Differences in the functional use of two migratory stopovers by humpback whales (Megaptera novaeangliae). [PDF]

open access: yesPLoS ONE
Humpback whale migration between tropical breeding grounds and polar feeding grounds is an energy-intensive activity undertaken on finite energy stores. The use of stopover sites to rest reduces energetic expenditure and provides enhanced opportunity for

The Hug of a Humpback Whale Mother: Protective Behaviors of a Calf Toward Escorts in a Competitive Group at Abrolhos Bank, Brazil [PDF]

open access: yesAnimals
While protective behaviors of baleen whales toward calves have been documented during predator attacks, they have not been observed in response to approach attempts by other males of the same species.

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

open access: yesProc 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.

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

open access: yesPLoS 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]

open access: yesJ 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]

open access: yesJASA 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

Back to Water: Signature of Adaptive Evolution in Cetacean Mitochondrial tRNAs [PDF]

open access: yes, 2016
The mitochondrion is the power plant of the eukaryotic cell, and tRNAs are the fundamental components of its translational machinery. In the present paper, the evolution of mitochondrial tRNAs was investigated in the Cetacea, a clade of Cetartiodactyla ...

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

open access: yesPeerJ, 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.
