West, John Peter. "Dryden and enthusiasm." Thesis, University of Warwick, 2011. http://wrap.warwick.ac.uk/51566/.
Full textAbstract:
This thesis interprets the work of John Dryden in the context of the cultural, political and religious controversy that surrounded the concept of "enthusiasm" in later seventeenth-century England. It argues that Dryden is a more "enthusiastic" writer than is commonly thought, both in terms of poetics and of epistemology. It examines the tensions inherent in this enthusiasm when it is placed in the context of contemporary anxieties surrounding religious dissent and the memories of mid-century radicalism. Chapter One explores how "fancy", commonly a cultural signifier for fanaticism, was important in the formulation of an idea of poetic enthusiasm in Dryden's early critical works. In seeking to represent things beyond nature, this model of enthusiasm was underpinned by a concern that marvellous fiction could be mistaken for truth. Chapter Two pursues these ideas into the period of Plot and Exclusion. Dryden responded to a changed political culture with a renewed prioritisation of judgement, but the chapter will show how he sought to retain some aspects of his "enthusiastic" style. Chapter Three discusses Dryden's use of the later seventeenth-century Pindaric ode, a form in which cultural debates about religious enthusiasm and poetic inspiration took place. Chapter Four investigates Dryden's understanding of providence in some of his late work and considers how the mysteries of the divine, that had previously been a source of literary inspiration, began to suggest suffering after the political losses of 1688. As well as positing a revised view of Dryden as an imaginative writer, then, this thesis suggests ways in which the relationship between politics and literature in the later seventeenth century was less oppositional and more a fluid process of contest for, and appropriation of, key ideas. It also outlines Dryden's place in a larger narrative of the development of poetic "enthusiasm" in the eighteenth century.

Full textAbstract:
Centree sur la poesie satirique de dryden, dont sont soulignees la polysemie fondamentale et l'ambiguite, mais prenant en compte l'ensemble tres vaste de son oeuvre, cette etude se situe dans une perspective a la fois historique et stylistique, voire linguistique. L'ecrivain a ete associe a divers milieux sociaux et a vecu dans une periode de tensions que refletent ses poemes, ses pieces de theatre, ses essais de critique litteraire et ses textes polemiques. Quant a sa vision du monde, elle apparait constituee de courants de pensee mouvants et divergents, et meme contradictoires, comme le manifestent ses idees religieuses, scientifiques, historiques, politiques et litteraires envisagees tour a tour. Si le penchant de dryden pour l'argumentation et son gout pour certaines formes reductrices (au plan de la rhetorique ou des images) favorisent l'expression satirique, son ecriture ne cesse de s'enrichir d'allusions culturelles et de resonances (grace en particulier a une parfaite maitrise de la langue et de la prosodie). Ainsi satire et poesie se trouvent intimement liees et leurs incidences reciproques et volontiers paradoxales sont analysees dans les prologues et les epilogues, dans mac flecknoe, dans absalom and achitophel, dans the medall et dans the hind and the panther. L'ironie, tributaire notamment d'une certaine polyphonie enonciative et de jongleries et creations verbales, en vient a etre intensifiee mais aussi perturbee par les effets poetiquesFocussed on dryden's satirical poetry whose fundamental ambivalence and ambiguity are stressed, but also taking into account his whole extensive work, this study develops along a historical and stylistic (if not linguistic) line. Our author was connected with various social classes and lived in a period of tensions mirrored in his poems, his plays, his critical essays and his polemical writings, while his vision of the world integrates moving and diverging, even contradictory, ideas, as is revealed in his religious, scientific, historical, political and literary views. If dryden's keen expertise in argumentation and his fondness for rhetorical and stylistic reductions are conducive to satire, his writing is ceaselessly enriched by cultural allusions and resonance (thanks in particular to a perfect mastery of language and prosody). Thus satire and poetry are shown to be intimately and intricately associated and their often paradoxical relationship is analysed in the prologues and epilogues, mac flecknoe, absalom and achitophel, the medall and the hind and the panther. Irony, which tends to be linked with a form of enunciative polyphony, with plays on words and verbal creations, is both intensified and blurred, even subverted, by poetry

Clingham, G. J. H. "Johnson on Dryden and Pope." Thesis, University of Cambridge, 1986. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.232978.
Full textAbstract:
This work argues that a misunderstanding of the structure and content of Johnson's literary biography has prevented us from seeing that the Lives of Dryden and Pope are profound and challenging criticism. Inappropriate generic and historical criteria have been imposed on the Lives of the Poets so that the relation between biography and criticism has falsely been seen as discontinuous, and, concomitantly, Johnson's central, animating critical value of Nature has been defined solely in terms of neoclassical formalism, or, at best, associated with psychological value. As a preliminary to a discussion of the Lives of Dryden and Pope I demonstrate how (i) Johnson focuses in Nature an experience of life which is distinguished from the commonplace but which is also deeper than psychology; and (ii) that Nature is rooted in a religious experience associated but not absolutely equated with Christianity and which provides Johnson with a conception of memory to mitigate his sceptical sense of the discrepancy between the intentions and achievements of a writer. With reference to the Lives of Milton, Butler, Rochester and Parnell, I discuss how the structures of the Lives work to trace the way a poet realises his own genius, and how Johnson's thought operates redemptively to establish a memory for the poet who does not. Two large, related chapters apply this knowledge of Johnson's literary biography in detailed analysis of his encounter with the lives and works of Dryden and Pope. Modern and contemporary criticism is compared to Johnson's understanding of Dryden's translations -- in which, I argue, Johnson finds Dryden's genius most fully realised -- and of Pope's Rape of the Lock and Iliad Book I, and what they reveal of Pope's mind and his relation to his art. These Lives indicate (i) that the continuity of past with present embodied so attractively in Dryden's translations is informed by his Catholicism and reveals Nature; and (ii) that Pope's sacrifice of Nature maintained the integrity of his personal character-and offered the age a refinement it sought -- but also revealed a split between art and Nature -- not characteristic of Dryden -- which made civilized writing problematic. In conclusion I briefly draw out Johnson's general historical position represented by his comparison of Dryden with Pope, as he looked back on the Lives of the Poets and on the previous century.

