Modelling movements of Saimaa ringed seals using anindividual-based approach
Movement is a fundamental element of animal behaviour, and it is the primary way through which ani-mals respond to environmental changes. Therefore, understanding the drivers of individual movementis essential for species conservation. The endangered Saimaa ringed seal (Phoca hispida saimensis) live...

Movement is a fundamental element of animal behaviour, and it is the primary way through which ani-mals respond to environmental changes. Therefore, understanding the drivers of individual movementis essential for species conservation.
