ABSTRACT: Gullies are significant contributors to soil degradation in several regions of Brazil, including Minas Gerais, where erosion processes have caused soil loss. The characterization of erosion processes is crucial for the application of measures for recovering degraded areas and reducing erosion impacts. This study models soil loss with the use of InVEST software and assesses the impact of three different scenarios, namely (1) implementation of soil conservation practices and replacement of pasture areas for temporary agriculture, (2) reforestation of pasture areas, and (3) preservation of ciliary forests. Soil loss, sediment exportation, retention, and deposition for the present scenario (2019), as well as the three aforementioned hypothetical scenarios, were estimated. In the present scenario, the estimated mean annual soil loss was 2.75 t/ha year, with 1,449.54 t/year sediment exportation, 9,042.13 t/year retention, and 1,449.54 t/year deposition. The model predicted scenario 1 would result in 2.23 t/ha year mean annual soil loss, 1,300.59 t/year sediment exportation, 9,191.08 t/year retention, and 11,755.76 t/year deposition. Scenario 2 showed 1.92 t/ha year mean annual soil loss, 1,046.69 t/year sediment exportation, 9,444.98 t/year retention, and 10,229.77 t/year deposition, whereas the results for scenario 3 were 2.36 t/ha year, 616.65 t/year, 9,862.06 t/year, and 13,206.47 t/year, respectively. Reforestation and preservation of ciliary forests, along with soil conservation practices, were effective measures for reducing soil loss. Such findings are valuable for the management of areas degraded by erosion processes.

O objetivo deste trabalho foi determinar os recursos forrageados por Polistes versicolor em área de reflorestamento com eucalipto e identificar as presas forrageadas. No período de janeiro a dezembro de 2007, foram realizadas 24 observações da atividade forrageadora de colônias de P. versicolor presentes em um reflorestamento de eucalipto, em Juiz de Fora, MG, totalizando 240 horas de registros. Durante as dez horas de observação diária, foram registrados e qualificados, a cada 30 minutos, os retornos das operárias para a colônia. Foram registrados 1.809 retornos, dos quais 51,63% foram com néctar; 6,85%, com água; 4,7%, com fibra vegetal; 17,41%, com presas; e 19,40%, sem recurso forrageado (improdutivos). As operárias de P. versicolor predaram exclusivamente lagartas de lepidópteros, que foram a única fonte de proteína animal oferecida aos insetos imaturos, na colônia. Dessa forma, a espécie estudada apresenta potencial como agente controlador biológico de herbívoros desfolhadores de eucalipto. |
