Initially, a study was done to optimize the synthesis of Al-SBA-15. Through this study, it was found that the operating conditions that resulted in the SBA-15 sample with a higher degree of ordering were gel aging time equal to 15 hours at 40 ? C and then at 100 ? C for 8 hours. These optimal conditions were used to perform scaling up to 5 gallon reactor. Samples of Al-SBA-15 were subjected to carbonization in order to fill the pores of SBA-15 with carbonaceous material and prevent the collapse of its structure. The carbonized samples were used as a source of silica for the synthesis of mordenite in dry medium using the transmission technique in the vapor phase (VPT). The purpose of this procedure was to obtain the mordenite having mesopores. For the preparation of the mordenite by VPT, several conditions were used, varying the synthesis time and form of addition of the reactants, presence or absence of an organic driver. The samples were characterized by X-ray and nitrogen adsorption. It was observed that in most of the experiments, there was no formation of mordenite phase. In the experiments in this phase was obtained, there was no significant mesoporosity training. Apparently, the presence of carbonaceous material was not sufficient to preserve the mesoporous structure of SBA-15. Key / No presente trabalho foi realizado o estudo da s?ntese da peneira molecular mesoporosa Al-SBA-15 a partir da s?ntese direta em reator agitado apresentando a seguinte propor??o molar: 14 SiO2: 1 Al2O3: 0,235 P123: 1800 H2O. Inicialmente, foi feito um estudo visando otimizar a s?ntese da Al-SBA-15. Atrav?s deste estudo, foi verificado que as condi??es operacionais que resultaram na amostra de SBA-15 com maior grau de ordenamento foram com tempo de envelhecimento do gel de s?ntese igual a 15 horas a 40?C e depois a 100?C por 8 horas. Estas condi??es otimizadas foram utilizadas para efetuar o aumento de escala para o reator de 5 gal?es. As amostras de Al-SBA-15 foram submetidas a carboniza??o com o objetivo de preencher os poros da SBA-15 com material carbon?ceo e evitar o colapso de sua estrutura. As amostras carbonizadas foram utilizadas como fonte de s?lica para a s?ntese da mordenita em meio seco utilizando a t?cnica de transporte em fase vapor (VPT). O objetivo deste procedimento foi a obten??o de mordenita tendo mesoporos. Para o preparo da mordenita por VPT, v?rias condi??es foram utilizadas, variando o tempo de s?ntese e forma de adi??o dos reagentes, presen?a ou aus?ncia de um direcionador org?nico. As amostras obtidas foram caracterizadas por difra??o de raios X e adsor??o de nitrog?nio. Foi observado que na maioria dos experimentos n?o houve a forma??o da fase mordenita. Nos experimentos em que esta fase foi obtida, n?o foi observada forma??o de mesoporosidade significativa. Aparentemente, a presen?a de material carbon?ceo n?o foi suficiente para preservar a estrutura mesoporosa da SBA-15. Palavras chave:

The experimental design was completely randomized in a factorial 4x5 with four yeast strains (1, 2, 3 and 4) and five concentrations for each strain of 1x107, 5x107, 1x108, 5x108 and 1x109 CFU.mL-1 at pH 2 and 6.8 with three replicates per treatment. In vitro adsorption experiments were carried out in microcentrifuge tubes containing buffered solution mycotoxin and yeast at 39 ? C. The concentration of FB1 was 5 ?g.mL-1. The supernatant of samples containing fumonisin not adsorbed were analyzed and quantified by CLAE. The results of the in vitro adsorption were subjected to a regression analysis based on the S. cerevisiae concentration and yeast strains. It was observed at pH 2 and 6.8 a significant interaction between S. cerevisiae concentration and yeast strain (P <0.001). At pH 2, the the amount of FB1 adsorbed by different yeast strains did not differ with 1x107, 5x107, 1x108 CFU.mL-1, only showed effects for the highest concentrations of 5x108 and 1x109 CFU.mL-1 (P<0.001). At pH 6.8, the differences occurred to concentration of 1x108, 5x108 and 1x109 CFU.mL-1 (P<0.001), but had no effect on lower concentrations (5x107 and 1x107 celulas.mL-1). At the highest concentration of 1x109 CFU.mL-1, strain 4 (SC-47) demonstrated a greater capacity to adsorb FB1, 39.4% and 