Testosterone control of male courtship in birds.
A sequence of behaviours which we call courtship initiates reproduction in a large number of species. In vertebrates, as a component of male sexual behaviour courtship is strongly influenced by testicular androgen. Here I will review some salient issues about the regulation of courtship by testosterone in birds. The first section will briefly summarize the first 100 years of research on this to...
متن کاملCourtship behavior in Drosophila melanogaster: towards a ‘courtship connectome’
The construction of a comprehensive structural, and importantly functional map of the network of elements and connections forming the brain represents the Holy Grail for research groups working in disparate disciplines. Although technical limitations have restricted the mapping of human and mouse 'connectomes' to the level of brain regions, a finer degree of functional resolution is attainable ...
متن کاملTap dancing birds: the multimodal mutual courtship display of males and females in a socially monogamous songbird
According to classical sexual selection theory, complex multimodal courtship displays have evolved in males through female choice. While it is well-known that socially monogamous songbird males sing to attract females, we report here the first example of a multimodal dance display that is not a uniquely male trait in these birds. In the blue-capped cordon-bleu (Uraeginthus cyanocephalus), a soc...
متن کاملMale Courtship Behavior in Drosophila
All animals exhibit innate behaviors that are specified during their development. Drosophila melanogaster males (but not females) perform an elaborate and innate courtship ritual directed toward females (but not males). Male courtship requires products of the fruitless (fru) gene, which is spliced differently in males and females. We have generated alleles of fru that are constitutively spliced...
متن کاملRunning head : Gift Giving in Courtship Gift Giving as Costly Signaling in Courtship Contexts
Social scientists from a variety of fields have grappled with questions about why gift giving exists and where its utility comes from because it is economically inefficient. Economic models of sexual relationships (e.g., Baumeister & Vohs, 2004) propose that gifts given by men are motivated by attempts to barter for access to sex. We offer an alternative model, based on costly signaling theory ...
