Its main goal is to see fragmentation of writing as an aesthetic resource highlighted in the work of Tutam?ia by Guimar?es Rosa (1908-1967), and in Livro sobre nada by Manoel de Barros (1916). We undertake as a starting point the view that these works are allegorical expressions. We have as a basis the German philosopher Walter Benjamin (1984) conception about baroque allegory, that uses amorphous fragment and constitutes a dialectical expression, in which each person, each thing, each relation, may mean any other one (1984, p. 196). We see the stylistic features as used by Guimar?es Rosa and by Manoel de Barros in the construction of poetics capable of breaking the boundaries between artistic genres, literary and discursive, adding oral, musical and plastic elements to writing. We also analyze the development of fragmentary poetics, in which the voice of the narrator/lyrical I, the characters, space, plot and time exhibit the fragment as a factor that contributes to the great ambiguity of the two works and to create a new language, performative and vibrant, rich in alluring images, allegories / O presente estudo est? vinculado ? linha de pesquisa Po?ticas da Modernidade e da P?s-Modernidade, do Programa de P?s-Gradua??o em Estudos da Linguagem, na ?rea de Literatura Comparada - CCHLA/UFRN. Seu objetivo principal ? observar a fragmenta??o da escritura como recurso est?tico privilegiado em Tutam?ia, de Guimar?es Rosa (1908-1967), e no Livro sobre nada, de Manoel de Barros (1916). Na pesquisa, adotamos como ponto de partida a vis?o de que essas obras s?o express?es aleg?ricas. Tomamos como base a concep??o do fil?sofo alem?o Walter Benjamin (1984) sobre a alegoria barroca, a qual se vale do fragmento amorfo e se constitui numa express?o dial?tica, em que cada pessoa, cada coisa, cada rela??o, pode significar qualquer outra (1984, p. 196). Observamos os recursos estil?sticos usados tanto por Guimar?es Rosa quanto por Manoel de Barros na constru??o de po?ticas capazes de romper com os limites entre os g?neros art?sticos, liter?rios e discursivos, agregando ? escrita elementos orais, musicais e pl?sticos. Analisamos ainda a elabora??o de po?ticas fragment?rias, em que a voz do narrador/eu-l?rico, as personagens, o espa?o, o enredo e o tempo exibem o fragmento como elemento que contribui para a grande ambiguidade das duas obras e para a cria??o de uma linguagem nova, perform?tica e vibrante, rica em sedutoras imagens, alegorias

Tem como um dos seus principais sintomas a cria??o de dist?ncias f?sicas e simb?licas. Especificamente, esse fen?meno muito se relaciona ? crescente polariza??o entre o mundo p?blico e privado, que culmina na quebra da conex?o f?sica e simb?lica desses dois mundos. As cidades tamb?m apresentam velhos sintomas da autossegrega??o das camadas m?dias, muitas vezes associados aos chamados condom?nios fechados. Esses espa?os s?o oferecem fortifica??o e prote??o dos ?infort?nios? da cidade, bem como asseguram uma aparente qualidade de vida. O presente trabalho procura analisar, considerando a conex?o entre o local e o global, como um condom?nio fechado contribui para o fen?meno da fragmenta??o urbana, com base no estudo de caso do Condom?nio Jardim Atl?ntico, localizado na zona de conurba??o entre Natal/RN e Parnamirim/RN. Para considerar o global e o local, realiza a pesquisa aos moldes etnogr?ficos, especificamente a observa??o direta associada ? an?lise documental, e entrevistas qualitativas, associando sua totalidade ? din?mica da cidade. O estudo conclui que a din?mica interna do condom?nio junto ? din?mica da cidade exerce influ?ncia nas representa??es de seus moradores, o que acaba acentuado a distin??o entre o mundo p?blico e privado desses indiv?duos. Para eles, a cidade ? repleta de ilhotas organizadas de forma peculiar frente ao objeto p?blico, as quais s?o transit?veis por meio de seus ve?culos. Esses deslocamentos, junto ao desejo de se chegar a uma ilhota, formam verdadeiros hiatos que exprimem a nega??o da cidade. / The urban fragmentation is a recent phenomenon that spreads over the world. It has as the main characteristic physical and symbolical distances. Specifically, this phenomenon is related to the polarization that is growing between public and private world, resulting in the broken of physical and symbolical connection of those worlds. Cities also present old symptoms of media classes? self-segregation, many times associated to the closed condominiums. Those habitations give protection and strengthens from the ?treat? of the city, as well as they assure an apparent quality of life. This study aims to analyze, considering connection between local and global, how a closed condominium contributes to the phenomenon of urban fragmentation, based on case study of Jardim Atl?ntico condominium, situated between Natal and Parnamirim/RN. To consider global and local, it is an ethnographic research, specifically direct observation associated to the documental analyze, and qualitative interview related to the city dynamics. It concludes that condominium intern dynamic linked to the city dynamic have influence in the resident representations, that detaches differences between public and private world of those people. To them, the city is full of organized little islands in a peculiar way to the public object, made to pass through by their cars. Those routes connected to the desire to go to the little island are the real gaps that expresses city negation.

