Site fidelity and residence times of humpback whales ( Megaptera novaeangliae) on the Brazilian coast
Humpback whales ( Megaptera novaeangliae ) migrate between their feeding grounds, located in high latitudes, and their breeding grounds, located in low latitudes, exhibiting certain levels of site fidelity to their migratory destinations. The residence time, also known as occupancy rate, can be defi...
