Extreme moulting site fidelity of the Saimaa ringed seal
Site fidelity is commonly observed in pinnipeds and has direct consequences for individual space use and population dynamics. Here, we used photo-identification recapture data to quantify site fidelity of the endangered Saimaa ringed seal (Pusa hispida saimensis) over four successive moulting season...

Site fidelity is commonly observed in pinnipeds and has direct consequences for individual space use and population dynamics.
