This study examines the interactions between explosive environmental contaminants and marine seaweeds. The scope of this thesis includes studies done on the explosive RDX with tissue cultures of marine seaweeds, as well as studies on the explosive TNT with seaweed extracts.
The ability of two different marine species of macroalgae...
The influence of the physical environment on organisms has long been a subject of ecological research. But, the complex drivers of environmental variation, and the multiple scales at which this can occur, make studying this topic a difficult challenge. In rocky intertidal habitats, oceanographic- and climate-scale variability influence benthic communities...
Many phytoplankton and macroalgae release dissolved organic carbon (DOC). Many macroalgae also produce and store secondary metabolites which in some case have been shown to deter their grazers. The metabolites may be released into the surrounding seawater and could inhibit primary production. On the other hand, some phytoplankton can use...
Mankind is facing the spectre of a planet stripped of the resources necessary to sustain the human populations that currently exist-not to mention those unborn multitudes which seem certain to he added in the coming decades. Time is rapidly running out for scientists and engineers to find new resources to...
This thesis is an investigation of the natural products deriving from marine algae and cyanobacteria and has resulted in the discovery of eleven new secondary metabolites. The structure elucidations of these new molecules were performed using a variety of spectroscopic techniques. Four new macrolides were isolated and characterized from the...
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....
Dislodged macroalgae and seagrasses, also known as marine wrack, frequently wash into coastal ecosystems from the ocean and are potentially important ecological resources for biological communities. These!nutrient and organic matter subsidies may be especially important on sandy beaches, where little in situ primary productivity exists for higher trophic levels. To...
