“…However, the seven months of soil management could have been adequate to investigate microbial changes in soil. Several authors have shown that the soil microbial community undergoes rapid changes in relation to environmental conditions (Faleiro & Andrade, 2011;Barros et al, 2010;Moreira & Siqueira, 2006). Furthermore, the AMF communities were most similar among samples from a similar geographical location (Figures 5 and 8).…”

The wastewater has been an environmental problem, but your used as fertilizers could reduce or eliminate the application of commercial fertilizers in soil. Arbuscular mycorrhizal fungi (AMF) and nitrogen fixing bacteria (NFB) are a good parameter to analyze the impacts of this fertigationon soil. We aimed to evaluate the distribution and diversity of AMF and NFB before and after applications of wastewater or manure from green line of a cattle slaughterhouse in the irrigation of B. brizantha cv Marandu in Cerrado soil and leaf biomass productivity. The experimental design was performed in completely randomized blocks with ten biofertigation managements. The seeds of the forage were distributed in grooves with spacing of 5 cm. This seeds were covered with a soil layer. NFB and AMF diversity was performed by denaturing gradient gel electrophoresis (DGGE). The leaf biomass productivity in the biofertigation managements was higher than in the managements without the use wastewater/manure. After biofertigation managements, changes in the DGGE profile of the NFB and AMF communities were observed. These changes may be due to the difference in the sample collection period and in the soil humidification. Thus, these DGGE profiles was a good parameter to diagnose the efficacy of wastewater/manure as an alternative biotechnological irrigation.

Due to the sensitivity the environmental and anthropogenic interferences, the NFB and AMF communities and the soil microbial activity are good indicators to soil quality (Barros et al, 2010).…”

“…The orders Acari and Collembola are the major constituents of soil mesofauna (Seastedt, 1984;Franklin et al, 2005;Yi et al, 2006;Barros et al, 2010), likely due to their high adaptive capacity (Yi et al, 2006), which is reflected in their feeding habits. According to Seastedt (1984), most Acari and Collembola species have mouthparts that can break down organic matter while they feed on the microflora (especially fungi) attached to it.…”

SUMMARYThe results of ecological restoration techniques can be monitored through biological indicators of soil quality such as the leaf litter arthropod fauna. This study aimed to determine the immediate effect of brushwood transposition transferred from an area of native vegetation to a disturbed area, on the leaf litter arthropod fauna in a degraded cerrado area. The arthropod fauna of four areas was compared: a degraded area with signal grass, two experimental brushwood transposition areas, with and without castor oil plants, and an area of native cerrado. In total, 7,660 individuals belonging to 23 taxa were sampled. Acari and Collembola were the most abundant taxa in all studied areas, followed by Coleoptera, Diptera, Hemiptera, Hymenoptera, and Symphyla. The brushwood transposition area without castor oil plants had the lowest abundance and dominance and the highest diversity of all areas, providing evidence of changes in the soil community. Conversely, the results showed that the presence of castor oil plants hampered early succession, negatively affecting ecological restoration in this area.Index terms: ecological restoration, signal grass, mesofauna, Acari, Collembola.(1) Extracted from the first author's Scientific Initiation submitted to the Department of Biological Sciences, UNESP -Univ Estadual Paulista, Campus

“…Although mining activity in the region ceased in the mid-1990s, close to 177,000 tons of Pb mining residues (tailings, slags) were left close to the company's facilities (Piedade et al, 2014) and are still deposited on the riverbanks. They are therefore an important source of contamination due to weathering processes, floods carriage, drag by rainfall, and percolation through the groundwater, among others (Andrade et al, 2009;Barros et al, 2010;Cotta et al, 2006;Gonçalves and Carvalho, 2006;Kummer et al, 2011;Piedade et al, 2014). Abessa et al (2014) compiled the information on the composition of the mining residues affecting RIR contamination levels and reported that both the tailings from local mines and the slags from the Plumbum plant included Pb, Cu, Cr, Zn and Ba, among other elements.…”

This study sought to assess the ecological risks of sediments from the northern portion of an estuarine protected area (Cananéia-Iguape-Peruíbe Protected Area--CIP-PA). The CIP-PA is located on the southern coast of São Paulo State, Brazil and is influenced by former mining activities along the Ribeira de Iguape River (RIR). We used a tiered approach based on multiple lines of evidence (geochemical analyses, toxicity tests, and whole sediment toxicity identification and evaluation) in order to assess environmental quality. The sediments presented a heterogeneous composition, but the samples collected close to the RIR exhibited higher concentrations of metals (Cd, Cr, Cu, Pb) and toxicity. Multivariate analysis showed that toxicity was associated with metals, mud, organic matter, and CaCO3 quantities. The whole-sediment toxicity identification evaluation approach indicated that ammonia and metals were responsible for sediment toxicity. Overall, we concluded that the sediments collected at depositional areas from the northern portion of the CIP-PA presented high levels of metals, which originated from former mining areas located in the upper RIR basin, and that this contamination had toxic effects on aquatic invertebrates. The tiered approach was useful for identifying the degradation of sediment quality and also for indicating the causes of toxicity. Because the CIP-PA is an important estuarine protected area that is ecologically at risk, large-scale measures are required to control the sources of contamination.
