First report of a severe nasopulmonary acariasis caused by Orthohalarachne diminuata Doetschman, 1944 (Acari: Halarachnidae) in a captive South American sea lion (Otaria flavescens Shaw, 1800) [PDF]

International Journal for Parasitology: Parasites and Wildlife, 2022
Obligatory endoparasitic mites of the genera Halarachne Allman, 1847 and Orthohalarachne Newell, 1947 (Acari: Halarachnidae) parasitize different segments of the respiratory tract of marine mammals, including pinnipeds and sea otters, and infestations ...

Targeted Nutritional Metabolomic Analysis of Marine Species (Tursiops truncatus, Phoca vitulina, Otaria flavescens and Pygoscelis papua) [PDF]

Veterinary Medicine and Science
Ecological nutrition aims to unravel the extensive web of nutritional links that drive animals in their interactions with their habitat. Metabolomic profiling of species could increase the knowledge of their ecology, as well as allowing us to better ...

Mating Attempts and Sustained Interest Behaviors of Wild Boars (<i>Sus scrofa</i>) Toward a Dead Conspecific. [PDF]

Ecol Evol
We documented behavioral responses of wild boars (Sus scrofa) to a conspecific carcass using camera traps throughout the full decomposition process. One adult male exhibited necrophilic behavior and sustained non‐feeding interactions with the carcass, highlighting pronounced individual variation.

Immunolocalization of Two Neurotrophins, NGF and BDNF, in the Pancreas of the South American Sea Lion Otaria flavescens and Bottlenose Dolphin Tursiops truncatus [PDF]

Animals
In this study, we have investigated the immunolocalization of NGF (Nerve Growth Factor) and BDNF (Brain-Derived Neurotrophic Factor) in the pancreas of two species of marine mammals: Tursiops truncatus (common bottlenose dolphin), belonging to the order ...

Respiratory function in voluntary participating Patagonia sea lions in sternal recumbency [PDF]

Frontiers in Physiology, 2016
We measured esophageal pressures (n=4), respiratory flow rates (n=5), and expired O2 and CO2 (n=4) in five adult Patagonia sea lions (Otaria flavescens, body mass range 94.3-286.0 kg) during voluntary breaths while laying down.

Rare Record of Albinism in a New Zealand Fur Seal (<i>Arctocephalus forsteri</i>) Pup With Observations Through the Weaning Period. [PDF]

Ecol Evol
This article provides the first known scientific record of albinism in a New Zealand fur seal pup. We describe the individual with a particular focus on its sensory abilities. This individual's birth at a central mainland colony may permit continued study throughout his life, unlike many records of similar conditions in other species.
