Species that become naturalized in a new geographical range, subsequently multiply and spread, and persist to the detriment of resident communities, are known as alien invasive species. Two aspects of species invasion – spread and ecological impact – were examined using Lantana camara L. (henceforth lantana) as the study system, specifically in the context of a seasonally dry tropical forest ecosystem of the Mudumalai Wildlife Sanctuary and National Park. Lantana is a thicket-forming woody shrub of South and central American origin, which is now widespread across the tropics. The thesis is divided broadly into two parts -the first part examines the influences of environmental factors on the distribution and spread of lantana while the second part focuses on the effects of lantana on the distribution, survival and growth of native woody species. Much of the work presented in this thesis was conducted within a 50 ha permanent plot (the Mudumalai Forest Dynamics Plot, MFDP hereon) in Mudumalai, chiefly because the history of invasion by lantana has been recorded here since 1989. The influence of changing resources on lantana invasion was explored at two scales -small spatial but fine temporal scale in the MFDP and at the level of the landscape. Available data on an 18 year chronosequence of changes in the qualitative density of lantana from the MFDP and field studies between the years 2009 and 2010 were used to determine the environmental correlates of lantana spread in time and space. It was found that biotic factors such as the presence of the shrub Helicteres isora and abiotic factors such as proximity to drainages and the combination of fire and drought promoted the intensification of lantana invasion in time while proximity to streams, higher total annual rainfall and low fire frequency contributed to lantana invasion at the landscape level. The impacts of lantana on the seedlings of native woody species were assessed in 10m x 10m plots within the MFDP. An initial enumeration of 60 such plots revealed that animaldispersed, dry forest habitat preferring species were most affected by the presence of dense lantana. A follow-up study comprising of growth and survival measurements made on 1105 seedlings over two years (2008-2010) further confirmed that dry forest preferring species were most affected by the presence of dense lantana and that this response at the community level was most likely influenced by the most abundantly sampled species in this habitat preference guild – Catunaregam spinosa. In conclusion, while the environmental correlates of lantana most likely promoted its invasion, only certain guilds of native species seemed to be negatively affected by the presence of lantana.

Lantana camara has medicinal properties and it has been used in folk medicine. The aim was to verify the effect of a lantana extract on the labeling of blood constituents with 99mTc, and to evaluate the effect of an aqueous extract of Lantana camara on the morphology of RBC withdrawn from Wistar rats. The results showed that lantana extract has decreased the fixation of radioactivity on the IF-P. This effect was not observed in the BC compartment and in IF-BC. The BC-%ATI was decreased in all concentrations tested when the BC was washed. The osmotic fragility assay and morphological analysis were carried out. In presence of the extract, the data obtained indicated that (i) an increase of the hemolysis and (ii) modifications on the morphology of RBC. These effects of the Lantana camara could be associated with some pharmacological properties of the chemical compounds of this studied extract / Extratos de plantas medicinais s?o utilizados amplamente em todo o mundo. Entretanto, efeitos biol?gicos associados aos mesmos n?o t?m sido investigados exaustivamente. Atrav?s do uso de suas folhas e flores a Lantana camara (Cambar? de espinho) tem sido usado para tratamento de v?rias doen?as na medicina popular. O presente estudo teve como objetivo verificar o efeito do extrato desta planta na marca??o de constituintes sang??neo com tecn?cio 99m, bem como a morfologia de hem?cias de ratos Wistar. Os resultados mostraram que o extrato de Lantana camara acarretou uma diminui??o de fixa??o de radioatividade na fra??o insol?vel do plasma. Este efeito n?o foi observado na c?lula e nem na fra??o insol?vel da c?lula. O percentual de atividade teve diminui??o em todas as concentra??es quando as c?lulas foram lavadas, o que n?o foi observado com o controle. O extrato estudado aumentou a fragilidade osm?tica das hem?cias e modificou a morfologia dessas c?lulas. Os efeitos do extrato de Lantana camara podem estar associados a algumas propriedades farmacol?gicas de componentes qu?micos do extrato estudado. O estudo teve car?ter multidisciplinar com a participa??o das seguintes ?reas do conhecimento: Radiobiologia, Bot?nica, Fitoterapia e Hematologia

