Due to the development, Japan lost more than half of seaweed beds
because of reclamations, water brake constructions and water pollution
after the WWII. As a result, coastal fisheries production decreased from 2
million metric tons to 1.5 million metric tons. Building a forest in the sea
has been paid...
Clinocardium nuttallii from Yaquina Bay, Oregon, were found to
harbor an algal symbiont in the siphon, mantle and occasionally
the foot tissues. Approximately 35 percent of the population in the
study area was infected to some degree with the alga; however, no
cockles under two years of age were infected....
The term "interaction" in evolutionary biology and ecology
describes the relationships among variables in two classes of causal
models. In the first, "interaction" refers to the influence of a
single putatively causal variable on a variable of interest. In the
second class of models, the term applies when a third...
Hansen, Gayle I. 1989. Nori farming in Anacortes, Washington: a political dilemma. A poster presented at the 13th International Seaweed Symposium (Vancouver, British Columbia) and the 4th Northwest Algal Symposium (Rosario Beach, Washington). In 1987, the off-shore cultivation of the nutritious seaweed, nori or Porphyra (Pyropia), had been studied intensely...
Aspects of the life history and ecology of the intertidal turf-forming
alga Rhodomela larix (Turner) C. Agardh were examined over a two
year period at several sites on the Oregon coast. Rhodomela occurred
over a broad tidal range and exhibited different growth and morphology
characteristics with respect to tidal height....
Following surveys of seaweeds in Oregon and the Caribbean, four algal species were selected for study on the basis of their crude extract biological activity or thin-layer chromatographic characteristics. Extracts were fractionated by normal phase chromatography, including high performance liquid chromatography (HPLC). Derivatives (methyl esters, acetates, and benzoates) of natural...
I have participated in a drug discovery program designed to screen marine algae for
inhibitors of cancer-related enzymes, antitumor compounds, antiinflammatory substances,
and other agents of potential pharmaceutical utility. Over 1,500 lipid and aqueous extracts
of marine plants and animals were surveyed for biomedical potential. Assays designed to
screen extracts...
