ABSTRACT The use of tropical wood species in reforestation can be an alternative resource to meet the demand from the industrial wood sector. However, this strategy remains very limited, even while tropical forests continue to be deliberately exploited for the selective extraction of native species of highly commercial value. To test the potential of tropical species in reforestation, it is first necessary to evaluate the production and quality of the wood produced. Therefore, this study aimed to evaluate the quality Astronium urundeuva, Astronium fraxinifolium and Terminalia argentea woods, all aged 22 years, from a heterogeneous plantation located in the municipality of Selvíria-MS. From each species, 15 trees were selected. A 10 cm thick disc was removed from the base of each tree. Samples were taken from the discs near the bark region to evaluate the anatomical characteristics and the physical and mechanical properties of the wood. According to the results, it was found that only compressive strength did not differ significantly among the species. Astronium urundeuva presented the highest values for basic density and apparent density, and Terminalia argentea presented the highest values for fiber length, fiber wall thickness and vessel element diameter. The best Pearson correlations were found for basic density and apparent density, both for Astronium fraxinifolium and Astronium urundeuva. The best regression equations obtained were correlations between basic density and apparent density for Astronium fraxinifolium and Astronium urundeuva. The linear model best fits the data for these correlations. The greater growth of Terminalia argentea trees caused lower wood density owing to the lower rate of competition among trees. Based on the results and according to wood strength standards, the three species can be classified in the D40 strength class. According to the obtained results, these can support information to be compared with some species used commercially for structural purposes and other uses. sector However limited value produced Therefore woods 2 years SelvíriaMS.

RESUMO O uso de espécies madeireiras tropicais em reflorestamento pode ser uma alternativa para suprir demanda do setor industrial madeireiro, porém o uso ainda é muito limitado, e as florestas tropicais remanescentes ainda seguem sendo deliberadamente exploradas para extração seletiva de espécies nativas de alto valor comercial. Para testar o potencial das espécies tropicais em reflorestamento é necessário avaliar produção e a qualidade da madeira produzida. Sendo assim, este estudo visa avaliar a qualidade da madeira de Astronium urundeuva, Astronium fraxinifolium e Terminalia argentea aos 22 anos oriundas de um plantio heterogêneo, localizado no município de Selvíria-MS. De cada uma das espécies foram selecionadas 15 árvores. De cada árvore foi retirada um disco de 10 cm de espessura da base. Dos discos foram tomadas amostras nas proximidades da região casca para a avaliação das propriedades da madeira. Para isso foram avaliadas as características anatômicas e propriedades físicas e mecânicas das madeiras. De acordo com os resultados verificou-se que somente a resistência à compressão paralela não se diferenciam significativamente entre as espécies. Astronium urundeuva apresentou os maiores valores para densidade básica e densidade aparente e a Terminalia argentea para comprimento se fibra, espessura da parede da fibra e diâmetro de elemento de vaso. As melhores correlações de Pearson foram encontradas para a densidade básica e densidade aparente, tanto para o Astronium fraxinifolium quanto para Astronium urundeuva. As melhores equações de regressões obtidas foram para a relações entre densidade básica e densidade aparente para o Astronium fraxinifolium e Astronium urundeuva, sendo que o modelo linear foi o que melhor ajustou os dados dessas relações. O maier crescimento das árvores de Terminalia argntea ocasionou uma menor densidade da madeira devido a menor taxa de competição entre as árvores. Com base nos resultados e segundo as normas de resistência da madeira, as três espécies podem ser classificadas na classe de resistência D40. Os resultados obtidos podem subsidiar informações que permitam a comparação com espécies utilizadas comercialmente para fins estruturais e outros usos. madeireiro limitado comercial produzida assim 2 heterogêneo SelvíriaMS.

Abstract We estimated genetic parameters of two Pinus caribaea var. caribaea progeny tests based on growth traits aiming at the identification of the best selection strategy. This study was conducted in two progeny tests located in Selvíria (MS), Brazil. Tests were set up in block design, one with 76 progenies (area 1) and the other with 99 progenies (area 2). Genetic parameters were estimated using the SELEGEN software through REML/BLUP method. To estimate the genetic gain through selection, four selection methods and ten selection intensities were tested. The intensity of selection that maximizes genetic gain and genetic diversity was calculated by the optimization point. Significant variation was observed between and with progeny for all traits in area 2 and only within plots for height in area 1. Higher values of heritability were observed in area 1. Considering the optimization of selection, the best selection method for both areas was the individual. var strategy MS, MS , (MS) Brazil design 7 1 9 2. . 2) REMLBLUP REML BLUP tested point individual (MS

Abstract: Our goal was to determine physical properties and anatomical features in 33-year-old Hevea brasiliensis clones. We cut wood samples from clones LCB510, RRIM600, IAN873, IAN717 and GT1 planted in Selvíria, Mato Grosso do Sul, Brazil. We used standard techniques in wood studies. We found that clones differ in basic density, volumetric shrinkage and anatomical features, with the exception of ray width. Basic density, volumetric shrinkage, fiber length, fiber wall thickness, vessel element length and vessel diameter tended to increase from pith to bark, while vessel frequency propended to decrease. We conclude that wood of the studied clones has potential for industrial use.

