Landscape fragmentation compromises biodiversity and ecosystem connectivity. This study modeled restoration scenarios based on Payment for Ecosystem Services programs, aiming to integrate environmental benefits. Restoration scenarios were analyzed using low natural agricultural suitability areas currently covered by pastures within rural properties in the Vale do Paraíba Paulista, São Paulo, Brazil. Using land use data and geographic information system tools, two restoration scenarios were modeled. The integral restoration scenario, which included all restoration areas, increased forest cover by 27.35% and average connectivity by 31.85%, connecting fragments and creating new habitats, with 134,498 hectares restored. The partial restoration scenario, focusing on selected restoration areas, increased forest cover by 72,182 hectares, prioritizing the expansion of fragments larger than 60 hectares, boosting average connectivity by 26.82% while optimizing resources. Both scenarios increased areas with very high connectivity and reduced areas with very low connectivity, with the most significant differences observed in intermediate connectivity classes. The study highlights that restorations facilitated by Payment for Ecosystem Services programs can reduce fragmentation and enhance regional sustainability, providing a basis for public policies that align biodiversity conservation with climate change mitigation

This dissertation is about memories of a social worker from Espírito Santo. The author uses the process of a trip as an analogy, associating the research elements with items such as maps, itineraries, luggage and photographs. She had multiple encounters and interactions during her Multiprofessional Residency with the Brazilian Unified Health System (SUS). She researched the local challenges in management and care for people in severe psychological distress. The author was encouraged by the recently created school of public health in the State of Espírito Santo - ICEPi - Instituto Capixaba de Ensino, Pesquisa e Inovação em Saúde, to broaden her professional knowledge by furthering her professional experience in another academic setting as well. She pursued the Professional Master Degree in Clinical Management at The Federal University of São Carlos (UFSCar-SP). In a clear, deep, engaging and provocative way, the researcher sought to understand and analyze the perception of resident professionals who attended ICEPi's Multiprofessional Residency Program in Mental Health (PRM-SM) between March 2021 and February 2023. Its focus was the development of attributes for the competence of collaborative interprofessional practice in the SUS. In a diverse and innovative linguistic proposal, the author organized a qualitative, descriptive, and exploratory research, broadly intersected by narrative resources. She used a narrative method for her data collection instrument, and presented her writing according to scientific standards. Based on a brief survey, the study entailed the forming of critical, reflective narratives which were created individually by the residents participating in the research. It was followed by integrating these discourses into a single synthesized narrative which was validated by the collection itself. Based on this data and anchored on theoretical references of Health Care, Multiprofessional Residencies in the SUS and Interprofessional Education, the author identified three thematic axes: Education-Teaching, Work-Service, and Care-Community. She merged the data in three areas of perceptions: representations, learning, and contributions. Guided by hermeneutic-dialectic analysis, the researcher revealed potentialities and gaps in training. She pointed out that the PRM-SM has contributed to the development of a collaborative interprofessional practice in the SUS, and the need for complementary scientific research should be carried out in order to affirm the real effectiveness of the Program for Interprofessional Education for the SUS. The findings of this research also identify that interprofessionality would be enhanced through education and training because it sustains, reinforces, and consolidates the work and care processes expected through the SUS. In a poetic and philosophical closing, the author uses the short story by Zadig, “Destiny”, written by the French enlightener Voltaire. By demarcating its implications in work and life, the researcher calls us to a final reflection: it is urgent to rescue the essence of our human identity, whose realization is both unique to the individual and integrated with his/her community.

