Companies need to know their environment, their strengths and their weaknesses in relation to competitors, so that they get benefits, consolidating themselves in this environment. In great companies, there are best conditions to perform self-knowledge studies and market studies internally, or still hiring agencies which make such studies. This is more difficult to happen in small or medium companies. In that way, studies with the purpose of producing a diagnosis for a company or for an industrial segment become important, mainly for small or medium companies, not only for the involved companies, but also for the scientific community, that can focus their research efforts in subjects that are of interest for the companies as for the scientific community. The objectives of this dissertation are to propose a methodology for diagnosing problems and needs in the productive area of small-medium sized industrial companies and its application in two different industrial segments: make-to-order foundries of the interior of São Paulo state and footwear manufacturers of Birigui-SP. The methodology consists in a survey (evaluation research), using questionnaires and interviews. The survey and the use of the inductive method of research make possible a visualization of the situation faced by the industrial segment in study. The application of the proposed methodology was able to show many production characteristics of the segments: make-to-order foundries of the interior of São Paulo state and footwear manufacturers of Birigui-SP.

A lack of support to teachers in the instructional material creation was verified during a research with computer-based distance learning environments, this support being related both to technological and pedagogical aspects. To propose a support in these two fields, technology and pedagogy, this work analyzed the learning theories. From this analysis arose the opportunity to adapt the cognitive strategies' ideas as a pedagogical support to the teacher in the content organization of the instructional material. In addiction, as the material format to the Web has a different structure from the conventional one, it was defined a basic set of usability directives and explanations about these differences, as another form of support to the teacher. The Cognitor, an instructional material creation tool was developed, joining its technological support in the material creation for the Web, with the pedagogical support mentioned previously.

Citrus canker is one of the main threats to the sanity of orange groves in the production region of the State of Sao Paulo, known as Citrus Belt. This disease has caused the elimination of million of trees and losses to the whole citrus production chain. Despite the official measures to canker eradication, growers can prevent having the disease in their groves adopting simple measures, recommended by FUNDECITRUS Fund for Citriculture Defense. These measures could be standardized and implemented in the citrus farms using approaches and tools for quality management by means of a management system upon which a phytossanitary quality certificate for citrus canker prevention can be established. This certificate could contribute do the to the reduction of the risks of occurrence and to the reduction of costs for the canker prevention and eradication. Besides that, the phytossanitary quality certificate could originate the establishment of a quality and origin certificate for the orange produced in the Citrus Belt, aiming the valuation of the state citriculture in internal and foreign orange markets, following the recent trends of quality certification of agro-food products and companies. The model for citrus canker prevention management system is proposed from a survey of quality certification systems in agrofood chains and the ISO 9000:2000 standards, SQF 2000 code and IFP Integrated Fruit Production system guidelines. A survey with 64 growers has been conducted to evaluate the adoption of prevention measures recommended by FUNDECITRUS and the growers´ perception of the prevention measures and of an eventual phytossanitary quality certificate for citrus canker prevention.

Multimedia applications are heavily used in computing environments, since they provide a lot of resources and interaction with the user. Taking into account the advantages provided by multimedia applications, resources became more complex requiring good programming knowledge to develop them. To facilitate multimedia applications developing, many tools have been created. This work describes a proposal of a multimedia application authoring tool which aims to provide additional resources to those traditionally found in the existing authoring tools. This tool can be used on the Internet and has an associated database, where there are medias and applications available which can be selected by semantic queries in order to assist the author in the design of his own multimedia application.

In the last decades, most of the organizations has faced strong technical changes rather than managerial changes in terms of the performance evaluation. Such unbalance can mislead the achievement of all promised outputs of technical changes. Performance measurement could play an important role to reestablish the lost balance. Unfortunately, the traditional performance measurement systems, consistent with mass production systems, are inappropriate and the researchers and practitioners have been searching for new performance measurement frameworks. An extensive literature review has pointed out a lack of a comprehensive method to assess the performance measurement practices, i.e., there is a risk of changing the performance measurement practices with no information what the organization is really doing now. This dissertation aims to help to fill this gap developing a Comprehensive Performance Measurement Assessment Method. The method was developed from both a literature review and exploratory case study. It combines the existing methods from literature in a logical sequence in order to assess the performance measurement practices in three dimensions: individual performance measures, performance measurement system and the environment which it interacts.

