Notes: "Dissertation May 1990."

Consists of a summary of earlier investigations and of four previously published papers, I. Calculating net annual accumulation rates of sediment components exemplified by pollen, II. The post-glacial history of vegetation and agriculture in the Luleälv river valley, III. The vegetational and agricultural history of a northern Swedish catchment studied by analyses of varved lake sediments, and IV. Soil pollen analysis-an application for tracing ancient arable patches.
