Ecological effects of populations of the salp Cyclosalpa bakeri were studied in late summer of 1984, 1987 and 1988 dunng the Subarctic Pacific Ecosystem Research (SUPER) project at Station P in the northeast Pacific. S ...

Field and laboratory work was undertaken in 1993 to increase understanding of the life history and ecology of the brown jellyfish, Chrysaora fuscescens, a large semaeostome typically abundant in the neritic regions of t ...

The Galapagos Islands, located off the coast of Ecuador, have a spatially diverse marine environment suitable for a variety of species with different climatic requirements. A year-long inventory program was carried out i ...

Bimonthly plankton samples were collected from 1969 through 1971 along a transect off the central Oregon continental shelf (44° 39. l'N) to document the species of crab larvae present, their seasonality, and their ons ...

We measured oxygen consumption rates, the activities of citrate synthase (CS) and lactate dehydrogenase (LDH) and protein contents for over 30 species of deep-sea pelagic Copepoda. The lowest oxygen consumption rates wer ...

An attempt has been made to experimentally interbreed Atlantic and Pacific populations of the marine calanoid copepod Acartia clausi Giesbrecht. Breeding between individuals from each population produced many successiv ...

An attempt has been made to interbreed populations of Acartia clausi from Woods Hole, Massachusetts, and Yaquina Bay, Oregon. Individuals from these populations are morphologically similar, but differ somewhat in size. C ...

Stratified bongo net samples taken at depths between 0 and 500 m at Ocean Station “P” in the subarctic Pacific in early July 1971 have been analyzed to determine the vertical structure of the zooplankton community. Distr ...
