Bringing up the research problem. Along with asphalt processing activity comes the need for large yards for storing raw materials, which must be recovered when production ceases. With this problem in mind, this work aims to promote the recovery of an area degraded by its use in asphalt processing, located in an urban area of the Cerrado biome in Bahia, in the city of Barreiras-BA. The project will be executed applying four recovery techniques: seedling planting, direct seeding, natural regeneration, and artificial perches. Using different planting systems for the species, the efficiency of the recovery techniques used will be evaluated through monitoring of the area to be recovered. It is expected to highlight the most effective method for recovering degraded areas (RAD) in construction sites used for storing raw materials for asphalt processing in a territory whose biome is the Cerrado.

The Cerrado is the second largest biome in South America, constituting one of the areas with the greatest biodiversity of fauna and flora. Despite its rich biodiversity, the Cerrado is the most threatened biome in the country, with half of its area converted into agricultural land and planted pastures, making future research on native species with allelopathic potential unfeasible, many of which have not yet been studied. Since there are still few reports in the literature on the allelopathic potential of native species of the biome, understanding this is an essential strategy for reforestation and maintenance of its biodiversity, since seed germination and growth can be affected by allelochemicals released by neighboring plants. In this context, Myracrodruon urundeuva (Anacardiaceae) stands out, popularly called aroeira, aroeira-do-sertão or urundeúva, which is widely known in folk medicine. In addition to the occurrence of native species, cocoa (Theobroma cacao L.) has been planted in the Cerrado due to the need to increase the production of this commodity and the favorable soil and climate conditions. Thus, aiming to simulate the natural impact of leaf litter, the objective of this research will be to evaluate the allelopathic effect of the decomposition of senescent leaves of M. urundeuva, at different concentrations and decomposition times, on the initial development of T. cacao and Panicum maximum, an invasive species of this crop. For this purpose, senescent leaves of aroeira will be collected, dried at room temperature, crushed and added to the pots containing the soil, considering the following concentrations: 0, 10, 20, 30 g/kg. Then, seedlings of PS 1319 cocoa, aged 3 months, or seeds of P. maximum will be placed. To evaluate the allelopathic effect on cocoa, the following variables will be evaluated: root and shoot length, fresh root and shoot mass, membrane permeability, chloroplast pigment content and carbohydrate content. In the case of P. maximum, the following variables will be considered: emergence, emergence speed index, root and shoot length, fresh root and shoot mass. In addition, a physical-chemical analysis of the soil will be performed, as well as a leaf analysis, to determine the levels of micronutrients (Fe, Mn, Zn, Cu, Bo, Cl and Co) and macronutrients (N, P, S, K, Mg and Ca) present in the leaves. The data will be subjected to analysis of variance and the means compared by the Tukey test at a 5% probability level, using the SISVAR program. Therefore, it is expected that the research will support the implementation of cocoa cultivation together with M. urundeuva, which has the potential to establish beneficial interactions with the cocoa tree in order to contribute to the development of the crop in the Cerrado, as well as reduce the occurrence of P. maximum.

The present written work presents a planning proposal for a nature interpretive trail inserted within a context that seeks to implement Community-Based Tourism. This proposal continues the research developed during the undergraduate program in Geography at the Federal University of Western Bahia, which aimed to define the interpretive points of the trail based on participatory methodologies. Thus, the objective is to plan a nature interpretive trail as a mechanism for Environmental Education in the village of Penedo, located in the municipality of São Desidério, Bahia. Furthermore, it is intended to investigate the potential application of the principles of the Limits of Acceptable Change (LAC) to enhance trail preservation and to define how its structuring will be carried out in terms of the necessary operational resources, such as informational signs and maps. In addition, the aim is to develop didactic sequences and training itineraries based on the suggestions and demands identified within the local community. To achieve these objectives, the methodological approach adopted includes: bibliographic research based on books, scientific articles, and documents from local public agencies; data collection in the study area; the use of the Participatory Action Research (PAR) methodology; and the application of the Limits of Acceptable Change (LAC) system, with the purpose of determining the limits of acceptable alterations in the area.

