Correcting aerial survey counts of harbor seals (phoca vitulina richardsi) in washington and oregon
TL;DR: In this article, VHF radio tags were deployed on harbor seals (n = 124) at six sites in Washington and Oregon, and a correction factor was determined from the proportion of radio-tagged seals on shore during the pupping season.
Journal ArticleDOI
Diel haul‐out patterns and site fidelity of harbor seals (phoca vitulina richardsi) on san miguel island, california, in autumn
TL;DR: Study of the haul-out patterns and movements of harbor seals on San Miguel Island, California, from 23 October through 6 December 1982 by attaching a radio transmitter to each of 18 seals and monitoring their presence ashore with continuously scanning receivers estimated absolute abundance at about 2,168 seals.

TL;DR: Data suggest an interrelationship of disease agents and environmental contaminants as the cause of premature parturition in California sea lion pups born on San Miguel Island.
Journal ArticleDOI
Molecular and morphometric evidence for separate species of Uncinaria (Nematoda: Ancylostomatidae) in California sea lions and northern fur seals: hypothesis testing supplants verification.
TL;DR: Results indicate that these hookworms represent 2 species that are not distributed indiscriminately between these host species, but instead exhibit host fidelity, evolving independently with each respective host species.
