1. Concentration of Metals in Plant Litter Produced in Regions of Caatinga in Southwest Bahia, Brazil
Plant litter has several functions in a forest ecosystem. Studies about plant litter are of great importance to better understand and conserve ecological environments. The objective of this study was to investigate the concentration of metals (Fe, Co, Ca, Cu, Ni, Mg, Mn and Zn) in Caatinga plant litter in the southwest region of Bahia. Plant litter was colle

2. Growth and yield of soybean cultivated in agroforestry systems
ABSTRACT Agriculture has caused numerous concerns regarding the preservation of natural resources. In this context, agroforestry systems are emerging as a more sustainable alternative. The present study aimed to evaluate growth characteristics, radiation use efficiency, biomass partition, and yield of soybean grown in two agroforestry systems and full sun. A

3. QUANTIFICATION OF CARBON IN FOREST NECROMASS: STATE OF THE ART
ABSTRACT Necromass play a significant ecological function, including the deposition of organic matter, which is essential for carbon cycling in forest ecosystems. Despite the devoted attention to the role of forest necromass into the global carbon cycle, international organizations such as IPCC and FAO have reported the lack of compatible data concerning the

4. Nutrition of tree species in tropical dry forest and rainforest environments
ABSTRACT Knowledge of the nutritional efficiency of species can help revegetation of forest areas, guiding the use of species that best adapt to environmental humidity, altitude and diversity. The objective of this study was to evaluate the nutrient utilization efficiency of N, P, K, Ca and Mg of dominant species in tropical dry forest and rainforest environ

5. Copper Accumulation and Distribution in Two Arboreal Species of the Atlantic Forest
ABSTRACT This study aimed to evaluate the accumulation and distribution of copper (Cu) in the pioneer tree Schinus terebinthifolius R. (aroeira) and non-pioneer tree Eugenia uniflora L. (pitanga) submitted to different concentrations of copper. The plants received 40 mL of Hoagland & Arnon (1950) n. 1 nutrient solution modified with 0.00032, 0.0032, 0.032 an

6. 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

7. Modeling residual biomass from mechanized wood harvesting with data measured by forest harvester
Abstract: The lack of accurate models for estimating residual biomass in wood harvesting operations results in underutilization of this co-product by forestry companies. Due to the lack of this information, forestry operations planning, such as chipping and transport logistics, are influenced, with a consequent increase in costs. Thereby, the aim of this stu

9. Aspectos técnicos da produção de pellets de madeira
Resumo A evolução da política energética dos países desenvolvidos, associada à procura por fontes renováveis como a biomassa florestal, impulsionou, desde o início dos anos 2000, o crescimento da produção de pellets de madeira no mundo. O mercado de pellets tornou-se exigente em qualidade e deve lidar com a concorrência de outras fontes de energia

10. Estimativa da oferta de biomassa florestal em povoamentos de Pinus taeda L. após intervenções culturais
Resumo Com a determinação do quanto de biomassa florestal é gerada após as intervenções culturais é possível definir as áreas passíveis de exploração. Com isso, o objetivo do trabalho foi quantificar e estimar a oferta de biomassa de Pinus taeda L. disponível após as intervenções culturais. O experimento foi realizado em reflorestamentos nos

11. CARBON STOCK GROWTH IN A SECONDARY ATLANTIC FOREST
RESUMO As florestas secundárias de Mata Atlântica possuem um papel importante no contexto das mudanças climáticas por atuarem como sumidouro de carbono da atmosfera. Entretanto, essas florestas podem se transformar em fonte de carbono com o aumento da mortalidade de árvores. O conhecimento dessa mudança é possível mediante inventários florestais con

12. Nutrient stock and nutritional efficiency of woody species in dry tropical forest as reforestation indicators
ABSTRACT Efficient forest species can be indicated for reforesting environments, which present nutritional restriction. The objective of this study was to determine the nutrient stock in leaf biomass of the species of greatest importance value (IV) in a tropical dry forest fragment, as well as to evaluate the nutritional efficiency of these species as refore