This doctoral thesis addresses the research problem: "How can music recommendation systems be improved to more effectively integrate interaction context and user experience?". In response to this question, the research develops and evaluates UConteXt Arch, an architecture for music recommendation systems. This architecture is designed to enhance the user experience, explicitly considering the interaction context and musical preferences. The methodological approach adopted is Design Science Research (DSR), which enables iterative and cyclical analysis in the development of UConteXt Arch. The architecture is based on theories and research into recommendation systems, user experience, and contextual personalization. The development of UConteXt Arch involved a systematic literature review and exploratory studies of current practices on platforms such as Spotify and Deezer. The evaluation of UConteXt Arch included a variety of methods, such as the Communicability Assessment Method (MAC), the Technology Acceptance Model (TAM), UX Curves, and the Method of Intermediate Semiotic Inspection (MISI). These methods confirmed the effectiveness of the architecture in delivering accurate and adaptable music recommendations in line with changing user preferences and contexts. The architecture also addresses the ``cold-start'' challenge by implementing immediate feedback mechanisms and continuous learning to improve recommendations. The thesis concludes that UConteXt Arch represents a solution to the identified problem, demonstrating that it can significantly improve music recommendation systems by more effectively integrating interaction context and user experience. This study helps improve the quality of music recommendations and enriches the user experience, making a substantial contribution to the field of music recommendation systems.

The central aim of this thesis was to identify, describe and understand the educational processes that emerge from the social practice of ceramic creation carried out by female ceramic artisans in the Alto Vale do Ribeira. This region is located in the largest continuous area of Atlantic Forest preservation in Brazil. In the midst of this place, the ceramic practice has been carried out according to techniques passed down between generations in rural neighborhoods, retaining in the different characteristics of the activity ancestral indigenous and quilombola teachings, which have validated its production, as well as presenting characteristics that demonstrate its peculiar and expressive improvement supported by the individuals' own taste. Despite the contemporaneity of popular creation and the appreciation of each cultural universe, we understand that artistic creation as a symbolic expression of human beings reveals meanings related to aesthetics, but also the values of individuals and groups in the social practices they experience. Considering the practices of popular groups as a field of research that generates relevant educational processes in the shaping of identities, values and attitudes goes hand in hand with recognizing that the historical production of human beings is supported by their perception of their time-space, and that it is concretized to the extent that they objectify it, in other words, they integrate it and produce and reproduce themselves in it through the senses and meanings elaborated in their experience of the world. We therefore turn to this ceramic social practice, with the aim of finding the dimensions that can strengthen the notions of the links between creation and tradition in this place. This is a qualitative study based on phenomenology, the situated phenomenon modality. Interviews were carried out to collect data, using photographs taken by the researcher during the ceramic production activities of the potters from the Alto Vale do Ribeira. From the analysis of the data, two categories of educational processes were obtained: A) "Do you want to make clay pots with me?" centered on the ceramicists' memories and experiences that have shaped their life trajectories of encountering the ancestry of ceramic making; B) "I really like working with clay", referring to the principles that legitimize the practice of ceramic creation in the popular work with clay, which affirm social identities while expressing and renewing their collective meaning. Among the educational processes revealed, we can highlight the role of ancestry in each artisan's relationship with the context, as well as the strengthening of notions of otherness in ceramic making in their intrinsic ability to learn-by-doing with each other by valuing what is specific to their cultures. Faced with different challenges in order to keep going, potters have shown that solidarity, respect, collaboration and cooperation are elements of this social practice.

Energy dissipation in systems, such as solid-gas and solid-liquid, can occur in several ways, including resistance to motion, interfacial interactions, deformation, and particle collision. In gas-solid flows, the main energy dissipation occurs due to plastic deformation, internal friction or elastic losses during interactions between particles or between particles and surfaces. On the other hand, in liquid flows, factors such as surface tension, adhesion and dissipative forces are relevant. One of the ways to measure this dissipation is by measuring the restitution coefficient, a dimensionless coefficient given by the ratio between the restitution and impact velocities. In liquids, this parameter is also related to the liquid's ability to dissipate energy during a collision and is called the effective coefficient of restitution. The study of this dissipation is crucial to understanding system behavior, optimizing processes, and designing efficient devices. In this context, this work aims to investigate the various factors involved in collisions that affect the restitution coefficients and the effective restitution coefficient. To this end, commercial particles of ABS, porcelain, carbon steel (coated or not with a polymeric film), polypropylene and high alumina were characterized in terms of density, diameter and Young's modulus and used in experimental particle-surface collision tests. In tests in air, the results showed a decreasing trend in the coefficient of restitution with the increase in the number of successive impacts in collisions and the ratio of particle diameter/thickness of the collision plate. Furthermore, the influence of material properties on the restitution coefficient values was observed, including the effect of a polymeric film covering carbon steel spheres. In liquid experiments, effective restitution coefficient results were obtained at different concentrations of glycerin solution, and a directly proportional relationship was observed between the increase in this parameter and the Stokes number. Finally, experimental data from the literature were used to validate a proposed correlation for predicting the dry restitution coefficient as a function of particle properties, wall thickness and impact velocity. The results demonstrated that the correlation satisfactorily described the experimental data and proved to be an effective tool in predicting this parameter.

