Quantifying permeability of linear barriers to animal movement: The permeability R package

Methods in Ecology and Evolution, Volume 17, Issue 7, Page 2039-2051, July 2026.
Abstract Animals have always navigated environments characterized by linear features that influence movement, whether rivers, ridges or ravines. Large‐scale changes in land use have led to increasing interactions with anthropogenic features, especially roads and fences.

Penguins on the Move: Mapping Priority Penguin Habitat Areas Under Climate Change

Diversity and Distributions, Volume 32, Issue 7, July 2026.
ABSTRACT Aim To identify and map Priority Penguin Habitat Areas (PPHAs), defined as marine regions that are environmentally suitable for penguins under present and future climates, in order to inform climate‐smart conservation planning across Southern Hemisphere. Location Marine realms of the Southern Hemisphere. Methods We modelled occurrence data for

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

Journal 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.

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.

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

Frontiers 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 ...

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

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

Journal 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.

Investigation on Insulated, Brain-Implanted Antenna for Highly Reliable Biotelemetry Communication in MICS and ISM Bands

Sensors, 2019
We derived a closed-form expression of the maximum power transfer efficiency (MPTE) between a transmitting antenna inside the brain and a receiving antenna outside the head using spherical wave expansion. The derived expression was validated using a FEKO