37.5% at pH 2.0 and 6.8, respectively. In addition, linear responses were observed in the adsorption capacity in all strains evaluated under conditions of acidic and neutral pH. The results demonstrate that the ability of S. cerevisiae to adsorb FB1 is strain-dependent and the pH value may influence the amount of FB1 removed from the solution according to the strain used / Avaliou-se a adsor??o in vitro de fumonisina B1 (FB1) atrav?s do uso de diferentes cepas e concentra??es de Saccharomyces cerevisiae em condi??es que simulam o trato digestivo de equinos. O delineamento experimental foi inteiramente casualizado em esquema fatorial 4x5, com quatro cepas de levedura (1, 2, 3 e 4) e cinco concentra??es para cada cepa de 1x107, 5x107, 1x108, 5x108 e 1x109 UFC.mL-1, sob pH 2 e 6,8 com tr?s repeti??es por tratamento. Os ensaios de adsor??o in vitro foram conduzidos em microtubos contendo solu??o tamponada de micotoxina e levedura a 39 ?C. A concentra??o de FB1 foi de 5 ?g.mL-1. As amostras do sobrenadante contendo as fumonisinas n?o adsorvidas foram analisadas e quantificadas por CLAE. Os resultados foram submetidos ? an?lise de regress?o em fun??o da concentra??o de levedura e cepas de levedura. Observou-se, tanto em pH 2 como a 6,8, intera??o significativa entre concentra??o de FB1 e cepa de levedura (P<0,001). No pH 2, as cepas de levedura n?o diferiram em rela??o a quantidade de FB1 adsorvida nas concentra??es de 1x107, 5x107, 1x108 UFC.mL-1, apenas apresentaram efeito significativo para as concentra??es mais elevadas de 5x108 e 1x109 UFC.mL-1 (P<0,001). Em pH 6,8, as diferen?as ocorreram para as concentra??es de 1x108, 5x108 e 1x109 UFC.mL-1 (P<0,001), n?o apresentando efeito significativo nas concentra??es mais baixas (1x107e 5x107 UFC.mL-1). Na concentra??o mais elevada de 1x109 UFC.mL-1, a cepa 4 (SC-47) demonstrou maior capacidade para adsorver FB1, 39,4% e 37,5% em pH 2,0 e 6,8, respectivamente. Al?m disso, foram observadas respostas lineares na capacidade de adsor??o em todas as cepas avaliadas sob condi??es de pH ?cido e neutro. Os resultados demonstram que a capacidade de adsor??o de FB1 pela S. cerevisiae ? cepa-dependente e que o valor de pH pode influenciar na quantidade de FB1 removida da solu??o de acordo a cepa utilizada.

First, an inventory (in the years 2005-2006) was performed of tick species occurring in Passeriformes of a forest fragment located on private property (21?37? S, 43?21? W), in the municipality of Coronel Pacheco, in the state of Minas Gerais, Brazil. This study verified the occurrence of Amblyomma nodosum, Amblyomma calcaratum, Amblyomma parkeri and Amblyomma longirostre in larval and nymph stages and Amblyomma ovale in the larval stage in Passeriformes from the aforementioned locality. It was also observed that Amblyomma larvae are most abundant in birds during the dry season when compared with the rainy season. Prevalence rates and mean intensity among bird families also showed to be high during the dry season, coinciding with the lowest level of tick aggregation, according to the discrepancy index (D). Regarding bird families, those with higher parasitic intensities were Thraupidae (16.51 ? 31.4), Furnariidae (22.3 ? 23.4) and Thamnophilidae (10.1 ? 14), when considering both seasons. Regarding bird ecological and morphological data, higher intensities were observed for omnivorous and understory birds and for birds with greater weights and lengths. Second, an assessment of reports on ticks occurring in wild birds of the Brazilian Atlantic Rainforest was performed. With these reports, the compilation of data regarding feeding ecology and bird sizes was performed, to verify the possible association of these variables with parasitism by ticks. In total, nine tick species have been reported in Atlantic Rainforest birds, especially A. longirostre, A. nodosum, A. calcaratum and Amblyomma aureolatum, in immature stages. The Thraupidae, Thamnophilidae, Pirpidae and Furnariidae bird families have the highest number of occurrences, respectively. A. longirostre was the species with the broadest parasitism spectrum among bird families, mainly occurring in the Thraupidae, Thamnophilidae, Pipridae, Rhynchocyclidae, Dendrocolaptidae