STRUCTURE OF THE SHRUB-ARBOREAL COMPONENT OF AN ATLANTIC FOREST FRAGMENT ON A HILLOCK IN THE CENTRAL LOWLAND OF RIO DE JANEIRO, BRAZIL

The present study describes and evaluates the horizontal and vertical structures of a lowland forest fragment on a hillock in the municipality of Silva Jardim, Rio de Janeiro State, Brazil (22 degrees 31`56 `` S and 42 degrees 20`46 `` W). Twenty plots (10x2m) totaling 0.5ha were laid out following the slope grade using DBH >= 5cm as the inclusion criterion. A total of 734 individuals were encountered, yielding a total density of 1468 ind./ha and a total basal area of 10783m(2). The richness values (129 species/41 families), Shannon-Wiener diversity (4.22) and equitability (0.87) indices indicated an accentuated floristic heterogeneity and low ecological dominance. Lauraceae, Myrtaceae, Fabaceae and Euphorbiaceae showed the greatest species richness, corroborating other studies that indicated these species as the most representative of Atlantic Forest areas in southeastern Brazil. The species with the greatest importance values (VI) were Aparisthmium cordatum, Guapira opposita, Lacistema pubescens, Xylopia sericea, Tapirira guianensis and Piptocarpha macropoda. The high diversity observed was influenced by earlier anthropogenic actions and by the current successional stage. The forest fragment studied demonstrated closer floristic similarity to areas inventoried in a close-by biological reserve than to fragments dispersed throughout the coastal plain. Similarities in soil type, degree of soil saturation and use-history of forest resources all support these relationships. The fragmented physiognomy of the central lowland in this region and the use-history of the landscape make these small remnant forest areas important in terms of establishing strategies for landscape restoration and species conservation.

Escolhas estratégicas e guerra fiscal: competição ou cooperação no caso do Estado do Rio de Janeiro

Este estudo tem por objetivo analisar as tendências atuais para a cooperação ou competição entre os estados brasileiros, nos jogos predatórios para atração de investimentos privados. Investigamos o processo de construção de agendas, relacionado às opções do Estado, no momento em que se debate a reforma tributária e o fim da "guerra fiscal". A pesquisa apresenta as razões históricas da questão e enfoca as condições estratégicas nas quais o Governo do Estado do Rio de Janeiro pode se inserir nessa agenda política. Os resultados revelam que, sem a superação de um conjunto de fragilidades na estrutura federativa e no sistema tributário nacional, mesmo com fortes lideranças políticas e mecanismos regulatórios, o jogo competitivo entre os estados não alcançará, em curto ou médio prazo, um padrão salutar.

A justiça distributiva como critério fundamental nas políticas públicas: o caso dos jogos panamericanos na cidade do Rio de Janeiro

This dissertation is a project of evaluation of the proposals of the Panamerican Games of 2007, that they will be carried through in the city of Rio De Janeiro. Great events present the possibility of improvement of the urban space and economic development, amongst other chances seen by politics and urban planners well. For this work we search to argue the city as field of specific study, understanding it in the current world-wide scene of globalization and computerization, the relations politics, economic and social existing interns. We search in material literature to study and to evaluate what it would be a ¿good city¿ and studies that had understood the development of the urban space. We also look for to understand the city of Rio de Janeiro as a singular urban space, since the origin of the city as a urban space, passing for the proposals gifts of modification of the carioca space. We dedicate part of the work, inside of the chapter where we understand the city of Rio de Janeiro, the presentation of the project of the Panamerican of 2007, comparing it with great previous events. The vision of technique and politics during the interviews was essential for the best understanding of the proposals of the Games. Finally we evaluate the proposals of modification of the Pan2007 for the city of Rio de Janeiro with the methodology of Kevin Lynch to evaluate the good form of the city" in communion with the proposal of distributive justice of Rawls. The result of this evaluation was that the current proposals of modification of the city for the Pan2007 will be able to generate resulted not deliberate for a considerable parcel of the population and to modify the economic relations harmfully, social and politics inside of the territory of the city. For such we consider measured compensatory satisfactory that they can reach the objectives of an equal citizenship and an equitable equality of chances, starting for the offering of the social minimums of just form.