This work research intends to rescue and to analyse the experience of the descentralized urban planning district planning, developed by town hall of Santo André in different moments of its history. We discussed about the concept principles of the descentralized urban planning of district, trying to estimate the possibility of a positive impact of this conception over the urban ambient. By the way, guidelines as the recue of the sociability, neighbourhood relationships and ecomonomic development that is distributed ina balanced way in the urban area are estimated from that concept, that is investigated and evaluated from the projects discussion made by the town hall of Santo André, mainly, about the programs Viva Cidade and Centros e Bairros. The analyse of the impacts of the pilot-projects of the program Centros e Bairros impacts, in Santo André, try to recognise the capacity of transformation of the urban area and the population relationship, especialy, the impacts over the descentralized economic development and more balanced than this proposals that take with them urban and social conceptions.

At the actual moment on What ecology supportable concerned to the diferent ecossistems depend on the balance between the environment and the development, this research has as a goal to realize the characterization, analyse and elaborate an ecological-economic zoning conceptual proposition to the Frederico Westphalen municipality, state of Rio Grande do Sul, Brazil, adapting to a feasible methodology: a methodology founded on the use of the Geography Information Systems GIS, to elaborate a georeferenced digital data base which allow to understand the structure and the functioning of the natural systems, on purpose of a management supported on the natural borough resources. The borough environment characterization and zoning which present, nearby 262 km2 and 26.759 inhabitants were developed based on topography maps DSG and digital satellite images. The results embody to elaborate maps that refer to the structural landscape elements and to some environmental impact risks, while to the definition and analyse of handled zones proposed the thematic digital maps were overlap using the Analysis of Crossed Impact based on presupposed existence of interrelation of future events and the Intuitive Logic Analyse. This procedure permits to divide the borough area in five zones that present the degree of distinguished environmental fragility. The zones are: the greater environmental frail relative zone ZMAF; average environmental frail relative zone ZMEF; the greater environmental stability relative one ZMAE; urban zone ZMRB and urban expansion zone ZEUR. ZMAF and ZMEF zones take the greatest part of the borough 45,l8% and 36,25% respectively. Based on the problems, potentialities and limitations analyse, it was possible spatialyse the evolution of the environmental degradation process concerned with the use of the natural resources coming from the main economic activities and, based on this analyse, identifying the economic tendency of the region by the economic production of the conflicts using the life population conditions, directioning to a desire way. The methodology used allowed to fix up guidelines into two degrees: one of them is the general covering to all the zones that embody the borough (general guidelines) and, another directed to each managed zone proposed (specific guidelines). Both the general guidelines as the specific ones were elaborated based on criterions and principles established on the diagnosis of the current situation and has as a goal to the natural characteristics of each area while the potentialities are priority.

Environmental analysis and land use dynamics of the landscape northwest area of the Rio Grande do Sul Province. With the growing demand for natural resources the environmental analysis and the periodic diagnosis of the land use started to represent a fundamental aspect for the understanding of the occupation patterns and spatial organization of the landscape, rarely permanent in function of the dynamics of the human activities. In this context, information obtained by orbital sensor, allied to the geocoded techniques constitute a fundamental tool to the landscape structural characterization and for the identification, mapping and environmental diagnosis of the natural resources. This work had as objectives the delimitation, and the environmental analysis and diagnosis of five watershed of the landscape northwest area of the Rio Grande do Sul Province, for the identification of the risks associated to the soil erosion and of the degree of compromising of the environmental quality related to fragmentation and loss of natural areas, that these landscape mapping units were submitted in the period from 1984 to 1999. The Geographical Information Systems (GIS) were essential to obtain information related to the structural characteristics of the landscape represented by the hypsometriy, clinografy, road net, hydrografy, land use types, and critical risks to soil erosion and permanent preservation areas. Agriculture represented the principal land use type in the period among 1984 to 1999, demonstrating the need to promote the control of the agricultural practices, mainly the execution of the environmental legislation toward to the establishment of permanent preservation areas. The application of Principal Components Analysis associated to the software Fragstats allowed to identify the principal parameters to explain the fragmentation process and of the land use spatial and temporal pattern related to forest and capoeira use classes, besides a compromising gradient of the environmental quality of the watershed. The Lajeado Perau and Rio Pardo were considered the minus, and the Lajeado Castelinho and Lajeado Mico the more committed watershed. The cartographic database represents an essential contribution for the watershed environmental management proposal in the perspective of the regional sustainbility.

