Cette thèse porte sur la signification du paon et du phénix dans des contextes cultuels et funéraires, autour du Bassin méditerranéen entre le IVe et le XIIe siècle. L’étude est basée sur un corpus de 490 documents dans lesquels apparaissent un ou plusieurs paons, mis en parallèle avec 68 témoignages figurés du phénix. Ces oiseaux ont été mis en image de différentes manières et selon différents contextes, aussi bien sur des pièces de monnaie, des fresques catacombales, des sarcophages, des décors mosaïqués (pavements, coupoles, absides, …), des manuscrits ou bien encore sur des clôtures de chœur. L’observation des documents révèle que des liens ont été tissés entre les deux oiseaux associés tous deux à l’idée de renaissance bien avant le IVe siècle. En effet, la notion de renaissance est transversale dans l’étude de la figuration du paon et du phénix entre Antiquité et Moyen Âge, et entre paganisme et christianisme. Les premières références à ces deux oiseaux, connues dans les textes et l’iconographie antiques, ont été analysées afin de réfléchir sur l’imaginaire construit autour du paon et du phénix, liés aux rythmes cycliques, à la mort et à la résurrection. La fonction du paon comme psychopompe et plus largement comme intermédiaire entre terre et ciel et entre l’humain et le divin, s’affirme progressivement. Entre le IIIe et le IVe siècle, le paon et le phénix entrent dans le répertoire visuel funéraire des premiers chrétiens et commencent à être mis en relation avec la conception du baptême comme une renaissance. Entre le IVe et le VIe siècle, ils sont introduits dans l’espace ecclésial et resserrent leurs liens avec le Christ et le baptisé. Les deux oiseaux offrent au fidèle un espoir de salut en témoignant du triomphe du Christ sur la mort et en annonçant la résurrection des Élus. Entre le VIIe et le IXe siècle, la figuration du paon est notamment étudiée sur des clôtures de chœur et d’autres éléments de décors sculptés, en lien avec le rituel eucharistique, avec l’idée de passage entre charnel et spirituel. Le corpus réuni met en évidence le rôle du paon comme gardien du seuil, d’un point de vue matériel et spirituel. La présence récurrente du paon et du phénix entre le VIe et le IXe siècle dans des espaces ecclésiaux romains est également mise en perspective vis-à-vis des réalisations papales et selon des enjeux liés à la mémoire des saints et de l’Église. L’étude s’ouvre au XIIe siècle avec le décor monumental de Saint-Clément à Rome comme un témoignage charnière dans la signification du paon. / This dissertation deals with the meaning of the peacock and the phoenix within contexts of worship and funerary contexts in the Mediterranean area, between the IVth and the XIIth centuries. The study is based on an iconographic documentation meeting 490 items of the peacock and 68 items of the phoenix. These birds were imaged in various ways as well as coins, paintings of catacombs, sarcophagi, mosaics (pavements, domes, apses, …), manuscripts, and even chancel screens. The analysis of the documentation indicates that links were weaved between both birds associated with the idea of revival long before the IVth century. The idea of revival, indeed, is a cross-cutting concept in the study of the iconography of the peacock and the phoenix between Antiquity and Middle Ages, between paganism and christianity. The first references to the these birds in the antique texts and the iconography are studied in order to reflect on the imagination about the peacock and the phoenix, both associated with cyclic rhythms, death and resurrection. The peacock was seen as a psychopomp, more generally like an intermediary between earth and sky, as well as between the human and the divine. Between the IIIth and the IVth centuries, the peacock and the phoenix were inserted into the funerary iconography of the first Christians and begin to be linked with the conception of the baptism as a revival. Between the IVth and the VIth centuries, they were inserted into the ecclesial space and they tightened their links with the Christ and the baptized. The peacock and the phoenix offer to the believer a hope of being healed. They show the triumph of the Risen Christ and announce the resurrection of the dead at the end of days. Between the VIIth and the IXth centuries, the iconography of the peacock is studied in particular on chancel screens and on the other sculptures linked with the eucharistic rite and with the idea of a connection between caro and spiritus. The documentation highlights the role of the peacock as the guard of the threshold, from a material and spiritual point of view. The recurring presence of these birds between the VIth and the IXth centuries in Roman ecclesial spaces was also put in perspective towards the papal realizations and according to stakes strongly bound to the memory of the saints and the Church. The study opens to the XIIth century with San Clement’s monumental decoration in Rome as a pivotal testimony in the evolution of the meaning of the peacock.

