Greenhouse gas emissions due to land use change in Brazil from 1990 to 2015: co...
Sanquetta, Carlos; Corte, Ana Paula Dalla; Sanquetta, Mateus; Pelissari, Allan; Tomé, MargaridaNet CO2 emissions due to land-use change (LUC) resulting from the conversion of natural forest vegetation in Brazil were analyzed over 25 years (1990-2015). Recognized data sources were studied and emission values were compared. Our analysis included LUC emissions over time, which were stratified by biome. In addition, implications for the fulfillment of commitments assumed by Brazil in the Paris Agreement were...
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...
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...
Effect of the age on them stem form of Araucaria angustifolia in Central-Southe...
Martins, Ana Paula Marques; Machado, Sebastião do Amaral; Figueiredo Filho, Afonso; Corte, Ana Paula Dalla; Gorenstein, Maurício RomeroThe evolution of the stem form of trees in stands of Araucaria angustifolia (Bertol.) Kuntze was studied by means of taper functions and form factors. The data used were obtained by complete stem analysis and by rigorous scaling of standing trees in stands established in central-southern region of Paraná, with a sample of 45 trees. Four taper functions were adjusted for the total data set and for stratified dat...
Growth modeling of Cryptomeria japonica by partial trunk analysis
Coutinho, Vinícius Morais; Corte, Ana Paula Dalla; Sanquetta, Carlos Roberto; Rodrigues, Aurélio Lourenço; Sanquetta, Mateus Niroh InoueThis study aimed to evaluate the growth pattern of Cryptomeria japonica increment (L. F.) D. Don. and to describe the probability distribution in stands stablished at the municipality of Rio Negro, Paraná State. Twenty trees were sampled in a 34 years-old stand, with 3 m x 2 m spacing. Wood disks were taken from each tree at 1.3 m above the ground (DBH) to perform partial stem analysis. Diameter growth series w...
POTENCIAIS CORREDORES ECOLÓGICOS ENTRE AS UNIDADES DE CONSERVAÇÃO DA REGIÃO LES...
Martins, Ana Paula Marques; Debastiani, Aline Bernarda; Gaiad, Natália Peixoto; Corte, Ana Paula Dalla; Sanquetta, Carlos RobertoO objetivo deste trabalho foi indicar rotas potenciais para a implantação de corredores ecológicos visando a interligação das Áreas de Proteção Ambiental (APAs) da região leste da Bacia do Alto Iguaçu. Para tanto, utilizou-se de um Sistema de Informação Geográfica, onde as classes utilizadas foram: perímetro, uso e cobertura da terra, modelo digital do terreno e rede hidrográfica da bacia. Utilizou-se a metodol...
Characterization of the environmental fragility of a urban river basin in the m...
Schiavo, Bruna Nascimento de Vasconcellos; Hentz, Ângela Maria Klein; Corte, Ana Paula Dalla; Sanquetta, Carlos RobertoThe Geoprocessing has been considered a fundamental tool in the definition of intervention policies and environmental management. This work presents a methodological guide of application of Geoprocessing technologies to characterize the environmental fragility of Arroio Cadena sub river basin, inserted in the municipality of Santa Maria, central region of Rio Grande do Sul state. We used the methodology propose...
Precision and relative efficiency of sampling methods in teak
Miranda, Dirceu Lucio Carneiro; Francio, Jonas; Santos, Juliano de Paula; Sanquetta, Carlos Roberto; Corte, Ana Paula DallaThis study aimed to compare three sampling methods: fixed area, Bitterlich, and Prodan, regarding accuracy and relative efficiency to estimate the variables: diameter at 1.30 m above soil level (DBH), number of trees, basal area, and volume. The limit of error established was 10% at probability level of 95%, using 30 plots for each method. Circumference at 1.30 m above soil level was measured, for conversion in...
Organic carbon contents of three tree species in different spacing
Behling, Alexandre; Sanquetta, Carlos Roberto; Caron, Braulio Otomar; Schimidt, Denise; Elli, Elvis Felipe; Corte, Ana Paula DallaThis study aimed to evaluate the content of organic carbon in plant parts (leaves, wood, twigs and bark) of forest species Acacia mearnsii De Wild, Eucalyptus grandis Hill and Mimosa scabrella Benth, under different spacing between trees (2.0 m x 1.0 m, 2.0 m x 1.5 m, 3.0x1.0 m and 3.0 m x 1.5 m), one year after planting. It was also aimed to verify if the conversion factor of 50% can be applied. To determine t...