Hemoglobin electrophoretic patterns, oxygen equilibrium experiments using unfractionated blood, stripped hemoglobin at 4oC, 21oC, 40oC, as well as the effect of inositol hexaphosphate (IHP) and 2,3-biphosphoglycerate (BPG), and the qualitative and quantitative determination of intraerythrocytic organic phosphate were done, in three species of Aves: Athene cunicularia – owl (Order Strigiformes, Family Strigidae), Coragyps atratus - vulture (Order Ciconiformes, Family Cathartidae) and Mimus saturninus - mocking bird (Order Passariformes Family Mimidae). On starch gel electrophoresis, pH 8.6, A. cunicularia and C. atratus showed one slow anodic major component and one fast minor components, a typical bird hemoglobin pattern. On the same electrophoretic conditions, M. saturninus showed two anodic major components, instead one major and one minor. Stripped hemoglobins at the three temperatures, in the presence of IHP, BPG, and blood showed normal Bohr effect and n values (Hill plots) were close to one, indicating very low or no cooperativity. Oxygen affinities were temperature-dependent (as lower the temperature higher is the affinity), BPG modulation was low, IHP was very effective as negative modulator. Vulture hemoglobin showed the highest P50 value, while the owl and the mocking bird presented lower and similar oxygen affinity to each other. No AMP, GTP and BPG were found, only ADP, ATP and inositols were detected in the erythrocytes of the three species. Inositol pentaphosphate (IP5) was the most abundant intraerythrocytic organic phosphate in the 3 species. A. cunicularia showed also inositol tetraphosphate and C. atratus and M. saturninus showed IHP, besides IP5. Although the three species belong to different Orders, have different habit; the functional properties of their hemoglobins are very similar. One hypothesis to explain such similarity is that the avian system to deliver and discharge oxygen to the tissues are so efficient, that works properly in a wide range of situations

This work proposed an environmental zoning based on the potencialities and fragilities of the use of the land. Its perspective was to subsidize the elaboration of proposals and lines of direction for the re-ordering of the landscape of the municipality of Erechim, contributing to local-regional development. The town is a part of the Geographic Micro-region of Erechim, inserted phisiographically in a portion of Brazil s Southern Plateau in the center of Rio Grande do Sul State. Based on the understanding that spatial order can be an instrument of environmental policy, the landscape was studied through overlapping techniques of thematic maps, aiming to promote the protection of the environment, the presevation of its quality and sustainable usage of its natural resources. The production and analysis of the maps was performed using Geopraphic Information Systems, LANDSAT satelite images and aerial photographs and a cartographic basis. The obtained analysis (mapping of phisycal environment) was subsidized by intensive field work, trying to represent the dynamics and functioning of each portion (units of landscape analysis). The environmental analysis of the area of study consisted in: characterizing the area of study acording to its environmental compartments; analyzing the diferents uses of the land; determining and characterizing the units of landscape analysis; elaborating a proposal for the handding of the landscape (environmental zoning). It was possible to propose actions for reduction of environmental degradation and protection of local-regional biodiversity from the synthesis of these analysis. Although one is aware that the work must be continued, this research represents a first step towards the elaboration of proposals and lines of direction for the space re-ordering of landscape within the concep of environmental planning.

The greater number of scientific works toward investigation of potentially and efficiency of agricultural industries study cattle breeding and agricultural sectors using their agrifood chains. On the other hand, fewer papers have investigated the aquaculture sector and its chains. This work hope to contribute to the development of aquaculture sector, evaluating the viability of shrimp farming of São Paulo (Brazil). For this purpose, we used a methodological approach which realizes analyses from competitiveness indicators of productive chains. This method consists of the identification, from its chain segment and its institutional environment, of the major competitiveness and efficiency drives. These analyses have not been still applied on studies of viability. The option for this methodology is justified because many viability studies have considered benefit-cost analysis. This analysis show low efficient when it is applied though on the productive chain level. The environment evaluation enables the identification of factors which affect competitiveness performance shrimp farming of São Paulo. The results demonstrated that both methodology can be used for the viability studies and shrimp farming of São Paulo should be improved its marketing channel and its processing industry.