La modélisation de la dynamique épidémiologique des ascomycètes parasites des arbres fruitiers présente deux aspects très importants : l’évaluation de la quantité d'inoculum et de son évolution, et l’identification des évènements climatiques donnant lieu à une contamination. Le travail présenté aborde ces deux aspects au travers de deux exemples : la tavelure du pommier, et la maladie de l’œil de paon de l’olivier, parasites majeurs pour les filières concernées.L’acquisition des connaissances sur la biologie des deux maladies a été abordée uniquement sur la base de données acquises sur le terrain, ce qui est original car généralement les modèles ont été réalisés sur la base de connaissances établies en conditions contrôlées.Dans le cas de Venturia inaequalis, agent de la tavelure du pommier, la vitesse de développement journalier de l’inoculum a été établie par optimisation numérique, sur la base d’observations réalisées en Provence. Un modèle de dynamique de projection des ascospores incluant la suspension de l’évolution de l’inoculum primaire lors des périodes sèches a été réalisé puis validé sur un jeu de données indépendantes. La transposabilité du modèle a été ensuite étudiée pour une autre région (Aquitaine). Dans le cas de Fusicladium oleagineum, agent de la maladie de l’oeil de paon, les conditions de contamination ont été établies en fonction de la température et de l’hygrométrie, d’une part par la réalisation d’un abaque sur la base de points sélectionnés par dires d’expert, et d’autre part de façon automatique à l’aide d’un système par apprentissage (réseau de neurones). Un modèle, liant la température moyenne après la contamination à l’apparition des symptômes a été ensuite réalisé. / Apple scab, caused by Venturia inaequalis, and peacoq leaf spot, cause by Fusicladiumoleagineum, are key diseases respectively for apple and olive growers. These disease usuallyrequire a large number of treatments. Adequate protection need a good evaluation ofquantitative disponibility of inoculum, and estimation of infection conditions.In this thesis, these two problems were studied using only field data. This is an originalaprroach to obtain knowledge about biology of fungi : most previous works were realised byregression of laboratory data obtained under controled conditions.In the case of Venturia inaequalis, primary inoculum consists of pseudothecia present in leaflitter. Treatments agains ascospore release period is the cornerstone of the strategy againstapple scab. However, the existing forecasting models are not reliable, and are all based ondegree-day time scale, proposed in 1982.Here, using a corpus of data acquired between 1996 and 2013, including observations ofascospore release and weather data, we assessed the daily rate of development of primaryinoculum by fitting generic new time scale functions. Further improvements were then studiedto take into account elements reported in litterature about the incidence of rain or wetness.Different methods were tested and adapted for the parameterisation of models by numericaloptimisation. Some forcasting models were proposed and adapted to the area where the studywas conducted, with parameters including rain and temperature. The validity was tested, andfurther developements of the forecasting tool was then proposed.In the case of Fusicladium oleagineum, a field-operational model predicting disease outbreakswas established as a function of temperature and relative humidity. First with the help ofpoints selected by experts, Secondly automaticaly using a neural network. A model defininglatent period as a function of average temperature after contamination was then realised.

