题目材料：
Lizards in New Mexico presented a biological puzzle: those living at lower elevations are smaller than those higher up, even though conventional wisdom held that the cooler climate at high elevations should retard physiological growth. Suspecting that the more desert-like environment lower down constrains the lizards' growth and reduces their foraging activity, biologists decided to study how the lizards cope with the heat. Simulations and subsequent field studies showed that the hot sun did limit lizard activity, but in a more complex way than researchers had assumed. The limitations imposed by heat depended significantly on the distribution of shade in the lizards' environment. In particular, the multiple small patches of shade and sun present at higher, cooler elevations favored the animals' ability to thermoregulate.
