Power output and efficiency of sound production by crickets

Forrest, T. G.·1991·Behavioral Ecology

Abstract

I estimated the sound power of male crickets calling outdoors using a microphone array to measure their sound fields. Average power output for four species, Scapteriscus borellii (N = 18), S. vicinus (N = 7), Oecanthus quadripunctatus (N = 6), and Anurogryllus arboreus (N = 6), was 6.5, 4.5, 10.2, and 58.6 μW, respectively. Power output for male mole crickets (Scapteriscus spp.) was variable (range 2–22 nW), and estimated efficiency was less than 0.1%. Efficiencies of sound production for tree crickets {Oecanthus) and short-tailed crickets (Anurogryllus) were between 1% and 3%. Power output of S. vicinus males was significantly correlated with soil moisture near the male's burrow. Larger Oecanthus males produced significantly more power than smaller males. Male Oecanthus that used leaves as baffles increased power output by a factor of 2 (3 dB). Radiation patterns of Scapteriscus sound fields were hemispherical. Those of Oecanthus and Anurogryllus were dumbbell shaped. Radiation patterns of Scapteriscus and Oecanthus are predicted by simple physical systems. The costs and benefits to male reproduction due o increased power output relate to changes in efficiency of sound production and preferences used by females, competitors, or natural enemies in locating calling males.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The asynchronous, two-microphone method allows for fine spatial resolution in mapping acoustic fields and has been used to reconstruct complicated radiation patterns.

    “This asynchronous, two-microphone method allows for fine spatial resolution in the mapping of acoustic fields and has been used to reconstruct some very complicated radiation patterns (Au et al., 1995; Bennet-Clark, 1987; Forrest, 1991; Hartley and Suthers, 1987, 1989, 1990; Hunter et al., 1986; Larsen and Dabelsteen, 1990).”
  • When the intended receiver's position is unknown, directional display can be a liability necessitating continual modification of display posture to maximize the probability of reception.

    “When the intended receiver's position is unknown, however, directional display can be a liability necessitating continual modification of display posture to maximize the probability of reception (Forrest, 1991).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
