Currently are known 24 species assigned to six genera: Benoistella Uvarov, 1939; Mexiacla Gorochov, 2007; Oaxacla Gorochov, 2007; Paragryllus Guérin- Méneville, 1844; Rumea Desutter, 1988; and Silvastella Desutter- Grandcolas, 1992. In this paper new taxa from the Brazilian Central Amazonia are described. The genus Rumea is reported for the first time from this region, represented by three new species from the Central Amazonian: R. zebra sp. nov., R. manauensis sp. nov. and R. tigris sp. nov. Also two new genera are described: Marciela gen. nov., including M. longipes sp. nov. from Brazil and M. crybelos (Nischk & Otte, 2000) comb. nov. from Ecuador; and Sperberus gen. nov. including only S. arboricolus sp. nov. The morphology of the male genitalia of the Rumea species is discussed and a new interpretation is proposed. For the illustration of the genitalia of males and females a photographic technique was used: the structure was immersed in glycerin and photographs were taken on different levels of focous. For the construction of the final images the free software CombineZM was used. The biogeography of the Paragryllini is discussed based on the known distribution of the species. This study contributes to the knowledge of the group, increases its geographical distribution, and may serve as a starting point for future research on the Paragryllini in Brazil. / Paragryllini Desutter é uma tribo Neotropical com espécies distribuídas do sul do México até o Brasil. Atualmente são conhecidas 24 espécies subordinadas a 6 gêneros: Benoistella Uvarov, 1939; Mexiacla Gorochov, 2007; Oaxacla Gorochov, 2007; Paragryllus Guérin-Méneville, 1844; Rumea Desutter, 1988; e Silvastella Desutter-Grandcolas, 1992. Nesta dissertação são descritos novos táxons de Paragryllini da Amazônia Central brasileira. Faz-se o primeiro registro do gênero Rumea para esta área, com a descrição de três espécies novas: R. zebra sp. nov., R. manauensis sp. nov. e R. tigris sp. nov.. Também são descritos dois gêneros novos: Marciela gen. nov., que inclui Marciela longipes sp. Nov. do Brasil e Marciela crybelos (Nischk & Otte, 2000) comb. nov. do Equador; e Sperberus gen. nov. incluindo unicamente Sperberus arboricola sp. nov. Para as espécies do gênero Rumea, discutem-se as características morfológicas da genitália dos machos e se propõe uma nova interpretação da dessa estrutura. Para ilustrar a genitália tanto dos machos quanto das fêmeas, desenvolveu-se uma técnica de fotografia: a estrutura era inmersa em glicerina e eran tiradas fotografias em diferentes níveis de foco. Para a construção da fotografia final usou-se o software livre CombineZM. Discutem-se alguns aspectos biogeográficos baseados na distribuição conhecida das espécies de Paragryllini. Este estudo proporciona um aporte para o conhecimento do grupo, já que se amplia sua dibribuiçao geográfica, e puede servir como um punto de partida para futuras pesquiças sobre os Paragryllini no Brasil.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Esta dissertação levanta uma análise comparativa dos processos políticos que antecederam a construção de duas pontes transnacionais nas Américas: a ponte sobre o Rio Tacutu, que liga as cidades de Lethem (Região 9, Guyana) e Bonfim (Roraima, Brasil); e a ponte sobre o Rio Hondo, que liga as cidades de Santa Elena (Corozal, Belize) e Subteniente López (Quintana Roo, México). Enquanto isso, o estudo inserese no corpo mais amplo de pesquisas que analisam o processo de integração das Américas através do uso de infraestrutura física. Além disso, a pesquisa aborda a maneira em que poderes emergentes usam infraestrutura para propósito de projeção de poder regional nos seus entornos geopolíticos, particularmente, em relação aos seus vizinhos contíguos menores. Esta análise realiza-se no contexto histórico do reconhecimento da necessidade de fomentar integração entre os países do sul global e de países de tradições coloniais diferentes; e mais ainda, visa alcançar essa meta com o uso da infraestrutura física. Metodologicamente, é um estudo interpretativo quantitativo das fontes bibliográficas e discursos executivos, utilizando o método comparativo para deduzir modos de interação entre dois poderes emergentes latinoamericanos e dois países relativamente pequenos e isolados do Caribe anglófono. Pode-se concluir que as duas pontes foram construídas e inauguradas dentro de projetos mais amplos para integração regional, promovidos pelo México e Brasil, para as regiões imediatas de influência geopolítica, facilitado por fortes vínculos bilaterais históricos no campo de segurança de território; e completado pela transição contemporânea dos países caribenhos na busca para novos parceiros internacionais, frente à perda de viabilidade de vínculos tradicionais. / This dissertation carries out a comparative analysis of the political processes leading up the construction of two transnational bridges in the Americas; these are the Takutu River Bridge linking Lethem, Region 9, Guyana and Bonfim, Roraima, Brazil; and the Hondo River Bridge linking Santa Elena, Cozoral, Belize and Subteniente López, Quintana Roo, Mexico. In so doing, the study is inserted in a wider body of researches that analyse the process of integration in the Americas through the use of physical infrastructure. The research further highlights how emerging powers use infrastructure as a means of regional power projection in their geopolitical spaces, particularly as it pertains to smaller contiguous neighbours. This analysis takes place in the historical context of countries of the global south and of different colonial traditions, recognising the need to foster integration, and achieve advancement in this regard through infrastructure. Methodologically, it is an interpretive qualitative study of bibliographical sources and executive speeches, using the comparative method to deduce modes of interaction between two emerging Latin American powers and two relatively small and isolated continental countries of the Anglophone Caribbean. It may be concluded that the two bridges were successfully constructed and inaugurated as part of wider projects for regional integration fostered by Mexico and Brazil for their regions of immediate geopolitical influence, and aided by historically strong bilateral relations in the area of territorial integrity and further, the contemporary transitioning in the search by Caribbean countries for new international partners as old linkages become less viable.

