Overlap and Segregation among Multiple 3D Home Ranges: A Non-Pairwise Metric with Demonstrative Application to the Lesser Kestrel Falco naumanni

Biology, 2023
In this study we solved the issue of measuring the degree of overlap/segregation among an arbitrarily large number (n ≥ 2) of 3D volumetric home ranges (i.e., x, y, and hg; where hg is height above ground level) for the first time.

State‐space models and inference approaches for aquatic animal tracking with passive acoustic telemetry and biologging sensors

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 418-434, February 2026.
Abstract Passive acoustic telemetry systems are widely deployed to track animals in aquatic environments. However, investments in integrative methods of data analysis have remained comparatively limited, with current workflows typically considering individual movements separately from space use, home ranges and residency.

Exfoliating Whales–Sandy Bottom Contact Behaviour of Humpback Whales

Journal of Marine Science and Engineering, 2023
Cetaceans are known for their intelligence and display of complex behaviours including object use. For example, bowhead whales (Balaena mysticetus) are known to rub on rocks and some humpback whale (Megaptera novaeangliae) populations undertake lateral ...

Global review of shorebird tracking data to identify research gaps and conservation priorities

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Tracking has enabled rapid advances in knowledge of the movement behavior and habitat use of shorebirds and is thus making a growing contribution to their conservation. However, realizing the full potential that tracking holds for conservation involves understanding what has been performed on shorebirds to date and identifying regional and ...

Environmental factors influencing red knot (Calidris canutus islandica) departure times of relocation flights within the non‐breeding period

Ecology and Evolution
Deciding when to depart on long‐distance, sometimes global, movements can be especially important for flying species. Adverse weather conditions can affect energetic flight costs and navigational ability.

The Life of Brian … and David: Two Flying‐Foxes' Contribution to Science

Ecology and Evolution, Volume 16, Issue 1, January 2026.
This Nature Note examines whether thumb bands and surgically implanted temperature transmitters adversely affect the welfare of free‐living grey‐headed flying‐foxes. Long‐term monitoring and necropsy findings from two males, Brian and David, suggest negligible impacts of these procedures on individual welfare. Although based on only two cases, the rare
