The Municipality of Pinheiral located at the middle valley of Paraiba do Sul river, was at first of all
exploited in natural resources. Later in the colonial period, the coffee occupied the land until its
decline, followed by extensive livestock, predominant at present days (MENEZES, 1999).
Throughout this range of situations, the region have suffered a huge land degradation process,
mainly caused by severe erosions. This study was performed in a eroded area (gully) reclaimed
by reforestation with leguminous trees. The objective of this work was evaluate the state of
landscape reclamation using the epigeous soil fauna as a bioindicator. The following treatments
were evaluated: acacia trees stand, mimosas trees stand, the hill slope top part, inside the gully
with a mix of leguminous trees. It was also evaluated a secondary forest with 20 years near by
the site of the erosion as a reference area. Soil fauna was sampled at May 2000 and June
2006, using Pitfall traps (MOLDENKE, 1994).
In 2000 sampling the highest value for average richness was observed in the secondary forest
with nine groups found. In 2006 sampling, the average richness for the mimosas stand, the top
part of the hill slope and gully were similar to forest. There was an increase in the number of
groups found from 2000 to 2006 sampling, which shows a improvement in the reclamation
process and system stability. It was observed increases from 38 to 110% in total richness. At the
acacia trees stand there was an intense colonization of ants, which had a negative effect on the
values of the of Shannon-Weaver and Pielou indices. These results show an evolution in the
reclamation process and how soil fauna is responsive to biotic factors present in the medium.
Based on the principal components analysis (PCA) it was clear the difference between the
years 2000 and 2006, since they were in total opposition. The mimosas trees stand was the
treatment that showed high degree of regeneration according to the PCA, being close to the
forest. The most of fauna groups were associated secondary forest and the mimosas trees

A construção de represas pode aumentar a emissão de gases do efeito estufa (GEE), principalmente metano (CH4) pela decomposição anaeróbica dos resíduos florestais, como galhos, ramos, folhas e miscelânea inundados. Objetivou-se, neste estudo, avaliar a emissão de CH4 após a inundação do solo coberto com resíduos florestais. Unidades experimentais foram construídas com tubos de PVC contendo solo e diferentes combinações de dose (0; 21,2; 42,3 e 64,1 Mg ha-1) e tipo de resíduos (folhas, ramos e miscelânea, galhos e composição original) e água de rio. O delineamento experimental foi inteiramente casualizado com arranjo fatorial e três repetições. As taxas de emissão de CH4 foram monitoradas em 19 eventos durante um ano (Fevereiro/2012 a Março/2013). Cerca de 75 dias após a incubação do solo com resíduos florestais verificou-se aumento das emissões de CH4, ocorrendo dois picos de emissão, aos 111 e aos 249 dias. A emissão acumulada de CH4 no primeiro ano de alagamento foi de 200 g C m-2 na dose zero, passando a valores próximos a 400 g C m-2 nas doses de 21,2 Mg ha-1 e maiores, não havendo efeito do tipo de resíduo, apenas da dose, como fator isolado. |