The golden-headed lion tamarin (Leontopithecus chrysomelas) (Kuhl, 1820) belonging to the family Callitrichidae is a New World primate that is classified as endangered in the wild. Leontopithecus chrysomelas is an endemic species of the Atlantic Forest occurring in forest remnants and cabruca areas of Bahia. Due to loss, fragmentation and disconnection of habitat, the species is in population decline, requiring studies and actions aimed at its preservation. The identification of diseases that affect New World primates is of great importance in public health and in situ and ex situ conservation programs, due to the risk of anthropogenic influences creating conditions for infectious diseases to decimate entire populations of wild animals. Therefore, the investigation of diseases in these animals is of great relevance for conservation medicine and for the purposes of One Health. A retrospective survey of the clinical case series and deaths involving individuals of Leontopithecus chrysomelas from the São Paulo Zoo was carried out from January 2016 to July 2023, through the analysis of medical records, findings from clinical/physical, hematological, histopathological examinations, ultrasonographic and necropsy findings, to evaluate the case series, clinical manifestations and diagnoses. The data was spreadsheeted and the changes analyzed. Thirty-eight individuals were treated by the Veterinary Medicine Sector at the São Paulo Zoo, in a total of 196 care carried out. Nineteen deaths occurred during the period under study. Although hepatic/hepatobiliary disease/hepatic failure was the most evident clinical case during the consultations, and several of the animals presented gallstones and/or hepatic neoplasia, in the final diagnoses (histopathological examination after necropsy) and cause of death the most common disorders affected the renal system.

In Brazil, according to data from the National Household Sample Survey (PNAD - Continuous) in 2022, 56.1% of Brazilians identified themselves as Black (black/brown). According to data released by the Brazilian Institute of Geography and Statistics (IBGE), at least 18.6 million Brazilians have some type of disability. This research, based on a documentary and microdata analysis, which, according to Triviños, is a descriptive study. Its objective was to analyze, based on national educational indicators, the entry of the Black and/or disabled population into Brazilian higher education in the year 2022 and the developments following the promulgation of Laws No. 12,711/2012. Concluding that it is necessary to gather this population for the construction of policies that make sense in the integration of these individuals regarding overcoming barriers imposed by capitalist society, which hinder these subjects, whether due to structural racism or discrimination based on body differences. This is to enable continuity in legislation such as the Quota Law.

