2. Logging impact on Amazonian white-sand forests: perspectives from a sustainable development reserve
RESUMO A super-exploração madeireira é uma das principais causas de perda da biodiversidade e extinções locais. Na Amazônia brasileira o uso intensivo focado em poucas espécies tem levado à redução de suas populações e à substituição destas espécies, consideradas “nobres” pelo mercado madeireiro, por espécies “menos nobres” com popul

3. New Contours of the Native Vegetation Protection Law of 2012
ABSTRACT The conservation of natural resources within rural properties is a constitutional obligation. Among the social function criteria required for the exploitation of rural properties, besides the rational use and respect of working conditions, there is a need to ensure environmental protection. The current guidelines regarding the exploration and the en

4. 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

5. Caracterização dos planos de manejo florestal no estado do Piauí
Resumo A lenha é um dos mais importantes produtos florestais da região Nordeste do Brasil, e cada vez mais é necessário que sua exploração seja feita de maneira sustentável. Nesse sentido, o manejo florestal tem sido uma proposta de significativa melhoria das características ambientais dessa atividade. Este trabalho teve como objetivo identificar e a

6. Diversidade e estrutura genética de populações de Podocarpus lambertii Klotzsch ex Endl. na floresta ombrófila mista em Santa Catarina
Resumo Podocarpus lambertii (Podocarpaceae) é conhecido popularmente como pinheiro-bravo. Ocorre em várias formações florestais da Mata Atlântica, principalmente na Floresta Ombrófila Mista. Devido à intensa exploração madeireira sofrida pela espécie, ela está presente na categoria “Quase ameaçada” da Lista Vermelha das Espécies Ameaçadas d

7. Association of Fusarium and Phomopsis with Peroba Rosa Seeds
ABSTRACT Peroba rosa (Aspidosperma polyneuron) is a native forest species endangered due to intense predatory exploitation. The objective of this study was to evaluate the association and fungi transmission in peroba rosa seeds from four regions of Paraná. Germination and vigor were evaluated using the paper roll method. Sanitary analysis consisted of the d

8. Ancient and Current Distributions of Erythrina crista-galli L. (Fabaceae) in South America
ABSTRACT Erythrina crista-galli is a native tree from South America with an important role on pharmaceutical studies. The objective of this study was to model the ancient and current ecological niches distribution of E. crista-galli in South America, contributing to the discussion about species management and conservation. A reduction in the potential area o

9. Genome sequence of Streptomyces gilvigriseus MUSC 26T isolated from mangrove forest
Abstract Streptomycetes remain as one of the important sources for bioactive products. Isolated from the mangrove forest, Streptomyces gilvigriseus MUSC 26T was previously characterised as a novel streptomycete. The high quality draft genome of MUSC 26T contained 5,213,277 bp with G + C content of 73.0%. Through genome mining, several gene clusters associate

10. Drying and reduction in sensitivity to desiccation of seeds of Alibertia edulis: the influence of fruit ripening stage
ABSTRACT The intense environmental degradation in tropical regions suitable for agriculture has decreased native forest populations of plants with important fruits and medicinal properties. Alibertia edulis is a native tree from the Brazilian Cerrado. Knowledge about the effects of drying and storage on the physiological behavior of its seeds may aid in its

11. Growth Stress in Peltophorum dubium and its Correlation with the Growth Variables
ABSTRACT The exploitation of valuable native timber species in forest restoration projects has emerged as a promising strategy to make restoration financially viable. There are few studies regarding the quality of timber from restoration plantations. The aim of this study was to analyze growth stresses by determining the longitudinal residual strain (LRS) a

12. Genome sequence of Streptomyces mangrovisoli MUSC 149T isolated from intertidal sediments
ABSTRACT As the largest genus in Actinobacteria family, Streptomyces species have the ability to synthesize numerous compounds of diverse structures with bioactivities. Streptomyces mangrovisoli MUSC 149T was previously isolated as a novel streptomycete from mangrove forest in east coast of Peninsular Malaysia. The high quality draft genome of MUSC 149T comp