Ensuring access to safe drinking water is crucial for promoting public health and human development. In light of this, this study evaluated the analytical coverage and compliance with drinking water quality standards of network-distributed water in the urban areas of the Western Bahia Regional Health Nucleus (NRS Oeste) in 2024, utilizing data from the Information System for Water Quality Surveillance for Human Consumption (SISAGUA). The research encompassed 36 municipalities distributed across the regions of Barreiras, Santa Maria da Vitória, and Ibotirama. The parameters analyzed were total coliforms, Escherichia coli, and turbidity, as well as the correlations among them and the seasonal influence on water quality. The relative analytical coverage was classified as optimal for all indicators (above 95%). Regarding water quality compliance in the NRS Oeste, total coliforms constituted the most limiting indicator (81.94% compliance), whereas turbidity (92.73%) and Escherichia coli (95.52%) demonstrated better alignment with current standards. Statistical tests revealed significant spatial asymmetry: Barreiras presented more robust results and effective treatment systems, even during the rainy season; Santa Maria da Vitória achieved considerable compliance, though mitigated by significant undersampling; and Ibotirama presented the most vulnerable scenario, concentrating the lowest potability rates and the highest seasonal sensitivity in Western Bahia.

This study analyzes state action in the possessory protection of traditional Fundo and Fecho de Pasto communities in Western Bahia, focusing on the case of the Capão do Modesto community, located in the municipality of Correntina. Based on an interdisciplinary approach that articulates elements from Human Geography, Law, and Environmental Sciences, the research investigates the relationships between territoriality, environmental identity, and land conflicts in a context marked by the expansion of agribusiness in the Cerrado biome. The study critically examines the effectiveness of public policies and legal instruments aimed at protecting these communities, considering the persistence of land grabbing, overlapping land registrations, and economic pressures on traditionally occupied territories. Methodologically, a qualitative approach is adopted, based on document analysis, literature review, and a case study. The central hypothesis is that state action has been insufficient to ensure effective possessory and territorial protection for these communities, contributing to the intensification of socio-environmental conflicts and vulnerabilities. The research aims to contribute to the debate on territorial justice, recognition of collective rights, and the preservation of the Cerrado biome.

 A busca por alternativas sustentáveis aos fungicidas sintéticos tem impulsionado o desenvolvimento de pesquisas voltadas ao uso de produtos naturais no manejo de fitopatógenos, visando reduzir os impactos ambientais e os riscos associados ao controle químico convencional. Nesse contexto, os óleos essenciais destacam-se pela diversidade de metabólitos secundários e pelo potencial biológico de seus constituintes. Assim, o presente estudo teve como objetivo caracterizar o perfil químico e avaliar a atividade antifúngica do óleo essencial de Artemisia absinthium cultivada no Cerrado baiano frente ao fungo fitopatogênico Fusarium oxysporum, bem como investigar, por meio de docking molecular, possíveis mecanismos de interação entre seus principais constituintes e proteínas-alvo do patógeno. O óleo essencial foi obtido por hidrodestilação de folhas coletadas nos períodos da manhã e da tarde e caracterizado por cromatografia gasosa acoplada à espectrometria de massas (CG-EM). A atividade antifúngica foi avaliada por ensaio in vitro, utilizando diferentes concentrações do óleo essencial, e os dados foram submetidos à análise de variância e ao teste de comparação de médias. O rendimento do óleo essencial foi de 0,45% para as folhas coletadas no período da manhã e de 0,26% para aquelas coletadas à tarde. A análise cromatográfica revelou predominância de monoterpenos oxigenados, com destaque para os isômeros de tujona, que constituíram os principais compostos do óleo essencial em ambos os períodos de coleta. No bioensaio, todas as concentrações avaliadas promoveram completa inibição do crescimento micelial de F. oxysporum, apresentando desempenho estatisticamente equivalente ao fungicida comercial utilizado como controle positivo. As análises de docking molecular indicaram interações energeticamente favoráveis entre os isômeros de tujona e as enzimas quitina sintase 2 e 1,3-β-glucana sintase, sugerindo que essas proteínas podem representar potenciais alvos moleculares dos principais constituintes do óleo essencial. Os resultados demonstram que Artemisia absinthium apresenta elevado potencial como fonte de compostos naturais para o desenvolvimento de estratégias sustentáveis de manejo de fitopatógenos, integrando evidências químicas, biológicas e computacionais que reforçam sua aplicação como candidata promissora ao desenvolvimento de biofungicidas.

