O presente artigo trata da ação cultural do griô Zé Santana em Ilha Grande-PI, no Delta do Rio Parnaíba. O objetivo é analisar as contribuições da ação cultural de Zé Santana na comunidade ribeirinha de Ilha Grande-PI. Especificamente, almejamos: caracterizar a ação cultural de Zé Santana, enfatizando sua constituição como um educador cultural; relacionar o fazer desse mestre griô com uma possível prática educativa; mostrar a relevância da produção artístico-literária do referido mestre popular para a educação, história e memória cultural do povo ilhagrandense. Trata-se de uma pesquisa qualitativa, desenvolvida à luz da metodologia de Análise de Conteúdo, tendo como técnica a entrevista semiestruturada aplicada com cinco moradores da referida região. A base teórica se fundamenta em Bardin (2016), Brandão (2007), Santos (1994), Werneck (2003), dentre outros. O estudo mostrou que as ações dentro da comunidade fizeram de Zé Santana uma espécie de educador cultural, pois seu fazer possibilitou diferentes formas de aprendizado e de construção de conhecimentos sobre a vida e a cultura no espaço da cidade em questão.

Panstrongylus geniculatus (Latreille, 1811) is the most widely distributed species in Brazil. This study presents the first report of this species collected inside a building in the “Centro de Estudos Ambientais e Desenvolvimento Sustentável”, at the Vila Dois Rios, Ilha Grande, Rio de Janeiro, Brazil. The new record is important to understand the risk of Chagas disease transmission, mainly because this species is commonly found infected with Trypanosoma cruzi (Chagas, 1909).

Few studies that apply the theory of island biogeography have considered the functional and phylogenetic dimensions of diversity. However, the joint use of the three diversity dimensions, i.e. taxonomic, functional and phylogenetic, can help us to gain a better understanding of the mechanisms underlying ecological and evolutionary processes. Here, we compare phyllostomid bat assemblages between five land-bridge islands off the south-east coast of Brazil and compare these islands with three sites on the mainland. For this, we have estimated the three dimensions of α- and β-diversity, nestedness and community indexes based on mean trait values for the islands and the mainland. The mainland showed higher species richness and taxonomic, functional and phylogenetic diversity. In addition, only species richness and phylogenetic diversity were positively related to island area. Taxonomically and functionally, the poorest assemblages (minor islands) were subgroups of the richer assemblages (mainland and larger islands). Taken together, our results show that bat assemblages of smaller islands tend to be more sensitive to changes in species richness than those of larger islands, with the larger islands working as a 'source' of species for small islands. These results demonstrate the high conservation value of the larger islands, which has direct consequences for local population dynamics of phyllostomid bats. [ABSTRACT FROM AUTHOR]

Differences resulting from the passage of migrating dunes in coastal restinga vegetation in Ilha Grande, Piauí, Brazil were quantified, especially differential survival of tree species (wild Anacardium occidentale, cajuí; Byrsonima crassifolia, muricí) and successional floristic reestablishment. A phytosociological study totalling 108 quadrats (1.08 ha) and satellite images of the area from the past 16 years were used to examine the vegetation of the upwind tracks of two mobile dunes. Quadrats were arranged in four transects along the central and marginal residual ridges of each dune. Most species recorded were herbaceous. Satellite images suggest that plants along the central dune track are buried for approximately 14 years. Some evidence for progressive re‐establishment of woody species was found in the central dune track areas, but not in the marginal areas. No successional patterns were observed in the herbs and subshrubs. Most trees occur along the marginal (longitudinal) residual ridges. Anacardium occidentale and Byrsonima crassifolia predominated among tree species. Anacardium occidentale predominated in abundance, cover, frequency and basal area and survives partial burial when located at the dune track margins. The passage of migratory dunes is important for long term maintenance of the economically important cajuí and muricí populations of Ilha Grande. [ABSTRACT FROM AUTHOR]

In order to analyze temporal variability on the gamma dose absorbed in the air in beaches in Ilha Grande, Brazil, in 2011–2012 new measurements were made in four of ten beaches analyzed previously in 2001. The measurements were performed directly with a proportional detector. The values varied between 47 ± 5 (Lopes Mendes) and 97 ± 11 nGyh−1 (Caxadaço) Praia Preta. The average annual effective dose was 0.08 ± 0.02 mSv year−1 , in line with the world average of effective external doses, 0.07 mSv year−1 according to UNSCEAR. No statistically significant change was observed after 10 years. [ABSTRACT FROM AUTHOR]

