For the 40 years after the end of commercial whaling in 1976, humpback whale populations in the North Pacific Ocean exhibited a prolonged period of recovery. Using mark–recapture methods on the largest individual photo-identification dataset ever assembled for a cetacean, we estimated annual ocean-basin-wide abundance for the species from 2002 thro...

Humpback whales Megaptera novaeangliae undertake extensive annual migrations, have complex migratory patterns, and have held several mammalian long-distance movement records. Here, we report on a whale known to feed in the Russian Far East that was sighted in breeding areas on either side of the North Pacific, the Mariana Islands and Mexico, in les...

Understanding the migratory patterns of large whales is of conservation importance, especially in identifying threats to specific populations. Migration ecology, including migratory destinations, movements and site fidelity for humpback whales (Megaptera novaeangliae) remain poorly studied in parts of the range of the Central America population, co...

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 dataset was built through a broad collaboration combining 39 separate curated photo-ID catalogs, supplemented with community sc...

Current knowledge of the abundance, movements, and population structure of humpback whales (Megaptera novaeangliae) at the scale of the entire North Pacific Ocean is based primarily on data collected during and prior to 2004-06. In recent years, new technology and international collaboration among research groups across the North Pacific have enabl...

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 was initiated in 2010. It is unclear whether humpback whales documented in this region belong to the Mexican or Central American population units. This stud...

The Winter aggregation of humpback whales off the southern coasts of Baja California peninsula constitute both a destination and transit area for these whales during their migratory cycle (Urbán et al., 2000). There are whales in transit from the mainland coasts and from the Revillagigedo Archipelago This is the aggregation with a higher turnover r...

Amyloid-β (Aβ) plays a relevant role in the neurodegenerative process of Alzheimer's disease (AD). The 25-35 peptide of amyloid-β (Aβ25-35) induces the inflammatory response in brain experimental models. Mucin-type O-glycosylation has been associated with inflammation of brain tissues in AD, thus in this work, we aimed at identifying changes in the...

Baleen whale vocal activity can be the dominant underwater ambient noise source for certain locations and seasons. Previous wind-driven ambient-noise formulations have been adjusted to model ambient noise levels generated by random distributions of singing humpback whales in ocean waveguides and have been combined to a single model. This theoretica...

Previous research has investigated whether diffuse ambient noise levels can be used to estimate relative baleen whale abundance in environments where their vocal activity dominates ambient noise levels. Presented here is an analytical model of ambient noise levels as generated by randomly distributed singing humpback whales. The model exploits earl...
