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 ...

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.
