While working in Puerto Rico, Paul E.Hertz and his students studied a second species of lizard, the yellow-chinned anole, Anolis gundlachi, using the procedures described in Figure 1.16.Their results for copper models and living lizards are in the Figure.Based on these data, do you think that A.gundlachi regulates its body temperature? Why or why not? 11eb5caa_27ef_1e33_9f04_9947d083acdc 11eb5caa_27ef_1e34_9f04_ff3a12e3f1f4

The hypothesis to be tested is if Anolis gundlachi regulates its body temperature. Anolis gundlachi is a medium-sized and brown colored lizard with irregular pattern on the surfaces of their parts of the body.
The experiment performed to test the hypothesis involves the use of copper lizard models. Copper lizard models are artificial lizard like thermometers. Copper lizard models are kept at random places in shade and in sunlight area, which are mostly inhabited by A. gundlachi.
The data is obtained on the behavior of A. gundlachi to perch in shade or sun-lit area. Also, data for its body temperature is obtained. These data observations are compared with copper lizard model.
The result for the observation on the perching sites of the lizard and copper model shows that the live lizards are mostly found in shade. The copper models are randomly kept in both shaded as well as in sun-lit area.
The result for the body temperature analysis of both live and copper model shows that the body temperature of live and copper model are in the similar range with no significant difference. The body temperature of copper model is significantly influenced by the environmental temperature in shaded and sun-lit area.
These live lizards perch majorly in shaded cold regions and their body temperature is not very significantly different or less then the temperature of copper models that were kept at random in both shaded as well as sun-lit area.
Hence, the conclusion can be drawn that A. gundlachi regulates their body temperature irrespective of constantly perching in the cold shaded area. Hence, the hypothesis holds true.
