Chaunus ictericus (Spix, 1824) as paratenic host of the giant kidney worm Dioctophyme renale (Goeze, 1782) (Nematoda: Enoplida) in Sao Cristovao district, Tres Barras county, Santa Catarina state, Brazil

Dioctophyme renale larvae have been found in cysts in the gastric wall of 5.17% (3/58) Chaunus ictericus specimens from Sao Cristovao district, Tres Barras municipality, Santa Catarina state, Brazil. However, larvae of this nematode were not found in sympatric Chaunus schneideri. The larvae caused a mild granulomatous reaction. This is the first report of paratenic hosts for D. renale in Brazil, and probably is also the first in the Neotropical region. (C) 2009 Elsevier B.V. All rights reserved.

Cladistic analysis of the suborder Conulariina Miller and Gurley, 1896 (Cnidaria, Scyphozoa; Vendian-Triassic)

Results of a cladistic analysis of the suborder Conulariina Miller and Gurley, 1896, a major extinct (Vendian-Triassic) group of scyphozoan cnidarians, are presented. The analysis sought to test whether the three conulariid subfamilies (Conulariinae Walcott, 1886, Paraconulariinae Sinclair, 1952 and Ctenoconulariinae Sinclair, 1952) recognized in the Treatise on Invertebrate Paleontology ( TIP) are monophyletic. A total of 17 morphological characters were scored for 16 ingroup taxa, namely the genera Archaeoconularia, Baccaconularia, Climacoconus, Conularia, Conulariella, Conularina, Ctenoconularia, Eoconularia, Glyptoconularia, Metaconularia, Notoconularia, Paraconularia, Pseudoconularia, Reticulaconularia, Teresconularia and Vendoconularia. The extant medusozoan taxa Cubozoa, Stauromedusae, Coronatae and Semaeostomeae served as outgroups. Unweighted analysisof the data matrix yielded 1057 trees, and successive weighting analysis resulted in one of the 1057 original trees. The ingroup is monophyletic with two autapomorphies: (1) the quadrate geometry of the oral region; and (2) the presence of a mineralized (phosphatic) periderm. Within the ingroup, the clade (Vendoconularia, Teresconularia, Conularina, Eoconularia) is supported by the sinusoidal longitudinal geometry of the transverse ridges, and the much larger clade (Baccaconularia, Glyptoconularia, Metaconularia, Pseudoconularia, Conularia, Ctenoconularia, Archaeoconularia, Notoconularia, Climacoconus, Paraconularia, Reticulaconularia) is supported by the presence of external tubercles, which, however, were lost in the clade (Notoconularia, Climacoconus, Paraconularia, Reticulaconularia). As proposed by Van Iten et al. (2000), the clade (Notoconularia, Climacoconus, Paraconularia, Reticulaconularia) is supported by the termination and alternation of the transverse ribs in the corner sulcus. The previously recognized subfamilies Conulariinae, Paraconulariinae and Ctenoconulariinae were not recovered from this analysis. The diagnostic features of Conulariinae (continuation of the transverse ornament across the corner sulcus and lack of carinae) and Ctenoconulariinae ( presence of carinae) are symplesiomorphic or homoplastic, and Paraconulariinae is polyphyletic. The families Conulariellidae Kiderlen, 1937 and Conulariopsidae Sugiyama, 1942, also recognized in the TIP, are monogeneric, and since they provide no additional phylogenetic information, should be abandoned.

On the identity of Hyla strigilata Spix, 1824 (Anura : Hylidae): redescription and neotype designation for a ghost taxon

Recent field work in Atlantic Rain Forest patches in the southern region of the State of Bahia, Brazil, resulted in the discovery of some populations of an unidentified species of the Scinax catharinae group. An extensive literature review, along with the examination of specimens and distribution patterns of all known species of this group, showed that Hyla strigilata Spix, 1824, a long confused species with lost type material, is an available name for the specimens from Bahia. In order to clarify the taxonomic problems surrounding this taxon, the nomenclatural history of Hyla strigilata is reviewed and a neotype is designated, described, and figured. The association of this name to extant populations from southern Bahia and its consequent stabilization is considered important since it is the type species of the genus Ololygon, a name available for the clade of Scinax catharinae. Data on habits, habitat, and geographic distribution are also presented.