Deficit of water and sodium in the body is detected by receptors located in different parts of the body. These receptors or hormones signalize to specific areas in the brain that control renal responses and water and sodium intake. Among these areas are: organum vasculosum of the lamina terminalis (OVLT), subfornical organ (SFO), anteroventral third ventricle (AV3V) region, hypothalamus, amygdala, septal area (SA), nucleus of the solitary tract (NTS), area postrema (AP) and lateral parabrachial nucleus (LPBN). Besides the regulation of fluid and electrolytic balance, these areas are also involved in cardiovascular control. Angiotensin II (ANG II) is a peptide that induces water and sodium ingestion and participates in cardiovascular regulation. Other neurotransmitters, like serotonin, cholecystokinin and atrial natriuretic peptide, can inhibit water and sodium intake. Another important inhibitory mechanism for water and sodium intake is related to central α2-adrenergic/imidazoline receptors. Central injection of the anti-hypertensive drugs, moxonidine and clonidine (α2-adrenergic/imidazoline receptor agonists), reduces water and sodium intake in different protocols (water dehydration, 24 h sodium depletion and administration of ANG II). So, the goals of this study were: a) to study the effects of moxonidine injected into the cerebral ventricles (lateral ventricle - LV and 4th ventricle - 4th V), amygdaloid complex, central nucleus of amygdala (CNA), basal nucleus of amygdala (BNA) and lateral hypothalamus (LH) on 0.3 M NaCl intake induced by sodium depletion (treatment combining subcutaneous injection of furosemide + sodium deficient food for 24 h); b) to test the effects of moxonidine injected into LV, 4th V and LH on the pressor response produced by the injection of ANG II and carbachol (cholinergic agonist) into the LV; c) to investigate the participation of α2-adrenergic receptors on the effects of moxonidine, injected into LV, on sodium depletion-induced 0.3 M NaCl intake and ANG II-induced pressor response; d) using imunohistochemical technique, to detect c-fos protein in forebrain areas after moxonidine injection into LV in normovolemic rats, sodium depleted rats or rats that were treated with central injection of ANG II. Male Holtzman rats with a stainless steel guide-cannulas implanted into the cerebral ventricles: LV (volume of injection: 1-3 µl) and 4th V (volume of injection: 1 µl); unilaterally into LH (volume of injection: 0.5 µl) and bilaterally into the amygdaloid complex (volume of injection: 1 µl), CNA (volume of injection: 0.2-0.4 µl) and BNA (volume of injection: 0.2-0.4 µl) were used. Moxonidine (20 nmol) injected into LV reduced sodium depletion-induced 0.3 M NaCl intake during all the period of the experiment (120 min), while moxonidine injected into 4th V, reduced 0.3 M NaCl intake only in the first 60 min. Bilateral injections of moxonidine (5, 10 and 20 nmol/1 µl) into amygdaloid complex and BNA (20 nmol/0.4 µl), but not into CNA, reduced sodium depletion-induced 0.3 M NaCl intake. Unilateral injection of moxonidine into LH did not change sodium depletion-induced 0.3 M NaCl intake. These results show that the activation of α2-adrenergic/imidazoline receptors produced by the injection of moxonidine into LV, 4th V and amygdaloid complex (especially into the BNA), but not into LH and CNA, reduce hypertonic NaCl intake. To investigate the role of the α2-adrenergic receptors on the inhibitory effect of moxonidine on 0.3 M NaCl intake, specific α2-adrenergic receptor antagonists, such as RX 821002, yohimbine and SKF 86466, were combined with moxonidine. The results show that icv injection of RX 821002 (40 and 80 nmol) and SKF 86466 (640 nmol) abolished the inhibitory effect of moxonidine (20 nmol) on 0.3 M NaCl intake during all the period of the experiment, while yohimbine (320 nmol) abolished the antinatriorexigenic effect of moxonidine only in the last hour of the experiment (60 to 120 min). These results suggest the involvement of central α2-adrenergic receptors on the inhibitory effect of moxonidine on sodium depletion-induced 0.3 M NaCl intake. Besides, we observed an increase on sodium depletion-induced 0.3 M NaCl intake following the treatment with RX 821002 (40 nmol) and yohimbine (320 nmol) alone, that suggests a possible tonic function to the central α2-adrenergic receptors on the control of hypertonic NaCl intake. The injection of moxonidine alone (respectively, 20 and 80 nmol) into LH and VL did not change mean arterial pressure (MAP) and heart rate (HR), while moxonidine administered into 4th V produced hypotension and bradycardia. The 80 nmol dose of moxonidine injected into LV reduced the pressor response produced by central injections of ANG II (50 ng) and carbachol (4 nmol). Moxonidine (20 nmol) injected into LH and 4th V reduced the ANG II-induced pressor response, but not carbachol-induced pressor response. So, it was demonstrated that central injection of moxonidine reduces the pressor responses produced by angiotensinergic (mainly) and cholinergic activation (in a minor degree). The injection of yohimbine (320 nmol) into the LV abolished the inhibitory effect of moxonidine (80 nmol), also injected into LV, on the pressor response produced by icv injection of ANG II, suggesting that moxonidine acting through central α2-adrenergic receptors inhibits ANG IIinduced pressor response. The injection of moxonidine into LV in normovolemic and satiated rats induced the expression of c-fos protein in the following areas: OVLT, ipslateral lateral septal area (ipsLSA), ventral median preoptic nucleus (vMPN), paraventrivular nucleus (PVN) and supraoptic nucleus (SON). These areas are involved in the fluid and electrolytic balance and cardiovascular regulation. ANG II injected into LV produced c-fos expression in the following areas: ipsLSA, dorsal median preoptic nucleus (dMPN), PVN and SHN and reduced cfos expression in contLSA (contra lateral lateral septal area). Previous injection of moxonidine did not change the c-fos protein expression induced by central injection of ANG II. Separated treatments with moxonidine and ANG II produce c-fos expression in similar areas, so it is difficult to know which treatment is responsible to c-fos protein expression observed after the combination of the two treatments. Maybe, moxonidine could be inhibiting the c-fos expression induced by ANG II and the c-fos expression noted after the combined treatment could be produced only by moxonidine. In sodium depleted rats, icv injection of moxonidine induced an increase on c-fos expression in ipsLSA and dMPN, and a decrease in OVLT, suggesting that changes in the activity of these areas could be responsible to the inhibitory effect of moxonidine on 0.3 M NaCl intake. In summary, the results showed: a) moxonidine injected into LV, 4th V, amygdaloid complex and BNA, but not into LH and CNA, inhibits sodium depletion-induced 0.3 M NaCl intake; b) RX 821002, yohimbine and SKF 86466 (specific α2-adrenergic receptor antagonists) abolished the inhibitory effect of moxonidine on 0.3 M NaCl intake, suggesting that the inhibitory effect of moxonidine is mediated through α2-adrenergic receptors. RX 821002 and yohimbine increased sodium depletioninduced 0.3 M NaCl intake, suggesting a possible tonic role of α2-adrenergic receptors on the inhibition of NaCl intake; c) moxonidine injected into LV, 4th V and LH reduced the pressor response produced by central angiotensinergic activation, while moxonidine injected only into LV was able to reduce the pressor effect of carbachol. Therefore central injection of moxonidine can inhibit mainly the ANG II-induced pressor response and only partially carbachol-induced pressor response. The reduction on ANG II-induced pressor response produced by moxonidine injected into LV was abolished by the pre treatment with yohimbine, suggesting the involvement of central α2-adrenergic receptors on the inhibitory effect of moxonidine on the pressor response produced by angiotensinergic activation; d) in normovolemic and satiated rats, moxonidine injected into LV induced c-fos expression in several cerebral areas: OVLT, ipsLSA, vMPN, PVN and SON. ANG II (50 ng) injected into LV increased c-fos expression in the following areas: ipsLSA, dMPN, PVN and SHN and reduced c-fos expression in contLSA. The icv injection of moxonidine did not change de c-fos expression induced by ANG II. e) in sodium depleted animals, the icv injection of moxonidine induced an increase in c-fos expression in ipsLSA and dMPN and a reduction in OVLT, suggesting that changes in the activity of these areas could be responsible to the inhibitory effect of moxonidine on 0.3 M NaCl intake in this protocol.

