| Abstract |
The reef system is the main feature of the Recife de Fora Marine Park (RFMP) on the East Brazilian coast. High hydrodynamics introduce nutrients, sediment, and contaminants from rivers while promoting reef flat erosion. To identify threats to reef ecosystems, we employed a foraminifera-based assessment using the FoRAM Index and the FORAM Stress Index, combined with analyses of environmental variables. Results revealed instability/stress in part of the western backreef stations, near the Buranhém river output, and a general estuarine influence. Reef flat and backreef surroundings data are marked by health decline and instability/stress, while forereef data indicated equilibrium/stability. Active offshore processes partially compensated for coastal negative influences, helping the system to remain healthy by the active “cleansing” of waves and tides. The results established a baseline of ecosystem quality for low-cost biodiversity queries, representing an advance in assessment using foraminifera important in long-term monitoring programs. |
