Summary

AI-assisted, human-reviewed · Based on the document's abstract

Environmental DNA sampling at eight central South China Sea sites detects 190 fish species. The authors find no significant community diversity or composition differences between the two sampled depths, while modeling identifies temperature as a correlate of fish abundance.
