Potential litterfall of Scots pine branches in southern Finland
Litter input drives dynamic soil models that are used to understand the flows and stocks of soil carbon. In estimation of above-ground litterfall, much of the uncertainty lies in the turnover rate of branches. The objective of this study was to develop a model for estimating the branch litterfall of Scots pine stands. Here the potential litterfall of branches was modelled as a function of tree ...
متن کاملVariation in foliar nitrogen and aboveground net primary production in young postfire lodgepole pine
Understanding nutrient dynamics of young postfire forests may yield important insights about how stands develop following stand-replacing wildfires. We studied 15-year-old lodgepole pine stands that regenerated naturally following the 1988 Yellowstone fires to address two questions: (1) How do foliar nitrogen (N) concentration and total foliar N vary with lodgepole pine density and aboveground ...
متن کاملFine root biomass and production in Scots pine stands in relation to stand age.
We determined fine root biomass and production of 15-, 35- and 100-year-old Scots pine (Pinus sylvestris L.) stands during three growing seasons. Fine roots were sampled by the soil core method. Mean (+/- SE) annual fine root biomass of Scots pine in the 15-, 35- and 100-year-old stands was 220 +/- 25, 357 +/- 21 and 259 +/- 26 g m(-2), respectively. Fine root biomass of the understory vegetati...
متن کاملSimulation of Aboveground net primary production by using the climatic factors in the Siahpoush and Ganjghah rangelands of Ardabil Province
Aboveground net primary production (ANPP) is one of the crucially characteristics of rangeland ecosystems and it is importance in the cycle of materials and energy in these ecosystems. The aim of present study was investigate the ANPP of life forms (grasses, forbs, and shrubs), and total ANPP; then modeling of life forms and total ANPP by using precipitation and temperature in Siahpoush and Gan...
متن کاملCarbon stocks across a chronosequence of thinned and unmanaged red pine (Pinus resinosa) stands.
Forests function as a major global C sink, and forest management strategies that maximize C stocks offer one possible means of mitigating the impacts of increasing anthropogenic CO2 emissions. We studied the effects of thinning, a common management technique in many forest types, on age-related trends in C stocks using a chronosequence of thinned and unmanaged red pine (Pinus resinosa) stands r...
