Conteúdo: |
Com o objetivo de avaliar a influencia dos niveis de Mg sobre a producao de materia seca de feijoeiro (Phaseolus vulgaris L. cv. Carioca), empregou-se a solucao nutritiva n. 2 de Hoagland & Arnon, modificada pela variacao da concentracao desse mineral, obtendo-se os niveis de 2,4; 24,3; 48,6; 72,9 e 97,2 ppm de Mg. O experimento foi realizado em blocos ao acaso, com tres repeticoes, em esquema fatorial, com cinco niveis de Mg e cinco colheitas, realizadas a intervalos de 14 dias. Os resultados, avaliados em relacao aos observados nas plantas submetidas a tratamento com 48,6 ppm de Mg, demonstraram que plantas nutridas com nivel de Mg acima desse, nao apresentaram alteracoes pronunciadas, enquanto foram marcantes os aumentos do peso de materia seca do caule,folhas e total da planta, com a utilizacao de 2,4 ppm de Mg. Tais resultados sugerem que, para o Phaseolus Vulgaris cv. Carioca o nivel de 2,4 ppm de Mg seria o ideal quando sao considerados os pesos da materia seca dos orgaos estudados. |

Abstract Habitat loss and natural vegetation fragmentation are significant causes of global biodiversity decline, impacting plant and animal species negatively. This issue is worrisome in the private areas of Cerrado in Brazil, which is the second-largest biome, considered a hotspot for biodiversity conservation, and a provider of ecosystem services. Herein, we present a novel integrated approach to define priority areas for biodiversity conservation and environmental compensation in Cerrado, using multicriteria analysis. Our approach combines variables like deforestation projection, integral index of connectivity, threatened species occurrence, and environmental information of rural properties, ranking the importance of remaining native vegetation for biodiversity conservation and forest certificate issuance. Landscape metrics were used to observe and predict land use and land cover changes from 1988 to 2038. We found a loss of native vegetation in the Cerrado superior to 20% between 1988 and 2018, associated with increased of its fragmentation and its connectivity loss, especially after 2008. Natural cover was replaced mostly by pasture and more recently by agriculture. Moreover, we determined that is expected a loss of native vegetation of around 55% by 2038 in the study area. The proposed approach can predict the consequences of future changes in the landscape of the private areas in the Cerrado biome. It should be replicated in other ecosystems, supporting the decision-making process for biodiversity protection.
