Feeding Hotspots and Distribution of Fin and Humpback Whales in the Norwegian Sea From 2013 to 2018

Frontiers in Marine Science, 2021
Fin whales (Balaenoptera physalus) and humpback whales (Megaptera novaeangliae) are commonly found in the Norwegian Sea during the summer months. Records from around 1995 to 2004 show that their distribution patterns were mainly associated with those of ...

Solitary humpback whales manufacture bubble-nets as tools to increase prey intake. [PDF]

R Soc Open Sci
Several animal species use tools for foraging; however, very few manufacture and/or modify those tools. Humpback whales, which manufacture bubble-net tools while foraging, are among these rare species.

Tidal effects on periodical variations in the occurrence of singing humpback whales in coastal waters of Chichijima Island, Ogasawara, Japan. [PDF]

Sci Rep, 2022
Marine organisms inhabiting coastal waters are known to be driven by periodic cycles such as diel, tidal, and seasonal changes. Humpback whales (Megaptera novaeangliae) breed in shallow and warm coastal waters, with males singing complex songs during the

Detection of humpback whale (Megaptera novaeangliae) non-song vocalizations around the Vema Seamount, southeast Atlantic Ocean [PDF]

JASA Express Letters, 2022
Humpback whales are a cosmopolitan, highly vocal species. Investigated here are their vocalizations recorded at the Vema Seamount (31°38′S, 08°20′E) from moored hydrophones in the austral spring of 2019. During the 11-d recording period over 600 non-song

Estimates of humpback and minke whale entanglements in the Scottish static pot (creel) fishery

Endangered Species Research, 2022
Entanglement in static fishing gear (pots, or creels as they are called in Scottish fisheries) is a major cause of anthropogenic mortality and morbidity in large whales globally; in northeastern Atlantic waters around the coast of Scotland, entanglement ...

A trans-Pacific movement reveals regular migrations of humpback whales Megaptera novaeangliae between Russia and Mexico

Endangered Species Research, 2023
Humpback whales Megaptera novaeangliae undertake extensive annual migrations, have complex migratory patterns, and have held several mammalian long-distance movement records.

Application of DNA Methylation-Based Age Estimation to Construct an Age Structure of Humpback Whales in a Newly Emerged Wintering Ground Around Hachijojima Island, Tokyo Metropolis, Japan. [PDF]

Ecol Evol
Using a noninvasive DNA methylation (DNAm)–based age estimation method, we investigate the age structure of humpback whales that newly emerged around Hachijojima Island, Tokyo Metropolis, Japan to uncover the role of this area for this species.

Quantifying the energy stores of capital breeding humpback whales and income breeding sperm whales using historical whaling records [PDF]

Royal Society Open Science, 2017
Cetacean energy stores are known to vary according to life history, reproductive status and time of year; however, the opportunity to quantify these relationships is rare. Using a unique set of historical whaling records from Western Australia (1952–1963)

Decreases in encounter rate of endangered Northeast Pacific humpback whales in Southern Costa Rica: Possible changes in migration pattern due to warming events

Frontiers in Marine Science, 2022
Warming events in the Pacific Ocean are becoming more frequent, intense, and on a larger temporal and spatial scale. This has caused critical habitats of marine species to lose their quality and marine organisms respond by modifying their critical ...
