For the 40 years after end of commercial whaling in 1976, humpback whale populations North Pacific Ocean exhibited a prolonged period recovery. Using mark–recapture methods on largest individual photo-identification dataset ever assembled for cetacean, we estimated annual ocean-basin-wide abundance species from 2002 through 2021. Trends estimates describe strong post-whaling era population recovery 16 875 (± 5955) to peak estimate 33 488 4455) 2012. An apparent 20% decline 2012 2021, 26 662...
We present an ocean-basin-scale dataset that includes tail fluke photographic identification (photo-ID) and encounter data for most living individual humpback whales (Megaptera novaeangliae) in the North Pacific Ocean. The was built through a broad collaboration combining 39 separate curated photo-ID catalogs, supplemented with community science data. Data from throughout were aggregated into 13 regions, including six breeding feeding one migratory corridor. All images compared minimal...
Abstract Humpback whales ( Megaptera novaeangliae ) are a cosmopolitan species and perform long annual migrations between low-latitude breeding areas high-latitude feeding areas. Their populations appear to be spatially genetically segregated due long-term, maternally inherited fidelity natal In the Southern Hemisphere, some humpback whale mix in Ocean waters summer, but very little movement Pacific Atlantic has been identified date, suggesting these constituted an oceanic boundary distinct...
Abstract The SPLASH project (2004–2006) revealed complex population structure and migratory connections, but no regional effort was made along the southern Mexican Pacific coast until dedicated research initiated in 2010. It is unclear whether humpback whales documented this region belong to or Central American units. This study aimed establish relationship between of Mexico those surrounding Humpback whale photo‐identification images were compared from multiple locations north, central,...
Abstract The cosmopolitan distribution of humpback whales ( Megaptera novaeangliae ) is largely driven by migrations between winter low-latitude breeding grounds and summer high-latitude feeding grounds. Southern Hemisphere faced intensive exploitation during the whaling eras recently show evidence population recovery. Gene flow shared song indicate overlap western (A) eastern (B1, B2) Breeding Stocks in South Atlantic Indian Oceans (C1). Here, we investigated photo-identification...
Abstract We present an ocean-basin-scale dataset that includes tail fluke photographic identification (photo-ID) and encounter data for the majority of living individual humpback whales ( Megaptera novaeangliae ) in North Pacific Ocean. The was built through a broad collaboration combining 39 separate curated photo-ID catalogs supplemented with community science data. All available images were compared using recently developed machine learning artificial intelligence image recognition...
