Species in subfamily Lipotactinae are brachypterous with a small body and have limited dispersal ability. In this study, it’s the first time to describe the male calling song of Lipotactes truncatus Shi & Li, 2009. MaxEnt was used to predict the potential geographic distribution of Lipotactinae in present-day and year 2070, to explore responses to global warming of this subfamily in China. As for L. truncatus, two types of calling songs are observed with peak frequencies in the ultrasound range. With the trend of global warming, the suitable habitats of subfamily Lipotactinae will change in three ways: i) migrate to high latitude area; ii) migrate to the coastal region of south China; iii) migrate along altitude gradients in mountains. Some species will be locked into the “sky islands”, which will accelerate speciation process, with global warming.

Human screams have been suggested to comprise a salient and readily identified call type, yet few studies have explored the degree to which people agree on what constitutes a scream, and the defining acoustic structure of screams has not been fully determined. In this study, participants listened to 75 human vocal sounds, representing both a broad acoustical range and array of emotional contexts, and classified each as to whether it was a scream or not. Participants showed substantial agreement on which sounds were considered screams, consistent with the idea of screams as a basic call type. Agreement on classifications was related to participant gender, emotion processing accuracy, and empathy. To characterize the acoustic structure of screams, we measured the stimuli on 27 acoustic parameters. Principal components analysis and generalized linear mixed modeling indicated that classification as a scream was positively correlated with 3 acoustic dimensions: one corresponding to high pitch and roughness, another corresponding to wide fundamental frequency variability and narrow interquartile range bandwidth, and a third positively correlated with peak frequency slope. Twenty-six stimuli were agreed upon by > 90% of participants to be screams, but these were not acoustically homogeneous, and others evoked mixed responses. These results suggest that while screams might represent a salient and possibly innate call type, they also exhibit perceptual and acoustic gradation, perhaps reflecting the wide range of emotions and contexts in which they occur.

Fish biomass estimation is one of the most common and important practices in aquaculture. The regular acquisition of fish biomass information has been identi- fied as an urgent need for managers to optimize daily feeding, control stocking densities and ultimately determine the optimal time for harvesting. However, it is difficult to estimate fish biomass without human intervention because fishes are sensitive and move freely in an environment where visibility, lighting and stability are uncontrollable. Until now, fish biomass estimation has been mostly based on manual sampling, which is usually invasive, time-consuming and laborious. Therefore, it is imperative and highly desirable to develop a noninvasive, rapid and cost-effective means. Machine vision, acoustics, environmental DNA and resistivity counter provide the possibility of developing nonintrusive, faster and cheaper methods for in situ estimation of fish biomass. This article summarizes the development of these nonintrusive methods for fish biomass estimation over the past three decades and presents their basic concepts and principles. The strengths and weaknesses of each method are analysed and future research direc- tions are also presented. Studies show that the applications of information tech- nology such as advanced sensors and communication technologies have great significance to accelerate the development of new means and techniques for more effective biomass estimation. However, the accuracy and intelligence still need to be improved to meet intensive aquaculture requirements. Through close coopera- tion between fisheries experts and engineers, the precision and the level of intelli- gence for fish biomass estimation will be further improved based on the above methods.

We describe a new species of Microhyla from Tram Lap forest, Gia Lai Province, Central Vietnam based on morpholog- ical, molecular, and acoustic data. The new species resembles M. butleri morphologically, but differs from all congeners by a combination of the following morphological attributes: (1) medium-sized adult snout–vent length 25.2–27.0 mm in 15 males and 30.5 mm in a single female; (2) body habitus moderately stocky; (3) head flat, snout rounded, slightly prom- inent in ventral profile; (4) dorsum and flanks slightly shagreened with evenly scattered tiny tubercles, ventral skin smooth; (5) first finger well developed, more than one-half the length of the second finger; (6) tips of three outer fingers slightly enlarged, forming weak disks and tips of all toes distinctly dilated into wide disks with narrow peripheral grooves; (7) finger and toe disks with dorsal median longitudinal grooves; (8) three palmar tubercles and two metatarsal tubercles; (9) tibiotarsal articulation of adpressed limb reaching slightly beyond the orbit; (10) webbing formula: I 13⁄4–2 II 11⁄2–23⁄4 III 2–31/3 IV 31⁄4–11⁄2 V; (11) in life, chin and throat yellowish to bright-orange with tiny dark brown speckling laterally; and (12) a call consisting of 15–26 pulses with a dominant frequency of 1.8–2.2 kHz (recorded at 18.5oC). We also provide a preliminary genealogy of Microhyla based on analysis of a 2644 bp fragment of 12S–16S rRNA mitochondrial DNA. Based on the examed data, the new species and M. butleri are sister-species (genetic p-distance: 9.0%) and it can be dis- tinguished from M. butleri by its morphology (size, webbing on toes, color) and advertisement call. Interspecific genetic p-distances between the new species and its congeners vary from 9.0% to 14.8%. Microhyla aurantiventris sp. nov. occurs in evergreen montane tropical forests at elevations around 1200 m a.s.l. and is known only from the type locality. The new species appears to be threatened due to intensive logging and agriculture plantation.

