Abstract Methane is an important greenhouse gas 1 , but the role of trees in methane budget remains uncertain 2 . Although it has been shown that wetland and some upland can emit soil-derived at stem base 3,4 also suggested serve as a net sink for atmospheric 5,6 Here we examine situ woody surface exchange tropical, temperate boreal forest trees. We find uptake on surfaces, particular above about m floor, dominate ecosystem contribution trees, resulting tree sink. Stable carbon isotope...
Dissolved organic matter (DOM) is one of the most complex, dynamic and abundant sources carbon, but its chemical reactivity remains uncertain
Aedes aegypti is adapted to live in close association with human dwellings, where it lays eggs several man-made container types a broad range of size, shape, and material. Biotic abiotic conditions larval habitats determine the abundance body size emerging adult mosquitoes. Here, we estimated predictive potential physicochemical water variables for Culicidae immature Ae. four neighborhoods distinct urban landscapes Rio de Janeiro, Brazil. Domestic holding containers ( N = 240) were inspected...
Anaerobic digestion has been widely applied for waste treatment, renewable energy generation and biofertilizer production. The biogas potential in Brazil is sizable, but the state of Rio de Janeiro largely dependent on fossil fuels, there a lack assessments state. Thus, this study evaluated biomethane, electricity potentials region. Three different scenarios biomass supply were considered four major biowaste streams: sewage sludge; cattle manure; sugarcane processing waste; food waste....
Biogas production via anaerobic digestion is an established and robust technology that produces energy recycles nutrients. Several biotechnological attempts have been applied to this process increase biogas production, including adding nanoparticles, but several discrepancies reported. To elucidate the contradictory results, we performed a literature review followed by meta-analysis evaluate effect of natural nanoparticles sludge. Our results showed can up two orders magnitude. Considering...
The rates of denitrification, dissimilatory nitrate reduction to ammonia (DNRA) an d anammox were evaluated on a typical lake Pantanal wetlands using the isotope pairing method. Denitrification low at all studied sites, ranging from 3,4 34,5µMN 2 m -2 h -1 . O consumption in sediment two three orders magnitude higher, 2630 3880µMO A parallel incubation showed that as 50% added was reduced N through denitrification and activity negligible. From this result we estimated anaerobic is equal...
The study aims to define the potential and technological aspects of digestate treatment for its application as a biofertilizer. Life cycle assessment methodology was used in terms quality management. nutrients, organic carbon, useful microelements allows consideration mineral fertilizer substitute soil improver. valorization requires management control. Based on research focus, successful post-treatment technologies analyzed. Among different commercial options nutrient recovery, most...
ABSTRACT Habitat fragmentation is one of the leading causes edge genesis and its effects. Functional tree traits such as wood density, height, diameter are essential variables from which it possible to infer several ecological processes. This study assessed variability functional trees over two habitats (edge interior) a forest remnant. The hypothesis tested were i) would have lower values at edges than interior, ii) environmental influence differences. was carried out in largest Atlantic...
The Atlantic Forest stores vast amounts of aboveground biomass (AGB), yet it is still a challenge to estimate these stocks. We aimed predict the AGB stock largest biodiversity remnant Serra da Tiririca State Park (Rio de Janeiro, Brazil) by comparing accuracy generalized linear models (GLM) and random forest (RF) models, using data from field plots, remote sensing, environmental variables. plots showed an 371.12 Mg/ha. comparison between modelling methods revealed that GLM more accurate, RF...
The purpose of the paper is to determine environmentally safe and economically feasible technology biofertilizer production from digestate including dewatering process.Methodological basis based on systematic approach determination factors effected distribution nutrients pollutants between liquid solid fractions after separation.We studied modern technologies aimed at reduction its volume, showed their effectiveness.These allow expanding opportunities for commercialization digestate,...
Carbon fixation by chemoautotrophic bacteria represents an autochthonous source of organic matter, and may be particular importance close to redox boundaries. Despite the known sediment potential, quantitative role dark carbon (DCF) in lake sediments are still unknown. We provide here a method measure DCF bacterial production simultaneously stratified cores, using 14 C labeled dissolved inorganic (DI C) 3 H‐leucine incorporation. Beyond total activity, allows measurements processes over...
Abstract. The global nitrous oxide (N2O) budget remains unbalanced. Currently, ~25 % of the N2O emission is ascribed to uncultivated tropical soils, but exact locations and controlling mechanisms are not clear. In this study, we present first detailed study dynamics soil nitrogen pools flux from world's largest wetland Pantanal, South America. At three long-term measurement sites measured porewater pH, NO3–, NH4+ , O2 as well in slurry, situ fluxes CO2. pool inorganic changed (7.1–92 μg...
Two microbial pathways are responsible for most of the methane produced during anaerobic digestion: acetoclastic methanogenesis (AM) and hydrogenotrophic (HM) coupled with syntrophic acetate oxidation (SAO). Identifying dominant methanogenic pathway active in a system provides information necessary to manage optimize productivity, stability, process control, gas quality biogas reactors. In this study, modified method is proposed estimate different systems via short-term parallel incubations...
Endocrine-disrupting compounds (EDCs) are a group of emergent pollutants that affect the endocrine system. EDCs can cause harm to humans and animals unbalance aquatic ecosystem even at low concentrations. Several methods applied remove EDCs, recently, magnetic nanoparticles (MNPs), low-cost magnetically-responsive approach, have been introduced as modern innovative tools for this purpose. Thus, we conducted systematic analysis determine characteristics MNPs required optimize removal in...
