This dissertation investigates the effects of ableism and psychological distress on the constitution of teachers’ professional identity, focusing on the perspective of critical autoethnography. The main objective is to understand how personal narratives, shaped by ableist interpellations and experiences of exclusion, can be re-signified as methodological and political tools in the production of knowledge within Applied Linguistics. Specifically, it aims to problematize the role of universities and schools in reproducing stigma, highlight the tensions between medical diagnosis and institutional recognition, and propose self-writing as a gesture of resistance. The theoretical framework is grounded in authors such as Foucault, Butler, Hall, hooks, Moita Lopes, and Garland-Thomson, who discuss identity, power, performativity, and disability. The methodological approach is anchored in autoethnography, emphasizing embodied and situated narratives that consider the researcher’s experience as legitimate data and as a criterion for analysis. The findings indicate that professional identity, far from being a stable essence, is traversed by ableist discourses that tend to reduce neurodivergent teachers to diagnostic labels. At the same time, autoethnographic writing makes it possible to reinscribe the diagnosis as a critical category and to construct more humane and engaged pedagogical practices. It is concluded that autoethnography, by articulating personal experience with critical theoretical perspectives, constitutes a counter-archive that inscribes historically silenced voices into the academic field.

Chickpeas are the second most consumed legume in the world and are important for feeding underserved populations due to their protein content. In Brazil, their production is incipient, requiring the import of a large portion of the grain consumed. Sitophilus oryzae (Coleoptera: Curculionidae) is a worldwide pest of stored cereal grains, but it has the potential to cause damage and losses to stored chickpeas. The objective of this study was to evaluate the resistance of chickpea genotypes to Sitophilus oryzae (Coleoptera: Curculionidae. The experiments were conducted in the laboratory and used the following genotypes: Desi 1605, Desi 10209, Desi 10108, Desi 1606, Desi 10159, BRS Toro, BRS Aleppo, BRS Kalifa, BRS Cícero, and BRS Cristalino, from the Vegetable and Legume Breeding Program of Embrapa Hortaliças. The resistance of the chickpea genotypes was evaluated at 30, 60, 90, and 120 days after pest infestation, determining the following parameters: number of live and dead insects, consumption, and percentage of grains damaged by the pest in each genotype. The genotype Desi 10209 showed resistance to Sitophillus oryzae . Sitophillus oryzae has the potential to cause significant damage to stored chickpea grains. The chickpea cultivar BRS Cícero showed susceptibility and the other cultivars moderate resistance to Sitophilus oryzae.

Riparian forests are ecosystems that are crucial for the protection of water resources and the maintenance of biodiversity, although they are often degraded by unplanned urban growth. Given this, the objective of the study was to evaluate the floristic composition and horizontal structure of tree communities subjected to varying degrees of anthropogenic influence in small (S - Ipameri) and medium-sized (M - Caldas Novas) cities, comparing them with protected areas (P) located in rural areas. Data collection was conducted in 59 plots of 400 m² (20x20 m) distributed across urban streams and legal reserves. Phytosociological parameters such as density, basal area, aboveground biomass, and carbon stock were estimated. Diversity was measured using the Shannon and Simpson indices, and richness using the Chao 1 estimator. To compare the areas (P, M, and S), the Kruskal-Wallis test with Dunn’s post-hoc test was used. Floristic and structural similarity was assessed using the Jaccard and Morisita-Horn indices, supplemented by multivariate analyses, PERMANOVA, PCoA, and Indicator Species Analysis (IndVal). A total of 199 species were sampled. Protected forests (P) exhibited significantly higher values for all structural parameters: average species richness of 19 species per plot, density of 1,138.3 individuals/ha, and carbon stock of 36.8 t/ha. In contrast, the urban areas M and S showed reduced richness values and were similar to each other, with carbon stocks of 15.5 t/ha and 17.1 t/ha, respectively. The floristic composition revealed that the ETEPs maintain native species typical of riparian forests, such as Tapirira guianensis and Licania apetala, whereas urban areas are dominated by exotic species, including Leucaena leucocephala and Mangifera indica. Multivariate floristic and structural analyses showed greater similarity among forests in the urban zone, and PERMANOVA indicated no significant differences among these plots. Only four species (three of them exotic) were identified as indicators of riparian forests in the urban zone. The results demonstrate that urbanization promotes biotic homogenization, and the studied urban fragments can be characterized as novel ecosystems, marked by new species combinations and structurally simpler communities with lower levels of species richness and biomass.

Potassium is an essential nutrient for soybean crops, directly influencing plant growth, development, and productivity. The objective of this study was to evaluate the residual effect of potassium sources and rates on nutritional traits, morphological characteristics, and yield components of soybean. The experiment was conducted under field conditions during the 2024/2025 growing season in Ipameri, Goiás, Brazil, using a randomized block design in a 3 × 5 factorial scheme, with three potassium sources (potassium chloride, phonolite, and hydrothermally treated phonolite) and five rates (0, 50, 100, 150, and 200 kg ha⁻¹), with four replications. Leaf nutrient contents, relative chlorophyll index, morphological traits, and yield components were evaluated. Potassium sources did not influence most variables, except for leaf potassium content. Residual potassium rates affected leaf nitrogen, potassium, and silicon contents, as well as the chlorophyll index. Morphological characteristics were not affected, except for the insertion of the first pod. The 100-grain weight responded to potassium rates, while yield did not differ among treatments. It is concluded that alternative potassium sources show a residual effect similar to potassium chloride, maintaining satisfactory yield levels in soybean crops.

Fusarium is a widely distributed fungus, highly resilient and adaptable, responsible for severe diseases in various agricultural crops. Its ability to survive and adapt to climate change reinforces its global economic and phytopathological relevance. In this study, the aim was to estimate the population density of Fusarium sp. under different physical conditions, evaluate the effect of Trichoderma harzianum application, and characterize conidial germination. Soil samples were collected in gerboxes at the State University of Goiás, South Campus, Ipameri Unit. The gerboxes were divided into two treatments: control, intended for quantification of the natural population density of Fusarium sp., and biological treatment, which previously received a suspension of T. harzianum. The treatments were subjected to temperatures of 16, 20, 24, 28, and 32°C for ten days of incubation in BOD chambers under a 12 h photoperiod. After the incubation period, 1 g of soil was removed from the gerbox and suspended at a 1:100 dilution. Aliquots of 1 mL of this suspension were transferred to Komada medium for seven days at 24°C under a 12 h photoperiod. Subsequently, the number of colonies formed was counted, and the estimate expressed per gram of soil. In parallel, isolate Q-01-08 was obtained and subjected to pathogenicity tests on bean seeds, as well as evaluation of initial germination time, germ tube growth, and microconidia germination percentage. The experiment was conducted in a completely randomized design. The highest Fusarium density occurred around 24–25°C, reduced by approximately 55% at extreme temperatures and by 30–60% due to the action of T.harzianum. Isolate Q-01-08 showed high pathogenicity in bean seeds. Molecular identification based on ITS sequencing revealed 567/569 bp similarity with F. solani sequences. Temperature and light regime influenced germination, with delays at lower ranges, limitation between 24–27°C under light, and promotion of growth at 28–32°C in darkness, which also increased germination percentage above 24°C. It is concluded that the isolate has economic importance due to its pathogenicity and that its growth and behavior are strongly modulated by light and temperature conditions.
