1. Technical efficiency analysis of marine shrimp farming (Litopenaeus vannamei) in biofloc and conventional systems: A case study in northeastern Brazil
Abstract Shrimp farming has a great ecological, economic, and social importance in northeastern Brazil. Although the conventional farming system is widely used, biofloc technology (BFT) system has been developed to reduce environmental impacts and optimizing the production. Thus,the present study evaluated the technical efficiency of production cycles of Lit

3. Composition of shrimp populations (Crustacea: Decapoda) in non-vegetated areas of two river islands in a Brazilian Amazon estuary
This study investigates the shrimp found in non-vegetated areas of an estuary of the Amazon River. We ascertained the input of juveniles, species' biometrics and the influence of environmental factors on the abundance of species. The samples were collected monthly, from August 2006 to July 2007, in two places in the estuary, each next to an island. For colle

4. Evaluation of maize core collection for drought tolerance.
The maize genebank (GBmaize) preserves nearly 4,000 accessions for conservation and use. The use is however restricted because the accessions do not performs as well as the elite genotypes. This problem can be reduced by pre-breeding, i. e., by extending the information on germplasm and introgressing useful alleles. Since irregular rainfall distribution and

5. Sustentabilidade de uma propriedade rural de base ecológica : um estudo de caso no Sítio Oliveira em Rio Claro/SP / Sustainability of a farm with ecological production systems: a case study in Sítio Oliveira in Rio Claro/SP
Most of the territorial space of a city is used for agricultural purposes like crops, livestock or forest and a considerable amount of ecological problems are related to such activities, which, as productive processes, are closely linked to the dynamics of ecosystems and certain social relationships of production. In agriculture, sustainability is a guiding

6. Dos mitos acerca do determinismo climático/ambiental na história do pensamento geográfico e dos equívocos de sua crítica: reflexões metodológicas, teórico-epistemológicas, semântico-conceituais e filosóficas como prolegômenos ao estudo da relação sociedade-natureza pelo prisma da idéia das influências ambientais / On myths around climate/environmental determinism in geographic thought history and mistakes of its criticism: methodological reflections, theoretical-epsitemological, semantic-conceptual and philosophical introduction of the study in relation to nature-society through environmental influence view
Na história do pensamento geográfico há um grande equívoco na maneira pela qual é concebida a teoria do determinismo geográfico/ambiental. Isso significa que o tema tem sido tratado sob estereotipada roupagem, empobrecendo a Geografia e difamando e subestimando inúmeros geógrafos, bem como suas obras e idéias. O primeiro grande objetivo é o de demo

7. Effects of changes in land use of the Brazilian Amazon on the ecological services provided by EscarabeÃneos (Coleoptera, Scarabaeidae). / Efeitos da alteraÃÃo do uso do solo na Amazonia Brasileira sobre serviÃos ecolÃgicos proporcionados pelos Scarabaeinae (Coleoptera, Scarabaeidae)
Ecosystem services provided by the biodiversity are that ones associated to live organism and that, in last analysis, affect natural process of human interest. Scarabeine dung beetles has been in evidence in the last years in function of the array of services provided, both in natural as in agricultural landscapes. This work aimed to evaluate the effect of l

8. Condições ambientais envolvidas na saúde e na doença da população de Muzambinho - Minas Gerais sob a ótica de atores sociais
Although the term environment is widely known and comprehends interactions among all nature components, including human beings, the complexity of the interactions may hinder people from recognizing that they are a part of the environment.

The relationship between man and environment initially happens in a natural way. After a while, there is an accelerated populational growth, and new technology comes, which intensifies the human actions both in the terrestrial environment and in the aquatic one, imposing, therefore, unbalance in the relation man-nature. Thus, quantitative and qualitatively,

Planet Earth seen from outer space, as shown by numerous satellites photographs, reveals an impressive beauty. What is the cause of such beauty? Surely it is water. Throughout the centuries, the complexity of the multiple uses of water by man increased and produced an enormous set of degradation and pollution. On the other hand, the excessive multiple uses a
