Energy, calling, and selection

摘要: SYNOPSIS. Acoustic signals often mediate the mating process and are under selection through action of female choice. signalling requires relatively large amounts energy input, but metabolic is coupled to acoustic inefficiently. Although not necessarily a cause effect relationship, females prefer with more energy. Females may intense calls, complicated or calls produced at greater repetition rate. I discuss various evolutionary changes that could increase received by examine how these influenced other factors inherent communication systems: signal radiation, species recognition, sexual selection, physiology receptor system, environmental bioacoustics. conclude constrain ability animal maximize female. then consider two hypotheses, good genes hypothesis runaway hypothesis, attempt explain evolution choice for content.
