Abstract The priming effect (PE) is a key mechanism contributing to the carbon balance of soil ecosystem. Almost 100 years research since its discovery in 1926 have led rich body scientific publications identify drivers and mechanisms involved. A few review articles summarised acquired knowledge; last major one was published 2010. Since then, knowledge on microbial communities involved PE + C sequestration has been considerably renewed. This article reviews current state what extent new...
Wood production represents a large but variable fraction of gross primary (GPP) in highly productive Eucalyptus plantations. Assessing patterns carbon (C) partitioning (C flux as GPP) between above- and belowground components is essential to understand mechanisms driving the C budget these Better knowledge fluxes woody non-woody tissues response site characteristics resource availability could provide opportunities increase forest productivity. Our study aimed at investigating how allocation...
The leaf area index (LAI) is a key characteristic of forest ecosystems. Estimations LAI from satellite images generally rely on spectral vegetation indices (SVIs) or radiative transfer model (RTM) inversions. We have developed new and precise method suitable for practical application, consisting building species-specific SVI that best-suited to both sensor characteristics. Such an requires calibration large number representative conditions. two-step approach: (1) estimation subset data...
Root respiration is an important component of the carbon balance a forest ecosystem. We measured CO2 efflux excised fine roots and intact coarse in 3-, 4- 13-year-old Eucalyptus stands region Pointe-Noire, Republic Congo. A transportable adaptable closed chamber gas exchange system directly from 0.5 to 32 mm diameter. Fluxes were corrected for measurement leaks normalized reference temperature 30 degrees C. Mean root rates at varied between 8.5 10.8 micromol kg(-1) s(-1) depending on stand....
Abstract Earthworms are key organisms in terrestrial ecosystems. They found globally and provide significant ecological functions ecosystem services, so their conservation should be a priority. Yet little is known about the large‐scale impacts of global change on earthworm diversity, species distribution, assemblage structure. More importantly, there no comprehensive data changes over long periods time. In 1960s, Marcel Bouché conducted study by sampling assemblages 1399 locations mainland...
• Root respiration at the level of a forest stand, an important component ecosystem carbon balance, has been estimated in past using various methods, most them being indirect and relying on soil measurements. On 3-yr-old Eucalyptus stand Congo-Brazzaville, method involving upscaling direct measurements made roots situ, was compared with independent approach conducted control trenched plots (i.e. without living roots). The first estimation based knowledge root-diameter distribution...
Research conducted on biomass for Ulcos (“Ultra- Low CO2 Steelmaking” European Integrated Project) has progressively focused charcoal supply from tropical eucalyptus plantations. The sustainability of such plantations is being investigated the viewpoint their carbon, water and nutrient budgets: they must all be neutral or positive. Field research producing results at tree stand level in several sites Congo Brazil, while a spatial model developed to identify conditions neutrality scale forest...
