Impact of anthropogenic disturbances on the diversity of shallow stony corals in the Veracruz Reef System National Park

Resumen

Anthropogenic disturbances may affect the development and maintenance of coral reefs by promoting
diseases and other syndromes. In turn, this may cause local decreases in coral species diversity. In this study, we
compared the prevalence of syndromes (including diseases and non-disease syndromes) and the diversity of stony
coral species between reefs located close (Sacrificios reef) and far away (Santiaguillo reef) of the port of Veracruz,
Mexico. The prevalence of syndromes was higher at Sacrificios than at Santiaguillo, and it also increased with the
abundance of coral colonies at the former reef. On the other hand, coral diversity was lower at Sacrificios than at
Santiaguillo, suggesting that anthropogenic disturbances, besides promoting diseases and other syndromes, also lead to
local decreases in species diversity.