As razões que levam os homens à contemplação da natureza e à constante busca de uma relação harmoniosa com o meio podem ser encontradas a partir da Antigüidade, através de uma Geografia mais imaginária que real. É nesse contexto que vemos o nascimento das idéias a respeito do isolamento que a ilha oferece, representando um refúgio, um ambiente de harmonia e felicidade, enfim, um paraíso a ser preservado. E é nessa linha de pensamento que apresentamos aqui uma tentativa de entender a preocupação em transformar a Ilha Grande, situada no Rio de Janeiro, em nosso santuário ecológico".

We evaluated the structural responses of marine sponge assemblages to different substrates as well as their positioning around Ilha Grande, a local hotspot of marine biodiversity sheltered in a bay area off Southeast Brazil. Sampling sites were distributed between sides of the island facing the continent (North) and ocean (South) across two depth-dependent substrates. As proved by ordination and permutation analyses, these two factors accounted for nearly half the variation observed among assemblages, either with species abundance or coverage area data. Out of 46 OTUs surveyed (~ 3000 individuals), Tedania (Tedania) ignis, Scopalina ruetzleri, and Iotrochota arenosa dominated the community, even though most of the dissimilarity detected among assemblages relied on 20% of the OTUs. The northern side was proved as more diverse, and the south-facing side held more unspecific, putatively new OTUs. Assemblages dwelling on rocky-to-sandy interface bottoms were meager in species number, although they mainly included Dragmacidon reticulatum and the endemic Brazilian sponge Polymastia janeirensis. By highlighting structuring factors operating on Ilha Grande's sponge assemblage, we hope to support future monitoring surveys on an environment increasingly impacted by human activities over the years.

ABSTRACTPsychotria is the largest Rubiaceae genus and one of the most abundant in the Atlantic Rainforest of Rio de Janeiro State. The present work aims to characterize and compare the wood of nine of these species. ThePsychotria wood were characterized by: slightly distinct growth rings; diffuse porosity; solitary vessels or on radial multiples of 2-6 or clusters of 3-5 vessel elements, with terminal and lateral simple perforation plates and vestured and alternate intervessel and vessel-ray pits; septate fiber-tracheids; and rare axial parenchyma. Although, the wood anatomy of thePsychotria may be considered homogeneous, the statistical analyses, based on qualitative and quantitative features, allowed the segregation of the species and indicated the importance of habit (arboreous or shrubby) on the wood anatomy of the species. It is worth mentioning that the sampling was realized in only one studied site (Ilha Grande), which contributed to the conclusion that the wood characteristics are more related to the specificities of each studied taxon than to with environmental variations.

Most work with frogs has provided high relevance of information focusing primarily on adults, which is mainly due to the difficulty of identifying the larval stage of these organisms. Ilha Grande, the third largest island at the Brazilian coast, is one of the most important remnants of the Atlantic Rainforest Biome in Brazil. This study aimed to characterize the morphology of the tadpoles of 11 frog species that occur in oceanic face (southwards) of the Ilha Grande, Southeastern Brazil. Using these characters, we provide a key for the identification of these tadpoles. [ABSTRACT FROM AUTHOR]

Ivierhipidius Barclay, 2015 is a genus of little modified ripiphorids. Ivierhipidius monneorum Barclay, 2015 was described based on five specimens from the Corcovado, the famous site of the Christ Redeemer statue in Rio de Janeiro, southern Brazil. To this date, the species is published only from the type location and type specimens. This paper provides a new distributional record for the species (in Ilha Grande, Angra dos Reis, Rio de Janeiro State), along with a map of its distribution. [ABSTRACT FROM AUTHOR]

