1. CLOROFILA EXTRAÍDA DE RESÍDUO INDUSTRIAL DA ERVA-MATE (Ilex paraguaiensis) UMA POSSIBILIDADE DE ECONOMIA CIRCULAR
Chlorophyll is the most abundant green pigment on the planet, it is unstable and decomposes naturally. Mate-herb is a traditional native plant in the southern region of South America, and its tea is part of the local culture and extractive agriculture. The mate-herb industry generates as a by-product a resinous material rich in chlorophyll whose use is propo

2. Chemical profile and antioxidant activity of geopropolis from Melipona subnitida collected inside and outside the nest
Melipona subnitida (“jandaíra”) is a species of stingless bee endemic to the Caatinga, a dry forest in the northeastern Brazilian semi-arid. Propolis is a product containing beeswax and plant resin. It contains compounds that can be able to prevent health problems by protecting cells against damage by oxidative agents. M. subnitida produces geopropolis,

3. 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

4. Characterization of bacterial endophytes from the roots of native and cultivated Brazil nut trees (Bertholletia excelsa)
RESUMO A castanha-do-brasil é um produto florestal não madeireiro muito importante na região amazônica. A propagação desta árvore ainda representa um desafio, devido ao lento e irregular processo de germinação das sementes. Neste contexto, bactérias promotoras do crescimento vegetal podem facilitar o processo de propagação. O objetivo deste estud

6. Modeling of Soil Losses on a Yellow Argisol Under Planted Forest
ABSTRACT Erosion prediction models are a useful tool for soil use planning and soil conservation. This study aimed to apply the Universal Soil Loss Equation (USLE) in an experimental sub-basin located in the municipality of Teixeira de Freitas, in the southern end of the state of Bahia, Brazil. The following variables were calculated: rainfall erosivity fac

7. Addition of toasted baru nut (Dypteryx alata Vog.) and extruded rice bran to sugar cane candy (“rapadura”)
Abstract Different proportions of sugar cane juice, toasted baru nut and extruded rice bran were used in the formulation of sugar cane candies (“rapaduras”), and the effect on color, hardness and proximate composition determined. The best formulation was selected on the basis of composition, hardness and luminosity, and evaluated for sensory acceptance

8. Genetic diversity and population structure of Vriesea reitzii (Bromeliaceae), a species from the Southern Brazilian Highlands
Abstract The Southern Brazilian Highlands are composed by a mosaic of Mixed Ombrophilous Forest (MOF) and grassland formations, an interesting landscape for the study of population structure. We analyzed the genetic diversity within and among populations of the MOF-endemic bromeliad Vriesea reitzii by genotyping seven nuclear microsatellite loci in 187 indiv
