The Beat Goes On: Humpback Whale Song Seasonality in Antarctic and South African Waters

Frontiers in Marine Science, 2022
Little is known of the movements and seasonal occurrence of humpback whales (Megaptera novaeangliae) of South Africa and the Antarctic, populations once brought to near extinction by historic commercial whaling.

Genetic tagging of humpback whales

Nature, 1997
The ability to recognize individual animals has substantially increased our knowledge of the biology and behaviour of many taxa. However, not all species lend themselves to this approach, either because of insufficient phenotypic variation or because tag attachment is not feasible.

Exploring the Use of Seabirds as a Dynamic Ocean Management Tool to Mitigate Anthropogenic Risk to Large Whales

Frontiers in Marine Science, 2022
Vessel strike and entanglement in fishing gear are global threats to large whales. United States management actions to reduce human-induced serious injury and mortality to large whales have been inadequate, partially due to static, spatial protection ...

Multi-year presence of humpback whales in the Atlantic sector of the Southern Ocean but not during El Niño

Communications Biology, 2021
Schall et al. use passive acoustic recordings of humpback whale calls to report the presence of humpback whales in the Atlantic sector of the Southern Ocean between 2011 and 2018. This serves as the first long-term report of humpback whales on a Southern

Foraging movements of humpback whales relate to the lateral and vertical distribution of capelin in the Barents Sea

Frontiers in Marine Science, 2023
Understanding how individual animals modulate their behaviour and movement patterns in response to environmental variability plays a central role in behavioural ecology.

Migratory destinations and spatial structuring of humpback whales (Megaptera novaeangliae) wintering off Nicaragua

Scientific Reports, 2023
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

Epigenetic estimation of age in humpback whales [PDF]

Molecular Ecology Resources, 2014
AbstractAge is a fundamental aspect of animal ecology, but is difficult to determine in many species. Humpback whales exemplify this as they have a lifespan comparable to humans, mature sexually as early as 4 years and have no reliable visual age indicators after their first year.

Distribution and abundance of large whales in Norwegian and adjacent waters based on ship surveys 1995-2001

NAMMCO Scientific Publications, 2009
The abundances of large whale species are presented for the northeast Atlantic from near-complete survey coverage in 1995 and from multiple partial-area surveys during 1996-2001.

Use of hormones in assessing reproductive physiology of humpback whales (Megaptera novaeangliae) from Juneau, Alaska

Theriogenology Wild, 2023
Humpback whales (Megaptera novaeangliae) in Southeast Alaska have been studied for over 50 years, and are largely considered a recovery success since the cessation of commercial whaling.
