Would lizards in open habitats exhibit different escape behaviors than lizards in shaded forest?
Very possibly. How fast a lizard runs is a function of its body temperature. Researchers have shown that lizards in shaded habitats have lower temperatures and thus lower maximal running speeds. In such circumstances, lizards often adopt alternative escape tactics that rely less on rapidly running away from potential predators. FIGURE 53.11 The relationship between body size and generation time. In general, larger animals have longer generation times, although there are exceptions. If resources became more abundant, would you expect smaller or larger species to increase in population size more quickly? Answer: Because of their shorter generation times, smaller species tend to reproduce more quickly, and thus would be able to respond more quickly to increased resources in the environment.