The objective of this research was to understand the profile of indigenous medical students, their historical trajectory, and experiences related to their persistence in the institution. A quantitative-qualitative research approach was employed. The study involved mapping the indigenous students who entered from 2007 to 2023 using institutional documents. Individual contact was made through social media and phone calls, inviting them to participate in the research. Fifteen indigenous students who entered through the supplemental slot were identified. Twelve participants were included in the research, utilizing questionnaires, individual interviews, and group discussions.Over the 16 years of affirmative actions, 15 indigenous students entered the medicine program through the supplemental slot, and no indigenous students were admitted through Law No. 12,711/2012, which establishes quotas in federal universities. The entrants ranged in age from 17 to 42 years, with 10 men and 5 women, including three with children. In terms of origin, 9 were from Pernambuco, 2 from the Amazonas, 2 from Espírito Santo, 1 from Acre, 1 from Alagoas, and 1 from São Paulo. They represented various indigenous groups, including Pankará, Jeripancó, Xucuru de Cimbres, Huni-Kuin, Tikuna, Tariano, Tupinikim, Pankararu, Atikum-Umã, and Xucuru de Ororubá. Six of the entrants completed the program, 6 are currently in the undergraduate program, and 3 withdrew before graduating.Based on the interviews, four categories of analysis were established: motivations for entering the program, challenges in medical school, experiences of withdrawal, and persistence in undergraduate studies. Motivations for studying medicine at the institution varied and included personal development, commitment to the community, and the opportunity to enter the institution due to affirmative actions. Described challenges encompassed issues related to the course's methodology, weaknesses in basic education, separation from family, and economic challenges. Participants recounted moments when they considered dropping out but highlighted various strategies for persistence, such as institutional support through scholarships, pedagogical guidance, faculty supportive of the indigenous cause, fellow indigenous students, and the indigenous collective within the institution.

The literature in the field of child and adolescent mental health points to the school context as a potent space for the development of actions promoting the mental health of teenagers, but it also signals a shortage of national papers on this theme, especially concerning the involvement of teenagers in the process of producing knowledge about themselves. Thus, the present research aims to understand and analyze, in collaboration with adolescent students from a public school, elements related to the theme of mental health in adolescence using the “Cine Debate” strategy. A qualitative research was conducted using the creative strategy of “Cine Debate”. Teenagers from a public school in the second cycle of elementary education participated in the study, attending 2 sessions where films were screened, followed by discussions. The participating teenagers also responded to a questionnaire for process evaluation. The discussions and the evaluative process were subjected to Bardin's Thematic Analysis. Three themes emerged from the analysis of the results: "Perspectives on relationships: challenges, obstacles, and importance"; "Feeling in adolescence"; "Cine Debate: how to be a possible strategy." The study contributes to presenting the perspectives of teenagers on this stage of life, on social support, and on possible ways to conduct a debate activity based on the theme of mental health in the school context.

The pH meter is currently one of the most commonly used probing devices, employed daily in industry, scientific research, and medicine. The search for new sensor materials is of great technological interest. In this work, we produced an ionic-conducting glass from the system Li2O-Y2O3-SiO2 using the Aerodynamic Levitation technique and later developed an all-solid-state pH sensor. An arrhenian tension response to change in pH was found, with a 43mV/pH coefficient. To better understand this characteristic, we simulated the Li2O-SiO2 system using Molecular Dynamics, which has extensive literature both in molecular dynamics and experiments, and compared its dynamic and structural properties with those of the Li2O-Y2O3-SiO2 glass. The diffusion coefficient of the latter was found to be two times larger than that of the former. It was also observed that the structural properties are very similar, except for the coordination numbers of the Li-O and Si-Si pairs, possibly indicating a less polymerized structure and higher lithium ion mobility.

This dissertation comprises two interdependent chapters. In the first chapter, I carried out a systematic literature review, focusing on articles on forest restoration, ecological restoration, carbon and remote sensing up to November 2022. The systematic review was conducted using the Web of Science database. Exclusion and inclusion criteria were applied, resulting in 38 studies that were analyzed based on information such as place of publication, location of the study, type of vegetation, type of restoration, type of satellites and modeling used in the scientific articles. In the second chapter, an area undergoing restoration using the direct sowing method was monitored from 2018 to 2022, and each year the vegetation indices (NDVI, SAVI, EVI, PRI and CO2Flux) were analyzed to understand the behavior and growth of the restored vegetation in each year. At the same time, forest inventory data collected by the SemeAR/UFSCar Research Group was used. Using this data, it was possible to calculate the total biomass (t.dm/ha) and the carbon stock in the trees and in the stratum (tCO2e), establishing relationships with the vegetation indices by means of a multiple linear regression analysis using the Stepwise technique in RStudio. The main results of this work include: (i) mapping research into forest restoration, ecological restoration, carbon and remote sensing; (ii) calculating the carbon stock and biomass for the study area, restored using the direct seeding technique; and (iii) comparing the forest inventory data with the information generated by the vegetation indices, highlighting the relationship between these indices and the information on the carbon stock.