A tese estuda a participação do episcopado brasileiro no Concílio Vaticano II, convocado einaugurado pelo Papa João XXIII (1959-1963), continuado e concluído por Paulo VI (1963-1965): etapa antepreparatória (1959-1960), com as respostas (vota) dos bispos e prelados à consulta romana; etapa preparatória, com os trabalhos nas comissões preparatórias (1960-1962) e etapa conciliar, nos seus quatro períodos, com as intervenções na Aula Conciliar ou depositadas por escrito (1962-1965). Analisa outros aspectos da vida e atividades do episcopado brasileiro em Roma: local de moradia e trabalho; pontos de apoio; inserção nas redes de articulação formadas antes e durante o Concílio; promoção das assim chamadas Conferências da Domus Mariae, Mensagens ao povo brasileiro; elaboração do Plano de Emergência da Igreja do Brasil (PE –1962) e encaminhamento da recepção do Concilio, com o Plano de Pastoral de Conjunto (PPC - 1965). Conclui com a prosopografia de todos os bispos e prelados brasileiros que tiveram direito, nem sempre exercido, de participarem das diversas etapas do Concílio; a bibliografia e um caderno iconográfico. / The thesis studies the participation of the Brazilian episcopate in the Second Vatican Council, convoked and inaugurated by Pope John XXIII (1959-1963), continued and concluded by Paul VI (1963-1965): the pre-preparatory phase (1959-1960), with the replies (vota) of the bishops and prelates to the Roman consultation; the preparatory phase, with the work done in the preparatory commissions (1960-1962) and the conciliar phase, with its four periods, and with the interventions in the Plenary Sessions of the Council or submitted in writing (1962-1965). The thesis also analyses other aspects of the life and activities of the Brazilian episcopate in Rome: where the bishops stayed, where they found support; how they were linked into the various net-works that were formed before and during the Council; the promoting of the events that went under the title of the Domus Mariae Conferences, of the Messages to the Brazilian People; the elaboration of the Emergency Plan for the Church in Brazil (PE – 1962) and the steps taken to ensure the reception of the Council, with the Joint Pastoral Plan (PPC – 1965). It finishes with a prosopography of all the Brazilian bishops and prelates who had the right, not always exercised, of participating in the various stages of the Council; a bibliography and iconography.

O presente trabalho tem por objetivo propor aproximações entre os autores Câmara Cascudo e Oscar Ribas. O primeiro pertencente ao sistema literário brasileiro e o segundo ao angolano. Buscamos a comparação entre ambos, considerando as semelhanças entre seus percursos. Ao longo de suas carreiras, os autores dividiram-se entre a produção literária e a pesquisa folclórica. A proposta que executamos apropria-se do conceito de macrossistema literário defendido por Benjamin Abdala Júnior. Em sua perspectiva, macrossistema é definido pelos contatos que podem ser estabelecidos entre os sistemas literários nacionais no contexto das literaturas de língua portuguesa. Nosso estudo centra-se sobre dois romances: Canto de muro (1959) de Câmara Cascudo e Uanga (feitiço) (1951) de Oscar Ribas. A análise destas obras nos permite apreciar textos fracionados entre o fazer literário e o compromisso com a divulgação de dados de pesquisa. A dualidade nas carreiras dos intelectuais é espelhada na composição de seus romances. Realizamos também uma leitura do livro de ensaios Made in África (1965) de Câmara Cascudo, no qual nos deparamos com um Cascudo leitor de Oscar Ribas e preocupado com os matizes africanos da cultura brasileira. / The present work aims to propose some relations between the writers Câmara Cascudo and Oscar Ribas considering the similarity in their literary journey, the former belonging to the Brazilian literary system and the latter to the Angolan literary system. During their careers, those writers dedicated themselves to the literary production as well as the research on folklore. The study approach is the concept of literary macrosystem defended by Benjamin Abdala Júnior, which is defined by the contacts that can be established among the national literary systems in the context of Portuguese-language literatures. It focuses on two novels, Câmara Cascudo\'s Canto de muro (1959) and Oscar Ribas\'s Uanga (feitiço) (1951). The analysis of both works allows us to appreciate texts parceled into the literary making and the commitment to publishing their researches. That dualism in both intellectual careers is reflected in the composition of their novels. The reading of Câmara Cascudo\'s essay book, Made in África (1965), has allowed us to see Câmara Cascudo as a reader of Oscar Ribas\'s works and a writer concerned about the African hue of Brazilian culture.

