The use of bioacoustics in anuran taxonomy: theory, terminology, methods and recommendations for best practice.

open access: yesZootaxa, 2017
Vocalizations of anuran amphibians have received much attention in studies of behavioral ecology and physiology, but also provide informative characters for identifying and delimiting species.

A Generative AI‐Assisted Piezo‐MEMS Ultrasound Device for Plant Dehydration Monitoring

open access: yesAdvanced Science, EarlyView.
This study introduces a complementary metal–oxide–semiconductor (CMOS)‐compatible wearable piezoelectric micromachined ultrasound transducers (PMUTs) that sandwiches the leaf (PMUT–Leaf–PMUT, PLP) and employs generative artificial intelligence for real‐time analysis.

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

open access: yes, 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.

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

open access: yes, 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.

A systematic review evaluating the performance of eDNA methods relative to conventional methods for biodiversity monitoring

open access: yesEcography, EarlyView.
The rapid adoption of environmental DNA (eDNA) methods has drastically changed biodiversity monitoring efforts. It is often claimed that eDNA methods are more sensitive and efficient than conventional biodiversity monitoring methods, but it is often unclear what metrics support this claim.

Movement of Walleye in Lewis and Clark Lake Inferred From Acoustic Telemetry

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Walleye Sander vitreus is an economically important sport fish species with highly variable movement patterns, with individuals exhibiting site residency and others moving up to 350 km. Movement patterns of walleye are affected by both river regulation and shifting environmental conditions.

Bioacoustic differentiation of calls in the chiffchaff complex

open access: yesPeerJ, 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 ...