Since the ability to perceive and react to specific conditions varies greatly between organisms, different movement patterns are generated. These, in turn, will reflect the way species persist in the original habitat and surrounding patches. This study evaluated patterns of movement of frugivorous butterflies in order to estimate the connectivity of a landscape mosaic in an area of Atlantic Forest. For this purpose, we used the capture-mark-recapture method on butterflies trapped with fermented fruit bait in three distinct habitats. The first represents a typical Atlantic forest fragment, while the other two represent man-made matrix habitats. One contains a coconut plantation and the other a plantation of the exotic Acacia mangium species. Five traps were randomly placed in each landscape unit in areas of 40 x 40m. Using recapture data and relating it to distance between captures and habitat structure, I found that movement frequencies, both within and between landscape units were different for the analyzed species, suggesting that they do not interpret and react to the landscape in the same way. Thus this study was able to measure landscape functional connectivity. For most species, the exchange between forest and coconut plantations occurred with low frequency compared to exchanges between the forest and acacia plantations, which share more structural similarities. This seems to indicate that a matrix that is more similar to patches of native vegetation can shelter species, permit their movement and, consequently, contribute to the landscape connectivity / O movimento de organismos dentro e entre unidades de habitat ? um tra?o essencial da hist?ria de vida que molda a din?mica das popula??es, comunidades e ecossistemas no espa?o e no tempo. Como a habilidade de perceber e reagir ?s condi??es espec?ficas de habitat varia grandemente entre os organismos, diferentes padr?es de movimento s?o gerados. Estes, por sua vez, v?o refletir na forma com que esp?cies persistem nos remanescentes de habitat original e de entorno. Este estudo avaliou padr?es de movimento de borboletas frug?voras para estimar a conectividade em um mosaico paisag?stico em uma ?rea de Mata Atl?ntica. Para tal foi utilizado o m?todo de Captura-Marca??o-Recaptura de borboletas, utilizando armadilhas com iscas de fruta fermentada, em tr?s tipos de habitats. O primeiro, mata, representa as condi??es normais de um remanescente de Mata Atl?ntica, ao passo que os outros dois representam matrizes antropog?nicas, contendo planta??o de coqueiro em uma delas e planta??o de uma ?rvore ex?tica (Acacia mangium). Cinco armadilhas foram aleatoriamente colocadas em cada unidade da paisagem em ?reas de 40 x 40m. Usando dados de frequ?ncia de captura de borboletas e relacionando com dados de dist?ncia entre armadilhas e estrutura dos habitats, encontrei que as frequ?ncias de movimento, tanto dentro quanto entre unidades da paisagem s?o diferentes para as esp?cies analisadas, indicando que as mesmas n?o parecem sentir e reagir ? paisagem da mesma maneira. Assim, este estudo conseguiu medir conectividade funcional na paisagem. Para a maioria das esp?cies, as trocas entre mata e coqueiral ocorreram com baixa frequ?ncia, em compara??o ?s trocas entre mata e ac?cia, que compartilham mais semelhan?as estruturais. Os resultados sugerem que uma matriz mais similar a manchas de vegeta??o nativa pode abrigar esp?cies, ser perme?vel ao movimento e, consequentemente, contribuir para conectividade da paisagem

A tend?ncia ao maior crescimento demogr?fico nas ?reas periurbanas em expans?o ocasionou novas formas da produ??o do espa?o. A ?vida procura por solo apto a implanta??o de moradias pelo mercado imobili?rio, est? consolidando processos anteriores e gerando novas variantes na ocupa??o dos tecidos metropolitanos.

