In four stretches of the river, we sampled species quarterly between April/2008 and June/2009 using five traps (minnow-traps) and four sessions with gillnet. We selected sixteen species for the analyses which were present in all sampled points. We constructed a functional matrix for each descriptor considering relative abundance data (%). For each matrix we performed a nonparametric analysis (Kruskal-Wallis) followed by a post hoc analysis (multiple analyses) to verify if there are differences between the four sampling points of the river. We realized a Spearman correlation analysis between each matrix and the river width and, then, a Principal Component Analyses (PCA) to verify if sampling points could be ordered by the functional descriptors. All analyses above were performed using the software Statistica 7. We tested temporal synchrony of the functional descriptors using each functional matrix for a multiple co-inertia analysis (ACOM). These analyses were performed in software ADE-4. Differences between four points sampled were higher than expected by chance for trophic guild and length classes (p<0,0001 for both descriptors). Our post hoc analysis indicated differences higher than expected by chance between points P3 and P4 for trophic guild (p <0,01) and length classes (p<0,001), however, these differences are not correlated with river width. PCA analyses demonstrated that species from length class A (71,22%) and omnivores (30%) were more associated with point P4 while iliophagous fishes (56,17%) and those belonging to length class B (53,64%) are more associated with point P2. ACOM results demonstrated that points P2 (COS2 = 6,425 e 01; COV2 = 4,654 e + 00; RV = 0,82) and P3 (COS2 = 8,156 e - 01; COV2 = 3,186 e + 00; RV = 0,87) have a variation in their temporal pattern similar for what is expected for trophic guild and have a better synchrony. In the case of length classes, points P3 (RV = 0,82) and P4 (RV = 0,81) presents a better synchrony. Starting from the fifth sampling (January), we observed changes in the synchrony of functional descriptors. Spatial and temporal patterns of distribution from fish assemblages in Veríssimo river seems to reflect seasonality and the migratory behavior of the species Steindachnerina insculpta. / O objetivo principal deste estudo foi testar se as assembleias de peixes ao longo do rio Veríssimo variavam espacialmente e temporalmente em relação aos descritores funcionais guilda trófica e classes de tamanho. Em quatro trechos do rio, coletamos as espécies trimestralmente entre Abril/2008 e Junho/2009 utilizando cinco armadilhas (minnow-traps) e quatro sessões com rede de emalhar. Selecionamos dezesseis espécies para as análises, as quais estavam presentes em todos os pontos amostrais. Construímos uma matriz de dados para cada descritor funcional considerando os dados de abundância relativa (%). Para cada matriz conduzimos uma análise não-paramétrica (Kruskal-Wallis) seguida de uma análise post hoc (múltiplas análises) com o objetivo de verificar se há diferenças entre os quatro trechos amostrados. Realizamos uma análise de correlação de Spearman entre cada matriz e a largura do rio e, em seguida, uma Análise de Componentes Principais (em inglês PCA) com cada matriz para verificar se os pontos amostrados poderiam ser ordenados pelos descritores funcionais. As análises acima descritas foram feitas no programa Statistica 7. Testamos a sincronia temporal dos descritores funcionais usando cada matriz em uma análise de co-inércia múltipla (ACOM). Estas análises foram feitas no programa ADE-4. As diferenças entre os quatro pontos de amostragem foram maior do que o esperado ao acaso para guilda trófica e classes de tamanho (em ambos os casos p<0,001). Nossa análise post hoc indicou diferenças maiores do que o esperado entre os pontos amostrais P3 e P4 para guilda trófica (p <0,01) e classes de tamanho (p<0,001), entretanto, elas não estavam correlacionadas com a largura do rio. A PCA indicou que os peixes onívoros (30%) e da classe de tamanho A (71,22%) estavam mais associados ao ponto P4, enquanto os peixes iliófagos (56,17%) e da classe de tamanho B (53,64%) com o ponto P2. Os resultados da ACOM demonstraram os pontos P2 (COS2 = 6,425 e 01; COV2 = 4,654 e + 00; RV = 0,82) e P3 (COS2 = 8,156 e - 01; COV2 = 3,186 e + 00; RV = 0,87) possuem um padrão de variação temporal similar ao que seria esperado para guilda trófica. Para as classes de tamanho os pontos P3 (RV = 0,82) e P4 (RV = 0,81) apresentam uma melhor sincronia. A partir da quinta coleta (Janeiro), percebemos mudanças na sincronia dos descritores funcionais. Os padrões espaciais e temporais de distribuição das assembleias de peixes no rio Veríssimo parecem refletir a sazonalidade e o habito migratório da espécie Steindachnerina insculpta.

