Desert locations in Al-Burgan oil fields of Kuwait were subjected to oil pollution generated by the Gulf war in 1990. Studying sand lizard (Acanthodactylus scutellatus) population and their ant prey in the years 2002 and 2003 to monitor the effects of oil pollution was thought to be useful in an area damaged by oil spill. Sites with apparently different levels of pollution, namely tar mat, soot and clear sites were compared with control sites outside this area. Live specimens of A. scutellatus were collected by drift fence and pitfall traps and were marked by toe clipping and painting bands before they were released. Ant population was collected by removal methods using vacuum. The mark-recapture Schnabel method of population estimation was used. The results revealed no difference in lizard population sizes between the different study sites in 2002 and 2003. A slight difference was observed in ant population sizes between the sites in 2002 but no difference was detected between the sites in 2003. Although, the mean estimated lizard numbers were lowest at the tar mat sites, the ant number in this location was greatest, meaning that food availability was highest at these sites. This suggests any reduction in the numbers of lizards is unrelated to low resource availability. |
