Mortality of sea lions along the central California coast linked to a toxic diatom bloom
TLDR
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. Expand
Relationship between Fish Size and Otolith Length for 63 Species of Fishes from the Eastern North Pacific Ocean
TLDR
The relationship between fish length and fish weight, and between otolith length andFish length was linear, and most of the variability was explained by a simple least-squares regression. Expand
Assessment of errors associated with harbour seal (Phoca vitulina) faecal sampling
TLDR
Correct correction factors were developed which will allow researchers to estimate more reliably number and size of fish and cephalopod prey eaten by harbour seals. Expand
Nitrogen isotope fractionation in amino acids from harbor seals: implications for compound-specific trophic position calculations
Compound-specific isotope analysis of individual amino acids (AA) is a rapidly growing tool in ecological studies to assess diet and trophic position (TP) in both modern and ancient foodwebs. WeExpand
Foraging behavior of humpback whales: kinematic and respiratory patterns suggest a high cost for a lunge
TLDR
High-resolution digital tags on foraging humpback whales used to determine the number of lunges executed per dive as well as respiratory frequency between dives suggest that the high energetic cost associated with lunge feeding in blue and fin whales also occurs in intermediate sized rorquals. Expand
GENETIC SUBSTRUCTURE OF THE PACIFIC HARBOR SEAL (PHOCA VITULINA RICHARDSI) OFF WASHINGTON, OREGON, AND CALIFORNIA
TLDR
Phylogenetic analysis indicated Puget Sound seals possess unique divergent lineages not found in seals from the coasts of Washington, Oregon, and California, which is consistent with late reproductive timing of harbor seals from Pugets Sound. Expand
Preliminary studies on the age and growth of blue (Prionace glauca), common thresher (Alopias vulpinus), and shortfin mako (Isurus oxyrinchus) sharks from California waters
TLDR
The results and other available information indicate that these elasmobranchs grow relatively slowly, reaching their asymptotic lengths at 20 yr of age for blue sharks, and between 45 and 50 yr for shortfin mako and common thresher sharks. Expand
Seabirds as indicators of marine ecosystems
TLDR
A key requirement for implementing ecosystembased management is to obtain timely information on significant fluctuations in the ecosystem, but analyses of time series data suggest otherwise: physical data are more erratic than biological data. Expand
Variability in reactions of Pacific harbor seals, Phoca vitulina richardsi, to disturbance
TLDR
In many locations, disturbance is an important factor affecting the haulout patterns of harbor seals, Phoca vitulina, and the effects of disturbance may be quite mild or may cause displacement and even mortality. Expand
Changes in the cetacean assemblage of a coastal upwelling ecosystem during El Niño 1997–98 and La Niña 1999
Abstract We report results of ecosystem studies in Monterey Bay, California, during the summer upwelling periods, 1996–99, including impacts of El Nino 1997–98 and La Nina 1999. Random-systematicExpand
