Reconstruir um ecossistema florestal ribeirinho a partir de uma abordagem cientifica, implica em conhecer a diversidade florística, a complexidade dos fenômenos que se desenvolvem nestas formações, compreender os processos que levam a estruturação e manutenção destes ecossistemas no tempo e utilizar estas informações para a elaboração, implantação e condução de projetos de restauração. Neste sentido, este trabalho teve por objetivo (i) identificar e caracterizar a composição florística das florestas estacionais deciduais e semideciduais associadas aos rios da bacia hidrográfica do Formoso - Bonito/MS, Perdido e Salobra ocorrentes no Parque Nacional da Serra da Bodoquena; (ii) caracterizar a degradação histórica e atual dos fragmentos florestais em estudo; (iii) ordenar e classificar a composição florística em grupos sucessionais e funcionais, visando determinar as correlações entre as formações florestais como base fundamental para definição diferenciada das ações de restauração e conservação. O levantamento florístico foi realizado mensalmente entre o período de outubro de 2004 a março de 2006, onde foram coletadas fanerógamas em fase reprodutiva, através do método de tempo de avaliação com um total de 576 horas. O levantamento florístico resultou em 56 famílias, 184 gêneros e 307 espécies. A família Fabaceae, representada por 51 espécies, foi a de maior riqueza. Do total das espécies, 68% apresentaram hábito arbóreo, 17% arbustos, 14% foram lianas e apenas 1% palmeiras. O método tempo de avaliação adotado, mostrou-se eficiente e de fácil aplicabilidade em locais de difícil acesso e locomoção pela floresta, permitindo um maior deslocamento para a amostragem dos indivíduos, contornando a distribuição espacial das espécies, e refletindo melhor a heterogeneidade ambiental característica das florestas ribeirinhas. Os espécimes foram classificados segundo o seu grupo ecológico, nas categorias pioneiras, secundária e clímax, e através dos grupos funcionais (preenchimento e diversidade). Na bacia hidrográfica do rio Formoso, obtivemos 28% das espécies pioneiras, 46% secundárias, 8% clímax e 18% não classificadas. Quanto ao grupo funcional, 56% das espécies são de preenchimento e 44% de diversidade. Para a bacia do Perdido, classificou-se 24% das espécies como pioneiras, 42% secundárias, 8% clímax e 26% não foram classificadas. O grupo funcional apresentou 54% espécies de preenchimento e 46% diversidade. Na bacia do Salobra obtivemos 31% de espécies pioneiras, 36% secundárias, 5% clímax e 28% não classificadas. A classificação quanto ao grupo funcional, foi de 59% preenchimento e 41% espécies de diversidade. O histórico de uso de cada um dos trechos caracterizados florísticamente foi obtido através dos processos de projetos de Manejo Florestal com pedido no IBAMA desde o ano 1986, onde foram registrados 10.900 ha com pedido de retirada seletiva de madeira. O estado de conservação atual dos trechos florestais amostrados foi classificado em: pouco degradada, degradada e muito degradada, através de indicadores ambientais. Os resultados obtidos neste trabalho contribuíram para o conhecimento da flora sul-mato-grossense e suas distribuições geográficas, reforçaram a necessidade de conservação destas matas ribeirinhas e forneceram subsídios para os planos de restauração das áreas degradadas do entorno da unidade de conservação e das áreas de proteção permanente (APP\'s) dos rios da Serra da Bodoquena. / To reconstruct a riverside forest ecosystem from a scientific version, implies in knowing the floristic diversity and the phenomena complexity that develop in these formations, to understand the processes that take the structuration and maintenance of these ecosystems in the time and to use these information to the elaboration, implantation and conduction of restoration projects. In this direction, this work had as objective (i) to identify and to characterize the floristic composition of the seasonal decidual and semideciduous forests associated to the rivers of Formoso hydrographic basin-Bonito/MS, Perdido and Salobra, that occur in Bodoquena Plateau National Park; (ii) to characterize the historical and current degradation of the forest pieces in study; (iii) to establish and to classify the floristic composition in sucessionais and functional groups, aiming to determine the correlations between the forest formations as basic base to differentiated definition of restoration and conservation actions. The floristic survey was carried monthly, during the period from October 2004 to March 2006, where they had been collected fanerógamas in reproductive phase, through the method of time of evaluation with a total of 576 hours. The floristic survey resulted in 56 families, 184 sorts and 307 species. The Fabaceae family, represented by 51 species, was one of the bigger wealth. Of the total of the species, 68% had presented tree habit, 17% shrubs, 14% had been lianas and only 1% palms. The method time of evaluation adopted revealed itself efficient and of easy applicability in places of difficult access and locomotion through the forest, allowing a bigger displacement to the individuals sampling, encircling the species space distribution, and better reflecting the ambient heterogeneousy from the riverside forests. The specimens have been classified according to its ecological group, in the pioneering, secondary categories and climax. And through the functional groups -fulfilling and diversity. In the hydrographic basin of Formoso river, we got 28% of the pioneering species, 46% of the secondary, 8% climax and 18% have not been classified. In the functional group, 56% of the species are fulfilling and 44% are diversity. To the Perdido basin, we classified 24% of the species as pioneering, 42% secondary, 8% climax and 26% have not been classified. The functional group presented 54% species fulfilling and 46% diversity. In the Salobra basin we got 31% of pioneering species, 36% secondary, 5% climax and 28% have not been classified. In the functional group classification, it was 59% fulfilling and 41% species of diversity. The description of use of each one of the floristically characterized stretches was gotten through the processes of Forest Handling projects with order in IBAMA since 1986, where they had been registered 10,900 ha with order of selective wooden withdrawal. The current conservation state of the showed forest stretches was classified in: little degraded, degraded and much degraded, through ambient pointers. The results gotten in this work have contributed for the knowledge of Mato Grosso do Sul flora and its geographic distributions have strengthened the necessity of conservation of these riverside forests and have supplied subsidies to the restoration plans of the degraded areas around the unit of conservation and permanent protection areas (APP\'s) of the Bodoquena Plateau rivers.

