2. 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

4. Solar radiation valuation in tropical mangrove ecossystem in Alagoas, Brazil / Avaliação da radiação solar em ecossistema de manguezal tropical em Alagoas, Brasil
As florestas de manguezais são de extrema importância social, econômica e ambiental, pois as mesmas são detentoras de uma rica fauna e flora. O Brasil possui uma das maiores áreas de manguezais do mundo que se estende desde o extremo Norte até o Sul do país. Atualmente uma das grandes questões ambientais diz respeito ao desmatamento das áreas de flo

5. Balanço de radiação, energia e fluxo de CO2 em ecossistema de manguezal na Amazônia / Radiation and energy balance and fluxes of CO2 in a Amazon mangrove ecosystem
This work use the longest series of continuous meteorological data and fluxes measurements of CO2, sensible heat and latent heat made in Amazon mangrove ecosystem. The series used in this study corresponds to the period of November, 2002 to August, 2003. The meteorological data were collected using an EDISOL system based on the hedí covariance technique. Th

6. ECO - An ecossystem for agile web systems development / ECO - um ecossistema para o desenvolvimento ágil de sistemas web
The vertiginous expansion of the use of the Web Systems as business tool imposed great pressure on the software development, demanding delivery of tangible result faster time, in an unstable and highly dynamic environment. In response to these necessities, appeared a new methodology class of software development: Agile Methodologies. This work presents the m

7. Rhizophora mangle (red mangrove) in contaminated areas of mangrove from Baixada Santista / Rhizophora mangle (Mangue vermelho) em áreas contaminadas de manguezal na Baixada Santista
Os Manguezais são ecossistemas de grande importância ecológica, social e econômica. Tendo em vista que estas áreas vêm sofrendo degradações, em especial a contaminação por resíduos e efluentes contendo metais pesados, que interferem na estabilidade ambiental, torna-se importante identificar o nível de interferências destes contaminantes sobre o

8. Atenuação, pela associação micorrizica arbuscular, do estresse causado por cadmio em plantas
Cd accumulation by plants and the increasing presence of this metal in the soil system is nowadays of great environmental concern. Cd contamination can bring human health problems and harmful effects to the soil ecossystem. Arbuscular mycorrhiza (AM) is considered a universal symbiosis between higher plants and fungi from the order Glomales. This symbiosis i

9. Sward structure, light interception and herbage acummulation of marandu grass swards submitted to grazing intensities by continuous stocking regimes. / Estrutura do dossel, interceptação luminosa e acúmulo de forragem em pastos de Capim-Marandu submetidos a alturas de pastejo por meio de lotação contínua.
In a pastoral ecossystem the interception of incident radiation is the first step of a sequence of events that results in herbage production. Several are the factors interfering on the light interception process including sward leaf area index, structure and architecture. The objective of this experiment was to study sward struture, light interception and he

10. Characterization of soils degraded by the agricultural activity and biological changes after reforestation with different species associations of the Atlantic Forest / Caracterização de solos degradados pela atividade agrícola e alterações biológicas após reflorestamentos com diferentes associações de espécies da Mata Atlântica
This study seeks to: a) characterize the degree of physical and chemical degradation of the soils used in agricultural cultivation for several decades, originally covered by the Atlantic Forest (Seasonal Semideciduous Forest) in Botucatu, SP; b) evaluate the biological changes of these soils along a 16-month post-reforestation with different models of specie
