Geographic Distribution, Physiological Adaptations, Systematics and Ecology of Stream Macroalgae in North America
chercheur principal: Sheath, Robert
Année(s) de permis: 1994 1992
Résumé: The researcher and his team will survey streams for macroscopic algae, and relate their distribution to various physical and chemical characteristics, biomes and drainage basins. They will also set up a seasonal study of the physiological adaptations of macroalgae to the harsh conditions of tundra streams. As well, a widespread seaweed will be collected for comparison with other populations to d...


Freshwater Red Algae in North America
chercheur principal: Sheath, Robert
Année(s) de permis: 1987
Résumé: To clarify freshwater red algae classification by determining key stable and non-overlapping structural characteristics needed to clearly separate species. Collecting trips will be made to all major drainage basins of the Atlantic, Pacific and Arctic. Preserved samples will be analyzed by computerized microscopy and live samples will be cultured under varied growth conditions to induce potential ...