O presente estudo foi desenvolvido nas planícies costeiras do Itaguaré e do Guaratuba localizadas no município de Bertioga (litoral central do Estado de São Paulo) e teve como objetivo descrever e comparar aspectos florísticos e estruturais das tipologias florestais que ocorrem em diferentes associações com depósitos sedimentares e solos. Foram inventariados 12 florestas: a) Floresta baixa de Restinga sobre cordões litorâneos holocênicos amostrada na planícies costeiras do Guaratuba (FbR/G); b) Floresta baixa de Restinga sobre cordões litorâneos holocênicos presente na planícies costeiras do Itaguaré (FbR/I), c) Floresta alta de Restinga sobre cordões litorâneos holocênicos (FaR1/G), d) Floresta alta de Restinga sobre terraços marinhos holocênicos presente na planícies costeiras do Guaratuba (FaR2/G); e) Floresta alta de Restinga sobre terraços marinhos holocênicos presente na planícies costeiras do Itaguaré (FaR2/I); f) Floresta alta de Restinga sobre terraços marinhos baixos pleistocênicos presente na planícies costeiras do Guaratuba; g) Floresta alta de restinga sobre terraços marinhos baixos pleistocênicos presente na planícies costeiras do Itaguaré (FaR3/I); h) Floresta alta de Restinga úmida sobre depressões estuarinas paleolagunares rasas holocênicas (FaRu) i) Floresta Paludosa sobre sobre depressões paleolagunares profundas holocênicas (FPa); j) Floresta Aluvial sobre terraços fluviais pleistocênicos (FAL), K) Floresta de transição Restinga- Encosta sobre depósitos mistos holocênicos a atuais (FTr1) e L) Floresta de transição Restinga- Encosta sobre depósitos de encostas pleistocênicos a atuais (FTr2). A amostragem foi realizada pelo método de parcelas, sendo incluídos todos os indivíduos com diâmetro a 1,3 m (DAP) 10cm. Na área inventariada, que totalizou 1,2 ha, foram encontradas 130 espécies e 42 famílias botânicas. Foram verificadas diferenças na riqueza e diversidade entre Florestas presentes sobre um mesmo substrato geológico situadas em planícies diferentes. FAL apresentou a maior riqueza e diversidade entre todas as florestas comparadas, A análise da similaridade florística entre as 12 áreas estudadas formou quatro grupos, levando em conta o tipo de substrato geológico e a distância geográfica. A espécie Ilex Theezans Mart. ex Reissek se destacou quanto ao valor de importância (VI) e a densidade relativa (DR) nas duas Florestas baixas de Restinga resultado esse que se repete em outros estudos no litoral de São Paulo, sendo uma espécie potencial para restauração dessa tipologia florestal no estado de São Paulo. Nas Florestas altas de Restinga, Eriotheca pentaphylla (Vell.) A. Robyns de destacou quanto ao VI e DR em quatro florestas (FaR1/G, FaR2/G, FaR3/G e FaR3/I) sendo uma espécie potencial para restauração dessa tipologia na região de estudo. Na FAL, Ocotea dispersa (Nees) Mez foi a espécie que apresentou maior VI, maior DR e maior Dominância relativa (DoR), sendo essa espécie típica da Floresta Ombrófila Densa das Encostas da Serra do Mar. Em SB-FTr1 e SB-FTr2 a espécie Eriotheca pentaphylla se destacou com maior VI, mas apresentou maiores DR e DoR apenas no SB-FTr2. No SB-FTr1 essa espécie apresentou apenas a maior DoR, uma vez que a maior DR foi obtida para Syagrus pseudococos (Raddi) Glassman. Tabebuia cassinoides (Lam.) DC aparece com maior VI e maior DR nas duas florestas sobre depressões estuarinas paleolagunares (FaRu e FPa). Florestas presentes sobre VII substratos continentais (FAL, FTr1 e FTr2) apresentaram maiores desenvolvimento em altura, fato esse provavelmente associado a condições pedológicas e ao nível do lençol freático. As florestas que ocorrem em substratos marinhos mais antigos (pleistoceno) apresentaram árvores mais desenvolvidas em tamanho do que as Florestas altas presentes nos substratos mais novos (holoceno). Os menores valores de correlação entre altura e DAP ocorreram nas Floresta baixa de Restinga, indicando um padrão mais horizontal de dispersão das alturas, onde o incremento em altura não acompanha o incremento em DAP. A análise de componentes principais (PCA) indicou quatro grupos de sub-biomas levando em consideração a variação nos parâmetros químicos dos solos. Todos as florestas apresentaram solos com elevada acidez. Maiores teores de matéria orgânica foram encontrados nas florestas sobre sedimentos continentais que preenchem as depressões estuarinas - paleolagunares, e os menores ocorreram nas florestas baixas de Restinga. Todas as áreas apresentam limitação quanto à fertilidade dos solos. / This work was done in the Guaratuba and Itaguare coast plains in Bertioga (central coast of São Paulo) and aimed to describe and compare the floristic diversity and phytosociological structure of forest types that occur in different associations with quaternary sediments and soil. A total of 12 forests were sampled: a) Restinga low Forest on Holocene beach ridges in the Guaratuba coast plains (FbR/G), b) Restinga low Forest on Holocene beach ridges in the Itaguaré coast plains (FbR/I), c) Restinga hight Forest on holocene beach ridges (FaR1/G), d) Restinga hight Forest on holocene marine terraces in the Guaratuba coast plains (FaR2/G), e) Restinga hight Forest on holocene marine terraces in the Itaguaré coast plains (FaR2/I), f) Restinga hight Forest on pleistocene marine terraces in the Guaratuba coast plains (FaR3/G); g) Restinga hight Forest on pleistocene marine terraces in the Itaguaré coast plains (FaR3/I), h) wet Restinga hight Forest on holocene