Dimorphandra mollis (false barbatimão) is a tree species native to the Cerrado biome, exploited for the rutin extracted from its fruits, necessitating studies on its propagation for conservation purposes. This study evaluated the effect of growth regulators on the rooting of cuttings and the influence of light availability on the sexual propagation of D. mollis. For propagation by cuttings, apical herbaceous cuttings were collected from mother trees, and their bases were immersed in solutions of indole-3-butyric acid (IBA), a commercial biostimulant (Stimulate®), and an aqueous extract of Cyperus rotundus (EAT). After 90 days, survival (%), rooting (%), and sprouting (%) were assessed. In sexual propagation, seeds were sown in tubes containing Cerrado soil and subjected to different shading levels: 0% (full sun), 30%, 50%, and 80%. Seedling emergence and the Emergence Speed Index were monitored daily, and after 90 days, seedling height, number of leaves, collar diameter, root length, total chlorophyll content, and fresh and dry biomass of both the root system and aerial parts were analyzed. The tested growth regulators did not stimulate root formation in the cuttings and are not recommended for this purpose. However, seedlings grown under 50% shading showed higher emergence, IVE, growth parameters, and biomass accumulation, indicating that this condition favors the initial growth of D. mollis.

maiores problemas trazidos ao nosso Cerrado.

The final disposal of municipal solid waste in sanitary landfills is a relatively recent practice in Brazilian geotechnical engineering. In this context, geotechnical monitoring of these structures is essential to ensure structural safety, environmental protection, and to advance the understanding of waste behavior. This study aimed to analyze the geotechnical behavior of a sanitary landfill located in the western region of Bahia State, Brazil, using unmanned aerial vehicle (UAV) photogrammetry and comparing it with conventional topographic surveying. The research focused on the vertical and horizontal displacements of the waste mass, the analysis of slope stability, and their correlation with local rainfall. The methodology involved acquiring topographic data through conventional leveling and UAV photogrammetry, allowing the validation of UAV-derived survey accuracy. During the construction phase, the unit weight of the waste was assessed by volumetric analysis of disposal cells, comparing field data with photogrammetric estimates. In the post-construction phase, vertical and horizontal displacements were monitored over successive campaigns, including the determination of displacement rates. Additionally, slope stability simulations were performed considering geotechnical and rainfall parameters. The results indicated that UAV photogrammetry achieved accuracy comparable to conventional leveling, validating its application in landfill monitoring. The average unit weight of the waste varied according to the filling stage, reflecting the degree of compaction achieved. In the post-construction period, vertical and horizontal displacements were influenced by rainfall intensity, allowing the identification of variations in settlement rates over time. The slope stability simulations demonstrated that rainfall has a direct effect on reducing the safety factor, highlighting the need for adequate drainage strategies. It is concluded that UAV photogrammetry is an effective alternative to conventional leveling, offering advantages in terms of coverage and operational efficiency. Furthermore, the observed correlation between rainfall and geotechnical behavior reinforces the importance of integrating local climatic variables into landfill planning and management. The study contributes to the improvement of monitoring techniques for small- and medium-sized landfills, providing technical insights for their safe and sustainable operation

