Fishing Activity Affected Odontocete Cetacean Distribution in a Marine Protected Area in the East China Sea

Integrative Zoology, EarlyView.
Spatiotemporal distribution of odontocete cetaceans within China's Jiushan Archipelago National Nature Reserve was investigated. Fishing vessels significantly reduced both cetacean acoustic detections and feeding activity, whereas gillnets selectively suppressed cetacean feeding behavior without affecting overall cetacean detection rates.

Boat Noise Is Associated With Reduced Behavioral Lateralization in Juvenile Large Yellow Croaker (Larimichthys crocea)

Integrative Zoology, EarlyView.
Our results show that boat noise is associated with weaker expression of turning bias, poorer behavioral performance, elevated oxygen consumption, and concurrent gut‐associated shifts in juvenile Larimichthys crocea. These findings suggest that anthropogenic noise may influence not only physiological condition, but also behavioral phenotypes ...

Optimising the performance of acoustic telemetry receiver arrays for tracking aquatic animals using the arrayplanR package

Methods in Ecology and Evolution, EarlyView.
Abstract Strategically deploying acoustic telemetry receiver arrays is vital for tracking the movements of aquatic animals. Nevertheless, there is a lack of tools that provide the capacity to evaluate how well arrays perform in their study area, as well as ways to optimise receiver configurations to best meet study goals.

Downstream Passage Performance of European Silver Eels (Anguilla anguilla): The Importance of Phenotypic Variation and Rack Design

Animal Conservation, EarlyView.
During their spawning migration, European silver eels frequently encounter hydropower facilities where successful downstream passage is essential for the conservation of this critically endangered species. In this study, we evaluated how three angled rack designs and individual behavioral variation influenced downstream passage success in large‐scale ...

A Method for Underwater Acoustic Target Recognition Based on the Delay-Doppler Joint Feature

With the aim of solving the problem of identifying complex underwater acoustic targets using a single signal feature in the Time–Frequency (TF) feature, this paper designs a method that recognizes the underwater targets based on the Delay-Doppler joint ...

Movement Responses of Seals During Pile Driving for Offshore Wind Farm Construction

Animal Conservation, EarlyView.
Despite rapid growth of the renewable energy industry to meet climate change targets, predictions of population‐level impacts on wildlife are currently hindered by a limited understanding of individual behavioural responses to these developments.
