Given the fast advance of Eucalyptus silviculture over grassland areas in this biome, and the scant knowledge on the soil spider fauna in these landscapes, we aimed to provide a first view of spiders occurring there and to quantitatively evaluate differences in the spider fauna between the two environments. Study areas included five farms each with the two environments, native grassland and Eucalyptus plantation. Spider densities were 6.53 (±1.01s.e.) individuals/m-2 in silviculture and 3.88 individuals/m-2 (±0.73) in grassland. This could be due to spiders finding more shelter sites underneath a denser silviculture litter than in the grassland where they could be more exposed, for example, to their own predators. Twentyfour spider families were captured; the most abundant and diverse were Salticidae and Linyphiidae. Nineteen families occurred in the silviculture and 21 in the grassland. For adult spiders...

Varias criticas sao feitas ao atual padrao de ensino, frequentemente rotulado como um modelo mecanicista, centrado no aprendizado passivo. O presente trabalho objetiva fazer um apanhado destes questionamentos para, no primeiro momento, compreender a gravidade da situacao e, em seguida, embasar a busca de caminhos que proporcionem uma ressignificacao do sistema educacional brasileiro, a fim de formarmos alunos melhores qualificados para o mercado de trabalho e mais completos como seres humanos. Esta pesquisa e um ensaio teorico de natureza descritiva-exploratoria, apoiada na investigacao bibliografica. O estudo em questao nao tem a pretensao de encontrar solucoes para os problemas identificados, mas, espera-se gerar debates e estimular a realizacao de pesquisas mais aprofundadas.

We propose a new diagnosis, redescribe the type species, and propose a new synonymy and a new combination. In addition, a male-based key to both species recognized, including Erythrocricus electrofasciatus (Schubart, 1957), comb. nov. ex. Rhinocricus, is given.

In thiswork we describe and illustrate five new species of Rhinocricus from Rio Grande do Sul: R. itauba sp. nov., R. gauchussp. nov., R. guaritas sp. nov., and R. serranus sp. nov., described from specimens of both sexes, and R. vacariensis sp. nov.based on a single male. The species R. divaricatus, R. padbergi and R. serratus are registered for the first time for this state. A key to Rio Grande do Sul species is presented.

Sixty-five araneid species from 20 genera were collected during an inventory of riparian forests in southern Brazil. Among these were one new species, described here as Mangora piratini sp. nov. Also discovered were the previously unknown males of Alpaida citrina (Keyserling, 1893), A. octolobata Levi, 1988 and Testudinaria lemniscata (Simon, 1895), which are described here for the first time. Metazygia floresta Levi, 1995, Ocrepeira malleri Levi, 1993 and Testudinaria quadripunctata Taczanowski, 1879 are recorded for the first time for Rio Grande do Sul State, Brazil.

L. laeta (Nicolet, 1849) and L. intermedia MelloLeitão, 1934 were the collected species. L. intermedia was the most numerous specie. In Pelotas many specimens were collected, over old books, newspapers and paper leaves. In comparasion to previous papers, some morphological variations were observed in this two species: in L. intermedia the length of legs is much larger than the specie general pathern; in L. laeta the same feature do not occur but the long length of male s palp is very conspicuous.

New synonymies proposed: Chrysso ribeirao Levi, 1962 and C. caraca Levi, 1962 with Chrysso arops Levi, 1962; Cryptachaea diamantina (Levi, 1963) with C. hirta (Taczanowski, 1873) and Cryptachaea maxima (Keyserling, 1884) with C. altiventer (Keyserling, 1884). Theridion altum Levi, 1963 is considered as a new synonym of Theridion soaresi Levi, 1963. Theridion melanosternum Mello-Leitão, 1947 is synonymized with Oedothorax bisignatus Mello-Leitão, 1944 and this species is removed from the synonymy with Theridion calcynatum Holmberg, 1876 and transferred to Theridion Walckenaer, 1805. Theridion tungurahua Levi, 1963 is the female of Theridion fungosum Keyserlin...

Several studies demonstrate that changes in vegetation surrounding rivers, streams and brooks affect the associated araneofauna. The aim of this research was to compare differences found in diversity (abundance and richness), composition and phenology of Araneidae spiders sampled in different habitats in four riparian forest catchments in southern Brazil. Samples were taken from riparian forests in four rivers of Rio Grande do Sul State: Piratini, Camaquã, Sinos and Maquiné rivers, each in a different hydrographic basin. Samples were taken twice seasonally on each basin during two years, sampling the araneofauna of the tree-shrub strata with beating tray. Six transects were employed on each basin, two per habitat: edge with grassland, forest interior and river edge. Araneids totalled 20 genera and 65 species. Comparing riparian forests significant differences a...
