WHAT HAVE WE LEARNED ABOUT THE LIFE CYCLE OF RADIO GALAXIES FROM NEW RADIO SURVEYS




Free radical exposure creates paler carotenoid-based ornaments: a possible interaction in the expression of black and red traits.

Oxidative stress could be a key selective force shaping the expression of colored traits produced by the primary animal pigments in integuments: carotenoids and melanins.However, the impact of oxidative stress on melanic ornaments has only recently been explored, whereas its role in the expression of carotenoid-based traits is not fully understood.
