Understanding the genetic impacts of forest management practices is crucial for conservation and management of forest genetic resources. Forest management practices based on selective and clear cut systems followed by natural or artificial regeneration can impact population structure and mating patterns, thus gene flow and genetic diversity. Survival and productivity of both tree and non-tree species can be compromised or, possibly, enhanced. The extent of genetic impacts depend on the management system applied, stand structure as well as species' distribution, demography, biological attributes and ecology. The impact of management practices is reviewed and synthesized for temperate, boreal and tropical forests based on experimental and simulation studies. In addition, the effects of genetically improved planting materials and establishment of large scale plantations on natural forests are examined. Recommendations are made for genetically sustainable forest management practices. (Résumé d'auteur

“…The surface in natura of EGP Angelim pedra that presented greater roughness can be explained by its anatomy. According to Ferreira, Gomes and Hopkins (2004) and INPA/CPPF (1991) species of the genus Hymenolobium tend to present coarse texture and reverse grain. This behavior was observed by Thoma, Peri and Lato (2015) when assessing the surface roughness of the woods of the Albanian region (Abies alba, Pinus halepensis, Fagus sylvatica, Juglans regia and Quercus petraea).…”

In the Amazon, the sustainable use of wood is associated with technological research that indicates industrial use. Surface roughness of wood is an important criterion for assessing tool condition, machining performance and product quality. The objective of this study was to evaluate the surface roughness of five Amazonian woods used in the manufacture of EGP (Edge Glued Panels).The woods Angelim pedra, Angelim vermelho, Breu vermelho, Murici and Piãozinho, obtained from managed areas of the Amazon, were used in the manufacture of EGP panels. Surface treatments were performed with 120 and 180 grit sandpaper. Surface ripples (roughness) were measured using a digital roughness meter with needle (n = 180 readings). Physical and mechanical tests were performed on both wood and EGP samples, to verify the possible relationship between these properties and roughness. EGP Piãozinho presented better surface quality, which consists of lower roughness (lower surface wave height), while EGP Angelim pedra presented uneven surfaces. Surface quality was satisfactory when 120 grain sandpaper was applied to most products. The results showed a highly significant effect of roughness such as the physical-mechanical properties. The highlight of the study is the wood and EGP Piãozinho, because in all the tests, it always presented the best performances.

“…The wood of the species collected were, in general, different in color and designs can be grouped into three distinct colors: yellow-grey, brown and red with brindle designs. Several scholars, among them Coradin and Camargo (2002), Ferreira, Gomes and Hopkins (2004) and Zenid (2008) cite that the grouping of species by characteristics such as color and density Knott, with a 5% significance level, was used to determine if there were statistical differences between the averages shown.…”

Despite the large diversity, logging on Brazilian Amazon is restricted to a small number of species. On relating the local biodiversity to the density, region of occurrence and logging of traditional species, we verified the increment of their shortage. One way to minimize this problem is by introducing new species in the market. Based on these considerations, we sought to identify in the field, woods known as matá-matá (Eschweilera Mart. Ex DC.-Lecythidaceae) of high frequency in the Brazilian Amazon. For this, eleven trees were collected for scientific identification, and for anatomical, physical and chemical analyses. During the identification, we verified the presence of six species (Eschweilera amazonica, Eschweilera coriacea, Eschweilera grandiflora, Eschweilera idatimon, Eschweilera ovata and Eschweilera sp.) which may be identified in the forest by their rytidomes and live bark characteristics. By organoleptic properties, we grouped the woods into three groups with distinct colours, which permitted the identification of two species by their characteristics of taste and smell. Macroscopically, all woods seemed similar, while microscopically, the species presented few differences which made their partial separation possible. RESUMO: Apesar da grande diversidade de espécies florestais amazônicas, o corte de árvores é restrito a um pequeno número de espécies. Com relação à densidade da biodiversidade local, à região de ocorrência e ao registro de espécies tradicionais, verificou-se um aumento da escassez dessas espécies. Uma forma de minimizar tal problema é pela introdução de novas espécies no mercado. Considerando-se essa possibilidade, buscou-se identificar no campo espécimes conhecidas por matá-matá (Eschweilera spp.-Lecythidaceae), uma vez que é um gênero muito abundante na Floresta Amazônica. Para isso, amostras de 11 indivíduos foram coletadas para identificação científica e análises anatômicas, físicas e químicas. Esses indivíduos foram classificados em seis espécies: Eschweilera amazonica, Eschweilera coriacea, Eschweilera grandiflora, Eschweilera idatimon, Eschweilera ovata e Eschweilera sp., que podem ser identificadas pelas características de suas cascas. Pelas propriedades organolépticas, tais espécies foram agrupadas em três grupos de coloração distinta, o que permitiu a identificação de duas espécies pelas características de sabor e cheiro. Macroscopicamente, a madeira de todas as espécies parecia semelhante; microscopicamente, as espécies apresentaram poucas diferenças que possibilitaram sua parcial separação.