Organizações culturais e (re)configuração do espaço: o caso do Istituto Europeo di Design, na cidade do Rio de Janeiro

O presente estudo tem como objetivo investigar de que maneira a possibilidade de instalação do Istituto Europeo di Design (IED) no bairro da Urca, na cidade do Rio de Janeiro, interfere na (re)configuração do espaço. Para o estudo desse processo adotou-se o conceito de espaço definido por Milton Santos, que o caracteriza como um conjunto indissociável de sistemas de objetos e ações, considerando necessária sua análise numa perspectiva histórica. Para ampliação das considerações sobre poder, identificação e caracterização dos atores sociais e das relações entre eles estabelecidas foram utilizados conceitos propostos por Carlos Matus para a análise da realidade social. A pesquisa de campo, de natureza qualitativa, coletou dados secundários a partir de notícias sobre o processo de revitalização do antigo Cassino da Urca e instalação do Istituto Europeo di Design no local, publicadas em jornais e revistas impressos, jornais on line e blogs, assim como dados primários, a partir de observação não estruturada das instalações ao redor do prédio do antigo Cassino da Urca, participação em reuniões da associação de bairro e entrevistas semi-estruturadas com representantes de organizações envolvidas no processo. Para o tratamento dos dados coletados, realizou-se análise argumentativa e interpretativa a partir da teoria utilizada. Com base nas notícias e documentos consultados, foi definido o período de análise, desde a cessão do prédio do antigo Cassino da Urca ao IED, em agosto de 2006, até o anúncio de parceria com outra organização, pelo instituto, em maio de 2012. O estudo permitiu identificar que a instalação do IED na Urca interferiu na configuração do espaço, principalmente no que se refere à formação e à atuação da associação de moradores do bairro, à instalação de novos empreendimentos comerciais no entorno do prédio já restaurado e, por consequência, na paisagem do bairro. Destaca-se também que a instalação do IED gerou mudanças que extrapolam os limites territoriais do bairro. Com base nos dados analisados, destaca-se que a relação de cooperação entre a Prefeitura Municipal do Rio de Janeiro e o IED foi estabelecida em torno da valorização por parte da Prefeitura do domínio de uma capacidade técnica pelo IED, nas áreas de atuação da organização, que são o ensino, pesquisa e consultoria nas áreas de arquitetura, design, moda e comunicação, o que reforça o argumento da valorização atual de organizações culturais no processo de (re)configuração do espaço urbano, quanto aos aspectos econômicos, simbólicos e sociais.

Factors associated to Theileria equi in equids of two microregions from Rio de Janeiro, Brazil

Amostras de soro de 714 equídeos das microrregiões de Itaguaí e Serrana, Rio de Janeiro, Brasil, foram submetidas ao teste de imunofluorescência indireta (título 1:80) para Theileria equi. A prevalência entre as microrregiões e os fatores associados à soropositividade foram avaliados e a razão de prevalência (RP) calculada. A prevalência geral para T. equi foi de 81,09% (n = 579), com maior prevalência (p < 0,05) para microrregião de Itaguaí (85,43%), quando comparado a Serrana (76,92%). A região, altitude, nível da propriedade e origem dos equídeos foram associados (p < 0,05) com a soropositividade para T. equi. Equídeos criados na microrregião de Itaguaí (RP = 1,11; p = 0,003) e em altitudes abaixo de 500 m (RP = 1.10; p = 0,014) apresentaram maior chance de se tornarem soropositivos para T. equi. Além disso, quando são criados em propriedades de nível ruim (RP = 1,13; p = 0,018) e nascidos na propriedade (RP = 1,10; p = 0,008) apresentaram mais chance de terem contato com T. equi. As principais espécies de carrapatos encontradas parasitando os equídeos foram Amblyomma cajennense e Dermacentor (Anocentor) nitens. As microrregiões estudadas são endêmicas para theileriose equina e de estabilidade enzoótica para T. equi. Apenas os fatores relacionados à área de coleta das amostras de soro influenciaram a soropositividade dos equídeos para T. equi naquela região.

How do cold water biota arrive in a tropical bay near Rio de Janeiro, Brazil?

Previous ecological studies on foraminifera and ostracoda from the tropical Sepetiba Bay, located in the southern part of the State of Rio de Janeiro, Brazil, have noted the presence in this area of some cool water taxons typical of the Argentine continental platform. These studies have proposed that parcels of these temperate waters with their associated biological indicators are advected northward along the platform, penetrating into some tropical entrances of the southeast coast of Brazil. In the present study, ecological data (foraminifera, ostracoda and microbivalves), are used together with information obtained by satellite tracked drifting buoys and digital thermal imagery obtained from NOAA satellites to indicate the path taken by these high latitude species along the southern Brazilian coast to arrive in the Sepetiba Bay, near the city of Rio de Janeiro. Our general conclusion is that biotic elements native to the colder, less saline marine waters seen to the south of Brazil have been and are being advected northward along the inner part of the continental platform to about 22 degrees S. Water parcels containing this biota may, in a sporadic fashion, enter into the tropical Sepetiba Bay. The passage of meteorological fronts through the region is considered to be an important if not the principal mechanism for the sporadic entry of the cool water into the Southern Coastal Entrance of the State of Rio de Janeiro.

