Nasopulmonary mites (Acari: Halarachnidae) as potential vectors of bacterial pathogens, including Streptococcus phocae, in marine mammals

open access: yesPLoS ONE, 2022
Nasopulmonary mites (NPMs) of the family Halarachnidae are obligate endoparasites that colonize the respiratory tracts of mammals. NPMs damage surface epithelium resulting in mucosal irritation, respiratory illness, and secondary infection, yet the role ...

Suite of simple metrics reveals common movement syndromes across vertebrate taxa [PDF]

open access: yes, 2017
ecause empirical studies of animal movement are most-often site- and species-specific, we lack understanding of the level of consistency in movement patterns across diverse taxa, as well as a framework for quantitatively classifying movement patterns. We

Fatty acids in plasma of California sea lion pups (Zalophus c. californianus) from Los Islotes, Baja California Sur, Mexico

open access: yesCiencias Marinas, 2003
 Nutritious fats include all the lipids ingested as food and are composed mainly of triglycerides mixed with smaller quantities of other lipids. Fatty acids (FA) constitute the part of most nutritious interest in triglycerides.

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

open access: yesEcol 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.
