Os resultados das técnicas de restauração ecológica podem ser monitorados pelos indicadores biológicos de qualidade de solo, como a fauna de artrópodes associada à serapilheira. Este estudo teve o objetivo de verificar o efeito imediato da aplicação da técnica de transposição de galharia, em uma área degradada de cerrado. Os dados são referentes à fauna de artrópodes associada à serapilheira de quatro áreas: uma degradada com braquiária; duas experimentais de transposição de galharia, com e sem a presença de mamona; e uma de cerrado nativo. Foram encontrados 7.660 indivíduos, pertencentes a 23 táxons. Acari e Collembola foram os táxons mais abundantes em todas as áreas estudadas, seguidos por Coleoptera, Diptera, Hemiptera, Hymenoptera e Symphyla. A área de transposição de galharia sem mamona destacou-se das demais por diferenças nas abundâncias dos táxons, por um índice de diversidade mais alto e pela baixa dominância, constituindo indícios de alteração na comunidade do solo. As evidências demonstram que a presença da mamona prejudica a sucessão inicial, influindo negativamente na restauração ecológica.

The 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.

The presence of residues of the major groups of pesticides (organohalogen, organophosphorous, pyrethroids and organonitrogen) in representative samples of honey produced in Bauru (state of São Paulo, Brazil) was investigated from 1999 through2004. A multiresidue method was applied to honey samples to determine 48 pesticides with recoveries ranging from 76 to 95%. The limits of detection found were lower than 10 µg/kg for GC-MS-SIM. The results indicated that most pesticides found in the samples belonged to the organohalogen and organonitrogen groups. Residues of malathion were detected in almost all of the samples in high concentration.
