Abstract Mate choice plays a pivotal role in wildlife reproduction and population sustainability. The assessment of sexual displays noise poses common challenge for wildlife. Multimodal signals are hypothesized to be favored since they improve the accuracy signal detection discrimination noise. We verified whether female treefrogs exhibit heightened reliance on visual cues when acoustic drowned out by noise, increased call complexity can compensate attractiveness differences between unimodal...
Most species are believed to evolve larger body sizes over evolutionary time. Previous studies have suggested that sexual selection, through male-male competition and female choice, favors males. However, there is little evidence of selection against large size. The serrate-legged small treefrogs (Philautus odontotarsus) must carry passive males from leks breeding grounds relatively long distances after amplexus find a suitable place lay eggs. costs male size may therefore decrease mating...
Abstract The matched filter hypothesis proposes that the tuning of auditory sensitivity and spectral character calls will match in order to maximize processing efficiency during courtship. In this study, we analyzed acoustic structure male both female hearing sensitivities little torrent frog ( Amolops torrentis ), an anuran species who transmits signals across streams. results were striking contradiction hypothesis. Auditory brainstem response showed best range was 1.6–2 kHz consistent with...
Abstract Many kinds of environmental noise can interfere with acoustic communication and efficient decision making in terrestrial species. Here we identified an exception to this generalization a streamside species, the little torrent frog ( Amolops torrentis ) which communicates stream environment. To determine whether act as cue regarding microhabitat characteristics senders, performed phonotaxis experiments using stimulus pairs constructed synthetic male calls (high or low dominant...
Anesthesia is known to affect the auditory brainstem response (ABR) in mice, rats, birds and lizards. The present study investigated how level of anesthesia affects ABR recordings an amphibian species, Babina daunchina. To do this, we compared ABRs evoked by tone pip stimuli recorded from 35 frogs when Tricaine methane sulphonate (MS-222) anesthetic immersion times varied 0, 5 10 minutes after induction at sound frequencies between 0.5 6 kHz. thresholds increased significantly with time...
The evolution of exaggerated vocal signals in anuran species is an important topic. Males and females have both evolved the ability to discriminate communication sounds. However, nature sexual dimorphism cognition sensory discrimination limitation signal exaggeration remain relatively unexplored.In present study, we used male calls varied complexity serrate-legged small treefrog, Kurixalus odontotarsus, as probes investigate how sexes respond variations call sex differences play a role...
A hallmark of sexual selection by mate choice is the evolution exaggerated traits, such as longer tails in birds and more acoustic components calls frogs. Trait elaboration can be opposed costs increased metabolism greater predation risk, but cognitive processes receiver also put a brake on trait elaboration. For example, according to Weber's Law traits fixed absolute difference will difficult discriminate magnitude increases. Here, we show that Emei music frog (Babina daunchina) increases...
It is generally thought that for species using vocal communication the spectral properties of sender's calls should match frequency sensitivity receiver's auditory system. Nevertheless, few studies have investigated both sender and receiver characteristics in anuran species. In present study, brainstem responses (ABRs) were recorded serrate legged treefrog, Philautus odontotarsus, order to determine if male call structure hearing males females co-evolved this The results showed structures...
There is increasing evidence that many anurans use multimodal cues to detect, discriminate and/or locate conspecifics and thus modify their behaviors. To date, however, most studies have focused on the roles of in female choice or male-male interactions. In present study, we conducted an experiment investigate whether male serrate-legged small treefrogs (Kurixalus odontotarsus) used visual chemical detect females altered competition strategies different calling contexts. Three acoustic...
Abstract Animal choruses, such as those found in insects and frogs, are often intermittent. Thus, females sampling males the chorus might have to remember location of potential mates' calls during periods silence. Although a number studies shown that frogs use prefer multimodal mating signals, usually acoustic plus visual, it is not clear why they do so. Here we tested hypothesis preference for signals over unimodal be due instantiating longer memories than particularly inter‐chorus...
