Concern for Highly Pathogenic Avian Influenza Spillover into Cetaceans. [PDF]

Viruses
Influenza A virus (IAV) has a wide range of avian and mammalian hosts, leading to disease outbreaks and increasing the risk of panzootics and pandemics.

Accelerated evolution and diversifying selection drove the adaptation of cetacean bone microstructure

BMC Evolutionary Biology, 2019
Background The transition from land to sea by the ancestor of cetaceans approximately 50 million years ago was an incredible evolutionary event that led to a series of morphological, physiological, and behavioral adaptations. During this transition, bone

Decompressive Pathology in Cetaceans Based on an Experimental Pathological Model

Frontiers in Veterinary Science, 2021
Decompression sickness (DCS) is a widely known clinical syndrome in human medicine, mainly in divers, related to the formation of intravascular and extravascular gas bubbles.

The use of active sonar to study cetaceans [PDF]

, 2012
Cetacean species face serious challenges worldwide due to the increasing noise pollution brought to their environment by human activities such as seismic exploration. Regulation of these activities is vaguely defined and uncoordinated.

The molecular evolution of genes previously associated with large sizes reveals possible pathways to cetacean gigantism

Scientific Reports, 2023
Cetaceans are a group of aquatic mammals with the largest body sizes among living animals, including giant representatives such as blue and fin whales.

Insights into body size variation in cetaceans from the evolution of body-size-related genes

BMC Evolutionary Biology, 2019
Background Cetaceans exhibit an exceptionally wide range of body size, yet in this regard, their genetic basis remains poorly explored. In this study, 20 body-size-related genes for which duplication, mutation, or deficiency can cause body size change in

Patterns of enrichment and acceleration in evolutionary rates of promoters suggest a role of regulatory regions in cetacean gigantism

BMC Ecology and Evolution, 2023
Background Cetaceans (whales, porpoises, and dolphins) are a lineage of aquatic mammals from which some species became giants. Only recently, gigantism has been investigated from the molecular point of view.

Cetacean Intracytoplasmic Eosinophilic Globules: A Cytomorphological, Histological, Histochemical, Immunohistochemical, and Proteomic Characterization

Animals, 2023
The nature, etiopathogenesis, and clinicopathologic relevance of the prevalent intracytoplasmic eosinophilic globules (IEGs) within hepatocytes of cetaceans are unknown.

Composition of cetacean communities worldwide shapes their contribution to ocean nutrient cycling

Nature Communications, 2023
Defecation by large whales is known to fertilise oceans with nutrients, stimulating phytoplankton and ecosystem productivity. However, our current understanding of these processes is limited to a few species, nutrients and ecosystems.