Full textAbstract:
La présente thèse essaie d'apporter une contribution à l'étude du classicisme de Dryden en explorant l'oeuvre de divers auteurs de l'Antiquité (Aristophane, Lucien, Silius Italicus) que la critique n'avait pas mis en relation avec la poésie drydienne aussi bien qu'en approfondissant l'examen d'influences qui avaient déjà été prises en compte (Pindare, Juvenal) pour en renouveler l'approche. Le rapport à la parole, au pouvoir du "logos" qu'exprime l'Auteur à travers ses personnages, en accord avec les modèles anciens, est les fil conducteur des analyses de la première partie de la thèse, où l'étude du rôle de l'exemple de Silius dans "Annus Mirabilis" ouvre la voie à l'exploration de l'univers satirique drydenien, comme celles de la deuxième partie, qui ont pour objectif d'attribuer a "To the Pious Memory of Mrs Anne Killigrew" et à "Alexander's Feast" le statut d'épinicies, d'odes victoriales. La troisième partie est une étude de la présence de Juvénal dans la poésie de l'auteurThe present thesis seecks to contribute to the study of Dryden's classicism, both by exploring the works of various authors of antiquity (Aristophenes, Lucian, Silius Italicus) unrelated to Dryden's poetry by the critics, and by making a more detailed examination of the already recognised influences (Pindare, Juvenal) while adopting a novel approach to these. The emphasis placed ont he relationship to the word, the power of the "logos" as expresses by the author through his characters in accordance with the ancient models, closely links the analysis contained in part one of the thesis, where a study of the influence of Silius on "Annus Mirabilis" paves the way for an exploration of Dryden's satiric world, with those of part two, which aims to characterize the poems "To the Pious Memory of Mrs Anne Killigrew" and "Alexander's Feast" as victory odes. The final part three is a study of Juvenal's presence in Dryden's poetry

Full textAbstract:
The dryad Minois dryas, described in 1763 by Giovanni Antonio Scopoli, belogs to our endangered species of butterflies. Its expansion today is restricted to a few localities in Central and Southern Bohemia and Southern Moravia only. Renewal and preservation of appropriate types of biotopes and research of its autecology and bionomy play the key roles in conservation of this species. The intention of my thesis was to identify host plants of Minois dryas caterpillars, to find out which grass is the most preferred one and to verify the correctness of hypothesis that the most preferred plant is also dominant from the range of potential host plants in the chosen area (a meadow in the vicinity of Žehuň in Central Bohemia). In the first part of experiment caterpillars were offered grasses collected in Žehuň. Plants which were eaten by caterpillars, were determined as host plants. According to results of this stage the host plants of caterpillars in the Czech republic are Dactylis glomerata, Bromus erectus, Festuca rubra, Arrhenatherum elatius and Carex acutiformis. In the second part of experiment caterpillars were offered all grasses evaluated in the first part as host plants and frequency of eaten / untouched leaves was recorded. Results identified Bromus erectus as the most desired grass and statistical proved there was a strong dependance among the plants . As Bromus erectus is indeed the most dominant grass in the location (approx. 30 % of all grasses), the hypothesis was confirmed. The experiment contributed with some other knowledge about dryad's bionomy. Observations confirmed that caterpillars pupate at the turn of June and July, primarilly at night. Larvae pupates in or on the ground. I did not notice any silk spinning during the time of pupation which is mentioned by Beneš et al. (2002). The pupal stage lasted 22 -- 23 days. Butterflies hatched in the morning. Imagos chose red watermelon as a food in most cases which proves that adults prefer red colour while deciding on their food (Vrabec et al., 2007).

Widmer, Matthias. "Virgil after Dryden : eighteenth-century English translations of the Aeneid." Thesis, University of Glasgow, 2017. http://theses.gla.ac.uk/8109/.
Full textAbstract:
John Dryden’s 1697 translation of Virgil’s Aeneid is often seen as the pinnacle of an English tradition that read the Roman poet in primarily political terms and sought to relate his epic to contemporary matters of state. The present thesis takes a different approach by examining Dryden’s influence on his eighteenth-century successors to determine, on the one hand, what they hoped to accomplish by retranslating the same original and, on the other hand, why none of them was able to match his success. Dryden’s impact as a stylistic (rather than an ideological) model was balanced not only against a newly emphasised ideal of literalism but also against a whole range of other creative forces that posed at least an implicit challenge to his cultural dominance. Chapter 1 demonstrates Dryden’s systematic refinement of the couplet form he inherited from his predecessors and draws on his theoretical writings to suggest how it can be seen as a key aspect of his particular approach to Virgil. Chapter 2 discusses Joseph Trapp’s blank verse Aeneid and its debt to Dryden’s couplet version; I will show that the translator’s borrowings from the precursor text run directly counter to his declared ambitions to remain faithful to Virgil. Chapter 3 focusses on Christopher Pitt, the Virgil translator who came closest to paralleling Dryden’s popular acclaim; encouraged by fellow men of letters, Pitt published his translation in gradually revised instalments that reflect Dryden’s growing influence over time. Alexander Strahan, the subject of Chapter 4, aligned himself with a parallel tradition of Miltonic renderings by absorbing numerous expressions from Paradise Lost into his blank verse translation of the Aeneid and frequently used them to foreground thematic connections between the two epics; however, his revisions, too, show him moving closer to Dryden as time went by. James Beresford, discussed in Chapter 5, stands out among the other Miltonic translators by virtue of giving his borrowings in quotation marks – a practice that will be illuminated in connection with the multidisciplinary work of the artist Henry Fuseli and the equally Mil-tonic Homer translation that William Cowper composed under the latter’s supervision. Chapter 6, finally, offers an analysis of William Wordsworth’s failed attempt at translating the Aeneid. Given that he was one of the key reformers of English poetry, Wordsworth’s return to the traditional couplet form at a later stage in his career is surprising, as is the fact that his style became more Drydenian the further he proceeded.

International Telemetering Conference Proceedings / October 26-29, 1998 / Town & Country Resort Hotel and Convention Center, San Diego, CaliforniaDryden real-time flight simulators encompass the simulation of pulse code modulation (PCM) telemetry signals. This paper presents a new method whereby the calibration polynomial (from first to sixth order), representing the conversion from counts to engineering units (EU), is numerically inverted in real time. The result is less than onecount error for valid EU inputs. The Newton-Raphson method is used to numerically invert the polynomial. A reverse linear interpolation between the EU limits is used to obtain an initial value for the desired telemetry count. The method presented here is not new. What is new is how classical numerical techniques are optimized to take advantage of modern computer power to perform the desired calculations in real time. This technique makes the method simple to understand and implement. There are no interpolation tables to store in memory as in traditional methods. The NASA F-15 simulation converts and transmits over 1000 parameters at 80 times/sec. This paper presents algorithm development, FORTRAN code, and performance results.