Este trabalho apresenta a análise limnológica e o mapa de uso e cobertura da terra da bacia hidrográfica do córrego da Ilha Grande, localizado em Presidente Bernardes-SP no Pontal do Paranapanema. O estudo limnológico ocorreu em cinco seções amostrais analisando-se as variáveis limnológicas oxigênio dissolvido, pH, condutividade elétrica, temperatura da água, amônia e turbidez através da multisonda paramétrica da marca Hanna modelo HI 9829 e as frações de fósforo dissolvido, reativo solúvel e total segundo Mackereth, Heron e Talling (1978). O mapa foi elaborado no software ArcGis 10.2 utilizando ortofotos da Emplasa obtidas em 2011, a partir dele verificou-se como uso predominante da terra as pastagens, com a existência de áreas sem vegetação ciliar, causando problemas de erosão. Analisando os dados limnológicos observou-se que grande parte dos parâmetros estava de acordo com a Resolução Conama 357/05 e os parâmetros não estabelecidos pela resolução não apresentaram grandes variações na maior parte das seções.

Based on the study of Ilha Grande's prisons in the first half of the twentieth century, this paper investigates the construction of a punitive culture that criminalized social groups in poor living conditions. The term "vagabundo" [vagrant], which justified the arrest and mistreatment of thousands of individuals in the post-abolitionist period, was present in laws and penal codes, in legislators' thought, and in so-called scientific texts. The meeting between political leaders opposed to Vargas' government and the so-called vagrants indicated differential treatments and the naturalization of the concept. Interviews with prison guards of the Colônia Agrícola do Distrito Federal, built in 1942, indicate how these classifications were operating within the prison system, and how they were deployed.

Apresenta a Ilha Grande, distrito de Angra dos Reis, sua inserção na economia mercantil de subsistência e a memória da escravidão que se encontra no Registro Civil de Angra dos Reis. O Almanaque Laemmert informa que esse distrito possuiu o maior número de escravos do município, a partir da década de 1870. Seus proprietários, em sua maioria, eram senhores de poucos escravos, e as propriedades majoritariamente pequenas. O Registro Civil de Angra dos Reis não se esqueceu da escravidão depois de maio de 1888. Várias comunicações de nascimento e falecimento qualificaram as pessoas, informando sua condição anterior de escravo. Mesmo no século XX, os escrivães não deixaram de qualificar vários cidadãos republicanos como ex-escravos.The article introduces Ilha Grande, a district in the municipality of Angra dos Reis, and describes its role within the subsistence market economy and the memory of slavery as found in the Angra dos Reis Civil Records. According to the Almanaque Laemmert, this district had the largest number of slaves in the municipality as of the 1870s. Most owners had few slaves, and the majority of landholdings were small. The Angra dos Reis Civil Records did not forget slavery after May 1888. A number of birth and death notifications describe the persons in question as former slaves. Even in the twentieth century, clerks continued to describe various republican citizens as ex-slaves.

Este trabalho apresenta o levantamento florístico das espécies nativas de Moraceae ocorrentes na Ilha Grande, município de Angra dos Reis, Estado do Rio de Janeiro, Brasil. Com base na análise de coleções científicas, revisão da literatura e excursões a campo, foram registradas 11 espécies nativas: Brosimum guianense, Dorstenia arifolia, Ficus adhatodifolia, F. arpazusa, F. cyclophylla, F. gomelleira, F. nevesiae, F. organensis, F. pulchella, Sorocea hilarii, S. guilleminiana. Apresentamos, também, a chave de identificação para os táxons, descrições, ilustrações, informações sobre a distribuição geográfica e comentários sobre as espécies. This work presents a floristic survey of native species of Moraceae occurring in Ilha Grande, municipality of Angra dos Reis, Rio de Janeiro state, Brazil. It was based on analysis of herbarium collections, literature review and the field excursions, resulting in 11 native species: Brosimum guianense, Dorstenia arifolia, Ficus adhatodifolia, F. arpazusa, F. cyclophylla, F. gomelleira, F. nevesiae, F. organensis, F. pulchella, Sorocea hilarii, S. guilleminiana. We also present the identification key to the taxa, descriptions, illustrations, information about geographic distribution and comments on these species that enriched the results.

