Vulnerability of tropical fish communities across depth in the central Indian Ocean

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Coral reefs and their fish communities below scuba diving depth (>30 m), in mesophotic coral ecosystems (MCEs) (∼30–150 m), in rariphotic (150–300 m), and in upper bathyal waters (300–500 m) are often underexplored, especially in the Indian Ocean.

A Proposed Method for Assessing the Spatio-Temporal Distribution of Carcharhinus melanopterus (Quoy and Gaimard, 1824) in Shallow Waters Using a UAV: A Study Conducted in Koh Tao, Thailand

open access: yesDiversity
In this study, we propose a method for assessing the temporal and spatial distribution of Carcharhinus melanopterus in shallow waters using unmanned aerial vehicles (UAVs).

DNA Divers: Volunteer‐based eDNA capture for local and global marine biodiversity monitoring

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2431-2447, October 2025.
Abstract Volunteer‐based biodiversity recording is a powerful source of scalable data yet to be used to its full potential by the scientific community. Coastal ecosystems are varied and diverse, making it difficult for managers to identify flexible methods for monitoring biological components.

Zero‐shot shark tracking and biometrics from aerial imagery

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 9, Page 2023-2035, September 2025.
Abstract The recent widespread adoption of drones for studying marine animals provides opportunities for deriving biological information from aerial imagery. The large scale of imagery data acquired from drones is well suited for machine learning (ML) analysis.

Speed‐dependent locomotor patterns during steady swimming in a demersal shark

open access: yesJournal of Fish Biology, Volume 107, Issue 2, Page 394-405, August 2025.
Abstract Swimming ability is critical for navigating complex benthic habitats, yet the biomechanical strategies demersal sharks employ to modulate body and fin movements across varying speeds remain largely unexplored. This study examines speed‐dependent kinematic patterns in the small‐spotted catshark (Scyliorhinus canicula), a benthic species with ...

Using citizen science photographs to identify reproductive events in an oviparous elasmobranch

open access: yesJournal of Fish Biology, Volume 107, Issue 2, Page 419-430, August 2025.
Abstract Identifying critical habitats is important for the effective management of vulnerable species. Critical habitats, such as mating or nursery grounds, support populations during key life stages and help to maximise reproductive output and population growth. In elasmobranchs, mating often happens over a defined season, suggesting sites associated