O territ?rio metropolitano foi analisado em duas escalas: a intraurbana, constitu?da pelos munic?pios de Natal, Parnamirim e S?o Gon?alo do Amarante, enquadrados nesta pesquisa como ?rea Metropolitana Funcional; a interurbana, levando em considera??o todos os munic?pios da RMN. Ambas as escalas foram analisadas buscando os momentos e condi??es gerais que ao longo da hist?ria do processo de metropoliza??o da RMN constitu?das por interven??es por parte do Estado e do mercado imobili?rio, que delinearam a fragmenta??o dos tecidos urbanos e as desigualdades socioespaciais por meio do processo que aqui est? sendo denominado por ?Urbaniza??o Imobili?ria Residencial?. / In the last decades the Natal Metropolitan Area (NMR), as well as in much of Brazil, experienced a population and spatial growth in its cities through/experiencing an urban sprawl pattern of expansion. The trend to intensive growth in peri-urban areas led to new forms of production of space. The real estate search for available land for housing production, are consolidating old processes and generating new patterns in the metropolitan land fabric. This leads us to question: how is the result of the residential real estate dynamic in the (re) configuration of the NMR? What forms and territorial phenomena are evident in this spatial process of the metro area? How much the Minha Casa Minha Vida (MCMV) housing politic is responsible for the spatial changes of NMR? This research aims to understand the logic and the urban sprawl process analyzing/through the recent production of social housing, contributing with an explanatory model of spatial configuration of the NMR. The metro area was analyzed on two scales: the urban, including Natal, Parnamirim and S?o Gon?alo do Amarante cities, framed in this research as Functional Metropolitan Area; intercities, taking into consideration all the municipalities of NMR. In both scales there were cronologically observed the general conditions of the NMR metro expansion throught the state and the real estate interventions, that resulted into the fragmentation of the urban fabric and socio-spatial inequalities what we called here as ?Urbaniza??o Imobili?ria Residencial?.

O bioma Caatinga, um ecossistema semi?rido espalhado por 826.000 km2 do territ?rio brasileiro, apesar de estar altamente fragmentado, ainda mant?m metade da sua cobertura vegetal original. Os remanescentes, no entanto, t?m sido perturbando h? s?culos por uma multiplicidade de amea?as antropog?nicas, incluindo sobrepastejo, extra??o madeireira, fogo e ca?a, entre outro. Apesar disto, a ?rea sobre prote??o est? abaixo do proposto por acordos internacionais e projetos de restaura??o t?m sido escassos. Baseado em m?ltiplas an?lises espacialmente explicitas, os quatro cap?tulos desta Tese tiveram como principais objetivos: (1) analisar quantitativamente a estrutura de fragmenta??o da Caatinga, (2) estimar o n?vel de perturba??o antr?pica cr?nica potencial dos fragmentos da Caatinga, (3) identificar as ?reas priorit?rias de restaura??o da Caatinga, baseado em conectividade da paisagem e na riqueza de esp?cies de plantas amea?adas e (4) comparar a perda de habitat e a taxa de desmatamento das ?reas Priorit?rias de Conserva??o da Caatinga, definidas pelo Minist?rio do Meio Ambiente (MMA), com as ?reas Priorit?rias dos outros biomas brasileiros. An?lises de Sistemas de Informa??o Geogr?fica, executadas sobre informa??es oficiais dispon?veis, evidenciam boas e m?s not?cias para o bioma. Apesar da fragmenta??o j? sofrida pelo bioma, o n?vel de conectividade funcional permanece relativamente alta entre fragmentos e metade da vegeta??o remanescente est? preservada em fragmentos grandes (? 50.000 ha), indicando a exist?ncia de preciosas oportunidades de conserva??o pr?-ativas. Em contraste, o n?vel de fragmenta??o ? intenso e 90% da vegeta??o remanescente ocorre em dist?ncias menores que 2,5 km da borda florestal, permitindo um f?cil acesso ao j? escasso habitat interior. Um ?ndice de Perturba??o Antr?pica Cr?nica (IPC), que sintetiza o efeito de perturba??o potencial de 14 vari?veis prim?rias, indicam que todos os fragmentos de Caatinga est?o sob algum n?vel de perturba??o. No entanto, uma importante heterogeneidade regional foi detectada, com fragmentos mais perturbados ocorrendo nas por??es norte, leste e central do bioma. Apesar do IPC m?dio dos fragmentos n?o estar correlacionado com a sua ?rea, o IPC declina n?o linearmente com a dist?ncia de borda mostrando ?reas relativamente est?veis ap?s 5 km. Simula??es de paisagens, testando a import?ncia de cada bacia hidrogr?fica para a conectividade da paisagem, permitiram a identifica??o de importantes ?reas para restaura??o. Cruzando este crit?rio com o n?mero de esp?cies de plantas amea?adas, foi poss?vel identificar um subconjunto de paisagens chaves para restaura??o que compreendem apenas 8% da ?rea desmatada do bioma. Estimando a taxa de desmatamento de todas as ?reas Priorit?rias para Conserva??o dos biomas terrestres brasileiros, foi poss?vel demonstrar que a Caatinga e o Cerrado exibiram as maiores taxas de perda de habitat, demonstrando novamente a vulnerabilidade do bioma. Espera-se que as informa??es