Potencial de um método acústico em quantificar as atividades de bovinos em pastejo

Pesquisa Agropecuária Brasileira, 2011
O objetivo deste trabalho foi avaliar o potencial de um método acústico de quantificação do tempo de pastejo, de ruminação e de outras atividades realizadas por novilhas de corte em pastagem natural. Para obter registros sonoros, novilhas foram equipadas

Individual bird identification by modelling temporal structure in bioacoustic embeddings

Methods in Ecology and Evolution, Volume 17, Issue 10, Page 2909-2927, October 2026.
Abstract Identifying individual animals from vocalizations is an emerging research area in computational bioacoustics. This non‐invasive approach reduces reliance on physical capture and tagging for wildlife monitoring. Recent advances in this area leverage deep learning and bioacoustic foundation models adapted from species‐level classifiers. However,

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.

Soundscapes of the Upper Amazon: Seasonal Activity Patterns of Insectivorous Bats in Cordillera Escalera, Peru

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,