and Turdidae families. As for A. nodosum, the main bird families parasitized by this species are Thamnophilidae, Thraupidae and Conopophagidae. With regard to A. calcaratum, a higher incidence was observed in birds from the Thraupidae, Thamnophilidae and Conopophagidae families, while for A. aureolatum its prevalence among the families of parasitized birds remained evenly distributed. When foraging and dietary habits were considered, it was found that insectivorous birds are associated with parasitism by these four tick species. Only A. nodosum, had no observed association with frugivorous birds. A. nodosum and A. calcaratum species are associated with birds that frequent interior forests, while bird species that frequent forest borders are associated with all of the species mentioned. Overall, there was an association between small birds (up to 40 g and 40 cm) and the tick species mentioned. It was concluded that the location commonly shared by wild birds and hosts of ticks in adult stages is an important factor for the occurrence of parasitism. / O presente trabalho teve como objetivo compreender aspectos ecol?gicos envolvidos no parasitismo por carrapatos em aves silvestres da Mata Atl?ntica. No Cap?tulo I, foram estudados carrapatos de aves Passeriformes, coletados nos anos de 2005 e 2006, provenientes de um fragmento de mata localizado numa propriedade particular (21?37? S, 43?21? W), em Coronel Pacheco, Minas Gerais. Neste trabalho foi verificada a ocorr?ncia de Amblyomma nodosum, Amblyomma calcaratum, Amblyomma longirostre e Amblyomma parkeri nos est?gios de larva e ninfa e Amblyomma ovale no est?gio de larva. Tamb?m foi poss?vel verificar que larvas do g?nero Amblyomma s?o mais abundantes nas aves durante a esta??o seca do que na esta??o chuvosa, conforme observado pelos ?ndices de preval?ncia e intensidade m?dia entre as fam?lias de aves, coincidindo com o menor grau de agrega??o dos carrapatos na esta??o seca, segundo ?ndice de discrep?ncia (D). As fam?lias de aves com maiores intensidades de parasitismo foram Thraupidae (16.51 ? 31.4), Furnariidae (22.3 ? 23.4) e Thamnophilidae (10.1 ? 14), quando consideradas ambas as esta??es. Quanto aos dados ecol?gicos e morfol?gicos das aves, foram verificadas maiores intensidades para aquelas on?voras e de sub-bosque e com maiores pesos e comprimentos. No Cap?tulo II, foram compilados os relatos de carrapatos do g?nero Amblyomma que ocorrem em aves silvestres da Mata Atl?ntica no Brasil. Com esses relatos, foi montado banco de dados sobre ecologia e morfologia das aves para verificar a poss?vel associa??o destas vari?veis com o parasitismo por carrapatos. Ao todo, nove esp?cies de carrapatos j? foram relatadas em aves deste bioma, com destaque para A. longirostre, A. nodosum, Amblyomma aureolatum, A. calcaratum e A. parkeri nas fases imaturas. As fam?lias de aves Thraupidae, Thamnophilidae, Pipridae e Furnariidae s?o as com os maiores n?meros de ocorr?ncias, respectivamente. A. longirostre ? a esp?cie com maior espectro de parasitismo sobre as fam?lias de aves, ocorrendo principalmente nas fam?lias Thraupidae, Thamnophilidae, Pipridae, Rhynchocyclidae, Dendrocolaptidae e Turdidae. As principais fam?lias de aves parasitadas por A. nodosum s?o Thamnophilidae, Thraupidae e Conopophagidae. Para A. calcaratum, foi verificada maior ocorr?ncia em aves das fam?lias Thraupidae, Thamnophilidae e Conopophagidae, enquanto para A. aureolatum a preval?ncia entre as fam?lias de aves se manteve homogeneamente distribu?da. Quando considerados os h?bitos ecol?gicos, foi verificado que aves inset?voras est?o associadas com parasitismo destas esp?cies de carrapatos. Apenas para A. nodosum, n?o foi observada associa??o com aves frug?voras. As esp?cies A. nodosum e A. calcaratum est?o associados com aves que frequentam interior de mata, enquanto aquelas esp?cies de aves que frequentam borda de mata est?o associadas com todas as esp?cies citadas. De maneira geral, foi observada associa??o entre aves pequenas (at? 40 g e 40 cm) e as esp?cies de carrapatos citadas. Foi poss?vel concluir que o local, onde aves silvestres e hospedeiros das fases adultas de carrapatos compartilham ? fator importante para a ocorr?ncia de parasitismo.

