Black And White: Structural And Functional Aspects Of Dermal Chromatophores Of The Marbled Whiptail Lizard (Cnemidophorus Marmoratus), James Swan

Masters Theses & Specialist Projects

The skin of reptiles is a complex organ with many sensory, regulatory and behavioral functions. Desert reptiles face a suite of challenges as their skin contacts hot-dry environmental surfaces. The marbled whiptail lizard, Cnemidophorus marmoratus (Lacertilia: Teiidae), is found in hot deserts of southeastern New Mexico and western Texas and is often above ground during the hottest times of the day. When active, these lizards encounter a broad range and intensity of visible and infrared wavelengths. The role of the integument in temperature regulation, although poorly understood, is critically important for these diurnal animals. Albedo, coloration, pattern, and in some …