estuarine - paleolagoonal shallow depression (FaRu), i) Paludal Forest on holocene paleolagoonal deep depression (FPa), j) Alluvial Forest on pleistocene fluvial terraces (FAL), k) Restinga Slope transition Forest on Holocene to recent Fluvial Deposits (FTr1) and l) Restinga Slope transition Forest on Pleistocene to recent slope deposits). For the sampling the plotting method was used, totaling 1,2 ha of sampled area, being included in the sampling all individuals with diameter at 1,3 m (D.B.H.) 5cm. In total were found 130 species and 42 families. Richness and diversity differences were observed in Forests present on the same geological substrate located in different plains. FAL had the greatest richness and diversity of all forest compared. The analysis of the floristic similarity among the 12 studied areas formed four groups, taking into account the type of geological substratum and geographical distance. The Ilex theezans Mart. ex Reissek stood out in importance value (IV) as well as the relative density (RD) in both Restinga low Forest, this result is repeated in other studies on the coast of São Paulo, being a species potential to restore this forest type in the state of São Paulo. In the Restinga hight Forests, Eriotheca pentaphylla (Vell.) A.Robyns had the highest IV and the greatest RD in four (FaR1/G, FaR2/G, FaR3/G e FaR3/I) of the five sampled areas, being a species potential to restore this forest type in the study region. In FAL Ocotea dispersa (Nees) Mez showed the highest values of IV, RD and relative dominance, indicating the influence of Ombrophylus Dense Forest present in the slopes of the Serra do Mar on the FAL. In the FTr1 and FTr2 Eriotheca pentaphylla stood out with the greatest IV, but it appears with the greatest RD and relative dominance only in the SB-FTr2. In SB-FTr1 this species has only the highest relative dominant being the highest DR for Syagrus pseudococos (Raddi) Glassman. Tabebuia cassinoides (Lam.) DC appears with the highest VI and DR in the two forest on the estuarine - paleolagoonal depression (FaRu and FPA). The biggest height development occurred in the forest on the continental sediments (FAL, FTr1 e FTr2), this fact was probably associated with soil conditions and groundwater level. The Restinga hight Forests that occur on older marine substrates had more developed trees in hight than the Restinga hight IX Forests that occur in the younger substrates. The lowest correlation value between height and DBH occurred in sub-biomes formed by the Restinga low Forest, indicating a more horizontal dispersion of the heights, where the increase in height does not follow the increase in DBH. The principal component analysis (PCA) indicated four groups of sub-biomes, taking into account the variation in chemical soil parameters. All forests showed soils with high acidity. Higher organic matter amounts were found in forests formed by estuarine - paleolagoon sediments (FaRu and FPa) and the lowest occurred in two Restinga low Forest. All areas have soils with low fertility.

A bacia do rio Paraíba do Sul (sudeste do Brasil) está inserida no domínio da Floresta Atlântica, em altitudes que vão do nível do mar até 2797 metros. Há grande complexidade topográfica e climática, que resulta na presença de inúmeras fitofisionomias, como os Campos de altitude, Cerrado, Floresta Estacional Semidecidual e Florestas Ombrófilas Densa e Mista. Apesar da grande complexidade florestal, esta bacia ainda não foi objeto de estudos fitogeográficos. Análises das relações de similaridade florística entre comunidades arbóreas conduz em geral ao estabelecimento de padõres condicionados por fatores diversos que determinam a ocorrência das espécies. As florestas estacionais semideciduais da bacia do rio Paraíba do Sul mostram-se bastante fragmentadas e têm sido pouco estudadas do ponto de vista florístico e fitossociológico. O presente estudo objetivou conhecer e comparar a composição florística, a estrutura e os aspectos ecológicos do componente arbóreo de três fragmentos. Além disso, foram utilizadas análises de agrupamento e correspondência para estabelecer comparações florísticas com outras 31 áreas de Floresta Atlântica, 17 delas pertencentes à bacia do rio Paraíba do Sul (bacia do RPS). O fragmento maior (300 ha) situa-se no município de Areias e os dois menores (14 ha cada) em São José do Barreiro (22°41\'S; 44°3\'W), ambos no Estado de São Paulo. Para a amostragem, foram lançados 135 pontos quadrantes em cada um dos fragmentos, e incluídos os indivíduos com PAP≥ 15cm. Foram encontrados 1.620 indivíduos, 227 espécies, 138 gêneros e 51 famílias. As coletas extensivas acresceram 64 espécies, totalizando 290. As famílias Leguminosae, Myrtaceae, Rubiaceae, Lauraceae, Euphorbiaceae e Annonaceae apresentaram a maior riqueza de espécies. A riqueza de espécies variou entre 165 e 178, a partir da amostragem total, e os índices de diversidade variaram entre 3,88 e 4,4. Há 13 novos registros citados para o Estado de São Paulo (e.g. Casearia selloana, Mollinedia longifolia, Pseudolmedia hirtula), com a presença de cinco espécies ameaçadas (Dalbergia nigra, Melanoxylon brauna, Mollinedia glabra, Ocotea odorifera, Urbanodendron bahiense). Os fragmentos apresentam-se em estágio avançado de sucessão, com predomínio de zoocoria, o que demonstra sua importância ecológica para a manutenção da fauna. As análises florísticas e a composição de espécies indicaram que, apesar de seus caracteres de transição