Abstract:
Sound communication, by means of substrate-borne vibrations, was recorded and analysed from a Slovenian and Australian population of the pentatomid landbug, Nezara viridula. Mate location and short-range courtship in N. viridula involves the recognition of such species-specific signals and responding appropriately to them. Temporal parameters of all N. viridula song types differed considerably between males and females of the two populations. In particular, the female calling song, which enables Slovenian male bugs to locate the female on a host plant, was significantly different. The song repertoire from a Slovenian and Australian population and the species status of N. viridula are discussed.

Testing a Claim about Mean: Unknown Population SD
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used;...

Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...
