Behavior of wild vertebrate individuals can vary in response to environmental or social
factors. Such within-individual behavioral variation is often mediated by hormonal …

Sexually dimorphic behaviors, qualitative or quantitative differences in behaviors between
the sexes, result from the activity of a sexually differentiated nervous system. Sensory cues …

Recent research has analyzed how individual characteristics, like the exposure to different
hormones and symmetry, affect decision-making and strategic behaviour. The present article …

Testosterone is a key hormone for the development of secondary sexual characters and
dimorphisms in behavior and morphology of male vertebrates. Because females often …

Androgens are pleiotropic and play pivotal roles in the formation and variation of sexual
phenotypes. We show that differences in circulating androgens between the three male …

Testosterone (T) is thought to play a key role in male–male competition and courtship in
many vertebrates, but its precise effects are unclear. We explored whether courtship …

Males of many animal species perform specialized courtship behaviours to gain copulations
with females. Identifying physiological and anatomical specializations underlying …

Birds have long been used as models to investigate the regulation of male reproductive
processes and in particular of testicular function. In many species, the exocrine and …

A central goal in evolutionary ecology is to characterize and identify selection patterns on
the optimal phenotype in different environments. Physiological traits, such as hormonal …
