Severe Hearing Loss in the World's First Successfully Captive‐Born Yangtze Finless Porpoise: Impact of High Underwater Sound Exposure and Congenital Hearing Disorders

Integrative Zoology, EarlyView.
The audiogram of the world's first successfully captive‐born Yangtze finless porpoise was on average 40 dB higher than conspecifics. Congenital hearing disorders and noise exposure may be the primary cause of porpoise's hearing loss. ABSTRACT Aquariums globally have seen significant growth in recent decades.

Microhaplotype Methods Enable Relationship Inference in a Bottlenecked Mammalian Species

Animal Conservation, EarlyView.
Northern elephant seals (Mirounga angustirostris) are among the most genetically depauperate mammals in the world. A near‐total population bottleneck in the 19th century, coupled with the breeding system of extreme polygyny, has challenged efforts to estimate individual reproductive success with genetic methods.

Variation of blubber thickness for three marine mammal species in the southern Baltic Sea

Frontiers in Physiology, 2022
Evaluating populational trends of health condition has become an important topic for marine mammal populations under the Marine Strategy Framework Directive (MSFD). In the Baltic Sea, under the recommendation of Helsinki Commission (HELCOM), efforts have

Modelling the effect of varying metabolic rate and cardiac output on estimated tissue and blood O2 and CO2 levels in an extreme deep‐diver, the goose‐beaked whale (Ziphius cavirostris)

Experimental Physiology, EarlyView.
Abstract High‐resolution movement data from Cuvier's beaked, or goose‐beaked whale (Ziphius cavirostris, hereafter Ziphius, n = 8) tag deployments (4.1–19.2 days) were used to estimate blood and tissue O2 and CO2 levels. Acceleration and magnetometry data were used to estimate the locomotion cost (LC) from the relationship between activity and the O2 ...

Cetacean Strandings in the US Pacific Northwest 2000–2019 Reveal Potential Linkages to Oceanographic Variability

Frontiers in Marine Science, 2022
Studying patterns in marine mammal stranding cases can provide insight into changes in population health, abundance, and distribution. Cetaceans along the United States West coast strand for a wide variety of reasons, including disease, injury, and poor ...