The study was conducted based on the intersection of oral and written sources, as well as the participant observation, which was systematized in the field journal. The Movement of Agricultural Women (MMA) emerged in the eighties due to the need for guaranteeing social rights such as retirement and paid maternity leave for women farmers, this being one of the first fights of the movement. In its trajectory, the MMA joined the National Articulation of Rural Women Workers (ANMTR) in the mid-nineties, whose emergence was an embryo for the consolidation of the MMC, created in 2004. With the MMC, which brings together different organizations of rural women workers in Brazil, among them the MMA, emerged a peasant political identity and a defense of an ecological and feminist peasant agricultural project. It is perceived that the discussions regarding feminism gained prominence, especially through the dialogue with Agroecology, and have also been consolidated with the emergence of a new political category within the MMC / SC, the young peasants. Finally, it is considered that the construction of peasant feminism by the MMC / SC is the core element to guide the creation of more egalitarian relationships between men and women, constituting as part of a new rurality / O presente trabalho teve como objetivo geral analisar a trajet?ria do Movimento de Mulheres Camponesas (MMC) no Oeste de Santa Catarina. A pesquisa foi realizada com base no cruzamento de fontes orais e escritas al?m da observa??o participante que foi sistematizada no di?rio de campo. O Movimento de Mulheres Agricultoras (MMA) surgiu nos anos 1980 na busca pela garantia de direitos sociais como aposentadoria e sal?rio maternidade ?s agricultoras, o que exigiu o reconhecimento profissional das mulheres agricultoras, sendo esta uma das primeiras bandeiras de luta do movimento. Em sua trajet?ria, o MMA passou a integrar a Articula??o Nacional de Mulheres Trabalhadoras Rurais (ANMTR) em meados dos anos 1990, cujo surgimento foi um embri?o para a consolida??o do MMC, que foi criado em 2004. Com o MMC, que re?ne diversas organiza??es de mulheres trabalhadoras rurais do Brasil, dentre elas o MMA, emerge a identidade pol?tica camponesa e a defesa de um projeto de agricultura camponesa ecol?gica e feminista. Percebe-se que as discuss?es sobre feminismo ganharam destaque, sobretudo, a partir do di?logo com a Agroecologia e v?m se consolidando tamb?m com a emerg?ncia de uma nova categoria pol?tica no MMC/SC, a de jovens camponesas. Por fim, percebe-se que a constru??o de um feminismo campon?s pelo MMC/SC ? central para orientar a cria??o de rela??es mais igualit?rias entre homens e mulheres, constituindo-se como elemento de uma nova ruralidade

It is emphasized the relationship between theory and practice in technical training which encourages the understanding of content and the development of the capacity to articulate the various knowledge to contextualize them in their actions to achieve meaningful learning. It is justified due to the perception of traditional teaching methodologies observed as inefficient to help students learn to think, ponder, create solutions to the problems students face and apply their knowledge in the day-to-day experiences. The research was performed at the Federal Institute of Esp?rito Santo - Itapina campus with 16 students of the second / third period (freshmen and sophomores) of Technician in Agricultural in the subsequent mode, who are from ES, MG and BA states, and who have completed high school education in public schools. The activities of the curriculum components directly related to the topic discussed were developed in the 2nd semester of the school year, in 2014 and the first semester of the next school year, in 2015, with the collaboration of seven teachers and the effective participation of two teachers. The methodology applied was the Project Pedagogy and as research instruments were used questionnaires with open and closed questions, technical visits, seminar, debate and drill. The first questionnaire was applied at the beginning of the proposed activities and the second questionnaire, after technical visits and wrap up seminar of the activities developed during the academic year in 2014. In the first semester of the school year in 2015 a debate was held after the registration of students? prior knowledge on "Zoonotic Diseases transmitted by milk: Brucellosis versus Tuberculosis" followed by a practical training for vaccinators, whose proposal has become an ongoing project resulting in certification for students. The completion of the research was a self-evaluation of the activities carried out by students. The results showed growth of students in conceptual as well as procedural and attitudinal fields, and development of their critical awareness and social responsibility related to the problematized reality. It is concluded that the encouragement to research based on students? socio-cultural experience, and the relationship between theory and practice in technical training, are fundamental tools for the development of multiple knowledge to young people, future agents of changing of the environment in which they live / A presente pesquisa teve como objetivo estimular o processo de constru??o do conhecimento dos educandos acerca de seguran?a alimentar aplicando a pedagogia de projetos cujo tema desenvolvido foi qualidade do leite.

