| Summary: | The intent of this study is to describe and analyze the interrelations of vegetation and environment in the east-central sector of the Mackenzie River Delta, Northwest Territories. It traces the sequence and function of the allogenic events which create varying habitat systems and determines whether environmental modification, once initiated on terra nova is directional - in either a physical or floristic expression. In determining the sequence and influence of physical environmental factors, the following parameters were measured, employing standard instruments and field investigation techniques: micro-relief; depth, areal extent, and duration of flooding; thickness, areal extent, and particle-size distribution of annual deposits of alluvium; magnitude and significance of erosion; patterns of microclimatic variation (including air temperature and humidity, evaporativity, precipitation, wind speed, solar radiation, and net radiation); lake and channel temperatures; soil pH, moisture (hygrotope class), and ... |