Male-male vocal competition in anuran species is critical for mating success; however, it also energetically demanding and highly time-consuming. Thus, we hypothesized that males may change signal elaboration response to real time. Male serrate-legged small treefrogs (Kurixalus odontotarsus) produce compound calls contain two kinds of notes, harmonic sounds called A notes short broadband B notes. Using male evoked experiments, found influences the temporal structure complexity signals...
Abstract Background Signal detection is crucial to survival and successful reproduction, animals often modify behavioral decisions based on information they obtained from the social context. Undeniably, decision-making in male-male competition female choice of anurans (frogs toads) depends heavily acoustic signals. However, increasing empirical evidence suggests that additional or alternative types cue (e.g., visual, chemical, vibratory) can be used detect, discriminate locate conspecifics...
The matched filter hypothesis proposes that the auditory sensitivity of receivers should match spectral energy distribution senders' signals. If so, be able to distinguish between species-specific and hetero-specific We tested in two sympatric species, Chiromantis doriae Feihyla vittata, whose calls exhibit similar frequency characters overlap breeding season microenvironment. For both we recorded male measured sexes using brainstem response (ABR). compared with each species found (1) signal...
Both human and nonhuman animals communicating acoustically face the problem of noise interference, especially anurans during mating activities. Previous studies concentrated on effect continuous signal recognition, but it is still unknown whether different notes in advertisement calls impaired by affect female choice male-male competition or not. In this study, we tested preferences male-evoked vocal responses serrate-legged small tree frog (
Variation in signal complexity is common among different species. Understanding why some species have evolved extensive call can offer insight into the evolution of complex signals. In this study, we investigated functions types a treefrog using network analysis, male playback experiments, and correlation analysis between properties body size. Our results show that treefrogs produce three kinds notes be combined to single-note as well composite calls. We also identified an intermediate note...
Abstract Communication signals by both human and non-human animals are often interrupted in nature. One advantage of multimodal cues is to maintain the salience signals. We studied a frog that naturally can have silent gaps within its call. Using video/audio-playbacks, we presented females with mating calls or without simultaneous dynamic (i.e., inflating deflating) vocal sac tested whether multisensory (noise and/or sac) inserted into gap compensate an found neither inserting white noise...
Temperature is a critical factor in shaping the physiological and metabolic processes of animals, notably impacting their auditory systems. Particularly, ectotherms face heightened vulnerability to temperature fluctuations. To comprehend impact rapid changes on sensitivity ectotherms, we measured Xenopus laevis at 10°C, 20°C, 30°C respectively, using brainstem response. Our results reveal significant decrease X. with thresholds markedly higher than those observed 20°C 30°C. Conversely, as...
Animal coloration offers a unique opportunity to explore the evolutionary mechanisms underlying phenotypic diversity. Conspicuous caused by pigments plays crucial role in social signaling across multiple species conveying information about individual quality, ranks, or reproductive condition. Nevertheless, most previous studies have focused predominantly on colors produced exogenous pigments—carotenoids. Pterins are another prevalent group of conspicuous pigments, which can be endogenously...
Abstract Disruption of cochlear architecture and development can lead to malfunction, resulting in hearing defects. However, the spatial molecular profiles critical for function remain poorly understood due structural complexity cochlea. In this study, we performed comprehensive spatiotemporal transcriptomic analyses on developing adult cochlea, identifying numerous genes with gradient expression patterns hair cells (HCs) spiral ganglion neurons (SGNs) across apical-to-basal axis. The gene...
Mammals suffer permanent hearing impairment from the loss of auditory hair cells due to their inability regenerate. In contrast, lower vertebrates exhibit extraordinary capacity for cell regeneration and restoration, but mechanisms remain unclear. Here we characterize single-cell atlas Xenopus laevis inner ear perform a comprehensive comparison with mouse model. An exceptionally conserved neuronal type is discovered. The results reveal that outer (OHCs) exist exclusively in mammals....
Abstract Human disturbance, particularly road traffic, is one of the greatest threats to wildlife. Considering association between alerting behavior and survival animals, it important study effects traffic on Previous studies assessing short-term impact wildlife have focused vigilance distances. However, use alarm calls are scarce, unclear whether such behavioral responses change after repeated exposure traffic. We assessed plateau pikas (Ochotona curzoniae) who were near or far from roads...
