Borealodon osedax, a new stem mysticete (Mammalia, Cetacea) from the Oligocene of Washington State and its implications for fossil whale-fall communities [PDF]

open access: yesRoyal Society Open Science, 2019
Baleen whales (mysticetes) lack teeth as adults and instead filter feed using keratinous baleen plates. They do not echolocate with ultrasonic frequencies like toothed whales but are instead known for infrasonic acoustics.

Assessing the viability of estimating baleen whale abundance from tourist vessels

open access: yesFrontiers in Marine Science, 2023
Many populations of southern hemisphere baleen whales are recovering and are again becoming dominant consumers in the Southern Ocean. Key to understanding the present and future role of baleen whales in Southern Ocean ecosystems is determining their ...

Adapting to a warmer ocean – seasonal shift of baleen whale movements over three decades [PDF]

open access: yes, 2015
Date of Acceptance: 11/02/2015Global warming poses particular challenges to migratory species, which face changes to the multiple environments occupied during migration. For many species, the timing of migration between summer and winter grounds and also

A new archaic baleen whale Toipahautea waitaki (early Late Oligocene, New Zealand) and the origins of crown Mysticeti [PDF]

open access: yesRoyal Society Open Science, 2018
A new genus and species of extinct baleen whale †Toipahautea waitaki (Late Oligocene, New Zealand) is based on a skull and associated bones, from the lower Kokoamu Greensand, about 27.5 Ma (local upper Whaingaroan Stage, early Chattian).

Stable isotopes (δ15N and δ13C) from the baleen of North Atlantic minke whales (Balaenoptera acutorostrata)

open access: yes, 2021
This data set contains stable isotope values (δ15N and δ13C) from the baleen of fifteen North Atlantic minke whales (Balaenoptera acutorostrata). The whales were taken under scientific permit from the Norwegian Ministry of Fisheries, as part of the ...

Stable Isotope Oscillations in Whale Baleen Are Linked to Climate Cycles, Which May Reflect Changes in Feeding for Humpback and Southern Right Whales in the Southern Hemisphere

open access: yesFrontiers in Marine Science, 2022
Baleen whales that undertake extensive long-distance migrations away from reliable food sources must depend on body reserves acquired prior to migration. Prey abundance fluctuates, which has been linked in some regions with climate cycles. However, where

Long-term frequency changes of a potential baleen whale call from the central Indian Ocean during 2002–2019 [PDF]

open access: yesJASA Express Letters, 2021
The multiple baleen whales of the central Indian Ocean use distinct calls, with their acoustic signatures marking their respective geographic distributions.

Molecular markers in keratins from Mysticeti whales for species identification of baleen in museum and archaeological collections.

open access: yesPLoS ONE, 2017
Baleen has been harvested by indigenous people for thousands of years, as well as collected by whalers as an additional product of commercial whaling in modern times.

The Introduction and Development of Plate Armour in Medieval Western Europe c. 1250-1350

open access: yesFasciculi Archaeologiae Historicae, 2017
European underwent a period of rapid development and experimentation in the century after c. 1250. Whilst very little physical material has survived from this time, artistic depictions, wills, inventories and contemporary accounts attest to the use of ...

Estimating blue whale skin isotopic incorporation rates and baleen growth rates: Implications for assessing diet and movement patterns in mysticetes. [PDF]

open access: yesPLoS ONE, 2017
Stable isotope analysis in mysticete skin and baleen plates has been repeatedly used to assess diet and movement patterns. Accurate interpretation of isotope data depends on understanding isotopic incorporation rates for metabolically active tissues and ...