The acoustic channel is an efficient long-distance signalling system that may be especially effective for animals moving in the dark in a vast home range. The maned wolf’s extended-bark is a long-range vocalization that functions as a mechanism to increase spatial distance among conspecifics as well as to enable pair-mate reunion. Individual variations in this vocalization have been reported, but the possibility that they can be perceived and used by the species has never been tested. In our study, we used ABAB playback experiments to test if captive maned wolves could perceive individual variations. We ran 19 playback sessions with ten different subjects from six different zoos. After discarding nine sessions that did not fulfil minimal experimental conditions, in all except two of the ten valid trials, the subjects responded with displaying Oriented Attention. To our knowledge, this is the first demonstration that the maned wolf is capable of discriminating among extended-barks of different individuals.

This study examines the soundscape of minke whale habitat in the Scottish Inner Hebrides around the islands of Mull, Coll and Muck and near the Ardnamurchan Peninsula of the Scottish mainland. To compare the soundscape with minke whale presence and behavior, acoustic recordings were paired with behavior and respiration data. Acoustic recordings were taken using a Soundtrap 300, deployed from a whale watching vessel. Data was taken from June - September 2016. The soundscape was analyzed by comparing power spectral density averaged into octave bands (center frequencies from 16 Hz – 128 kHz). The soundscape of the region is ephemeral, with some locations having very different acoustic patterns depending on transient animal and human activity. Humans contribute to the soundscape through movement of small ships and dredging. Notable biological contributors to the soundscape include dolphins and snapping shrimp. Outside the island of Coll is quieter at mid-frequencies (2-8 kHz octave bands). Inside Coll is quieter at frequencies in the 16-128 kHz octave bands. Ardmore point, in the Sound of Mull, is louder for most frequencies. These differences create a potential way for animals to navigate or orient based on sound. Observed minke whale behaviors were categorized into behavior states to create a behavior budget. Minke whales in this area spend 56% of their daytime feeding, 7% traveling and 39% in other activities. The average inter-breath interval for minke whales in this study was 60.7s. Minke presence and behavior were compared with sound levels in 1/3rd octave bands using generalized linear models. Minke whale presence and behavior both correlate with changes in the Soundscape. Minke whales are less likely to be seen with higher levels of low (31 Hz) and high (25.4 kHz) frequency sound. Higher levels of sound at low (63 Hz) frequencies were associated with lower probability of minke whales feeding. Higher probability of minke whales feeding in higher levels of high (25.4 kHz) frequency sound may indicate that minke whales are optimizing that time which is spent in regions with higher levels of noise at these frequencies.

Insects have evolved a great diversity of sound-producing mechanisms largely attributable to their hardened exoskeleton, which can be rubbed, vibrated or tapped against different substrates to produce acoustic signals. However, sound production by forced air, while common in vertebrates, is poorly understood in insects. We report on a caterpillar that ‘vocalizes’ by forcing air into and out of its gut. When disturbed, larvae of the Nessus sphinx hawkmoth (Sphingidae: Amphion floridensis) produce sound trains comprising a stereotyped pattern of long (370 ms) followed by multiple short-duration (23 ms) units. Sounds are emitted from the oral cavity, as confirmed by close-up videos and comparing sound amplitudes at different body regions. Numerical models using measurements of the caterpillar foregut were constructed to test hypotheses explaining sound production. We propose that sound is generated by ring vortices created as air flows through the orifice between two foregut chambers (crop and oesophagus), a mechanism analogous to a whistling kettle. As air flows past the orifice, certain sound frequencies are amplified by a Helmholtz resonator effect of the oesophagus chamber. Long sound units occur during inflation, while short sound units occur during deflation. Several other insects have been reported to produce sounds by forced air, but the aeroacoustic mechanisms of such sounds remain elusive. Our results provide evidence for this mechanism by showing that caterpillars employ mechanisms similar to rocket engines to produce sounds.

