Shifts in acoustic signature of Southern Hemisphere fin whales: Declining peak frequency of high-frequency components [PDF]

JASA Express Letters
Population-specific acoustic features are vital for using passive acoustic monitoring to study marine mammal populations in remote regions. Southern Hemisphere fin whale (Balaenoptera physalus) songs include region-specific high-frequency components ...

Estimating animal population density using passive acoustics [PDF]

, 2013
Reliable estimation of the size or density of wild animal populations is very important for effective wildlife management, conservation and ecology. Currently, the most widely used methods for obtaining such estimates involve either sighting animals from

Methods to measure biological sounds and assess their drivers in a tropical forest

MethodsX, 2022
The study of soundscapes and biological sounds is becoming the focus of increasing scientific attention. Studying biological sounds involves the deployment of acoustic sensors to record sounds and the identification of animal species and other sources of

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).

Assessing and correcting for the effects of species misclassification during passive acoustic surveys of cetaceans [PDF]

, 2013
In conservation ecology, abundance estimates are an important factor from which management decisions are based. Methods to estimate abundance of cetaceans from visual detections are largely developed, whereas parallel methods based on passive acoustic ...

Assessing the potential of autonomous submarine gliders for ecosystem monitoring across multiple trophic levels (plankton to cetaceans) and pollutants in shallow shelf seas [PDF]

, 2014
A combination of scientific, economic, technological and policy drivers is behind a recent upsurge in the use of marine autonomous systems (and accompanying miniaturized sensors) for environmental mapping and monitoring.
