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.

The absence of routine laboratory differentiation between Mycobacterium bovis and Mycobacterium tuberculosis in the Brazilian health system contributes to underreporting and hampers understanding of the disease's epidemiological dynamics. This study analyzed the occurrence and spatial distribution of bovine tuberculosis cases reported to the Paraná Agricultural Defense Agency (ADAPAR) and their correlation with human tuberculosis incidence recorded in SINAN/DATASUS across the 24 municipalities of the Cascavel Metropolitan Region (CMR) from 2015 to 2024. This is a descriptive-analytical quantitative study based on publicly available secondary data. Incidence coefficients per 100,000 inhabitants and per 100,000 animals were calculated, and Pearson correlation was applied between the two time series. During the evaluated period, 1,199 bovine and 1,075 human cases were recorded in the region. Correlation analysis revealed a moderate to strong negative dynamic in the CMR as a whole (r = -0.60) and in Cascavel (r = -0.73), suggesting predominance of inter-human transmission, while in the remaining municipalities the correlation was negligible (r = -0.08). The results highlight gaps in surveillance integration and reinforce the need for public policies grounded in the One Health approach, including differential molecular diagnostics and surveillance of the wildlife and livestock interface around Iguaçu National Park.

Among these waste materials, Medium Density Fiberboard (MDF) panels stand out. Widely used in furniture manufacturing, they require specific care regarding their disposal and energy recovery due to synthetic formaldehyde-based resins in their composition. In this context, this dissertation aimed to develop a technical-conceptual proposal for the energy recovery of MDF waste generated in the furniture hub of Toledo, Paraná, Brazil, through briquette production, considering torrefaction as a pre-treatment step capable of contributing to the reduction of undesirable compounds and improving the material's characteristics as a solid fuel. The research is qualitative and exploratory, developed based on a literature review, a survey of information on waste generation and disposal in the Toledo furniture hub, and a comparative analysis of the thermochemical characteristics of raw and torrefied MDF. The results indicated an estimated generation of approximately 35 tons of MDF waste per month in the studied furniture hub, consisting mainly of offcuts, trimmings, and sanding dust. The diagnosis also highlighted limitations related to the disposal of this waste, including the lack of structured reverse logistics, fragmented management initiatives, and inappropriate disposal and burning practices. The literature review showed that MDF has significant energy potential, with a higher heating value of approximately 4,427.8 kcal kg⁻¹ and a low ash content. For the material subjected to torrefaction between 260 °C and 280 °C for 60 minutes, major improvements in energy properties were identified, such as a reduction of up to 65% in residual formaldehyde, an increase of up to 20% in heating value, reduced moisture content, higher hydrophobicity, and improved grindability. These results reinforce the role of torrefaction as a pre-treatment alternative to make the waste more suitable for densification and energy recovery, provided that appropriate emission control measures are adopted.

In this context, the search for sustainable solutions for solid waste management becomes urgent. This study investigated the feasibility of using human hair mass (HHM), generally discarded as waste, as an agricultural input. Composed of approximately 16% nitrogen (N), as well as carbon (C) and sulfur (S), HHM has agronomic potential. The use of HHM residue (HHM) as a fertilizer in three crop cycles and as a substrate component in one crop cycle was evaluated for radish (Raphanus sativus L.) varieties (Redondo Pequeno and Gigante Crimson). The HHM was characterized chemically and physically, including scanning electron microscopy (SEM) analysis. N contents ranged from 10.83% (smoothed) to 15.46% (dyed). A minimum N content of 10% was adopted. Agronomic trials demonstrated that RMCH favors plant root and leaf development, outperforming the control and comparable to urea. Soil analyses revealed that RMCH increased the levels of phosphorus, sulfur, boron, organic carbon, and organic matter, while urea caused losses of C and S. As a substrate, RMCH demonstrated good moisture retention and stimulated initial seedling growth. It is concluded that RMCH has potential as a fertilizer and substrate component, promoting the circular economy by transforming human waste into an agricultural resource.
