract
A study was conducted at a semi-arid site near Mt Mary, South Australia.
Fifty-eight adult sleepy lizards, Tiliqua rugosa, were
radio-tagged and regularly located over the spring season, when they are most
active, for 2-5 years. Home-range area did not differ between males and
females. Changes in home-range position between years were assessed by the
distance between home-range centres measured at intervals of one, two, three
or four years. Mean distances for successive years were less than the span of
the home range in one year. The distance did not differ between sexes, it was
not related to lizard size, nor did it increase with increased time interval.
This implies that for the resident adult population, lizards retain their home
ranges for at least five years, and that the sexes do not differ in their
fidelity to home range.
