Variation of carbon allocation and competitive ability of different tree species as related to successional position and habitat

Creator:

Malavasi, Ubirajara Contro

Abstract:

Early and late seral tree species were compared for inter-and intraspecific competitive ability; within-population genetic variability; and allocation patterns of soluble sugars and starch seasonally and in response to shade and nitrogen fertilization. Species were Douglas-fir (early seral) and western hemlock (late seral) from a low elevation habitat; and noble...

Early plant biomass trends following forest site preparation on the Oregon Coast Range

Creator:

Malavasi, Ubirajara Contro

Abstract:

The vegetation following forest site preparation was examined in ten clearcut units located in the western Oregon Coast Range. The site preparation techniques used in these units included scarification, slash burning, and chemical spraying. The ages of the clearcut units studied varied from one to nine growing seasons for the...
