The important role that mate choice plays in the lives of animals is matched by the large and
active research field dedicated to studying it. Researchers work on a wide range of species …

Mate choice hypotheses usually focus on trait variation of chosen individuals. Recently,
mate choice studies have increasingly attended to the environmental circumstances …

Females use multiple cues from different sensory modalities to choose males of high
phenotypic or genetic quality to mate with. Fish may use visual and acoustic communication …

Our understanding of sexual selection has greatly improved during the last decades. The
focus is no longer solely on males, but also on how female competition and male mate …

Phenotypically plastic mating behavior may allow males to modify their reproductive
behavior to suit the prevailing social conditions, but we do not know if males only react to …

Many animals exhibit social plasticity–changes in phenotype or behaviour in response to
experience with conspecifics that change how evolutionary processes like sexual selection …

Highlights•We examine how energy balance/social context affect display effort in singing
mice.•We injected mice with leptin or saline before or after exposure to conspecific …

Intraspecific trait variation, including animal personalities and behavioural syndromes,
affects how individual animals and populations interact with their environment. Within …

Observations of male mate choice are increasingly common, even in species with traditional
sex roles. In addition, female traits that bear the hallmarks of secondary sexual characters …

Very few studies have presented compelling evidence for adaptive shifts in female mating
preferences. Additionally, there is almost no data on how males adjust courtship effort when …
