The reef environments in oceanic islands constitute unique ecosystems. The physical isolation of the islands, their geological characteristics and responses to sea level fluctuations resulted in the establishment of biogeographical patterns distinct from those present in coastal regions. Oceanic islands are home of organisms that have adapted to different conditions, exhibiting a high degree of speciation and endemism. Therefore, they are important sites for both ecological and evolutionary studies and for conservation actions. Despite their importance for marine biodiversity, Brazilian oceanic islands have few studies related to the natural variability of their communities, including analysis of β diversity and abundance gradients. In this context, the main objective of this project is to evaluate the variability of fish communities in Brazilian oceanic islands – Arquipélago de Trindade e Martin Vaz, Atol das Rocas, Arquipélago São Pedro e São Paulo e Arquipélago de Fernando de Noronha. For this, the project intends to combine island biogeography theory with community ecology approaches, as well as evaluating how the effects of the Anthropocene are affecting the conservation status of these ecosystems. In addition to generating scientific products, we intend to contribute with measures aiming to the effective conservation of these environments.
