1. Modelos de distribuição de espécies de vellozia (Velloziaceae) endêmicas da Cadeia do Espinhaço e o efeito amostral sobre os mapas preditivos
The effectiveness of conservation actions depends on the knowledge of the geographical distribution of species. However, this knowledge is far from being achieved for most species, especially those occurring in mountainous tropical environments, such as the rocky fields (campos rupestres) of the Espinhaço Range, characterized by forming islands of vegetatio

2. Pequi, Jatobá, Algodãozinho ... : a biodiversidade do Cerrado na medicina popular / Pequi, Jatobá, Algodãozinho ... : The biodiversity of the Cerrado en popular medicine
The domain of Cerrado is pressed by many economic activities. It shares space, especially with livestock, soybeans, corn and sugarcane, compromising its flora, fauna and culture of Cerradeiro People. Paradoxically, it is one of the richest biomes in biodiversity. To encourage / support practices attentive to this peculiarity soften its intense anthropogenic

3. A service-oriented infrastructure for ecological niche modelling. / Uma infraestrutura orientada a serviços para a modelagem de nicho ecológico.
Ecological niche modelling combines environmental data and information about the occurrence of a species to obtain models to describe its probabilistic distribution in a region. Computational algorithms generate models based on the hypothesis that, if a species was found under the conditions which define its niche, then it may survive in any place which offe

4. Enhancing spatial association rule mining in geographic databases / Melhorando a Mineração de Regras de Associação Espacial em Bancos de Dados Geográficos
A técnica de mineração de regras de associação surgiu com o objetivo de encontrar conhecimento novo, útil e previamente desconhecido em bancos de dados transacionais, e uma grande quantidade de algoritmos de mineração de regras de associação tem sido proposta na última década. O maior e mais bem conhecido problema destes algoritmos é a geração

5. Drosophilidae (insecta, diptera) do cerrado : relações faunísticas, distribuição geográfica e vulnerabilidade das espécies
The insects of the family Drosophilidae (Insecta, Diptera) are excellent biological models, and they were intensively studied in several disciplines. The study of these flies in Brazil began in the 19th century, and had a great advance from 1940s. Nevertheless, there is still a big gap on the ecology of these animals. The Cerrado (Brazilian savanna) is the s

6. GeOntoQuery - um mecanismo de busca em bancos de dados geográficos baseado em ontologias
Geographic Information System (GIS) are computational tools used to capture, store, consult, manipulate, analyze and print geo-referenced data. A GIS is a multi-disciplinary system that can be used by different communities of users, each one having their own interest and knowledge. This way, different knowledge views about the same reality need to be combine

8. A DATA MODEL FOR EXPLORATION OF TEMPORAL VIRTUAL REALITY GEOGRAPHIC INFORMATION SYSTEMS
Geographic information systems deal with the exploration, analysis, and presentation of geo-referenced data. Virtual reality is a type of human-computer interface that comes close to the way people perceive information in the real world. Thus, virtual reality environments become the natural paradigm for extending and enhancing the presentational and explorat

9. Visualization for constructing and sharing geo-scientific concepts
Representations of scientific knowledge must reflect the dynamic nature of knowledge construction and the evolving networks of relations between scientific concepts. In this article, we describe initial work toward dynamic, visual methods and tools that support the construction, communication, revision, and application of scientific knowledge. Specifically,
