Implication

Research reveals community composition turnover and species richness variations in marine protected areas, indicating species protection strategies affect biodiversity.

Key Points

To examine the effects of different protection levels in marine protected areas on fish diversity and community turnover.
Conducted environmental DNA surveys across multiple zones in Chinese MMPAs
Controlled for environmental factors and human activities
Compared fish species composition and richness among fully, highly, and lightly protected zones.
High protection zones had lower fish species richness than expected
Community composition turnover between fully protected and less protected zones was 88.4%
Results suggest tiered zoning can limit biotic homogenization and sustain fish species richness.