Doctors generally establish a vertical relationship with their patients, in which there are many asymmetries in the dialogue, but this socio-historical construction of asymmetries and distancing can be mitigated when the doctor brings his discourse closer to the patient, humanizing his professional practice. Medical schools can help with this through their role in training new professionals. With this in mind, this research focused on analyzing simulations of care provided virtually by medical students at a federal university in the interior of the state of São Paulo, in order to understand how students are evaluated and, based on this evaluation, how they construct their discursive styles. In order to do this, we started with French semiotics, especially the writings of Jacques Fontanille and his semiotic practices, and we used the concept of Zilberberg's tensiveness and Landowski's zoosociosemiotics. We elaborated and categorized 4 main discursive styles of doctors in training: humanized, bureaucratic, emotional and indifferent. In our analysis, we noticed a movement on the part of the university to get students to identify more with the humanized style and to understand it as conforming to the norm. We hope that this semiotic elaboration of discursive styles will enable new analyses of doctor-patient relationships, which are still lacking in studies and research in the field of linguistics.

Deforestation in the Legal Amazon region is one of the main factors generating greenhouse gas emissions. These emissions can be minimized with the efficient use of areas destined for agriculture in the region. Given this context, this study aims to measure the growth in Total Factor Productivity - TFP - based on data from the 2006 and 2017 Agricultural Censuses, Municipal Agricultural Production - PAM - and the state's Gross Domestic Product - GDP - for agriculture, all published by the Brazilian Institute of Geography and Statistics - IBGE, as well as data from the Greenhouse Gas Emissions and Removals Estimation System - SEEG. The estimates were made using the Malmquist (M) and generalized Malmquist (GM) indices, which do not take into account the generation of undesirable by-products, the Greenhouse Gases (GHGs). These indices were compared with the Malmquist-Luenberger (ML) and global Malmquist-Luenberger (GML) indices, which take into account the presence of these by-products in agricultural production. The results pointed to a growth in TFP for the Legal Amazon, both for productivity and for the change in technical efficiency and technological efficiency. However, for the GML and ML indices, which take into account the existence of by-products, growth was lower than for the M and GM indices. The results also show that in 56% of the municipalities in the Legal Amazon there is a greater productive emphasis on economic growth.

In modern times, electricity has become a vital necessity, but its use can trigger a series of problems related to improper waste disposal, often resulting in the release of harmful substances into the environment and human health. These substances include elements such as mercury and lead, which can cause neurological damage, kidney and respiratory problems. In addition, this type of improper disposal can cause serious environmental damage, polluting the soil, water, and air. In this context, the importance of implementing public policies and environmental awareness focused on proper disposal stands out. This study aimed to investigate the problems arising from improper disposal of such waste and to assess the level of understanding of the target audience regarding the concept of reverse logistics, through the application of a form. The analysis of the responses revealed a lack of overall understanding of the concept of reverse logistics and also regarding the proper disposal of fluorescent lamps by a large part of those surveyed. Thus, a proposed solution would be the implementation of environmental education programs, combined with investments in public policies, aiming to raise awareness among the population about the importance of environmentally sound disposal and to encourage them to adopt the practice of reverse logistics in a safe manner. Additionally, this study sought to elucidate the harms resulting from improper disposal and the benefits arising from reverse logistics regulated by Decree No. 10,936/2022. Keywords: Fluorescent lamps. Reverse logistics. National Solid Waste Plan.

