13. Métodos de avaliação da ciclagem de nutrientes no bioma Cerrado: uma revisão sistemática
Resumo Em sistemas florestais, a forma natural de aporte de nutrientes se dá através da serapilheira, a qual compreende todo material vegetal depositado ao solo. Logo, vista a importância do tema, o presente trabalho objetivou realizar uma revisão sistemática sobre as diferentes metodologias utilizadas na temática da serapilheira e ciclagem de nutrient

14. CHANGES IN THE SOIL STRUCTURE AND ORGANIC MATTER DYNAMICS UNDER DIFFERENT PLANT COVERS
ABSTRACT The soil properties reported in areas with different management provide useful information about the systems’ operation, state of conservation and resilience. In this way, this study evaluated physical properties and organic matter dynamics of soil under different plant covers in seven areas consisting of: five areas under ecological restoration (

15. Goods and Services Associated with a Sandy Coastal Plain in Southeastern Brazil
ABSTRACT The objective of this study was to identify, characterize and map an area for its different types of direct and indirect use of native vegetation of sandy coastal plains (Restinga) at “Praia das Neves”, a district of the municipality of Presidente Kennedy, state of Espírito Santo, Brazil. Data were collected on site using an orthophotomosaic pr

16. Describing and diffusing the ethnobotanical knowledge of Bogotá D.C. (Colombia) through an online tool focused on common names of plants
ABSTRACT Although ethnobotanical knowledge is considered potentially valuable information for several human disciplines, it is currently declining due to a decrease in the transmission of cultural knowledge and the depletion of natural resources. Consequently, focused efforts are required to compile such information and ultimately facilitate its diffusion. B

17. The relationship between plant density and survival to water stress in seedlings of a legume tree
ABSTRACT Competition for soil water is one of the major processes that drive the assembly of plant communities, particularly in regions subjected to long dry seasons. The relationship between plant density and soil water competition has strong, but poorly understood, practical implications for population dynamics, restoration and conservation. We planted see

18. Temporal variation of bacterial population and response to physical and chemical parameters along a petrochemical industry wastewater treatment plant
Abstract: The petrochemical industry has played a considerable role in generation and release of waste in the environment. Activated sludge and facultative lagoons are commonly used for domestic and industrial wastewater treatment due to their low-cost and minimal need for operational requirements. Microorganisms present in wastewater treatment plant (WWTP)

19. Biodegradable oil-based polymeric coatings on urea fertilizer: N release kinetic transformations of urea in soil
ABSTRACT: Polymer coatings are used to control the rate of release of plant available nutrients from fertilizers as well as to reduce nutrient losses such as ammonia (NH3) volatilization. Although the literature presents several examples of materials used to coat urea, little is known about nitrogen (N) release properties such as the mechanism involved and p

20. Etiology, occurrence and epidemiology of a begomovirus disease in passionflower in the southwest of Bahia
ABSTRACT: Severe mosaic symptoms, accompanied by yellow spots, abnormally small leaves, fruit malformation and cracking, reduced plant growth, and high levels of whitefly (Bemisia tabaci MEAM1) infestation were observed in passionflower (Passiflora edulis) orchards in southwestern Bahia, Brazil. The aim of this work was to identify the species of begomovirus

21. Maize Productivity, Mycorrhizal Assessment, Chemical and Microbiological Soil Attributes Influenced by Maize-Forage Grasses Intercropping
Abstract Mycorrhizae are important components of agroecosystems and the diversification of crops stimulates the abundance of arbuscular mycorrhizal fungi and the participation of symbiosis in plant growth. This experiment examined mycorrhizal assessment, chemical and microbiological soil attributes in a maize-forage grasses intercropping compared to a maize-

22. Decomposition and Nutrient Release of Cover Crops in Mango Cultivation in Brazilian Semi-Arid Region
ABSTRACT Knowledge of the decomposition dynamics of aboveground phytomass and its release of nutrients in mixtures of cover crops as well as the impact on the soil tillage system is fundamental for the sustainable management of agroecosystems. This work aimed to evaluate whether soil tillage and the choice of cover crops cultivated in the interrows can be te

23. O vigor da planta altera a densidade de galhas em populações de Baccharis longiattenuata (Asteraceae) sob distintas condições de solo?
Resumo A hipótese do vigor da planta sugere que plantas mais vigorosas suportam maior densidade de galhas. Este estudo avaliou tal hipótese utilizando o sistema ácaro-Baccharis longiattenuata em duas populações de restinga sob condições ambientais distintas. As medidas de vigor incluíram: altura e diâmetro do caule, volume e área da copa, número d

24. Nutrient Cycling in Corymbia citriodora in the State of Rio de Janeiro, Brazil
ABSTRACT The quantification and transfer of nutrient stock among compartments in the forest environment is the key to understanding the nutrient cycling process. The aim of this study was to quantify the nutrient stock and dynamics by litter deposition in a Corymbia citriodora settlement in the Mountainous region of the State of Rio de Janeiro. Different pl
