Título: Efeitos da relação filogenética e da similaridade funcional na invasibilidade de plantas na Caatinga Autor(es): Almeida, Thieres Santos Abstract: One of the main questions in biological invasions studies is the reason why numerous species are introduced, but only some become invasive. This shift in status has been justified by the phylogenetic relationship and functional similarity between exotic and native species. However, these patterns have not been explored in semi-arid environments like the Caatinga. Thus, the aim of this work is to test how phylogenetic and functional similarity between exotic and native plants in the Caatinga affect invasion status and distribution of invasive species. To achieve this, we constructed a list of exotic plants and obtained their respective invasion statuses in the Caatinga. We gathered occurrence data for these species and native plants. Additionally, a functional database was constructed for these species, including Leaf Area (LA), Height (H), and Seed Mass (SM) attributes. Using the occurrences, we created diversity fields for exotic species, representing the composition of native species that co-occur with each exotic species and calculated phylogenetic metrics for the focal species' distance to its field. Binomial GLMs were employed to assess whether changes in status from exotic to naturalized and from naturalized to invasive are influenced by phylogenetic relationships and functional attributes. For invasive species, we tested if observed phylogenetic distance values differ from those expected by chance. Lastly, we analyzed if there are functional similarities between the statuses of exotic species and native plants. We found that plants phylogenetically closer to Caatinga natives are more likely to become naturalized and invasive. Smaller plants also have a higher probability of becoming naturalized. Among invasive species with a phylogenetic relationship different from what is expected by chance, there is a prevalence of species phylogenetically closer to natives in their field. In comparing statuses, naturalized and invasive plants were found to be shorter and have smaller leaves and seeds than native plants in the Caatinga. The results indicate that Caatinga's environmental filter appears to favor species more similar to natives. The observed functional differences suggest that naturalized and invasive species are competitive, adopting strategies similar to native plants of Caatinga, such as seed bank formation and dense populations during a specific period of the year.

Título: Ensino de estatística descritiva com Python : uma proposta aplicada ao ensino médio Autor(es): Santana, José Eugênio Andrade Abstract: The teaching of Descriptive Statistics in High School faces challenges related to data interpretation, tables, graphs, and the understanding of measures of central tendency and dispersion, difficulties frequently observed in school practice. Considering the importance attributed by the Brazilian National Common Core Curriculum to the reading, interpretation, and critical analysis of statistical information, this study aimed to propose, apply, describe, analyze, and reflect on a sequence of activities for Descriptive Statistics mediated by the Python programming language, aiming to integrate calculations, graphical representations, and data interpretation. This study is an experience report with a qualitative approach, developed in High School Mathematics classes at Colégio Estadual de Tempo Integral Castro Alves, located in Adustina, Bahia, Brazil. The methodological proposal consisted of integrating conventional instruction of statistical content with computational practices in Python, in which students simulated data, organized information into tables, constructed graphs, and calculated statistical measures, relating these results to the analyzed data sets. The data were analyzed through triangulation involving teacher observations, students' productions, and a feedback questionnaire, aiming to understand the perceptions and reflections emerging from the developed experience. As an educational product, a sequence of activities mediated by Python was developed, aiming at the development of statistical interpretation. The results indicate that the proposed approach has the potential to foster the understanding of Descriptive Statistics concepts and expand the possibilities for data interpretation, in line with the demands of Mathematics Education. It is not intended to claim that the use of Python, by itself, guarantees better learning outcomes, but rather that its use as a mediating tool showed potential to foster statistical interpretation processes, expand possibilities for data analysis, and stimulate students' engagement in the proposed activities.

Título: Caminhos e movimentos: relações construídas no percurso de vidas das rezadeiras/rezador Autor(es): Santos, Edislaine Oliveira dos Abstract: Esta investigación busca comprender el protagonismo de las mujeres y los hombres curadores e yerberos que hacen las limpias y sanaciones en sus comunidades, investigando cómo sus prácticas articulan relaciones que abarcan la comunidad, la familia, el don y la naturaleza. Así, se observa a Dona Lauzina, Seu Zé y a Dona Zuzinha (in memorian), a través de sus trayectorias y la forma en que sus caminos y hogares se convierten en puntos de encuentro para las líneas de vida (LEWITZKI, 2019). El trabajo hace un diálogo con el concepto de personaje de Brandão (1982), que los destaca como agentes activos en la construcción y reproducción de su cultura, utilizo del concepto de líneas de Ingold (2015), que relaciona las prácticas cotidianas con personas, objetos, lugares y/o sus haceres. Desde la perspectiva de Lewitzki (2019), analizo las relaciones construidas por los movimientos y recorridos de los curadores. A continuación, la investigación va más allá de sus caminos iniciales y mira a los mercados de Corona y San Juan de Dios en Guadalajara-México, donde pudimos acompañar Leslie Belmonte, Javier Salazar y Luiz Alberto, todos curadores que unían el comercio de objetos para curaciones y una mezcla de prácticas esotéricas, de santería y cristianas, centralizando sus conocimientos en la curación. El objetivo de esta segunda parte es presentar las prácticas de estos curadores, centrándose en la descripción de sus lugares de trabajo y la forma en que llevan a cabo sus prácticas de curación. Ambas secciones se basan en el método de investigación cualitativo, utilizando investigación bibliográfica y un enfoque etnográfico, con observación participante en el campo y entrevistas en profundidad.

Título: Entre agulhas, punhais e câmeras: cangaceiras protagonistas no cinema (1976 – 2017) Autor(es): Souza, Maria Beatriz Rodrigues Abstract: The theme of cangaço found fertile ground in cinematic productions. The saga of Lampião and his mens entered the realm of the seventh art, resulting in roughly fifty films identified throughout the 20th century. However, only a few works have sought to portray the role of women cangaceiras. For this reason, this study examines how the audiovisual productions A Mulher no Cangaço (1976, by Hermano Penna), A Musa do Cangaço (1982, by José Umberto Dias), and Entre Irmãs (2017, by Breno Silveira) approached the protagonism of these female bandits. Two documentaries and one feature film were selected, respectively.The study investigates how these productions mobilized the memories and testimonies of women who took part in the cangaço. In dialogue with the history of the backlands (sertões), gender studies, and social discourse analysis, cinema emerges as a privileged space for the surfacing of marginalized memories, enabling these figures to be repositioned as protagonists of their own narratives. By revisiting the history of cangaço from a female perspective, elements once considered secondary could be inscribed as fundamental parts of this experience. This approach was made possible through the theoretical framework employed, which shed light on the subject. Accordingly, the analysis intersects gender as a category of analysis (Scott, 1995), the history of women (Perrot, 2007), subterranean memories (Pollak, 1989), and the testimonial turn in historical knowledge (Seligmann-Silva, 2022). Based on these reflections, it also became essential to consider the sertão and the discourses surrounding Brazil’s Northeast region (Albuquerque Jr., 1999, 2008, 2013; Araújo Sá, 2011, 2020, 2023). Methodologically, the study primarily focused on examining testimonies, dialogues, and scenes through the principles and procedures of social discourse analysis (Orlandi, 2002, 2007), alongside contributions from historiography on banditry. In the audiovisual productions, the main objective was to identify the agency and protagonism of women cangaceiras. The investigation further demonstrates how the testimonies of surviving participants, recorded in the documentaries, resonated in contemporary fiction, highlighting tensions between oppression and freedom, violence and resistance.
