Fine-root dynamics in mixed boreal conifer – broad-leafed forest stands at different successional stages after fire
Fine-root (diameter ≤ 10 mm) standing biomass, length, distribution, production, and decomposition were studied in mixed conifer – broad-leafed forest stands 48, 122, and 232 years after fire on clay soils in the southern boreal forest of Quebec. A combination of ingrowth bags, soil cores, and root litter bags was used. Forest composition changed from trembling aspen(Populus tremuloides Michx.)...
متن کاملDoes the age of fine root carbon indicate the age of fine roots in boreal forests?
To test the reliability of the radiocarbon method for determining root age, we analyzed fine roots (originating from the years 1985–1993) from ingrowth cores with known maximum root age (1–6 years old). For this purpose, three Scots pine (Pinus sylvestris L.) stands were selected from boreal forests in Finland. We analyzed root C age by the radiocarbon method and compared it with the abovementi...
متن کاملRegulation of Fine Root Dynamics by Mammalian Browsers in Early Successional Alaskan Taiga Forests
The effects of browsing by moose and snowshoe hares on fine root production, mortality, and decomposition in early successional forest ecosystems along the Tanana River floodplain in interior Alaska were studied over a 3-yr period using minirhizotrons placed inside and outside large permanent exclosures. Fine root production and mortality varied seasonally, with greatest rates of production occ...
متن کاملLitterfall production and fine root dynamics in cool-temperate forests
Current understanding of litterfall and fine root dynamics in temperate forests is limited, even though these are the major contributors to carbon and nutrient cycling in the ecosystems. In this study, we investigated litterfall and fine root biomass and production in five deciduous and four coniferous forests at the Gwangneung Experimental Forest in Korea. We used ingrowth cores to measure fin...
متن کاملFine root morphological adaptations in Scots pine, Norway spruce and silver birch along a latitudinal gradient in boreal forests.
Variability in short root morphology of the three main tree species of Europe's boreal forest (Norway spruce (Picea abies L. Karst.), Scots pine (Pinus sylvestris L.) and silver birch (Betula pendula Roth)) was investigated in four stands along a latitudinal gradient from northern Finland to southern Estonia. Silver birch and Scots pine were present in three stands and Norway spruce was present...