Full textAbstract:
This dissertation is divided into three parts. The first part, 'Copious Dryden', considers the various inter-connected factors which inform the noticeably expansive status of Dryden's translations of Virgil. It argues that the underlying principle behind these factors is Dryden's desire to demonstrate how his own approach to Virgil has been shaped by various key poets who acted as intermediaries for the original texts. These poets stretch across a broad chronological range, from Virgil's near-contemporaries (Horace, Ovid) to Dryden's (Denham, Cowley, Milton) and a range of figures in between (Lucan, Statius, Spenser), including Dryden's own younger self. It subsequently identifies three distinct strands of Virgil's reception - the Prosodic, Laureate, and Lacrimose Virgil - before discussing their origins and their influence on Dryden's Virgil. The second part, 'Footfalls', discusses how Dryden's first translations from the Aeneid in the 1680s are noticeably self-reflexive: they use a number of characters from the poem to explore the nature of his own inheritance from Virgil, both as a poet and as a translator, a relationship which incorporates erotic, fraternal and filial aspects. The third part, 'Original Copies', explores how Dryden concentrated on a number of father-son pairings in Virgil as a means of meditating on questions of political and poetical succession, and the frequent points of contact between these spheres. It argues this ultimately allowed Dryden not only to proclaim his political loyalties to the displaced Jacobite branch of the House of Stuart, but also to allot himself a central, if fluid, role within a poetical dynasty, thanks to his conviction that poetical tradition is bestowed as well as inherited. This dissertation concludes with a brief consideration of Dryden's own poetic successors, Congreve and Pope, and the manner in which they claimed their place within this poetic dynasty.

O presente trabalho visou o acréscimo de informações sobre a ecologia da polinização de P. alata Dryander, para a região de Florianópolis, SC. Enfatizou-se o estudo da fenologia, da biologia floral, das características dos frutos e dos polinizadores. Foi também avaliada a ocorrência de sobreposição de polinizadores entre esta espécie e Passiflora edulis f. flavicarpa Deg. O florescimento de P. alata ocorreu em 3 períodos do ano. A morfologia e fisiologia floral enquadram P. alata na síndrome de melitofilia, com o sistema reprodutivo caracterizado como auto-incompatível. Observou-se um polimorfismo dos frutos para várias características. Abelhas de grande porte foram consideradas os principais polinizadores. O principal recurso forrageado pelas abelhas foi o néctar, o qual foi secretado abundantemente ao longo do dia. Os visitantes florais de P. edulis f. flavicarpa Deg. foram compartilhados com P. alata, sugerindo a ocorrência de competição por polinizadores entre estas duas espécies de maracujás, quando ocorrer sobreposição do período de florescimento. Os resultados demonstraram um grande potencial para produção de P. alata na área avaliada.

Full textAbstract:
The Younger Dryas Impact Hypothesis (YDIH) states that North America was devastated by some sort of extraterrestrial event similar to 12,800 calendar years before present. Two fundamental questions persist in the debate over the YDIH: Can the results of analyses for purported impact indicators be reproduced? And are the indicators unique to the lower YD boundary (YDB), i.e., similar to 12.8k cal yrs BP? A test reported here presents the results of analyses that address these questions. Two different labs analyzed identical splits of samples collected at, above, and below the similar to 12.8ka zone at the Lubbock Lake archaeological site (LL) in northwest Texas. Both labs reported similar variation in levels of magnetic micrograins (>300 mg/kg >12.8ka and <11.5ka, but <150 mg/kg 12.8ka to 11.5ka). Analysis for magnetic microspheres in one split, reported elsewhere, produced very low to nonexistent levels throughout the section. In the other split, reported here, the levels of magnetic microspherules and nanodiamonds are low or nonexistent at, below, and above the YDB with the notable exception of a sample <11,500 cal years old. In that sample the claimed impact proxies were recovered at abundances two to four orders of magnitude above that from the other samples. Reproducibility of at least some analyses are problematic. In particular, no standard criteria exist for identification of magnetic spheres. Moreover, the purported impact proxies are not unique to the YDB.

Full textAbstract:
This thesis handles a number of passages in the poems of Dryden and Pope which show that both poets had been deeply impressed by Paradise Lost. These passages are so various and numerous (this is one of the principal claims to novelty of this thesis) that it is no longer possible to maintain that Milton was in different ways an isolated figure. Secondly, the effect on both poets of these passages they admired in Paradise Lost is such as to justify the claim that in important respects Milton made Dryden and Pope. The principal point of this thesis is to provide evidence suggesting that the implied verdict on Paradise Lost which emerges from Dryden's and Pope's manifold uses of the poem in producing their own poetry, is radically unlike any of the verdicts pronounced on Paradise Lost by the most gifted readers of poetry during the years from Wordsworth's death down to the present. In Dryden and Pope there was a common underlying estimate of the permanent worth of Paradise Lost. This finding entails an examination of the nature and development of the divergent tradition, which is traced back to a point in the middle years of the nineteenth century, and has been maintained without substantial addition or modification until recent times. However, the bulk of the thesis is not polemical. God, Man and Nature are the topics which principally stirred the two poets in their reading of Paradise Lost. Nevertheless, neither Dryden nor Pope separated their feelings for Milton's Nature from their feelings for Milton's Man and Milton's God. The nature found by Dryden and Pope was a nature crowned by human nature, but was invisible until they were confronted by the intermingling and interpenetration of the human and the divine. Common to Dryden and Pope was the conviction that Paradise Lost was a unique creation and unique above all because these three elements were so interrelated, and one could never be isolated without involving all the others. The whole question of what constitutes evidence of Dryden's and Pope's contact with Paradise Lost is examined in a separate appendix. Further appendices include lists of all the instances known to me.

