Ultrasonographic features of the platypus abdomen via a limited left pre‐epipubic acoustic window from a series of 54 individuals

Australian Veterinary Journal, EarlyView.
Introduction There are notable differences between the platypus and common species of domestic mammal in the location and structure of some abdominal organs. The aim of this study was to detail the size, position and relative locations of organs in the left side of the platypus abdomen, to assist evidence‐based decision‐making in a clinical setting ...

Emerging applications of large language models in ecology and conservation science

Conservation Biology, EarlyView.
Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

Northern cod (Gadus morhua) movement: insights from acoustic telemetry and genomics

Journal of Fish Biology, EarlyView.
Abstract Knowledge of the timing and diversity of fish movements within a commercially exploited stock complex is required to ensure the sustainability of fisheries. Although migration can be driven by environmental factors, genomic mechanisms also play an important role in this complex life‐history trait. The northern cod (Gadus morhua) stock complex,

The effects of playbacks of anthropogenic noise on the anti‐predator behaviour of Pacific sand lance, Ammodytes personatus

Journal of Fish Biology, EarlyView.
Abstract Noise from human activities has increased and been shown to negatively impact marine animals. Marine mammals and fish are vulnerable to anthropogenic noise because they rely on sound to communicate, find food, avoid predators and sense their environment. Forage fish are small schooling pelagic fish, important to many predators and instrumental

Social context shapes acoustic signalling in the territorial damselfish Stegastes fuscus

Journal of Fish Biology, EarlyView.
Abstract Acoustic communication plays an important role in social interactions in reef fishes, but how signals vary with behavioural context remains poorly understood for many species. We characterised the acoustic repertoire of the Brazilian damselfish Stegastes fuscus using synchronised underwater audio–video recordings and tested how sound features ...

Practical evaluation of differential frequency shift chirp modulation for acoustic underwater communication

, 2023
Frequency shift chirp modulation (FSCM) is a new modulation technique utilized by the LoRa physical layer. It is widely used in radio low-power wide area networks (LPWANs).
