Climate profiles generated bv BIOCLIM6 for three species of lizards in the genus Tiliqua (T. scincoides, T. nigrolutea and T. rugosa), within New South Wales. Predicted distributions produced from these profiles were similar to previously published distributions for each species. Tiliqua scincoides and T. rugosa are almost equal in their temperature requirements which are higher than those for T. nigrolutea. Higher precipitation defines the distribution both T. scincoides and T. nigrolutea with the latter having the higher minimum precipitation values. Tiliquanugosa appears restricted by the association of maximum temperature and precipitation and minimum temperature during cooler months. Tiliqua nigrolutea is limited by minimum precipitation to areas of higher elevation where summers and winters are comparatively cooler and appears the most temperature-sensitive species. Tiliqua scincoides appears restricted by minimum precipitation and minimum temperature but inhabits the widest range of environments from the east coast to central New South Wales. Tilqua scinoides has the widest range of values for climatic parameters, suggesting that it is the least sensitive to climatic factors.
