13. WATER AND LIGHT STRESSES DRIVE ACCLIMATION DURING THE ESTABLISHMENT OF A TIMBER TREE UNDER DIFFERENT INTENSITIES OF RAINFOREST CANOPY COVERAGE
ABSTRACT The loss of structure, diversity and functions in the rainforests makes it necessary to develop active strategies to restore their economic and ecological values. Planting selected species can help to catalyze ecosystem restoration. The capacity of the plants to survive and grow in the rainforests, where the canopy coverage changes stochastically, i

14. Forest Restoration Evaluation Through Indicators in Areas of Bauxite Mining
ABSTRACT The state of Pará ranks second in Brazilian mineral production, where bauxite accounts for 84% of total mineral extraction, with negative impacts on the environment as a result. The determination of objectives and targets using environmental indicators as a tool to evaluate forest restoration processes is essential in the recovery of these exploite

15. Restoration Strategies in an Area Invaded by Pteridium aquilinum (L.) Kuhn
ABSTRACT Pteridium aquilinum is an invasive species that stands out for its aggressiveness, invading pastures, agricultural areas and forests. In order to improve this situation, several techniques have been tested, although not common to tropical climate areas. Thus, the objective of this study was to evaluate the survival of eleven tree species according t

16. Benchmark: Biomass Production in Eucalyptus Plantations as a Consequence of Fertilization
ABSTRACT The objective of this work was to evaluate the effects of fertilization, spatial arrangement and age on the biomass production in eucalyptus. The experiment was set up in a randomized block design with four replicates. Overall, 15 fertilizations adopted by forest companies in plots were evaluated, and two arrangements, 3.0 x 3.0 m and 6.0 x 1.5 m,

17. Postural Discomfort in Manual Operations of Forest Planting
ABSTRACT This study evaluated the postural discomfort and health risks of workers in manual forest plantation operations of a company located in the region of Campos Gerais, Paraná State. Data was collected through interviews, using the postural diagram proposed by Corlett, in a sample of 226 workers from manual planting, fertilization and herbicide applic

18. 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

19. Survival of Saplings in Recovery of Riparian Vegetation of Pandeiros River (MG)
ABSTRACT This study monitored the survival of saplings planted according to different recovery models in a riparian forest of the Pandeiros river (Januária, MG). The models consisted of planting the saplings in lines of 2 or 4 m with presence (T2S and T4S, respectively) or absence of direct seeding (T2 and T4, respectively). We planted 16,259 saplings of 17

20. Fungal Community Structure as an Indicator of Soil Agricultural Management Effects in the Cerrado
ABSTRACT Forest-to-agriculture conversion and soil management practices for soybean cropping are frequently performed in the Cerrado (Brazilian tropical savanna). However, the effects of these practices on the soil microbial communities are still unknown. We evaluated and compared the fungal community structure in soil from soybean cropland with soil under n

21. Survival and growth of tree seedlings as a function of seed size in a gallery forest under restoration
ABSTRACT Seed size is commonly related to higher rates of emergence and survival, and biomass of seedlings when introduced by direct seeding. However, few studies have evaluated whether this relationship persists when species are reintroduced as seedlings or if this effect persists after seed reserves decline. This study evaluated the effect of seed size (ma

22. MODELACIÓN DEL EFECTO DE LA PODA Y RALEO SOBRE LAS DEFORMACIONES RESIDUALES LONGITUDINALES EN Eucalyptus globulus Labill.
ABSTRACT A 12-year-old Eucalyptus globulus plantation forest was studied with the aim of assessing and modeling the effect of both pruning and thinning activities on the growth strain. The stand is located in the Andean foothills of Bío Bío region in Chile. Two forest management activities were carried out after 2 and half years from planting, and were eva

23. Soil attributes under different crop management systems in an Amazon Oxisols
AbstractSoil biological properties have a high potential for use in assessing the impacts of crop systems. The objective of this study is to evaluate the effects of cropping systems on the biological attributes of an oxisol in the Amazonian state of Pará. The treatments consisted of approximately 20-year-old secondary vegetation, recovered pasture, no-tilla
