1. Modeling of tree recruitment by artificial neural networks after wood harvesting in a forest in eastern Amazon rain forest
Resumo A modelagem do recrutamento em florestais tropicais é importante para estudos de sustentabilidade do manejo florestal, por dar subsídio adequado à recuperação do estoque de madeira. O objetivo do trabalho foi estimar o recrutamento após a colheita de madeira, empregando um modelo de rede neural artificial (RNA). A área de estudo está localizad

2. Sexual Systems of Plants in a Brazilian Montane Forest
ABSTRACT In this study, vegetation reproduction has been investigated in order to understand aspects of speciation, structuring and composition of plant communities. Thus, we sought to characterize the frequency of sexual systems from species recorded in seed rain occurring in a tropical rainforest (Atlantic Forest) in Caparaó National Park, Espírito Santo

3. Subsídios para o manejo da invasão biológica de uma palmeira em áreas de Mata Atlântica / Subsidies to ecological management of the biological invasion by a palm tree in Atlantic forest areas
The introduction of alien species in natural habitats resulting in processes of biological invasions is one of the indirect human actions which nowadays threaten global biodiversity. Although bioinvasions usually cause huge negative impacts in the native biota, they are still little studied in the megadiverse tropical environments. The Australian palm tree A

4. Avaliação dos impactos na vegetação após a exploração madeireira em floresta ombrófila densa de terra firme no Município de Caracaraí - RR
Changes on floristic composition and phytosociological and damage we evaluated in forest subjected to reduced-impact logging (RIL) in the municipality of Caracaraí in the state of Roraima. The experiment consisted in the installation of nine permanent plots (1 ha each), under the completely randomized design with three replications and three treatments (T1

5. Efeitos do pisoteio humano experimental sobre a vegetação em fragmentos de Floresta Pluvial Tropical Atlântica, São Paulo, Brasil / Experimental human trampling effect on the vegetation in fragments of the Atlantic Rain Forest, São Paulo, Brazil
The growing flow of visitors at natural areas, with the consequent pressure over natural resources caused an increase on concerns about the produced negative impacts. Recreation Ecology studies the impacts of recreational activities at visited environments, aiming to provide results which are useful for the management of these impacts. The effects of human t

6. Modelagem da dinâmica de crescimento de uma Floresta Ombrófila aerta do estado de Rondônia / Modelling of growth dynamics of tropical rain forest of State of Rondonia, Brazil.
A model of the growth dynamics of forests was developed applying Bertalanffy growth model (BGM) y=a[(1ebt)c] for individual trees. Based on linearized relationship with diameter and height equation LnH=b0+LnD and volume equation V=b0Db1Hb2 mutually compatible equations for diameter, basal area, height and volume were generated, adjusting parameters a and c o

7. Dynamics of gaps / Dinamica de clareiras : comportamento de especies pioneiras e fatores que afetam sua colonização
The Mata Santa Genebra (22°49?45?S 47°06?33?W) is an isolated fragment of the Atlantic Forest. Due to the constant formation of gaps in the interior of the forest it becomes of fundamental importance the knowledge of the dynamics of these gaps for the preservation of the forest. The objectives of this paper were to record and analyze factors which could li

8. Monitoring and characterization of areas submitted to logging in amazonia by change-detection techniques / Monitoramento e caracterização de áreas submetidas à exploração florestal na amazônia por técnicas de detecção de mudanças
Selective logging has been affecting extensive areas of primary forests in Amazonia. This activity, when practiced in a predatory way, causes severe environmental impacts such as erosion and soil compaction, increased carbon emissions, increased forest-fire susceptibility and increased risk of local species extinction. Monitoring logging activity is fundamen

9. Análise quantitativa e qualitativa do crescimento de caixeta - Tabebuia cassinoides (LAM.) DC. - em florestas manejadas, no município de Iguape/SP. / Quantitative and qualitative analysis of the growth caixeta tabebuia cassinoides (lam.) dc. in forest handeled in the municipal district of Iguape/SP.
Caixeta Tabebuia cassinoides (LAM.) DC. is a tree species of swamp forests in the Atlantic Rain Forest. It has been used since the 30s, mainly for clog and pencil production. IBAMA Decree no. 218 prohibited Caixetas explotation in 1989. By its importance for the community and social movement, caixetas management was regulated by the Resolution 11

10. Classificação e monitoramento fenológico foliar da cobertura vegetal na região da floresta Nacional do Tapajós - Pará, utilizando dados multitemporais do sensor "thematic mapper" (TM) do Landsat / Phenology foliar classification and monitoring the vegetation cover in the Tapajós National Forest region Pará State, utilization multitemporal data from Landsat Thematic Mapper (TM) sensor
The relative importance of accuracy in forest cover mapping is given by the necessity to obtain improvement in the elaboration of a management plan of natural resources and in the definition of priority areas for conservation, as well as in landscape analysis. Other aspect that has raised even more interest in the scientific community is concerned to modelin

11. Forests, timber and dwellings : energetic and environmental analysis of wood production and utilisation as a contribution to the challenge of theAmazonian Rain Forest Valuation / Florestas, madeira e habitações : analise energetica e ambiental da produção e uso de madeira como uma contribuição ao desafio da valorização da Floresta Amazonica
This work carries out an energy consumption and CO IND. 2 emissions assessment on the production chain of three supplying systems for timber use in residential buildings: (1) timber obtained from the management of native forest; (2) timber obtained from the predatory extraction of native forest and (3) timber from eucalyptus plantations. The energetic sustai