O trabalho trata da morfologia polínica e de descrições taxonômicas de 12 espécies de Asteraceae correspondentes em 12 diferentes gêneros, distribuídos em nove tribos. Todas as espécies estudadas são utilizadas como medicamentos pelos moradores da Vila Dois Rios, Ilha Grande, Angra dos Reis, Rio de Janeiro. Neste estudo objetivou-se caracterizar os tipos polínicos das espécies usadas por esta comunidade e fornecer chaves diagnósticas de caracteres macromorfológicos e micromorfológicos que auxiliem a identificação das mesmas. A identificação taxonômica e palinológica correta é pré-requisito para estudos que validem a eficácia e segurança terapêutica dessas espécies. Deve-se considerar, ainda, que a utilização desses conhecimentos é importante para a comunidade, como por exemplo, na melissopalinologia. Os grãos de pólen foram acetolisados, medidos, descritos e ilustrados sob microscopia de luz. Para observar detalhes da superfície e abertura, grãos de pólen não acetolisados foram analisados em microscópio eletrônico de varredura. Foram estudadas as características dos grãos de pólen como forma, tamanho, constituição da sexina e abertura. Os resultados mostraram que a morfologia polínica é bem definida entre as espécies estudadas, podendo ser usada para sua identificação e sustenta o caráter euripalinológico de Asteraceae.This study is a palynologycal characterization and taxonomic description of 12 species within 12 genera, distributed in nine tribes from Asteracaeae. All studied species are used as medicines by people from Vila Dois Rios and they occur in Ilha Grande. This work aimed to characterize the pollen grains of medicinal species of Asteraceae from Vila Dois Rios and provide diagnostic keys based on macromorphological and pollen characters to help their identification, since the correct taxonomic and palynological recognition of these species is necessary for further studies on therapeutic effectiveness and safety. It must be considered that these acknowledgments have economic importance for the community, as melissopalynology practices are taking place in Vila Dois Rios. The pollen grains were acetolysed, measured decribed and illustrated under light microscope. To observe details of aperture and surface, non acetolysed pollen grains were analysed under scanning electronic microscopy. Characteristics like shape, size, sexine and aperture constitution were studied. The results show that the palynological characterization of these species is a valuable tool to differ them from each other and sustains that Asteraceae is euripolinic.

We studied some parameters of the parasitism by the mite Hannemania sp. on the endemic frog Hylodes phyllodes in the Atlantic Forest of Ilha Grande (Rio de Janeiro State, Brazil). Prevalence, mean abundance, mean intensity and total intensity of infestation, body regions infected, and host sexual differences in parasitism rate of the larvae of Hannemania sp. on individuals of H. phyllodes were assessed. Prevalence was 86.5% (N = 37; total of 1,745 larvae of Hannemania sp) for male hosts and 91.7% (N =12; total of 330 larvae) for female hosts, with no significant difference between the sexes. Overall prevalence of Hannemania sp. on H. phyllodes was 87.7%. Mean intensity of infestation in males (54.5 ± 42.5; range 1-173 larvae) was higher than in females (29.9 ± 47.6; range 1-166). We conclude that the rates of intensity, abundance, and prevalence of Hannemania larvae parasitizing Hylodes phyllodes at Ilha Grande were considerably high, suggesting that this species of anuran constitutes a relevant host for this mite species to complete its lifecycle in the area. Differences between males and females in infestation rates probably reflect their differential use of space in the forest.

We analyzed the diet and microhabitat use for two Hylodinae anurans (Cycloramphidae), Hylodes phyllodes Heyer & Cocroft, 1986 and Crossodactylus gaudichaudii Duméril & Bibron, 1841, living in sympatry at an Atlantic Rainforest area of Ilha Grande, in southeastern Brazil. The two species live syntopically at some rocky streams. The two species differed strongly in microhabitat use. Hylodes phyllodes occurred mainly on rocks, whereas C. gaudichaudii was observed mostly on the water. Regarding diet, coleopterans, hymenopterans (ants), and larvae were the most important prey item consumed by both species. Data suggest that microhabitat use appears to be an important parameter differentiating these frogs with respect to general resource utilization.Nós analisamos a dieta e o uso do microhabitat em duas espécies de anuros da subfamília Hylodinae (Cycloramphidae), Hylodes phyllodes Heyer & Cocroft, 1986 e Crossodactylus gaudichaudii Duméril & Bibron, 1841, que vivem em simpatria em uma área de Mata Atlântica na Ilha Grande, na região sudeste do Brasil. As duas espécies vivem sintopicamente em alguns riachos pedregosos. As duas espécies diferiram fortemente no uso do microhabitat. Hylodes phyllodes ocorreu principalmente sobre pedras, enquanto C. gaudichaudii foi observado na maioria das vezes dentro d'água. Com relação à dieta, coleópteros, himenópteros (formigas), e larvas foram as presas mais consumidas por ambas as espécies. Os dados sugerem que o uso do microhabitat parece ser um importante parâmetro diferenciando esses anuros com respeito a utilização de recursos.

