[Landscape ecology of hantavirosis in Rio Grande do Sul state].

The aim of this work was to study the landscape ecology of hantavirosis in Rio Grande do Sul state, Brazil. This was achieved through geocoding the occurrence of cases and overlaying onto vegetation and relief maps. The majority of cases occurred during Spring, in highland areas dominated by secondary vegetation and agricultural activity.

Effects of habitat fragmentation on effective population size in the endangered Rio Grande silvery minnow

We assessed spatial and temporal patterns of genetic diversity to evaluate effects of river fragmentation on remnant populations of the federally endangered Rio Grande silvery minnow (Hybognathus amarus). Analysis of microsatellite and mitochondrial (mt) DNA detected little spatial genetic structure over the current geographic range, consistent with high gene flow despite fragmentation by dams....

Rio Grande Gummosis

Young Valencia orange trees were grown for three years in large outdoor sand cultures on complete nutrient solu tions that varied differentially only in the amount of boron. Three rates of boron were applied to single-tree plots. The plots were replicated four times. No difference in tree size resulted from the differential treatments. Rather large differences in the boron content of the leaves...

Rio Grande do Sul as published by Livraria do Globo : R egionalist temporalities and publishing ( 1924 - 1960 ) O Rio

In this article I intend to analyze the nexuses between the editorial project of Livraria do Globo, a publishing house of Porto Alegre, and gaúcho regionalism in Rio Grande do Sul in three temporalities: the heroic gauchismo of the 1920s; the critique and downward path of regionalism in the 1930s; and the return to themes and topics involving the South by local intelligentsia, with new criteria...