Whitham method for the Benjamin-Ono-Burgers equation and dispersive shocks

The Whitham modulation equations for the parameters of a periodic solution are derived using the generalized Lagrangian approach for the case of the damped Benjamin-Ono equation. The structure of the dispersive shock is considered in this method.

Short-wave instabilities in the Benjamin-Bona-Mahoney-Peregrine equation: theory and numerics

In this paper we discuss the nonlinear propagation of waves of short wavelength in dispersive systems. We propose a family of equations that is likely to describe the asymptotic behaviour of a large class of systems. We then restrict our attention to the analysis of the simplest nonlinear short-wave dynamics given by U-0 xi tau, = U-0 - 3(U-0)(2). We integrate numerically this equation for periodic and non-periodic boundary conditions, and we find that short waves may exist only if the amplitude of the initial profile is not too large.

Análise populacional de colônias de Polybia (Myrapetra) paulista (Ihering, 1896) (Hymenoptera, Vespidae)

The data suggest that Polybia (Myrapetra) paulista colonies are established by means of swarm formation having the existence of an initial polygyny and a pleometrose being proved. The reproductive forms are produced once a year (at the start of the year); however, the colonies can last for two or three years. The observations evidenced that the duration of a development period is about 100 days.

Notas sobre Siegfried Kracauer, Walter Benjamin e a Paris do Segundo Império: pontos de contato

Trata-se de mostrar a originalidade crítica de Siegfried Kracauer diante da experiência da modernidade estética e de discutir as afinidades estético-teóricas de Kracauer e Benjamim ao analisar a Paris da segunda metade do século XIX, o Segundo Império, em particular, como fenômeno originário da sociedade de massas, da indústria cultural e do entretenimento e, sobretudo, do nazi-fascismo. Kracauer durante seu exílio parisiense (1933-41) escreveu uma biografia da sociedade: Jacques Offenbach e a Paris de sua época (Jacques Offenbach und das Paris seiner Zeit). Obra inovadora pelo seu enfoque da história do presente e com pontos de contatos com a Obra das Passagens (Passagen-Werk) ou Paris capital do século XIX de Walter Benjamin.

Retrato policial: um perfil da praça de polícia em São Paulo (1868-1896)

O objetivo deste artigo é apresentar um perfil das praças que cerraram fileira na polícia de São Paulo entre 1868 e 1896. A partir de dados biográficos - altura, idade, local de nascimento, cor da pele, ofício anterior, situação familiar - buscamos identificar, na base da pirâmide hierárquica, pistas sobre o processo de formação do aparato policial paulista; ao mesmo tempo em que pretendemos traçar um recorte da população - pobre e masculina - num período de crise do escravismo, de inflexão do sistema de mão-de-obra, de incorporação de um importante contingente estrangeiro, e de mudança do paradigma político no país.

Metacercariae of Diplostomum compactum Lutz, 1928 (Trematoda, Diplostomidae) in the eyes of acara Geophagus brasiliensis Quoy & Gaimard, 1824 (Teleostei, Cichlidae) from Barra Bonita Reservoir - São Paulo, Brazil

Relata-se a ocorrência de metacercárias de Diplostomum compactum (Trematoda: Diplostomidae) infectando Geophagus brasiliensis (Teleostei: Cichlidae) do reservatório de Barra Bonita, rio Tietê, estado de São Paulo, Brasil. As metacercárias foram coletadas no globo ocular, fixadas em solução de AFA e coradas com carmim. As análises morfológicas e morfométricas de cinco espécimes foram realizadas por meio do sistema computadorizado de analise de imagem. Este foi o primeiro registro da ocorrência desse parasito no reservatório de Barra Bonita e também o primeiro registro em acará Geophagus brasiliensis.

Avaliação da qualidade de frutos de café atacados por Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae)

Foram usadas plantas de Coffea arabica L., variedade Catuaí Vermelho, localizadas no Campus da Escola Superior de Agricultura Luiz de Queiroz - USP, Piracicaba,SP, para avaliação dos danos que Ceratitis capitata (Wied., 1824) pode causar aos frutos do cafeeiro. Os resultados mostraram que o ataque de C. capitula não causou queda prematura dos frutos, mas aumentou a queda de cerejas e foram encontradas, fortes evidências, com base na atividade da enzima polifenol oxidase e lixiviação de potássio, que cerejas atacadas podem produzir bebida de café de qualidade inferior.