Among these agents, OH radicals, ozone and nitrate radicals are the most important. In coastal zones, chlorine atoms are also important specie for the chemical removal of primary and secondary pollutants. This work aims the kinetic study of the gas phase reaction between chlorine atom and formaldehyde, H2CO + Cl ? HCO + HCl. The reaction was described at HF, MP2, CCSD, QCISD and DFT (B2PLYP, MPW2PLYP and MPWKCIS1K) levels. Basis set effect was also explored and the aug-cc-pVDZ (ACCD) and aug-cc-pVTZ (ACCT) basis set were adopted. Geometry optimizations and vibrational frequencies calculations were performed for reactants and products. A prebarrier complex was located at all levels of theory, stabilized with respect the isolated reactants by ca. 4 kcal mol-1. Saddle points were located and characterized by their imaginary frequencies. Energy barriers were predicted as ca. 1 kcal mol-1, in agreement with experimental results (0.7 ? 1.0 kcal mol-1). Rate coefficients were calculated in the range from 100 to 500 K, adopting the canonical variational method, as available in the kcvt code. The calculated kinetic parameters, rate coefficients (k, 298 K, expressed in 10-11 cm3 molecule-1 s-1), activation energy (Ea, expressed in kcal mol-1) and Arrhenius preexponential factor (A, expressed in 10-11 cm3 molecule-1 s-1) were: k = 4.89, Ea = 0.25 and A = 7.45. The results suggest that a reaction dynamics is well described by a mechanism taking into account a prebarrier intermediate. Canonical variational rate coefficients were predicted in good agreement with experimental data, validating the proposal for the reaction mechanism introduced in this study / Os estudos em Qu?mica Atmosf?rica permitem entender o comportamento qu?mico de diversos poluentes atmosf?ricos frente a agentes oxidantes presentas na troposfera.

Ainda em zonas costeiras, ?tomos de cloro tornam-se tamb?m importantes esp?cies para a remo??o qu?mica de poluentes prim?rios e secund?rios. Este trabalho visa o estudo cin?tico da rea??o H2CO + Cl ? HCO + HCl em fase gasosa. A rea??o foi descrita em n?veis HF, MP2, CCSD, QCISD, DFT (B2PLYP, MPW2PLYP e MPWKCIS1K) Tamb?m o efeito da base foi explorado e, para tanto, as bases aug-cc-pVDZ (ACCD) e aug-cc-pVTZ (ACCT) foram adotadas. C?lculos de otimiza??o de geometria e frequ?ncia vibracionais foram feitos para reagentes e produtos. Foram vistos tamb?m para todos os n?veis de c?lculo a forma??o de um pr?-complexo estabilizado, em rela??o aos reagentes isolados, por cerca de 4 kcal mol-1. Ponto de sela tamb?m foram otimizados e identificados pela frequ?ncia vibracional imagin?ria. Barreiras de energia foram previstas em cerca de 1 kcal mol-1, em acordo com a previs?o da literatura, 0,7 - 1,0 kcal mol-1. Os coeficientes de velocidade foram calculados na faixa de 100 ? 500 K a partir da teoria do estado de transi??o variacional com auxilio do programa kcvt. Os par?metros cin?ticos encontrados, coeficientes de velocidade (k, 298 K, expressos em 10-11 cm3mol?cula-1s-1), energia de ativa??o (Ea, expresso em kcal mol-1) e fator pr?-exponencial (A, expresso em 10-11 cm3mol?cula-1s-1) foram: k298K = 4,89, Ea = 0,25 e A = 7,45. Os resultados sugerem que a din?mica da rea??o ? bem descrita a partir de um mecanismo que contempla a participa??o de um intermedi?rio pr?-barreira. Resultados de coeficientes de velocidade variacionais can?nicos obtidos neste trabalho se mostraram satisfat?rios quando comparados a dados experimentais validando a proposta de mecanismo trazida nesse trabalho.