Abstract: The use of wood as a bioenergetic source requires knowledge of its technical properties. The rubber tree Hevea brasiliensis has an economic life cycle of 25 to 30 years in Brazil. It is used for extracting rubber and generating residual wood for fuel. Our goal was to characterize the wood quality of 10 clonal progenies as a source of raw material for bioenergy. Ten clonal progenies of 12-year-old Hevea brasiliensis from an experimental planting in Selvíria municipality were evaluated. Three trees per clone were evaluated for individual properties of Higher Heating Value, immediate chemical analysis, chemical composition, fiber dimensions, thermogravimetric analysis of wood under nitrogen atmosphere and Fourier Transform Infrared Spectroscopy analysis. We highlight clone IAC 311 for fuel because it presents elevated Higher Heating Value and fixed carbon and less volatile material. However, the other genetic materials studied also meet the specifications for energy use and can be highly viable given their physical, chemical, energy, and thermal properties.

RESUMO Neste trabalho, foi realizada a previsão da distribuição de M. urundeuva Fr. All., com base na região de ocorrência natural da espécie. Suas coordenadas geográficas foram obtidas nas bases de dados online CRIA e SpecialLinks, a partir de artigos científicos e trabalhos de campo realizados pela Universidade Estadual Paulista (UNESP) em Ilha Solteira, São Paulo, Brasil. M. urundeuva é uma espécie arbórea nativa com grande potencial para uso comercial no Brasil. Para tanto, foi utilizada a modelagem de nicho ecológico, com camadas atuais de variáveis climáticas e camadas preparadas para cenários climáticos futuros, de acordo com o 4º Relatório do Painel Intergovernamental sobre Mudanças Climáticas (AR4/IPCC), utilizando dados do Worldclim no Brasil. Com os programas Open Modeller e ArcGIS, foram gerados mapas para prever sua ocorrência para o período atual e para cenários climáticos futuros, feitos de acordo com as projeções de mudanças climáticas globais. Com a projeção de aumentos de temperatura e precipitação na região onde ocorre a espécie, ela tende a migrar para áreas do Brasil onde o clima é atualmente mais ameno, nas regiões Sul e Sudeste. Devido às mudanças climáticas, a espécie tende a sofrer mudanças na distribuição e tamanho de área até 2080. Foi projetado para a Caatinga e Pantanal, nos dois períodos, um aumento de área, enquanto para o Cerrado, no primeiro período, a área aumentou e para o segundo, diminuiu. Portanto, de acordo com os resultados dos mapas de projeções futuras para as próximas décadas, conclui-se que haverá mudanças na distribuição de M. urundeuva, com redução significativa da área potencial de ocorrência na região.

ABSTRACT In this work, the prediction of the distribution of M. urundeuva Fr. All. was performed based on the region of natural occurrence of the species. Its geographic coordinates were obtained from online databases CRIA and SpecialLinks, from scientific articles and fieldwork carried out by Universidade Estadual Paulista (UNESP) in Ilha Solteira, São Paulo, Brazil. M. urundeuva is a native tree species with great potential for commercial use in Brazil. For this purpose, ecological niche modeling was used, with current layers of climate variables and layers prepared for future climate scenarios, according to the 4th Report of the Intergovernmental Panel on Climate Change (AR4/IPCC), using Worldclim data on Brazil. With the Open Modeller and ArcGIS programs, maps were generated to predict its occurrence for the current period and future climate scenarios, made according to the projections of global climate changes. With the projection of increases in temperature and precipitation in the area where the species occurs, it tends to migrate to areas of Brazil where the climate is currently milder, in the south and southeast regions. Due to climatic changes, the species tends to undergo changes in distribution and area size until 2080. It was projected for Caatinga and Pantanal, in both periods, an increase in area, while for the Cerrado, in the first period, the area increased, and, for the second, it decreased. Therefore, according to the results of the maps of future projections for the next decades, it is concluded that there will be changes in the distribution of M. urundeuva, with a significant reduction of the potential area of occurrence in the region.

Abstract Forest fragmentation in the Cerrado biome exposes the tree species Myracrodruon urundeuva to the risk of extinction. Thus, the objective of the study was to evaluate silvicultural characteristics related to wood quality, based on genetic parameters estimated in two M. urundeuva progenies from natural populations, assessed in Bauru-SP (PBAU) and Selvíria-MS (PSEL), 31 years after planting. The genetic parameters were estimated according to the REML/BLUP (Restricted maximum likelihood/Best Linear Unbiased Prediction) method using a mixed linear model. The progeny tests detected genetic variation. In PSEL, more positive genetic correlations and a greater number of clusters were observed. Based on the heartwood/sapwood ratio, a higher genetic gain was predicted for PBAU, and for the basic wood density, the genetic gain of the populations was approximately the same. Consequently, the areas of the two progeny tests may be used as future seed orchards to ensure wood quality and long-term ex situ conservation.

In this study Ucides cordatus crab shells were utilized as Fe (II) sorbent as material of low cost and simple preparation. Values of pH of standard solution, biosorbent mass, particles size, contact time (t c) and initial concentration of the standard solution were optimized. The best conditions were pH = 2.00, t c = 840 min and Mc = 0.25 g. The kinetic pseudo first-order model displayed the best description of the adsorption process and the equilibrium study showed that the Langmuir model better describes the adsorption of the Fe (II). There is great affinity between the Fe (II) and the biosorbent.