This survey was fomented by the hypothesis of a relationship between the appearance of the SERVIÇO NACIONAL DE APRENDIZAGEM INDUSTRIAL (SENAI) (National Service of Industrial Learning) unit in Rio Claro, made official with inauguration of SENAI Manoel José Ferreira in 1974, and the second Brazilian industrial wave (1968-1974). In order to investigate the veracity of such a hypothesis, bibliographic references were made about the evolutive history of Rio Claro industry and about the responsible manual work training agencies prior to SENAI being set up in the city, namely, the Professional School for Men of Rio Claro (1920) and the Railway Workers Course of Paulista Railway Network (1934). We resorted to a consultation of local legislation concerning SENAI Manoel José Ferreira , to the handling of manuscript and printed sources belonging to this institute, and to interviews with historical protagonists related to SENAI´s early years of work. By analyzing this whole intraining set, it was observed that, as happened with SENAI, the origin of the two institutions preceding this one, as regards preparation for technically qualified manual work for industrial purposes was also related to particularities of the industrial evolution of the city at the time of their appearances. It was also realized that being the fruit and the answers to distinct historical contexts, the three institutions had been guided by different pedagogic proposals that, when analyzed as a set, were a local representation of the change in the tendency of training of industry manual work, observed in Brazil during the 20th century. Then, the present work intended to establish a connection between the moment of the appearance of the referred institutions and the industrial evolution of Rio Claro, using as a guideline the growing transition from a tendency of industrial worker training of the craftwork kind to the rationalized-technical kind. The present undertaking was based, therefore, on the historical reconstruction that motivated the appearance of the three institutions in the city and on the analysis of the pedagogic proposal of these schools as far as their labor organization conceptions are concerned. The installation of the Professional School for Men of Rio Claro (1920) took place at a time in which the industrial-craftwork activities of the city were incipient, thus being proper for such the pedagogic proposal that affected the craft worker training. The rational principles of training for industrial manual work were introduced in the city by the Railway Workers Course of Paulista Railway Network (1934), which was implemented to meet the demand of the railway to broaden the reach of the scientific work administration policies, postulated by the Administration Reform of 1928. The appearance of SENAI in Rio Claro (1974), in turn, was actually tied into the features assumed by local industry after 1968, being responsible, therefore, for the extension of rationalized-technical training of the local industrial worker, beyond the railway field. During the period in which it was investigated (1963-1973) aspects regarding to structure, organization and functioning of the latter were identified - which were sorted out into periods according to the predominance of some features: Gestation (1963-1973), Introduction and Consolidation (1973-1975); Enlargement and Intensification (1976-1979) and Stagnation and Crises (1980-1985) and analyzed.