Esta operação fez parte de um convênio firmado entre a Marinha Americana e a Marinha Brasileira, cujo objetivo era investigar o Oceano Atlântico Sul, especialmente a área onde se estende a província fisiográfica da Cadeia Mesoatlântica. Com o objetivo de estudar a Zona de Fratura Dupla Bode Verde, e assim conhecer melhor esta feição tão marcante no fundo oceânico e margem continental, foram tratados e interpretados os dados batimétricos, gravimétricos e magnéticos colhidos na operação anteriormente citada. A análise dos dados batimétricos permitiu uma definição para esta zona de fratura, com o seu caráter duplo marcado pela presença de duas calhas contínuas, paralelas entre si, e separadas por um alto que tem o seu próprio "rift-valley". As anomalias gravimétricas encontradas confirmam o caráter duplo, com os dois mínimos observados correspondendo às duas calhas da fratura. Estas calhas separam um bloco crustal de aproximadamente 40 km de largura. Com base nos dados gravimétricos, foram construídas nove seções crustais sobre a zona de fratura, que permitiram observar que a interface crosta-manto sofre um afinamento crustal embaixo das paredes da fratura. Esta interface, que encontra-se normalmente a uma profundidade de 8-9 km, passa a atingir profundidades de 5.5-6.0 km abaixo das paredes da fratura, com a crosta apresentando uma espessura de 2.0 km nestas partes. Este afinamento crustal é causado pela subida de material do manto. A extensiva alteração hidrotermal que ocorre na depressão central da fratura, pode ser a responsável pelo menor afinamento crustal observado nesta parte da zona de fratura. Para a interpretação dos dados magnéticos, foi usada uma escala de tempo de polaridade magnética entre o Cretáceo Inferior e o Cenozóico, e uma taxa de espalhamento oceânico de 2.0 cm/ano. Para a camada de basalto, que é responsável por parte das anomalias magnéticas observadas, foi usada uma espessura média de 0.5 km. Nas paredes da zona de fratura, ocorre uma diminuição na espessura desta camada, havendo uma interrupção da mesma na depressão central da fratura. / In January 1980, the CENTRATLAN Project Bode Verde I was conducted by collecting geophysical and geological data at the central portion of the Middle Atlantic Ridge, south of Ascensão Island. This research was done within an agreement between the US-American and Brazilian Navy. With the objective to describe the geology of the Bode Verde fracture zone and to understand the origins of this feature on the ocean floor and continental margin, bathimetric, gravimetric and magnetic data were collected. The analysis of the bathimetric data allowed to describe this feature as a doubled fractured zone, marked by two continuous troughs, parallel to each other, separated by a high with its own rift-valley. The gravimetric anomalies confirm this double feature, with the two observed gravimetric minimum corresponding to the two troughs of the fracture zone. These troughs separate a crustal block of approximately 40 km width. Based on gravimetric data it was possible to construct nine crustal sections of the fracture zone. They permitted to observe a thinning of the crust-mantle interface beneath the fracture walls. The interface crust-mantle that usually has a depth of 8-9 km, is only 5.5-6.0 km deep beneath the fracture walls with a crust thickness of about 2.0 km. The crustal thinning is caused by the ascent of mantle material. The hidrothermal alteration in the central trough of the fracture can be responsible for the minor crustal thinning observed in this part of the fracture zone. For the interpretation of the magnetic data was used a time scale of magnetic polarity between the Lower Cretaceous and Cenozoic and a spreading rate of the ocean floor of about 2.0 cm/year. For interpretation a thickness of 0.5 km was estimated for the basalt layer, which is responsible for the observed magnetic anomalies. lts thickness decreases in the fracture walls, being interrupted at the central trough fracture.

