SUMMARY:

Conserving bee diversity and ensuring pollination service in food production systems is an economically relevant alternative to subsidizing sustainable agroecosystems globally, especially in tropical regions. In this context, the fragmentation of natural habitats in the landscape and the current management practices of production areas are factors that must be considered to minimize the impacts of agricultural expansion on bee diversity. Such factors are also determinants for the structuring, stability, and resilience of plant-bee interactions in agroecosystems and the maintenance of gene flow and genetic diversity among populations of wild pollinating bees. Therefore, this thesis aims to evaluate how environmental resources at different spatial scales contribute to the maintenance and management of bees in organic agricultural systems and their consequences for the provision of pollination services in agroecosystems in the Cerrado biome. It is important to think about strategies that promote the provision of pollination services in agricultural systems that do not compromise the natural habitats of Cerrado, the most diverse savanna in the world, considered a biodiversity hotspot. We also hope to propose a sustainable management strategy based on natural pollination and the introduction of native stingless bee nests for pollination in organic tomato crops. That is because we aim to increase the technologies available to farmers, especially for those seeking more sustainable farming systems. The thesis is structured into three chapters, where bee species and their interactions will be evaluated in organic tomato crops in the Federal District. For this, we work with an approach involving three fundamental scales for understanding ecological processes that act on biological communities but are still little considered together in ecological studies, especially in agroecosystems: the landscape scale, the farm scale, and the local scale
