Effectiveness of acoustic indices as indicators of vertebrate biodiversity

Ecological Indicators, 2023
Effective monitoring tools are key for tracking biodiversity loss and informing management intervention strategies. Passive acoustic monitoring promises to provide a cheap and effective way to monitor biodiversity across large spatial and temporal scales,

Acoustically assessing apes: chimpanzee conservation with passive acoustic monitoring [PDF]

, 2022
With one million species at risk of extinction, there is an urgent need to regularly monitor threatened wildlife. In practice this is challenging, especially with wide-ranging, elusive and cryptic species or those that occur at low densities, such as chimpanzees (Pan troglodytes).

Estimating bird density using passive acoustic monitoring: a review of methods and suggestions for further research

Ibis, 2021
Passive acoustic monitoring is a non-invasive tool for automated wildlife monitoring. This technique has several advantages and addresses many of the biases related to traditional fi eld surveys.

Long-Term Passive Acoustic Monitoring to Support Adaptive Management in a Sciaenid Fishery (Tagus Estuary, Portugal)

Reviews in Fish Biology and Fisheries, 2023
Passive acoustic monitoring (PAM) is useful for monitoring vocal fish but has had so far limited application in fisheries management. Here, four years (2016–2019) of concurrent daily catch and effort fishery data in Portugal and species-specific vocal ...

Large‐scale long‐term passive‐acoustic monitoring reveals spatio‐temporal activity patterns of boreal bats

Ecography, 2023
The distribution ranges and spatio-temporal patterns in the occurrence and activity of boreal bats are yet largely unknown due to their cryptic lifestyle and lack of suitable and efficient study methods.

Sperm whale presence observed using passive acoustic monitoring from gliders of opportunity

Endangered Species Research, 2020
Habitat use by the endangered Mediterranean sperm whale subpopulation remains poorly understood, especially in winter. The sustained presence of oceanographic autonomous underwater vehicles in the area presents an opportunity to improve observation ...
