Development of a non-invasive heart rate measurement method for sea turtles with dense keratinous scutes through effective electrode placement

Frontiers in Physiology
Measuring the heart rate of sea turtles is important for understanding their physiological adaptations to the environment. Non-invasive methods to measure the electrocardiogram (ECG) of sea turtles have been developed by attaching electrodes to their ...

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.

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

Satellite tracking of tiger sharks in the Eastern Central Atlantic reveals varied space-use patterns and ocean-basin connectivity

Frontiers in Marine Science
Large-bodied sharks, including the tiger shark (Galeocerdo cuvier), play crucial roles as top predators in marine ecosystems, regulating lower trophic-level populations and connecting ecosystems across vast distances. However, elasmobranchs, particularly

State‐space models and inference approaches for aquatic animal tracking with passive acoustic telemetry and biologging sensors

Methods in Ecology and Evolution
Passive acoustic telemetry systems are widely deployed to track animals in aquatic environments. However, investments in integrative methods of data analysis have remained comparatively limited, with current workflows typically considering individual ...

The icing of external recorders during the polar winter [PDF]

, 2004
Recorders and transmitters are commonly attached to suitable polar species of vertebrates. When using these devices, power and memory are two of the most limiting factors in successful experiments.
