1. EVALUATION OF DIVERSITY AND GENETIC STRUCTURE AS STRATEGIES FOR CONSERVATION OF NATURAL POPULATIONS OF Dalbergia nigra (Vell.) Allemão ex Benth.
ABSTRACT: The evaluation of diversity and genetic structure allows us to verify with precision the effect of evolutionary and anthropic processes on species. The objective of this research was to evaluate the divergence and the genetic structure of two natural populations of Dalbergia nigra, using molecular markers Inter Simple Sequence Repeats (ISSR).

2. Brazilian herbaria: an overview
ABSTRACT Herbaria represent irreplaceable repositories of biodiversity and are used to answer questions about conservation, ecology, systematics, and other sciences. In this sense, we characterize the infrastructure, human resources, and idiosyncrasies of Brazilian herbaria. To achieve this goal, curators were sent a structured and standardized questionnaire

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. Medium and large sized mammals of the Boqueirão da Onça, North of Bahia State, Brazil
ABSTRACT The mosaic of protected areas of Boqueirão da Onça (8.636 km²), created in the north of Bahia state, is located in the Caatinga, an exclusively Brazilian biome, but exposed to a range of anthropic impacts that threaten its species and natural resources. Few data are available for various zoological groups in Caatinga, including mammals. In order

6. Satellite Spectral Data on the Quantification of Soil Particle Size from Different Geographic Regions
ABSTRACT: The study of soils, including their physical and chemical properties, is essential for agricultural management. Soil quality must be maintained to ensure sustainable production of food and conservation of natural resources. In this context, soil mapping is important to provide spatial information, which can be performed using remote sensing (RS) te

7. PROTECTED AREAS AND THEIR MULTIPLE TERRITORIALITIES - A SOCIAL AND ENVIRONMENTAL REFLECTION ON CATIMBAU NATIONAL PARK - BRAZIL
Abstract In the 1970s, the social impacts of protected areas (PAs) began to be widely recognized as conservationist thinking and human rights evolved to an acceptance that conservation can be achieved in collaboration with traditional communities. However, such a 'human face' given to conservation is still not present in some 21st century PAs: Catimbau Natio

8. Estimates of Annual Soil Loss Rates in the State of São Paulo, Brazil
ABSTRACT: Soil is a natural resource that has been affected by human pressures beyond its renewal capacity. For this reason, large agricultural areas that were productive have been abandoned due to soil degradation, mainly caused by the erosion process. The objective of this study was to apply the Universal Soil Loss Equation to generate more recent estimate

9. Food consumption as an indicator of the conservation of natural resources in riverine communities of the Brazilian Amazon
RESUMO O presente estudo analisou e comparou o consumo diário de alimentos de origem animal em onze comunidades dos rios do Baixo Amazonas, Trombetas, e Purus, representando três diferentes sistemas de manejo e níveis de conservação na Amazônia brasileira. Todos os alimentos de origem animal foram pesados em pelo menos 10% das famílias das comunidades

10. Consequences of suppressing natural vegetation in drainage areas for freshwater ecosystem conservation: considerations on the new "Brazilian forest code"
The input of particulate and dissolved organic matter (POM and DOM, respectively) from terrestrial ecosystem drainage basins is an important energy and nutrient source in limnic food chains. Studies indicated that semi-deciduous seasonal forests located in drainage areas in Brazil have the potential to produce 7.5 - 10.3 Mg ha−1/year of POM. The global inc

12. Diversidade de fontes de pólen utilizadas por abelhas Centridini em áreas de Cerrado / Diversity of pollen sources used by Centridini bees in areas of Cerrado. Dissertation in Ecology and Conservation of Natural Resources
As abelhas nativas são os principais responsáveis pela polinização em áreas naturais e nos sistemas agrícolas. Nesse contexto, informações sobre as fontes de recursos alimentares e os padrões de utilização dessas por abelhas simpátricas podem subsidiar ações de conservação e manejo desse grupo. Nesse trabalho apresentamos informações sobre