aqui disponibilizadas possam ajudar tomadores de decis?o, nacionais e estaduais, a avan?ar pol?ticas para a conserva??o, restaura??o e manejo da biodiversidade. / Reliable landscape information at large spatial scale is essential for decision makers dealing with biodiversity conservation, ecosystem restoration, resource management, and environmental policy. The Caatiga biome, a semiarid ecosystem that spreads over 826,000 km2 of the Brazilian territory, despite being highly fragmented, still holds half of its original vegetation cover. The remnants, however, have been disturbed for centuries by a multitude of different anthropogenic threats, including overgrazing, logging, fire, hunting, among others. Despite that, the area under protection is below international agreements and restoration endeavors have been scarce. Based on a multitude of spatially explicit analyses, the four chapters of this Thesis had as main objectives: (1) to analyse quantitatively the fragmentation structure of the Caatinga biome, (2) to estimate the level of potencial cronic anthropogenic disturbance of the Caatinga fragments, (3) to identify the priority areas for restoration in the Caatinga biome, based on landscape connectivity and number of endangered plant species, and (4) to compare habitat loss and deforestation rates of Conservation Priority Areas of the Caatinga, defined by the Ministery of Environment (MMA), with those in other Brazilian biomes. Geographic Information System analyses, performed on officially available information, show both good and bad news for the biome. Despite the fragmentation already experienced by the biome, the level of functional connectivity remains relatively high among fragments and half the remaining vegetation is preserved in large fragments (? 50,000 ha), indicating the existence of precious pro-active conservation opportunities. In contrast, the fragmentation level is intense and 90% of the remaining vegetation occurs at distances lower than 2.5 km from the forest edge, allowing an easy access to the already scarce Caatinga core area. An Index of Chronic Anthropogenic Disturbance (IPC), which synthesizes the potential perturbation effect of 14 primary variables, indicates that all Caatinga fragments are under some degree of perturbation. However, important regional heterogeneity was detected with more disturbed fragments occurring in the Northern, Eastern, and Central regional of the biome. Although the mean IPC of the fragments is not correlated to its area, IPC drops non-linearly with edge distance, showing relatively stable core areas after 5 km. Landscape simulations, testing the importance of each watershed for landscape connectivity, allowed the identification of relevant areas for restoration. By crossing this criterion with the number of endangered plant species in each watershed, we were able to identify a subset of key watersheds for restoration that hold only 8% of the deforested area of the biome. By estimating the deforestation rate of all Priority Areas for Conservation of the Brazilian terrestrial biomes, it was possible to demonstrate that the Caatinga and the Cerrado biomes exhibited the higher rates of habitat loss, further demonstrating the vulnerability of the biome. Hopefully, the information here provided can help national and state decision makers to advance biodiversity policies for biodiversity conservation, restoration, and management.

Dissertation (Master of Science in Animal Biology). Instituto de Biologia, Departamento de Biologia Animal, Universidade Federal Rural do Rio de Janeiro, Serop?dica, RJ, 2011. A data set containing a list of the known species of frogs that occur near shore and on eight islands of the south coast of the State of Rio de Janeiro and north of the State of S?o Paulo was produced. For that, I compiled data from the literature and conducted inventories of a few of the islands. This list included 67 anuran species belonging to 11 families for eight islands and 117 species and 14 families for two localities on the mainland. The pattern of richness between islands was analyzed in respect to the island area and the composition of habitats used by the anurans for reproduction. Insular structural complexity was also evaluated in this regard. The results of correlation analyses of area vs. species richness and species richness vs. number of reproductive habitats were highly significant indicating that species richness prediction in fragmented environments depends on both factors. Nestedness analyses using the metric NODF was performed in an attempt to investigate whether shared species absences among the islands are the result of a random process or represents a pattern indicative of ordered loss of species. The predicted pattern was confirmed ? that is, that species loss is nonrandom and that this was possibly caused by habitat loss. The role played by climatic events at the beginning of the Holocene and of the availability of reproductive habitats in the islands upon species loss is discussed. Furthermore, it is discussed how these results can help to guide conservation strategies of anuran species. / BITTENCOURT-SILVA, Gabriela Bueno.

