evsBat: An automated toolkit for tracking and quantifying rapid movement of nocturnal animals using event cameras

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Capturing the high‐speed behaviour of nocturnal animals remains technically challenging because conventional video systems require intense illumination that disrupts natural activity. Event‐based vision sensors (EVS) overcome this constraint, yet their ecological uptake has been slow owing to a lack of software capable of analysing the sparse,

pyecoacc: A python package for supervised learning of behavioural modes from accelerometer data

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Supervised learning of behavioural modes from body‐worn sensor data, especially accelerometers, has become a transformative research tool in behavioural ecology over the past years. Due to the popularity of the methodology and diverging needs of users, there are a number of software packages dedicated to it, ranging from web based graphical ...

Regional movements of satellite‐tagged whale sharks Rhincodon typus in the Gulf of Aden

open access: yesEcology and Evolution, 2021
To gain insight into whale shark (Rhincodon typus) movement patterns in the Western Indian Ocean, we deployed eight pop‐up satellite tags at an aggregation site in the Arta Bay region of the Gulf of Tadjoura, Djibouti in the winter months of 2012, 2016 ...

Addressing Power Issues in Biologging: An Audio/Inertial Recorder Case Study

open access: yesSensors, 2022
In the past decades, biologging, i.e., the development and deployment of animal-borne loggers, has revolutionized ecology. Despite recent advances, power consumption and battery size however remain central issues and limiting factors, constraining the ...

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Behavioral Evidence of Predator–Predator Commensalism: Cobia Track and Feed on Prey Disturbed by Southern Stingrays

open access: yesEthology, Volume 132, Issue 3, Page 225-234, March 2026.
We documented a novel predator–predator commensal foraging interaction between cobia (Rachycentron canadum) and a southern stingray (Hypanus americanus) in a shallow coastal habitat of Biscayne Bay, Florida. Using drone‐based observations, we recorded a 7‐min sequence in which a cobia closely tracked the stingray's movements and fed on prey disturbed ...

Methods for detecting and quantifying individual specialisation in movement and foraging strategies of marine predators [PDF]

open access: yes, 2017
There is increasing realisation that individuals in many animal populations differ substantially in resource, space or habitat use. Differences that cannot be attributed to any a priori way of classifying individuals (i.e.

Why study cognition in the wild (and how to test it)? [PDF]

open access: yes, 2016
An animal's behavior is affected by its cognitive abilities, which are, in turn, a consequence of the environment in which an animal has evolved and developed.
