Coral reefs rely heavily on reef fish for their health, yet overfishing has resulted in their decline, leading to an increase in fast-growing algae and changes in reef ecosystems, a phenomenon described as the phase-shift. A clearer understanding of the intricate interplay between herbivorous, their food, and their gut microbiomes could enhance reef health. This study examines the gut microbiome and isotopic markers (δC and δN) of four key nominally herbivorous reef fish species (Acanthurus chirurgus, Kyphosus sp.

- The Fundão Dam burst released a large amount of iron ore waste into the environment, prompting a study on its long-term effects, particularly on the Doce River's plume dispersion.
- Water and sediment samples were collected from three Brazilian states, revealing that the plume primarily spread north, with significant dispersal also occurring near the river's mouth.
- The study found that the organic matter and metals being transported to the ocean are largely sourced from the Doce River, emphasizing the necessity for ongoing environmental monitoring in the affected regions.
