"October 1, 1979 to September 30, 1980." "We continued our studies on the clam resources in Oregon's estuaries. Our objectives were: (1) to monitor the commercial harvest of subtidal clams in Yaquina and Coos bays and evaluate the effects of mechanical harvest on subtidal clam populations and habitat; (2) to...
"Annual report : October 1, 1980 to September 30, 1981" "During the year we continued our studies on the clam resources in Oregon's estuaries. Our objectives were: to collect data for developing a scientifically sound clam management database and to refine techniques for assessing the potential for a commercial clam...
Covers July 1, 1970 to June 30, 1971. Reports on studies of spawning and larval rearing of Manila littleneck clams, native littleneck clams, butter clams and gaper clams, including field work. "Field studies comparing growth and survival of laboratory-reared and imported Pacific and Kumamoto oysters were completed. We continued studies...
"We continued our studies of the distribution of bay clams in Oregon's estuaries, Maps showing the distribution of clams and vegetation type in Umpqua and Coos bays are presented. . . We continued to monitor the growth of laboratory produced clams planted in Netarts and Yaquina bays." (from the Abstract)...
The resurgence of cucurbit downy mildew has dramatically influenced production of cucurbits and disease management systems at multiple scales. Long-distance dispersal is a fundamental aspect of epidemic development that influences the timing and extent of outbreaks of cucurbit downy mildew. The dispersal potential of Pseudoperonospora cubensis appears to be limited...
In marine ecosystems, rising atmospheric CO2 and climate change are associated with concurrent shifts in temperature, circulation, stratification, nutrient input, oxygen content, and ocean acidification, with potentially wideranging biological effects. Population-level shifts are occurring because of physiological intolerance to new environments, altered dispersal patterns, and changes in species interactions. Together...
Clinicians make a variety of judgments about their clients, from judging personality traits to making diagnoses, and a variety of methods are available to do so, ranging from observations to structured interviews. A large body of work demonstrates that from a brief glimpse of another’s nonverbal behavior, a variety of...
"COMPLETION REPORT: July 1, 1970 to June 30, 1973" Work included laboratory and field studies of Manila littleneck clams. The work also included spawning experiments on red abalone, and monitoring of test plots of abalone.
"Laboratory studies during the 1971-72 project year consisted primarily of developing mass culture and planting techniques for Manila littleneck clams (Venerupis semidecussata). Field studies continued utilizing laboratory-reared juvenile Manilas... Adult red abalone (Haliotis rufescens) were obtained from California for spawning. Experiments were initiated for culturing diatoms in the laboratory as...