Full textAbstract:
Dryas iulia alcionea é uma espécie de borboleta que apresenta dimorfismo sexual em relação à coloração e ao tamanho das asas. Estudos em populações naturais mostraram que a variação no tamanho das asas dos machos é inferior a das fêmeas, sugerindo a ação de forças seletivas sobre a variabilidade das asas dos machos. Nesta tese, são apresentadas e discutidas evidências comportamentais, de desenvolvimento, genéticas e populacionais que podem explicar parcialmente os padrões morfológicos observados. Os principais resultados da tese são: (1) a forma das asas dos machos parece ser adaptada para vôos de longa duração, com alta eficiência energética, enquanto a forma das asas das fêmeas seria adaptada para vôos curtos, com alta manobrabilidade; (2) o repertório comportamental dos machos é maior do que o das fêmeas e diretamente relacionado à tentativa de efetuar cópula; (3) os machos buscam e cortejam ativamente as fêmeas (estratégia de patrulhamento); (4) as fêmeas parecem ter um papel decisivo no sucesso copulatório dos machos, já que a intensidade do cortejo dos machos parece não influenciar o sucesso copulatório; (5) os machos com padrões comportamentais menos variáveis parecem ter maior sucesso copulatório; (6) machos grandes e pequenos se comportam da mesma maneira frente a fêmeas receptivas, sugerindo que não existam estratégias alternativas para compensar efeitos causados por tamanhos corporais diminutos; (7) o tamanho dos machos não parece influenciar a escolha das fêmeas; (8) não há disputa direta entre machos (comportamento agonístico); (9) o tamanho das asas é uma característica com um moderado fator genético; (10) a correlação genética entre as características das asas dos machos e fêmeas é imperfeita, o que permitiria ou indicaria a ação de seleção sobre o dimorfismo sexual de tamanho das asas; (11) a correlação entre características das asas anteriores e posteriores é baixa, sugerindo uma considerável independência genética entre as características dos dois conjuntos de asas; (12) o tamanho apresenta significativa variação entre populações e estações do ano, sendo fortemente influenciado pelos recursos alimentares e temperatura durante o desenvolvimento larval. Com essas evidências, o modelo do equilíbrio diferencial de evolução poderia ser utilizado para explicar o dimorfismo sexual de tamanho observado, já que afeta as histórias de vidas, ecologia e comportamento. Assim, o dimorfismo sexual em D. i alcionea seria um epifenômeno resultante de forças seletivas atuado diferentemente sobre machos e fêmeas.Dryas iulia alcionea is a butterfly species that shows sexual dimorphism in relation to wing color and size. Studies of natural populations showed that the variation in wing size in males is lower than in females, suggesting the action of selective forces on wing size variation in males. In this thesis, I present and discuss behavioral, developmental, genetic and populational evidences that could explain the morphological patterns observed. The main results of the thesis are: (1) wing shape in males seems to be adapted for long lasting flights, with high energetic efficiency, while wing shape of females seems to be adapted for short flights, with improved maneuverability; (2) males have a more numerous mating behavior repertoire than females, which seems to be directly related to attempts of genital coupling; (3) males court and actively seek for mates (patrooling strategy); (4) females seem to have a decisive role in the copulatory success of males, since the intensity of male courtship does not seem to influence male copulatory success; (5) males with less variable behavioral patterns during courtship seem to have greater copulatory success; (6) large and small males court receptive females in the same way, suggesting that they do not use alternative strategies to compensate for effects caused by small body sizes; (7) the male size does not seem to influence female choice during courtship, (8) there is no direct competition between males, with agonistic behavior; (9) wing size has a moderate genetic basis; (10) genetic correlation between males and females, for some wing traits, seems to be imperfect, which could indicate or allow the action of sexual selection on wing size and shape; (11) the genetic correlation between forewings and hindwings is low, suggesting some genetic independence between the two sets of wings; (12) wing size has significant variation among populations and seasons and is strongly influenced by diet and temperature during development. Considering these evidences, the differential equilibrium model of evolution could be used to explain the sexual size dimorphism observed, since it affects life histories, ecology and behavior. Thus, the sexual size dimorphism in Dryas iulia alcionea could be an epiphenomenon resulting from selective forces acting differently on males and females.

Full textAbstract:
Francisco de Enzinas (c. 1520-1552), a translator of biblical and classical texts into Spanish, is one of the lesser-known of that group of sixteenth-century heterodox Spaniards whom scholars such as Eduard Boehmer and A. G. Kinder have classified as Protestants or Reformers This categorization is largely based upon Enzinas's connection with major German and English Reformers which began, with one exception, in or after 1546.T he present thesis investigates the earlier period of Enzinas's career, before the Council of Trent in 1546 constituted the Vulgate the authentic canon for the faithful, signalling ecclesiastical retreat from humanist biblical principles. The author argues that Enzinas can best be understood not as an adherent of any Protestant confession but as an evangelical humanist who sought the essence of Christianity in the biblical evangel and who shrank from scholastic argumentation in its Protestant as well as Roman Catholic guises. Enzinas showed evidence throughout his life of this stance developed during the period studied by this thesis. The author further argues that Enzinas should be seen primarily as a Spanish publisher of texts rather than as a Reformer, and that his vocatio to this humanist task provides the best explanation of his life's choices. The present thesi sexplores the historical and religious contexts, printing history, language, and ideas of Enzinas's three major publications of this period: Breve y compendiosa institugion de la religion Christiana (1541), the Nuevo testamento( 1543), and De statu BeIgico et refigione Hispanica (written in 1545). The study of the Instilugion sheds light on Enzinas's humanistic approach to theology, and uses unpublished documentation to show how an attempt to disseminate this work in Spain prejudiced all of Enzinas's later literary efforts. The study of Enzinas's Nuevot estamento explores the means which the translator used to try to win authorization for this Spanish Scripture, and this thesis argues that he proceeded with full consciousness of the imperial laws controlling printing. De statu BeIgico, Enzinas's only wholly original work, is used here in part as a sourcef or understanding what Enzinas believed to be the essence of evangelical religion. The thesis includes a two-part biography of Enzinas which incorporates previously unstudied material such as the evidence for his connection with Oxford during his formative years. A descriptive bibliography of his works is appended.

Full textAbstract:
This thesis traces the development of Arthurian literature through the sixteenth and seventeenth centuries. A comparison of the Medieval flawed romance king and of the epic warrior of the English histories with Spenser's treatment of Arthur in The Faerie Queene reveals the extent of Spenser's originality. Spenser irreversibly altered the course of English Arthurian literature by rejecting Arthur's traditional human failings and by creating a figure of moral and political idealism. These forms of perfection - intimately connected in the poem to Protestantism, Neoplatonism, nationalism and monarchism - initiated two divergent, but not mutually exclusive, strands of Arthurian literature in the seventeenth century. Spenser's Arthurian idealism manifests itself in the courtly masques, and especially in Ben Jonson's Prince Henry's Barriers (1610) and Prince Oberon (1611), Thomas Carew's Coelum Britannicum (1633) and William Davenant's Britannia Triumphans (1637). The masques affirm the link between Spenserian Arthurianism and moral perfection, but the Spenserian poets soon raised doubts regarding this pure 'idealism'. This group of poets, particularly Drayton, simultaneously imitate and alter Spenser's use of Arthurian material. In Poly-Olbion (1633)Drayton adapts Spenser's concept of Arthur in order to contrast Arthurianism with Christianity and historicity. Spenser's Arthurian concepts of heroism, nationalism and monarchy initiated in The Faerie Queene are prominent in the political panegyrics of the Stuart period, and are fully explored by Ralph Knevett in A Supplement of the Faery Queene (1635). While Knevett proposes an allegorical representation of political idealism in his Arthurian material, he simultaneously evinces an astute awareness of the increasing contemporary demands for greater veracity and realism in fiction. Towards the end of the seventeenth century Arthurian idealism was losing its momentum. Its final demise can be traced in the works of Milton and Dryden. Milton was initially attracted by Spenser's treatment of Arthur, but he followed the Spenserians in utilizing the moral Arthurian material primarily to foreground the higher truths of Christianity in Paradise Lost (1667) and Paradise Regained (1671). By the time Dryden completed King Arthur (1691), the Arthurian tradition could no longer sustain its traditional imaginative appeal.

