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.

Anthropogenic Sound Exposure-Induced Stress in Captive Dolphins and Implications for Cetacean Health

Frontiers in Marine Science, 2021
Many cetaceans are exposed to increasing pressure caused by anthropogenic activities in their marine environment. Anthropogenic sound has been recognized as a possible stressor for cetaceans that may have impacts on health.

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 ...

Rubbing Salt in the Wound: Molecular Evolutionary Analysis of Pain-Related Genes Reveals the Pain Adaptation of Cetaceans in Seawater

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.

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 ...

Gene duplications and gene loss in the epidermal differentiation complex during the evolutionary land-to-water transition of cetaceans

Scientific Reports, 2021
Major protein components of the mammalian skin barrier are encoded by genes clustered in the Epidermal Differentiation Complex (EDC). The skin of cetaceans, i.e.

Urgent assessment needed to evaluate potential impacts on cetaceans from deep seabed mining

Frontiers in Marine Science, 2023
Deep seabed mining operations, if permitted, could present significant risks to ocean ecosystems. Disturbance on any scale is likely to be long lasting and irreversible.

Factors associated with the differential distribution of cetaceans linked with deep habitats in the Western Mediterranean Sea

Scientific Reports, 2022
Deep-habitat cetaceans are generally difficult to study, leading to a limited knowledge of their population. This paper assesses the differential distribution patterns of three deep-habitat cetaceans (Sperm whale—Physeter macrocephalus, Risso’s dolphin ...

Sightings of Cetaceans in the waters of Yuzhny Sea Port (Hryhorivsky Estuary, Black Sea) in 2015–2016 [PDF]

Праці Теріологічної школи, 2016
The use of transformed coastal ecosystems by the Black Sea cetaceans is an important, but little studied issue. In 2015–2016, coastal visual observations of cetaceans were conducted in the waters of Yuzhny Sea Port.

First Unmanned Aerial Vehicle Observation of Epimeletic Behavior in Indo-Pacific Humpback Dolphins

Animals, 2022
Epimeletic behavior has been reported in various species of cetaceans and sometimes in wild populations during vessel-based surveys. Epimeletic behavior in cetaceans involves complex social interactions which have been described using observational and ...
