Animal tracking is the practice of monitoring and studying animal movements and behaviour in their natural environment from a distance, across various spatial and temporal scales, through a suit of tools and technologies.
Thanks to this methodology, researchers are able to gather key information about the biology and ecology of organisms, providing insights for conservation frameworks and regulations. In addition, the analysis covers extended temporal periods, regardless of weather conditions, with minimal environmental and individual disturbance.
A practical example is the landmark study co-authored by LifeWatch Belgium’s researchers Pieterjan Verhelst and Jan Reubens (who is also coordinating LifeWatch ERIC’s Thematic Service Working Group on Animal Tracking). The study brings together tracking data from 18 previous studies involving more than 2300 exemplars of nature’s great traveller: the European eel (Anguilla anguilla), with the objective of gathering insights on its migration, and the environmental barriers that hinder it.
The eels travels up to 9,000 km from continental Europe and northern Africa to spawn in the Atlantic Ocean, although it is yet unclear to scientists how they coordinate their migration across such vast distances.
Through acoustic telemetry and the Nedap Trail System, and collaboration between LifeWatch Belgium and the European Tracking Network (ETN), the researchers came to reveal some striking patterns in the duration of the migration, as well as differences in speed according to the type of habitat (tidal VS non-tidal).
They could also confirm how substantial obstacles such as pumping stations, or hydropower plants, affect the migration by delaying its course. Read the whole article on LifeWatch Belgium to learn more: https://www.lifewatch.be/news/europe-atlantic-new-insights-eel-migration.