This research investigates the existing conditions of the present urban settings, in particular some city clippings, focusing on urban dynamics found in the open spaces system (SEL), alongside with the process of use and occupation of the urban land and its possible socio environmental impacts. To develop this work clippings were chosen in different contexts of formation of the territory as well as a diverse socioeconomic and cultural reality, each one presenting its own urban growth milestone which characterized by: a) the peripheral zone composed by industries and low-income population; b) by the installation of large scale commercial initiatives and c) housing demand of high standard - Residencial Cosmos/Jardim Florence I, Parque Dom Pedro Shopping e Alphaville I (Rod. Campinas ? Mogi-Mirim) respectively. Using the urban morphology as a reading method of these process and the open spaces system (SEL) as protagonist of analysis, was adopted as a research method a study of the history and urban growth for each crop selected identifying: a) the different agents involved; b) management plans; c) socioeconomic and cultural contexts and d) the functional, aesthetic and environmental aspects of public and private open spaces. As a result it was possible to identify dialectical processes in the formation of the urban landscape identifying in the different morphological types their potential, barriers and conflicts. / O crescimento de Campinas entre o final do s?culo XX e o in?cio do XXI, esteve apoiado na forma??o de tecidos urbanos fragmentados, distantes e mal conectados entre si e da regi?o central.

Ibuprofen is a nonsteroidal antiinflammatory or broadband use in the clinic. Once in the bloodstream, most of ibuprofen is linked to human serum albumin, the major protein of blood plasma, decreasing its bioavailability and requiring larger doses to produce its antiinflamatory action. This study aimes to characterize, through the interaction energy, how is the binding of ibuprofen to albumin and to establish what are the main amino acids and molecular interactions involved in the process. For this purpouse, it was conducted an in silico study, by using quantum mechanical calculations based on Density Functional Theory (DFT), with Generalized Gradient approximation (GGA) to describe the effects of exchange and correlation. The interaction energy of each amino acid belonging to the binding site to the ligand was calculated the using the method of molecular fragmentation with conjugated caps (MFCC). Besides energy, we calculated the distances, types of molecular interactions and atomic groups involved. The theoretical models used were satisfactory and show a more accurate description when the dielectric constant ε = 40 was used. The findings corroborate the literature in which the Sudlow site I (I-FA3) is the primary binding site and the site I-FA6 as secondary site. However, it differs in identifying the most important amino acids, which by interaction energy, in order of decreasing energy, are: Arg410, Lys414, Ser 489, Leu453 and Tyr411 to the I-Site FA3 and Leu481, Ser480, Lys351, Val482 and Arg209 to the site I-FA6. The quantification of interaction energy and description of the most important amino acids opens new avenues for studies aiming at manipulating the structure of ibuprofen, in order to decrease its interaction with albumin, and consequently increase its distribution / Na atualidade, os m?todos computacionais v?m sendo cada vez mais utilizados para auxiliar a biologia molecular na caracteriza??o de sistemas biol?gicos, principalmente quando esses possuem relev?ncia para a sa?de humana. O ibuprofeno ? um antiinflamat?rio n?o-esteroidal de larga utiliza??o na cl?nica. Uma vez na corrente sangu?nea, boa parte do ibuprofeno fica ligada a albumina de soro humano, a principal prote?na do plasma sangu?neo, diminuindo a sua biodisponibilidade e necessitando de maiores doses para a produ??o de seu efeito antiinflamat?rio. Este estudo teve por objetivo caracterizar, atrav?s da energia de intera??o, como ocorre a liga??o do ibuprofeno ? albumina e estabelecer quais os principais amino?cidos e intera??es moleculares envolvidas no processo. Para tal desenvolveu-se um estudo in silico, com utiliza??o de c?lculos de mec?nica qu?ntica, baseada na Teoria do Funcional da Densidade (DFT), com aproxima??es do Gradiente Generalizado (GGA) para descri??o dos efeitos de correla??o e troca. A energia de intera??o de cada amino?cido do s?tio de liga??o, com o ligante foi calculada com base no m?todo de fragmenta??o molecular com capas