Territorialidade e ecologia reprodutiva de Formicivora littoralis (Thamnophilidae) na Restinga da Massambaba, RJ

A distribuição espacial dos indivíduos é decorrente da presença e ausência de microhábitats adequados, sendo aqueles que se estabelecem nas melhores manchas favorecidos pela seleção natural. A aquisição de um território permite a manutenção do indivíduo e o sucesso reprodutivo. A reprodução é considerada de alto custo energético, pois há deslocamento dos recursos para a manutenção de uma prole em vez de serem incorporados no crescimento individual. Investir em uma prole não significa alcançar o sucesso reprodutivo. O sucesso reprodutivo pode ser afetado, por exemplo, por eventos de predação, disponibilidade de alimento e cuidado parental. Este último pode ser realizado por ambos os membros do par reprodutor ou por apenas um deles. A deserção do cuidado parental por um dos sexos pode ser uma resposta à cópulas extra-par. Formicivora littoralis tem distribuição muito restrita. É a única espécie de ave considerada endêmica de restinga e se encontra ameaçada de extinção, embora seja localmente abundante. O presente estudo teve como objetivos: 1) estimar os tamanhos de territórios e compara-los entre estação reprodutiva e não reprodutiva; 2) testar a influência do tamanho dos indivíduos e quantidade de vizinhos no tamanho do território; 3) descrever ninhos, ovos, filhotes e determinar o sucesso reprodutivo; 4) quantificar o cuidado parental; 5) desenvolver marcadores moleculares de microssatélites para determinar paternidade. Para os indivíduos capturados e marcados individualmente, foram obtidas amostras de sangue e medidas morfométricas (tarso, asa, cauda, comprimento total), além do peso. Os tamanhos dos territórios foram estimados pelo método do mínimo polígono convexo (unindo pontos onde machos foram registrados vocalizando). A densidade foi estimada com base no tamanho dos territórios. Aspectos da reprodução foram acessados por meio de busca mensal por ninhos e acompanhamento destes por dois dias consecutivos. Foram obtidas as taxas de predação e a quantificação do cuidado parental. Para a paternidade foram utilizados sete marcadores de microssatélites, desenvolvidos para este fim. Formicivora littoralis possui território pequeno (0,008 a 0,32ha), que varia de acordo com a estação (menor na estação reprodutiva). O tamanho do território não foi relacionado com o tamanho do indivíduo, mas apresentou resultado significativo quando comparado com a quantidade de territórios vizinhos, mostrando ser menor quanto maior o número de vizinhos. A espécie apresentou elevada densidade (0,53 a 1,15 indivíduos/km2). Com relação à reprodução, ninhos tem o formato de cesto aberto onde foram postos no máximo dois ovos. Os filhotes nasceram sem penas. A razão sexual no ninho foi igual em ambos os sexos. A taxa de predação foi elevada na fase de incubação quando comparada à fase no ninho após a eclosão. O cuidado parental (durante a incubação e com os filhotes) foi realizado pelos dois sexos, sem diferenças na proporção do investimento realizado. Dos nove ninhos analisados, todos contiveram pelo menos um ninhego proveniente de fertilização extra-par. Um total de 81,2% dos ninhegos (13 em 16) não foram prole biológica do macho do par reprodutor que realizava o cuidado parental e que se encontrava pareado socialmente com a fêmea. Essa taxa foi a mais elevada entre os estudos já realizados nos neotrópicos

Entre a avenida Luís Guaranha e o Quilombo do Areal : estudo etnográfico sobre memória, sociabilidade e territorialidade negra em Porto Alegre

