The seasonal concentration, turnover and mode of accumulation
of ³²P by the juvenile starry flounder in Alder Slough, a small eco-system in the Columbia River Estuary, was examined during 1969 and
1970.
Levels of ³²P and concentrations of total P were measured to
permit computation of specific activities (nCi³²P/g total...
Four species of euryhaline teleosts (chinook salmon, Oncorhynchus
tshawytscha, Walbaum; staghorn sculpin, Leptocottus armatus,
Girard; starry flounder, Platichthys stellatus, Pallas; shiner perch
Cymatogaster aggregata, Gibbons) were exposed to x-rays. The irradiated
animals were maintained in either of two different environments.
The effects of x-radiation were determined by observing the
percent...
Sampling with seine and trawl from May 1974 to November 1976 indicated that the species composition and distribution of fishes in Tillamook Bay through time is primarily related to the movements of marine species in and out of the estuary. Northern anchovy (Engraulis mordax), surf smelt (Hypomesus pretiosus), and shiner...
The genome composition and DNA base sequence homologies
of several diverse species of fish were examined. The fishes were
characterized from spectrophotometric studies of reassociation and
hybridization of their DNAs and from the thermal stabilities of hybrid
duplexes.
Spectrophotometric studies indicated that repeated sequences
comprise 35-40% of the genomes of...