Due to use and occupation of Cerrado areas, it is necessary to develop propagation
techniques for native species, such as Copaifera depilis, in order to guarantee the
conservation of the flora, as well as understanding how they interact in the
environment. In this context, this work aimed to evaluate the efficiency of cuttings and
layers, using different concentrations of indole-3-butyric acid (IBA), and of seminiferous
propagation associated with the use of gibberellic acid (GA3) in the production of C.
depilis seedlings,in addition to evaluating the allelopathic effect of leaves supplied on
the soil surface on the initial development of corn. In propagation by cuttings, they were
immersed in the following IBA concentrations (0, 800, 1600, 2400, 3200 mg /l). After
120 days, the following were evaluated: number of rooted cuttings, average number of
roots/cutting, average length of the three largest roots, mortality and stems formation.
In layering propagation, the layers were soaked in different IBA concentrations: 0, 500,
1000 and 1500mg/L. After 180 days, the following were evaluated: The rates of air
layering rooting, root/air layering, largest root length/air layering, stem formation and
shoots survival. In propagation via seminifera, a group of seeds was scarified and the
other was not, with all seeds immersed in GA3 for 24 hours, at concentrations of 0, 50,
100, 200 and 400mg/L. After 80 and 160 days, the following parameters were
analyzed: height, stem diameter, number of leaves and relative chlorophyll
content.After 160 days, the experiment was completed and the plants were separated
into the roots and top of the plant to determine fresh and dry mass. In allelopathic
experiments,dry leaves were used and found on the soil surface at concentrations of 0,
1, 2, 4, 6 and 10t/ha.After 30 days, a destructive analysis was carried out and the
following growth characteristics of the corn plants were evaluated: root, the aerial part
of plant, diameter, number of leaves, relative chlorophyll content of the second and
third leaves, fresh and dry mass of the leaves, root and aerial part. The data were
subjected to analysis of variance and the means were compared using the Scott-Knott
test, at a 5% probability level.The results obtained that propagation by cuttings and
layering are not viable for C. depilis, with 100% mortality of cuttings and layering,
respectively.Regarding seminiferous propagation, it was observed that there was no
significant effect of scarification and GA3 for the following characteristics: emergence,
height, stem diameter, number of leaves, relative chlorophyll content, size of the
smallest leaf and root size.Unlike other characteristics, there was a significant effect of
scarification, which promoted an increase in the size of the largest leaf, fresh mass of
the seedling, root and aerial part and dry mass of the seedling, root and aerial
part.For allelopathic activities, C. depilis leaf extracts showed potential, negatively
interfering in: emergence (4, 6 and 10t/ha), height (all concentrations), stem diameter
(6 and 10t/ha), fresh mass of seedling (6 and 10t/ha), the aerial part (2, 6 and 10t/ha)
and the root (6 and 10t/ha), in addition to the dry mass of the seedling (6 and 10 t/ha),
aerial part ( 2, 4, 6 and 10t/ha) and root (2, 4, 6 and 10t/ha). It is concluded that
propagation via semifera is efficient for the production of C. depilis seedlings, based on
the physical scarification of the seeds, and that the leaf extracts have allelopathic
potential, with a reduction in the growth of the model species (corn), demonstrating
potential for use as a natural herbicide, which requires experiments with spontaneous
plants.

The western region of the state of Bahia, which was naturally occupied by the Cerrado, has now been appropriated by agribusiness and has become one of the main areas for the expansion of the country's agricultural frontier, with an emphasis on grain production. One of the aims of the West-East Integration Railway (FIOL) in western Bahia is to transport agricultural products from the region. Since anthropogenic action is responsible for a number of changes to the environment, this study aims to assess the main environmental impacts of the construction of the FIOL in the geraizeira community of Vereda Grande, in the Guará river valley, in São Desidério-BA. Based on the aspects of FIOL's implementation activities in the geraizeira community in question, the aim is to quanti-qualitatively analyze the main environmental impacts that have interfered with the environmental and territorial dynamics of the region, as well as to understand the environmental perception of the Geraizeiros in relation to these possible impacts. To carry out this research, the methodological procedures adopted were bibliographical research, documentary analysis and exploratory fieldwork, with direct observation and the application of questionnaires and semi-structured interviews.

