25. Reforestation of a Degraded Area with Eucalyptus and Sesbania: Microbial Activity and Chemical Soil Properties
ABSTRACT Mining activities generally affect soil quality, degrading it and creating the need for consistent environmental recovery efforts. This study evaluates the influence of monospecific and mixed stands of Sesbania virgata (S) and Eucalyptus camaldulensis (E) on the chemical properties and microbial activity of the soil in a degraded area by clay extrac

26. Hearing Profile of Brazilian Forestry Workers' Noise Exposure
Introduction Researchers studying the hearing health of forestry workers have revealed the presence of a noise-induced hearing loss (NIHL) in this population and have concluded that the vibration of the equipment, the carbon monoxide released by motors, and pesticides might also contribute to NIHL.

28. Eucalyptus grandis Hill ex Maiden inoculated with Pisolithus microcarpus (UFSC-Pt116) in land subject to the sandy process in southern Brazil
Eucalypts is one of the main species used for commercial reforestation in the state of Rio Grande do Sul, Brazil. This study aimed to evaluate the survival and early growth of eucalyptus trees in an area subject to sandy process after three years of growth. The Eucalyptus grandis seedlings were grown in a greenhouse, innoculated or not with the isolated ecto

29. Does crotalaria (Crotalaria breviflora) or pumpkin (Cucurbita moschata) inter-row cultivation in restoration plantings control invasive grasses?
Alternative methods to control invasive fodder grasses are necessary to reduce the use of herbicides in forest restoration, which has been carried out primarily in riparian zones. We sought to investigate if inter-row cultivation of crotalaria (Crotalaria breviflora DC) or pumpkin (Cucurbita moschata Duschene ex. Poir) with native tree species is an efficien

30. Soil health: looking for suitable indicators. What should be considered to assess the effects of use and management on soil health?
Soil Health refers to the ecological equilibrium and the functionality of a soil and its capacity to maintain a well balanced ecosystem with high biodiversity above and below surface, and productivity. To understand and use soil health as a tool for sustainability, physical, chemical, and biological properties must be employed to verify which respond to the

31. Strength and stiffness of thermally rectified eucalyptus wood under compression
The aim of this work was the evaluation of the thermal-rectification process of reforestation wood Corymbia citriodora Hook by measuring of mechanical properties under compression parallel to the grain and also determining of chemical composition. The tested samples were thermally treated in a furnace with nitrogen-atmosphere at heating rate of 0.033 ºC.min

32. 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

33. Influência do desenvolvimento florestal sobre a comunidade edáfico-epígea de Arthropoda e a mirmecofauna: bases para a bioindicação do processo sucessional na restauração ecológica / The influence of forest development on edaphic and epigeic Arthropod communities and ant fauna: bases for bioindicantion of successional process in ecological restoration
A restauração ecológica visa o estabelecimento de ecossistemas semelhantes aos que originalmente ocupavam uma determinada área que foi degradada. Todavia, os resultados dos esforços envolvidos na restauração e no retorno dos processos ecológicos naturais são difíceis de serem medidos, pois faltam métodos apropriados. Os bioindicadores são ferrame

34. Efeitos da espacialização da cobertura florestal e da profundidade dos solos na produção de água de uma bacia hidrográfica / Effects of the spatial distribution of forest cover and the soil depth in water yield of a watershed
Several works related to the theme of water production are being made, having in common the association of forest cover with runoff in watersheds. However, no studies were found where the places where this land cover has optimum effect, because it is dependent on climatic and physiographic conditions of each watershed. The objective of this study is to evalu

35. Sistemas agroflorestais na recuperação de áreas de preservação permanente / Agroforestry systems in the restoration of permanent preservation areas
O presente trabalho teve como objetivo promover uma avaliação da utilização de modelos alternativos aos modelos convencionais de reflorestamento para a recuperação de áreas degradadas (AD) em áreas de preservação permanente (APP). Foram analisados o potencial efetivo de recuperação em APP por meio do uso de indicadores de sustentabilidade aplicad

36. Estrutura da paisagem e regeneração natural em reflorestamentos com espécies nativas da Mata Atlântica
Hoje no Brasil restam somente cerca de 7% da vegetação original do bioma Mata Atlântica. No Paraná esse cenário não é diferente, os remanescentes florestais são pouco e pequenos, restando apenas cerca de 10% da cobertura florestal inicial. Com a elevada fragmentação, a recuperação natural das áreas por meio da sucessão secundária fica dificult
