Table 2.
A summary of the effects of cricket size, age, body condition, temperature, and acclimatisation on the calling behaviours and call parameters of L. luae. ‘ + ’ represents a strong positive effect of the factor on a calling behaviour or call parameters; ‘ − ’ represents a strong negative effect; ‘Quadratic’ represents a strong quadratic effect. The intra-class coefficient (ICC) and standard errors for each trait are also provided as an estimate of relative repeatability
