There is substantial interest of evolutionary ecologists in the proximate mechanisms that modulate vocal communication. In recent times, there has been growing interest in the role of oxidative stress as a mediator of avian song expression.
Here, we tested whether the experimental inhibition of the synthesis of a key cellular antioxidant (glutathione) reduces song rate metrics of male European...
There is considerable interest of evolutionary ecologists in the proximate mechanisms that constrain life‐history variation. It is increasingly recognized that oxidative stress may be a prime physiological constraint on reproduction, but to the best of our knowledge, this has never been tested experimentally.
To fill in this gap, we examined whether a specific and short‐term experimental increase...
