eco photo 2

This photo shows what I think is a Carolina anole (Anolis carolinensis) lizard sunbathing on the front steps of Dobo hall. He/she is doing so because lizards are ectothermic meaning that they acquire heat from an outside source because they can not produce it themselves. They do this because they have to maintain homeostasis.This acquisition of energy is a product of the fundamental concept called scaling. This contributes to a predictable manner in which their physiological and morphological features promote their ectothermic regulations. For example, the anoles have very long slender bodies and according to the fundamental concept of scaling, this small and cylinder like body maximizes the surface area relative to volume ratio. This promotes them capturing as much sunlight as possible. The interplay of morphological and physiological features promotes the lizards saving energy by not having to produce their own heat. This leads to a fundamental trade-off due to their constraint to regions that on average receive more sunlight than places far North or South. This need for sunlight acts as a constraint to their geographical range. This restricts the anoles to the Southern regions of the United States.
