Carbon stock assessment and comparison in soybean plantations in Southwest Braz...
Guaraná Araujo, Emmanoella Costa; Pelissari, Allan Libanio; Dalla Corte, Ana Paula; Sanquetta, Carlos RobertoA significant proportion of deforestation in the Amazon rainforest is for the expansion of agriculture and livestock. Several studies have been dedicated to determining the carbon stock in natural forests, however agricultural areas are still poorly researched. This work aimed to quantify the above and belowground carbon stock (CS) in soybean plantations in the State of Rondonia, Southwest region of the Brazili...
Simultaneous estimation as an alternative to young eucalyptus aboveground bioma...
Oliveira, Thiago Wendling Gonçalves de; Rubilar, Rafael; Sanquetta, Carlos Roberto; Dalla Corte, Ana Paula; Behling, AlexandreAccurate forest biomass estimates require the selection of appropriate models of individual trees. Thus, two properties are required in tree biomass modeling: (1) additivity of biomass components and (2) estimator efficiency. This study aimed to develop a system of equations to estimate young eucalyptus aboveground biomass and guarantee additivity and estimator efficiency. Aboveground eucalyptus biomass models ...
Taper functions to describe the stem profile and total bole volume for Pinus ca...
Silva, Fernando da; Dalla Corte, Ana Paula Aula; Sanquetta, Carlos RobertoThe aim of this study was to evaluate the accuracy of taper functions for estimating diameters along the stem according to diameter classes and total volume. Studied was Pinus caribaea var. hondurensis in the Triangulo Mineiro region, state of Minas Gerais. The database consisted of 200 trees measured by the method of Hohenadl with ten sections, randomly chosen based on age and diameter distribution. The ages o...
Biomass expansion factor and root-to-shoot ratio for Pinus spp. in southern Brazil
Dalla Corte, Ana Paula Aula; Silva, Fernando da; Sanquetta, Carlos RobertoBiomass expansion factor (BEF) and root-to-shoot ratio (R) are variables for quantification of carbon in forests. These are considered as constant values in most studies. 70 sample trees were used to BEF and R, and DBH, tree height and age. Dry total biomass, carbon and CO2 equivalent were simulated by using the IPCC default values of FEB and R, corresponding average calculated from data using in this study and...
Biomass expansion factor and root-to-shoot ratio for Pinus in Brazil
Sanquetta, Carlos Roberto; Dalla Corte, Ana Paula Aula; Silva, Fernando daThe Biomass Expansion Factor (BEF) and the Root-to-Shoot Ratio (R) are variables used to quantify carbon stock in forests. They are often considered as constant or species/area specific values in most studies. This study aimed at showing tree size and age dependence upon BEF and R and proposed equations to improve forest biomass and carbon stock. Data from 70 sample Pinus spp. grown in southern Brazil trees in ...
DINÂMICA DO VOLUME, BIOMASSA E CARBONO NA MATA ATLÂNTICA POR FERRAMENTA DE DETE...
Machado, Ayrton; Martins, Ana Paula Marques; Sanquetta, Carlos Roberto; Dalla Corte, Ana Paula; Wojciechowski, Jaime; Machado, Sebastião do AmaralA Mata Atlântica é reconhecida internacionalmente como uma das maiores e mais importantes florestas tropicais do continente sul-americano e além de sua importância para a biodiversidade, esse Bioma exerce importante função no ciclo de carbono. O objetivo deste trabalho foi desenvolver e aplicar uma rotina de detecção de mudanças dos estoques de volume, biomassa e carbono de 2000 a 2015 na Bacia do Rio Iguaçu, E...
Diametric distribution and main species in Miombo, Mopane and Mecrusse ecosyste...
Bila, Jacob Miguel; Sanquetta, Carlos Roberto; Corte, Ana Paula Dalla; de Freitas, Lucas José MazzeiForest resources in Mozambique play an important role in the national economy, not only meeting basic needs of local communities, but also to supply the forestry industry and to export. This work aimed to evaluate the performance of probability density functions in the adjustment of the diametric distribution and phytosociological analysis through the horizontal structure of Miombo, Mopane and Mecrusse ecosyste...
USO DE DADOS LiDAR NA ESTIMATIVA DE VARIÁVEIS BIOFÍSICA NA AMAZÔNIA, SOB DIFERE...
Rex, Franciel Eduardo; Dalla Corte, Ana Paula; Debastiani, Aline Bernarda; Kazama, Verônica Satomi; Sanquetta, Carlos RobertoA Floresta Amazônica é conhecida pela sua diversidade e quantidade de carbono estocado na biomassa acima do solo (do inglês, Above-Ground Biomass-AGB), o que atrai grande interesse em quantificar estes recursos naturais. Devido às dificuldades de mensuração desses dados em campo, o sensoriamento remoto oferece oportunidade na quantificação destes parâmetros (biomassa e carbono), de forma rápida e com custos rel...
IMPACTO DO USO DA TERRA NA EFICIÊNCIA DO SEQUESTRO DE CARBONO NO SUL DA AMAZÔNIA
Kazama, Verônica Satomi; Corte, Ana Paula Dalla; Rex, Franciel Eduardo; Debastiani, Aline Bernarda; Sanquetta, Carlos RobertoEsta pesquisa objetivou analisar a eficiência do carbono sequestrado em diferentes classes de uso e ocupação da terra entre os anos de 1989 a 2016 do município de Lucas do Rio Verde, Mato Grosso, situado na fronteira sul da Amazônia. Foram utilizadas duas imagens orbitais da série Landsat (TM e OLI), ambas do mês de julho. Efetuou-se a seleção do melhor método de classificação do uso e ocupação da terra, testan...
Modeling of the frequency distribution of soil organic carbon of Araucaria Fore...
Barreto, Tauane Garcia; Klein Hentz, Ângela Maria; Netto, Sylvio Péllico; Corte, Ana Paula Dalla; Sanquetta, Carlos RobertoThis work aimed to describe the frequency distribution of soil organic carbon contents under different conditions of Araucaria forest (concentration of araucaria trees, imbuia trees and mixed forest, with record of fire) in Paraná State, Brazil. Fitness quality of probability density functions (normal, Weber, Weibull 3P, log-normal, SB of Johnson and Gamma) were determined, using Kolmogorov Smirnov test. All fu...
