-
(1976-07-30)The genotype frequencies of one-year-old oyster spat (Crassostrea gigas) from parents of known genotype, are compared to the frequencies expected with Mendelian inheritance. The genotypes are characterized at three en ...

(1965-05-12)A technique for estimating gross primary production and respiration of periphyton communities, in situ, in small turbulent streams was developed using a photosynthesis-respiration chamber in a modified "light and dark bo ...
-
(2000-08-02)Processes of metamorphosis, settlement, and growth were examined in Pacific sanddab using field studies and otolith microstructure. This flatfish transforms at large sizes, has a gradual metamorphosis, and settles to a ...
-
(1994-12-12)A new method for encapsulating low-molecular weight, water-soluble substances in lipid-walled microcapsules (LWMs) for delivery to marine bivalves was developed, characterized, and tested. LWMs produced by a spray tech ...

(2002-06-14)This thesis focuses upon whether stressful aspects of an organism's environment are reflected by that organism's shape. It presents an application of the powerful thin-plate spline and relative warp methods from morpho ...
-
(1982-10-18)A tagging study was conducted from June 1978 through January 1982 to provide information on the movements of adult neritic reef fishes off the central Oregon coast. To evaluate the cause of low tag returns of previous ...
-
(2011-06-16)Bycatch, or the incidental capture of non-target species, has been implicated as one of the main factors leading to population declines of many large marine vertebrates, including sea turtles. To effectively manage and c ...