entre florestas estacionais semideciduais e ombrófilas densas, a flora arbórea 188 dos fragmentos tem laços mais fortes com as primeiras. As florestas estacionais semideciduais da bacia do RPS apresentaram maior semelhança com as de mesma fitofisionomia da bacia do rio Doce, sugerindo que ambas correspondam a um contínuo de distribuição. O maior aporte de umidade das bacias RPS e do rio Doce deve ser o principal fator responsável pela distribuição de diversas espécies de forma exclusiva entre as florestas estacionais destas bacias e as florestas ombrófilas. Sugeriu-se que as variáveis mais fortemente ligadas à diferenciação florística entre as florestas comparadas sejam a duração da estação seca (estacionalidade das chuvas), a precipitação total, a altitude e a proximidade espacial entre as áreas. A alta riqueza e o elevado número de espécies de ocorrência restrita ou pouco frequentes na Floresta Atlântica denotam a importância da conservação dos fragmentos de florestas estacionais desta região. Ressaltamos ainda que o Vale do Paraíba paulista não possui unidades de conservação de proteção integral que incluam remanescentes de Floresta Estacional Semidecidual, o que compromete seriamente a conservação de parte importante da biota que é exclusiva deste tipo florestal, como constatado neste estudo. / The Paraíba do Sul River Basin (southeastern Brazil) is inserted into the Atlantic Rain Forest domain, at elevations from sea leval to 2797 a.s.l.. Ample topografic and climatic complexity is evident, as a result of diverse phytophysionomies, such as the high mountain grassland and savana, as well as seasonal Semi-deciduous, Tropical Rain and Araucaria forests. In spite of evident forest complexity, this basin has not come under the scope of phytogeographical studies. Through an analysis of floristic similarity among tree communities, it is possible to detect species pattern occurrence, as well as to explain conditioning factors. The Seasonal Semi-deciduous Forest of the Vale do Paraíba river basin occurs in highly fragmented areas, and has received but little attention as to floristic and phytosociological factors. With this in mind, the aim was to characterize and compare pertinent aspects of floristic composition, structure and ecology. The study areas were compared with other forests in the Atlantic domain, 17 of which occurring in this basin (RPS basin). Attention was focused on three fragments, two of 14 ha and another of 300.. 135 quarter-centered-points were sampled in each 189 fragment, by considering trees with circumferences equal or wider than 15 cm. 1620 individuals, belonging to 227 species, 138 genera and 51 families, were recorded. 64 species were compounded by random collectioning, to a total of 290. Those families with the highest number of species were Leguminosae, Myrtaceae, Rubiaceae, Lauraceae, Euphorbiaceae and Annonaceae. The total number of species varied from 165 to 178, and Shannon diversity indexes from 3,88 to 4,4. 13 species were first-time- encounters in São Paulo state (e.g. Casearia selloana, Mollinedia longifolia, Pseudolmedia hirtula), and five threatened (Dalbergia nigra, Melanoxylon brauna, Mollinedia glabra, Ocotea odorifera, Urbanodendron bahiense). The fragments were in advanced stages of succession, with predominant zoochory, making their maintenance essential in regional fauna conservation. Through the analysis of floristic and species composition, there was every indication that, in spite of the transitional character between seasonal semi-deciduous and dense ombrophylous forests, there was a stronger link of tree-flora fragments with the former. There was greater similarity between the seasonal semi-deciduous forests of the Paraíba do Sul and those of the Doce river basins, thereby implying continuous distribution. Higher humidity could be the main factor inducing the exclusive distribution of many species among seasonal semi- deciduous forests of the Paraíba do Sul and Doce river basins, as well as dense ombrophylous forests. We suggest that variables, such as rainfall seasonality and volume, altitude and spatial proximity, are those that most strongly influence floristic differences. The richness and number of rare and restricted species emphasize the importance of preserving these regional fragments. In the Paraíba do Sul River Basin, there are no conservation units that include remnant semi-deciduous forest. This aspect seriously compromises the conservation of a unique biota, exclusive to this type of forest.

Fundação Carlos Chagas Filho de Amparo a Pesquisa do Estado do Rio de Janeiro / O estudo objetivou avaliar a composição florística e estrutural dos componentes arbustivo-arbóreo da Floresta Ombrófila Densa submontana em diferentes estágios de regeneração natural, na vertente sudeste do Parque Estadual da Ilha Grande/RJ. Para o inventário florístico foram realizadas coletas assistemáticas em diferentes trechos nessa vertente. A complementação da lista de espécies foi feita a partir, da consulta às exsicatas dos herbários do Rio de Janeiro (FCAB, GUA, HB, HRJ, R, RB, RBR, RFA, RFFP e RUSU) e do inventário fitossociológico. Foi verificado o status de conservação das espécies inventariadas para a Flora Brasileira. Para o inventário fitossociológico foram estabelecidas 34 parcelas amostrais, totalizando 1,02 ha de área amostrada. Todos os indivíduos arbustivo-arbóreos com DAP ≥ 5 cm foram registrados e, após identificação, foram depositados no