Tagging through the stages: technical and ecological challenges in observing life histories through biologging [PDF]

, 2012
Biologging data have provided important insights into the biology of marine mammals, sea turtles, birds, fish, and some invertebrates. These techniques have primarily targeted adult organisms.

Novel insights into sex-specific differences in heart rate variability and autonomic nervous system regulation during spawning behavior in chum salmon (Oncorhynchus keta) revealed by re-analysis of ECG logger data

Frontiers in Physiology
This study reanalysed electrocardiogram (ECG) data collected in a previous study on chum salmon to explore sex-specific differences in heart rate variability (HRV) and autonomic nervous system regulation during spawning.

Too Few, Too Many, or Just Right? Optimizing Sample Sizes for Population‐Level Inferences in Animal Tracking Projects

Ecology and Evolution, Volume 16, Issue 6, June 2026.
We present a flexible workflow to determine optimal sample sizes in animal tracking studies, balancing sampling duration, interval, and number of tagged individuals. Integrated into an R package and Shiny application, it supports rigorous and cost‐effective study design to improve inferences and inform conservation, while considering logistical and ...

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,

Multi-Sensor Assessment of Pigeon Flight Behavior: Role of Biomechanical and Landscape Characteristics

Sensors
Understanding how birds adjust their flight in response to biomechanical characteristics and environmental conditions can be useful for interpreting homing behavior.

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.

Annual survival rates of satellite-tracked adult European honey buzzards (Pernis apivorus) based on the Kaplan-Meier estimator and its probabilistic extension

Raptor Journal
The annual survival rate of adult raptors is an important parameter in population dynamics and is needed to derive measures for population stability and conservation management. Here we studied adult European honey buzzards (Pernis apivorus), a migratory

Beyond Bergmann and Allen: A Unified Framework for Thermoregulatory Morphology

Global Ecology and Biogeography, Volume 35, Issue 6, June 2026.
ABSTRACT Context Ecogeographical rules such as Bergmann's and Allen's have long guided expectations about how organismal size and shape vary across temperature gradients. Yet these rules are typically tested independently despite sharing a common thermoregulatory basis.
