Listening to tropical forest soils

Ecological Indicators
Acoustic monitoring has proven to be an effective tool for monitoring biotic soundscapes in the marine, terrestrial, and aquatic realms. Recently it has been suggested that it could also be an effective method for monitoring soil soundscapes, but has ...

PNW-Cnet v4: Automated species identification for passive acoustic monitoring

SoftwareX, 2023
We present PNW-Cnet v4, a deep neural net with an associated Shiny-based application designed to facilitate efficient data processing to detect terrestrial wildlife species through passive acoustic monitoring.

Open‐source workflow approaches to passive acoustic monitoring of bats

Methods in Ecology and Evolution, 2023
AbstractThe affordability, storage and power capacity of compact modern recording hardware have evolved passive acoustic monitoring (PAM) of animals and soundscapes into a non‐invasive, cost‐effective tool for research and ecological management particularly useful for bats and toothed whales that orient and forage using ultrasonic echolocation. The use

Passive acoustic monitoring and automated detection of the American bullfrog

Biological Invasions
AbstractBiological invasions pose significant threats to biodiversity and ecosystem functioning. Removal of introduced species is most successful when detected early. We evaluate the effectiveness of passive acoustics combined with automated recognition in detecting the invasive American bullfrog (Lithobates catesbeianus).

Calls of North Atlantic right whales Eubalaena glacialis contain information on individual identity and age class

Endangered Species Research, 2016
Passive acoustic monitoring is a powerful tool that allows remote detection of marine mammals through their vocalizations. While call detection provides information on species presence, additional information may be contained within the vocalizations ...

In the still of the night: revisiting Eastern Whip-poor-will surveys with passive acoustic monitoring

Avian Conservation and Ecology, 2022
Recent advances in passive acoustic monitoring warrant the review of survey protocols because passive acoustic monitoring can increase sampling effort with minimal additional cost.

Passive acoustic monitoring paired with machine learning outperforms playback surveys for a rare and cryptic species, the Black‐billed Cuckoo (Coccyzus erythropthalmus)

Conservation Science and Practice
Monitoring rare and cryptic species presents unique challenges and is of high importance for conservation practitioners. In this study, we evaluate the use of in‐person playback surveys and passive acoustic monitoring for a rare and cryptic avian species,

Transfer Learning for Distance Classification of Marine Vessels Using Underwater Sound

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Marine environments are increasingly affected by human activities, which generate underwater noise as a by-product. Acoustic data from these environments can offer valuable insights for tracking human activity and improving the monitoring of sensitive ...

Clicking throughout the year: sperm whale clicks in relation to environmental conditions off the west coast of South Africa

Endangered Species Research, 2020
Knowledge of cetacean occurrence and behaviour in southern African waters is limited, and passive acoustic monitoring has the potential to address this gap efficiently. Seasonal acoustic occurrence and diel-vocalizing patterns of sperm whales in relation

Active and Passive Acoustic Methods for In-situ Monitoring of the Ocean Status [PDF]

, 2017
Recent European strategic plans for the successful monitoring of the status of the ocean push on the development of an integrated observing system able to further link existing instruments and techniques with the aim to complement each other and answer open issues.