La resolución elegida para desarrollar el presente trabajo es la sentencia de la Corte Internacional de Justicia del 18 de diciembre de 2020, acerca de su competencia en el caso de la validez y efecto vinculante del Laudo Arbitral del 3 de octubre de 1899, que delimitó la frontera entre la hoy República Cooperativa de Guyana (en adelante, “Guyana”) y la hoy República Bolivariana de Venezuela (en adelante, “Venezuela”), en el marco de la controversia de éstos respecto del río Esequibo y su orilla por el lado Este. La Corte Internacional de Justicia, a través de su sentencia, se declaró competente para conocer la demanda planteada por Guyana, toda vez que consideró el origen voluntario del sometimiento de las partes a su jurisdicción en el Acuerdo de Ginebra de 1966, así como sostuvo que la controversia se encontraba cristalizada en un tratado vigente. La corte emitió esta resolución a pesar de la manifiesta negativa de Venezuela de participar en el proceso por considerar que no expresó su consentimiento para someter la controversia a la jurisdicción de la Corte. La sentencia en cuestión plantea un debate en torno al consentimiento del Estado y si acaso Venezuela lo expresó cuando aceptó que el Secretario General de las Naciones Unidas decidiera el medio de solución de controversias

This thesis is an ethnographic account of how the Wapichannao, who are situated in the Rupununi of Guyana perceive themselves within the nation-state. This is also an account of how non-Amerindian Guyanese envisage Amerindians as ‘past' peoples. Hence, distinctions are made between Amerindian and non-Amerindian—us vs. them—where both identities become placed as opposite poles within a continuum. Emphasis is placed on the shifting relationships between these poles, but more specifically, the cultural paradigm through which these relationships are made possible. This paradigm, I suggest, may be understood in terms of polarities of difference, with regard to which Amerindians are constantly ambiguating/negotiating, disjoining, and resignifying notions of ‘who they are'. This thesis evidences this paradigm through an ethnography of some of those aspects of Wapichannao culture—village work, the shop, joking activity, culture shows—that are considered to be traditional on the one hand, and modern on the other. In doing so, an incongruous trend emerges, on which makes the classic imagery of Amerindian ontological homogeneity much more complex. Therefore, this thesis moves from the more traditional aspects of Wapichannao culture towards the nation-state, in order to take into account aspects of Amerindian experience absent from classic ethnographic accounts.

A arqueologia amazônica passou por uma série de mudanças no entendimento sobre a natureza da ocupação pré-colonial desta região ao longo dos anos. Há hoje sólidas bases para perceber que a Amazônia, tanto no passado quanto no presente, é extremamente heterogênea, indo além do que colocam os modelos dicotômicos que historicamente influenciaram a arqueologia amazônica. Neste contexto, esta tese busca descrever uma longa história indígena em uma região da Amazônia, o litoral da Guayana, mais especificamente uma região compreendida entre foz do Amazonas até a foz do rio Orinoco, parte da conhecida historicamente \"Costa Selvagem\". Uma das perguntas fundamentais da tese, que busco perseguir através da descrição desta longa história, é qual a origem e natureza dos monumentos e das cerâmicas altamente elaboradas encontradas associadas a eles nesta região a leste da Guayana. Desta forma aqui apresentaremos uma síntese da ocupação, advinda dos novos dados obtidos nos últimos anos, iniciando com os primeiros ocupantes da Guayana Oriental até uma reconfiguração ética ocorrida na região a partir dos séculos XVIII e XIX D.C. Buscamos desta forma aqui alinhavar relações possíveis entre diversos elementos presentes na cultura material da região, monitorando continuidades e mudanças nas relações entre objetos, lugares e pessoas. / Branco.

