Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model
Integrative Zoology, EarlyView.UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

Ultrasonographic Ocular Biometry of the Greater Caribbean Manatee (Trichechus manatus manatus)
Veterinary Ophthalmology, EarlyView.ABSTRACT This study aimed to characterize the ocular biometry of the Trichechus manatus manatus applying B‐mode ultrasonography across different age groups. Twenty‐two animals were assessed employing a portable ultrasound device equipped with a linear transducer. Five ocular parameters were assessed: corneal thickness (CT), anterior chamber depth (ACD),

Boater Manatee Awareness System [PDF]
, 2002 A variety of see-in-the-dark technologies have been evaluated with the objective of adapting them to detect Florida manatee (Trichechus manatus latirostris) aggregations in specific highuse areas, such as warm water refuges in the winter time.

A New Miocene Sirenian from Kutch, India [PDF]
Acta Palaeontologica Polonica, 2009 We report a new Miocene sirenian from District Kutch, State of Gujarat, India: Domingia sodhae gen. et sp. nov. The new species is a dugongine dugongid with flattened tusk-like upper incisors. Like some other Miocene dugongids, Domningia is large and has complex, bilophodont molars and three-rooted premolars, which are strongly worn.
