1. INFLUENCE OF SOIL TEXTURE, CLIMATE AND VEGETATION COVER ON SECONDARY SOIL SALINIZATION IN PAMPAS PLAINS, SOUTH AMERICA
ABSTRACT Land-use change from herbaceous to woody cover -or vice versa- largely affects water fluxes, which in turn can mobilize existing salts dissolved in the soil, and thereby negatively affect soil and/or water quality and site productivity. Secondary salinization was observed after afforestation at the Northern and Eastern subregions of the Río de la P

3. WOOD QUALITY OF Pinus patula Schltdl & Cham FOR THE PULP PRODUCTION
RESUMO O setor de polpa celulósica de fibra longa tem como base de suprimento as madeiras de Pinus taeda e P. elliottii e compete por essa matéria-prima com outros setores madeireiros. O estudo objetivou avaliar a qualidade da madeira de Pinus patula para a produção de polpa e papel. Árvores com 14 anos foram obtidas de um plantio localizado em Ponte Al

4. Effect of Leaf Quality on Herbivory of Three Atlantic Forest Species
ABSTRACT The present study evaluated the relationship between herbivory and leaf quality of three abundant tree species (Cupania oblongifolia Mart., Siparuna guianensis Aubl. and Xylopia sericea St. Hill.) in the understory of a eucalyptus plantation and an adjacent Atlantic Rainforest fragment. Herbivory differed among species, since X. sericea was less att

5. Red-Yellow Latosol Penetration Resistance Under Different Subsoiling Depths
ABSTRACT The objective of this work was to evaluate the penetration resistance (PR) of a red-yellow latosol submitted to two subsoiling depths for implanting a forest plantation. The subsoiling was evaluated at 40 cm (S-40) and 50 cm (S-50) of depth by determining the soil moisture and soil density, while soil PR was evaluated before and after subsoiling at

6. Distribuição do diâmetro de copa e diâmetro quadrático de Araucaria angustifolia e Pinus taeda
Resumo As funções de densidade de probabilidade têm várias aplicações florestais, entre as quais o tratamento de dados biométricos e uso em modelagem. O objetivo deste estudo foi verificar qual função densidade de probabilidade melhor se ajusta ao diâmetro de copa (dcopa) e ao diâmetro quadrático (dq), e também analisar o efeito dessas variávei

7. Dispersão e impacto de Pinus elliottii Engelm. var. elliottii em área ripária na Floresta Nacional de Capão Bonito -SP
Resumo Conduzido em uma área ripária da unidade de conservação denominada Floresta Nacional de Capão Bonito - SP, este estudo avaliou, em diferentes classes de distância da plantação de Pinus elliottii var. elliottii (pinus): 1) a densidade de vegetação nativa, pinus com cone e pinus sem cone; 2) a área basal de vegetação nativa e pinus com cone

8. Thinning regimes and initial spacing for Eucalyptus plantations in Brazil
ABSTRACT This study focuses on the effects of different thinning regimes on clonal Eucalyptus plantations growth. Four different trials, planted in 1999 and located in Bahia and Espírito Santo States, were used. Aside from thinning, initial planting density, and post thinning fertilization application were also evaluated. Before canopy closure, and therefor

9. Assessing biomass based on canopy height profiles using airborne laser scanning data in eucalypt plantations
This study aimed to map the stem biomass of an even-aged eucalyptus plantation in southeastern Brazil based on canopy height profile (CHPs) statistics using wall-to-wall discrete return airborne laser scanning (ALS), and compare the results with alternative maps generated by ordinary kriging interpolation from field-derived measurements. The assessment of st

10. Efecto del raleo sobre el crecimiento y la densidad de la madera de Pinus taeda implantado en Misiones, Argentina
The greatest increase in growth of the plantation may change the physical properties of wood, and therefore may decrease the wood quality for industry. The current paper aimed to evaluate the effect of thinning treatments on growth and wood density of Pinus taedaplanted in Misiones, Argentina (25º 59' S - 54º24' W). The plantation was established in 1985 w

11. Mudanças nos uso e preços de terras do Estado de São Paulo - período de 1995 a 2010 / Changes in land use and farmland prices in São Paulo State: from 1995 to 2010
This work has examined major changes in land occupation in different regions of São Paulo State to determine major vectors of the observed changes in farmland prices, between 1995 and 2010. This period encompasses both the period of retraction and deregulation of the sugarcane sector, after the extinction of Proálcool program, and the new stage of investme

12. Anatomia ecológica e dendrologia de Eugenia sonderiana O. Berg e Eucalyptus saligna sm. na Serra do Cipó MG
Studies of the wood are valuable for many areas of botany, such as systematic and anatomy, being this last one, the focus of this work. The wood is able to record the environmental variations expressed through the cambium activity, allowing the retrievement of climate data of earlier times. Individuals from a plantation of Eucalyptus saligna located in the P
