A satellite-linked tag for the long-term monitoring of diving behavior in large whales

Animal Biotelemetry, 2022
Despite spending most time underwater, the technology in use to track whales over large geographic ranges via satellite has been largely limited to locational data, with most applications focusing on characterizing their horizontal movements. We describe

Poor pulmonary health in Barataria Bay dolphins in the eight years following the Deepwater Horizon oil spill

Frontiers in Marine Science, 2022
The Deepwater Horizon (DWH) disaster resulted in large-scale contamination of bays, sounds, and estuaries in the northern Gulf of Mexico, home to multiple stocks of common bottlenose dolphins (Tursiops truncatus).

Marine mammal hotspots in the Greenland and Barents Seas

, 2021
Environmental change and increasing levels of human activity are threats to marine mammals in the Arctic. Identifying marine mammal hot spots and areas of high species richness are essential to help guide management and conservation efforts.

Eicosanoid biosynthesis in marine mammals [PDF]

The FEBS Journal, 2020
After 300 million years of evolution, the first land‐living mammals reentered the marine environment some 50 million years ago. The driving forces for this dramatic lifestyle change are still a matter of discussion but the struggle for food resources and the opportunity to escape predators probably contributed.

The symptomatology and diagnosis of domoic acid toxicosis in stranded California sea lions (Zalophus californianus): a review and evaluation of 20 years of cases to guide prognosis

Frontiers in Veterinary Science, 2023
IntroductionDomoic acid (DA) is a glutaminergic excitatory neurotoxin that causes the morbidity and mortality of California sea lions (Zalophus californianus; CSL) and other marine mammals due to a suite of effects mostly on the nervous and cardiac ...

Blood Rheology in Marine Mammals [PDF]

Frontiers in Physiology, 2010
The field of blood oxygen transport and delivery to tissues has been studied by comparative physiologists for many decades. Within this general area, the particular differences in oxygen delivery between marine and terrestrial mammals has focused mainly on oxygen supply differences and delivery to the tissues under low blood flow diving conditions. Yet,

Best Practices for Assessing and Managing Bycatch of Marine Mammals

Frontiers in Marine Science, 2021
Bycatch in marine fisheries is the leading source of human-caused mortality for marine mammals, has contributed to substantial declines of many marine mammal populations and species, and the extinction of at least one.

Health Impacts and Recovery From Prolonged Freshwater Exposure in a Common Bottlenose Dolphin (Tursiops truncatus)

Frontiers in Veterinary Science, 2020
Common bottlenose dolphins (Tursiops truncatus) exposed to freshwater or low salinity (<10 practical salinity units; PSU) for prolonged periods of time have been documented to develop skin lesions, corneal edema and electrolyte abnormalities, and in ...

Blood-based indicators of insulin resistance and metabolic syndrome in bottlenose dolphins (Tursiops truncatus)

Frontiers in Endocrinology, 2013
Similar to people with metabolic syndrome, bottlenose dolphins (Tursiops truncatus) can have a sustained postprandial hyperglycemia and hyperinsulinemia, dyslipidemia, and fatty liver disease.