Herbário da Universidade do Estado do Rio de Janeiro (HRJ). O pacote estatístico FITOPAC 2.1. foi utilizado para a análise dos dados. A similaridade entre o remanescente investigado neste estudo e as outras quatorze áreas distintas do Rio de Janeiro, da própria Ilha Grande ou não, foi avaliada, utilizando-se o coeficiente de Similaridade de Sorensen; pelo critério de agrupamento por ligação média não ponderada (UPGMA) e pelo método de autorreamostragem para a estrutura de grupos; utilizados os programas PAST v1.34 e Multiv 2.4. A partir do levantamento em herbários e dos inventários florístico e fitossociológico realizados neste trabalho, foram analisados 3.470 registros, sendo 1.778 do levantamento de herbários, 1.536 do levantamento fitossociológico e 156 do inventário florístico. Esses registros corresponderam a 606 espécies ou morfo-espécies de Angiospermas e uma de Pteridófita. Os resultados obtidos revelaram a existência de 22 espécies ameaçadas de extinção para a Flora do Brasil. Dentre, as quais, sete são exclusivas da amostragem fitossociológica: Abarema cochliacarpos (Gomes) Barneby & J.W. Grimes, Chrysophyllum flexuosum Mart., Ficus pulchella Schott ex Spreng., Macrotorus utriculatus Perkins, Myrceugenia myrcioides (Cambess.) O.Berg, Rudgea interrupta Benth e Urbanodendron bahiense (Meisn.) Rohwer. No estudo fitossociológico, inventariou-se 1.536 indivíduos de 217 espécies, subordinadas a 53 famílias. O índice de diversidade de Shannon (H) calculado foi de 4,702 nats/ind e equabilidade (J) de 0,874. As 10 famílias com maior riqueza foram: Myrtaceae (31 spp.), Rubiaceae (21), Fabaceae (17), Lauraceae (12), Euphorbiaceae (11), Monimiaceae (8), Melastomataceae (7), Sapindaceae (7), Sapotaceae (6) e Annonaceae (6). Os 10 maiores Valores de Importância das espécies foram para Chrysophyllum flexuosum (3,43%), Lamanonia ternata Vell. (3,40%), Hyeronima alchorneoides Allemão (2,83%), Actinostemon verticillatus (Klotzsch) Baill. (2,55%), Psychotria brasiliensis Vell. (2,55%), Eriotheca pentaphylla (Vell.) A. Robyns (2,28%), Guatteria australis A. St.-Hil. (2,12%), Mabea brasiliensis Müll. Arg. (2,04%), Miconia prasina (Sw.) DC. (1,89%) e Rustia formosa (Cham. & Schltdl. ex DC.) Klotzsch (1,82%). Amostraram-se 27% de espécies representadas por apenas um indivíduo. As análises florísticas avaliadas a partir do Índice de Similaridade de Sorensen indicaram como principais variáveis para a formação dos blocos, os diferentes valores de diversidade para as áreas e a distribuição fitogeográfica das espécies. Os resultados obtidos junto aos dados dos grupos ecológicos, para os indivíduos da fitossociologia, indicaram maior percentual de indivíduos secundários tardios amostrados. Conclui-se que a área de estudo é uma floresta secundária em estágio intermediário de regeneração, com grande riqueza de espécies, muitas das quais de relevante importância ecológica. / The study has as purpose to evaluate the floristic and structural composition of shrub-arboreal component in the submontane forest patch within the Atlantic Rain Forest domain with different stages of natural regeneration, in the southeast slope at the State Park of Ilha Grande, RJ. For the floristic studies were realized unsystematic samples in different parts in this slope. The species list was complemented with the conference at herbarium collections of the Rio de Janeiro (FCAB, GUA, HB, HRJ, R, RB, RBR, RFA, RFFP e RUSU) and with the results obtained of phytosociological studies. The conservation status of recorded species was verified for the Brazilian Flora. 34 plots of samples were set out for the phytosociological studies, totaling 1.02 ha of sampled area. All shrubby-arboreous individuals with DAP ≥ 5 cm were registered and, after identification, were deposited in the Herbarium of the Universidade do Estado do Rio de Janeiro (HRJ). The statistical package FITOPAC 2.1. was used for data analysis. The similarity between the remaining investigated in this study and fourteen others from different areas of Rio de Janeiro, of llha Grande's itself or not, was evaluated using the similarity coefficient of Sorensen; by Unweighted Pair Group Method with Arithmetic Mean (UPGMA) criterion and by the auto-resampling method for the structure of groups; by using the programs PAST v1.34 and Multiv 2.4. From the survey in herbariums and from floristic and phytosociological inventories carried in this paper, were examined 3,470 registers: 1,778 of the survey in herbariums, 1,536 of phytosociological and 156 of floristic studies. These registers corresponded to 606 species or morpho-species of Angiosperms and one of Pteridophyte. The results revealed the existence of 22 species threatened by extinction for Brazilian Flora. From among which, seven are exclusive of phytosociological sampling: Abarema cochliacarpos (Gomes) Barneby & J.W. Grimes, Chrysophyllum flexuosum Mart., Ficus pulchella Schott ex Spreng., Macrotorus utriculatus Perkins, Myrceugenia myrcioides (Cambess.) O.Berg, Rudgea interrupta Benth and Urbanodendron bahiense (Meisn.) Rohwer. In phytosociological study, were inventoried 1,536 individuals of 217 species, subordinate to 53 families. The Shannon diversity indices (H ') calculated was 4,702 nats/ind and equability (J) of 0.874. The ten families with highest richness were: Myrtaceae (31 spp.), Rubiaceae (21), Fabaceae (17), Lauraceae (12), Euphorbiaceae (11), Monimiaceae (8), Melastomataceae (7), Sapindaceae (7), Sapotaceae (6) and Annonaceae (6). The 10 highest values for species importance were for Chrysophyllum flexuosum (3,43%), Lamanonia ternata Vell. (3,40%), Hyeronima alchorneoides Allemão (2,83%), Actinostemon verticillatus (Klotzsch) Baill. (2,55%), Psychotria brasiliensis Vell. (2,55%), Eriotheca pentaphylla (Vell.) A. Robyns (2,28%), Guatteria australis A. St.