Artibeus lituratus is an important neotropical frugivorous bat species belonging to the family Phyllostomidae. Despite its widespread distribution, there are no detailed reproductive studies on the mammary glands of this species. Thus, the aim of this study was to analyze and characterize the histology and hormonal regulation of mammary glands and ovaries of Artibeus lituratus during reproductive phases. For chapter one, twenty sexually mature females were collected and divided into 3 sample groups according to reproductive status (non-reproductive, advanced pregnancy, and lactating), and for chapter two, thirty sexually mature females were collected and divided into 6 sample groups according to reproductive status (non-reproductive, early pregnancy, mid-pregnancy, late pregnancy, lactating, and pregnant lactating) and subjected to anatomical, histological, morphometric, immunohistochemical (ERα, PR, PCNA, P63, α-actin, LHR, and FSHR), and serum assays for progesterone, estradiol, follicle-stimulating hormone, and luteinizing hormone. The results demonstrated that the mammary glands of A. lituratus are lateralized and exhibit a morphology very similar to that described for mammals, consisting of simple cuboidal epithelium, connective tissue, and adipose tissue. The action of hormones progesterone via PR and estradiol via ERα coordinates the entire development and differentiation of secretory epithelium during advanced pregnancy and lactation. All data indicate that A. lituratus possesses promising characteristics, and in the future, it can be used as an experimental animal for mammary gland studies. In the ovaries, the results showed that serum concentrations of FSH and LH are constant and minimally variable among the groups. The action of these hormones on the ovaries of A. lituratus creates a highly interactive microenvironment, with the development of follicles in different stages. The majority of ovarian structures respond to LH and FSH. The Theca, granulosa, and stroma exhibited greater variation in FSHR and LHR expression, while the corpus luteum expressed them in all cells from early to late pregnancy. There was no dominance in receptor expression among the ovaries of A. lituratus.

Brazil stands out as a country of remarkable biodiversity, with impressive richness in terms of species count and the complexity of its biomes. Among these, the Cerrado biome excels due to the diversity of its landscapes, flora, and fauna. Among the countless species present in the Cerrado, we can mention Salacia crassifolia (Mart. ex Schult.) G. Don., commonly known as bacupari, cascudo, or saputá, which holds significance due to its multiple uses, including culinary, medicinal, and landscaping purposes. Since ancient times, the properties of plants have been harnessed for various purposes, including the search for alternatives to control phytopathogens through plant extracts containing secondary metabolites with potential antifungal properties. Despite the studies already described, there is a gap in research regarding the antifungal potential of the species in question. Hence, there is a need to investigate the antifungal activity of extracts from native plants of the Cerrado, aiming to identify and comprehend the secondary metabolites with such properties. This is a pioneering study in assessing the effects of stem bark and leaf extracts of S. crassifolia, as the species lacks studies directed at the activity of phytopathogenic fungi in relation to its ethanol extracts. With the objective of identifying and evaluating the phytochemical profile and activity against phytopathogenic fungi of the leaf and stem ethanol extracts of Salacia crassifolia, samples of bark and leaves were collected from two matrices located in the rural area of the Western Bahia Municipality. To determine the phytochemical profile of the extracts (EES and EEL), the methodology proposed by Barbosa and colleagues (2001) was employed. Regarding the assessment of the extract's effect on mycelial growth, a randomized bioassay with four repetitions was conducted, using an experimental unit consisting of three Petri dishes. The results of this study offer new perspectives concerning the utilization of S. crassifolia as a potential source of substances with antifungal properties.

The collection, direct use and commercialization of native flora resources are activities
practiced, above all, by traditional communities, linked to sociocultural, identity and
economic issues. The removal of parts of plants for medicinal and woody use and for
agro-industries is a practice that is very present in the Cerrado of Western Bahia,
practices that are intrinsic to the cultural formation of these places. However, with the
increase in commercial demand for extractive products, exploitation may be carried out
inappropriately, causing, in some cases, a significant reduction in natural populations of
the species used. In this sense, this work aims to evaluate the effect of extractive
activities on the structure and organization of populations and natural communities and
point out indicators for the construction of a sustainable management protocol for
extractive species. Specifically, this work aims to ecologically characterize the native
species Dimorphandra mollis Benth, a focus of extractivism, with potential for
commercialization of non-timber products, used by the rural community of Almas. To
this end, the characterization of the structure and productivity of populations in natural
communities, the structure and productivity of populations in extractive areas, as well as
the phytosociological attributes of these populations within the aforementioned systems
were considered as ecological attributes. Furthermore, the objective was to characterize
the landscape surrounding the extractive areas, considering relevant aspects, such as:
presence and phytophysiognomic identity of forest fragments, human occupation, direct
area of operation of the West East Integration Railway (FIOL) and other projects. From
this perspective, extractivism is a common activity in the areas of influence of FIOL
works in São Desidério and this work assumes crucial relevance with regard to the
characterization of sustainable extractivism activity, and can, therefore, be a focus
activity for compensation projects environment that value local cultural practices. The
research was carried out in the community of Almas, belonging to the municipality of
São Desidério, Bahia, local extractivists. Data collection on populations of native
species in the Cerrado of Western Bahia was carried out by establishing continuous
plots in the areas of influence of the communities (extractive areas and control areas),
based on phytosociological analysis, NDVI (Index of Vegetation by Normalized
Difference) and morphometric parameters of fruits. It was found that extractive activity
interferes with the structure and forest composition of the Cerrado area, presenting
results of phytosociological parameters with significant differences between areas. The
landscape analysis showed a marked difference between the areas, indicating that
extractive activity contributes to the structural disconfiguration of the landscape with
dominance of D. mollis to the detriment of low floristic diversity in the sampled
fragment. Furthermore, significant differences were observed in morphometric variables
and fruit production of D. mollis between areas. Based on the ecological indicators
evaluated in this work, it was possible to develop a protocol of good management
practices to benefit both the extractive activity and the focus species, based on
suggestions for potential strategies to promote and/or accelerate the area's restoration
process. in natural regeneration.

