TL;DR: Findings reveal that monitoring of mussel toxicity alone does not necessarily provide adequate warning of DA entering the food web at levels sufficient to harm marine wildlife and perhaps humans.
Journal ArticleDOI
Diving patterns of California sea lions, Zalophus californianus
TL;DR: The diving patterns of 10 adult female California sea lions were examined during the summer breeding season on San Miguel Island, California, in 1982 and 1983 using time–depth recorders to suggest cost–benefit considerations based on prey availability and encounter rate may be more important than physiological limits in shaping the foraging patterns of Zalophus.
Journal ArticleDOI
Documenting migrations of northern elephant seals using day length
TL;DR: In this article, the authors describe a systeme permettant d'etudier les deplacements pelagiques de l'elephant de mer, which permet, a partir de mesures precises de la photoperiode en fonction de la latitude and de la longitude, d'enregistrer les differentes localisations au cours de la periode passee en mer.
Journal ArticleDOI
Diving patterns of northern elephant seal bulls
TL;DR: This article used microprocessor-based, time-depth recorders to document the diving patterns of six adult male northern elephant seals (Mirounga angustirostris) from San Miguel Island, California.
Journal ArticleDOI
Double Migrations of the Northern Elephant Seal, Mirounga angustirostris
TL;DR: The first double migration for any animal was documented in the northern elephant seal using new tracking technology as mentioned in this paper, which showed that the species (and individuals) returned to the same foraging areas during postbreeding and postmolt movements.
