Objectif(s): To collect lichens for laboratory analyses in order to determine the types and amounts of contaminants that have been introduced into the arctic ecosystem by means of long-distance air transport and assimilated by lichens; to examine plant communities found along the Hood River in order to get an understanding of the effects of climate, geography, hydrology and soils on vegetation.
Description du projet: Project 1: Small samples of lichens will be collected from approximately 20 sites located along the Hood River and analyzed for contaminants. Lichens are good indicators of the types of air-borne contaminants that have been carried north to the arctic since they absorb their nutrients from the air. Project 2: The researcher will examine plant communities along the Hood River in order to study the effects of climate, geography, hydrology and soils on plants.
