13. Efeito do reflorestamento com diferentes espécies sobre os atributos químicos em solo de cerrado.
RESUMO: O objetivo desse trabalho foi avaliar o efeito do reflorestamento com eucalipto (Eucalyptus camaldulensis), carvoeiro (Sclerolobium paniculatum) , pinus (Pinus tecunumanii) e baru (Dipteryx alata) sobre os teores de nutrientes e de carbono orgânico do solo em comparação com uma área sob vegetação de Cerrado. Foram coletadas amostras de solo nas

14. Estoque de carbono nos solos da bacia do Rio Araguari-MG: estimativas, modelagem e cenários
The soils can act as a source or carbon sink to the atmosphere, depending on the climate conditions and, especially, the type of use and management adopted. Taking into consideration the stock/sequestration carbon potential, admittedly, attributed to several land uses, as in planted forests (Pinus and Eucaliptus), and no-till areas, as well as the efficiency

15. 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,

16. Caracterização da estrutura anatômica do lenho, dos anéis de crescimento e dos canais de resina de árvores de Pinus caribaea var. hondurensis Barr. et Golf. / Characterization of the anatomical structure of the wood, the growth rings and the resin ducts in Pinus caribaea var. hondurensis Barr. et Golf.
The research on resin tapping trees with pine species have shown the effect of factors that affect the production and quality of resin, related with the species, genetic variability, growth rate, age, forest management, etc.. The gum-resin extraction practices, the concentration, frequency of application of chemical stimulants, the time of year that panels a

17. Aspectos ecológicos e econômicos do plantio de Pinus elliottii Engelm var. elliottii como facilitadora da restauração de mata ripária em região de Cerrado (Assis, SP, Brasil) / Exotic species in forest restoration: ecological and economical aspects of using Pinus elliottii Engelm var. elliottii as pioneer in Cerrado region, Assis, SP, Brazil
Among the obstacles to the native forests restoration in Brazil we find the high costs of planting high diversity of native trees. Searching for reduction of costs and vegetation recovery acceleration, the use of a fast growing exotic species (Pinus elliottii var. elliottii) as pioneer was tested in a riparian area in the cerrado domain, at Assis municipalit

18. Carbon and nitrogen in the soil under different uses and managements and your modelling by the Century / Carbono e nitrogênio no solo sob diferentes usos e manejos e sua modelagem pelo Century
Every change in the use and management can induce alterations in the C and N stocks of the soil. In this sense, this study was carried out to verify those alterations in the different use and management systems, as well as the capacity of the Century model to simulating those alterations, by comparing the measured stocks with the simulated ones. In Paracatú

19. INFLUENCIAS DE LA DENSIDAD Y PODAS SOBRE LA PRODUCCIÓN DE Pinus taeda L. A LOS 7 AÑOS DE EDAD
ABSTRACT In an experiment with 3 stand densities and 12 prune treatments there were analyzed the effects of stand density, prune and interaction between them on the yield of a Pinus taeda L. plantation. The stand variables analyzed were diameter at breast height (DBH), stem volume, volume per hectare, height, basal area, diameter over stubs (DMSM), Girard fo

20. INDICADORES DE IMPACTO AMBIENTAL DE PLANTACIONES FORESTALES - COMPONENTE VEGETAL
ABSTRACT In order to determine environmental impact, indicators based on vegetation characteristics that would generate the forestry monoculture with the adjacent native forest, 32 sample unit were installed in an area of LIPSIA private enterprise, Esperanza Department, Misiones with those characteristics. The plots of 100 m2 were distributed systematically

21. PRECISION SILVICULTURE IN MONITORING AND CONTROL OF LEAF CUTTING ANTS IN Pinus PLANTATIONS / SILVICULTURA DE PRECISÃO NO MONITORAMENTO E CONTROLE DE FORMIGAS CORTADEIRAS EM PLANTIOS DE Pinus.
A control and monitoring study of leaf-cutting ants was done in Pinus plantation areas from Bosques del Plata company, Argentina. The research was divided into five chapters: Chapter I Species of leaf cutting ants in the Pinus spp. plantation, Corrientes-Argentina: to identify the species in the field plantation 2004; to verify what are the prevailing specie

22. Patch-matrix interactions and bird species conservation in a plantation-dominated landscape in Australia
Conservation of wildlife and key ecological processes in production landscapes are essential for the achievement of ecologically sustainable natural resource use. Thus, investigations of wildlife response to landscape change have become critical. This thesis aims to obtain information useful for the better integration of wildlife conservation and wood produc

23. EVOLUCIÓN DE LAS PRINCIPALES VARIABLES DE ÁRBOLES DE Pinus taeda L. SOMETIDOS A DIFERENTES TRATAMIENTOS SILVICULTURALES EN EL NORDESTE DE LA PROVINCIA DE CORRIENTES, ARGENTINA
ABSTRACT A study was developed in order to examine the relationship between thinning, pruning and increment of trees and stands of Pinus taeda L., as well as to determine models that could predict production and quality of logs. Information on diameter at breath height (dbh), total height (h) and volume (dbh 2 * h) were obtained in a trial established in 1

24. Mamíferos não-voadores do campus "Luiz de Queiroz", Universidade de São Paulo, Piracicaba, Brasil
The remaining portion of the Atlantic Forest within the State of Sao Paulo is highly fragmented and most of the remainders are wrapped up in an essentially agricultural mosaic. This study aims at the local surveying of non-volant mammals, including their distribution and relative abundance within the human-altered environments of campus "Luiz de Queiroz", Un
