1. CHARACTERIZATION OF GEOSPATIAL, MORPHOMETRIC, AND ENVIRONMENTAL DYNAMICS OF THE MARIANA MICROBASIN IN ALTA FLORESTA-MT, BRAZIL
ABSTRACT River basin environmental diagnosis and monitoring are fundamental for water resource use and conservation plans, as these systems integrate different landscape elements and may undergo impacts and changes of different levels and scales. In this context, this work aimed to characterize the geospatial, morphometric, and environmental dynamics in the

2. Prediction of diametric and dynamic structures in a semiarid forest (Caatinga) area submitted to Forest Management, Brazil
ABSTRACT Dynamics studies associated with prognosis can support planning actions for the conservation and sustainable use of forest resources. Therefore, the objective of this study was to evaluate the dynamics and predict the diameter structure using the Markov chain model for an area of caatinga forest submitted to different management practices. The study

4. Future uncertainties for the distribution and conservation of Paubrasilia echinata under climate change
ABSTRACT Paubrasilia echinata is a widely cultivated endangered tree species with small populations restricted to a narrow strip of habitats along the Brazilian coast. The potential impacts of climate change on the distribution of P. echinata have yet to be investigated, and so it remains unknown whether protected areas will ensure the persistence of the spe

5. Aquatic vascular plants of South Brazil: checklist and a comparative floristic approach
ABSTRACT Aquatic ecosystems support species diversity, and knowledge of plant communities is essential for wetland conservation programs. This study provides a checklist of aquatic vascular plants of South Brazil and establishes their floristic affinities with bordering South America phytogeographical domains. The checklist was based on 52 sources, including

6. Grassland vegetation sampling - a practical guide for sampling and data analysis
ABSTRACT Grassland and savanna ecosystems are the original vegetation types of more than 30% of the Brazilian territory, but conservation and training of future professionals has largely focused on forests. In fact, no standard protocols exist for sampling grassland vegetation for environmental planning or licensing. Neglecting non-forest ecosystems may have

7. Modeling of the Rainfall and R-Factor for Tocantins State, Brazil
ABSTRACT The state of Tocantins is inserted in the new Brazilian agricultural frontier and has shown enormous potential for expansion of the agricultural lands. However, there is a lack of more elaborate scientific information for better planning and guide agricultural activities, especially regarding the soil and water conservation. Tocantins has a relevant

8. Estimates of soil losses by the erosion potential method in tropical latosols
RESUMO A erosão hídrica é um dos principais problemas enfrentados na cafeicultura, pois promove a degradação ambiental e a diminuição da produção agrícola. As estimativas da erosão auxiliam no planejamento de práticas e sistemas de manejo conservacionistas e permitem aferir as taxas de perdas do solo. Assim, o objetivo do trabalho foi estimar a p

9. Avaliação dos conflitos no uso da terra na bacia hidrográfica do ribeirão Lamarão, Distrito Federal
Resumo A falta de estudos e a constante degradação das Áreas de Preservação Permanentes (APPs) têm representado um dos maiores entraves para o planejamento de ações conservacionistas, além de favorecer o uso de estratégias inadequadas de manejo das bacias hidrográficas. Dessa forma, este estudo teve como objetivo, delimitar de maneira automática

10. Land use drives change in amazonian tree species
Abstract: The Amazonian rainforest has been subjected to exceptionally high rates of land use change (LUC), primarily for pasture. We present here an analysis of the impact of LUC on trees from studies made in Pará state. LUC results in drastic declines in native species richness, changes species composition and impacts community resilience and ecosystem se

11. Old tools as new support for on farm conservation of different types of maize
ABSTRACT: A germplasm collection should represent the diversity of the target species and the gene pools associated with it. However, it is critical to establish collection plans which ensure such representativeness. At times it is difficult to identify the best strategy for collecting domesticated species that are conserved in situ/on farm, since, in genera

12. Mapping Forest Landscape Multifunctionality Using Multicriteria Spatial Analysis
ABSTRACT This paper presents a GIS methodological approach for mapping forest landscape multifunctionality. The aims of the present study were: (1) to integrate and prioritize production and protection functions by multicriteria spatial analysis using the Analytic Hierarchy Process (AHP); and (2) to produce a multifunctionality map (e.g., production, protect
