Effects of vegetation and soil organisms on soil nutrient dynamics in subalpine Abies lasiocarpa forests

Creator:

Johnson, Kathleen A., 1955-

Abstract:

The broadest goal of the research covered in this thesis was to contribute to our limited knowledge of high elevation forest soil ecology. Based on the reeds of funding agencies, specific objectives were to examine 1) how climate-induced Abies lasiocarpa ([Hook.] Nutt.) forest expansion affects soil nutrient pools, 2) the...

Effects of cork bark disease on cambial activity and secondary tissues in Abies lasiocarpa (Hook.) Nutt

Creator:

Carr, John Edward, 1943-

Abstract:

Abies lasiocarpa (Hook.) Nutt. (sub-alpine fir) trees of comparable vigor growing in eastern British Columbia were studied in order to determine the effects of cork bark disease on phellogen and vascular cambium activity. Diseased trees form hard deeply fissured rhytidome several inches thick over large areas of the bole when...