Neste sentido o objetivo deste estudo é a caracterização trófica de espécies de peixes de cabeceira de arroios subtropicais e a identificação do fluxo de energia entre macroinvertebrados e peixes. Espera-se que a biomassa de peixes detritívoros aumente conforme o gradiente longitudinal, devido ao aumento da produção primaria neste sentido. O estudo foi desenvolvido em 32 sítios de 1ª a 4ª ordem pertencentes a oito microbacias da Bacia do Rio dos Sinos. As coletas de ictiofauna foram realizadas utilizando pesca elétrica em uma área de 100m2. Macroinvertebrados foram coletados com amostrador Surber, para avaliar a disponibilidade de recurso e biomassa de consumidores primários. A riqueza e a diversidade da comunidade íctica foram calculadas. Foi avaliada a dieta das espécies de peixes mais abundantes e calculados os índices de importância relativa e de amplitude de nicho. Para verificar a transferência de energia entre consumidores primários e secundários foi quantificada a biomassa seca de peixes e macroinvertebrados. Os resultados demonstram que a diversidade, a riqueza e a biomassa aumentaram conforme o gradiente longitudinal que arroios de cabeceira, corroborando as previsões do RCC. Também constatou-se que a comunidade íctica é composta por duas guildas alimentares (insetívoros e detritívoros). Estes últimos, por sua vez, elevaram a biomassa íctica e estabeleceram duas vias de fluxo de energia atuando como consumidores primários e secundários. / The River Continuum Concept (RCC) suggests that changes in physico-chemical factors across the stream longitudinal gradient leads to the adding of species of different feeding habits. In this sense, the aim of the study is the trophic characterization of fish headwater species from subtropical streams and to identify energy flow between macroinvertebrate and fishes. It is expected that detritivorous fish standing crop increase across stream longitudinal gradient due to increase in primary production in the same direction. This study was carried out in 32 streams from 1st to 4thorder in eight microbasins in the Sinos River basin. Ichthyofauna was sampled with electric fishing in 100m2 sections. Macroinvertebrates were sampled with Surber sampler to assess resource availability and primary consumer standing crop. Richness and diversity of fish communities were also calculated. The diet of the most abundant fish species was assessed as well as relative importance and niche amplitude indexes. The results displayed that fish diversity, richness and standing crop increased across stream longitudinal gradient corroborating RCC postulates. It was also indicated that fish communities was composed by two feeding groups (insetivorous and detritivorous). The detritivorous fishes have in turn increased fish standing crop and established two directions of energy flow which act as both primary and secondary consumers.

The French baroque petit motet was the most prolific genre of seventeenth-century France. In this study, three petits motets, specifically Regina caeli settings of French composers Marc-Antoine Charpentier, Nicolas Bernier and François Couperin are examined with an emphasis on the motets’ historical context in relation to the French monarchy and the Italian concepts that the composers incorporated into each work. All three Regina caeli settings display some Italian compositional techniques of the stile moderno in various degrees and were written in different contextual ecclesiastic milieux. The intersections of, as well as distinctions between, musical ideas of traditional French style and Italian innovations was at the center of music and musical discourse during the baroque period. The French were introduced to Italian style by travelling musicians at the court of France; however, when Louis XIV gave Jean-Baptiste Lully the important position of surintendant de la musique, the idea of an authentic unaltered French sound became prevalent among musicians and critics. Lully, strongest defender of “pure” French style, created a strict environment for musicians at court, and only after his death, did composers gain in freedom. The study suggests that a closer association to Louis XIV permitted musicians to integrate more of the Italian stile moderno techniques than those who did not have this opportunity. Crucial figures of the French monarchy, Louis XIV, Philippe II d’Orléans and the duc de Bourgogne were connected to the three composers central to this project and impacted the outcome of their work. With the musical-historical study of three Regina caeli settings, this project demonstrates the importance of the petit motet genre within the repertoire and the need for additional research to increase the accessibility of this inestimable music

