Camponeses Brazil's Peasant Movement in Historical Perspective (1946-2004)

Comparison of the histories of three leading peasant organizations in the Pontal do Paranapanema region of Brazil-the Partido Comunista do Brasil (PCB) from 1945 to 1964, the Confederacao Nacional de Trabalhadores na Agricultura (CONTAG) from 1964 to 1984, and the Movimento dos Trabalhadores Rurais Sem-Terra (MST) from 1984 to 2004-suggests that continuity is as important as change in understanding Brazilian peasant movements. The MST has been considered a "new social movement" in that it has eschewed partisan politics, incorporated families as members rather than just male heads of household, had a national scope and a participatory decision-making structure, and been attuned to the international struggle over globalization. Placing it in historical perspective makes it clear, however, that this is not the first time that militants have organized around the concept of peasants as a political identity; that while the representation of peasants in the leadership of contemporary rural labor organizations may be greater than in the past, earlier peasant leaders also struggled on behalf of their class; that earlier peasant organizations had, if not a national presence, a substantial presence in the agricultural states of the time; and that attempts at international organization to unite peasant struggles around the globe are not entirely new. This is not to deny the innovative features of contemporary movements but to suggest that the investigation of past achievements will contribute to a fuller appreciation of these movements' conditions and prospects.

Phylogenetic analysis of the Neotropical social wasps of the genus Angiopolybia Araujo, 1946 (Hymenoptera, Vespidae, Epiponini)

A morphological cladistic analysis of the Neotropical swarm-founding genus Angiopolybia Araujo is presented. A single cladogram resulted from the analysis, with the following ingroup topology: (A. pallens + A. zischkai) + (A. paraensis + A. obidensis). The monophyly of the genus is supported by four synapomorphies. A new identification key is presented for the genus. Copyright © 2007 Magnolia Press.

A new species of Hemigrammus Gill, 1858 (Characiformes: Characidae) from Río Caura, Venezuela

A new characid species, Hemigrammus taphorni, is described from the Río Caura drainage, Venezuela. The new species is distinguished from its congeners by characters related to its color pattern, number of scale rows below the lateral line, teeth morphology, and dorsal-fin length. A brief discussion about the putative relationships of H. taphorni is provided. Copyright © 2007 Magnolia Press.

Alimentação de Serrasalmus maculatus (Kner, 1858) (characiformes; serrasalmidae) no trecho inferior bacia do rio Sorocaba, São Paulo, Brasil

The aim of this study was to discuss aspects of the diet of Serrasalmus maculatus. Fish were collected using gill nets, whose lengths measured 100 m and mesh diameters varied from 3 to 8 cm. A total of 107 individuals were collected. Their length varied from 62 to 210 mm. They were mainly represented by female and immature individuals. No individual was caught in temperatures below 21°C. Four feeding item categories were observed: fish muscle pieces, parts of fish fins, plant fragments, and insects. Comparisons made among individual length classes revealed some significant differences within stomach consumed contents. Individuals whose length exceeded 165 mm consumed only parts of fish muscles and plants. The food availability in the environment and the class lengths amplitude may, however, have influenced the results, in which ontogenetic differences should not be precisely observed.

The present note reports the first record for Brazil of the cicada Zammara smaragdula Walker, 1858 (Hemiptera, Cicadidae, Zammarini). This new record brings the number of reported Cicadidae species for Brazil to 153, including three species in the genus Zammara. © 2011 Check List and Authors.

Division of labor in pachycondyla striata Fr. Smith, 1858 (Hymenoptera: Formicidae: Ponerinae)

Four colonies of the ant Pachycondyla striata were used to analyze the specie behavioral repertoire. Forty-six behavioral acts were recorded in laboratory. Here, we present the record the division of labor between the castes and the temporal polyethism of monomorphic workers. The queens carried out many of the behavioral traits recorded in this work however; they performed them less frequently compared to the worker. The workers activity involved chasing and feeding on fresh insects and usingthem to nourish larvae besides laying eggs in the C-posture, an activity also performed by queens, which is similar to that of wasps of the subfamily Stenogastrinae. The young workers were involved in activities of brood care, sexuate care, and nest maintenance, and the older workers were involved in defense, exploration, and foraging. © 2012 Adolfo da Silva-Melo and Edilberto Giannotti.
