1. Surface sealing and water erosion of soils with mulching in the semi-arid region of Brazil
RESUMO A avaliação do processo de selamento superficial em solos da região semiárida Brasileira é de grande relevância para compreensão do processo e tomada de medidas mitigatórias. Objetivou-se avaliar o selamento superficial e características físico-hídricas dos principais solos da Bacia Representativa do Alto Ipanema, Pesqueira-PE, sob influên

2. Visual Evaluation of the Soil Structure under Different Management Systems in Lowlands in Southern Brazil
ABSTRACT The “Visual Evaluation of Soil Structure” (VESS) is a method used primarily to evaluate the soil structural quality of Oxisols in Brazil and secondly for more specific research, consultancy, and teaching purposes. Since the methodology was never applied and compared with laboratory evaluations of physical properties of hydromorphic soils of the

3. Nutrient cycling between soil and leaf litter in the Cerrado (Brazilian savanna) on eutrophic and dystrophic Neosols
ABSTRACT We evaluated nutrient cycling by measuring leaf litter production and decomposition in the Brazilian savanna (cerrado sensu stricto) on eutrophic (calcareous) and dystrophic (arenitic) Neosols over the same spatiotemporal scale. We installed three transects in the Cerrado with plots in each Neosol type. Areas along the transects were randomly chosen

4. Soil and leaf nutrient content of tree species support deciduous forests on limestone outcrops as a eutrophic ecosystem
The leaf and soil nutrient status of plants has been used to infer structural and functional aspects at the ecosystem level. Such data are available for tropical and savanna systems growing on poor and acidic soils; however, information for species growing on eutrophic and basic soils is lacking. Deciduous tropical forest is one of the most endangered types

5. Gradientes edáficos e sua relação com as fitofisionomias do semi-árido meridional brasileiro / Edaphic gradients and their relationship with the vegetation types of semi-arid southern Brazil
The semi-arid region in Brazil represents a significant territorial extension, where the climate is markedly seasonal, with low rainfall, high evapotranspiration and higher temperatures. Its southern portion comprises the northern boundary between the states of Minas Gerais and Bahia. This region is dominated by dry forest vegetation type, however, different

6. Micorriza arbuscular: um bioindicador da fertilidade dos solos e da distribuição de árvores no bioma cerrado.
RESUMO: A grande variedade de fitofisionomias existentes no Bioma Cerrado tem sido associada a diferentes fatores ambientais como clima, relevo, geologia, entre outros. O fator solo exerce influência fundamental nessa diversidade ambiental. As suas características químicas, físico-hídricas e biológicas formam um complexo de inter-relações, muitas vez

7. Padrões florísticos e estruturais das Florestas Estacionais Semideciduais do Triângulo Mineiro, MG / Floristic and structural patterns of semideciduous seasonal forests of Triângulo Mineiro, MG
The semideciduous seasonal forests (SSF) of southeastern Brazil have a high floristic diversity, accompanied by a high beta diversity, even between nearby fragments. However, nowdays these forests have been represented by a large number of small fragments, a landscape pattern typical for this region. In addition to the processes related to fragmentation, the

8. Caracterização de solos em uma topoclimossequência no maciço de Triunfo - Sertão de Pernambuco / Characterization of soils along a topoclimosequence in Triunfo mountain-semi-arid of Pernambuco state
High altitude forest in mountain of Northeast Brazil are islands of the Humid Atlantic forest in the middle of semi-arid region, with an atypical climatic condition, improved by the occurrence of orographic precipitions that can reach more than 1200mm per year. In Pernambuco state scientific studies in these humid sites were only related to botanic and biolo

9. Atributos do solo, ambientes e perdas de solo para Ãreas florestadas no sul e leste do Brasil / Soil properties, condition and soil losses for south and east Brazilian forest areas
Eucalyptus cultivation has increased in all Brazilian regions. In order to recommend good management practices it is necessary to understand differences in soil properties where eucalyptus is planted. In addition, aggregate stability analyses have proved to be a useful tool to measure soil effects caused by changes in management practices. Besides, the evalu

11. Evaluation of the stock and isotopic composition of carbon in the soil of Acre. / Avaliação do estoque e composição isotópica do carbono do solo no Acre.
The State of Acre is located in the extreme west of Brazil, occupying an area that had great geological influence from the mountain chain of Andes. The soils present pedologic characteristics very different from the ones found in the remaining of Brazilian Amazon, prevailing Inceptisols, Alfisols, and Ultisols, generally eutrophic, young and little weathered

Limnological research is very scarce in tropical areas, particularly if we consider that of long duration. This research was carried out at the âLagamar do CauÃpeâ (a coast plain in Caucaia town, CearÃ, Brazil, during the period from June, 2001 to February, 2002, aiming at making a diagnosis about the physical, chemical and environmental characteristics
