ORCA-SPOT: An Automatic Killer Whale Sound Detection Toolkit Using Deep Learning [PDF]

, 2019
Large bioacoustic archives of wild animals are an important source to identify reappearing communication patterns, which can then be related to recurring behavioral patterns to advance the current understanding of intra-specific communication of non ...

Vocal complexity in the long calls of Bornean orangutans [PDF]

PeerJ
Vocal complexity is central to many evolutionary hypotheses about animal communication. Yet, quantifying and comparing complexity remains a challenge, particularly when vocal types are highly graded.

Marine mammal acoustic detections in the Greenland and Barents Sea, 2013 – 2014 seasons [PDF]

, 2018
While the Greenland and Barents Seas are known habitats for several cetacean and pinniped species there is a lack of long-term monitoring data in this rapidly changing environment.

Automatic Classification and Speaker Identification of African Elephant (\u3cem\u3eLoxodonta africana\u3c/em\u3e) Vocalizations [PDF]

, 2005
A hidden Markov model (HMM) system is presented for automatically classifying African elephant vocalizations. The development of the system is motivated by successful models from human speech analysis and recognition.

Ultrasonic Vocalization Acoustics After Recurrent Laryngeal Nerve Injury and Recovery

The Laryngoscope, EarlyView.
Reliable and functional biomarkers in animal models of recurrent laryngeal nerve (RLN) injury are needed to ensure translation of treatments from the laboratory to the clinic. This study aimed to investigate the impact of RLN injury on rodent ultrasonic vocalization (USV) acoustics in both acute and chronic stages of injury.

Birds, bats and beyond: evaluating generalization in bioacoustics models

Frontiers in Bird Science
In the context of passive acoustic monitoring (PAM) better models are needed to reliably gain insights from large amounts of raw, unlabeled data. Bioacoustics foundation models, which are general-purpose, adaptable models that can be used for a wide ...

Low Survivals and Rapid Demographic Decline of a Threatened Estuarine Delphinid

Frontiers in Marine Science, 2022
Beibu Gulf’s (BBG) Indo-Pacific humpback dolphins present both a genetic differentiation and phenotypical differences from conspecifics from other areas of the South China Sea.

Resolving abrupt frontal gradients in zooplankton community composition and marine snow fields with an autonomous Zooglider

Limnology and Oceanography, EarlyView.
Abstract An autonomous Zooglider navigated across the California Current Front into low salinity, minty waters characteristic of the California Current proper in both summers of 2019 and 2021. Diving to 400 m depth, Zooglider transited another near‐surface frontal gradient somewhat inshore. These frontal gradients were generally associated with changes

Bioacoustic differentiation of calls in the chiffchaff complex

PeerJ, 2022
The chiffchaff complex is a group of common forest bird species, notorious for the number of cryptic taxa recently discovered, being a great example of speciation in action. Vocalizations have been crucial to unveil its hidden diversity. In this study we quantitatively analyze the acoustic characteristics of their calls with permutational analysis of ...
