Global diversity and oceanic divergence of humpback whales (Megaptera novaeangliae). [PDF]

Proc Biol Sci, 2014
Humpback whales (Megaptera novaeangliae) annually undertake the longest migrations between seasonal feeding and breeding grounds of any mammal. Despite this dispersal potential, discontinuous seasonal distributions and migratory patterns suggest that humpbacks form discrete regional populations within each ocean.

Microplastic in a macro filter feeder: Humpback whale Megaptera novaeangliae

Marine Pollution Bulletin, 2015
Marine filter feeders are exposed to microplastic because of their selection of small particles as food source. Baleen whales feed by filtering small particles from large water volumes. Macroplastic was found in baleen whales before. This study is the first to show the presence of microplastic in intestines of a baleen whale (Megaptera novaeangliae ...

Hemisphere-Level Comparison of Climate-Driven Humpback Whale Breeding Migrations to the Eastern Pacific Off Costa Rica. [PDF]

Ecol Evol
This study analyzed humpback whale occurrence off the Pacific coast of Costa Rica from 2001 to 2023, focusing on the Central America and Southeast Pacific Distinct Population Segments, using long‐term sightings and Bayesian time‐series and habitat models.

Passive acoustic tracking of singing humpback whales (Megaptera novaeangliae) on a northwest Atlantic feeding ground. [PDF]

PLoS ONE, 2013
Passive acoustic tracking provides an unobtrusive method of studying the movement of sound-producing animals in the marine environment where traditional tracking methods may be costly or infeasible.

Multivariate analysis of behavioural response experiments in humpback whales (Megaptera novaeangliae). [PDF]

J Exp Biol, 2013
Summary The behavioural response study (BRS) is an experimental design used by field biologists to determine the function and /or behavioural effects of conspecific, heterospecific or anthropogenic stimuli. When carrying out these studies in marine mammals it is difficult to make basic observations and achieve sufficient samples sizes ...

Fuzzy clustering as a tool to differentiate between discrete and graded call types [PDF]

JASA Express Letters, 2021
Animals may communicate potential information to conspecifics using stereotyped “discrete” calls and variable “graded” calls. However, animal vocal research often centers on identifying the number of call types in a repertoire rather than quantifying the

Norrisanima miocaena, a new generic name and redescription of a stem balaenopteroid mysticete (Mammalia, Cetacea) from the Miocene of California [PDF]

PeerJ, 2019
Rorqual whales are among the most species rich group of baleen whales (or mysticetes) alive today, yet the monophyly of the traditional grouping (i.e., Balaenopteridae) remains unclear.

Humpback Whale (Megaptera novaeangliae) Song on a Subarctic Feeding Ground

Frontiers in Marine Science, 2021
Male humpback whales (Megaptera novaeangliae) are known to produce long complex sequences of structured vocalizations called song. Singing behavior has traditionally been associated with low latitude breeding grounds but is increasingly reported outside ...
