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

open access: yesEcological 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.

Acoustic telemetry reveals high site fidelity of yellow‐phase American eels Anguilla rostrata in a large river

open access: yesJournal of Fish Biology, Volume 108, Issue 5, Page 1444-1461, May 2026.
Abstract Movement patterns and habitat use of yellow‐phase American eels Anguilla rostrata in the Wolastoq/Saint John River were examined using acoustic telemetry. Tracking 72 tagged yellow‐phase eels from late summer 2021 to autumn 2023 revealed overall restricted longitudinal movements (mean linear range ± standard deviation [SD] 6.4 ± 10.9 km) and ...

Why catch when you can throw? A framework for tagging animals without capture or restraint

open access: yesRoyal Society Open Science
The use of electronic tags has significantly advanced our understanding of wild animal behaviour and physiology. However, traditional tagging methods often require capturing and restraining or sedating animals, which causes stress and may potentially ...

Fish movements before, during, and after restoration of tidal flow through culverts in two southern Florida USA mangrove creeks

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
In this study, we implanted transmitters into fishes to track their movements while culverts were installed and creeks were excavated to restore a mangrove forest. Results suggest that fish were not displaced during the restoration and they did not readily utilize the restored creeks once they were completed.

Efeitos cardiovasculares da anestesia dissociativa na reposição volêmica com colóide e solução hipertônica em cães: avaliação biotelemétrica Cardiovascular effects of dissociative anesthesia in the volemic expansion with colloid and hypertonic solution in dogs: biotelemetric evaluation

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2009
Avaliaram-se os efeitos cardiovasculares por um período de 24 horas, após a administração de solução salina hipertônica (NaCl) 7,5% ou em associação ao hidroxietilamido 130/0,4 (HES), em cães com hipovolemia induzida e tratados com cetamina levógira ou ...

Territorial birds of prey adjust their flight behaviour over the course of the breeding season depending on their breeding success

open access: yesJournal of Avian Biology, Volume 2026, Issue 2, March 2026.
Flight plays a central role in the life histories of birds but is extremely energy demanding. Reproduction is also associated with high energy demands. We might thus expect to see differences in movement behaviour between individuals that breed successfully, those that breed unsuccessfully, and those that do not breed, assuming that individuals adapt ...

A Conceptual Framework and Methods for Studying the Connectivity of Fishes

open access: yesFish and Fisheries, Volume 27, Issue 2, Page 342-369, March 2026.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

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

open access: yesMethods 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 ...