-Hil. (2,12%), Mabea brasiliensis Müll. Arg. (2,04%), Miconia prasina (Sw.) DC. (1,89%) and Rustia formosa (Cham. & Schltdl. ex DC.) Klotzsch (1,82%). Were sampled 27% species represented by only one individual. The Floristic analyzes evaluated from the Sorensen Similarity Index indicated as the main variables for the formation of blocks, the different values of diversity for the areas and the phytogeographical distribution of species. The results obtained along with data from ecological groups, for individuals of the phytosociology, indicated a higher percentage of secondaries tardy individuals sampled. It Concludes that the study area is a secondary forest in regeneration intermediate stage, with great richness of species, many of which with relevant ecological importance

Os objetivos foram: i) investigar as relações entre a estrutura da comunidade e a distribuição das espécies em relação às condições do substrato (propriedades químicas, granulometria e drenagem) e entrada de luz (abertura do dossel), para cada floresta; ii) avaliar as relações de similaridade e diferenças florísticas entre as florestas paludosas interioranas do sudeste e centro-oeste do Brasil. A floresta paludosa de Itirapina constitui-se de um capão naturalmente isolado de outras formações florestais, em meio a campos úmidos. As florestas de Cristais Paulista e Jeriquara são fragmentadas por ação antrópica, encontram-se em contato com manchas de cerrado (principalmente cerradão) e são caracterizadas por aclives no sentido interior-borda. Em cada floresta foram estabelecidas 60 parcelas de 10 x 10 m, onde foram quantificados e identificados os indivíduos com PAP > 10 cm, classificados os solos e avaliadas suas propriedades químicas, textura, drenagem e, ainda, estimada a abertura de dossel. Nas três florestas foram quantificados 9.725 indivíduos, distribuídos em 109 espécies. Observou-se uma relação positiva entre o número de classes de solos e o número de espécies amostradas em cada floresta, com 37 espécies encontradas em Itirapina (sobre apenas uma única classe de solo), 61 em Cristais Paulista (sobre duas classes) e 72 em Jeriquara (sobre três classes). Além das condições edáficas, o contato das florestas com cerradão em Cristais Paulista e Jeriquara, possibilita a coexistência de espécies higrófilas e de cerrado... / Floristics and structural characterization of three swamp forests located in the countryside of São Paulo state (municipalities of Itirapina – 22o15’54’’S, 47o40’51’’W, Cristais Paulista – 20o25’58’’S, 47o25’98’’W and Jeriquara – 20o19’30’’S, 47o37’10’’W) were conducted with the following objectives: i) to investigate the relationships between community structure, species distribution, substrate (chemical properties, texture and drainage) and light entrance (canopy openness) for each forest; ii) to evaluate floristics similarities and differences amongst the swamp forests in countryside of southeastern and central-western Brazil. The Itirapina swamp forest is naturally isolated from other forests formations, because it is surrounded by wet fields. Cristais Paulista and Jeriquara swamp forests were fragmented by human action and occur in contact with patches of cerrado (mainly cerradão). They were characterized by slope towards stream-edge. In each forest, 60 quadrats of 10 x 10 m were established, which all individuals with CBH > 10 cm were quantified and identified. Soil was classified and evaluated by its chemical properties, texture and drainage, and canopy openness was also estimated. On the three forests 9,725 individuals were sampled, distributed in 109 species. It was found a positive relationship between the number of soil’s classes and the number of species in each forest, with 37 species found in Itirapina (on only one class of soil), 61 in Cristais Paulista (on two soil classes) and 72 in Jeriquara (on three classes). Apart from soil conditions, the contact with Cristais Paulista and Jeriquara swamp forests with cerradão allows the coexistence of hygrophilous and savannas species, which was not observed in Itirapina forest because of its spatial isolation. A Canonical correspondence analysis showed... (Complete abstract click electronic access below)

They show minimal resilience levels and need antropogenic interference for rehabilitation in the regional context. In this study it was evaluated 5 reforestations with different species and functional properties (treatments) after a lapse of 13-years. In chapter 1 it was evaluated the development, horizontal structure and floristic composition of shrubby-arboreal stratum. In chapter 2 understory spontaneous regeneration and in chapter 3 similarity of floristic composition between rehabilitation and a spontaneous restored area (~ 40 years old) were determined. At reforestation sites with five different groups of species, floristic composition increased from 12 to 23 species, distributed on 12 families and 276 individuals, where Fabaceae was the major family. For spontaneous regeneration 3.554 individuals were surveyed (1.438 on winter and 2.116 at summer) and the most representative families were Asteraceae and Poaceae. At the restoration site, it was observed 967 individuals from spontaneous regeneration, and the most representative families were Asteraceae and Sapindaceae, showing that there is low similarity between rehabilitation and restoration environments. All treatments displayed advances in the environmental sustainability, but two combinations of species had different performances in the rehabilitation of the reclaimed areas. / ?reas de empr?stimo constituem ecossistemas onde o solo e partes do subsolo foram suprimidas.

