Ultraviolet Radiation and Carotenoid Pigmentation in Symbiotic Anthozoans
… symbiosis, to investigate 1) the origin of carotenoid pigmentation and the role of carotenoids as ultraviolet radiation (UVR) photoprotectants and 2) the repopulation and photoadaptive response of symbiotic algae (i.e., zooxanthellae) after bleaching. An experiment was conducted to partition …

Evolutionary genetics of CYP2J19 in red carotenoid pigmentation
Carotenoids are responsible for much of the bright yellow to red colours in animals and have been extensively studied as condition dependent signals in sexual selection. In addition to their function in coloration, carotenoids also play a crucial role in colour vision within certain lineages. …

Action of clofazimine on Mycobacterium avium and Mycobacterium intracellulare
… clofazimine in growth medium resulted in higher carotenoid pigmentation in M. avium cells. Carotenoid pigments have been shown to quench superoxide radicals supporting the hypothesis that pigmentation possibly protected cells against superoxide. Clofazimine caused the generation of superoxide …

The Response of Staphylococcus aureus to Culture in a Low-Fluid-Shear Environment
… cells within the biofilm revealed a decrease in carotenoid pigmentation and growth, an increase in susceptibility to oxidative stress, and increased killing by whole blood as compared to controls. In addition, low-shear-cultured S. aureus displayed increased macrophage clearance and a decreased …

The maintenance of variation in Cyprinodontiformes
… coloration in the caudal fin was caused by a carotenoid pigment. Color in the anal fin was either pterin based (yellow and red) or structural (blue) with a melanic fin border. Using a behavioral assay designed to measure dominance, I sought to determine the informational content of each …