Auteur de nombreux recueils poétiques depuis 1978, Jean-Michel Maulpoix apparaît comme l’un des poètes majeurs de sa génération, dont il est également un défenseur et un théoricien. Si sa poésie se veut pleinement de son temps, dont elle partage les doutes, les inquiétudes et les malaises, elle tente cependant, sans pour autant effacer toute marque personnelle, de porter ceux-ci à une dimension universelle, tout en se montrant tendue vers un idéal d’apaisement. Cette étude, qui conjugue une analyse thématique à des commentaires stylistiques parfois appuyés sur des décomptes statistiques, tente ainsi de montrer que cette tension entre dissonance et apaisement travaille profondément l’écriture des différents recueils, dans leurs thèmes comme dans leur forme, leur énonciation et leur rythme. Elle emprunte à la musique les notions de « basse obstinée » et de « basse continue », non pour suggérer que la poésie soit analysable en termes musicaux, mais en tant que métaphores d’une écriture elle-même obstinée, qui privilégie la continuité plutôt que les ruptures, et une continuité qui n’exclut pas la variation, jusque dans le rythme des phrases et des poèmes. / Author of many collections of poems since 1978, Jean-Michel Maulpoix is one of the most important poets of his generation. He is also known as a theoretician. His poetry is influenced by our times, and it shares its doubts and uneasiness. But the poet also gives an universal dimension to his poems, even if all marks of subjectivity are not erased. The poems often seem to search an ideal of appeasement. This dissertation analyses both themes and style : it aims at showing that this tension between uneasiness and appeasement is very important in many collections of poems by Jean-Michel Maulpoix, in their themes, form, enunciation, and rhythm. It uses the musical concepts of “basso ostinato” and “basso continuo”, not to suggest a confusion between poetry and music, but as metaphors of the obstinacy of the writing itself. The poems by Jean-Michel Maulpoix prefer continuity to ruptures, a kind of continuity that does not exclude variation, even into the rhythm of sentences and poems.

Heinrich Ignaz Franz von Biber's (1644--1704) Mystery Sonatas of 1676 are a set of fifteen sonatas for violin and continuo plus one unaccompanied passacaglia for solo violin. They are unusual in their use of scordatura and in the presence of an image associated with the Rosary devotion before each sonata. This association between image and music in the sonatas, and the correspondence to the fifteen mysteries of the Rosary closely resembles the structure of seventeenth-century Rosary picture books. / In this thesis the context, background, and meaning of the sonatas is explored. The first chapter examines the function of the sonatas and places them in context by outlining musical life in Salzburg, the sonata tradition, the Rosary devotion, Emblem books, and Rosary picture books. The second chapter focuses more on the collection as a whole and on elements such as key, dance affect, and scordatura. The third chapter consists of an examination of three sonatas---each one unique in placing the listener in a different relation to the mystery.

Die Kantate »La bella fiamma ò Tirsi« gehört zu den wenigen Werken aus einem umfangreichen OEuvre von 63 Kammerkantaten von Johann David Heinichen, deren Entstehungsort und Datierung überliefert sind: »Venetiis. Kal:X.Sept: 1711«. Die Herkunft des Textes ist noch ungeklärt. Er entspricht aber der verbreiteten italienischen Barocklyrik, die seelische Konflikte wie Liebeskummer zumeist metaphorisch in Naturbildern ausspricht. Diese Kantaten gaben offenbar den Ausschlag, dass der Kurprinz, nachdem er die Genehmigung hierfür bei seinem Vater Friedrich August I. aus Dresden eingeholt hatte, Heinichen als sächsischen Hofkapellmeister ab dem 1. August 1716 verpflichte. Zum Geburtstag des Kurprinzen am 17. Oktober 1716 komponierte Heinichen eine Serenata, welche die Musiker in Gondeln auf dem Canale grande aufführten.