O presente estudo investigou as atividades antioxidantes in vitro, ex vivo e in vivo dos extratos de folhas Passiflora alata e Passiflora edulis, plantas usadas na medicina popular e ricas em polifenóis, compostos com reconhecida atividade antioxidante. No modelo experimental in vitro, ambos os extratos demonstraram atividade antioxidante e proteção contra dano protéico induzido por glicose. Fatias de fígado de ratos foram utilizadas como modelo ex vivo. Tanto o extrato de P. alata quanto o extrato de P. edulis protegeram de forma significativa o dano protéico e a morte celular induzidos por FeSO4. Como a P. alata é uma droga oficial da Farmacopéia Brasileira, os efeitos antioxidantes deste extrato foram investigados in vivo. Ratos machos Wistar receberam tratamento intragástrico de extrato de folhas de P. alata (1 e 5 mg/kg), trolox (0,18 mg/kg) ou água (controle) durante 30 dias, seguido de uma dose de CCl4 (3 ml/kg, i.p.) no 30º dia. O dano hepático e os efeitos antioxidantes do pré-tratamento com extrato de P. alata foram avaliados em vários órgãos. Quando comparados ao grupo controle, os ratos pré-tratados com o extrato demonstraram dano hepático menor, evidenciado por um grau menor de necrose, níveis menores de lipoperoxidação e maior atividade das enzimas superóxido dismutase e catalase. Adicionalmente, níveis menores de lipoperoxidação cardíaca foram observados com o pré-tratamento de P. alata (5mg/kg). Os resultados obtidos neste estudo indicam que os extratos de Passiflora são fontes potenciais de antioxidantes naturais. Estudos adicionais investigando o papel de compostos isolados destes extratos em patologias humanas onde o estresse oxidativo está envolvido são necessários.

Full textAbstract:
This thesis addresses the consequences of the last glaciation on the distribution and genetic diversity of arctic flora. The principal aim is to infer the full-glacial and postglacial migrational history of Dryas integrifolia M. Vahl. (Rosaceae) from the intraspecific phylogeny of cpDNA haplotypes along with pollen and macrofossil distribution data. The results suggest that four refugia existed during the last glaciation and that each served as significant sources of recolonization when the ice retreated. The two most important refugia are located in the northwestern Arctic (Beringia and the High Arctic), with two other refugia located southeast of the ice sheet and along the coastal regions of the eastern Arctic. High genetic substructure among populations is likely attributable to past vicariance and recent recolonization events, whereas high local diversity is probably indicative of recolonization from several sources and high gene flow in recent time.

Full textAbstract:
This thesis uses geological field data and numerical ice sheet modelling to study the Younger Dryas ice cap in Scotland. The Younger Dryas stadial is important because it represents the most recent period of high-magnitude global climate change, and was marked by the expansion of ice sheets in North America and Scandinavia, and the regrowth of glaciers in the British Isles. An integrated methodology linking field results and modelling is developed and applied here, specifically focussing on the deposits, landforms, and palaeoglaciology of Younger Dryas glaciers in western Scotland. This combined approach enables data of different scales to be compared, and connected, from local sedimentological investigations and empirically derived reconstructions, to regional ice-sheet simulations from a high-resolution numerical model. Previous geological mapping in western Scotland resulted in contradictory views of the thickness and extent of ice during the Younger Dryas, consequently leading to uncertainty about the dynamics of the former ice cap. By using a ‘landsystem’ method to characterise the terrain, it is argued here that geological evidence in the study area implies a relatively thick central ice cap that fed steep outlet glaciers around its margins. These glaciers oscillated throughout the stadial, and during deglaciation produced suites of moraines that marked successive positions of glacier retreat. Widespread preservation of superimposed landforms, and of sediment sequences pre-dating the Younger Dryas, suggest that, despite being active, the Younger Dryas ice cap was not particularly erosive in its central area and only subtly modified its bed. These geological interpretations are supported by high-resolution numerical modelling of the ice cap, which reveals clear spatial variability in the velocity structure, thermal regime, and flow mechanism of the ice cap; patterns that led to local contrasts in basal processes and diversity in the geological imprint. These model experiments also highlight the non-linear relationship between climate forcing and glacier response, identifying evidence of ice sheet hysteresis and climatically decoupled glacier oscillations – concepts as relevant to geological investigations of former ice masses as they are to the prediction of glacier response under future climate changes.

Full textAbstract:
The Loch Lomond Stadial (LLS) refers to the abrupt return to severe cold conditions that occurred in Britain, between 12.9 and 11.7 ka, subsequent to the retreat of the last (Late Devensian) British-Irish Ice Sheet. This period has long been associated with the regrowth of glaciers in upland areas of Britain and left a wealth of geomorphological evidence in the landform record. However, previous research on these glaciers has largely comprised localised case studies, producing a fragmented and spatially inconsistent dataset. This thesis draws together the published geomorphological evidence for Loch Lomond Stadial glaciation to build a coherent picture of the extent, style and dynamics of glaciation during the stadial. Geomorphological mapping of glacial landforms associated with this period is compiled from the published literature to create a map and geographic information systems database of over 95,000 features. The evidence used to produce this map is critically assessed in the most comprehensive review of the Loch Lomond Stadial to date and is used to identify conceptual themes, common to the geomorphology in multiple sub-regions within Scotland, England and Wales. Persisting uncertainties, particularly regarding the extent and timing of Loch Lomond Stadial glaciation, are discussed and recommendations of future research to address these are made. Building on this review, the glacial geomorphological map is then used to construct five glacial landsystem models which reflect the style of Loch Lomond Stadial glaciation; the cirque/niche glacier landsystem, the alpine icefield landsystem, the lowland piedmont lobe landsystem, the plateau icefield landsystem and the ice cap landsystem. Use of these models to classify the Loch Lomond Stadial glacial geomorphology reveals the spatial distribution of each landsystem. Three styles of glacier retreat are represented by the glacial geomorphology. It is demonstrated that both landsystem and retreat style reflect the combined importance of pre-existing topography and palaeoclimate. Given the paucity of dating constraints on Loch Lomond Stadial landforms, the thesis pilots the use of a relative dating technique using soil chronosequences to differentiate between Loch Lomond Stadial and older moraines in the English Lake District. The results of this study highlight the potential of this technique to discriminate between Loch Lomond Stadial and pre-Loch Lomond Stadial moraines in Britain, although further work is required.

