Implications of target signal choice in passive acoustic monitoring: an example of age‐ and sex‐dependent vocal repertoire use in African forest elephants (Loxodonta cyclotis)

Remote Sensing in Ecology and Conservation
Passive acoustic monitoring (PAM) is an effective remote sensing approach for sampling acoustically active animal species and is particularly useful for elusive, visually cryptic species inhabiting remote or inaccessible habitats.

Discrimination of Individual Tigers (\u3cem\u3ePanthera tigris\u3c/em\u3e) from Long Distance Roars [PDF]

, 2013
This paper investigates the extent of tiger (Panthera tigris) vocal individuality through both qualitative and quantitative approaches using long distance roars from six individual tigers at Omaha\u27s Henry Doorly Zoo in Omaha, NE.

Deciphering complex coral reef soundscapes with spatial audio and 360° video

Methods in Ecology and Evolution, EarlyView.
Abstract Coral reef soundscapes hold an untapped wealth of biodiversity information. While they are easy to record and filled with snapping shrimp and fish sounds, they are difficult to decipher because we know little about which sounds are made by which species. With identified fish sounds, acoustic monitoring can directly inform biodiversity metrics,

Amazonian manatee critical habitat revealed by artificial intelligence‐based passive acoustic techniques

Remote Sensing in Ecology and Conservation
For many species at risk, monitoring challenges related to low visual detectability and elusive behavior limit the use of traditional visual surveys to collect critical information, hindering the development of sound conservation strategies.

Male mice emit distinct ultrasonic vocalizations when the female leaves the social interaction arena. [PDF]

, 2013
Adult male mice emit large number of complex ultrasonic vocalizations (USVs) when interacting with adult females. Call numbers and call categories differ greatly among inbred mouse strains.

Current frontiers in the passive acoustic monitoring of bats

Methods in Ecology and Evolution, EarlyView.
Abstract Passive acoustic monitoring of bats is used in a growing number of studies in applied and basic research, from local to global scales. Despite the publication of good‐practice recommendations, several unsettled debates persist about the possibilities and limits offered by passive acoustic monitoring of bats.

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 ...

Sensors versus surveyors: Comparing passive acoustic monitoring, camera trapping and observer‐based monitoring for terrestrial mammals

Methods in Ecology and Evolution, EarlyView.
Abstract Mammals play vital roles in ecological communities, but many are in rapid decline worldwide. Comprehensive monitoring of mammal populations is crucial for effective conservation, but large‐scale monitoring presents significant challenges. Remote sensing techniques such as passive acoustic monitoring offer viable and effective solutions for ...

Influence of distance, frequency, habitat and angle of incidence on sound levels in passive acoustic monitoring with AudioMoth recorders

Annals of Applied Biology, EarlyView.
Sound levels of animal recordings are affected by their distance, direction, and the surrounding habitat. We estimated the magnitude of these effects for sound frequencies between 1.25 kHz (audible sound) and 50 kHz (ultrasound) using AudioMoth, a commonly used recorder in passive acoustic monitoring.

Complex taxonomy and global phylogeography of the well-known tropical earthworm Pontoscolex corethrurus [PDF]

, 2018
Few earthworm species are peregrine and among them, Pontoscolex corethrurus is the most well-known. Probably native from the Guyana shield, this earthworm is nowadays distributed worldwide, in the tropical and sub-tropical zones.