In 2050 the world population will be more than 9 billion people and to meet this growing food demand it will be necessary to increase food production by at least 60%. To solve these problems, fertilizers are increasingly being used on plantations, often indiscriminately, resulting in various environmental impacts. As a possible solution to remedy or reduce environmental impacts arising from the incorrect use of fertilizers and waste of water, new technologies have emerged, among them, one of the most promising is the use of hydrogels in the soil, as some have great absorption and release properties. gradual release of water and potential to bind to various substances, enabling the controlled release of fertilizers. Therefore, this work aims at the synthesis and characterization of poly (vinyl alcohol) (PVA) hydrogels for application in rational use of water and release of NPK fertilizers in soil. The hydrogels were called HPVA and synthesized in different proportions considering the stoichiometry in moles of free OH present in PVA per mole of EDTAD, being 10:1, 20:1 and 100:1. They were characterized by Fourier transform infrared absorption spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetry (TG) and swelling capacity. The most stable HPVA was tested for absorption and release of NPK in soil and had its biodegradation and phytotoxicity characteristics evaluated, demonstrating the capacity for controlled release of water and NPK in soil in a bean seedling plantation and not proving to be phytotoxic, in addition to being biodegradable. Therefore, HPVA demonstrated to be a promising material for rational use of water and release of fertilizers into soil.

The study aims to understand issues related to linguistic accessibility in the Portuguese language discipline for deaf students in Technological High School, within the context of remote teaching. The research involved reflections in partnership between the researchers and the dyad of the teacher and Educational Interpreter (EI) for the deaf student. The choice of collaborative reflective spiral arises from the fact that it provides conditions for knowledge construction to occur in pathways, with the principle of decision-making collectively, taking into account all participants in the research. The explicit understanding and joint consideration of pedagogical actions led each participant to review their practices. The methodological data collection procedures are organized into four spaces. Spaces 1 and 2 refer to general classes and individual sessions, conducted on the Microsoft Teams platform, while Spaces 3 and 4 relate to meetings on Google Meet among the researchers, the Portuguese language teacher, and the EI to discuss collaborative proposals. The study highlights that this perspective has led to improvements in the teaching and learning of the deaf student, particularly as Sign Language gains more prominence in reflections on teaching Portuguese as a second language. For these and other reasons, we conducted this investigation and advocate for its existence, not only as a process of training and personal/professional development for the participants but also as a project for the production of scientific knowledge and ongoing training for educators involved in the process of linguistic accessibility for deaf individuals in high school.

The introduction of Pinus spp. in Brazil, it causes a series of environmental disorders and can lead to the impoverishment of biodiversity through its invasive potential. Thinking about the difficulty of obtaining quantification and geolocation data of individuals, this work aims to compare two deep learning models for automated segmentation of Pinus spp. crowns. The comparison was carried out between a model manually trained by the Mask R-CNN algorithm (supervised classification) and an existing model, SAM (unsupervised classification). Mask R-CNN presented 81% intersection over the union of polygons and 88% overlap rate between the manually delimited Masks and the masks segmented by the algorithm, while SAM presented results of 72% and 77%, respectively. The results found reinforce the importance of studies related to new remote sensing technologies for monitoring native vegetation as a biological conservation tool.

