Humpback whale adult females and calves balance acoustic contact with vocal crypsis during periods of increased separation

open access: yesEcology and Evolution, 2022
Acoustic communication is important for animals with dependent young, particularly when they are spatially separated. Maternal humpback whales (Megaptera novaeangliae) use acoustic calling to help minimize the risk of separation from their young calves ...

Cetacean Host-Pathogen Interaction(s): Critical Knowledge Gaps [PDF]

open access: yes, 2018
Within the broad range of viral and non-viral pathogens infecting cetaceans, Cetacean Morbillivirus (CeMV), Herpesvirus (HV), Brucella ceti, and Toxoplasma gondii are of special concern, due to their impact(s) on the health and conservation of free ...

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

Isotopic Niche Analysis of Long-Finned Pilot Whales (Globicephala melas edwardii) in Aotearoa New Zealand Waters

open access: yesBiology, 2022
The quantification of a species’ trophic niche is important to understand the species ecology and its interactions with the ecosystem it resides in. Despite the high frequency of long-finned pilot whale (Globicephala melas edwardii) strandings on the ...

Acoustic and visual cetacean surveys reveal year-round spatial and temporal distributions for multiple species in northern British Columbia, Canada

open access: yesScientific Reports, 2022
Cetaceans spend most of their time below the surface of the sea, highlighting the importance of passive acoustic monitoring as a tool to facilitate understanding and mapping their year-round spatial and temporal distributions.

Range-Wide Conservation Efforts for the Critically Endangered Atlantic Humpback Dolphin (Sousa teuszii)

open access: yesDiversity, 2022
The Atlantic humpback dolphin (Sousa teuszii) is a critically endangered cetacean species endemic to coastal Atlantic waters of Africa. Its preference for shallow coastal habitat renders it vulnerable to incidental capture (bycatch) in non-selective ...

Intestinal Volvulus in Cetaceans [PDF]

open access: yesVeterinary 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

Rapid immune colloidal gold strip for cetacean meat restraining illegal trade and consumption: implications for conservation and public health. [PDF]

open access: yesPLoS ONE, 2013
The consumption of cetacean meat is geographically common and often of undetermined sustainability. Besides, it can expose humans to contaminants and zoonotic pathogens.

Socially Complex Breeding Interactions in Humpback Whales Are Mediated Using a Complex Acoustic Repertoire

open access: yesFrontiers in Marine Science, 2021
Intraspecific conflict can be costly; therefore, many species engage in ritualized contests composed of several stages. Each stage is typically characterized by different levels of aggression, arousal, and physical conflict. During these different levels

Identification of Novel Cetacean Poxviruses in Cetaceans Stranded in South West England. [PDF]

open access: yesPLoS ONE, 2015
Poxvirus infections in marine mammals have been mainly reported through their clinical lesions and electron microscopy (EM). Poxvirus particles in association with such lesions have been demonstrated by EM and were previously classified as two new ...