Since past decades, megaprojects (steel industry, logistics and the military industry) have been both setting up and expanding local economic growth. Population flows are been detecting as part of this new economic pathway as well the consequently increasing of households within a territory that has geographical aspects unfavorable to this fast expansion. By these issues there is the need for urban planning headed by municipal government in order to creating public policies and programs that aim to improve the population quality of life. The work has as a temporal focus the decades between 2000/2010 because important historical descriptions were detected. Bibliographical research, data analysis and field research were used as methodological tools having been fundamentals to conclusion: the existing concern of the precarious situation of the municipality with the basic sanitation sector. / O presente trabalho tem como objetivo identificar como o munic?pio de Mangaratiba vem se planejando e capacitando na quest?o de saneamento b?sico (abastecimento de ?gua e esgotamento sanit?rio) diante da press?o exercida pelas mudan?as demogr?ficas influenciadas pelos megaempreendimentos localizados na zona costeira da ba?a de Sepetiba. Ao longo das ?ltimas d?cadas, megaempreendimentos ligados ao setor sider?rgico, ? estrutura log?stica e ? constru??o de submarinos est?o se instalando/ampliando nessa regi?o, influenciando no aumento populacional e consequentemente, no aumento de domic?lios dentro de um territ?rio que possui aspectos geogr?ficos pouco favor?veis a sua expans?o. Diante desses fatores, ocorre a necessidade de planejamento por parte da administra??o p?blica municipal, criando pol?ticas p?blicas, planos e programas que tenham como objetivo melhorar a qualidade de vida da popula??o permanente, de uso ocasional e tamb?m tur?stica. O enfoque temporal deste trabalho ? para a d?cada 2000/2010, por?m ocorrem descri??es hist?ricas importantes a partir da d?cada de 1970, servindo como base para a principal d?cada em estudo. Atrav?s de pesquisas bibliogr?ficas, an?lise de dados e pesquisa de campo, este trabalho foi elaborado diante da preocupa??o existente da situa??o prec?ria do munic?pio com o setor de saneamento b?sico. A incapacidade de demanda do munic?pio com abastecimento de ?gua e a n?o exist?ncia de tratamento e coleta de esgoto, fazem com que, respectivamente, a maioria da popula??o utilize ?gua de nascentes (sem tratamento) e que grande parte dos domic?lios continuem poluindo o meio ambiente, atingindo de forma direta a popula??o. Lan?ado no ano de 2013, o Plano Municipal de Servi?o P?blico de Abastecimento de ?gua e Esgotamento Sanit?rio n?o entrou em opera??o em sua grande parte e, de acordo com a Prefeitura, vem sendo revisado e adequado, por?m sem prazo para estar finalizado

Samples were collected during 15 nights distributed during the transition period between dry and flooding seasons (end of November to mid-December 2014). A second survey was carried out during the dry season (October 2015). Several vegetational formations were sampled, considering both open (pastures, fields with mounds) and forest areas (cambara and the palm Scheelea phalerata, Arecaceae, as dominant species), totaling 24 sites. Samples were collected by mist nets set at ground level among trails, clearings in the forest, grazing areas and savanna formations (fields with mounds). A total of 27 species within five families were recorded: Emballonuridae (one species), Phyllostomidae (11 genera and 16 species), Noctilionidae (one genus and two species), Molossidae (two genera and three species) and Vespertilionidae (two genera and five species), although species from almost all trophic categories were captured. The richest trophic group was the insectivores with 48% of the species. However, its capture was relatively rare in most study sites. The