Importance of melanin-based colouration and environment in shaping intracellular glutathione levels in nestling and adult tawny owls (Strix aluco)

Guillaume Emaresi, Pierre Bize & Alexandre Roulin
Resources allocated in reproduction are traded off against those invested in self-maintenance such as antioxidant response. Glutathione (GSH) is an intracellular antioxidant defence that scavenges reactive oxygen species, the deleterious byproducts of oxygen consumption. Given the role of intracellular GSH in pheomelanogenesis, a trade-off in GSH allocation between resistance to oxidative stress and melanin production may take place. To investigate how intracellular GSH is regulated in differently coloured individuals at the time of reproduction (in...