The Ilha Grande is situated at the intersection of the parallels 23°05' and 23°14' degrees Southlatitude with the meridians 44°05' and 44°23' West longitude, in Angra dos Reis county, at the Riode Janeiro state Southern coast. It has approximately 193Km² and has two districts, Araçatiba,situated at the western portion whose main villa of residents is Provetá, and Abraão, situated atthe East portion where detaches as the main village the Vila de Abraão. The Vila de Abraão isconsidered the “capital” of the Ilha Grande, where arrive and alter on a daily basis, inhabitants,visitors, public managers, researchers and environmental defenders. The present article considersenvironmental impacts in the Vila de Abraão as important vectors in the construction of managementprocess and territorial planning, mainly after the Island’s change of function - from federal prison(Instituto Penal Cândido Mendes) and environmental conservation area it becomes the headoffice of the Centro de Estudos Ambientais e Desenvolvimento Sustentável, a State University ofRio de Janeiro (UERJ) unit, which has both an institutional and environmental conservation use,however framed in touristic activity growth context.

A Reserva Biológica Estadual da Praia do Sul (Ilha Grande, RJ) é um importante remanescente de restinga preservada do Rio de Janeiro. A vegetação das restingas não é homogênea, distribuindo-se em zonas de vegetação, e cada uma delas é caracterizada por sua topografia, fisionomia e florística distintas. Estudamos a comunidade de Bromeliaceae, analisando variações na riqueza, abundância, densidade e freqüência de ocorrência entre quatro zonas de vegetação. Nas quatro zonas, amostramos um total de 150 parcelas de 100 m² cada, onde contabilizamos as espécies e suas abundâncias, e medidas de estrutura da vegetação (altura e DAP das árvores e densidade de árvores e de arbustos do sub-bosque). Testamos diferenças entre zonas na abundância de rosetas e na estrutura da vegetação, e entre as abundâncias das espécies de bromélias através de ANOVA seguida do teste de Tukey. Encontramos 16 espécies de bromélias, com abundâncias e padrões de distribuição distintos entre as zonas, além de diferenças significativas entre as abundâncias das espécies. Os dados indicam que a elevada riqueza de espécies encontradas na RBEPS pode estar relacionada à heterogeneidade e à complexidade locais. As diferenças encontradas entre as zonas de vegetação podem ser devidas às diferenças na estrutura da vegetação de cada zona.The Praia do Sul State Biological Reserve (Ilha Grande, RJ) is an important remnant of Restinga habitat in Rio de Janeiro State. Restinga vegetation is not homogeneous and it is distributed in different vegetation zones, each zone having different topography, physiognomy and flora. We analyzed ecological parameters of the bromeliad community such as richness, abundance, density, biomass and variation in species composition in four vegetation zones. We sampled 150 plots of 100 m² (10×10 m), distributed in the four vegetation zones, recording the bromeliad species and their abundance, and measuring the height, dbh, and density of the trees. We tested differences in ramet abundance and vegetation complexity between the four vegetation zones with ANOVA followed by Tukey's test. We found a total of 16 bromeliad species, with different abundances and distribution patterns between the four vegetation zones, and with significant differences in abundance between species. The data indicate that the high species richness found in the Biological Reserve is related to local heterogeneity and complexity. The differences found between vegetation zones seem to be related to the vegetation structure of each zone.

This paper presents the limnological analysis and land use and cover's map of the watershed stream of Ilha Grande, in Presidente Bernardes-SP in Pontal do Paranapanema. The limnological study occurred in five sampling sections analyzing the limnological variables dissolved oxygen, pH, electrical conductivity, water temperature, ammonia and turbidity through parametric Multiprobe brand model Hanna HI 9829 and fractions of dissolved phosphorus, soluble phosphorus and total phosphorus by Mackereth, Heron and Talling (1978). The map was done in ArcGIS 10.2 software using orthophotos of Emplasa of 2011, as result the predominant land use was pasture, with the existence of areas without riparian vegetation, causing erosion problems. Analysing the limnological data, it was observed that most of the parameters was according to CONAMA Resolution 357/05 and the parameters not established by the resolution did not show great variations in most sections.

