Title: Aranhas urbanas como potenciais predadoras de Aedes aegypti (Diptera: Culicidae) em ambiente urbano de Uberlândia, MG Abstract: Aedes aegypti is a vector of multiple pathogens, and massive efforts have been invested to understand its biology and develop control mechanisms. However, understanding how natural enemies of adult mosquitoes may affect their populations is still in its early stages. Spiders, particularly from the Salticidae family, have been suggested to possess the necessary characteristics to exert significant predation pressure on these mosquitoes in urban environments, unlike most other predators. Therefore, this study was dedicated to testing the hypothesis that an increase in spider density, especially Salticidae, is related to a decrease in the Ae. aegypti population. Indeed, we found that the incidence of dengue is negatively related to the general abundance of spiders in the city of Uberlândia, although it was not associated with the abundance of specific spider families, such as Salticidae. Further studies are needed to identify the extent of the direct interaction between spiders and mosquitoes in urban areas and to clarify whether both are affected oppositely by environmental conditions. Despite this, this is the first study to identify an opposing relationship between the spider community and mosquitoes in urban environments. These results thus provide the necessary foundation for the next steps in research in this field. Here, we discuss in more detail which methods will be of special value for understanding these interactions and population control for future studies.

Title: Entre retornos e permanência: Em busca dos sentidos da escolarização nas narrativas de estudantes da EJA noturna Abstract: This undergraduate thesis investigates the meanings attributed to schooling by students of Youth and Adult Education (EJA) in the night shift, through the analysis of their life narratives. The research is based on a qualitative and narrative approach, understanding that the construction and narration of stories is a way for subjects to organize and produce meanings about their experiences, articulating time, memory, and sense. The study used an online form and narrative interviews with night-shift EJA students, whose accounts were analyzed based on emerging categories. The results show that the narratives reveal trajectories marked by ruptures, returns, and challenges, but also by expectations of personal, professional, and social transformation. Participants attribute to EJA meanings associated with self-esteem, opportunity, welcoming, and resilience, highlighting the importance of night school for educational continuity amidst work routines. Therefore, we consider that listening to these narratives broadens the understanding of permanence and the meaning of education for young and adult workers, reinforcing the need for pedagogical practices sensitive to their realities and identities.

Title: Trophic ecology of Tropidurus torquatus on open and closed phytophysiognomies of the Brazilian Cerrado Abstract: Estudos de ecologia trófica são essenciais para definir nichos ecológicos, assim como as preferências alimentares nos ajudam a entender não apenas o que os animais comem, mas o que eles estão escolhendo comer. Este estudo investigou a dieta do lagarto Tropidurus torquatus em duas fitofisionomias diferentes, Cerrado sensu stricto e Floresta Semidecídua. Espécimes tiveram seus conteúdos estomacais analisados e a fitofisionomia não alterou significativamente as escolhas alimentares entre as populações, que foram estritamente compostas por artrópodes. Hymenoptera, especialmente formigas, foram as presas mais abundantes devido à estratégia de forrageamento senta-e-espera do lagarto, enquanto presas maiores e mais pesadas, como Pentatomidae e Bothriuridae, explicaram melhor as sutis variações entre os habitats. No geral, nossos resultados sugerem que T. torquatus demonstrou alta plasticidade alimentar e um comportamento alimentar generalista e oportunista. O padrão entre preferência e importância das presas mostra uma estratégia para otimizar a sobrevivência por meio das escolhas alimentares.