Every year, tourism is responsible for transporting millions of people between diferente
locations on the planet, seeking leisure, entertainment and visiting various attractions.
Its implementation has great complexity and relevance in aspects, highlighting the
socioeconomic aspect, as it encompasses public and private investments, which seeks to
generate revenue, jobs and income in the various locations in which it is carried out.
Planning around its development is necessary, carried out primarily by everyone
involved in its practice. Given the context, Brazil and Bahia have been developing
public policies over time with the intention of categorizing, organizing and managing
tourist areas in their respective territories. Both adopted the concept of a tourist region,
comprising a set of municipalities with an interest in the development of tourist activity
based on one or more historical, cultural, economic and/or geographic characteristics.
Base for implementing the Tourism Regionalization Program (PRT), within the scope of
the National Tourism Plan (PNT). At this juncture, the Caminhos do Oeste tourist
region was created in 2004, currently made up of eight municipalities, namely:
Barreiras, Bom Jesus da Lapa, Caetité, Correntina, Cocos, Formosa do Rio Preto,
Jaborandi and São Desidério. In view of the above, the present work aims to diagnose
the socioeconomic implications promoted by the institutionalization and development of
tourist activities in Caminhos do Oeste. The research is exploratory and descriptive,
with a qualitative approach, carried out in two stages: Literature review for theoretical
contextualization about tourism and tourist regionalization, identification and analysis
of legal instruments related to its planning, institutional organization and public policies
in the country focused on the theme and the historical, environmental, socioeconomic,
infrastructure and territorial characterization of the study area; Construction of the
institutional and socioeconomic profile of the Caminhos do Oeste tourist region,
through the identification and characterization of the legislation and institutionalization
of tourism in the municipalities that make up or comprised the tourist region and the
survey, systematization and tabulation of secondary data to present related
socioeconomic indices tourism in the state, regional and municipal context. It was
identified that between 2004 and 2022 there were six changes regarding the number and
municipalities that made up the tourist region in the different PRT publications during
this period. At the state level, Caminhos do Oeste presented modest socioeconomic
results, especially when analyzing their participation in the total revenue from ACTs
and the contribution of formal jobs. Among the municipalities, in addition to the
diversity of tourist attractions, different realities were identified regarding
institutionalization and socioeconomic gains arising from the tourist activity carried out
in them. To make better use of the tourist potential of Caminhos do Oeste, it is
recommended that COMTUR participate more effectively in carrying out the study on
the tourism situation in the respective municipalities; engagement of all sectors linked
to the efficient operation and development of tourism in the region, thus providing
tourists with a quality activity based on tourism that prioritizes sustainability, but
without neglecting the profitability that the activity can provide to those involved and/or
service providers. services in these municipalities.

