Bioacoustic investigations and taxonomic considerations on the Cicadetta montana species complex (Homoptera: Cicadoidea: Tibicinidae)

Anais da Academia Brasileira de Ciências, 2004
Recent bioacoustic investigations have shown that Cicadetta montana Scopoli 1772 is a complex of morphologically similar sister species that are best characterized by their song patterns. At the type locality of C.

Innateness and the instinct to learn

Anais da Academia Brasileira de Ciências, 2004
Concepts of innateness were at the heart of Darwin's approach to behavior and central to the ethological theorizing of Lorenz and, at least to start with, of Tinbergen.

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 ...

Divergent echolocation call frequencies in insular rhinolophids (Chiroptera): a case of character displacement?

, 2007
Lo studio dimostra l'esistenza di fenomeni di divergenza bioacustica in popolazioni simpatriche insulari di chirotteri rinolofidi collegandoli a un possibile processo di character displacement generato dalla necessità di mantenere bande separate di ...

Rthoptera: Standardised insect bioacoustics in R

Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1084-1094, June 2025.
Abstract Almost 100 years after the dawn of insect bioacoustics, freely available and robust analysis tools and protocols are still needed. We introduce Rthoptera, an open‐source R package designed for robust analysis of insect acoustic signals. It delivers accurate temporal and spectral measurements, along with intuitive visualisations, through a ...

Caracterización de las señales acústicas de Lasiurus ega (Chiroptera: Vespertilionidae) en Santander, Colombia

Mammalogy Notes
Un desafío fundamental en la investigación bioacústica de murciélagos es la escasez de registros de referencia que documenten la variación intraespecífica de las señales emitidas, requisito esencial para una identificación confiable de especies.

Photo‐identification and satellite telemetry connect southern right whales from South Georgia Island (Islas Georgias del Sur) with multiple feeding and calving grounds in the southwest Atlantic

Marine Mammal Science, Volume 40, Issue 2, April 2024.
Abstract The sub‐Antarctic waters of South Georgia Island (Islas Georgias del Sur, SG/IG) are a regularly visited feeding ground for southern right whales (Eubalaena australis, SRW) in the southwest Atlantic. Satellite telemetry and photo‐identification records were compared to better understand the role of SG/IG in the SRW migratory network.
