Defending as a unit: sex- and context-specific territorial defence in a duetting bird

The paper investigates sex- and context-specific territorial defence in rufous horneros using structural equation modelling and simulated territorial intrusion, finding a shared latent trait and positive correlation between sexes.

Acute aggressive behavior perturbates the oxidative status of a wild bird independently of testosterone and progesterone

The paper tests if acute aggression affects oxidative status in birds, finding lower non-enzymatic antioxidants in both sexes after aggression, independent of hormone levels.

Female variation in allocation of steroid hormones, antioxidants and fatty acids: a multilevel analysis in a wild passerine bird

The paper analyzes variation in steroid hormones, antioxidants, and fatty acids in great tit egg yolks across laying sequences and population levels, finding differences in allocation patterns and female repeatability.

Not one hormone or another: Aggression differentially affects progesterone and testosterone in a South American ovenbird

The paper investigates how territorial aggression affects progesterone and testosterone levels in male ovenbirds during different breeding stages, finding differential hormonal responses and consistent ratio changes.