Floral symmetry is a remarkable feature impacting both pollination ecology and floral biology, symmetry patterns (asymmetry, monosymmetry, dissymmetry and polysymmetry) are often associated with pollinator flight orientation and, at least partially, in directing pollen movement to pollinator bodies. Despite their relevance in plant biology and their fundamental role in the evolutionary dynamics of flowers, few studies have provided quantitative characterizations of floral forms and their symmetry patterns, so little exploring these structures in an evolutionary context. This is the case of the diverse genus Chamaecrista, which presents pollen flowers, pollinated exclusively by bee vibration, the flowers in general are asymmetric with the presence of a modified petal - cucullus. Comparative studies for the genus, including investigations of floral symmetry in an evolutionary context are lacking.  Thus, our main objective was to characterise floral diversity quantitatively, analyse how this diversity is distributed in the genus and observe how it is correlated and conserved throughout its evolutionary history.. For such, 115 species were analysed by images and/or exsiccata, of these 71 (three individuals per species) were dissected and later analysed for the description of the floral symmetry planes, and in the morphometric analysis for the floral forms and the cucullus (Fourier Elliptical Analysis - FEA). Moreover, to evaluate the evolutionary correlation, conservation and distribution of the characters and their phylogenetic significance, the PGLS (Phylogenetic Generalized Least Squares) model, the Phylogenetic Signal and Ancestral character estimation for the continuous characters were implemented, respectively. . We found eight symmetry patterns for Chamaecrista corolla morphology, predominantly asymmetric. Although, there was not a strict correspondence between the shapes, considering that some patterns appeared more than once in different clades, we noted that species of the same clade, in general, tend to group together. The evolutionary correlation analysis was not significant, however, both shape and size are conserved in certain lineages and had a significant phylogenetic signal.  Here, we characterised, classified and explored the floral symmetry of Chamaecrista from a phylogenetic perspective. We observed a diversity of symmetries across the genus, and detected conservatism of floral shape and size throughout phylogeny, indicating a possible relationship with pollinator-mediated selective pressures, as suggested in the literature. However, studies in floral biology, development of structures and detailing of other organs (e.g., gynoecium and androecium) are still needed to better understand the processes involved in the patterns described here.

The herbivorous insects are highly specialized because they have the ability to control and
redirect the development of host plants to obtain food and shelter. These insects induce the
formation of branches that are tissue cells or plant organs that present abnormal growth, and
may be formed by hyperplasia or hypertrophy, in response to the action of cecidogenic agents.
The distribution of the galls in plants can be influenced by seasonality and phenological events,
which will determine the reproductive success of the chickens. The species Manihot
caerulescens Pohl presents a diversity of insects that induce chickens that are still incipient in
the Cerrado of West Bahia. In this context, this work aimed at (1) getting to know the fauna
associated with the branches of the species M. caerulescens and (2) relating the presence of
branches with the phenological events of the host plant species and climate variables. In order
to achieve the objectives, 24 monthly collections were made between the months of July 2018
and June 2020, at Serra da Bandeira, located in the city of Barreiras-BA. For characterization
and analysis of the branches 5 leaves were randomly collected from each host plant, totaling
180 leaves, and also 1 inflorescence per plant, totaling 90 inflorescences. The gallop material
was transported to the laboratory for sorting and morphological analysis of the branches. The
insects obtained were mounted on slides and used in morphological studies. For the
phenological characterization of the species under study, the marked individuals were observed
on a monthly basis, and the phenological and vegetative phenophases were recorded,
photographed and analyzed. The results showed that Iatrophobia brasiliensis has preference on
the induction of galls on the leaves or inflorescences, a behavior not registered for this species
of cecidomyid. The associated fauna was composed of tenants, parasitoids and successors. The
infestation by galls presented greater occurrence in the dry season. Regarding the vegetative
and reproductive phenological events in M. caerulescens it was verified that the percentage of
individuals with leaves, shoots and fruits was higher in the rainy season, while flowering in the
dry season. In this context, this work constitutes an important contribution to the knowledge of
the diversity patterns of Manihot, as well as of Iatrophobia in the Cerrado of Bahia.

