Abstract Aim Mining activities generate countless environmental impacts, including heavy-metal contamination, sorting and increased turbidity. In aquatic ecosystems these impacts can drastically affect the initial links of food chain, such as zooplankton. Methods To evaluate how different mining influence structure functional diversity zooplankton, we investigated geochemical characteristics water sediment in two small impoundments impacted by (kaolin iron extraction). We also explored...
Nos últimos quarenta anos, o Parque Estadual do Itacolomi (PEI), localizado na região de Ouro Preto, Minas Gerais, esteve sujeito a várias mudanças em seus padrões uso e ocupação solo. Essas foram registradas quantificadas através sensoriamento remoto técnicas geoprocessamento, com as quais se efetuou mapeamento das transformações no da área durante essas quatro décadas. A fim avaliarem ocupação, definidas seguintes classes vegetacionais: Floresta Estacional Semidecidual, Campos Rupestres...
Abstract Located in the municipalities of Ouro Preto and Mariana, Quadrilátero Ferrífero (QF) Minas Gerais, Itacolomi State Park (ISP) shelters more than 7,000 ha remnants Atlantic Forest campos rupestres. The QF region has high biodiversity is being highly impacted, mainly by mining activities. Aiming to organize available floristic information support related research, this study presents list phanerogamic species ISP major vegetation types. This survey was carried out from October/1992...
Soil erosion is a major problem observed in terrestrial ecosystems. Monitoring and identifying potential areas for becomes extremely important the better management of these areas. The main aim this study was to develop Geographic Information System script tool based on universal soil loss equation (USLE), which calculates three large agricultural sub-basins. Algorithms were implemented graphical interface ModelBuilder later Python programming language, thus allowing creation specific...
A bstract Restoration of tropical riparian forests is challenging, since these ecosystems are the most diverse, dynamic, and complex physical biological terrestrial habitats. This study tested whether biodiversity can predict ecosystem functions in a human-impacted forest. We explored effects several components (taxonomic or functional groups) on different associated with restored Overall, 49% showed positive functions, each component to degree. In general, our results that both taxonomic...
Purpose – The purpose of this research was to identify the major environmental impacts occurring in Melo Creek, Minas Gerais, Brazil, especially as regards its water quality.
This study analyzed the presence of Biomphalaria in Melo creek basin, Minas Gerais state, and its relationship to irrigation canals. Seventeen these canals were used determine a limnological, morphological hydrological characterization during an annual seasonal cycle. samples sent René Rachou Research Center/FIOCRUZ for identification parasitological examination. Six identified as breeding areas mollusks one them it was registered coexistence B. tenagophila (first report this basin) glabrata...
Os processos erosivos, apesar de naturais, vêm sendo intensificados pelo uso inadequado do solo provocando a perdas anuais bilhões toneladas solos férteis em todo o mundo. Assim, compreender este processo é fundamental para um desenvolvimento sustentável da atividade agrícola. Este trabalho avaliou as por erosão laminar sete parcelas, sob diferentes tratamentos (mata; cultivo soja, milho e cafeeiro, pastagem exposto), Latossolos vermelhos Fazenda Esmeril, Patrocínio, MG. As parcelas exposto...
No presente trabalho analisaram-se as percepcoes sobre os problemas ambientais reveladas pelos discentes de oito cursos superiores do Instituto Federal Goiano – Campus Urutai e algumas instâncias relacionadas a essas percepcoes, como abordagem da Educacao Ambiental (EA) nos cursos. Para isso, um questionario objetivo foi aplicado 191 alunos. Observou-se que alunos possuem uma boa percepcao o significado atribuem aos “poluicao dos recursos hidricos”, ar”, “escassez agua potavel”, status mais...
Purpose Of the numerous hydrogeochemical river‐water transformations provoked by intense and irrational soil practices, heavy metal contamination agrochemical usage is most worrisome. Long‐term accumulation can be transported rainwater, during storms, contaminating rivers. Data on this type of are still scarce, principally in developing countries, such as Brazil. This paper aims to evaluate influence agricultural activities hydrogeochemistry Paracatu River's sub‐basins....

Em relacao aos demais tratamentos, a mata apresentou os menores totais, aproximadamente 38%; dentre as culturas, o milho (79%), seguido da soja (68%), foram que apresentaram maiores para bem superiores ao area cafezal e pasto, 47% 45%, respectivamente. Apesar do sistema plantio direto nas culturas ter reduzido producao sedimentos nestas areas, estas ainda continuam perdendo muito material durante fases preparacao solo plantio. Ja valor...

A erosão por ondas em reservatórios está entre os processos que mais remodelam suas margens e promovem seu assoreamento. continuidade destes causa inúmeros problemas não só ambientais, mas também econômicos. Infelizmente, poucos são trabalhos modelos tratam do assunto a maioria deles usa um número restrito de parâmetros análises. Uma das variáveis menos utilizada é presença/tipo vegetação, provavelmente pela dificuldade se estimar impacto direto. Para avaliar influência da existência matas...
