Geographic Information Systems (GISs) are composed of useful tools to map and to model the spatial distribution of events that have geographic importance as schistosomiasis. This paper is a review of the use the indicator kriging, implemented on the Georeferenced Information Processing System (SPRING) to make inferences about the prevalence of schistosomiasis and the presence of the species ofBiomphalaria, intermediate hosts ofSchistosoma mansoni, in areas without this information, in the Minas Gerais State, Brazil. The results were two maps. The first one was a map ofBiomphalariaspecies, and the second was a new map of estimated prevalence of schistosomiasis. The obtained results showed that the indicator kriging can be used to better allocate resources for study and control of schistosomiasis in areas with transmission or the possibility of disease transmission.

<p>No interior do estado de Minas, o crescimento total bruto de matrículas no ensino superior, entre 1991 e 2010, foi de 371,82%, relativamente maior do que o nacional (309,41%). Cabe, portanto, uma análise sobre as formas de polarização e as características da mobilidade pendular de estudantes na rede de centros regionais no estado. Neste artigo, avaliam-se os fluxos e os padrões de distribuição das redes de pendularidade de estudantes entre os centros regionais do interior do estado de Minas Gerais, tendo como base os dados do Censo Demográfico de 2010. Foram analisados os movimentos de pendularidade de estudantes de vinte e dois centros considerados de alta centralidade, aqui denominados sub-regionais. A interpretação foi elaborada por meio da avaliação das redes de distribuição espacial, conjugada com a mensuração de indicadores como a Distância Média ponderada (DMp) e a Razão de pendularidade escolar (RPe), o que permitiu a distinção dos movimentos estudantil e laboral. Os resultados indicam a magnitude de deslocamentos intrarregionais e maior abrangência espacial de polarização de cinco sub-centros regionais. Quinze municípios apresentaram RPe maior que um, ou seja, possuem a prevalência na atração da pendularidade estudantil, o que mostra a relevância do papel das instituições de ensino na atração populacional.</p><p><span>Abstract</span></p><p>NETWORKS OF STUDENTS’ PENDULAR MOVEMENTS FOR THE SUBREGIONAL POLES OF THE COUNTRYSIDE OF MINAS GERAIS</p><p>In the countryside of Minas Gerais state (MG), the absolute growth in the period between 1991 and 2010 was of 371,82%, which is a bit higher than the National growth (309,41%). Such context raises questions about the forms of polarization and the students’ pendular fluxes between regional centres. In this article I evaluate these fluxes and the patterns of distribution of the networks of students’ pendular motion among the regional centres of the countryside of MG based on the data of the Demographic Census of 2010. I analysed students’ pendular movements from 22 centres located in the exact centre of the state, which I named “subregionals” for the purposes of this paper. My interpretation was built through the evaluation of the networks of spatial distribution compared with the measurement of the Average Weighed Distance (DMp in Portuguese) and with the Rate of Students’ Pendular Movements (RPe in Portuguese), which allowed me to distinguish between the students’ and workers’ movements. The results I obtained reveal the magnitude of the interregional movements and a higher spatial encompassment of the polarization of five regional centres, seats of Federal Universities. Fifteen municipalities have shown an RPe higher than 1, which means they present a prevalence of students’ pendular movements, revealing the importance of theeducational institutions’ role in the spatial dynamics of the population.</p>

Megalancistrus barrae is a species endemic to the São Francisco River basin that has not previously been recorded from the Upper São Francisco basin.The present work increases the known distribution of the species by reporting new collections from two different regions in the Upper São Francisco basin: one in the Pará River and the other in the São Francisco River, downstream Três Marias dam, Minas Gerais state. In addition, this study compiles distributional data on Megalancistrus barrae from museums.
