Geographic variation in field body temperature of sceloporus lizards

Using data from the literature, I assessed how broad climatic patterns aAected field body temperatures (Tb's) of lizards in the genus Sceloporus. 2. Sceloporus at temperate latitudes had mean Tb's of 358C throughout their elevational range. This pattern is associated with ''tropical'' temperatures that extend into high north latitudes during the sum- mer and the relatively low elevations occupied by the lizards. 3. At tropical latitudes, mean Tb declined from 358C at low elevations to 318C at high elevations. This pattern is associated with low seasonal variation in temperature at tropical latitudes and the rela- tively high elevations occupied by the lizards. # 1998 Elsevier Science Ltd.
