Saving Water to Survive: Alternative Water Loss Strategies Could Explain Color Polymorphism Maintenance in a Lacertid Lizard

Integrative Zoology, EarlyView.
We demonstrate that red male Podarcis muralis exhibit higher evaporative water loss compared to other morphs, indicating a physiological strategy that prioritizes hydroregulation over fine thermoregulation. This suggests red morphs are adapted to cooler, wetter niches, while white and yellow morphs possess superior water conservation mechanisms to ...

Resonance Raman spectroscopic measurement of carotenoids in the skin and retina

Journal of Biomedical Optics, 2005
Carotenoid pigments within the skin and retina are measured using resonance Raman spectroscopy (RS). These RS instruments are unique in that they have been designed to obtain vibrational spectra in normal and diseased subjects using noninvasive procedures. Raman spectra have traditionally been used as a means of identifying a given chemical within some