Full textAbstract:
This study discusses the extent to which hunter-gatherer mobility strategies are changed by abrupt climate change events by monitoring changes in lithic assemblage compositions through the Pleistocene/Holocene Transition, from ca. 14,000 cal BP to 10,000 cal BP in northwest Europe, with a focus on the Younger Dryas Stadial event, which occurred around 12,900 cal BP to 11,700 cal BP. A set of predicted archaeological indicators were formed from existing theoretical models, based largely on Binford’s logistical and residential mobility model, with the expectation that a more residential mobility strategy would be used by hunter-gatherer-populations during warmer climatic phases (i.e. the Allerød and Preboreal) and a more logistical mobility strategy would be used during cold climatic phases (i.e. the Younger Dryas). The lithic assemblages from sites across northwest Europe were then compared with these expectations in order to determine if a shift from a more residential strategy to a more logistical strategy can be seen from the lithic record. Additionally, a further comparative dataset was collected from south Europe in order to determine if there were differences in the response to the Younger Dryas at lower latitudes where the impact of this event is assumed to be less severe. The results found that in northwest Europe there is evidence to suggest there was indeed a shift from a more residential strategy during the warm Allerød interstadial to a more logistical strategy during the Younger Dryas Stadial, and the adoption of a more residential strategy with the return of warmer conditions during the Preboreal. However, it appears that the Preboreal Interstadial shows significant differences between the Allerød Interstadial, with the Preboreal sharing more characteristics in common with the Younger Dryas. This has been interpreted as a response to the unstable climatic conditions reported from the environmental evidence in this region during the Preboreal, which may have limited the ability of hunter-gatherer populations to return to similar levels of residential mobility seen during the Allerød. The south Europe dataset provides evidence that the lesser impact of the Younger Dryas at lower latitudes brought about a more muted response by hunter-gatherer populations to this event when compared with the northwest. However, there appears to be a reversal of that seen in the northwest, with more logistically mobile populations during the Allerød and especially the Preboreal, and more residentially mobile populations during the Younger Dryas. This is despite the environmental evidence showing a very similar environmental response to the northwest, with a distinct opening of the landscape during the Younger Dryas. The apparent difference in mobility strategies appear to be more related to the available faunal species within a region and their behaviour within their environment rather than directly to the climate. In the south, species such as red deer and ibex are the main source of faunal subsistence throughout the Pleistocene/Holocene Transition, unchanged by shifts in temperature and environment, but the way in which hunter-gatherers would hunt such species would be expected to change in more wooded environments compared with more open environments. If we compare this with the northwest, there is evidence of a distinct change from hunted prey, such as red deer, during the Allerød and Preboreal, to reindeer and horse during the Younger Dryas (although faunal preservation is poor in this region). With this shift to a more mobile prey species, along with a harsher, more open environment it may be more suitable to practise a more logistical strategy. Additionally, the instability of the Preboreal may have also changed the environment on a smaller scale, which would have required the hunting of warmer climate prey in shifting local environments, much like that of the Younger Dryas in south Europe. This might explain the differences seen between the Allerød and the Preboreal. Overall, there appears to be strong evidence supporting the theory that colder, harsher climates promote a more logistically mobile response from hunter-gatherer populations as seen in the northwest of Europe, and that there was a more muted, different response to the Younger Dryas in the lower latitudes of south Europe. However, it is the opinion here that changes in human mobility are not controlled directly be climatic conditions, rather controlled by the available major prey species and their behaviour in changing environments.

Full textAbstract:
One of the prominent features in sediment sequences formed around the AllerOd-Younger Dryas transition (c. 12.9-12.8 ka bp) in North America is a dark layer of organic-rich material, i.e. the black mat. The black mat sequences in southeast Arizona contain a thin sandy basal layer corresponding to the lower Younger Dryas boundary. Trace element concentrations in the lower Younger Dryas boundary sediments, in the black mat, in the host sediments, and in charcoal from Western Europe and southeast Arizona were studied using LA-ICP-MS. The black mat samples and samples of the underlying host sediments display compositions similar to the average continental crust, while the sediments from the lower Younger Dryas boundary are enriched in rare earth elements, Ni, and Co whereas Ta, Nb, Zr, and Hf are depleted relative to the rare earth elements. Such a difference in compositions between the lower Younger Dryas boundary sediments and other sediments points to a short enigmatic event, which changed conditions of sedimentation just before the onset of the Younger Dryas cooling. The presence of products of biomass burning of still unknown origin is suggested on the basis of trace element features of sediments from the lower Younger Dryas boundary.

