1.

The number of life-history stages does not influence the androgen responsiveness to male-male interactions: Sedentary and migratory black redstarts (Phoenicurus ochruros) do not elevate testosterone in response to simulated territorial intrusions.

Villavicencio CP, Blas J, Goymann W.

Gen Comp Endocrinol. 2014 May 1. pii: S0016-6480(14)00147-6. doi: 10.1016/j.ygcen.2014.04.017. [Epub ahead of print]
