Interspecific associations between circulating antioxidant levels andl life-history variation in birds

Cohen, Alan A.; McGraw, Kevin J.; Wiersma, Popko; Williams, Joseph B.; Robinson, W. Douglas; Robinson, Tara R.; Brawn, Jeffrey D.; Ricklefs, Robert E. (2008)

Antioxidants play an important role in protecting tissues against aging-associated oxidative damage and are thus prime candidates for relating physiological mechanisms to variation in life histories. We measured total ...

Simpson, Richard K.; McGraw, Kevin J. (2018)

Many animals communicate using more than one signal, and several hypotheses exist to explain the evolution of multiple signals. However, these hypotheses typically assume static selection pressures, and previous work has ...
