As the fact that carotenoids have immunostimulant properties became more widely known among ecologist, many other interesting "antioxidants and immunity in ecology" papers began to appear (e.g., transfer of antioxidants to the egg, antioxidant-dependent signalling by nestlings to parents, carotenoid- vs. melanin-dependent sexual signals, etc).
