Multi‐Platform Deployments of Low‐Cost Devices for Cetacean Passive Acoustic Monitoring

Remote Sensing in Ecology and Conservation, EarlyView.
Recent advances in affordable, user‐friendly devices offer new opportunities to overcome cost constraints of underwater passive acoustic monitoring (PAM) and expand acoustic data collection. In this study, we deployed low‐cost acoustic recorders and underwater cameras across a range of platforms in the Western Mediterranean, including fishing gear ...

Discovery and Fine‐Scale Mapping of Hadal Xenophyophore Habitat in the Nova Canton Trough, Central Pacific Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.

Improving Demographics and Conservation of Fishes Through Multi‐Frame Individual Distinctions by Size (MIDS)

Remote Sensing in Ecology and Conservation, EarlyView.
MIDS (Multi‐frame Individual Distinctions by Size) is a new software package for improving how fish populations are assessed using stereo‐video data. By using the length, error and statistical inference of measurements, MIDS distinguishes individuals across multiple video frames and autonomously removes repeat observations, regardless of when the ...

Repurposing Bird‐Based Acoustic Models for Amphibian Surveys: Strengths and Limitations in Real‐World Deployments

Remote Sensing in Ecology and Conservation, EarlyView.
In this study, we developed AnuraSearch, an open‐source classifier for 11 Ukrainian amphibian species, by repurposing the avian BirdNET algorithm via transfer learning to process over 18,000 h of autonomous acoustic recordings. Although the model demonstrated high precision and successfully reconstructed detailed seasonal and diel vocal activity ...
