Effects of Oil Pollution on Body Size and Weight of the Sand Lizard Acanthodactylus scutellatus at the Greater Al-Burgan Oil Field in Kuwait

M. Al-Hashem and P.F. Brain    

Abstract: This study investigated the impact of oil pollution on morphological measurements in adult male and female sand lizards captured in locations with apparently different pollution levels. The results of this study confirmed that there is sexual dimorphism in body size, with males being generally larger than females at all the study sites. Adult male (but not female) lizards were generally bigger at the Tar mat and soot than the clear and control sites. The increase in body size and weight suggests that there is a greater availability of food for these somewhat territorial reptiles in both the Tar mat and soot sites. An alternative explanation is that the food resource is affected by oil pollution such that lizards consuming prey with high levels of fat accumulate more adipose tissue in their bodies.