In recent years, the wine sector has presented considerable growth, resulting in increased production and, consequently, an increase in the effluents generated during winemaking. Polyphenols stand out among the components present in these effluents due to their analgesic, antimicrobial, and antioxidant properties. However, they can become contaminants in high concentrations. Given this scenario, it is necessary to develop effective methods for recovering these substances and water reuse, emphasizing the adsorption process that permits the reuse of the adsorbed compounds. This project uses rice husks, an agribusiness waste, to obtain zeolite-based magnetic nanocomposites for chlorogenic acid (CGA) adsorption. The synthetic faujasite (FAU) zeolite was initially synthesized and modified with silane agents to optimize the interactions with the polyphenols during the adsorption process with the zeolite nanocomposites obtained from the rice husks. The adsorption tests were carried out using FAU nanostructures silanized with (3-aminopropyl) triethoxysilane (APTES), trimethylchlorosilane (TMCS), and a combination of both under mechanical agitation for 24 h. FAU:APTES:TMCS stood out, showing better performance in the adsorption of ACG (20 mg L-1) compared to FAU without functionalization, achieving removal percentages of 12.78% and 67.80% for FAU and FAU:APTES:TMCS, respectively. The zeolite optimization, using high-purity silica extracted from rice husks, was carried out by investigating the hydrothermal synthesis time to obtain the FAU phase. The FAU phase most evident was in the 18-hour synthesis period (Z18), with a surface area of 217.69 m2 g-1 and a zeta potential of -38.87 mV, indicating stability in aqueous solution. The Z18 zeolite was modified (Z18 M) with the APTES:TMCS silane mixture and used to obtain the magnetic nanocomposites. For immobilizing the zeolites obtained from rice husks, copper ferrite heat-treated at 500ºC (F500) was used due to effective magnetic properties, a lower impurity index, smaller particle sizes, and good stability in aqueous solution. In this respect, the magnetic composites Z18:F500 and Z18 M:F500 showed effective magnetic properties and element distribution along the surface evaluated by energy dispersive X-ray spectroscopy (EDS), achieving GCA adsorption rates of 31.96% and 79.53%, respectively. In this way, it is concluded that silica obtained from rice husks proved an excellent candidate for the sustainable synthesis of zeolites. The zeolite surface modification led to greater efficiency in the recovery of ACG in aqueous media. Finally, the present work presents an alternative for reusing agribusiness waste and recovering polyphenols from wine effluents, contributing to a system capable of magnetic removal in a way that favors the circular economy.

In the genus Anastrepha (Diptera: Tephritidae) of fruit flies, the fraterculus group stands out for having highly generalist species specialized in different fruits, being one of the most economically important for national and global agriculture. In general, such species are differentiated through morphological characters, however the limits of this differentiation are difficult to determine for some taxa, especially in the fraterculus species group, which presents inclusive cryptic species. This happens in some cases due to the recent separation between species, but also due to overlapping of character measurements . This phenotypic variation may even occur through the action of epigenetic factors, since these changes may be related to environmental stimuli that trigger rapid responses. This work aimed to investigate the effect of hosts fruits on populations of Anastrepha fraterculus, identifying phenotypic variations in several morphological characters present in the head, thorax, aculeus and wing, as well as investigating the presence of epigenetic marks, such as DNA methylation, between specimens that emerged from different fruits. For this purpose, flies derived from the ecosystem were used, collected from five different hosts (cherry do rio grande, pitanga, uvaia, guava and guabiroba) around the Federal University of São Carlos – São Carlos campus. Morphometric analyzes were carried out on 117 samples from the 5 fruits found, with 18 morphological characters being analyzed using the multivariate statistical method, such as principal component analysis (PCA), discriminant analysis (DFA) and Mahalanobis distance (MD). Epigenetic analyzes were investigated in a subset of these flies, using data obtained through sequencing on a MinION equipment from Oxford Nanopore Technologies of two pools of heads per fruit, which allows the study of 5mC and 6mA DNA methylation. Methylation calling at 6mA sites between flies that emerged from different fruits was done using the mCaller software and its variation between samples (DMRs) investigated by a non-parametric analysis. In turn, an analysis of differentially methylated 5mC regions (DMRs) was performed using the pycoMeth pipeline, the results of which were investigated for enrichment of gene ontological categories (GO). The morphometric results indicated phenotypic variability in morphological characters of flies from five different fruits enough to separate the vast majority of samples emerging from different fruits. Epigenetic analyzes allowed recording for the first time the presence of DNA methylation in fruit flies A. fraterculus at both cytosines (5mC) and adenines (6mA). The investigation into the distribution of these DMRs suggested important genes in the process of differentiating this species into different fruits, as well as several enriched classes of genes responsible for different functions in biological processes, including the morphogenesis of anatomical structures and the development of the nervous system. These results provide a basis for future investigations into epigenetic modifications and phenotypic variability in fruit flies, highlighting their relevance in the regulation of phenotypes, host influence and choice, and evolutionary adaptation. Understanding these adaptation patterns is crucial not only for taxonomy, but also for elucidating the evolutionary processes, and ecological dynamics, involved in the interactions between flies and their hosts.
