Spatial and seasonal distribution of American whaling and whales in the age of sail. [PDF]
American whalemen sailed out of ports on the east coast of the United States and in California from the 18(th) to early 20(th) centuries, searching for whales throughout the world's oceans.

Killer Whales in the Central Tropical Pacific: Occurrence, Resightings, Morphology, and Acoustics
ABSTRACT Compared to their well‐studied coastal temperate counterparts, killer whales (Orcinus orca) in tropical‐subtropical and oceanic areas are under‐documented. We used sighting, photo‐identification, and acoustic data of killer whales in the central tropical Pacific (CTP), collected from multiple platforms between 2002 and 2023, to assess their ...

Adaptive Acoustic Monitoring for Endangered Cook Inlet Beluga Whales in Complex Soundscapes
ABSTRACT Effective conservation of the endangered Cook Inlet beluga whale (Delphinapterus leucas) requires comprehensive spatiotemporal data, yet monitoring efforts remain spatially biased, underrepresenting important southern habitats. Passive acoustic monitoring (PAM) provides the necessary broad‐scale coverage, but its expansion introduces ...

ABSTRACT Knowledge of mother–calf pairs, migratory patterns, female reproductive cycles, and birth‐year calf development are all essential for understanding risks in these critical life stages and monitoring little‐known dwarf minke whale (Balaenoptera acutorostrata) populations.

Early Post‐Release Movement Convergence in Reintroduced Giant Pandas
We used high‐frequency GPS tracking of eight reintroduced giant pandas (474 tracking days) to test how extreme energetic constraints shape movement during early post‐release adjustment. Principal component analysis of ten daily movement metrics revealed two independent movement axes (exploration–exploitation and tortuosity–consistency), and an ...

Variation in the Tyrosinase Gene Associated with a White Humpback Whale (Megaptera novaeangliae) [PDF]
Tyrosinase-negative oculocutaneous albinism (OCA1A) is characterized by lifelong white hair and skin, a phenotype that has been described in most mammalian species worldwide. Tyrosinase is the key enzyme in melanin biosynthesis, and mutations in the tyrosinase gene result in OCA1A.

More of the same: allopatric humpback whale populations share acoustic repertoire [PDF]
Background Humpback whales (Megaptera novaeangliae) are a widespread, vocal baleen whale best known for producing song, a complex, repetitive, geographically distinct acoustic signal sung by males, predominantly in a breeding context.

Influence of Solvent Lipid Extraction on Tissue‐Specific Carbon Isotopes
To assess the impact of solvents on δ13C, we used a standard lipid extraction protocol on four different pure proteins and humpback whale blubber, a very lipid‐rich tissue. The results showed that the solvents did not have a significant effect on δ13C and δ15N of pure proteins as values largely remained within 0.5‰ of unextracted samples, which is ...
