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) ...

Echo amplitude selectivity of the bat is better for expected than for unexpected echo duration.
24 Aug 2009 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 ...

17 Aug 2009 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 ...

Context-dependent effects of noise on echolocation pulse characteristics in free-tailed bats.
10 Aug 2009 Background noise evokes a similar suite of adaptations in the acoustic structure of communication calls across a diverse range of vertebrates. Echolocating bats may have evolved specialized vocal strategies for echolocating in noise, but also seem ...

15 Jul 2009 In response to sonar-guided attacking bats, some tiger moths make ultrasonic clicks of their own. The lepidopteran sounds have previously been shown to alert bats to some moths' toxic chemistry and also to startle bats unaccustomed to sonic prey. ...

Acoustic effects accurately predict an extreme case of biological morphology.
12 Jul 2009 The biosonar system of bats utilizes physical baffle shapes around the sites of ultrasound emission for diffraction-based beam forming. Among these shapes, some extreme cases have evolved that include a long noseleaf protrusion (sella) in a species ...

Development of auditory thalamocortical connections in the pallid bat, Antrozous pallidus.
8 Jul 2009 
Auditory thalamocortical connections are organized as parallel pathways originating in various nuclei of the medial geniculate body (MGB). The development of these pathways has not been studied. Therefore it remains unclear whether thalamocortical ...

What a plant sounds like: the statistics of vegetation echoes as received by echolocating bats.
Jul 2009 A critical step on the way to understanding a sensory system is the analysis of the input it receives. In this work we examine the statistics of natural complex echoes, focusing on vegetation echoes. Vegetation echoes constitute a major part of the ...

Naïve bats discriminate arctiid moth warning sounds but generalize their aposematic meaning.
29 Jun 2009 Naïve red (Lasiurus borealis Müller) and big brown (Eptesicus fuscus Beauvois) bats quickly learn to avoid noxious sound-producing tiger moths. After this experience with a model tiger moth, bats generalize the meaning of these prey-generated sounds ...

29 Jun 2009 Although the potential of using portable auditory evoked potential systems for field testing of stranded cetaceans has been long recognized, commercial systems for evoked potential measurements generally do not possess the bandwidth required for ...
