The global extent and severity of operational interactions between conflicting pinnipeds and fisheries [PDF]

open access: yesNature Communications
Recent population recovery of many pinniped species (seals, sea lions, walrus) is a conservation success. However, pinniped population recovery combined with increasing global fisheries operations is leading to increased conflicts between pinnipeds and ...

Common and unique strategies of myoglobin evolution for deep-sea adaptation of diving mammals

open access: yesiScience, 2021
Summary: Myoglobin (Mb) is highly concentrated in the myocytes of diving mammals such as whales and seals, in comparison with land animals, and its molecular evolution has played a crucial role in their deep-sea adaptation.

Amyloid β and tau pathology in brains of aged pinniped species (sea lion, seal, and walrus)

open access: yesActa Neuropathologica Communications, 2021
Alzheimer’s disease (AD) is characterized by the accumulation of amyloid-β (Aβ) as senile plaques and cerebral amyloid angiopathy, and hyperphosphorylated tau (hp-tau) as neurofibrillary tangles in the brain. The AD-related pathology has been reported in

Clawed forelimbs allow northern seals to eat like their ancient ancestors [PDF]

open access: yesRoyal Society Open Science, 2018
Streamlined flippers are often considered the defining feature of seals and sea lions, whose very name ‘pinniped’ comes from the Latin pinna and pedis, meaning ‘fin-footed’. Yet not all pinniped limbs are alike. Whereas otariids (fur seals and sea lions)
