1. PLANT RICHNESS AND LIFE FORM DIVERSITY ALONG VEGETATION AND FOREST USE GRADIENTS IN NORTHWESTERN PATAGONIA OF ARGENTINA
ABSTRACT The imbalace between the increase in the demand and the decrease in the supply of products from natural forests, partly explains the on-going development of exotic tree plantations. In northwestern Patagonia of Argentina, Pinus ponderosa (Pinaceae) afforestation plays a key role in ameliorate degraded soils, but may also reduce biodiversity. The eco

2. Growth, Biomass and Carbon Stocks in Forest Cover Planted in an Area of Bauxite Mining in Rehabilitation
ABSTRACT Forest cover in areas degraded by mining is an alternative way of mitigating CO2 concentrations in the atmosphere by fixing C in tree biomass. This study evaluated the growth and C stocks of forest cover in an area of bauxite mining with four sources of fertilizer. Height (Ht), diameter at ground level (DGL), and diameter at breast height (DBH) were

3. Intercropping Acacia mangium stimulates AMF colonization and soil phosphatase activity in Eucalyptus grandis
ABSTRACT: Arbuscular mycorrhizal fungi (AMF) are very important to plant nutrition, mostly in terms of acquisition of P and micronutrients. While Acacia mangium is closely associated with AMF throughout the whole cycle, Eucalyptus grandis presents this symbiosis primarily at the seedling stage. The aim of this study was to evaluate the dynamics of AMF in the

4. HEIGHT-DIAMETER MODELS FOR Eucalyptus sp. PLANTATIONS IN BRAZIL
ABSTRACT The use of height-diameter models have important applications in the management of eucalyptus plantations. The aim of this paper is to provide adequate height models based on the diameter and stand variables that could be easily used and applied to plantation’s management. The data was based on tests located in Espírito Santo and Bahia. A total o

5. Carbon and nutrient stocks of three Fabaceae trees used for forest restoration and subjected to fertilization in Amazonia
ABSTRACT Amazonia is crucial to global carbon cycle. Deforestation continues to be one of the main causes of the release of C into the atmosphere, but forest restoration plantations can reverse this scenario. However, there is still diffuse information about the C and nutrient stocks in the vegetation biomass. We investigated the carbon and nutrient stocks o

6. Land Use and Environmental Zoning of Mixed Ombrophilous Forests for Sustainable Use (Irati National Forest, Brazil Southern Region)
ABSTRACT An environmental zoning proposal due to the demand to develop strategies to ensure biodiversity scenarios for the remaining mixed ombrophilous forests was carried out for the Irati National Forest, a legally protected area for sustainable use located in southern Brazil. To identify land use and cover, Ikonos PSM images dated from December 2004, base

7. Análisis de suelo y foliar en guanábano (Annonamuricata L.) en blanca espuma municipio de Alto Lucero, Veracruz
This study was conducted in a seven years old plantation. Soil and foliar analyzes were performed to determine the physical and chemical characteristics of the soil and the nutrient status of the tree for two climatic seasons (dry and wet). In each of these eight samples were obtained from soil at a depth of 0 to 30 cm, which were mixed to obtain two compoun

8. Biomass production and nitrogen cycling in mixed plantation with Eucalyptus genotypes and Acacia mangium / Produção de biomassa aérea e ciclagem de nitrogênio em consórcio de genótipos de Eucalyptus com Acacia mangium
As plantações de eucalipto ocupam 20 milhões de hectares em solos altamente intemperizados. Plantações consorciadas de eucalipto com acácia têm potencial de melhorar a produtividade do povoamento, em relação às respectivas plantações homogêneas, através do efeito facilitador da fixação biológica de N pelas árvores de acácia. O objetivo foi

9. Efeito das espécies na decomposição da serapilheira e na transferência de N entre folhas em plantios mistos de Eucalyptus grandis e Acacia mangium / Species effects on litter decomposition and N transfer between leaves in mixed plantation of Eucalyptus grandis and Acacia mangium
As espécies fixadoras de nitrogênio (N) são utilizadas junto às plantações florestais com o objetivo de incremento de N. Entretanto quando essas espécies são inseridas à monocultura acorre interferência na formação da serapilheira e, consequentemente, a ciclagem de nutrientes do sistema. O estudo foi desenvolvido em plantios puros e mistos de Euc

10. Tolerance of Anadenanthera peregrina to Eucalyptus camaldulensis and Eucalyptus grandis essential oil as condition for mixed plantation
With the purpose of selecting the species of woody Caatinga for mixed plantations with Eucalyptus spp., the allelophatic effects of E. camaldulensis and E. grandis essential oil were studied on the growth activities of Anadenanthera peregrina. The plants were closed in glass chambers in the presence of volatile oil of E. camaldulensis or E. grandis at the co

11. Agendamento otimizado das atividades de colheita de madeira em plantios de eucaliptos sob restrições operacionais, espaciais e de risco climático / Optimized harvest scheduling in eucalyptus plantations under operational, spatial and climatic risk constraints
Sustainability concerns in forest-based industries, as related to environmental, social and economic aspects, have been highlighted with crescent realism. Therefore, forest management plans must consider a greater level of details when analyzing and understanding the interaction among these aspects to prevent possible future impacts. At the tactical and oper

12. Bioindicadores de qualidade de solo em diferentes ecossistemas
Changes due to soil management and cultivated plant species may influence carbon, nitrogen and phosphorus cycling. Cycling depends on the integration of physical, chemical and mainly microbiological processes. This work assessed some microbial activity and processes related to carbon, nitrogen and phosphorus cycles in soil from six ecosystems in Guarapuava,
