Litterfall contributes to the development of forest soils, since it undergoes a decomposition process that generates release nutrients ontothe soil. Therefore, objective this study was evaluate annual litterfall production, return (Ca, Mg, K and P) thenutrient use efficiency (NUE) in three ecosystems northeastern Mexico. quantified on monthly basis from january todecember 2020 at sites: Site 1 ...

Degraded and drained peat swamp forests (PSFs) are major sources of carbon emissions in the forestry sector. Rewetting interventions aim to reduce loss enhance stock. However, studies rewetting tropical PSFs still limited. This study examined effect on dynamics at a rewetted site an undrained site. We measured aboveground (AGC), belowground (BGC), litterfall, heterotrophic components soil respi...

Litter decomposition makes possible the nutrient cycling and is a link between vegetation soil, vital for healthy forest ecosystem. Although several studies on litter have been carried out in different regions of Brazil, there are few transitional zones Cerrado Caatinga, particularly state Piauí. Therefore, objective this work was to evaluate litterfall production, composition rate tropical dry...

Loss of foundation tree species rapidly alters ecological processes in forested ecosystems. Tsuga canadensis, an hypothesized foundation species of eastern North American forests, is declining throughout much of its range due to infestation by the nonnative insect Adelges tsugae and by removal through pre-emptive salvage logging. In replicate 0.81-ha plots, T. canadensis was cut and removed, or...

Tree growth, biomass productivity, litterfall mass and nutrient content, changes in soil chemical properties and understory forest succession were evaluated over a 8.5-year period in singleand mixed-species (50 : 50) plantations of two N2-®xing species, Casuarina equisetifolia and Leucaena leucocephala, and a non-®xing species, Eucalyptus robusta. At the optimal harvest age for maximum biomass ...

Plants and microbes are the primary drivers in affecting formation accrual of soil organic carbon (SOC) for natural ecosystems. However, experimental evidence elucidating their underlying mechanisms SOC accumulation remains elusive. Here, we quantified plant microbial contributions to successional subtropical forests by measuring leaf-, root-, biomarkers, root leaf litter inputs, C decompositio...

In most soils of the humid tropics, kaolinitic topsoil horizons overlie more gibbsitic horizons. This arrangement cannot be produced simply by leaching. Quantitative measurement of the turnover of chemical elements in the litterfall in an Amazonian ecosystem indicates that the forest cycles a significant amount of elements, particularly silicon. As a result, fluids that percolate through topsoi...
