Large‐Scale Forest Restoration Accompanied by Biodiversity Recovery in Costa Rica's Redistributive Payment for Ecosystem Service Program

Global Change Biology, Volume 32, Issue 2, February 2026.
Transforming recorded sound into meaningful ecological insights requires carefully designed methodologies. This workflow diagram describes the steps of our analysis (contained within circles labeled 1–7), which builds on best practices to correct for potential biases.

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

Annals of Applied Biology, Volume 188, Issue 1, Page 221-228, January 2026.
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.

Melon‐Headed Whale (Peponocephala electra) Occurrence in the Equatorial Mid‐Atlantic Ocean With Descriptions of Their Whistles

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Acoustic studies for any cetacean species in tropical Atlantic Ocean waters are scarce, especially for oceanic dolphins, such as the melon‐headed whale, Peponocephala electra. Here we describe a unique visual and acoustic record for this species, filling an information gap about the acoustic patterns of these delphinids in this part of the ...

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

Methods in Ecology and Evolution, Volume 16, Issue 11, Page 2603-2621, November 2025.
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 ...

Effective ecological monitoring using passive acoustic sensors: Recommendations for conservation practitioners

Conservation Science and Practice
Passive acoustic recorders have emerged as powerful tools for ecological monitoring. However, effective monitoring is not simply an act of recording sounds. To have meaning for conservation and management, acoustic monitoring needs to be properly planned