Biometric fish and macro and microscopic classification of gonadal maturation data provided the basis for investigation of the following reproductive parameters: 1) the type of spawning for gonad morphology at each stage of development; 2) the reproductive period, through the time of gonadal maturation frequencies of gonadosomatic index (GSI) and condition factor (K1 and K2); 3) the existence of reproductive seasonality; 4) the size at first maturity (L50); 5) the size of which 100% of the population is able to play (L100); 6) the composition of the population in total length and sex ratio, and 7) the length-weight relationship of the specie. The results indicated parceled spawning and intense reproductive activity in all months of the year, with no reproductive seasonality. No differences in sex ratio over the year. There was sexual dimorphism in growth, with positive allometric growth of males and females negative allometric growth. Males had higher amplitudes in total length and weight than females, and sizes of first maturation (L50) higher than females, and 32 cm for males and 33.5 cm for females. The L100 was estimated at 33.4 cm for males and 34.2 cm for females. The variation in body condition represented by the allometric condition factor (K1) less somatic (K2), varied only for females, as well as variations of the gonadosomatic index (GSI) in different stages of gonadal development were significant only for females, both possibly due to the weight of the testes negligible when compared to the ovaries. There was no significant temporal variations in the IGS and K1 of males and females, possibly by mature individuals occur and emptied throughout the year. Variations in air temperature, accumulated rainfall and reservoir volume did not affect the reproductive activity, which may indicate reproductive success of Cichla piquiti in more variable environmental conditions. Still, continuous monitoring of the population would be needed as measures for management and preservation of the species in its original basin. / O objetivo deste trabalho foi analisar os aspectos da biologia reprodutiva de Cichla piquiti (Tucunaré-azul) no reservatório da Usina Hidrelétrica de Serra da Mesa, um ambiente de sua ocorrência natural (rio Tocantins, Goiás, Brasil). Foram amostrados 217 espécimes, sendo 109 fêmeas e 108 machos ao longo de um ciclo reprodutivo anual (outubro de 2012 a setembro de 2013) com o emprego de iscas artificiais. Os dados biométricos dos peixes e da classificação macro e microscópicas dos estádios de maturação gonadal embasaram a investigação dos seguintes parâmetros reprodutivos: 1) o tipo de desova, pela morfologia das gônadas em cada estádio de desenvolvimento; 2) o período reprodutivo, através das frequências temporais dos estádios de maturação gonadal, do Índice Gonadossomático (IGS) e do Fator de Condição (K1 e K2); 3) a existência de sazonalidade reprodutiva; 4) o tamanho da primeira maturação (L50); 5) o tamanho em que 100% da população está apta à reprodução (L100); 6) a composição da população em comprimento total e proporção sexual; e 7) a relação pesocomprimento da espécie. Os resultados indicaram desova parcelada e intensa atividade reprodutiva em todos os meses do ano, não havendo sazonalidade reprodutiva. Não houve diferenças na proporção sexual ao longo do ano. Houve dimorfismo sexual no crescimento, com crescimento alométrico positivo dos machos e crescimento alométrico negativo das fêmeas. Os machos apresentaram maiores amplitudes de comprimento total e peso que as fêmeas, além de tamanhos de primeira maturação gonadal (L50) mais elevados que as fêmeas, sendo 32 cm para machos e 33,5 cm para fêmeas. O L100 foi estimado em 33,4 cm para machos e 34,2 cm para fêmeas. A variação na condição corporal representada pelo Fator de Condição somático (K2) variou somente para as fêmeas, assim como as variações do Índice Gonadossomático (IGS) nos diferentes estádios de desenvolvimento gonadal, ambos possivelmente em função do peso desprezível dos testículos quando comparados aos ovários. Não houve variações temporais expressivas do Índice Gonadossomático (IGS) e do Fator de Condição total (K1) de machos e fêmeas, possivelmente pela presença de indivíduos maduros e esvaziados durante todo o ano. As variações da temperatura do ar, precipitação acumulada e volume do reservatório não afetaram a atividade reprodutiva, o que pode indicar sucesso reprodutivo de Cichla piquiti nas mais variáveis condições do ambiente. Ainda assim, monitoramentos contínuos da população seriam necessários para manejo e preservação da espécie em sua bacia original.

The behavior of this cichlid, which attacks lures, is especially exciting for anglers. The middle Negro River has become one of the most popular areas of sport fishing of the world, where the largest peacock bass can be found. The importance of catch-and-release fishing as an sustainable fishing strategy has been shown to directly help conserve peacock bass fish stocks in the region. In this study, peacock bass mortality was evaluated in relation to catch-and-release fishing, comparing two types of artificial lures: the jig and a traditional middle-water type. Fish, samples were collected in January/February and October/November of 2012 in the Unini River, a right margin tributary of the Negro River, in the municipal region of Barcelos in Amazonas State. A total of 191 peacock bass were caught, 90 by jig lure and the rest by the middle-water lure. Both fish groups were submitted to experimental confinement during a period of three days. In both