Essa dissertação é resultado de um estudo etnográfico desenvolvido junto aos moradores da Avenida Luís Guaranha, região central de Porto Alegre/RS. Esta comunidade, reivindicando-se como reminiscência viva do Areal da Baronesa - antigo território negro paulatinamente descaracterizado durante o séc. XX – se auto-reconhece como remanescente de quilombo, buscando assegurar o direito de permanência no local que ocupa, ao afirmar que teve origem nas senzalas da Chácara da Baronesa do Gravataí. Aborda-se esta situação de resgate das origens por parte da comunidade, explorando as tensões e conflitos envolvidos na reconstrução das identidades do grupo, processo que torna manifesto o caráter fragmentário das memórias, das relações de pertencimento e territorialização – e, portanto, das formas culturais - em nosso meio social. Tomando-se a cidade como objeto temporal (marcado por processos de destruição criativa, gentrificação e segregação das populações pobres e afro-descendentes), trabalha-se o fenômeno das transformações urbanas sob o prisma da memória coletiva de seus habitantes. A temática dos remanescentes, no caso deste estudo, emerge como mecanismo de garantia de direitos, mas também de construção de sentidos e significações atrelados aos nichos urbanos.

Territorialidade negra urbana a morfologia sócio-espacial dos núcleos negros urbanos segundo a herança histórica comum

O trabalho tem como objetivo caracterizar a territorialidade negra urbana através da análise da morfologia sócio-espacial dos núcleos negros considerando que a estruturação sócio-espacial de territórios negros na cidade pode ser compreendida a partir da analogia entre os assentamentos negros estabelecidos na África e Brasil, evocando uma herança histórica comum. Estão inseridas nessa abordagem as áreas remanescentes de quilombos e territórios negros espontâneos - os redutos negros da periferia. A motivação para a realização da pesquisa surge do interesse em verificar a herança morfológica das configurações étnicas negras na forma urbana das cidades brasileiras. Estuda-se o fenômeno de ocupação territorial dos grupamentos étnicos negros urbanos em duas vertentes concomitantes: histórica e sócio-espacial explorando a possibilidade de apreendê-los morfologicamente a partir de propriedades topológicas associadas a significados sociais tendo na leitura de plantas o elemento essencial da análise. Os territórios negros urbanos são registros configuracionais que ganham “sentido” através de figuras conceituais que podem ser “decodificadas” em referências simbólicas. Os graus de intensidade em que se é verificada a africanidade estão intrinsecamente ligados aos conceitos de territorialização, desterritorialização e reterritorialização, princípios norteadores fundamentais na formação de sistemas simbólicos sócio-espaciais de grupos étnicos negros contemporâneos.

Quilombo urbano maloca: territorialidade e ressignificação de processos identitários

Currently in the social sciences the question of self-identity and its meanings, absorb as a central objective aspects that concern analysis of an imaginary (re) constructed from processes of identity affirmation. Ethnic discourse in the consolidation of social boundaries (re) assemble a social policy apparatus able to claim their belongings concerning his ancestry, as well as the interpretation of the meanings given to their territory by any group. This dissertation work is the result of an ethnographic study undertaken with the residents of the Community Maloca, Vargas located in the neighborhood adjacent to the commercial center in Aracaju - SE. Since February 2007 the group is certified by FCP - Palmares Cultural Foundation as a lasting community, while it is part of a special gift for being an urban center, varying from the majority of that remaining Maroons in their contexts, outcrops and specific land rural. It focuses on the work process of territorial formation of the hut, and the arrival of their first actors, contextualizing the process of legitimation refers to the territory they live, as well as the various narratives that (re) construct the time he lived, the relations kinship, conflict, the process of self-affirmation as runaways and the relationship of belonging with their living space / living contained in the imaginary city of Aracaju. Attempts are made to the opportunity to understand the meanings that affirm their ethnicity, parallel group for the pursuit of effective policies and guarantee of constitutional rights in the urban context.