Tallgrass prairie restoration is an important conservation activity in rural areas. However, little is known about prairie restoration in urban environments. The overall objective of this study was to characterize and better understand urban prairie restoration. This was carried out through an examination of 29 restoration sites within Winnipeg, Manitoba. The results indicated that actively restored urban prairies were successful and high in diversity. Multiple attributes of the restorations were examined as indicators of success including vegetation, the propagule bank and insects. However, not all attributes delivered equivocal results. This suggests that multiple measures should be used to assess a restoration site. Anthropogenic and biophysical variables were found to influence vegetation of the restorations equally, highlighting the importance of incorporating a human component in urban ecological research. These urban restorations were seen to surpass larger rural restorations in quality; thus, efforts should be made to increase their prevalence. / February 2008

Η περιοχή έρευνας αποτελείται από την οροσειρά του Ελικώνα, το όρος Ξεροβούνι και τμήμα του όρους Νεραϊδολάκκωμα. Οι ορεινοί αυτοί όγκοι βρίσκονται στη Στερεά Ελλάδα και συγκεκριμένα στο νομό Βοιωτίας. Στην παρούσα εργασία εξετάζουμε τις πληροφορίες που αφορούν στο αβιοτικό περιβάλλον, όπως τοπογραφικές, γεωλογικές, κλιματικές και βιοκλιματικές. Η χλωρίδα της εξεταζόμενης περιοχής αποτελείται από 1273 taxa, από οποία τα 17 είναι Πτεριδόφυτα και τα 1256 Σπερματόφυτα. Το μεγαλύτερο μέρος των βιβλιογραφικών δεδομένων και συγκεκριμένα τα 335 από τα 448 taxa επιβεβαιώθηκαν, ενώ εντοπίστηκαν 825 νέα φυτικά taxa, αριθμός που αντιπροσωπεύει περίπου το 65% της χλωρίδας μας. Από την ανάλυση του βιοφάσματος της χλωρίδας μας προκύπτει πως το υψηλό ποσοστό συμμετοχής (35,35 %) των θεροφύτων, αντικατοπτρίζει ένα μεσογειακού τύπου κλίμα, κύριο χαρακτηριστικό του οποίου είναι η παρατεταμένη θερμή και ξηρή περίοδος. Από την άλλη μεριά το σημαντικό ποσοστό των ημικρυπτοφύτων που ακολουθεί με μικρή διαφορά (32,83%) δείχνει την ισχυρή επίδραση που ασκεί το ορεινό ανάγλυφο της περιοχής στη σύνθεση της χλωρίδας μας. Η ενότητα των Βαλκανικών γεωστοιχείων αντιπροσωπεύεται από 127 taxa (10,03%). Από αυτά, τα 72 taxa χαρακτηρίζονται ως ενδημικά Βαλκανικά, ενώ τα 55 είναι Βαλκανικά Υπενδημικά. Το ποσοστό ελληνικών ενδημικών ειδών ανέρχεται στο 9,16% της χλωρίδας των ορέων μας και αντιστοιχεί σε 116 taxa. Ο μεγάλος αριθμός ενδημικών γεωστοιχείων που καταγράφεται στην περιοχή μελέτης οφείλεται σε ένα σύνολο παραγόντων. Μεταξύ αυτών περιλαμβάνονται: οι ποικίλες μονάδες βλάστησης που αναπτύσσονται στην εξαιρετικά εκτενή περιοχή μελέτης, η οποία εκτείνεται από το επίπεδο της θάλασσας έως την ανωδασική ζώνη, αλλά και η παρουσία οικοτόπων με ξεχωριστή οικολογία. Σημαντικό όμως ρόλο φαίνεται πώς έχει διαδραματίσει η γεωγραφική θέση της περιοχής μας και η εγγύτητα αυτής με την Πελοπόννησο, την Εύβοια, όσο και με τα χαμηλά όρη της Ανατ. Στερεάς (Γεράνεια, Κιθαιρώνας, Πατέρας) αλλά και υψηλά όρη που βρίσκονται δυτικότερα (Παρνασσός, Γκιώνα, Βαρδούσια). Πέραν των παραπάνω η παλαιογεωγραφία και η απουσία ισχυρών φυτογεωγραφικών εμποδίων αποτελούν παράγοντες που ευνόησαν τον εμπλουτισμό των ορέων που ερευνώνται με ενδιαφέροντα ενδημικά γεωστοιχεία. Μεταξύ των φυτικών στοιχείων που διαμορφώνουν την χλωρίδα της περιοχής περιλαμβάνονται 65 taxa τα οποία θεωρούνται σημαντικά λόγω της σπανιότητας και των απειλών που αυτά δέχονται. Τα 6 από αυτά ανήκουν σε μια από τις κατηγορίες ερυθρών δεδομένων του Red Data Book of Rare of Threatened Plants of Greece (Phitoς et al, 1996) Συγκεκριμένα 3 taxa χαρακτηρίζονται εύτρωτα (V), 2 σπάνια (R) και 1 κινδυνεύων (E). Επιπλέον 21 φυτικά είδη, εκ των οποίων τα 15 είναι ενδημικά, εντάσσονται σε κάποια από τις κατηγορίες ερυθρών δεδομένων της IUCN (1997). Επικρατεί η κατηγορία των σπάνιων (R) με 18 taxa, ενώ 2 taxa χαρακτηρίζονται ως εύτρωτα (V) και 1 ως απειλούμενο. Παράλληλα προχωρήσαμε σε τροποποιήσεις του status επικινδυνότητας ορισμένων στενότοπων ενδημικών ειδών, με βάση τις νέες κατηγορίες της Λίστας Ερυθρών δεδομένων και λαμβάνοντας υπόψη τόσο τα κριτήρια που υιοθετήθηκαν από τη IUCN. (IUCN, 2001), όσο και επιτόπιες παρατηρήσεις που έγιναν τόσο στην περιοχή έρευνας, όσο και σε γειτονικά όρη. Προκειμένου να διερευνήσουμε τις φυτογεωγραφικές σχέσεις του ορεινού συγκροτήματος με τις υπόλοιπες φυτογεωγραφικές περιοχές της Ελλάδας, αλλά και με τα κυριότερα όρη της Στερεάς και Πελοποννήσου χρησιμοποιήσαμε τις εξαπλώσεις των ενδημικών taxa. Έντονη λοιπόν εμφανίζεται η φυτογεωγραφική σύνδεση της περιοχής μας με την Πελοπόννησο, ενώ από τις υπόλοιπες γεωγραφικές περιοχές ξεχωρίζει το Δυτικό Αιγαίο, με την γειτονική και σε κοντινή απόσταση ευρισκόμενη Εύβοια. Τα υψηλά ποσοστά που καταγράφονται και στις δύο περιπτώσεις (76% και 49% αντίστοιχα) σχετίζονται με την παλαιογεωγραφική πορεία των παραπάνω περιοχών και συγκεκριμένα με την