highest abundance was for the frugivorous trophic guild with 68.9% of the total (454 individuals). The group is widely distributed in the mosaic, may be due to the capture method (mist nets) and to the high representation of the fruit bats subfamily Stenodermatinae in the study region. The Phyllostomidae species, considered sensitive to habitat disturbances, were captured in some of these patches. Four large groups of areas were identified, when composition of species, trophic structure, as well as the foraging strategies were considered. Insectivores were more associated with sparse vegetation areas or open fields, tending to areas closer to water, such as rivers with bridges or artificial tanks (cattle water holes) and seasonally flooded vegetation such as cambara forest. Frugivorous had the highest capture rates in acuri forest, semi-deciduous forest physiognomy with understory dominated by palm trees "acuri" (S. phalerata), indicating shelter availability. Thus, species occurrence seems to be related to trophic habits and foraging strategy, and are primarily distributed according to the vegetation zones of the study region. / Foi realizado um levantamento da quiropterofauna e avaliadas as suas rela??es com o mosaico da paisagem na regi?o situada ? margem esquerda do rio S?o Louren?o (Fazenda Santa L?cia) no norte do Pantanal, MT. As coletas foram realizadas durante 15 noites distribu?das entre o per?odo de transi??o entre a seca e a cheia (final de novembro at? meados de dezembro de 2014). Uma segunda amostragem foi desenvolvida no per?odo da seca (outubro de 2015). Diversas forma??es foram amostradas, considerando ?reas abertas (pastagens, campos com murundus) e fechadas (cambarazais, acurizais), com um total de 24 s?tios avaliados. As coletas foram realizadas com redes de neblina (mist-nets). Essas foram armadas no n?vel do solo em trilhas, clareiras dentro da mata, ?reas de pastagem e forma??es de cerrado (campos com murundus). No total foram registradas 27 esp?cies de cinco fam?lias: Emballonuridae (uma esp?cie), Phyllostomidae (11 g?neros e 16 esp?cies), Noctilionidae (um g?nero e duas esp?cies), Molossidae (dois g?neros e tr?s esp?cies) e Vespertilionidae (com dois g?neros e cinco esp?cies). Embora as esp?cies de morcegos de quase todas as categorias tr?ficas tenham sido registradas, a maior representatividade foi de inset?voros com 48% das esp?cies capturadas. Contudo, sua abund?ncia mostrou-se relativamente rara na maioria dos s?tios avaliados. A maior abund?ncia foi da guilda tr?fica frug?voro com 68,9% do total (454 indiv?duos), sendo esta amplamente distribu?da no mosaico avaliado, o que pode ser devido ao m?todo de captura com redes de neblina e a elevada representatividade de morcegos frug?voros da subfam?lia Stenodermatinae na regi?o de estudo. Esp?cies de Phyllostomidae, consideradas sens?veis a perturba??es no habitat, foram capturadas em algumas dessas machas. Quando comparadas as similaridades entre as ?reas, foi observada uma separa??o em quatro grandes grupos, tanto quanto a composi??o de esp?cies quanto a estrutura tr?fica e modo de forrageio. A distribui??o observada para os inset?voros esteve mais associada a ?reas com vegeta??o esparsa ou campos abertos, com tend?ncia para ?reas mais pr?ximas aos locais com ?gua como rios com pontes ou tanques artificiais (?gua para o gado) e vegeta??o estacionalmente inund?vel como os cambarazais. Os frug?voros apresentaram as maiores taxas de captura em acurizais, fisionomia florestal semidec?dua com sub-bosque dominado pela palmeira ?acuri? (Scheelea phalerata, Arecaceae), indicando boa disponibilidade de abrigos sob a vegeta??o ou folhagem. Assim sendo, a distribui??o das esp?cies parece estar diretamente relacionada ao habito alimentar e ao modo de forrageio e est?o distribu?das principalmente de acordo com as zonas de vegeta??o da regi?o estudada.
