Kogia Records in Brazilian Equatorial and Southwestern Atlantic Oceans
Marine Mammal Science, Volume 42, Issue 4, October 2026.ABSTRACT The pygmy (Kogia breviceps) and dwarf (Kogia sima) sperm whales are cryptic cetaceans characterized by inconspicuous surfacing behavior, small group sizes, and deep‐diving habits, making visual detection particularly challenging. Here, we present the first broad‐scale passive acoustic monitoring (PAM) assessment of Kogia spp.

Biotropica, Volume 58, Issue 5, September 2026.ABSTRACT Bats, the second most diverse group of mammals, play essential ecological roles in insect control, pollination, and seed dispersal. In Peru, insectivorous bats remain poorly studied, particularly in high‐elevation rainforest ecosystems of the upper Amazon region.

Bioacoustic Baselines for Intact Forests
Global Change Biology, Volume 32, Issue 5, May 2026.The Soundscape Baselines Project is a global initiative to collect and analyse bioacoustic baselines in the world's remaining intact forests. The baseline data are collected using a modular system of passive acoustic monitoring and ancillary data that can be expanded and integrated with other technologies.

The Development of SONAR as a Tool in Marine Biological Research in the Twentieth Century
International Journal of Oceanography, Volume 2013, Issue 1, 2013., 2013 The development of acoustic methods for measuring depths and ranges in the ocean environment began in the second decade of the twentieth century. The two world wars and the “Cold War” produced three eras of rapid technological development in the field of acoustic oceanography. By the mid‐1920s, researchers had identified echoes from fish, Gadus morhua,

Optimization of passive acoustic bird surveys: a global assessment of BirdNET settings
Ibis, Volume 168, Issue 2, Page 785-798, April 2026.BirdNET is a popular machine learning tool for automated recognition of bird sounds. However, evidence on how to optimize its settings for accurate bird monitoring remains limited. Here, we evaluate how BirdNET settings influence model performance in identifying bird vocalizations and characterizing bird communities, using 4224 1‐min recordings from 67

A computational framework to characterize and compare the tonal repertoires of toothed whales
Methods in Ecology and Evolution, Volume 16, Issue 7, Page 1350-1368, July 2025.Abstract Toothed whales, despite being one of the most acoustically specialized lineages of vertebrates, lack detailed vocal repertoire characterizations comparable to those of songbirds and primates. Current descriptions often lack standardization, limiting interspecies and intraspecies comparisons critical for understanding the contribution of ...
