Pygmy Blue Whale Diving Behaviour Reflects Song Structure

Journal 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 ...

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

PLoS 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 ...

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.

Long‐Term Trends of Striped Bass Habitat Suitability Under a Temperature–Oxygen Squeeze in Lake Texoma, Oklahoma and Texas

Ecology and Evolution, Volume 16, Issue 6, June 2026.
This study examined the impact of summer temperature–oxygen squeezes on striped bass habitat, population size, and body condition in Lake Texoma from 1995 to 2020. Although suitable habitat volume consistently declined each summer, with temperature and oxygen influencing habitat in threshold‐dependent ways, we found no clear effects on striped bass ...

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.

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 ...

Season and human footprint weaken the negative effect of temperature on the intraspecific metabolic scaling exponent of wild brown trout populations

Journal of Animal Ecology, Volume 95, Issue 6, Page 989-1001, June 2026.
We apply a new parameterized model through linking metabolic scaling and the maximum entropy theory of ecology to quantify the intraspecific metabolic scaling exponent of brown trout populations and assess the main drivers shaping the exponent. Abstract Metabolic scaling fundamentally sets the pace of life in almost all organisms.

Biotelemetry

, 1988
Telemetric transmission of functional and physiological information offers many advantages in medical diagnostics and patient surveillance. The telemetric data link avoids direct connections to the recording or monitoring equipment, which are sometimes embarrassing and restraining, thus leaving the patients freely movable.

Uncovering temporal patterns of wildlife activity, habitat use and habitat preference from camera‐trap data

Methods in Ecology and Evolution, Volume 17, Issue 6, Page 1880-1895, June 2026.
Abstract An understanding of habitat use and levels of active behaviour is foundational to wildlife behaviour, ecology, conservation and management. These variables are commonly measured by tracking individuals in space and time using biologging. In principle, camera‐trap data also contain information about both activity level and habitat use; however,

Within‐Night Variation in Predictor Importance Highlights Dynamic Nature of Bird Migration

Ecology Letters, Volume 29, Issue 6, June 2026.
Bar chart summarising median percent of gain contributed by each predictor type (atmospheric, sampling and terrestrial) for each timestep after sunset for spring (left) and fall (right) bird migration seasons. Predictor types are denoted by different colours.
