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

open access: yesViruses
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.

Cetacean loss of the master adipose tissue regulator β3-adrenergic receptor may underlie their thick blubber and an Oligocene radiation and dispersal [PDF]

open access: yesNature Communications
Blubber is a hydrostatic pressure-resistant and insulating vascularized layer of subcutaneous adipose tissue beneath the skin found in cetaceans, pinnipeds, and sirenians.

Pygmy sperm whale multi-omics data reveal hypoxia adaptations in deep-diving cetaceans [PDF]

open access: yesBMC Biology
Background Deep-diving cetaceans tolerate acute hypoxia better than their terrestrial ancestors and shallow-diving counterparts. However, our poor understanding of how genetic factors, cellular functions, and physiological characteristics combine to ...

Evolution of cetacean-specific conserved non-coding elements suggests their role in the limb changes during secondary aquatic adaptation [PDF]

open access: yesBMC Biology
Background Limb morphology is particularly important for animals to inhabit different environments. Limb modifications (e.g., flipper-like forelimbs and hindlimb regression) are among the most critical secondary aquatic adaptation mechanisms enabling ...

First record of a white rough-toothed dolphin (Steno bredanensis) off West Africa including notes on rough-toothed dolphin surface behaviour [PDF]

open access: yes, 2010
In June 2009, a white rough-toothed dolphin (Steno bredanensis) calf was photographed in a group of at least 50 dolphins in the southern Gulf of Guinea, 95 nauticol miles off the Gabon coast (01°45'S 007°29'E), West Africa. Reports of unusually pigmented

The non-consumptive economic value of wildlife: the case of three cetacean species

open access: yesScientia Marina, 2023
The conservation of wildlife is one of the most pressing issues in the current times, but wildlife conservation economic values have often been largely ignored due to an absence of market prices, as setting an economic value on biodiversity or whole ...

Developing cetacean-friendly guidelines, from whale watching to offshore wind farm operation

open access: yesFrontiers in Marine Science, 2023
Developing offshore wind farms may impact cetaceans due to vessel collisions and underwater noise. Therefore, it is critical to protect cetaceans while developing offshore wind farms. We first studied the code of conduct/guidelines for whale watching and

Molecular fossils illuminate the evolution of retroviruses following a macroevolutionary transition from land to water.

open access: yesPLoS Pathogens, 2021
The ancestor of cetaceans underwent a macroevolutionary transition from land to water early in the Eocene Period >50 million years ago. However, little is known about how diverse retroviruses evolved during this shift from terrestrial to aquatic ...

Pathoanatomical findings of a green turtle (Chelonia mydas) victim of collision with a motorboat

open access: yesActa Veterinaria, 2021
In this paper we report the trauma suffered by a green turtle (Chelonia mydas), caused by a collision with a motorboat, and describe the case ante and post-mortem.

Functional Roles and Ecological Importance of Small Cetaceans in Aquatic Ecosystems

open access: yesFrontiers in Marine Science, 2022
Small cetaceans (dolphins, porpoises, and small toothed whales) occur from the poles to the tropics, and from freshwater habitats to the open ocean. Most ecological research has focused on the influence of abiotic factors on the abundance, distribution ...
