Item type: Item , Diversidade de ácaros e a sua aplicação como bioindicadores de (in)sustentabilidade ambiental em sistemas agropecuários(Universidade Federal de Goiás, 2026-03-31) Falchi, Vanessa Leonel; Corte, Renato Bolson Dala; http://lattes.cnpq.br/2628859770848794; Daud, Rodrigo Damasco; http://lattes.cnpq.br/0051569214196052; Daud, Rodrigo Damasco; Lion, Marília Bruzzi; Tassi, Aline Daniele; Castro, Elizeu Barbosa de; Brasil, Leandro SchlemmerAgriculture and livestock production are among the human activities that generate the greatest environmental impacts. However, these activities encompass a wide range of management practices, resulting in varying levels of impact. Agricultural systems range from those based on the use of inorganic fertilizers and pesticides, which cause greater environmental damage, to more sustainable management approaches aimed at reducing environmental, social, and economic impacts. Therefore, it is essential to develop tools to assess the level of impact and, consequently, environmental sustainability according to the type of management adopted in agricultural systems. Bioindicators have great potential as tools for evaluating the impact of agricultural systems on the environment, however, studies addressing this topic are still incipient. In this context, this study aimed to investigate the application of bioindicators to predict the level of sustainability in agricultural systems. Initially, we assessed plant-associated mite diversity in citrus and pasture systems. Subsequently, we analyzed the use of these organisms as bioindicators of management quality in livestock pastures. In addition, we evaluated the potential use of plant-associated mites as bioindicators of agricultural (un)sustainability, using citrus production as a model system. Overall, this study contributes to the assessment of environmental sustainability in agricultural areas, as well as to the evaluation of management practices applied in agriculture and livestock systems.Item type: Item , Bioindicação, estrutura da paisagem e modelos de distribuição: uma abordagem multiescalar para abelhas Euglossini.(Universidade Federal de Goiás, 2026-12-17) Cristino, Gabriela Souza; Marco Junior, Paulo de; http://lattes.cnpq.br/2767494720646648; Silva, Daniel de Paiva; http://lattes.cnpq.br/1409353191899248; Nogueira, Denis Silva; Araújo, Thayane Nogueira; Contrera, Felipe Andrés León; Martins, Aline Cristina; Silva, Daniel de PaivaTropical ecosystems harbor high levels of biodiversity but are under strong anthropogenic pressure, such as habitat fragmentation, agricultural expansion, and climate change, which affect ecological processes and the maintenance of biological communities. In this context, bees play an essential role in pollination and ecosystem dynamics, with Euglossine bees being particularly important due to their strong association with forest environments and their frequent use as environmental bioindicators. Their sensitivity to environmental changes, combined with ease of sampling and wide distribution, reinforces their importance for biodiversity monitoring. The thesis is structured around three complementary axes. The first consists of a systematic review, based on the PRISMA protocol, synthesizing more than five decades of studies on Euglossine bees as bioindicators, identifying patterns and knowledge gaps, including taxonomic, spatial, and ecological deficits. The second axis investigates the effects of landscape transformation in the Cerrado, especially agricultural expansion, on the richness and abundance of these bees, considering the Habitat Amount Hypothesis and landscape metrics across multiple spatial scales. The third axis uses species distribution models to estimate suitable areas and sampling gaps for rare species, supporting conservation planning and guiding future inventories.Thus, the thesis integrates theoretical, empirical, and predictive approaches to understand how environmental changes affect Euglossine bee communities and to support conservation strategies in rapidly changing tropical landscapes.Item type: Item , Hipótese cladística, diversidade e classificação Oedionychina (Coleoptera, Chrysomelidae, Galerucinae, Alticini) no cerrado goiano(Universidade Federal de Goiás, 2026-02-25) Begha, Bruno Piotrovski; Prado, Laura Rocha; http://lattes.cnpq.br/8619995959929428; Oliveira, Sarah Siqueira de; http://lattes.cnpq.br/7040117047525988; Oliveira, Sarah Siqueira de; Konstantinov, Alexander; Viana, Jessica Herzog; Silva, Aline Amanda Sampaio da; Santos, Aluska Tavares dosEmbargoItem type: Item , Caminhos para uma agricultura e pecuária sustentáveis: intenções, práticas agroecológicas e desafios climáticos(Universidade Federal de Goiás, 2025-06-27) Werneck, Rhayane Pires; Marco Junior, Paulo De; http://lattes.cnpq.br/2767494720646648; Daud, Rodrigo Damasco; Togni, Pedro Henrique Brum; Lima, Edgar Luiz De; Andrade, Andre Felipe Alves De; Marco Junior, Paulo DeAgricultural intensification and the growing demand for food have led to significant environmental challenges, including biodiversity loss, pest proliferation, and climate-driven pressures on production systems. This thesis explores different but interconnected pathways toward more sustainable agriculture and livestock systems by integrating behavioral, ecological, and climatic perspectives. In the first chapter, we investigate the psychological and social factors influencing dairy farmers’ intentions to adopt Best Management Practices (BMPs) in Goiás, Brazil, using the Theory of Planned Behavior. The findings highlight the importance of attitudes and perceived behavioral control, while revealing unexpected resistance linked to social norms. The second chapter presents a systematic review on the use of companion plants for pest suppression in agricultural systems, synthesizing empirical evidence and identifying knowledge gaps regarding traditional practices in Brazil. The results confirm the effectiveness of plant-based strategies, especially intercropping and trap cropping, and advocate for the integration of local ecological knowledge into scientific research. The third chapter models future distributions of three major crop pests (Spodoptera frugiperda, Helicoverpa armigera, and Diatraea saccharalis) under climate change scenarios (SSP2-4.5 and SSP5-8.5), revealing species-specific responses and potential shifts in pest pressure across the Americas. Collectively, the chapters highlight the need for context-aware strategies that combine technical innovation, farmer engagement, and anticipatory planning to ensure sustainable agricultural transitions in a changing world.Item type: Item , Morfologia prediz ecologia?

This science is multidisciplinary as it relates to other areas of natural science and thus expands possibilities for new discoveries. Investigations that show the advances and possible gaps that may exist in the knowledge of vocalizations are still rare, especially in the tropics. In this research, we reviewed what was published in studies on vocalizations of South American birds and mammals available in the Scopus database between 1962 and 2020. We investigated the impact of the research on the number of articles published, in journals, more focused taxonomic groups, paper authors' affiliations and differences between countries scientific productivity. Studies on bird vocalizations over time have raised. There were taxonomic and geographic biases. Some groups and species are disproportionately more studied than others, such as Passeriformes, Cetartiodactyla and Chiropter. Strong economies had a higher density of publications. Areas such as Animal Behaviour and Bioacoustics were most studied in birds and mammals. We propose that, in the future, research efforts be redirected towards greater attention on species whose acoustic communication has little or no study and, mainly, those ones most endangered species. With these two reviews we hope to be able to contribute to reveal the panorama of what has been studied about vocalizations of South American birds and mammals and, in this way, serve as a guide to help and direct future research.