conjugadas (MFCC). Al?m da energia, foram calculadas as dist?ncias, tipos de intera??es moleculares e grupos at?micos envolvidos. Os modelos te?ricos utilizados foram satisfat?rios e demonstraram uma descri??o mais precisa com a utiliza??o da constante diel?trica ε=40. Os achados corroboram com a literatura colocando o s?tio Sudlow I (I-FA3) como o principal s?tio de liga??o e o s?tio I-FA6 como s?tio secund?rio. Contudo, difere quanto ? identifica??o dos amino?cidos mais importantes, que por meio da energia de intera??o, em ordem decrescente de energia, s?o: Arg410, Lys414, Ser 489, Leu453 e Tyr411 para o S?tio I-FA3 e Leu481, Ser480, Lys351, Val482 e Arg209 para o s?tio I-FA6. A quantifica??o da energia de intera??o e a descri??o dos amino?cidos mais importantes abre caminhos para novos estudos que visem a manipula??o da estrutura do ibuprofeno, no sentido de diminuir a intera??o desse com a albumina, e consequentemente aumentar a sua distribui??o

Pesquisa do Estado da Bahia - FAPEB / (Effect of edge in structure, diversity and phenology in seasonal tropical forest submontane) Forest fragmentation causes physical and biological changes with habitat loss and insularization of populations, and the edge effect the most obvious consequence of this process. Thus, this study aimed to investigate the effect of linear edge in a fragment of submontane seasonal forest in the Chapada Diamantina, Bahia, Brazil (12?28'31 "S and 41?23'14''W) in order to analyze the structure and composition vegetation, reproductive phenology and the vegetative phenology, classifying the forest as their leaf pattern, and the functional diversity. Were marked 30 plots (10 x 10 m) random and 15 at the forest edge (0 - 100m) and 15 inside (> 150m) in the power line high voltage. For structural studies were marked all individuals with diameter at breast height ?5 cm. The species were classified according to successional category and phytosociological parameters were calculated and diversity indices. The Shannon - Wiener index was compared by t test Hutcheson and the other parameters by ANOVA. From this study the species with the highest importance value and abundance for the other investigations were chosen. In the reproductive phenological study monthly observations were made over 26 months in 481 individuals (282 on the edge (61 species) and 199 inside (50 species) of forest), recording the presence and absence of flowering (and flower button) and fruiting (immature and mature fruit) for all life forms. It is estimated timing, frequency and duration of phenological events and the species were classified as the pollination and dispersal syndromes. Data were analyzed with G test, linear regression and circular statistics. In the study of functional diversity created a matrix of functional traits to the edge and interior including phenological, structural and reproductive aspects. Measurements of leaf traits (thickness, dry dough sheet per unit area, juiciness, density, leaf area ratio and leaf mass fraction), density and wood water saturation were carried out in the dry and wet seasons (September / 2012 and January / 2013) in 20 species. Regressions were made between phenophases and environmental variables (precipitation, temperature, relative humidity, photoperiod and heat stroke), circular statistics and comparisons of leaf traits and wood density between the dry and rainy season through the G test and ANOVA. The species ordination in relation to leaf and wood attributes was evaluated by Principal Component Analysis (PCA). The functional groups were defined by cluster analysis with distance Gower and calculated indexes Functional richness (FRic), Functional divergence (FDiv), Functional evenness (FEve), Functional dispersion (FDis). ANOVA and linear regression were used to evaluate the rates between areas. In vegetative phenological study followed up the budding and leaf fall 350 individual trees in the community (39 species). Increase the impact of straight edge on the floristic composition was checked, the diversity and abundance of species, while less interference was observed in the tree community structure, as phytosociological parameters and ratios between the guilds did not differ significantly between edge and interior fragment. The phenological analysis revealed that flowering and fruiting at the edge and interior were continued for long, low-intensity periods, asynchronous and assazonal being for most phenophases, with a significant difference in the individual to button number. Seasonality in flowering and fruiting were observed for