Habitus e territorialidade na composição da dinâmica imobiliária em Natal/RN

Many have sought to understand the spatial processes, which originate from land development and real estate dynamics, seeking also to build new categories of analysis to put some light on the less evident aspects of this process. The discussion about production of space has been adopted in this study, but has proved insufficient to explain this complex urban reality. Here, it is analysed the ways that, in Natal, the market fosters the material basis for capital accumulation. The research had as methodological basis, the analysis of discourse, having full interviews with institutional agents as background. It aimed at understanding the complex, material configuration in urban space. It thus investigates the theory of practices of existing (private and public) agents towards the real estate market, using several concepts, like production of space (Lefèbvre and Harvey); habitus (Bourdieu); spatial fix (Harvey); and territoriality (Haesbaert). Evidence shows that there has been a process of ‗naturalization of certain practices in the market that has had implications for the production of an urban space that is both segmented and segregated, giving rise also to complex material configurations, including different forms of heterotopies (Foucault). These spaces result from capital s own creative dynamics and of the reach for social realization for different groups of people making a living under different economic conditions of income.

Aprendendo a pertencer: uma leitura da trezena de Santo Antônio em Pradoso enquanto territorialidade humana

The Novena of St. Anthony in Pradoso, is an annual celebration that takes place between June 1 and June 13. Since its preparation to the conclusion of the celebration are employed traditional knowledges and techniques, which are shared by the community. Such knowledges, built over generations, associated with popular religion, form it into the educational processes that build, through orality, practices and experiences of everyday life, the sense of belonging. An analysis of scenes, knowledges and subjects involved in the celebration, shows the form and content of practices capable of building symbolic territories of belonging. Thus, the Novena of St. Anthony in Pradoso, while an human territoriality, is designed as a locus of learning of belonging, reaffirming community values such as solidarity, service, brotherhood, integration, among others. While empirical reference for an analysis of the importance of belonging, the Novena of St. Anthony in Pradoso, offers subsidies for the production of knowledge, focused on understanding the need for a reconnection of technical and humanistic knowledges

Comportamento social e territorialidade alimentar na garça-azul, Egretta caerulea (L) = Feeding territoriality in the little blue heron, Egretta caerulea (L)

The use of habitat is an important part of a species biology. One resource of great importance for the survivor and reproduction of an individual is the food resource. Thus, the social interactions an animal has during the feeding activities are of extremely importance within its behavioral aspects, which represents the part of an organism trough which it interacts with the environment, adapting to changes and variations. Herons are known to form feeding aggregations of even more than thousands of individuals, in which social components of foraging have been identified and studied for several species. More profound studies of these aspects are yet to poor for the Little Blue Heron, Egretta caerulea. Therefore, the aim of this study was to describe the social behavior (display postures, vocalizations and co-specific interactions) and the territoriality of the specie during the feeding period in an area of mud bank in the estuarine system of Cananéia, south coast of São Paulo state, Brazil. The defense of a fixed and exclusive area, closest to the mangrove, trough expulsion was observed; some thing that have not yet been registered with concrete data for the specie. Higher capture and success rates, and lower investment rates (steps/min and stabs/min) were registered for individuals foraging in areas corresponding to the defended territory. This could be one of possible reasons for the establishment of territories in the area. Four display postures were registered for the specie, two of then new in the literature, which are used in the interactions between individuals; one vocalization, that apparently is important in the social context of foraging for the specie and, possibly, has a function of advertising and proclaiming the dominance position of the territorial individual within the group. A territorial individual uses three behaviors, of the ones described: expulsion, vocalization and encounter (agonistic encounter between individuals, without physical aggression). Of these, the expulsion is apparently used in the actual defense, actively; while the other two behaviors are used in a more passive way, in the maintenance of the dominance position of the individual, helping it in the defense of its territory in a less direct manner. Therefore, with the results presented in here, new components of the social utilization of the feeding resource for the Little Blue Heron were identified, incorporating aspects of the territorial behavior for a future understanding of its possible adaptive significance. And it also reinforces the importance of the social interactions of herons foraging in great aggregations, in areas ecologically important

Territorialidade e pesca: atualidades e tradições no uso dos recursos pesqueiros na comunidade litorânea da praia da Pipa Rio Grande do Norte