In August 2014, we performed Rapid Assessment Surveys (RAS) in seven marinas along circa 70 km of the coastline of Ilha Grande Bay (IGB), southeastern Brazil to evaluate diversity in the Ascidiacea and of introduced species. This region is very important for marine biodiversity and includes many protected areas. However, urbanization, tourism and economic development (aquaculture, fisheries, commercial ports and nuclear energy generation) are some of the impacts and drivers of species introduction. Our survey found 16 species, only one native, two introduced and eleven cryptogenic. Two species could not be identified precisely. The most species-rich marina had 11 species and the most polluted three marinas had only six species each. Comparisons with literature indicated that marinas in the IGB had fewer species and fewer introductions than marinas in the São Sebastião Channel (São Paulo), in the same biogeographic region. Future monitoring should consider complementary methods such as passive collectors deployed during summer time and RAS in at least two different times of the year. [ABSTRACT FROM AUTHOR]

Este trabalho analisa as implicações da introdução do turismo na Ilha Grande (Angra dos Reis, RJ), em especial para a população da Vila do Abraão, que foi abruptamente transformada num local de grande procura por parte de turistas e veranistas. Outros casos já estudados indicam um modelo das conseqüências da introdução do turismo em contextos nos quais ele antes não existia, o que é ilustrado com o caso do Abraão. Particularmente a questão da polaridade entre "nativos" e "não-nativos" aflora ali em razão da intensificação do turismo, correspondendo a uma barreira na aceitação de uma ideologia ambientalista e de propostas generalizantes para o que seria "um desenvolvimento turístico ideal".

O objetivo deste artigo é analisar o uso da memória pelas Ciências Sociais a partir da investigação de fontes orais e escritas. Ao longo do trabalho, serão consideradas cinco narrativas sobre o assassinato de um lavrador da Ilha Grande por um grupo de presos que havia fugido do Instituto Penal Cândido Mendes (IPCM). Além disso, são objetos de análise a notícia sobre o caso que aparece na imprensa e o relatório oficial sobre a fuga dos presos encaminhado pelo diretor da penitenciária ao diretor-geral do Departamento do Sistema Penitenciário (DESIPE). Em que pese a diferença entre os relatos apresentados, procurar-se-á mostrar que as memórias relacionam-se a perspectivas e códigos existentes entre grupos de pertencimento e que elas podem fornecer dados importantes sobre contextos, processos e conflitos sociais que fazem parte da vida dos diversos narradores do caso em questão.The objective of this paper is to investigate social practices developed by inmates of the Instituto Penal Cândido Mendes (IPCM) as well as by those who lived in Ilha Grande, the island where the prison was settled, through the analysis of different narratives about the escape of a group of convicts. The author also analyzed the escape on the news and on the official reports. The point the author makes is that despite the different reports on the escape it is possible to relate the narrative to collective memories, that is, to common rules and perspectives, which allow us to understand social conflicts, processes and contexts inherent to the lives of the narrators.

The State Park of Ilha Grande is only a part (5,594 hectares) of the entire island (19,300 hectares) which is located off the south coast of Rio de Janeiro state, between the cities of Mangaratiba and Angra dos Reis. Approximately half of the Park area (47%) is covered by dense Atlantic forest. The secondary forest growth is in a process of ecological succession close to attaining maturity (43%) and the remaining part (10%) is composed of human-altered areas (1%), rocky outcrops with herbaceous vegetation (7%), mangroves and beaches (2%). The fauna is well represented but already shows signs of degradation with introduced species. The analysis of the degree of threat has shown that the dense forest habitat has a relatively stable status of conservation while the secondary forest, the mangrove and the herbaceous vegetation on rocky outcrops (and their fauna) are categorized as vulnerable. The area altered by human occupation is considered threatened. Since the coastal area where Ilha Grande is located is well known for its beautiful scenery (known as the green coast, because of the contrast between the ocean and the Atlantic forest covering the Serra do Mar mountain chain). There is a strong possibility for tourism to become the means in which to achieve economic sustainability for conservation. Contradictorily, tourism is also the major threat to local biodiversity and its landscape units. Because tourism is not organized and controlled, during high season the numbers grow above local capacity, giving rise to a proliferation of hotels, guesthouses and camping grounds. The resulting untreated open sewage, random garbage disposal and other harmful activities form the major threats to biodiversity.

