Título: Assembleias de aves de sub-bosque em floresta ombrófila mista e plantações de coníferas nativas e exóticas Resumo em Língua Estrangeira: The decline of natural forests is a serious problem that can be alleviated by the growth of planted forests. Therefore, it is important to understand how these plantations can contribute to the maintenance of forest biodiversity. In this sense, our aim was to investigate whether conifer plantations, both native (Araucaria angustifolia) and exotic (Pinus elliottii), that are over 50 years old, have an understory presence, and are located close to natural forest fragments, can retain a diversity of birds similar to that found in natural forests (Mixed Ombrophilous Forest). To achieve our objective, we compared understory density, as well as understory bird richness, abundance, and composition among these three forest types. The study was conducted in the Passo Fundo National Forest, a sustainable use conservation unit located in Mato Castelhano, RS. Birds were sampled with mist nets in 18 plots, six in each forest type. To analyze the data, we used three rarefaction curves for richness, ANOVA with subsequent Tukey test for abundance and understory density, and Non-Metric Multidimensional Scaling Analysis (NMDS) for species composition. Therefore, our results showed that rarefied species richness did not differ among the three forest types, while abundance and species composition did, with abundance being higher in the natural forest, followed by the Araucaria and Pinus plantations. Additionally, the species composition of the natural forest was more similar to that of the Araucaria plantation than that of the Pinus plantation. Thus, our results indicate that planted forests, especially those with native trees, can contribute to the maintenance of forest bird communities. Tipo: Trabalho de Conclusão de Especialização

Título: Assembleias de aves noturnas em florestas naturais e plantadas na ecorregião da Floresta de Araucária Resumo em Língua Estrangeira: Nocturnal birds, although widely distributed, remain poorly understood and exhibit sensitivity to environmental changes, being influenced by factors such as habitat structure and circadian rhythms, which regulate their activity patterns, vocalizations, and reproduction. However, their study is challenging due to low detectability, with most records obtained through their vocal behavior. Passive acoustic monitoring (PAM) has proven to be an effective tool to overcome this limitation, enabling aural species identification. In this study, we used PAM to investigate the distribution and vocal activity patterns of nocturnal birds in the Floresta Nacional de Passo Fundo, Rio Grande do Sul, Brazil. In February 2024, autonomous audio recorders were deployed at 18 sampling units distributed across remnants of natural forest and plantations of Araucaria angustifolia and Pinus elliottii, resulting in approximately 3,000 hours of recordings. We identified seven species across three orders and four families, including a new record for the area (Glaucidium brasilianum). Strix hylophila, Lurocalis semitorquatus and Asio stygius were the most frequently detected species, each exhibiting distinct vocal activity patterns: S. hylophila vocalized throughout the night, L. semitorquatus was more active at dusk, and A. stygius concentrated its vocalizations between 20:00 and 00:00. The number of records of S. hylophila and L. semitorquatus did not differ significantly among the habitat types studied, while A. stygius was recorded only at a single sampling unit located in a plantation of Pinus elliottii. This study demonstrated the effectiveness of passive acoustic monitoring in detecting nocturnal bird species, identifying patterns of distribution and vocal activity, and thus filling gaps in knowledge about the local nocturnal avifauna.

Título: Aves de sub-bosque como bioindicadoras de florestas naturais e plantadas no extremo sul da Mata Atlântica Resumo em Língua Estrangeira: The presence or absence of species in an environment can indicate its environmental quality. Therefore, identifying indicator species is essential for assessing the conservation status of ecosystems. In this study, we aimed to identify indicator birds in natural and planted forests with Araucaria angustifolia or Pinus elliottii in the Passo Fundo National Forest, RS. To survey birds, we used mist nets in 18 sampling units, with six in each forest type. A total of 51 species were recorded, of which 23 were analyzed as they were captured 10 or more times. Of these 23 species, only four species were associated with specific forest types: Leptopogon amaurocephalus, Synallaxis cinerascens, Chiroxiphia caudata, and Zonotrichia capensis. The study indicated that the forest types are not sufficiently different for most species to prefer one forest type over the other. This result suggests that planted forests can serve as complementary or alternative habitats for most of the recorded species, including species considered dependent on forest habitat.

Título: Letramento Digital Crítico por meio do Trabalho Pedagógico no curso técnico em Sistemas de Energia Renovável Resumo em Língua Estrangeira: The enhancement of Critical Digital Literacy (CDL) through pedagogical work (PW) within the context of integrated education aims to foster the development of skills for understanding, using, and critically and responsibly evaluating the digital technologies available in cyberculture. This study aimed to analyze the conceptions of pedagogical work necessary for the development of CDL in the integrated education of the Technical Program in Renewable Energy Systems at the Federal Institute Farroupilha – Jaguari Campus. The research adopts a qualitative methodological approach, characterized as a descriptive study with an exploratory dimension for the development of a case study. The sample consists of 10 teachers from the Technical Program in Renewable Energy Systems (SER), integrated into Upper Secondary Education at the Federal Institute Farroupilha – Jaguari Campus. Data were produced through semi-structured interviews, recorded on video and later transcribed, in which teachers’ conceptions regarding the contributions of pedagogical work to the development of CDL, as it unfolded throughout the historical trajectory of the program, were analyzed. Data analysis was conducted using Discursive Textual Analysis (DTA). The study contributes to Research Line 2, Organization and Memories of Pedagogical Spaces in Professional and Technological Education (PTE), within Macroproject 6 – Organization of Pedagogical Spaces in PTE, through a case study of the SER Technical Program.The findings indicate that teachers hold a complex understanding of CDL, seeking to transcend the merely technical use of digital tools. Despite intentional pedagogical practices, the development of CDL is affected by challenges such as unequal access, insufficient technological infrastructure, and certain curricular limitations. Nevertheless, educators strive to address these challenges by integrating CDL into PW, generating a dialectical movement involving social, political, pedagogical, and technological dimensions, fostering critical analysis of reality and aiming at integrated education and student autonomy. The research concludes that the curricular transversality of CDL is a fundamental pillar for enabling the development of pedagogical work and the integral education of students, materializing through collaborative pedagogical practices that overcome knowledge fragmentation and pursue an omnilateral and polytechnical education. As a product of this research, an educational guide in e-book format was created to support the development of PW and promote CDL within integrated education. The e-book is organized into four chapters that sequentially address: the epistemological foundations of PTE, the historical conception of the Integrated SER Program, the conceptual bases for integrating CDL through PW, and, finally, an analysis of teachers' understanding of this integration. This study invites PTE educators to understand and reflect on their mediating role in integrating CDL with pedagogical work. It seeks to foster dialogue and inspire further investigations into this crucial yet still underexplored topic, which is essential for the development of PTE in light of the continuous global technological evolution.
