1. Biofertilizante de rochas mais matéria orgânica inoculada com bactéria diazotrófica na cana-de-açúcar.
Sugarcane (Saccharum spp.) Is currently considered one of the most important crops in the Brazilian social and economic. In Pernambuco, the sugar cane industry occupies an important agricultural area with high sugar and ethanol, generating many direct and indirect jobs. For increased productivity becomes necessary the use of management technologies that fost

2. Decomposição de resíduos da colheita e transferência de carbono para o solo em plantações de eucalipto / Harvest residue decomposition and carbon transference to the soil in eucalypt plantations
In Brazil, eucalyptus is planted in regions with different climate and soil conditions, which affect harvest residue decomposition and the rate of carbon transference fromresidues (Cres) to the soil, hence influencing soil organic matter (SOM) content. SOM is considered one of the most important indicators of soil quality and forest production sustainability

4. Estrutura e produtividade de manguezais de colonização recente em Florianópolis, SC
This study aimed to evaluate the structure and productivity of recently colonized mangrove forests with different ages, in Saco dos Limões, Florianópolis, SC. To do that we chose 4 areas of different ages with 2 plots in which (1M, 1E, 2M, 2E, 3M, 3E, 4M, 4E). Sediment was sampled and analyzed for grain size, organic matter and carbonate levels. The studie

5. Characterization of the humic substances extracted from the soil of the Pai Matos mangrove forest (Cananéia, SP, BR) and Spanish salt marshes (Galicia and Valencia) / Caracterização das substâncias húmicas extraídas do solo do manguezal de Pai Matos (Cananéia, SP, BR) e de marismas da Espanha (Galícia e Valência)
Os objetivos deste estudo foram: 1) avaliar por meio da análise elementar (C, N, H, S, O), Ressonância Paramagnética Eletrônica (RPE), e Espectroscopia de Infravermelho com Transformada de Fourier (FTIR) às características dos ácidos húmicos (AHs) extraídos do solo do manguezal de Pai Matos (Cananéia-SP-BR) sob diferentes tipos de vegetação (Rhiz

6. SOIL RECUPERATION IN FOREST SETTLEMENTS IN MINING AREAS IN THE TREMEMBE MUNICIPALITY - SP / RECUPERAÃÃO DO SOLO EM POVOAMENTOS FLORESTAIS EM ÃREA DE EXPLORAÃÃO DE AREIA NO MUNICÃPIO DE TREMEMBÃ-SP
The recuperation of degraded areas due to mining activity namely sand mining is carried out by the forest recomposition with native species. In the present work the availability of nutrients along with amount of living matter cover accumulated in a native ciliary wood and in five fragments of forest recomposition of areas previously used for sand mining in t

7. Influence of the litter accumulated in the base of the palm Attalea ataleoides (Barb.Rodr.) Wess. Boer in the ant community in a terra firme forest in Central Amazonia / Influence of the litter accumulated in the base of the palm Attalea ataleoides (Barb.Rodr.) Wess. Boer in the ant community in a terra firme forest in Central Amazonia / Influência da serrapilheira acumulada na base da palmeira de sub-bosque Attalea attaleoides(Barb. Rodr.) Wess. Boer (Arecaceae) sobre a comunidade de formigas (Hymenoptera, Formicidae) em uma floresta de terra firme da Amazônia Central / Influência da serrapilheira acumulada na base da palmeira de sub-bosque Attalea attaleoides(Barb. Rodr.) Wess. Boer (Arecaceae) sobre a comunidade de formigas (Hymenoptera, Formicidae) em uma floresta de terra firme da Amazônia Central / Influence of the litter accumulated in the base of the palm Attalea ataleoides (Barb.Rodr.) Wess. Boer in the ant community in a terra firme forest in Central Amazonia / Influência da serrapilheira acumulada na base da palmeira de sub-bosque Attalea attaleoides(Barb. Rodr.) Wess. Boer (Arecaceae) sobre a comunidade de formigas (Hymenoptera, Formicidae) em uma floresta de terra firme da Amazônia Central
Foi investigada a influência da serrapilheira acumulada na base e adjacências de Attalea attaleoides (Barb. Rodr.) Wess. Boer sobre a composição de formigas encontradas no chão de uma floresta de terra firme da Amazônia Central. A mirmecofauna foi amostrada na serrapilheira da base de 80 palmeiras e na serrapilheira adjacente à base destas. As amostra

8. A new species of Ibitermes (Isoptera, Termitidae) from the Atlantic forest, northeastern Brazil
The sterile castes of Ibitermes inflatus sp. nov. from Rio Tinto, State of Paraíba, Brazil are described and illustrated. This is the first record of a species of Ibitermes from the Brazilian northeast and from the Atlantic Forest biome. The absence of ridges in the molar plate of the left mandible and the presence of granules of sand and silt mixed with or

9. Nitrous Oxide Emission Associated with Autotrophic Ammonium Oxidation in Acid Coniferous Forest Soil
Aerobic N2O production was studied in nitrifying humus from urea-fertilized pine forest soil. Acetylene and nitrapyrin inhibited both NH4+ oxidation and N2O production, indicating that N2O production was closely associated with autotrophic NH4+ oxidation. N2O production was enhanced by low soil pH; it was negligible above pH 4.7. When soil pH decreased from

10. Degradation of Humic Acids by the Litter-Decomposing Basidiomycete Collybia dryophila
The basidiomycete Collybia dryophila K209, which colonizes forest soil, was found to decompose a natural humic acid isolated from pine-forest litter (LHA) and a synthetic 14C-labeled humic acid (14C-HA) prepared from [U-14C]catechol in liquid culture. Degradation resulted in the formation of polar, lower-molecular-mass fulvic acid (FA) and carbon dioxide. HA

11. Phospholipid Fatty Acid Composition, Biomass, and Activity of Microbial Communities from Two Soil Types Experimentally Exposed to Different Heavy Metals
The phospholipid fatty acid (PLFA) pattern was analyzed in a forest humus and in an arable soil experimentally polluted with Cd, Cu, Ni, Pb, or Zn at different concentrations. In both soil types, there were gradual changes in the PLFA patterns for the different levels of metal contamination. The changes in the forest soil were similar irrespective of which m

12. Soil Bacterial Biomass, Activity, Phospholipid Fatty Acid Pattern, and pH Tolerance in an Area Polluted with Alkaline Dust Deposition
Soil bacterial biomass, phospholipid fatty acid pattern, pH tolerance, and growth rate were studied in a forest area in Finland that is polluted with alkaline dust from an iron and steel works. The pollution raised the pH of the humus layer from 4.1 to 6.6. Total bacterial numbers and the total amounts of bacterial phospholipid fatty acids in the humus layer