The need for sustainability in the exploitation of natural resources in coastal areas has been out in recent years, as well as the social and cultural sustainability of traditional communities in these regions. Coastal and estuarine wild areas are influenced directly or indirectly by a set of human activities such as artisanal fishing. Therefore, there is a demand for an integrated design of these areas and according to the landing values, a pattern of unsustainable development of national marine fishing activity. The study was conducted in the coastal community of Praia da Pipa, Tibau do Sul municipality, RN, between june 2009 and june 2010 and aimed to characterize the fishery performed, its socio-economic strategies and fishing areas, as well as to identify ichthyofauna, to assess the sustainability of the major resources and to identify cultural traits related to artisanal fisheries, their problems and prospects; linking tradition and the present fishing activity carried out in the community. For this study, a total of 67 structured interviews were collected, including qualitative and quantitative data. A total of 133 fish landings and direct observations were performed. Informants were identified according to one of the following categories: fishermen, vessel masters and members of the local population with offspring. Applications SPSS 10.0, Paint.Ink and Microsoft Office Excel 2007 were used for tabulation and analysis of results. Local fishermen are, on average, 25 years fishing, have 40 years old and the average monthly income is up to 03 minimum wages. The local fleet consists of 20 vessels, that uses different line sizes and types of networks, operating in 21 fishing grounds and showing a reduction in the vessel numbers by 66% in the last decade. We recorded 76 species of fish, captured by the local fleet and the top 5 were quantitatively analyzed serra spanish mackarel (Scomberomorus brasiliensis), little tunny (Euthynnus alleteratus), yellowtail snapper (Ocyurus chrysurus), red snapper (Lutjanus analis) and common snook (Centropomus undecimalis), accounting for 46,5% of production in the period. The capture of these species was composed mostly of adults. Data analysis showed a significant decrease of the local fishing activity over the last decade due to the weakness displayed by the political-social category, the devaluation of local knowledge and the emergence of new sources of income through increased tourism. The characteristics of the fishing community suggest it to pass through significant changes as the appreciation of their cultural and traditional aspects. We identified a tendency to sustainability of main species caught, suggesting that public policies to be adopted locally comply with the current characteristics of fishing undertaken in the community and knowledge of fishermen related to the environment, allowing environmental, as well as social and cultural sustainability of the community involved.

Síndrome de Berardinelli :territorialidade e imaginário

The Syndrome of Berardinelli or Congenital Generalized Lipodystrophy, known popularly in Seridó as "The Magicians", it is considered in the world as a rare syndrome and of few studies. In Rio Grande do Norte, specifically, in the Area of Seridó, an important incidence of bearers was verified. Face to present subject, this work describes in beginning the origin and evolution of the referred syndrome, standing out the genealogy of the families of the bearers in the temporary cutting that dates of the beginning of the century XIX to the current days and, later, it s has as purpose to justify the territorialities and the imaginary of the Syndrome and Berardinelli starting from the lived experiences, of the conidian and of the social practices. That implicates to verify as those people they fragmented certain places, like them they noticed her and they were noticed by the society. The methodological approach for the accomplishment of that research is of qualitative order in a perspective phenomenological, ethnography and historical, once the analysis is not just ruled in the product, but it takes in consideration the life history. The analysis presents the way as the depositions they make sense in the context of the study of the genealogy, of the perception imagery of the society before them and the image constituted by them, of himself and of the other. The data, still, demonstrate that the a lot of people's existence with to Syndrome in Seridó happens due to the consanguinities among the families

Partilha de néctar de Eucalyptus spp., territorialidade e hierarquia de dominância em beija-flores (Aves: Trochilidae) no sudeste do Brasil

Territorial behavior in hummingbirds minimizes competition through aggressive interactions, resulting in a dominance hierarchy among species and individuals. Interactions among seven hummingbird species visiting flowering eucalyptus in the Floresta Estadual near Rio Claro, São Paulo, in southeastern Brazil, were studied. Dominance was determined by weight and size with the largest species being the most dominant. Time spent in defense and the number of aggressive interactions were greater than recorded in literature, perhaps due to the relatively greater density of hummingbirds in the study area. Daily activity patterns differed among dominant and subordinate species, but were not correlated with either the quantity of available nectar or with nectar sugar concentration.