In animal communication, signal loudness is often ignored and seldom measured. We used a playback experiment to examine the role of vocal loudness (i.e., sound pressure level) in sibling to sibling communication of nestling barn owls Tyto alba. In this species, siblings vocally negotiate among each other for priority access to parental food resources. Call rate and call duration play key roles in this vocal communication system, with the most vocal nestlings deterring their siblings from competing for access to the food item next delivered by parents. Here, we broadcast calls at different loudness levels and call rate to live nestlings. The loudness of playback calls did not affect owlets' investment in call rate, call duration or call loudness. The rate at which playback calls were broadcast affected owlets' call rate but did not influence their response in terms of loudness. This suggests that selection for producing loud signals may be weak in this species, as loud calls may attract predators. Moreover, given that owlets do not overlap their calls and that they communicate to nearby siblings in the silence of the night, loud signals may not be necessary to convey reliable information about food need.

We introduce a novel approach to studying animal behavior and the context in which it occurs, through the use of microphone backpacks carried on the backs of individual free-flying birds. These sensors are increasingly used by animal behavior researchers to study individual vocalizations of freely behaving animals, even in the field. However, such devices may record more than an animal's vocal behavior, and have the potential to be used for investigating specific activities (movement) and context (background) within which vocalizations occur. To facilitate this approach, we investigate the automatic annotation of such recordings through two different sound scene analysis paradigms: A scene-classification method using feature learning, and an event-detection method using probabilistic latent component analysis. We analyze recordings made with Eurasian jackdaws (Corvus monedula) in both captive and field settings. Results are comparable with the state of the art in sound scene analysis; we find that the current recognition quality level enables scalable automatic annotation of audio logger data, given partial annotation, but also find that individual differences between animals and/or their backpacks limit the generalization from one individual to another. we consider the interrelation of “scenes” and “events” in this particular task, and issues of temporal resolution.

Passive acoustic monitoring of dolphins is limited by our ability to classify calls to species. Significant overlap in call characteristics among many species, combined with a wide range of call types and acoustic behavior, makes classification of calls to species challenging. Here, we introduce BANTER, a compound acoustic classification method for dolphins that utilizes information from all call types produced by dolphins rather than a single call type, as has been typical for acoustic classifiers. Output from the passive acoustic monitoring software, PAMGuard, was used to create independent classifiers for whistles, echolocation clicks, and burst pulses, which were then merged into a final, compound classifier for each species. Classifiers for five species found in the California Current ecosystem were trained and tested using 153 single-species acoustic events recorded during a 4.5 mo combined visual and acoustic shipboard cetacean survey off the west coast of the United States. Correct classification scores for individual species ranged from 71% to 92%, with an overall correct classification score of 84% for all five species. The conceptual framework of this approach easily lends itself to other species and study areas as well as to noncetacean taxa.

For most insects, size determines the call frequency. This paper describes the acoustics of a small brachypterous cricket (Rufocephalus sp.; body length 9.6 mm) producing a call with a carrier frequency of approximately 3.2 kHz from a subterranean burrow. Crickets such as Gryllus campestris are approximately twice this length and produce a call frequency close to 5 kHz. The burrow of Rufocephalus opens via a small hole with a diameter of 3.2 mm. The neck of the hole at approximately 1.4 mm depth opens to a vertical two-part burrow with an upper vase-shaped chamber 16.1 mm in height with a diameter of 9.4 mm. This top chamber connects via a 6.4mm high (diameter 5.2 mm) neck to a more irregular chamber approximately 18 mm high with a width of approximately 11 mm. The walls of the top chamber neck and of the upper part of the lower chamber are smooth and appear to be sealed with saliva. The song has a mean centre frequency of 3.2 kHz and is made up of variable-length trills of pulses of mean duration 15.8 ms. Many song pulses had smooth envelopes and their frequency did not vary by more than +/-40Hz from the centre frequency, with a relative bandwidth Q-3dB of over 50. Other pulses showed considerable amplitude and frequency modulation within the pulse. When driven by external sound, burrows resonated at a mean frequency of 3.5 kHz with a mean quality factor Q of 7.4. Natural-size model burrows resonated at similar frequencies with similar Q values. One cricket, which had previously called from its own burrow at 2.95 kHz, sang at 3.27 kHz from a burrow that resonated at the same frequency. Life-size model burrows driven by external sound resonated at similar frequencies to the actual burrows; models three times life size resonated at one-third of this frequency. In all models, the sound pressure was more-or-less constant throughout the top chamber but fell rapidly in the neck of the burrow; the phase of the sound was effectively constant in the top chamber and neck and fell through approximately 180 degrees in passing from the neck into the lower chamber. A numerical model of the sound flow from region to region gave essentially similar results. A resonant electrical model fed from a high-impedance source with discrete tone bursts at different frequencies showed similar amplitude and frequency modulation to the various types of song pulses that were observed. It is suggested that the high purity of the songs results from close entrainment of the sound-producing mechanism of the insect's wings to the sharply resonant burrow.

