Navigating Cetacean Mitochondrial Genome Data: Identifying Coverage and Deficiencies in Public Repositories. [PDF]
Mol Ecol ResourABSTRACT Genetic reference databases underpin a wide range of molecular approaches used to study cetacean biodiversity, including environmental DNA (eDNA), yet their reliability depends critically on data completeness, taxonomic accuracy, and metadata quality.

Influence of Solvent Lipid Extraction on Tissue-Specific Carbon Isotopes. [PDF]
Ecol EvolTo assess the impact of solvents on δ13C, we used a standard lipid extraction protocol on four different pure proteins and humpback whale blubber, a very lipid‐rich tissue. The results showed that the solvents did not have a significant effect on δ13C and δ15N of pure proteins as values largely remained within 0.5‰ of unextracted samples, which is ...

How is the third jaw joint in whales different? Diverse modes of articulation between the jaws of whales. [PDF]
J AnatThis study conducts the first comprehensive morphological investigation of the mandibular symphysis in whales. Using gross anatomical observation and CT cross‐sectional data, we describe diverse joint morphologies across 74 extant and fossil cetacean taxa. Toothed whales exhibit unfused, partially fused, or fully fused symphyses.

In search of the origin of crown Mysticeti. [PDF]
J R Soc N Z, 2023 ABSTRACT Recent research on mysticete fossils from the Late Eocene and Oligocene has revolutionised our understanding of the diversity and evolutionary scenarios for early baleen whales. For example, aetiocetids are a possible, though controversial, lineage that bridges the gap between the toothed and baleen ...

Relationships of cochlear coiling shape and hearing frequencies in cetaceans, and the occurrence of infrasonic hearing in Miocene Mysticeti [PDF]
Fossil Record, 2018 Baleen whales (Mysticeti) are known to use low frequencies (LF; 200 Hz and below) and infrasound (< 20 Hz) for communication. The lowest hearing limits of toothed whales (Odontoceti), which are able to produce ultrasound (> 20 kHz), reach low ...

Fin whale sound reception mechanisms: skull vibration enables low-frequency hearing. [PDF]
PLoS ONE, 2015 Hearing mechanisms in baleen whales (Mysticeti) are essentially unknown but their vocalization frequencies overlap with anthropogenic sound sources. Synthetic audiograms were generated for a fin whale by applying finite element modeling tools to X-ray ...

Genomic Insights Into the Evolutionary History of Berardius Beaked Whales: Speciation Driven by Resource Specialization, Gigantism and Thermal Barriers? [PDF]
Mol EcolABSTRACT Understanding the diversity of our oceans is fundamental now more than ever as climate change and human activities put increasing pressure on marine species and ecosystems. Beaked whales (family Ziphiidae) are among the most poorly understood marine mammals, in part due to their affinity to offshore underwater canyons and prolonged diving ...

The early Miocene balaenid Morenocetus parvus from Patagonia (Argentina) and the evolution of right whales [PDF]
PeerJ, 2017 Balaenidae (right and bowhead whales) are a key group in understanding baleen whale evolution, because they are the oldest surviving lineage of crown Mysticeti, with a fossil record that dates back ∼20 million years.

A new balaenopterid whale from the late Miocene of the Southern North Sea Basin and the evolution of balaenopterid diversity (Cetacea, Mysticeti) [PDF]
PeerJ, 2019 Background Balaenopterid mysticetes represent the most successful family-rank group of this clade. Their evolutionary history is characterized by a rich fossil record but the origin of the living genera is still largely not understood. Recent discoveries

Life Expectancy in Marine Mammals Is Unrelated to Telomere Length but Is Associated With Body Size
Frontiers in Genetics, 2021 Marine mammals vary greatly in size and lifespan across species. This study determined whether measures of adult body weight, length and relative telomere length were related to lifespan.
