“…It stands to reason that such vocalizations are ecologically important and thus tied back to the performance of the inner ear. The frequency range over which OAEs occur matches well to that of the gecko's vocalizations (Marcinelli 1977;Bergevin et al 2010b). In terms of production apparatus, there can be significant morphological variation in vocal tract across gecko species (Russell et al 2000).…”

“…The gecko auditory system appears special amongst lizards (Miller 1973b;Manley 2010): complex papilla structure and TM morphology, "reversed" tonotopic map (Manley et al 1999) and robust emissions (Manley et al 1996;Stewart and Hudspeth 2000;Bergevin et al 2008). Additionally, Gekkota is the only lizard infraorder known to possess elasticized vocal cords (Russell et al 2000) and display spectrally rich vocalizations (Marcinelli 1977;Weber and Werner 1977). Furthermore, there is a significant body of auditory physiological work that has been reported on geckos, such as age-related changes in auditory sensitivity (e.g., Werner et al (1998)), dependence upon body temperature (Campbell 1969;Werner 1976), and various comparative descriptions (e.g., Wever et al (1964);Werner et al (1998);Ganeshina and Vorobyev (2009);Brittain-Powell et al (2010)).…”

“…In one species of gecko (Ptenopus garrulus garrulus), the "dominant call frequency" has been reported to decrease with increasing SVL (Hibbitts et al 2007). Although there are many different types of utterances with varying frequency content (e.g., mating versus territorial calls, single versus multiple "chirps"), spectrograms suggest that smaller gecko species may have energy extending out to higher frequencies than larger species (Marcinelli 1977;Frankenberg 1982). An inverse relationship between body size and the upper limit of relevant frequency content in vocalizations thus appears congruous with the extended frequency range of emissions in the smaller lizards.…”

Comparison of Otoacoustic Emissions Within Gecko Subfamilies: Morphological Implications for Auditory Function in Lizards

Otoacoustic emissions (OAEs) are sounds emitted by the ear and provide a non-invasive probe into mechanisms underlying peripheral auditory transduction. This study focuses upon a comparison of emission properties in two phylogenetically similar pairs of gecko: Gekko gecko and Hemidactylus turcicus and Eublepharis macularius and Coleonyx variegatus. Each pair consists of two closely related species within the same subfamily, with quantitatively known morphological properties at the level of the auditory sensory organ (basilar papilla) in the inner ear. Essentially, the comparison boils down to an issue of size: how does overall body size, as well as the innerear dimensions (e.g., papilla length and number of hair cells), affect peripheral auditory function as inferred from OAEs? Estimates of frequency selectivity derived from stimulus-frequency emissions (emissions evoked by a single low-level tone) indicate that tuning is broader in the species with fewer hair cells/shorter papilla. Furthermore, emissions extend outwards to higher frequencies (for similar body temperatures) in the species with the smaller body size/narrower interaural spacing. This observation suggests the smaller species have relatively improved high-frequency sensitivity, possibly related to vocalizations and/or aiding azimuthal sound localization. For one species (Eublepharis), emissions were also examined in both juveniles and adults. Qualitatively similar emission properties in both suggests that inner-ear function is adult like soon after hatching and that external body size (e.g., middle-ear dimensions and interaural spacing) has a relatively small impact upon emission properties within a species.

“…Such eavesdropping on heterospecific auditory signals has typically been found among species that routinely communicate vocally. Despite the fact that lizards generally have seemingly well-developed ears (Wever 1978), most lizards, except for gekkonids, do not use vocal signals for intraspecific communication (Marcellini 1977;Lopez et al 1998;Pianka & Vitt 2003;Vercken & Clobert 2008). Accordingly, few studies have shown practical roles of ears in free-living lizards.…”

Prey animals can reduce their risk of predation by detecting potential predators before encounters occur. Some animals gain information about nearby predators by eavesdropping on heterospecific alarm calls. Despite having well-developed ears, most lizards do not use vocal information for intraspecific communication, and few studies have shown practical use of the ears in wild lizards. Here, we show that the Madagascan spiny-tailed iguana (Oplurus cuvieri cuvieri ) obtains auditory signals for predator detection. The Madagascan spiny-tailed iguana and the Madagascar paradise flycatcher (Terpsiphone mutata) are syntopic inhabitants of the Ampijoroa dry deciduous forest of Madagascar. The iguana and the flycatcher have neither a predator -prey relationship nor resource competition, but they have shared predators such as raptors and snakes. Using playback experiments, we demonstrated that the iguana discriminates mobbing alarm calls of the flycatcher from its songs and then enhances its vigilance behaviour. Our results demonstrate the occurrence of an asymmetrical ecological relationship between the Madagascan spinytailed iguana and the paradise flycatcher through eavesdropping on information about the presence of predators. This implies that indirect interspecific interactions through information recognition may be more common than generally thought in an animal community.

A survey of lizards was conducted of Pantai Melawi, Bachok on 12-14 April and 11-13 May 2009. Nine species of lizards were recorded in this preliminary survey. They were from the family Agamidae (Calotes versicolor, Leiolepis belliana), family Gekkonidae (Cosymbotus platyurus, Gehyra mutilata, Gekko monarchus, Gekko gecko and Hemidactylus frenatus), family Scincidae (Eutropis multifasciata) and family Varanidae (Varanus salvator). The common species in this area were Leiolepis belliana and Hemidactylus frenatus. ABSTRAK
