The Signaller's Dilemma: A Cost–Benefit Analysis of Public and Private Communication

Abstract: BackgroundUnderstanding the diversity of animal signals requires knowledge of factors which may influence the different stages of communication, from the production of a signal by the sender up to the detection, identification and final decision-making in the receiver. Yet, many studies on signalling systems focus exclusively on the sender, and often ignore the receiver side and the ecological conditions under which signals evolve.Methodology/Principal FindingsWe study a neotropical katydid which uses airborne… Show more

“…3, see also Morris et al 1994). Similar to C. (Belwood, 1988(Belwood, , 1990Belwood and Morris, 1987;Morris et al, 1994;Römer et al, 2010). Eavesdropping seems to explain why some bush-crickets use such bewilderingly high principal carriers (Belwood and Morris, 1987;Falk et al, 2015;Montealegre-Z et al, 2006;Montealegre-Z et al, 2011b;Morris et al, 1994;Sarria-S et al, 2014).…”

“…We also recorded vibrations from a single point at the base of each palm branch, and did not try other locations. Römer et al (2010) showed that the host plant of Docidocercus gigliotosi filters vibrations, depending on the location of the signaller on the plant, and that some parts of the plant enhance the transmission of the vibration. For instance, the leaves seem to act as resonators in the range of 10-15 Hz.…”

“…Multimodal signals allow animals to shift energy between signal components when costs and benefits differ between communication channels [46,50]. Tropical katydids, for example, increase the use of substrate-borne vibrations at the expense of air-borne sounds under full moon light conditions [46]. This behaviour presumably evolved to allow private communication, and thereby avoid the risk of eavesdropping bats [46,51].…”
