Diverse dose-response effects of yolk androgens on embryo development and nestling growth in a wild passerine.

The Journal of experimental biology - 1 Jul 2015

Muriel Jaime, Pérez-Rodríguez Lorenzo, Puerta Marisa, Gil Diego

Abstract excerpt

Avian egg yolks contain various amounts of maternally derived androgens that can modify offspring phenotype and adjust their development to the post-hatching environment. Seemingly adaptive variation in yolk androgen levels with respect to breeding density conditions or male attractiveness has been found in numerous studies. One important consideration that has been overlooked in previous research is the likely...