Na Reserva foram encontradas 121 espécies, sendo 27 de Chlorophyceae, 21 de Phaeophyceae e 73 de Rhodophyceae. Dentre estas espécies, 38 são novas referências para a ilha, sendo que Cladophora catenata (L.) Kütz. é pela primeira vez citada para o litoral do Rio de Janeiro. Não foram encontradas espécies endêmicas e nem flora específica de região insular. A comparação da flora da Reserva com a de regiões vizinhas indica alta percentagem de espécies em comum entre elas.A survey in the Reserve showed 27 species of Chlorophyceae, 21 of Phaeophyceae and 73 of Rhodophyceae. Among the recorded species, 38 are new references to the Island and Cladophora catenata (L.) Kütz. is for the first time quoted to the Rio de Janeiro coast. Neither endemic species nor specific flora from insular area were found in the Reserve. A comparison between the flora of the Reserve and those of neighboring areas, showed a high percentage of similarity.

Ilha Grande is a Brazilian island that has a high vegetal biodiversity with a well-documented prehistoric human occupation but has few paleoenvironmental studies developed in this area. In view of this, multiproxy analysis of lagoonal sediments including radiocarbon dating were carried out on a 139 cm-long continental sediment core. The aim of our study was to recognise and explain environmental dynamics in this region during the Holocene (∼5200 cal yr BP). The palynomorphs indicate the continuous presence of Atlantic Forest under humid conditions during the last Holocene sea-level highstand, after 5200 cal yr BP. A phase of low palynomorph concentrations was followed by a marked increase in palynomorph accumulation and diversity which may be linked to the subsequent drop of the sea-level. Dinoflagellate cysts showed a higher accumulation at the base of the sediment core. The high accumulation of charcoal particles identified between approximately 3700 and 3000 cal years BP might indicate human activity related to the long-lasting bonfires kept burning by the inhabitants of the archaeological site of Ilhote do Leste.

Phosphorus, manganese, sulfur (S), lead, and strontium of atmospheric total suspended particulate matter, sampled during the rainy season and the dry season 2002 at the Ilha Grande Island (Rio de Janeiro State, Brazil) have been analyzed by XRF techniques. The results showed total mean concentrations of 27 ± 16 ng P m, 11 ± 7 ng Mn m, 159 ± 126 ng S m, 4.3 ± 2.6 ng Pb m, and 208 ± 148 ng Sr m. Generally, there is no clear influence of the two different climatic periods on the concentrations of most analyzed trace elements, with exception of sulfur the mean concentration of which, during the dry season, is about 60% higher than during the rainy season. This is probably due to biomass burning, a common practice in the Brazilian Southeast and Amazon region and/or to the presence of marine aerosols. The linear correlation coefficients strongly suggest the same source for P, Pb, and Mn. Some Pb, Mn, and P concentrations are in the range of typical values of urban areas. Potential sources of such elements are the urban and industrial emissions from the States of Rio de Janeiro and/or São Paulo. [ABSTRACT FROM AUTHOR]

O objetivo deste trabalho é mostrar três desafios surgidos a partir das primeiras apresentações do projeto Ecomuseu Ilha Grande, todos eles relacionados às diferentes formas de compreensão do que sejam natureza e cultura. O primeiro diz respeito ao equilíbrio entre preservação da natureza e bem-estar dos moradores, objetivos bastante conflitantes atualmente. Em segundo lugar, há a intenção de envolver a população local da Ilha Grande nos projetos de pesquisa acadêmica e de defesa do meio ambiente. Finalmente, há a tentativa de preservar a memória de práticas de violência e de arbitrariedade ética e moral, que são ou estereotipadas ou totalmente ignoradas pela sociedade.The article points to three challenges that arose during initial presentations of the Ilha Grande Ecomuseum project, all of which involved different ways of understanding what constitutes 'nature' and 'culture'. The first issue had to do with balancing environmental protection with the welfare of residents, two aspirations that are quite conflicting at present.
