Vertical Habitat Use by Japanese Jack Mackerel Trachurus japonicus Inferred From a Biologging Study in Tokyo Bay

Fisheries Oceanography, Volume 35, Issue 4, Page 518-531, July 2026.
ABSTRACT The movement ecology of Trachurus japonicus in the adult stage remains poorly understood because observing their underwater behavior over long periods is challenging. This study aimed to examine vertical habitat use by T. japonicus using electronic tags. Ninety fish were tagged and released in November 2022 in Tokyo Bay, Japan.

Weather Effects on the Haul‐Out Behaviour of Ringed Seals in the Amundsen Gulf

Marine Ecology, Volume 47, Issue 4, July/August 2026.
ABSTRACT Ringed seals (Pusa hispida) use sea ice year‐round in the Arctic as a platform for giving birth, raising young and moulting. Arctic ringed seal population assessments are typically conducted by aerial surveys flown in the spring, when many seals haul out. However, many factors can influence whether a seal is hauled out on the ice and available

Revealing migration and reproductive habitat of invasive fish under an active population suppression program

Conservation Science and Practice, 2020
Endemic species face a variety of threats including predation from non‐native invaders. In some cases, however, invasive species can be managed by directly suppressing populations, and tracking technologies that allow researchers to identify movement ...

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 ...

In-Vivo Implantable Sensor System for Measuring Bladder Wall Movements

Proceedings, 2017
The design and implementation of a medical implantable device for bladder monitoring is presented. A network of accelerometers is to be implanted in-between the outside bladder muscle and the mucous membrane.

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.

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.

Plugging biologging into animal welfare: An opportunity for advancing wild animal welfare science

Methods in Ecology and Evolution
Animal welfare science is currently expanding beyond its traditional boundaries, from captive animals to those living in the wild. This current development is conceptually and methodologically challenging, but it could benefit from adjacent and more ...

Intercolony and Intra‐Annual Variations in Isotopic Niche of Red‐Footed Boobies Sula sula in the Tropical Indian Ocean

Ecological Research, Volume 41, Issue 3, May 2026.
We compared the diet and assessed geographic and seasonal variations in the isotopic niches of red‐footed boobies across three Indian Ocean atolls. Our results demonstrate plasticity in both diet and trophic niche, likely driven by local environmental conditions, breeding stages, and colony‐specific factors.
