SUMMARY:

The present doctoral thesis provides a comprehensive overview of the ecological importance of non-phyllothalamic bromeliads in the neotropical region, with a special focus on Encholirium spectabile in the semi-arid region of Brazil. The thesis is structured through various studies that come together in five chapters, addressing the relevance of these bromeliads to the local fauna and the implications of these interactions for the involved groups, as well as the conservation of these ecosystems. Research conducted from 2011 to 2018 reveals associations with a wide variety of fauna, including arthropods, amphibians, reptiles, birds, and mammals from various groups. E. spectabile performs various ecological functions, such as providing habitat, foraging, and food resources. Chapter 1: Bromeliads are highlighted for their role as ecosystem engineers, functioning as nursery plants and keystone species, forming diverse microecosystems. Despite their crucial role, these plants face a severe threat due to mining activities, emphasizing the need for conservation policies. Chapter 2: Birds, especially in the semi-arid region, use bromeliads for feeding, nesting, and resting, highlighting the interconnection between plant conservation and the preservation of bird species. Chapter 3: Explores the impact of Encholirium spectabile on arthropod diversity, emphasizing its importance in supporting diverse taxa, especially during the rainy season. The research underscores the ecological relevance of non-phyllothalamic bromeliads in challenging environments. Chapter 4: Discusses hymenopterans, clarifying the essential ecosystem services provided by these insects, emphasizing the need for conservation efforts to protect their interactions with bromeliads. Finally, Chapter 5: Highlights local knowledge about bromeliads, specifically macambiras, among the "sertanejo" people, revealing its multifaceted importance in providing ecosystem services, cultural identity, and support for biodiversity. Despite its crucial role, this knowledge is primarily held by the elderly, underscoring the need for broader dissemination and conservation efforts. Overall, these studies emphasize the importance of intricate ecological relationships, ecosystem services, and the cultural significance of bromeliads and their interactions, especially Encholirium spectabile, in the semi-arid region of Brazil, highlighting the urgency of conservation measures.