bush and grass land in both areas and epiphytes to the edge. Similar proportions in the number of species for pollination and dispersal syndromes were found on the edge and inside, with a predominance of melittophilous and animal dispersed species. The vegetation was evergreen, with budding and continuous leaf fall, low intensity and low sync. The leaf bud was related to rainfall and sunshine and fall with precipitation and humidity. Significant variation between the dry and wet seasons were observed in the proportion of saturated water in the wood, leaf area ratio and leaf succulence. ACP showed greater variance for wood density (88.7%) and stored water (11.3%), gathering most species with standard perenif?lios phenological and episodic perenif?lios, other attributes showed no relevance to the phenological patterns. The main functional groups formed on the edge and inside were similar, defined based on the way of life, stratum and pollination and dispersal. Of co-occurring species (40 species), 22.5% belong to different functional groups due to different growth patterns. The functional diversity indices showed higher mean values for the edge, except that Fric was higher in the forest. These were not affected by the distance to the edge. Changes were observed inside in relation to species richness and Shannon - Wiener only for Fric. The implementation of linear infrastructure brings similar impacts to those coming from other types of edges in community structure. In other aspects analyzed the changes were subtle for the tree community, but the same was not true for shrubs, herbs and vines. The vegetation can be classified as seasonal submontane rainforest always green, with small annual variation in the physiognomy of the vegetation, and the perenif?lios and perenif?lios types episodic predominant both in number of species and in their abundance. The leaf traits showed no relevance to phenology, not being good descriptors for the seasonal evergreen forest. There is no significant difference in functional diversity, but the highest rate obtained inside for functional wealth reflects the biological loss caused by the installation on the edge of the linear edge. Appearance evidenced by the greater abundance of Eschweilera tetrapetala Mori inside, an endemic species of submontane forests of the region. This study contributes to future conservation work to note the interference the linear edge on the forest ecosystem, as well as to the classification of the Brazilian forests, to verify the occurrence of seasonal evergreen forests in the Caatinga. / (Efeito de borda na estrutura, diversidade e fenologia de floresta tropical estacional submontana) A fragmenta??o florestal causa mudan?as f?sicas e biol?gicas com perda de habitat e insulariza??o das popula??es, sendo oefeito de borda a consequ?ncia mais evidente desse processo.Assim,objetivou-se investigar o efeito da borda linear em um fragmento de floresta estacional submontana na Chapada Diamantina, Bahia,Brasil (12?28?31??S e 41?23?14??W) com o intuito de analisar a estruturae a composi??o da vegeta??o, a fenologia reprodutivae a fenologia vegetativa, classificando a floresta quanto ao seu padr?o foliar, e a diversidade funcional. Foram marcadas 30 parcelas (10 x 10 m) aleat?rias sendo 15 na borda da floresta (0 - 100m) e 15 no seu interior (>150m) em rela??o ? rede el?trica de alta tens?o. Para o estudo estrutural foram marcados todos os indiv?duos com di?metro ? altura do peito ?5 cm. As esp?cies foram classificadas quanto ? categoria sucessional e foram calculados os par?metros fitossociol?gicos e ?ndices de diversidade. O ?ndice de Shannon - Wienerfoi comparado pelo teste t de Hutcheson e os demais par?metros pela ANOVA. A partir desse estudo foram escolhidas as esp?cies com maior valor de import?ncia e abundancia para as demais investiga??es.No estudo fenol?gico reprodutivo foram realizadas observa??es mensais durante 26 meses a 481 indiv?duos (282 na borda (61 esp?cies) e 199 no interior (50 esp?cies) da floresta), registrando-se a presen?a e aus?ncia de flora??o (bot?o e flor) e frutifica??o (frutos imaturo e maturo) para todas as formas de vida. Estimou-se sincronia, frequ?ncia e dura??o dos eventos fenol?gicos e as esp?cies foram classificadas quanto ?s s?ndromes de poliniza??o e dispers?o. Os dados foram analisados com teste G, regress?o linear e estat?stica circular. No estudo da diversidade funcional criou-se uma matriz de tra?os funcionais para a borda e interior incluindo aspectos fenol?gicos, estruturais e reprodutivos.Mensura??es de atributos foliares (espessura, massa seca de folha por unidade de ?rea, sucul?ncia, densidade, raz?o de ?rea foliar e fra??o de massa foliar), densidade e ?gua de satura??o da madeira foram realizadas nas esta??es seca e chuvosa (setembro/2012 e janeiro/2013) em 20 esp?cies. Foram feitas regress?es entre as fenofases e as vari?veis ambientais (precipita??o, temperatura, umidade relativa, fotoper?odo e insola??o), estat?stica circular e compara??es dos atributos foliares e densidade de madeira entre a esta??o seca e chuvosa atrav?s do teste G e ANOVA. A ordena??o das esp?cies em rela??o aos atributos foliares e de madeira foi avaliada pela An?lise do Componente Principal (ACP). Os grupos funcionais foram definidos por Cluster analysis com dist?ncia de Gower e calculados os ?ndices Functional richness (FRic), Functional divergence (FDiv), Functional evenness (FEve), Functional dispersion (FDis). ANOVA e regress?o linear foram usadas para avaliar os ?ndices entre ?reas. No estudo fenol?gico vegetativo acompanhou-se o brotamento e queda foliar de 350 indiv?duos arb?reos na comunidade (39 esp?cies). Foi verificado um maior impacto da borda linear sobre a composi??o flor?stica,a diversidade e abund?ncia das esp?cies, enquanto menor interfer?ncia foi verificada na estrutura da comunidade arb?rea, uma vez que par?metros fitossociol?gicos e propor??es entre as categorias sucessionais n?o diferiram significativamente entre borda e interior do fragmento.As an?lises fenol?gicas revelaram que a flora??o e frutifica??o na borda e interior foram cont?nuas por per?odos longos e com baixa intensidade, sendo assincr?nico e assazonal para a maioria das fenofases, com diferen?a significativa no n?mero de indiv?duo para bot?o.Sazonalidade na flora??o e frutifica??o foi observada para arbusto e erva terrestre em ambas as ?reas e ep?fitas para a borda.Propor??es semelhantes no n?mero de esp?cies por s?ndromes de poliniza??o e dispers?o foram encontradas na borda e no interior, com predomin?ncia de esp?cies melit?filas e zooc?ricas.A vegeta??o foi perenif?lia, com brotamento e queda foliar cont?nuos, baixa intensidade e baixa sincronia. O brotamento foliar relacionou-se com precipita??o e insola??o e a queda com precipita??o e umidade. Varia??o significativa entre as esta??es seca e chuvosa foram observadas na propor??o de ?gua saturada na madeira, raz?o de ?rea foliar e sucul?ncia da folha. ACP revelou maior varian?a para densidade da madeira (88,7%) e ?gua armazenada (11,3%), agrupando a maioria das esp?cies com padr?o fenol?gico perenif?lios e perenif?lios epis?dicos, os demais atributos n?o apresentaram relev?ncia em rela??o aos padr?es fenol?gicos. Os principais grupos funcionais formados na borda e no interior foram semelhantes, definidos com base na forma de vida, estrato e s?ndrome de poliniza??o e dispers?o. Das esp?cies co-ocorrentes (40 esp?cies), 22,5% pertencem a grupos funcionais distintos devido a diferentes padr?es fenol?gicos. Os ?ndices de diversidade funcional apresentaram valores m?dios superiores para a borda, exceto FRic que foi superior no interior da floresta. Estes n?o foram alterados pela dist?ncia com a borda. Altera??es foram observadas no interior em rela??o ? riqueza de esp?cie e ao ?ndice de Shannon - Wiener apenas para FRic.A implementa??o de infraestruturas lineares traz impactos semelhantes ?queles advindos de outros tipos de bordas na estrutura da comunidade. Nos demais aspectos analisados as varia??es foram sutis para a comunidade arb?rea, mas o mesmo n?o ocorreuem rela??o a arbustos, ervas e trepadeiras. A vegeta??o p?de ser classificada como floresta tropical estacional submontana sempre verde, com pequena varia??o anual na fisionomia da vegeta??o, sendo os tipos perenif?lios e perenif?lios epis?dicos predominantes tanto em n?mero de esp?cies quanto na sua abund?ncia. Os atributos foliares n?o apresentaram relev?ncia em rela??o aos padr?es fenol?gicos, n?o sendo bons descritores para a floresta estacional sempre verde. N?o h? diferen?a significativa na diversidade funcional, mas o maior ?ndice obtido no interior para a riqueza funcional reflete a perda biol?gica ocasionada na borda pela instala??o da borda linear.Aspecto evidenciado pela maior abund?ncia deEschweilera tetrapetala Mori no interior, esp?cie end?mica das florestas submontanas da regi?o. O presente estudo p?de contribuir com futuros trabalhos de conserva??o por constatar a interfer?ncia da borda linear no ecossistema florestal, bem como com a classifica??o das florestas brasileiras, ao verificar a ocorr?ncia de florestas estacional sempre verde no Bioma Caatinga.