groups, 30 fish were confined individually and 60 confined collectively. Additionally, 11 fish from the second group had radio transmitters attached to be used in telemetry. The mortality rate was calculated for each type of lure and type of confinement. No mortality was encountered for the group caught with a jig beat lure. In comparison, the middle-water lure showed a mortality rate of 1.66% for the collective confinement and 18.18% for the monitoring involving telemetry. For both types of lures, no mortality was observed for fish confined individually. The data was plotted using a Kruskal-Wallis variance analysis that showed values of X2 (1.179) = 0,502 and p= 0,478 for confined environments. The same test show values of X2 (1.179) = 1,005 e p= 0,316 for the different lures. The results indicated that neither confinement type or lure type had a significantly negative impact on the peacock bass mortality rate from the catch-and-release fishery, demonstrating that catchand- release fishing has a very small impact on peacock bass mortality. Therefore, this type of recreational fishing is beneficial as a strategy to help conserve peacock bass fish stocksfishery / A expansão da pesca amadora no Brasil teve inicio na década de 90 e tem alcançado os rios de água preta na região Amazônica, principalmente no médio Rio Negro onde são encontrados os grandes tucunarés (Cichla spp.). Com o acentuado crescimento desta atividade na região, a prática do pesque-solte vem sendo proposta como um procedimento sustentável na pesca esportiva dos tucunarés da região. Contudo, em face das dúvidas acerca da eficácia desta modalidade de pesca, avaliamos o efeito do pesque-solte sobre a sobrevivência do tucunaré, comparando dois tipos de iscas artificiais o jig e a meia-água. Foram realizados dois ensaios nos períodos de janeiro/fevereiro e outubro/novembro de 2012 no rio Unini, afluente da margem direita do rio Negro (Barcelos-AM). Em total foram capturados 191 tucunarés: 90 por iscas jig e os demais por iscas de meiaágua. Ambos os grupos de peixes foram submetidos a experimentos de confinamento por um período de 3 dias. Do primeiro grupo, 30 peixes foram confinados individualmente e 60 coletivamente. No segundo grupo, 30 foram confinados individualmente e 60 coletivamente. Adicionalmente, 11 peixes deste grupo foram marcados com transmissores de rádio para monitoramento por telemetria. A taxa de mortalidade foi calculada através do percentual dos indivíduos mortos para cada tipo de isca e ambiente de confinamento. Não houve mortalidade para o grupo de tucunaré capturado com jig. Por outro lado, a isca de meia-água apresentou taxa de mortalidade de 1,66% para o confinamento coletivo e de 18,18% para os monitorados por telemetria, não havendo, portanto mortes de indivíduos confinados individualmente. Estes dados foram analisados por meio de uma análise de variância Kruskal-Wallis, onde apresentaram valores de X2 (1.179) = 0,502 e p= 0,478 para os ambientes de confinamentos. O mesmo teste apresentou valores de X2 (1.179) = 1,005 e p= 0,316 para as iscas utilizadas. Dessa forma, os resultados indicam que ambos, o tipo de ambiente e o tipo de isca, não apresentaram influencia significativa sobre a taxa de mortalidade dos tucunarés na prática do pesque-solte. Estes resultados mostram que a prática desta modalidade de pesca amadora, resulta em baixa taxa de mortalidade para os tucunarés. Sendo assim o pesque-solte se mostra uma atividade que não prejudica a sustentabilidade dos estoques pesqueiros de tucunaré.

This thesis examines the status of caricature in the literary culture of early-nineteenth- century Britain, with a focus on the novel. It shows how the early-nineteenth- century novel developed a variety of literary forms that negotiated and remade caricature for the bourgeois literary sphere. Case studies are drawn primarily from the published writings and manuscript drafts of Thomas Love Peacock, Jane Austen, Mary Shelley, and Walter Scott. The first chapter elucidates the various meanings and uses of 'caricature' in the eighteenth and early nineteenth centuries, when the term was more ambiguous and broadly applied than literary criticism and print history have acknowledged. I counter the assumption that the single-sheet satirical print was central to conceptions and practices of caricature in this period, giving examples of the textual, dramatic, and real-life 'caricatures' that were more often under discussion. The second and third chapters consider the unstable distinction between textual caricature and satirical characterisation in early-nineteenth-century literary culture. They explain how the literary construction of textual caricature developed from two sources: Augustan rulings against publishing satires on individuals, and caricature portraits as a pastime beloved of genteel British society. I argue that Peacock and Austen adapted forms of 'caricaturistic writing' that were conscious of the satirical literary work's relation to caricature. Subsequent chapters turn to the thematic uses of caricature in the early-nineteenth- century novel. In the fourth chapter, I uncover the significance of caricature to deformity in Mary Shelley's fiction, presenting evidence that her monsters' disproportion was inherited from the 'real-life' caricatures diagnosed in philosophical and medical texts of the eighteenth century. The final chapter traces ideas about caricature through the writings of Walter Scott, and finds that Scott conceived of exemplary graphic and textual caricatures as artefacts of antiquarian interest.
