Oxidative physiology is weakly associated with pigmentation in birds
Ecology and Evolution, 2022 The mechanistic link between avian oxidative physiology and plumage coloration has attracted considerable attention in past decades. Hence, multiple proximal hypotheses were proposed to explain how oxidative state might covary with the production of ...

A quantum yield map for synthetic eumelanin [PDF]
The Journal of Chemical Physics, 2005 The quantum yield of synthetic eumelanin is known to be extremely low and it has recently been reported to be dependent on excitation wavelength. In this paper, we present quantum yield as a function of excitation wavelength between 250 and 500nm, showing it to be a factor of 4 higher at 250nm than at 500nm.
