The function of concurrent signals: visual and chemical communication in snapping shrimp
Article Abstract:
Male snapping shrimps, Alpheus heterochaelis, respond more to visual signals of open chela with chemical signals from males than from females, whereas females respond similarly to all visual and chemical signals. In the presence of female chemical signals, the response to an open chela depends on the relative size of the open chela of the male receiving the chemical signals. Males fail to respond to any chemical signals in the absence of any other visual signal. For females, factors such as shelter are more important in aggressive behaviour with a competitor.

Why do animals repeat displays?
Article Abstract:
Animal displays often involve the repetition of some specific behavioral action. Three possible explanations for the repetitive action are examined. These reasons are to confirm the message of the earlier actions, to replace the message of the earlier actions and to add to the message of the earlier actions. These possibilities are investigated in the displays of cichlid fish, the roaring of red deer, the calling of Blanchard's cricket frogs and the pheromonal exchanges of yeast gametes.

Receiver psychology and the evolution of multicomponent signals
Article Abstract:
Most animals produce and respond to displays consisting of multiple components. Data from laboratory studies shows that two stimulii are more effective than one in eliciting responses. Detection is improved by producing two components together, reducing reaction time and increasing the probability of detection.
