Frogs Have Rules: Selective Attention Algorithms Regulate Chorusing in Physalaemus pustulosus (Leptodactylidae)

摘要: In various acoustic insects and frogs, females preferentially orient towards the leading of two or more males' advertisement signals that occur closely in time. Such preferences receivers have apparently selected for timing mechanisms whereby male signallers actively refrain from calling immediately following onset a neighbour's call thereby increase their production calls. However, indiscriminate application this inhibitory mechanism to all neighbours might severely reduce male's rate, particularly high density. Consequently, selective attention only subset signalling are expected. Female Tungara frogs (Physalaemus pustulosus) exhibit strong calls, males neighbour. Four-loudspeaker playback experiments demonstrated do selectively apply close neighbours. Selective is regulated by combination sliding threshold fixed number rules: (i) Attend loudest (nearest) conspecific neighbour those additional ones whose calls within 6–8 dB one; (ii) attend total when weak second one much farther than first; (iii) three loud approximately equidistant. The means which such plasticity may be achieved its potential adaptiveness discussed.
