Passive Acoustic Monitoring Reveals New Insights Into the Acoustic Occurrence and Foraging Activity of Hector's Dolphins in Porpoise Bay, New Zealand

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
To effectively mitigate disturbances from human activities on vulnerable dolphin populations, it is crucial to understand fine‐scale variation in habitat use. This study investigated the habitat utilisation of a small subpopulation of Hector's dolphins (Cephalorhynchus hectori) in Porpoise Bay, New Zealand.

Tracking Cairns: Biologging Improves the Use of Seabirds as Sentinels of the Sea

open access: yesFrontiers in Marine Science, 2017
In 1987, David Cairns proposed that a gradient of colony-based measures on seabirds could be used to assess food supply in the ocean. Measures closely tied to the ocean, such as foraging trip duration, would be sensitive to small declines in food supply ...

Detecting disease progression from animal movement using hidden Markov models

open access: yesJournal of Applied Ecology, Volume 63, Issue 3, March 2026.
We demonstrate how (H)HMMs can be tailored to different epidemiological scenarios and provide a template workflow for developing and selecting Hidden Markov models to infer disease status from animal movement data. Identifying infection before mortality occurs offers a valuable early‐warning tool for population managers, reduces reliance on difficult ...

animal2vec and MeerKAT: A self‐supervised transformer for rare‐event raw audio input and a large‐scale reference dataset for bioacoustics

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 3, Page 875-888, March 2026.
Abstract Bioacoustic research, vital for promoting conservation and understanding animal behaviour and ecology, faces a monumental challenge: analysing vast datasets where animal vocalizations are rare. While deep learning techniques are becoming standard, adapting them to bioacoustics remains difficult.

Foraging movements of Audouin’s gull (Larus audouinii) in the Ebro Delta, NW Mediterranean: A preliminary satellite-tracking study [PDF]

open access: yes, 2012
5 pages, 3 figures, 1 tableA knowledge of the foraging strategies of marine predators is essential to understand the intrinsic factors controlling their distribution, abundance and their ecological function within the marine ecosystem.

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

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 3, Page 903-913, March 2026.
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,

Evaluating satellite‐transmitter backpack‐harness effects on greater sage‐grouse survival and device retention in the Great Basin

open access: yesWildlife Society Bulletin
Wildlife tracking studies have become ubiquitous in ecology and now provide previously unobtainable data regarding individual movement, vital rates, and population demographics. However, tracking devices can potentially reduce survival of study subjects,

Tracking the kinematics of caudal-oscillatory swimming : a comparison of two on-animal sensing methods [PDF]

open access: yes, 2016
Funding: Marie Sklodowska Curie Career Integration Grant and by The Marine Alliance for Science and Technology for Scotland (MASTS).Studies of locomotion kinematics require high-resolution information about body movements and the specific acceleration ...
