Evolutionary Mechanisms of Coagulation Factors in Cetaceans During Aquatic Adaptation

Integrative Zoology, EarlyView.
Compared with Bos taurus, T. truncatus showed shorter prothrombin time and thrombin time but prolonged activated partial thromboplastin time, indicating pathway‐specific remodeling of coagulation. Evolutionary analyses identified 18 positively selected genes and accelerated F11 evolution, while functional assays revealed increased coagulation factor ...

Comparative review of entanglement risk assessments for cetacean conservation and management

Conservation Biology, EarlyView.
Abstract Cetacean entanglement in fishing gear remains a major global threat that exposes persistent gaps in how fisheries management frameworks manage risk to nontarget species. Ecological risk assessment (ERA) offers a structured way to link exposure and consequences to an explicit statement of risk, but entanglement risk assessments vary widely in ...

Heterodonty in the teeth of the turiasaurian sauropod from Angeac‐Charente (Early Cretaceous, southwestern France): Comparison of anatomical and geometric morphometric approaches

Journal of Anatomy, EarlyView.
Turiasaurian teeth from Angeac‐Charente exhibit five dental morphotypes and reveal clear heterodonty and anteroposterior size gradient. Qualitative comparative anatomy quickly and efficiently identifies morphotypes, while 3D geometric morphometrics combined with machine learning refine ambiguous cases, demonstrating that qualitative and quantitative ...

Anatomy and Functional Morphology of the Mysticete Rorqual Whale Larynx: Phonation Positions of the U‐Fold

The Anatomical Record, 2018
Many Mysticetes (baleen whales) are acoustically active marine mammals. This is epitomized by rorquals, and specifically male humpback whales (Megaptera novaeangliae) whose complex songs comprise a wide range of vocalizations.

New evidence of a toothed mysticete from the Vaqueros Formation of California fills a gap in the palaeobiogeographic range of Aetiocetidae

Royal Society Open Science
Extant baleen whales (Mysticeti) are toothless aquatic predators that use keratinous baleen plates to capture and filter smaller prey. Although all present-day baleen whales are edentulous obligate filter feeders, the fossil record documents several ...

Seasonal and Diel Acoustic Occurrence of Sei Whales in Oregon, USA

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The behavior, distribution, and life history of sei whales (Balaenoptera borealis) are largely unknown in the North Pacific. We analyzed data from three bottom‐mounted acoustic recorders deployed 25 (shelf; depth = 300 m), 45 (slope; depth = 630 m), and 65 (abyssal; depth = 2860 m) nautical miles off of Newport, Oregon, USA that recorded ...