πρόσφατη αποχώρηση τους από την Στερεά Ελλάδα, αλλά και από την έλλειψη ισχυρών φυτογεωγραφικών εμποδίων, μιας που τόσο ο θαλάσσιος χώρος του Κορινθιακού όσο και αυτός του Ευβοϊκού δεν απομόνωσαν αποτελεσματικά τις τρεις γεωγραφικές περιοχές. Η ένταση των σχέσεων αυτών βαίνει μειούμενη με την ακόλουθη σειρά: Νότια Πίνδος, Ανατολική-Κεντρική, Βόρεια-Κεντρική Ελλάδα, Ιόνια Νησιά, Κρήτη, Κυκλάδες, Βόρεια Πίνδος κλπ. Προκειμένου να διερευνηθεί η βλάστηση της περιοχής και να διακριθούν οι επιμέρους μονάδες της, επιλέχθηκαν 358 αντιπροσωπευτικές δειγματοληψίες. Κατά τη διάρκεια της συνθετικής φάσης χρησιμοποιήθηκαν σύγχρονες μέθοδοι πολυπαραγοντικής αριθμητικής επεξεργασίας οικολογικών δεδομένων. Για την κατάταξη των δεδομένων βλάστησης χρησιμοποιήθηκε η Detrended Correspondence Analysis (DCA), με τη βοήθεια του λογισμικού πακέτου πολυπαραγοντικής ανάλυσης PC-ORD 4.19 (Multivariate Analysis of Ecological Data, version 3.0 for Windows). Η μέθοδος κατάταξης εφαρμόστηκε συμπληρωματικά με τη μέθοδο ταξινόμησης TWINSPAN. Από την επεξεργασία των δειγματοληψιών διακρίθηκαν 20 φυτοκοινωνίες, 2 υπο-φυτοκοινωνίες και 17 φυτοκοινότητες. Οι μονάδες που περιγράφονται για πρώτη φορά ανέρχονται σε 9. Από αυτές οι 3 αποτελούν νέες φυτοκοινωνίες, ενώ οι υπόλοιπες 6 μονάδες εντάχθηκαν σε ένα απροσδιόριστο ιεραρχικό επίπεδο Ταξινομικού συστήματος, αυτό της κοινότητας. Οι νεοπροσδιοριζόμενες φυτοκοινωνίες εντοπίζονται σε κάθετα ασβεστολιθικά βράχια, ενώ το μεγαλύτερο μέρος των κοινοτήτων απαντώνται σε περιοχές όπου η βλάστηση έχει σημαντικά αλλοιωθεί, εξαιτίας της δράσης του ανθρώπινου παράγοντα, από τα βάθη των αιώνων έως σήμερα. Συγκεκριμένα οι περισσότερες νέες φυτοκοινότητες εντοπίζονται στον ανωδασικό χώρο αλλά και στον ξηρό θερμο-μεσογειακό όροφο βλάστησης. Διαδοχή και εξέλιξη των μονάδων βλάστησης Στην ενότητα αυτή παραθέτουμε την δυνητική επικρατούσα καθώς και την υφιστάμενη βλάστηση ανά όροφο βλάστησης. Παράλληλα σχολιάζουμε την φυτοδυναμική πορεία της βλάστησης κάτω από τη δράση των όποιων αρνητικών επεμβάσεων που ασκούνται στην περιοχή έρευνας. Διερευνήθηκαν οι κυριότερες επεμβάσεις και οι επιπτώσεις αυτών στα οικοσυστήματα της περιοχής έρευνας. Μεταξύ αυτών περιλαμβάνονται η παρουσία μεταλλείων βωξίτη, οι εκτεταμένες διανοίξεις δασικών δρόμων, οι πυρκαγιές, η βόσκηση, οι εκχερσώσεις, η παράνομη λειτουργία ανεξέλεγκτων χώρων διάθεσης απορριμμάτων κλπ. Αξιολογήθηκαν 77 taxa τα οποία κρίθηκαν ότι εμφανίζουν σημαντικό ενδιαφέρον, είτε λόγω του περιορισμένου αριθμού και των σημαντικών κινδύνων που αυτά διατρέχουν, είτε για την ιδιαίτερη φυτογεωγραφική σημασία που κάποια από αυτά εμφανίζουν. Σε γενικές γραμμές η περιοχή έρευνας εμφανίζει εξαιρετική έως μεγάλη αξία για την διατήρηση ενός μεγάλου αριθμού από τα παραπάνω είδη. Από την αξιολόγηση 15 τύπων οικοτόπων, που εμφανίζονται στην περιοχή μας προέκυψαν τα ακόλουθα: Υψηλό βαθμό συνολικής αξιολόγησης έλαβαν τα ευμεσογεικά βράχια και τα βραχώδη πρανή των υψηλών κορυφών. Ακολουθούν τα δάση φυλλοβόλων δρυών και Κεφαλληνιακής Ελάτης, ενώ ικανοποιητική σημασία έχουν οι μονάδες βλάστησης του ανωδασικού χώρου, οι πρινώνες, τα δάση αριάς, καθώς και αυτά της ελιάς και χαρουπιάς. Παράλληλα προχωρήσαμε και στην αξιολόγηση της περιοχής στο σύνολο της, χρησιμοποιώντας τόσο εδώ όσο και στις αξιολογήσεις φυτικών ειδών και οικοτόπων μια σειρά ευρέων αποδεκτών κριτηρίων. Τέλος επισημαίνονται οι κυριότερες διαχειριστικές δράσεις που αποβλέπουν στη διατήρηση και προστασία των φυσικών οικοσυστημάτων αλλά και στην ανάδειξη της περιοχής. / The mountains Elikonas, Xerovouni ands Neraidolakkoma are situated in the south-central part of Sterea Ellada Department. In the present thesis we examine the information concerning the abiotic environment, such as the topography, the geology, the climate and the bioclimate. The flora of the study area consists of 1273 taxa, out of which 116 are Greek and 72 Balkan endemics. In the framework of the doctoral thesis we analyze the life form spectrum and the chorological spectrum of our flora. Moreover, we look into the plant geographical relations of the mountainous complex with other regions in Greece as well as with the main mountains of Sterea Ellada and of Peloponnese. The phytosociological research resulted to the distinction of 20 associations and 17 communities. Among them, 3 new associations and 6 new communities are described. Furthermore, elements of ecological succession of the vegetation units are juxtaposed, as well as the most critical human threats. Finally, we evaluate a significant number of vegetal elements, the habitats under observation, but also the research area in its total.

The plants of San Quintín (Baja California, Mexico) were documented through intensive fieldwork and the collection of herbarium specimens to create a checklist of species. This region is home to a diverse flora with high levels of local endemism and many rare plants. The flora documented in this study was compared to historical records from the region and shows the impact of agriculture and urbanization on the plants, including several extirpated species. A study of the perennial vegetation using a 1 km grid provides species distribution data for 140 native species, which were assessed to highlight areas of significant species richness for native, rare, and endemic taxa. Several non-native plants were also mapped to provide baseline data. Areas of conservation priority for the flora of Greater San Quintín are discussed in light of these combined findings.
