- The Distribution, Diversity, and Indicator Species of Coral Communities Under the Influence of Environmental Changes in the Subtropical Peninsula of Southern China.

Recently, these ecosystems have faced threats and degradation from multiple factors. In particular, coral species living at the edges of subtropical zones are important "barometers" for indicating the global boundaries of coral communities. From 2023 to 2024, we investigated the coral species composition and coverage surrounding the Dapeng Peninsula, which is located at the northern edge of the subtropical zone, and explored the influence of environmental factors on the coral community structure. Fifty-one species belonging to 20 genera and 13 families were identified in five habitats (conservation, wind-wave, tourist, fishery, and pristine areas) across three seasons. Owing to rapid urbanization and global warming, the dominant coral species shifted from branching types, which are essential reef-builders for creating structural substrates, to clumping types, which are more adaptable to environmental pressures. Notably, compared with the first report four decades ago, our current results demonstrated that coral coverage around the Dapeng Peninsula declined at an approximate rate of 0.54% per year from 1983 to 2023. Redundancy correspondence analysis revealed that substrate type, especially rock and dead coral skeletons, nitrogen and phosphorus levels, suspended particulate matter, chemical oxygen demand, and water transparency were key environmental factors that significantly (