The release of carbohydrates by phytoplankton has been extensively studied because of its ecological significance. Bacterioplankton is a group of organisms that is able to use extracellular phytoplanktonic carbohydrates, as many authors have demonstrated. The aim of this thesis was to identify specific associations algae/bacteria in the planktonic environmental of a eutrophicated reservoir (Tiete river, Barra Bonita, SP), based on the carbohydrates released by the phytoplankton. The utilization pattern of such compounds was also studied. For this purpose, three phytoplanktonic species from Barra Bonita reservoir were used: Cryptomonas tetrapyrenoidosa (Cryptophyceae), Staurastrum orbiculare (Zygnematophyceae) e Thalassiosira sp. (Bacillariophyceae). The growth characteristics of these species in axenic conditions were determined and the extracellular carbohydrates produced by each one were characterized. Algae/bacteria cultivation experiments were performed inoculating the microbial community from Barra Bonita in axenic cultures of each algae. The phytoplanktonic growth pattern and the carbohydrate release were compared in axenic and contaminated cultures. From these algae/bacteria cultures, the specific bacteria community from each algae were isolated and they were re-inoculated in two kinds of culture media: composed by polysaccharides and low molecular weight released material. The bacterial diversity from the Barra Bonita reservoir was compared to the one observed in the algae/bacteria cultures and also in the two kinds of culture media, employing the DGGE method (Denaturing Gradient Gel Electrophoresis). The extracelullar carbohydrate production was exponentially increased at the stationary growth phase in the axenic cultures. The results showed clearly that the extracellular carbohydrates released by the phytoplanktonic species were used as an important carbon source to the bacterial populations, even when they occurred in very low concentrations (less than 1 mg/L). The polysaccharide utilization was remarkably distinct among the species under study. The results also showed that the polysaccharide degradations were not homogenous, but specific regions of them were degraded firstly. The results proved that the bacterial diversity patterns found in the Barra Bonita reservoir and in the different substrates were different. Specific bacterial populations were found as well as populations adapted to different classis of substrates.