Full textAbstract:
Sveriges geomorfologi har till största del bildats under den senaste glaciationens erosion och depositions processer. Vid denna glaciations avsmältning rann smältvattnet bort från glaciären i isälvarna genom tunnlar under inlandsisen. Från dessa isälvar bildas åsar när materialet som transporterats med glaciären förs med i det turbulenta flödet i isälven innan det avsätts och bygger upp dessa långsträckta terrängformer. Isälvarnas position under inlandsisen bestäms av hydrauliska potentialen vilken bestämmer rörelseriktningen för vatten under glaciären. I vissa områden kommer den ha en lägre potential och andra en högre potential beroende på isens tjocklek och formen av den underliggande terrängen. Där den hydrauliska potentialen konvergerar kommer isälvar bildas av de stora mängder smältvatten som transporteras bort. Syftet med detta projekt var att bekräfta åsbildningen i Svealand genom att göra en modellering av den hydrauliska potentialen under inlandsisen i ArcGIS. Två modelleringsalgoritmer för flödesriktning kallade D8 och D-infinity, jämfördes också för att avföra vilken av dessa som bäst modellerar smältvattnets flödesvägar under inlandsisen. Tidsintervallen 11 000, 12 000 och 13 000 år sedan valdes för denna undersökning då inlandsisen då gick från att ligga strax söder om Svealand till mellersta Svealand. Mellan 11 000 och 10 000 år sedan avsmälte glaciären väldigt hastigt och retirerade till Kaledoniderna i norra Sverige och används därför ej i denna undersökning. I ArcGIS beräknades hydropotentialen för de olika tidpunkterna varefter sänkor i rastret fylldes upp. Flödesriktningen och flödesackumulationen beräknades för både D8 och D-infinity. Från flödesackumulationen togs isälvarna fram genom en omklassning av rastret. För att avgöra vilken flödesriktningsalgoritm som modellerade smältvattnets flödesvägar under inlandsisen bäst användes ett verktyg som summerade antalet pixlar av isälvar som låg under polygoner över nutida åsar i Svealand. Från detta beräknades en procentskillnad mellan D8 och D-infinity för att avgöra vilken av dem som stämde bäst överens med de nutida åsarna. En karta för varje tidsintervall som undersöktes samanställdes med de modellerade isälvarna och de nutida åsarna i Svealand för att visuellt avgöra om det gick urskilja en kronologisk bildningsföljd av åsarna. D-infinity beräknades modellera isälvarna upp till 2,5 procentenheter bättre än D8. Skillnaden mellan modelleringsalgoritmerna minskade i takt med att glaciärtäckningen av Svealand minskade. I kartorna som sammanställdes gick en viss kronologisk trend att se. Vissa åsar som när de låg långt från inlandsisens kant blev inte modellerade som isälvar förrän inlandsisens kant kom närmare dem. Vissa modellerade isälvar låg inte direkt på de nutida åsarna utan lite till sidan av dem vilket skulle kunna bero på att den rumsliga upplösningen som modelleringen gjordes i var för grov eller att fler faktorer behöver tas med i modelleringen. Till exempel skulle snävare tidsintervall kunnat användas i modelleringen för att bekräfta den kronologiska bildningsföljden av åsar. Transmissivitetens koppling till den hydrauliska potentialen och avståndet mellan isälvar hade möjligtvis också förbättrat modelleringen av isälvarnas rumsliga position.Sweden's geomorphology has largely been formed during the recent glaciation erosion deposition processes of recent glaciation. During the deglaciation, the meltwater ran away from the glacier in the channel ice streams through tunnels under the ice sheet from which eskers were formed. The position of the glaciers in the ice sheet is determined by the hydraulic potential, which determines the direction of movement of water below the glacier. In some areas, it will have a lower potential and others a higher potential depending on the thickness of the ice and the shape of the underlying terrain. In places where the hydraulic potential converges, ice rivers will be formed by the large amounts of melt water transported away. The purpose of this project was to confirm the esker formation in Svealand by modelling the hydraulic potential during the glaciation in ArcGIS. Two flow direction modelling algorithms, D8 and D-infinity, were also compared to determine which of these best models the meltwater flow paths under the ice sheet. The years 11,000, 12,000 and 13,000 years ago were chosen for this study as the ice sheet then went from lying just south of Svealand to central Svealand. Between 11,000 and 10,000 years ago, the glacier melted very rapidly and retreated to the Caledonids in northern Sweden and is therefore not used in this study. In ArcGIS, the hydraulic potential for the different time intervals was calculated, after which sinks in the grid were filled up, the flow direction and the flow accumulation were calculated for both D8 and D-infinity. From the flow accumulation, the channel ice streams were generated by a reclassification of the grid. To determine which flow direction algorithm best modelled the meltwater flow paths under the ice sheet, a tool was used that summed the number of pixels of channel ice stream that were below polygons over current eskers in Svealand. From this, a percentage between D8 and D-infinity was calculated to determine which of them best matched the current eskers. A map for each assessed year was compiled with the modelled channel ice streams, ice sheet edge and the current eskers in Svealand to visually determine whether a chronological sequence of the eskers could be discerned. D-infinity was estimated to model the channel ice streams up to 2.5 percentage points better than D8. The difference between the modelling algorithms decreased as the glacier coverage of Svealand decreased. In the maps that were compiled, a chronological trend could be inferred to a certain point. Some eskers that, when they were far from the edge of the ice sheet, were not modelled as channel ice streams until the edge of the ice sheet were much closer to them. The modelling could be improved by increasing the resolution in which the modelling was made as it might have been too coarse or that more factors need to be included in the modelling. For example, narrower time intervals could be used in the modelling to confirm the chronological sequence of ridges. The connection between the transmissivity and the hydraulic potential and the distance between ice rivers may have also improved the modelling of the spatial position of the ice rivers.

Plusieurs questions se posent lors des études paléo-environnementales en Asie du sud-ouest : (i) le retard de 4 500 ans de l’expansion postglaciaire de la forêt dans le Zagros, (ii) les changements hydroclimatiques au début de la néolithisation et de la domestication et (iii) le rôle des changements climatiques dans les changements écosystémiques et sociétaux. En raison de la position géographique stratégique de l’Iran, les études paléo environnementales en Iran peuvent aider à répondre à ces questions. Selon nos résultats, les chironomes (insectes - diptères), utilisés comme bioindicateurs paléohydrologiques, constituent un outil prometteur pour étudier les impacts du climat et des activités humaines sur les écosystèmes. L’outil chironome permet de révéler efficacement des interventions anthropiques passées dans la gestion de l'eau. La comparaison avec d’autres indicateurs paléoécologiques a confirmé l’utilité des chironomes fossiles pour les reconstructions paléohydrologiquesSeveral questions are still to be addressed in the palaeoenvironmental studies of SW Asia including: (i) the 4500 yr long delay in post-glacial expansion of the deciduous forest of Zagros, (ii) the hydroclimatic changes during the early neolithization and domestication, and (iii) the role of climate versus anthropogenic forcings in ecosystem and societal changes. Palaeoenvironmental studies in Iran can help to address the above questions because of the strategic geographical position of this country in SW Asia. According to our results, chironomids (insects - diptera), as paleohydrological bioindicators, are a promising tool to investigate climate and human impacts on ecosystems. They have proved to be very good proxies of hydrological conditions of wetlands and also to reveal anthropogenic water management interventions in the past. The comparison with other palaeoecological indicators confirmed suitability of subfossil chironomids for palaeohydrological reconstructions

