| The strategic importance of forest resources, both at the national and global level, as well as the scarcity of reliable qualitative and quantitative information about Brazilian forests are among the motivations that led to the implementation of a new national forest inventory in Brazil (IFN-BR). Beyond traditional field survey through clustered sampling, the IFN-BR incorporates Landscape Sample Units (LSU) as a geospatial component of the inventory. Landscape indicators and indices are generated through the analysis of land use/land cover in the LSUs, which provide information about composition, morphology, mosaic patterns, adjacent habitat similarity, connectivity, fragmentation, and state of riparian zones. In the current study, we describe the... |

| Araucaria Forest is one of most threatened phyto-physiognomies in the Atlantic Forest domain,presenting great ecological-economical importance. Nevertheless, there are still lacks of knowledge concerning growth and dynamic of important species, as Araucaria angustifolia. The objective of this work was to recover the past growth of Araucaria angustifolia, native from Caçador, SC, Brazil, by measuring growth rings and to estimate the average periodic diametric increment. The growth rings were counted and measured, using a stereoscope microscope, in increment cores of 0.5 cm collected from 32 adult trees. The measurements were done with LINTAB measuring table, with 0.01 mm of precision. The samples sizes were irregular, varying from 4.2 to 20.2 cm long. The... |

| A Floresta Ombrófila Mista é considerada uma das principais formações do bioma Mata Atlântica. Apesar de sua importância, existe uma carência de informações sobre a dinâmica de crescimento de espécies dessa tipologia florestal. O presente estudo foi desenvolvido com o objetivo de estimar o crescimento passado de espécies arbóreas de Floresta Ombrófila Mista. Foram realizadas avaliações dendrocronológicas não destrutivas nas espécies Araucaria angustifolia, Ocotea porosa, Ilex paraguariensis, Cedrela fissilis, Ocotea puberula e Ocotea pulchella. O crescimento periódico médio em diâmetro até 2006 foi de aproximadamente 0,5 cm ano-1, para A. angustifolia, C. fissilis, O. porosa e O. pulchella. O. puberula e I. paraguariensis apresentaram crescimento periódico... |

| Remnant forest structure and increment by diameter class play a decisive role in the recovery volume for the next cutting cycle. Tree species in the Amazon Forest do not present a defined pattern of diameter structure, which is discussed here using Cedrela odorata L. as a case study The aim of this study was to identify, by simulation, recovery from logging in a real situation at three timber production sites, and the alternatives that are available to ensure commercial timber volume to a second cut cycle in the Brazilian Amazon. The study is concerned regarding the diametric classes of productive trees to the next cycle, the comparison demonstrates that one of the strategies recovers stock volume more quickly than expected in the cut cycle defined by... |
