Humpback and Fin Whaling in the Gulf of Maine from 1800 to 1918 [PDF]

, 2002
The history of whaling in the Gulf of Maine was reviewed primarily to estimate removals of humpback whales, Megaptera novaeangliae, especially during the 19th century.

Source levels of social sounds in migrating humpback whales (Megaptera novaeangliae) [PDF]

, 2013
The source level of an animal sound is important in communication, since it affects the distance over which the sound is audible. Several measurements of source levels of whale sounds have been reported, but the accuracy of many is limited because the ...

Unveiling Patterns in Cetacean Strandings Along Southern Atlantic Iberia: Temporal and Spatial Trends, Seasonality, and Causes of Death

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT We compiled 46 years of cetacean strandings in the Algarve, Portugal, describing temporal–spatial patterns, size–sex structure, and causes of death (COD). We analyzed national records and years with a dedicated regional stranding network (SN) to assess annual/seasonal trends, spatial hotspots, and compare biometrics and COD.

Humpback Whale (Megaptera novaeangliae) Intra/Inter-Seasonal Exchanges Between Puerto Rico and the Southeastern Caribbean

Animal Behavior and Cognition, 2019
A study of humpback whales (Megaptera novaeangliae, Borowski, 1781) was conducted off Puerto Rico, from 2012 through 2016, in an attempt to understand the spatial and temporal connection among current low density areas throughout the southeastern ...

Information theory analysis of Australian humpback whale song [PDF]

, 2008
Songs produced by migrating whales were recorded off the coast of Queensland, Australia, over six consecutive weeks in 2003. Forty-eight independent song sessions were analyzed using information theory techniques.

Singing humpback whales Megaptera novaeangliae favor specific frequency bands [PDF]

Proceedings of Meetings on Acoustics, 2018
Many species alter their acoustic signals in response to environmental or anthropogenic factors. Differential use of frequency bands may occur as a result of overlapping biotic and abiotic sounds that interfere with communication signals between conspecifics.

Correcting Lipid Extraction Effects on Nitrogen Isotopic Values (δ15N) in Cetacean Skin

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Stable isotopes of carbon (δ13C) and nitrogen (δ15N) are widely used to study the feeding ecology of cetaceans, as they provide critical insights into diet and migratory behaviors. Lipids in tissues may bias the interpretation of δ13C. Because of this, lipids need to be extracted before measuring stable isotope ratios, but their removal may ...

Humpback whales interfering when mammal-eating killer whales attack other species: mobbing behavior and interspecific altruism? [PDF]

, 2016
Humpback whales (Megaptera novaeangliae) are known to interfere with attacking killer whales (Orcinus orca). To investigate why, we reviewed accounts of 115 interactions between them. Humpbacks initiated the majority of interactions (57% vs.

Population Demographics of Killer Whales (Orcinus orca) in Western Australia

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Understanding population demographics is crucial for the effective conservation of species. This is particularly important for apex predators, such as the killer whale (Orcinus orca), which play important roles in maintaining the structure and function of ecosystems. In this study, we used capture‐mark‐recapture (CMR) modeling to assess killer

Humpback whales off Peru: new records and a rationale for renewed research. Scientific Committee document SC/48/SH1, International Whaling Commission, June 1986, Aberdeen [PDF]

, 1996
New records indicate that some Area I humpback whales are present in coastal upwelling waters off Peru and Chile during the austral summer, and thus apparently fail to migrate to the Antarctic.
