Gymnogeophagus taroba is an endemic, small species and studies on its bioecology are scarce. Thus, the aim of the study was to characterize the population structure and feeding habits of G. taroba. Collections were carried out monthly from January 2010 to January 2011 and from September 2012 to December 2016, in the Lower Iguaçu River region, covering areas within the Iguaçu National Park (INP) and anthropized areas outside the INP. In all, 802 specimens were analyzed, with total length and weight ranging from 1.5 to 15 cm and from 0.02 to 51.90 g, respectively. The sex ratio did not show significant differences for the population and the largest length classes contained only male individuals. The weight-length relationship for both sexes exhibited isometric growth. The reproductive period established through the average variation of the Gonadal-Somatic Index (GSI) and frequency distribution of males and females encompassed between August and February, with reproductive peaks in September and November for females and in October for males. The size of the first gonadal maturation (L50) corresponded to 6.03 cm for males and 4.15 cm for females. The analysis of the frequency of degrees of repletion by periods (morning, afternoon and night), reveled greater feeding activity during the night. The feeding habit of the species, determined through the Index of Feeding Importance (IFI), was characterized as a benthic insectivore, with emphasis on the consumption of larvae of Chironomidae and Trichoptera. The study provides unprecedented information about certain parameters of the population structure, reproduction and feeding habits of G. taroba, which will assist in effective conservation actions for the species.

Brazil has established itself as the world's largest sugarcane producer, with the 2025/26 harvest reaching 673,283.8 thousand tons. This research aims to analyze how the Sectoral Chamber of the Sugar and Alcohol Production Chain (CSCPA) contributes to the formulation of public policies that promote the sustainability and competitiveness of this activity in Brazil, using a New Institutional Economics (NIE) approach. The study investigates how the agents within this production chain articulate strategies and influence political decision-making to strengthen the sector. Methodologically, the research is characterized as qualitative and employs multiple approaches: a systematic literature review of articles presenting empirical evidence on topics relevant to the CSCPA; Content Analysis (CA) of the minutes of its meetings, used to categorize and interpret data and documents; and Discourse Analysis (DA) of interviews conducted with sector representatives participating in the CSCPA, enabling an understanding of how discourses are constructed and disseminated within society in their historical, social, and ideological contexts, as well as allowing the exploration of both explicit and implicit meanings present in the interviewees' statements. The results suggest that the representatives of the links composing the CSCPA construct, through their discourses, a narrative that legitimizes specific priorities, such as sustainability, technological innovation, and bioenergy, while simultaneously framing the challenges faced by this production chain and guiding possible solutions. Thus, strategies function as discursive practices that articulate technical knowledge and political action, transforming sectoral demands into institutionally viable proposals. This dual institutional and discursive dimension reveals that the CSCPA's contribution to public policy formulation goes beyond a merely consultative role, establishing it as an active space for the co-production of public policy.

Although the municipality of Corumbá contains more than 44% of the Pantanal biome area, concentrated along the Paraguay River, and presents exceptional tourism attractions—especially related to sport fishing—there is still a lack of systematic studies that integrate the economic, institutional, sociocultural, and systemic dimensions of tourism in this territorial context. The theoretical framework articulates Douglass North’s Economic Base and Institutional Theory, Pierre Bourdieu’s social praxeology (habitus, field, and capital), and Mário Carlos Beni’s Tourism System Model (SISTUR). Methodologically, the research adopts a mixed-methods case study approach, using the Location Quotient (LQ) to measure economic specialization and Content Analysis to interpret documentary sources and participant observation data.The results indicate that Corumbá is a tourism-specialized territory, with Location Quotient values above 1 in all analyzed periods: 3.04 (2010), 3.74 (2020), and 2.15 (2024). However, the decline observed in 2024 reflects a loss of economic dynamism associated with institutional fragilities, administrative discontinuities, and path dependence centered on sport fishing. From a symbolic perspective, a dominant traditional habitus was identified, in which tourism is perceived as a natural vocation but lacks professionalization and innovation, resulting in a tourism field that is externally regulated and strongly dependent on the State. The systemic analysis based on the SISTUR model confirms that the tourism system is stronger in its isolated components than as an integrated whole, presenting exceptional environmental assets but significant gaps in governance (superstructure) and support infrastructure.The thesis concludes that tourism in Corumbá does not fully generate employment and income because its institutional and social bases have not been converted into an integrated and diversified economic structure. As an academic contribution to territorial development, a public policy proposal grounded in education is presented, aimed at strengthening Corumbá’s territorial tourism identity. This proposal seeks to overcome field fragmentation and reinforce governance mechanisms in order to activate local resources in a sustainable manner.

In the Curitiba Metropolitan Region (CMR), these deaths predominantly affect individuals of working age, especially young and adult men, producing impacts on life expectancy, population age structure, and the labor market. In this context, this study aimed to analyze the relationship between mortality from external causes and the main socioeconomic factors in the CMR in 2000, 2010, and 2022. Specifically, the study sought to characterize the region's sociodemographic profile; analyze the structure of overall mortality and mortality from external causes; estimate gains in life expectancy resulting from a 15% reduction in male deaths and a 5% reduction in female deaths from external causes; identify spatial patterns of mortality; and examine the association between socioeconomic factors and mortality from external causes. Secondary data were obtained from the Brazilian Institute of Geography and Statistics (IBGE/SIDRA), the Mortality Information System (SIM/DATASUS), and the National Registry of Health Establishments (CNES/DATASUS). Demographic and statistical techniques were applied, including Crude Mortality Rates, Age-Specific Mortality Rates, Life Tables, Multiple-Decrement Life Tables, Cause-Deleted Life Tables, spatial autocorrelation analysis using the Global and Local Moran's Index (LISA), and quasi-Poisson regression models due to overdispersion in the count data. The analyses considered demographic, socioeconomic, and health service variables. The results showed that the CMR has undergone demographic and epidemiological transition, characterized by declining fertility, population aging, and increasing life expectancy. However, external causes remain a major component of premature mortality, with pronounced excess male mortality concentrated among men aged 15 to 59 years, mainly due to assaults and transport accidents, whereas among women deaths were concentrated at older ages and were primarily associated with falls and other accidental injuries. Spatial analysis identified significant positive spatial autocorrelation only in 2010, revealing significant territorial clusters of mortality from external causes, predominantly associated with the male population. Quasi-Poisson regression models demonstrated significant associations between mortality from external causes and male sex, individuals aged 20 to 59 years, and municipal socioeconomic indicators, while higher income, gross domestic product per capita, and hospital bed availability were associated with lower mortality. Simulations of partial reductions in deaths from external causes indicated substantial gains in life expectancy, particularly among men. It is concluded that mortality from external causes in the CMR does not occur randomly but reflects structural, social, economic, and territorial inequalities, highlighting the need for intersectoral public policies aimed at preventing violence, accidents, and social vulnerabilities. This thesis contributes by integrating demographic, statistical, spatial, and econometric methods to better understand the determinants of mortality from external causes and their impacts on life expectancy and regional development.