abstract: ABSTRACT Moving beyond Form: Communicating Identity through Dance chronicles the journey of investigating my personal creative process in dance. This was a search for strategies to empower myself creatively, enabling me to move beyond the limitations of a prescribed form or style of dance and communicate ideas that were relevant to me. But on a deeper level, it was an exploration of my capacity to self-define through movement. The challenge led me to graduate school, international study with world-renowned choreographers and to the development of a holistic creative practice, Movement to Meaning. The aim of this creative practice is to express internal awareness through movement, thereby enabling the mover to dance from an internal reference point. In my research, I utilized Movement to Meaning to re-contextualize Sandia, a traditional-based dance that is indigenous to various Mande subgroups in West Africa. This project culminated in a choreographic presentation, Ten For Every Thousand, which was performed in October 2010 at the Nelson Fine Arts Center at Arizona State University in Tempe, Arizona. / Dissertation/Thesis / M.F.A.

Este estudo investigou a ecologia de vespas parasitóides ocorrentes em galhadores Schismatodiplosis lantanae Rübsaamen, 1916 (Cecidomyiidae) em folhas de Lantana camara L. (Verbenaceae). Dessa forma, o primeiro artigo trata da ecologia comportamental da vespa parasitóide Torymus sp. (Torymidae, Hymenoptera), onde foi avaliado como as fêmeas dessa espécie defendem seu recurso de oviposição no hospedeiro. Foi analisado mudanças no comportamento devido à presença de outra fêmea coespecífica no local, ser residente do recurso, tamanho das vespas e número e tamanho das galhas através de filmagens dos experimentos realizados em laboratório. Com esse trabalho observou-se que fêmeas mudam seu comportamento quando estão na presença de um competidor em um território com hospedeiros. A estratégia de ataque foi através da ameaça, na qual suas antenas e asas são levantadas para expulsar o competidor do local. A probabilidade de haver ataques a fêmeas coespecíficas depende do tempo prévio de exploração da galha e da permanência na folha. O interesse no hospedeiro pelas invasoras foi a principal causa de conflitos com a residente. O segundo artigo trata da diversidade de vespas parasitóides e de um ciclo parasita-hospedeiro observado no período de um ano no sistema de L. camara. Foram encontradas nove espécies de vespas parasitóides, divididas em quatro famílias. Ocorreu um ciclo no parasitismo das espécies de vespas sobre seu hospedeiro no ano amostrado, podendo ser observado que são mais elevadas nos meses de Julho a Janeiro e a sobrevivência do hospedeiro foi maior nos meses de Fevereiro a Maio. As estratégias comportamentais de fêmeas de uma vespa parasitóide em relação a seus hospedeiros foram analisadas, bem como um sistema composto de diversas espécies parasitóides e sua variação no tempo. Estas observações podem contribuir para um melhor entendimento da ecologia comportamental e do padrão temporal das vespas parasitoides, e também para futuros programas de controle biológico mais eficientes. / We investigated the ecology of parasitoid wasps attacking Schismatodiplosis lantanae Rübsaamen, 1916 (Cecidomyiidae) galls on leaves of Lantana camara L. (Verbenaceae). The first article discusses the behavioral ecology of the parasitoid wasp Torymus sp. (Torymidae, Hymenoptera), reporting how their females defend oviposition resources on the hosts, changing their behavior due to the presence of a conspecific female in the patch. The identity of the wasp (resident or intruder) on the resource, female size and number and size of galls in the patch were factors studied through analysis of the behaviors revealed by video recordings of the laboratory experiments. Females change their behavior in the presence of a competitor in a territory with hosts. The strategy was to threat, raising their antennae and wings to expel the competitor of the patch. The probability of an attack on a conspecific females depended on the host exploitation time and time spent on the galled leaf. Interest in host by intruders was the main cause for conflicts. The second article reports the diversity of parasitoid wasps and a host-parasite cycle during one year period in the L. camara leaf galls system. Nine parasitoid wasp species were found, divided in four families. A cycle between parasitism and host survival was found during the sampling period. Wasp species are more abundant from July to January and host survival higher from February to May. Behavioral strategies of parasitoid wasp females toward their hosts and conspecifics have been elucidated, with the system composed of different parasitoid wasp species apparently going through an annual cycle of parasitism rate. These observations may contribute to a better understanding of parasitoid behavioral ecology and host-parasitoid dynamics, enabling more efficient future biological control programs.
