Caracterização das comunidades de aves em áreas do bioma Mata Atlântica sob diferentes estágios de conservação

Abstract

The Atlantic Forest, recognized as a crucial global hotspot for biodiversity conservation, stands out for its species richness and endemism and high risk of degradation. Its diversity is influenced by topographical, climatic, and temperature factors, making it one of the most threatened tropical forests. In this sense, it is necessary to establish conservation strategies based on knowledge of biodiversity, strengthening Conservation Units (UCs), and valuing environmental services. One of the main groups contributing to ecosystem health is the avifauna, whose roles in seed dispersal, participation in the food chain, and importance as bioindicators are essential for a better understanding of the biome's dynamics. In this scenario, this study aimed to qualify pre-existing data on bird communities of Atlantic Forest fragments with different degrees of conservation, evaluating aspects related to distribution, feeding habits, endemism, and sensitivity to habitat degradation. From this, exploratory analyses were conducted to compare the study areas. It was observed that regions with a higher degree of degradation have avifauna with greater similarity, which was proportionally less diverse compared to more preserved areas. Through the obtained data, it will be possible to contribute to a better understanding of aspects related to environmental changes and species biodiversity, serving as a framework for the development of more efficient and targeted regeneration and conservation strategies for the Atlantic Forest.
