Abstract:	1. 1.\|Selected body temperatures (SBT) of adult male, female and subadult Lacerta vivipara from a Belgian population, were measured monthly in a laboratory thermogradient. 2. 2.\|Monthly mean SBTs varied between 29.9 and 34.0°C and differed significantly among months in all three lizard groups, and among lizard groups in 4 out of 6 months. 3. 3.\|Evidence for a positive relationship between monthly SBT and air temperature was found in the subadults, but not in the adult lizards. 4. 4.\|Monthly mean SBTs measured in this study were consistently higher (mean difference = 2.0°C) than those obtained by Patterson and Davies (1978) in a similar study on Lacerta vivipara from southern England. Author Keywords: Selected body temperature; behavioural thermoregulation; Lacerta vivipara; intraspecific variation in body temperature
