By examining the mechanical properties of the tympanum of the noctuid moth, Noctua pronuba, Windmill et al. (2006) suggested that this insect increases (up-tunes) the frequencies of its best hearing when exposed to high intensity sounds (HIS) ... Read more...
Echo amplitude selectivity of the bat is better for expected than for unexpected echo duration.

A previous study shows that most inferior collicular neurons of the bat discharge maximally to a best duration and these duration-selective neurons have better echo frequency selectivity when the duration of both echo and pulse matches the best ... Read more...

The origin and maintenance of intraspecific variation in vocal signals is important for population divergence and speciation. Where vocalizations are transmitted by vertical cultural inheritance, similarity will reflect co-ancestry, and thus vocal ... Read more...
