... for the encoding of social signals versus preferences for those signals. Torus semicircularis Mating preferences Preoptic area Norepinephrine Species recognition Social preferences enable animals to selectively interact with some individuals over others and such preferences underpin a range...

... in the plains spadefoot toad ( Spea bombifrons ), a species in which diet affects the developmental emergence of species recognition and body condition affects the expression of adult mating preferences. To do so, we manipulated the diet of juveniles for 6 weeks following metamorphosis and collected...

... the cowbird chatter: a non-learned vocal cue. We explored the neural basis of such password-based species recognition in juvenile and adult male cowbirds. We found that cowbird auditory forebrain regions express greater densities of the protein product of the immediate-early gene ZENK in response...

...: The stereotypical visually guided mating approaches of male buprestid beetles include two stages that use different spectral cues. Buprestidae Color vision Crypsis Flight Species recognition For arthropods, there have been extensive studies regarding the role of color preferences with respect...

...V. Fugère; R. Krahe SUMMARY Gymnotiformes are South American weakly electric fish that produce weak electric organ discharges (EOD) for orientation, foraging and communication purposes. It has been shown that EOD properties vary widely across species and could thus be used as species recognition...

... to a lack of recognition will require testing with playback experiments. This study is the first to investigate sex and species recognition in otariids based on vocalisations and employing playback experiments. Male vocal recognition was compared in and out of the breeding season when male...

... complexity in ant hydrocarbon recognition cues, we studied the species recognition response of two ant species, Linepithema humile and Aphaenogaster cockerelli , and the recognition of conspecifics by L. humile . The cuticular hydrocarbons of ants are composed of molecules of varying chain lengths from three...