Red ceramic waste (RCW) from the construction industry is still a problem to be addressed at national level. Uneven disposal of this material generates serious environmental problems. However, research has shown that the use of RCW, in an adequate fineness, may present pozzolanic characteristics, making it possible to use it as a mineral addition to Portland cement in partial replacement to clinker. In view of the above, this research aims to verify the pozzolanic potentiality of the red ceramic waste from pottery located in Riachão das Neves / BA, comminuted in particles smaller than 45μm for partial replacement of Portland cement type CPV ARI RS, in the content. 30% by mass and the effects of the use of this residue on sulphate attack performance. The steps taken to fulfill this objective include: the physicochemical characterization of the red ceramic residue; determine the pozzolanic reactivity of the residue by the Modified Chapelle Method; the pozzolanicity assessment of the replacement of 30% by weight of cement by RCW by the Fratini Test; reaction kinetics of cement pastes with 30% replacement by RCW, with emphasis on the determination of portlandite consumption and apparent porosity variation of pastes over 182 days; the effects of replacing 30% of cement by RCW on mortars in the water / binder ratio of 0.35; 0.45 and 0.55 in the evolution of compressive strength and apparent porosity and also verify the performance of RCW in mitigating the sodium sulfate attack in mortars. The RCW had an average consumption of 907 mg of Ca(OH)2 / g. The partial replacement of 30% by mass of cement by RCW attributed pozzolanicity to non-pozzollanic cement. The X - ray diffraction and thermogravimetry assays in 30% RCW pastes showed a consumption of Portlandite over time, indicating pozzolanic activity. The 30% RCW mortars submitted to the axial compression test presented inferior performance in all ages and water / agglomerates ratios when compared to their peers without substitution. The use of RCW provided the mortars a superior performance when submitted in an aggressive environment

The recent accelerated and disorderly urban growth of the city of Barreiras (BA), caused by the advent of agribusiness and the consequent migrations, together with the large appropriation of areas more suitable for housing by the real estate market, creating the so-called real estate speculation, the population of the city to the occupation of areas whose geology and geomorphology are unfavorable. They are places that, before being anthropized, would require a study on the morphological characteristics of the land, but whose appropriation was given without adequate infrastructure, especially with regard to urban drainage, land use and land use planning and adequate stabilization of the slopes, causing populations in these areas to be at constant risk, and thus susceptible to natural disasters, such as mass movements and floods. One of the most significant examples of this reported process is the set of neighborhoods created on the slopes of Serra do Mimo. According to the Urban Development Master Plan (PDDU) of the city of Barreiras, the Serra do Mimo is considered as a zone of controlled occupation, but has been heavily occupied without any concern or technical study of the problems that may occur, or even about possible solutions. This work seeks to study the consequences of urban sprawl in the neighborhood near the Mimo Mountains, seeking to understand the social and environmental implications of this occupation, done without planning, even with the consent of the municipality.

The inventory of conidial fungi associated with decomposing plant substrate was carried out in two areas of extreme importance for biological conservation within the Caatinga biome, in the region of Middle São Francisco, in the state of Bahia. Aiming to increase the biodiversity of conidial fungi collected, collections were made in the period starting from October/2016 to February/2017, covering the dry and the rainy season in the region. Leaves, branches, flowers and fruits were collected encompassing wide variety of material, in soil and submerged in rivers and ponds. The collected material was submitted to the washing in flowing water technique and plating in a moist chamber. For 21 days, the observation and collection of the reproductive structures of the conidial fungi were carried out under the stereomicroscope using a fine-needle and mounted on permanent blades in PVL resin mounting medium. The results are described in two chapters. In the first one, the biodiversity of conidial fungi collected in land litter is presented, resulting in nineteen species collected, whereas two of them are considered new records for the state of Bahia, Neta quadriguttata (Matsush.) de Hoog and Phialophora verrucosa Medlar. In the second chapter, the fungi collected in submerged litter are described, among the eighteen species collected, Dactylaria plovercovensis Goh & K.D. Hyde. was first recorded in America, Dictyochaeta coffeae (Maggi & Persiani) Whitton, McKenzie & K.D. Hyde. was first recorded in Brazil, and Falcocladium multivesiculatum S.F. Silveira, Alfenas, Crous & M.J. Wingf. was first recorded in Bahia. Thirty four species of conidial fungi were identified. This research expands the knowledge of the diversity of conidial fungi for the middle São Francisco.