Full textAbstract:
The presence of the sea ice diatom biomarker IP25 in Arctic marine sediments has been used in previous studies as a proxy for past spring sea ice occurrence and as an indicator of wider palaeoenvironmental conditions for different regions of the Arctic over various timescales. The current study describes a number of analytical and palaeoceanographic developments of the IP25 sea ice biomarker. First, IP25 was extracted and purified from Arctic marine sediments. This enabled the structure of IP25 to be confirmed and enabled instrumental (GC-MS) calibrations to be carried out so that quantitative measurements could be performed with greater accuracy. Second, palaeo sea ice reconstructions based on IP25 and other biomarkers were carried out for a suite of sub-Arctic areas within the Greenland, Norwegian and Barents Seas, each of which represent contrasting oceanographic and environmental settings. Further, an evaluation of some combined biomarker approaches (e.g. the PIP25 and DIP25 indices) for quantifying and/or refining definitions of sea ice conditions was carried out. Temporally, particular emphasis was placed on the characterisation of sea ice conditions during the Younger Dryas and the Holocene. Some comparisons with other proxies (e.g. foraminifera, IRD) were also made. A study of a sediment core from Andfjorden (69.16˚N, 16.25˚E), northern Norway, provided unequivocal evidence for the occurrence of seasonal sea ice conditions during the Younger Dryas. The onset (ca. 12.9 cal. kyr BP) and end (ca. 11.5 cal. kyr BP) of this stadial were especially clear in this location, while in a study from the Kveithola Trough (74.52˚N, 16.29˚E), western Barents Sea, these transitions were less apparent. This was attributed to the presence of colder surface waters and the occurrence of seasonal sea ice both before and after this stadial at higher latitudes. Some regional differences regarding the severity of the sea ice conditions were also observed, although an overall general picture was proposed, with more severe sea ice conditions during the early-mid Younger Dryas and less sea ice observed during the late Younger Dryas. A shift in the climate towards ice-free conditions was recorded in northern Norway during the early Holocene (ca. 11.5 – 7.2 cal. kyr BP). Milder conditions were also observed during the Holocene in the western Barents Sea, with three main climate periods observed. During the early Holocene (ca. 11.7 – 9.5 cal. kyr BP), the position of the spring ice edge was close to the study area which resulted in high productivity during summers. During the mid-late Holocene (ca. 9.5 – 1.6 cal. kyr BP), sea ice was mainly absent due to an increased influence of Atlantic waters and northward movement of the Polar Front. During the last ca. 1.6 cal. kyr BP, sea ice conditions were similar to those of the present day. In addition to the outcomes obtained from the Norwegian-Barents Sea region, comparison of biomarker and other proxy data from 3 short cores from Kangerdlugssuaq Trough (Denmark Strait/SE Greenland) with historical climate observations allowed the development of a model of sea ice conditions which was then tested for longer time-scales. It is suggested that the IP25 in sediments from this region is likely derived from drift ice carried from the Arctic Ocean via the East Greenland Current and that two main sea surface scenarios have existed over the last ca. 150 yr. From ca. AD 1850 – 1910, near perennial sea ice conditions resulted in very low primary productivity, while from ca. AD 1910 – 1986, local sea ice conditions were less severe with increased drift ice and enhanced primary productivity. This two-component model was subsequently developed to accommodate different sea surface conditions that existed during the retreat of the Greenland Ice Sheet during the deglaciation (ca. 16.3 – 10.9 cal. kyr BP).

The Younger Dryas was the last period during which glaciers shaped large parts of the Scottish landscape. Reconstructing the palaeoclimate and glacial processes that operated during this time is crucial for the understanding of past atmosphere-cryosphere interactions and predicting future climate change. This thesis presents results from geomorphological and geological mapping in the NW Highlands of Scotland that have resulted in the reconstruction of a Younger Dryas ice cap. Reconstruction of equilibrium-line altitudes and palaeo-precipitation values suggest that the Scottish west coast was wetter than at present. Detailed sedimentological analyses of "hummocky moraines" allow the modes of moraine formation to be reconstructed in great detail and existing models to be tested. "Hummocky moraines" largely represent terrestrial ice-contact fans consisting of supraglacial debris flows and intercalated glaciofluvial units indicating an ice-marginal mode of formation. Different stages of deformation in these fans indicate highly dynamic glaciers that oscillated during retreat, partly or completely overriding previously formed landforms during readvances. Clast shape analyses reveal that debris was mostly subglacially derived and transported. The evidence is incompatible with a morphological model according to which the moraines could be formed by englacial thrusting. Comparison with modem glacial landsystems indicates the following similarities with Scottish Younger Dryas glaciers. Low winter temperatures are similar to those on Svalbard, the marginal response of Younger Dryas glaciers to temperate environments and the modes of deposition to less responsive debris-covered glaciers. High precipitation along the Scottish west coast probably suppressed continuous permafrost development and caused high mass turnover and very dynamic, dominantly temperate Younger Dryas glaciers. Only a narrow zone around the margins appears to have been frozen to the ground, aiding elevation of basal debris and rapid deposition near the snout. The specific climatic and glaciological conditions during the Younger Dryas appear not to have a single modem analogue.

Dryas iulia pertence à subfamília HeliconitIae e é uma borboleta que prefere voar ao sol, sendo comumente encontrada em clareiras, bordas de florestas e matas secundárias. Ovoposita em espécies de Passifloraceae preferindo, em Porto Alegre e arredores Passiflora suberosa e P. misera (PÉRICO & ARAÚJO, 1991). É abundante durante quase todo o ano, excetuando-se os meses frios de inverno, quando suas populações virtualmente se extinguem. Geralmente o maior tamanho populacional é registrado nos meses de abril e maio. Do ponto de vista genético, Dryas iulia apresenta populações grandes e uniformes; em termos de estrutura genética elas se mostram compatíveis com o modelo do isolamento pela distância. Estudos realizados por HAAG (1992), HAAG e cols., (1993) mostraram que os valores de FSTnão diferiam de zero para várias amostras ("populações") do Rio Grande do Sul. O componente devido ao endocruzamento (FIs) também não diferiu de zero, embora seu valor numérico fosse mais elevado do que o esperado. No presente estudo investigou-se amostras seqüenciais (equivalentes a quatro gerações sucessivas) da região de Águas Belas, município de Viamão, RS, quanto a polimorfismos enzimáticos e variação morfológica. Originariamente os critérios para escolha deste local, foram a detcção, em trabalhos anteriores, por HAAG (1992), HAAG e cols., (1993), de uma situação altamente sugestiva de associação não aleatória entre dois locos enzimáticos (EST e LAP) nesta população, além das medidas lineares realizadas.nas asas anteriores mostrarem que os indivíduos dessa população são em média maiores quando comparados com os de outras. As amostragens ocorreram em maio de 1992, junho de 1992, março de 1993 e maio de 1993, (I, 11,111e IV amostras respectivamente). Baseado nos dados de polimorfismo enzimático para os locos Mdhl, Mdh2, Pgml, Pgm2, Aatl, Aat2, Estl, Est2 e a-Gpdh, a população local de D. iulia de Águas Belas apresentou, nas quatro amostras, os respectivos valores de heterozigosidade média por loco por indivíduo (Ho): 0,076 Gunho/92), 0,097 (maio/92), 0,103 (março/92) e 0,122 (maio/92). O menor valor para este parâmetro ocorreu no inverno, provavelmente por perda de alelos raros devido ao acaso. A proporção de locos polimórficos (P) variou de 55% a 66% entre as referidas amostras, enquanto que o número de alelos por loco (Ae), variou de 1,0 a 5,0 , com uma média de 2,36 alelos por loco; o número efetivo de alelos variou de 1,0 a 2,2 alelos por loco. Quase todos os locos apresentaram-se em equilíbrio de Hardy-Weinberg, exceto Pgnil e Pgm2, cujos desvio foram significativos, (p
