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

PLoS 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
Acta 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.

Effect of solar radiation on cetaceans [PDF]
, 2011 PhDDespite the marked deceleration in the amount of ozone lost at the poles each year, high levels of solar ultraviolet radiation (UVR) continue to reach our biosphere, potentially threatening living organisms, which owing to their life-histories and ...

A phylogenomic analysis of the role and timing of molecular adaptation in the aquatic transition of cetartiodactyl mammals [PDF]
Royal Society Open Science, 2015 Recent studies have reported multiple cases of molecular adaptation in cetaceans related to their aquatic abilities. However, none of these has included the hippopotamus, precluding an understanding of whether molecular adaptations in cetaceans occurred ...

Animals, 2022 Pain, usually caused by a strong or disruptive stimulus, is an unpleasant sensation that serves as a warning to organisms. To adapt to extreme environments, some terrestrial animals have evolved to be inherently insensitive to pain.

Intestinal Volvulus in Cetaceans [PDF]
Veterinary Pathology, 2012 Intestinal volvulus was recognized as the cause of death in 18 cetaceans, including 8 species of toothed whales (suborder Odontoceti). Cases originated from 11 institutions from around the world and included both captive ( n = 9) and free-ranging ( n = 9) animals. When the clinical history was available ( n = 9), animals consistently demonstrated acute

Functional Roles and Ecological Importance of Small Cetaceans in Aquatic Ecosystems
Frontiers 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 ...