Epidemiologic Evaluation of Mandibular Fractures in the Rio de Janeiro High-Complexity Hospital

The aim of this study was to gather data on trauma etiology and mandibular fracture localization in patients who presented at the General Hospital of Nova Iguacu, Rio de Janeiro, Brazil. From March 2007 to December 2008, 95 patients with mandibular fracture were registered in a medical form, at the Bucomax-illofacial Surgery Department of the General Hospital of Nova Iguacu, Rio de Janeiro, Brazil. Concerning mandibular fracture etiology, 21.05% were caused by motorcycle accidents, followed by interpersonal violence without use of weapons (punches, kicks, bumps with the head, blows with the elbow, etc) (16.84%) and interpersonal violence with firearm (14.73%). It was found that 52.63% of the patients had a single fracture line. The most affected fracture area was the parasymphysis (26.02%), followed by the condyle (22.60%) and mandibular angle (18.49%). Concerning the injury area, 24.21% were directed to the mandibular symphysis, 22.17% of the patients did not remember the injury area, and 18.94% had multiple injuries. When the injury was directed to the symphysis, the result was more condyle fractures (11.64%), and injuries at the mandibular angle resulted in fractures at the angle itself (8.90%). The most common fracture cause was traffic accidents, mainly motorcycle accidents, and the most affected areas were the parasymphysis and the condyle. The mandible isolated fractures occurred in half of the cases. Motorcycle accidents resulted in more fractures in the parasymphysis area, and when the symphysis area is affected by injuries, the result is a higher percentage in condyle fractures.

The reproductive biology of Diplodus argenteus (Sparidae) in the coastal upwelling system of Cabo Frio, Rio de Janeiro, Brazil

The reproductive biology of the seabream Diplodus argenteus, a dominant coastal fishery species, was investigated over two consecutive seasons (2001-2002) at Cabo Frio, Brazil, a low-latitude upwelling system. The sex ratio was dominated by females (1.4:1.0) and the length-at-50% sexual maturity (females) was 203mm total length. Females were multiple spawners and the reproductive pattern appeared to be digynous protandrous hermaphroditism. Monthly variations in gonadosomatic index and proportion of ripe females indicated that reproductive activity occurred from late winter to summer (August-February), following coastal upwelling.

Population structure of the lancelet Branchiostoma caribaeum (Cephalochordata: Branchiostomidae) in the Baia de Guanabara, Rio de Janeiro, southeastern Brazil

Population structure of the lancelet Branchiostoma caribaeum Sandevall, 1853 was studied in four surveys, corresponding to austral seasons, in a tropical bay, southeast of Brazil. Abundance was higher in the spring and was positively correlated to coarse sediments, limiting its occurrence to some sectors of the sampling area. Body length and biomass differed seasonally but not between sexes. Sexually mature individuals occurred in all seasons, suggesting continuous breeding that is typical of tropical species. Variation in the frequency of small specimens indicates temporal differences in the intensity of breeding. The body length of recruits differed from other population of lancelets and the small length which B. caribaeum attained sexual maturity in Guanabara Bay may be related to local environmental stress or the great availability of food.

LITTER DEVOLUTION AND DECOMPOSITION IN A PERIODICALLY FLOODED FOREST IN RESTINGA DA MARAMBAIA, RIO DE JANEIRO

Restinga (sandbank) areas are fragile environments, which have been subjected to anthropogenic pressures since the country colonization. So that mitigate actions can be taken, it must be developed studies to better understand the ecological processes in these environments. Thus, this study aims to quantify litter and nutrients devolution and litter decomposition in a periodically flooded forest in 'Restinga da Marambaia', Rio de Janeiro. In the study area 10 conic collectors and 30 litter bags were installed. The annual litter devolution was 7.64 Mg.ha(-1), and September was the highest contribution month. Nitrogen was the element returned to the soil to a higher amount (71.9 kg ha(-1) yr(-1)), followed by potassium (41.1 kg ha(-1) yr(-1)). Litter decomposition rate 0.0015 g g(-1) day(-1) and the half-life were 462 days. Potassium was the element that showed the highest losses in comparison to the others. Cellulose appeared as a major participant in the structure of leaf litter, followed by lignin, the latter being associated with the leathery texture of the leaves in this formation.
