摘      要：The thermal ecology of ectotherms has been studied for almost 2 centuries,but additional attention is current­ly being paid to it,to understand how organisms deal with the environment in a climate change context.A con­sensus is still far away due to the large number of factors involved and their complex interactions.In this con­text,3 analyses in lacertid lizards were carried out:(i)a meta-analysis,to test for differences between body and air temperatures from 71 populations;(ii)a meta-analysis concerning correlations between body and air tem­peratures from 60 populations;and(iii)a multimodel inference of thermoregulation effectiveness indices from 45 populations.The importance of different factors,including body size,habitat,insularity,altitude,climate and season,was evaluated in all analyses to model the response variables.A strong seasonality effect was observed,with a consistent pattern of less effective thermoregulation in summer compared to other seasons.Altitude was the second most important factor,with a consistent higher thermoregulation effort in populations occurring at high elevations(1000 m above sea level).Other factors,such as insularity or body size,can also be important,but did not exhibit a clear pattern.Finally,thermoregulation was less affected by climate and habitat type.