Recordings were compared of the male calling songs and analysis performed of selected acoustic variables. This analysis is combined with sequencing of mtDNA - COI and examination of morphological traits to perform cluster analyses. The trees constructed from different datasets were structurally similar, bisecting the six geographical populations studied. Based on two large branches in the analysis, the species Gampsocleis sedakovii was partitioned into two subspecies, Gampsocleis sedakovii sedakovii (Fischer von Waldheim, 1846) and Gampsocleis sedakovii obscura (Walker, 1869). Comparing all the traits, the individual of Elunchun (ELC) was the intermediate type in this species according to the acoustic, genetic, and morphological characteristics. This study provides evidence for insect acoustic signal divergence and the process of subspeciation.10aacoustics10agene10ainterim morphs10amorphology10asubspecies1 aZhang, Xue1 aWen, Ming1 aLi, Junjiain1 aZhu, Hui1 aWang, Yinliang1 aRen, Bing-Zhong uhttp://zookeys.pensoft.net/articles.php?id=604302436nas a2200217 4500008004100000022001400041245010700055210006900162260001600231300001200247490000700259520175500266653001402021653001202035653001202047653001602059653001102075653001702086100002402103856009102127 2007 eng d a1082-646700aSound generation in Mantis religiosa (Mantodea: Mantidae): stridulatory structures and acoustic signal0 aSound generation in Mantis religiosa Mantodea Mantidae stridulat cJan-06-2007 a35 - 490 v163 a

Several species of mantids perform defensive displays during close-range encounters with predators. In adult Mantis religiosa, this display entails both visual and acoustic components, the latter being abdominoalary stridulation. Stridulatory modifications of the abdomen and hindwings and acoustic properties of the defensive sounds of M. religiosa are characterized here for the first time. Defensive sounds are generated via an abdominoalary mechanism involving contact between teeth found on the longitudinal veins of the metathoracic wings and pegs located on the abdominal pleura. Defensive stridulation in M. religiosa is highly variable in both spectral and time domains. Inter-individual variability may be stochastically greater than intra-individual variability for at least one acoustic parameter (peak frequency). The loudest portion of a sound emission (syllable), or down-pulse, has an average duration of 195 ms and features an abrupt rise to maximum amplitude. Inter-syllabic intervals are irregular and rate of syllable production depends on a mantid's sex. The acoustic output of M. religiosa is nonresonant, broadband, and of relatively low intensity. A minor ultrasonic component may be present in the spectra of these mantids (particularly in males). The modal peak frequency range (4 kHz interval) is 8-12 kHz (mean range ∼7.4-9.4 kHz). Acoustic parameters which appear to vary between the sexes and/or among females at different reproductive stages, may be related to the sexual size dimorphism of this species and morphological constraints associated with egg-bearing. The acoustic output of M. religiosa is considered with reference to its intended receivers and plausible mechanisms of predator deterrence.

Females of Panoploscelis specularis present a dramatic modification of their forewings for stridulation. The female generator is illustrated and its distinct form contrasted with that of males. The physical form of the signals that females might produce is inferred; male calling and protest signals are characterized. The male of P. specularis is described for the first time.

The Chorthippus biguttulus group includes a number of common European species that are difficult to distinguish morphologically but are easily recognized in the field by the distinctive calling songs of the males. These song-patterns have not previously been studied in Spain and as a result the Iberian members of the group have been misidentified in almost all the extensive Spanish literature on the ecology and cytogenetics of these insects. In this study the male calling songs of all six members of the group known from the Iberian Peninsula and North Africa are fully described and illustrated with oscillograms at several different speeds. The songs of the three species known only from Iberia or North Africa, jacobsi, yersini and marocanus, are fully described for the first time (marocanus is here raised in rank from subspecies). Notes on recognition, using both morphology and song, are given for each species, and two identification keys are provided, one based on morphology and the other on song. It is shown that the three species biguttulus, brunneus and mollis, previously believed to be widespread in Iberia, are absent from most of the peninsula.
