The Bacterial Microbiome in the Small Intestine of Hooded Seals (Cystophora cristata) [PDF]

open access: yesMicroorganisms, 2020
Arctic hooded seals (Cystophora cristata) are monogastric carnivores that go through extreme fasting and re-feeding in early life. They are born isolated on sea ice; suckle high-fat milk for four days and may then fast for up to one month before they ...

Drift diving by hooded seals (Cystophora cristata) in the Northwest Atlantic Ocean. [PDF]

open access: yesPLoS ONE, 2014
Many pinniped species perform a specific dive type, referred to as a 'drift dive', where they drift passively through the water column. This dive type has been suggested to function as a resting/sleeping or food processing dive, and can be used as an ...

Hematologic and plasma biochemical prognostic indicators for stranded free-ranging phocids presented for rehabilitation [PDF]

open access: yesScientific Reports, 2022
This retrospective study used data obtained from medical records of 530 stranded free-ranging harbor (Phoca vitulina), grey (Halichoerus grypus), harp (Pagophilus groenlandicus), and hooded seals (Cystophora cristata) presented to the Marine Mammal ...

The eyes of the deep diving hooded seal (Cystophora cristata) enhance sensitivity to ultraviolet light [PDF]

open access: yesBiology Open, 2015
The mammalian visual range is approximately 400–700 nm, although recent evidence suggests varying ultraviolet (UV) extensions in diverse terrestrial species.

Investigating annual diving behaviour by hooded seals (Cystophora cristata) within the Northwest Atlantic Ocean. [PDF]

open access: yesPLoS ONE, 2013
With the exception of relatively brief periods when they reproduce and moult, hooded seals, Cystophora cristata, spend most of the year in the open ocean where they undergo feeding migrations to either recover or prepare for the next fasting period ...

Transcriptomes of Clusterin- and S100B-transfected neuronal cells elucidate protective mechanisms against hypoxia and oxidative stress in the hooded seal (Cystophora cristata) brain [PDF]

open access: yesBMC Neuroscience, 2022
Background The hooded seal (Cystophora cristata) exhibits impressive diving skills and can tolerate extended durations of asphyxia, hypoxia and oxidative stress, without suffering from irreversible neuronal damage. Thus, when exposed to hypoxia in vitro,

Hooded seal Cystophora cristata foraging areas in the Northeast Atlantic Ocean-Investigated using three complementary methods. [PDF]

open access: yesPLoS ONE, 2017
Identifying environmental characteristics that define the ecological niche of a species is essential to understanding how changes in physical conditions might affect its distribution and other aspects of its ecology.

Experimental Challenge of Atlantic Cod (Gadus morhua) with a Brucella pinnipedialis Strain from Hooded Seal (Cystophora cristata). [PDF]

open access: yesPLoS ONE, 2016
Pathology has not been observed in true seals infected with Brucella pinnipedialis. A lack of intracellular survival and multiplication of B. pinnipedialis in hooded seal (Cystophora cristata) macrophages in vitro indicates a lack of chronic infection in

Tissue distribution of angiotensin-converting enzyme 2 (ACE2) receptor in wild animals with a focus on artiodactyls, mustelids and phocids [PDF]

open access: yesOne Health, 2023
Natural cases of zooanthroponotic transmission of SARS-CoV-2 to animals have been reported during the COVID-19 pandemic, including to free-ranging white-tailed deer (Odocoileus virginianus) in North America and farmed American mink (Neovison vison) on ...

Elevated antioxidant defence in the brain of deep-diving pinnipeds [PDF]

open access: yesFrontiers in Physiology, 2022
While foraging, marine mammals undertake repetitive diving bouts. When the animal surfaces, reperfusion makes oxygen readily available for the electron transport chain, which leads to increased production of reactive oxygen species and risk of oxidative ...
