A comparative study of water loss in two geographically and climatically isolated populations of the coastal side-blotched lizard, Uta stansburiana hesperis Richardson

Rates of evaporative water loss were obtained for two geographically and climatically isolated populations of Uta stansburiana hesperis Richardson under specified conditions of temperature, relative humidity and air flow. From these data, equations for the two populations predicting evaporative water loss were derived in an attempt to show: (1) habitat correlation of evaporative water loss and (2) differential, genetically-determined response patterns of evaporative water loss in respect to reproductive isolation. In this study it was found that the rate of water loss in the two lizard populations did not differ significantly in relation to the effects of air temperature, relative humidity and convection.
