A 16‐Year Green Sturgeon Population Survey: Investigating River Discharge, Species Identification, Sampling Technology, Survey Extent and Possible Spawning Cyclic Dominance

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Monitoring and understanding the population structure of anadromous fishes is vital to their conservation. The southern distinct population segment of green sturgeon (Acipenser medirostris) is a threatened long‐lived anadromous fish, for which we have insufficient information about fundamental aspects of population structure.

The First Attempt of Satellite Tracking on Occurrence and Migration of Bryde’s Whale (Balaenoptera edeni) in the Beibu Gulf

open access: yesJournal of Marine Science and Engineering, 2021
Satellite-tagging is increasingly becoming a powerful biotelemetry approach to obtain remote measurement through tracking free-living cetaceans, which can fill knowledge gaps on cetaceans and facilitate conservation management.

Implementing Bayesian network models using expert elicitation for instream barrier assessment

open access: yesJournal of Applied Ecology, Volume 63, Issue 2, February 2026.
We have demonstrated that BN modelling and expert knowledge can be used for assessing the likelihood of fish passage where empirical data are lacking or sparse. The probabilistic framework is consistent with the need to reflect that many structures are partial barriers to fish movement and cannot be represented accurately in a binary pass/fail ...

First description of in situ chlorophyll fluorescence signal within East Antarctic coastal polynyas during fall and winter

open access: yesFrontiers in Marine Science, 2023
Antarctic coastal polynyas are persistent and recurrent regions of open water located between the coast and the drifting pack-ice. In spring, they are the first polar areas to be exposed to light, leading to the development of phytoplankton blooms ...

A review of acoustic telemetry in Europe and the need for a regional aquatic telemetry network [PDF]

open access: yes, 2018
Background Globally, there are a large and growing number of researchers using biotelemetry as a tool to study aquatic animals. In Europe, this community lacks a formal network structure.

Reviewing seas of data: Integrating image‐based bio‐logging and artificial intelligence to enhance marine conservation

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 2, Page 272-290, February 2026.
Abstract Conservation of marine ecosystems can be improved through a better understanding of ecosystem functioning, particularly the cryptic underwater behaviours and interactions of marine predators. Image‐based bio‐logging devices (including images, videos and active acoustic) are increasingly used to monitor wildlife movements, foraging behaviours ...

Simultaneous observation of intermittent locomotion of multiple fish by fine-scale spatiotemporal three-dimensional positioning. [PDF]

open access: yesPLoS ONE, 2018
Recent advances in biotelemetry techniques, especially positioning methods, have revealed the detailed behaviour and movement of aquatic organisms. Behavioural intermittence in animal locomotion, such as the Lévy walk, is a popular topic in the field of ...

Pygmy Blue Whale Diving Behaviour Reflects Song Structure

open access: yesJournal of Marine Science and Engineering, 2022
Passive acoustic monitoring is increasingly employed to monitor whales, their population size, habitat usage, and behaviour. However, in the case of the eastern Indian Ocean pygmy blue whale (EIOPB whale), its applicability is limited by our lack of ...

Animal geolocation with convolution algorithms in Julia and R via Wahoo.jl

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 2, Page 497-504, February 2026.
Abstract Animal geolocation is the core of movement ecology. In aquatic ecosystems, electronic tagging and tracking technologies, such as passive acoustic telemetry systems and biologging sensors, are widely deployed. However, statistical estimation of individual locations from these datasets can be challenging and computationally expensive.

Effect of Biologger Attachment on the Stress and Health State of the Spotted Sea Bass Lateolabrax maculatus

open access: yesJournal of Marine Science and Engineering
The biologger is a widely used tool in biotelemetry for investigating marine fish. However, studies reported that the attachment of biologgers has a negative effect on the target organisms.
