Vocal production learning is the ability to modify a vocal output in response to auditory experience. It is essential for human speech production and language acquisition. Vocal learning evolved independently several times in vertebrates, indicating evolutionary pressure in favor of this trait. This enables cross-species comparative analysis to be used

Cetacean loss of the master adipose tissue regulator β3-adrenergic receptor may underlie their thick blubber and an Oligocene radiation and dispersal [PDF]
Blubber is a hydrostatic pressure-resistant and insulating vascularized layer of subcutaneous adipose tissue beneath the skin found in cetaceans, pinnipeds, and sirenians.

Vulnerability of marine megafauna to global at-sea anthropogenic threats. [PDF]
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

Ultrasonographic Ocular Biometry of the Greater Caribbean Manatee (Trichechus manatus manatus). [PDF]
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),

Life Expectancy in Marine Mammals Is Unrelated to Telomere Length but Is Associated With Body Size
Marine mammals vary greatly in size and lifespan across species. This study determined whether measures of adult body weight, length and relative telomere length were related to lifespan.

Congenital Ocular Findings in an Antillean Manatee (Trichechus manatus manatus). [PDF]
This study reports the first documented case of bilateral congenital cataract associated with retinal dysplasia in an Antillean manatee (Trichechus manatus manatus) calf. Ophthalmologic examination and ocular ultrasonography confirmed lens opacity at the posterior pole, which correlated with behavioural deficits consistent with visual impairment.
