“…Foi possível observar que a espécie de Bajao apresentou menor densidade tanto básica quanto aparente, em relação as demais 0,429 g.cm³ e 0,349g.cm³. Silva et al (2018) estudando as propriedades físicas do carvão vegetal da espécie de Aroeira Myracrodruon urundeuva Allemão relatou densidade aparente superior as espécies do presente estudo 0,590g.cm³ respectivamente. Trugilho et al (2001), avaliando diferentes clones de Eucalyptus para a produção de carvão vegetal, encontraram resultados médios para densidade aparente do carvão variando entre 0,40 e 0,49 g/cm3 .…”

Objetivou – se analisar no trabalho a qualidade química do carvão vegetal, densidade e anatomia da madeira de três espécies florestais oriundas de resíduos de podas urbanas do município de Alta Floresta – MT: Oiti Licania tomentosa; Bajão: Parkia multijugae e Ipê: Handroantthus sp. As amostras foram coletadas em forma de discos, numa carvoaria local da cidade e tiveram suas dimensões diminuídas em laboratório. Os parâmetros tecnológicos da madeira foram determinados seguindo normas estabelecidas na literatura. Foi possível verificar que as espécies apresentaram diferenças estatísticas entre si paras os parâmetros tecnológicos analisados. De modo geral os resíduos de espécies florestais podem ser empregados na forma de produção de carvão vegetal, sendo uma fonte econômica do município.

“…In addition, its potential is associated with its ability to regrow, resist drought, adapt to soil conditions, productivity, and acceptance by animals as food (Câmara et al, 2015;Crawford et al, 2015;Azuara-Morales et al, 2020;Barros et al, 2020;Dueñas et al, 2020). The energy potential of its wood is similar to that of Eucalyptus grandis W. Hill (ex Maiden) (Machado, Andrade, Silva, Sena, & Thode-Filho, 2014), whose calorific capacity is adequate for charcoal production (Silva et al, 2018).…”

Invasive species threaten crops and ecosystems worldwide. Therefore, we sought to understand the relationship between the geographic distribution of species populations and the characteristics of seeds using new techniques such as seed image analysis, multivariate analysis, and machine learning. This study aimed to characterize Leucaena leucocephala (Lam.) de Wit. seeds from spatially dispersed populations using digital images and analyzed their implications for genetic studies. Seed size and shape descriptors were obtained using image analysis of the five populations. Several analyses were performed including descriptive statistics, principal components, Euclidean distance, Mantel correlation test, and supervised machine learning. This image analysis technique proved to be efficient in detecting biometric differences in L. leucocephala seeds from spatially dispersed populations. This method revealed that spatially dispersed L. leucocephala populations had different biometric seed patterns that can be used in studies of population genetic divergence. We observed that it is possible to identify the origin of the seeds from the biometric characters with 80.4% accuracy (Kappa statistic 0.755) when we applied the decision tree algorithm. Digital imaging analysis associated with machine learning is promising for discriminating forest tree populations, supporting management activities, and studying population genetic divergence. This technique contributes to the understanding of genotype-environment interactions and consequently identifies the ability of an invasive species to spread in a new area, making it possible to track and monitor the flow of seeds between populations and other sites.

“…The wood of the mastic tree of the hinterland is known for being noble and having good resistance and durability, in addition to being of high size. Its applications are not limited; however, it is mostly used in construction and carpentry (DA SILVA et al, 2018). Due to its high weight and the characteristics described above, the wood from this species easily resists rot and pest attacks, and is therefore suitable for external constructions (BATISTA et al, 2020b;FARIAS;MELO, 2020).…”

The objective of this article is to present the importance of the Cerrado in the ecological and social cohesion of the country, as it is the second largest biome in Brazil and covers approximately 23% of the country. Its magnitude is so great that it makes it the second largest floristic group in the country. Brazil is a country of extraordinary biodiversity, with a wide variety of organisms present in all biomes, especially the Cerrado, which has been devastated by human actions. The Brazilian Savannah is one of the most strategically important regions in the world, mainly for agriculture, crop irrigation, mining, power generation, and the supply of people and animals. Rich in its biodiversity, it provides several essential ecosystem resources to the planet. The destruction of the Cerrado can lead to the loss of species and ecosystem services, negatively impacting the planet. It is extremely important that measures are taken for the preservation of this biome. The protection and preservation of this valuable biome is in line with some of the Sustainable Development Goals. Goal 2 - Zero Hunger and Sustainable Agriculture, is based on the principle of eradicating hunger, achieving food security and better nutrition through the promotion of sustainable agriculture. The proposal is that this goal can be achieved by 2030. Based on the numerous scientific records that prove the nutritional potential of the fruits of the Cerrado, enabling better nutrition for its consumers, it is necessary to encourage the sustainable cultivation and consumption of its fruits, perpetuation of the native trees of the Cerrado that provide not only nutritional benefits, but environmental, social and economic benefits.
