Above-ground biomass accumulation in Cerradão managed by the mass ratio

چکیده
Background: Forests have a huge potential to mitigate global warming through CO2 accumulation in their living biomass. Thus, understanding the functioning of these ecosystems is crucial for revealing factors that drive biomass accumulation. Functional diversity helps us understand ecosystem services, including Within this context, work aimed investigate role functional woody vegetation Cerradão. Methods: We estimated above-ground (AGB) 50 Cerradão stands Brazil and measured five different traits associated with tree species’ survival growth. For each stand, we calculated community-weighted means (CWMs), based on trait, three metrics. specifically explored relationship between CWMs describing metrics AGB. After that, exponential regressions were adjusted, using variables presented significant correlation as independent AGB dependent variable. Regressions more than one variable fitted way avoided collinearity. Based strongest coefficient (r) lowest Akaike value (AIC), chose best regression explain majority variance Results: Our results showed function determining In particular, bivariate correlations show four CWM two are significantly production, showing estimation variables. However, multiple analyses maximum height only trait it alone provides model fit. Conclusions: The explained by mass ratio theory, services directly related presence abundance species greater (Htmax).

Remote Sensing of Above-Ground Biomass
Accurate measurement and mapping of biomass is a critical component of carbon stock quantification, climate change impact assessment, suitability and location of bio-energy processing plants, assessing fuel for forest fires, and assessing merchandisable timber. While above-ground biomass includes both live and dead plant material, most of the recent research effort on biomass estimation has foc...
متن کاملDetermine the most suitable Allometric equations for Estimating Above-ground Biomass of the Juniperus excelsa
Today, modeling and determination of allometric equations of forest trees, especially Junipers trees, are very important for determination of biological status and carbon storage capacity of forest species. The aim of this study was to determine the most suitable allometric equations for estimating the biomass of leaf, sub branch, main branch, trunk, and biomass of total Juniperus excelsa tr...
متن کاملCost and Utilization of above Ground Biomass in Thinning
Billy Watson and Bryce Stokes ABSTRACT: The cost and utilization were compared for a thinning operation removing the stems as roundwood with a flail chipper operationThe flail chipper operation recovered an additional 4.2 tons of acceptable chips per acre which resulted in a higher return to the site. There was little difference in the cost of acceptable chips delivered to the digester between ...
متن کاملAbove-ground biomass and structure of 260 African tropical forests
We report above-ground biomass (AGB), basal area, stem density and wood mass density estimates from 260 sample plots (mean size: 1.2 ha) in intact closed-canopy tropical forests across 12 African countries. Mean AGB is 395.7 Mg dry mass ha⁻¹ (95% CI: 14.3), substantially higher than Amazonian values, with the Congo Basin and contiguous forest region attaining AGB values (429 Mg ha⁻¹) similar to...
متن کاملAbove- and below-ground biomass relationships across 1534 forested communities.
BACKGROUND AND AIMS Prior work has shown that above- and below-ground dry biomass across individual plants scale in a near isometric manner across phyletically and ecologically diverse species. Allometric theory predicts that a similar isometric scaling relationship should hold true across diverse forest-types, regardless of vegetational composition. METHODS To test this hypothesis, two compe...
