Figure 11: The effects of soil moisture on habitat selection were tested by producing wet and dry areas and then comparing the movement patterns of the lizards.  1.3 cm diameter irrigation drip line was used to moisten the soil to a depth of ~10 cm, 24 hours before the start of the experiment.  The array consisted of a 12.5-m long irrigation hose with six additional 3-m long irrigation segments placed at 90^o on alternating sides of it (3 each side).   Three randomly chosen segments were fitted with plugs, so that no water flowed from them (dry) the other three were fitted with emitters (wet).
