Significance Human pressures are causing natural ecosystems to change at an unprecedented rate. Understanding these changes is important (e.g., inform policy decisions), but we hampered by the slow, labor-intensive nature of traditional ecological surveys. In this study, show that automated analysis sounds ecosystem—its soundscape—enables rapid and scalable monitoring. We used a neural network calculate fingerprints soundscapes from variety ecosystems. From acoustic could accurately predict...
Passive acoustic monitoring – an approach that utilizes autonomous recording units allows for non-invasive of individuals, assuming it is possible to acoustically distinguish individuals. However, identifying effective analytical approaches individual identification remains a challenge. Our study investigates how the use different feature representations impacts our ability between female Northern grey gibbons (Hylobates funereus). We broadcast pre-recorded calls from twelve gibbon females...
Abstract Passive acoustic monitoring (PAM) has the potential to greatly improve our ability monitor cryptic yet vocal animals. Advances in automated signal detection have increased scope of PAM, but distinguishing between individuals—which is necessary for density estimation—remains a major challenge. When individual identity known, supervised classification techniques can be used distinguish individuals. Supervised methods require labelled training data, whereas unsupervised do not. If...
Abstract Duetting, or the stereotypical, repeated and often coordinated vocalizations between 2 individuals arose independently multiple times in Order Primates. Across primate species, there exists substantial variation terms of timing, degree overlap, sex-specificity duet contributions. There is increasing evidence that primates can modify timing their contributions relative to partner, this vocal flexibility may have been an important precursor evolution human language. Here, we present...
Abstract Early morning calling occurs across diverse taxa, which may be related to optimal conditions for sound transmission. There exists substantial inter- and intra-specific variation in time is influenced by intrinsic, social and/or environmental factors. Here, we investigate predictors of gibbons. We hypothesized that male solos— occur earlier tend longer than duets—would more variables, if earlier, bouts are energetically costly, therefore limited overnight energy expenditure. Our top...
Passive acoustic monitoring (PAM) allows for the study of vocal animals on temporal and spatial scales difficult to achieve using only human observers. Recent improvements in recording technology, data storage, battery capacity have led increased use PAM. One main obstacles implementing wide-scale PAM programs is lack open-source that efficiently process terabytes sound recordings do not require large amounts training data. Here we describe a workflow detecting, classifying, visualizing...
Rapid urban development impacts the integrity of tropical ecosystems on broad spatiotemporal scales. However, sustained long-term monitoring poses significant challenges, particularly in regions. In this context, ecoacoustics emerges as a promising approach to address gap. Yet, harnessing insights from extensive acoustic datasets presents its own set such time and expertise needed label species information recordings. Here, study an investigating soundscapes: use deep neural network trained...
Vocal individuality has been documented in a variety of mammalian species and it proposed that this can be used as vocal fingerprint to monitor individuals. Here we provide test classification method using Mel-frequency cepstral coefficients (MFCCs) extract features from Bornean gibbon female calls. Our is semi-automated requires manual pre-processing identify calls the original recordings. We compared two methods MFCC feature extraction: (1) averaging across all time windows (2) creating...
Publishing preprints is quickly becoming commonplace in ecology and evolutionary biology. Preprints can facilitate the rapid sharing of scientific knowledge establishing precedence enabling feedback from research community before peer review. Yet, significant barriers to preprint use exist, including language barriers, a lack understanding about benefits diversity types outputs accepted (e.g. reports). Community-driven initiatives allow come together break down these improve equity coverage...
Evidence for compression, or minimization of code length, has been found across biological systems from genomes to human language and music. Two linguistic laws-Menzerath's Law (which states that longer sequences consist shorter constituents) Zipf's abbreviation (a negative relationship between signal length frequency use)-are predictions compression. It proposed compression is a universal in animal communication, but there have mixed results, particularly reference abbreviation. Like...
Effectively characterizing primate diets is fundamental to understanding behavior, ecology and morphology. Examining temporal variation in a species' diet, as well comparing the responses of different species resource availability, can enhance evolution morphology socioecology. In this study, we use feeding data collected over five years describe two sympatric Southeast Asian similar body size: white-bearded gibbons (Hylobates albibarbis) red leaf monkeys (Presbytis rubicunda rubida), Gunung...
Abstract Duets in pair-bonding primates serve as a primary mode of communication between pairs, and duets may provide cues to conspecifics regarding the calling individual or pair. Here, we test hypothesis that pulse elements coppery titi monkey vary with condition identity caller. We predicted would age, sex, pair-bond length. estimated rate duration for 378 from 74 captive monkeys ( Plecturocebus cupreus ). found inter-individual variation both features, evidence vocal convergence among...
As social animals, many primates use acoustic communication to maintain relationships. Vocal individuality has been documented in a diverse range of primate species and call types, which have presumably different functions. Auditory recognition one's neighbors may confer selective advantage if identifying conspecifics decreases the need participate costly territorial behaviors. Alternatively, vocal be nonadaptive result unique combination genetics environment. Pair-bonded primates,...
Great argus pheasants are known for their elaborate visual mating displays, but relatively little is about general ecology. The use of passive acoustic monitoring—which relies on long-term autonomous recorders—can provide insight into the behavior visually cryptic, yet vocal species such as great argus. Here we report results an analysis Bornean ( Argusianus grayi ) in Sabah, Malaysia, using data collected with 11 recording units. regularly emitted two call types, long and short call, found...
Abstract Understanding the ecological interactions between plant reproductive strategies and frugivore feeding behavior can offer insight into maintenance of tropical forest biodiversity. We examined role phenological characteristics in influencing fruit consumption by White‐bearded gibbon ( Hylobates albibarbis ) Gunung Palung National Park, Indonesian Borneo. Gibbons are widespread across Borneo, highly frugivorous perform important seed dispersal services. compare multiple models using...
Acoustic signals serve important functions in mate choice, resource defense, and species recognition. Quantifying patterns sources of variation acoustic can advance understanding the evolutionary processes that shape behavioral diversity more broadly. Animal vocalization datasets are inherently multivariate hierarchical, wherein multiple features estimated from calls many individuals across different recording locations. Patterns within hierarchical levels—notwithstanding challenges they...
Across diverse systems including language, music and genomes, there is a tendency for longer sequences to contain shorter constituents; this phenomenon known as Menzerath's Law. Whether Law universal in biological systems, the result of compression (wherein shortest possible strings represent maximum amount information) or emerges from an inevitable relationship between sequence constituent length remains topic debate. In non-human primates, vocalizations geladas, male gibbons chimpanzees...
Abstract Understanding niche partitioning of closely related sympatric species is a fundamental goal in ecology. Acoustic communication space can be considered resource, and the acoustic hypothesis posits that competition between may lead to space. Here, we compare calling behavior two Bornean hornbill species—the rhinoceros ( Buceros ) helmeted Rhinoplax vigil )—to test for evidence partitioning. Both emit calls heard over many kilometers have similar habitat preferences which predicted...
Passive acoustic monitoring (PAM) – an approach that uses autonomous recording units (ARUs) can provide insights into the behavior of cryptic or endangered species produce loud calls. However, extracting useful information from PAM data often requires substantial human effort, along with effective estimates detection range units, which be challenging to obtain. We studied duetting pair-living red titi monkeys ( Plecturocebus discolor ) using coupled open-source automated tool. Using on...
