Caenorhabditis elegans male mating provides an excellent opportunity to determine how sensory perception regulates behavior and motor programs. The male-specific nervous system and muscles are superimposed over the general nervous system and musculature. Genetic screens and genomic approaches have identified male-specific and male-enriched genes as well as non-sex specific molecules specialized...

Ecological research in the past few decades has shown that most animals acquire and respond adaptively to information that affects survival and reproduction. At the same time, neurobiological studies have established that the rate of information processing by the brain is much lower than the rate at which information is encountered in the environment, and that attentional mechanisms enable the ...

are displayed prominently in intraspecific interactions, such as aggressive or mating behavior. These animals thus use patterns of polarized light in the same way that other species use color patterns, providing a unique and therefore unmistakable appearance to visual systems capable of analyzing polarization patterns. Also, since the polarization pattern is independent of the spectrum of illum...

The display of courtship behavior has evolved in response to sexual selection driven by competition to obtain mates. Sexually dimorphic mate selection rituals are likely controlled at least in part by genes with sex-biased patterns of expression. In Drosophila melanogaster, male courtship behavior has been well described and consists of a series of stereotyped behaviors. The takeout gene is pre...

The mate choices of children do not always meet with the approval of their parents. As a consequence, the latter employ a battery of tactics that they use to manipulate the mating behavior of the former. This paper offers the first taxonomy of parental tactics of mate choice manipulation. In particular, in Study 1, 57 semi-structured interviews revealed 72 acts that parents employ to influence ...