La Guyane présente la fécondité la plus élevée de l’ensemble des régions françaises et également des autres territoires d’Amérique du Sud et de la Caraïbe : 3,3 enfants par femme estimés en 2018.Cette thèse propose une analyse des principaux déterminants de la fécondité en Guyane, notamment aux zones frontalières, les plus natalistes. Ce travail s’appuie sur les résultats d’une enquête par questionnaire menée auprès de femmes et d’hommes résidant dans quatre communes frontalières avec le Suriname, à l’ouest, et une commune frontalière avec le Brésil, à l’est. Un complément a été réalisé dans le municipio d’Oiapoque, au Brésil, à la frontière guyanaise.Cette thèse présente tout d’abord le contexte historique et ethnologique qui préside à la composition actuelle de la population de Guyane. Puis elle examine les caractéristiques sociologiques de la société guyanaise d’aujourd’hui, et notamment des communes frontalières, où les populations sont économiquement et socialement précaires, peu instruites et fréquemment migrantes.Explorant comment interagissent les déterminants socio­économiques, le niveau d’utilisation de la contraception, l’âge à la première maternité, le nombre actuel d’enfants et les normes de fécondité, les résultats de la recherche montrent qu’il y a deux situations bien distinctes : à l’est, pour les femmes d’origine brésilienne, la transition démographique est pratiquement terminée ; à l’ouest, pour les femmes bushinenge, elle ne fait que commencer.Cette recherche repose sur l’hypothèse que le moment présent se situe, pour les femmes bushinenge, à la charnière entre fécondité non régulée et fécondité régulée. / French Guiana has the highest fertility level of all French regions and of other countries in South America and the Caribbean: on average, 3.3 children per woman estimated in 2018.This thesis aims to analyze the main determinants of fertility in French Guiana, particularly in border areas which present high birth rates. It draws on the results of a survey of women and men by questionnaire residing in four municipalities bordering Suriname in the West, and a border town with Brazil in the East. An additional survey was conducted in the municipality of Oiapoque in Brazil at the Guyanese border.Firstly, this thesis presents a historical and ethnological background that determine the current composition of the population of Guyana. Secondly, it examines the sociological characteristics of today’s Guyanese society, notably border municipalities where populations are economically and socially precarious, poorly educated and frequently migrating.Exploring the interaction between socioeconomic determinants, the level of contraceptive use, age at first birth, current number of children and fertility standards, our research findings show two different situations: demographic transition is almost complete in the East for women of Brazilian origin while in the West, for bushinenge women, demographic transition is just beginning.This research is based on the assumption that currently, fertility of bushinenge women is at a transition period between unregulated and regulated fertility.

Previous research shows that socio-cultural factors play an important role in determining the outcomes of natural resource conservation. Conservationists have discovered that when such factors are not properly incorporated from the earliest planning stages, projects are often less successful than hoped and at times outright failures. Thus, several core values that vary among cultures were studied to examine their relationships to natural resources and conservation. This study investigated the relationships between natural resources and conservation and the 3 value orientations individualism, collectivism, and locus of control and socio-demographics in the North Rupununi, Guyana. Quantitative and qualitative data were collected in 5 villages (Annai Central, Apoteri, Rewa, Aranaputa, and Wowetta) via participant observation and mostly structured interviews of 167 local residents. Field research took place from January to November 2008, and interviews occurred from July to October of the same year. Analysis indicates the following results for this sample. Neither the individualism measurement used in this study not the locus of control scale showed many statistically significant associations, but some interesting patterns and trends appear in the case of locus of control. In contrast, the collectivism scale showed associations to several of the natural resource items. The main conclusions from the study are that to promote more successful conservation, professionals need to focus on several factors that promote more effective communication and negotiation. Developing equity among participants; empowering people through their own knowledge, influence, and options; establishing respect by and for all parties; co-creating a common mental model among the parties; and fostering the competence and confidence of all parties to actively participate in the negotiations are key to success. This can be especially tricky in cases in which the various parties come from different socio-cultural backgrounds, such as in the case of Western scientists working with remote indigenous peoples. Coming to a shared mental model and feelings of true equity among the parties is even harder then because the disparate backgrounds make common understanding difficult at best. However, it is that much more necessary when common backgrounds are absent. In such cases, a well-trained, culturally sensitive, and neutral facilitator can be the most useful tool to help co-create the right circumstances for authoring solutions which foster natural resource conservation that can succeed.

Guyana’s REDD+ model features the placement of almost all of the country’s rainforest under long-term protection in return for monetary incentives that will be used to move the country along a low carbon development trajectory. It is a model of forestry preservation and sustainable development that the Government of Guyana is developing in partnership with the Government of Norway. This model of development is part of the global climate change mitigation scheme, Reducing Emissions from Deforestation and Degradation plus (REDD+). REDD+ is a series of initiatives focused on/in developing countries seeking to diminish carbon dioxide emissions caused by deforestation and degradation, processes recognized as being one of the leading causes of climate change. It aims to dramatically reduce these emissions by creating an incentive mechanism that will pay developing countries to halt destructive processes that lead to deforestation and degradation. Guyana’s REDD+ model has significant implications for Amerindians who occupy the forested regions of Guyana, where most REDD+ related activities are scheduled to take place. Although this model is developing in a context where the legal and political regime governing Amerindians is weak, the treatment of Amerindians in REDD+ development leaves much to be desired in terms of both recognition and protection of important human rights. This Thesis reviews Guyana’s pioneering REDD+ model to show that it is failing to safeguard Amerindian rights recognized under international human rights law. Within the framework of the law, it argues that Guyana’s actions are contrary to its international obligations regarding indigenous peoples. Appropriate measures that should be adopted by Guyana to safeguard Amerindian rights are explored and proposed in this thesis. Possible measures that can be adopted by Norway, the World Bank, and the international community to motivate Guyana to undertake reforms are also examined.
