Data from: Restoring marine ecosystems: spatial reef configuration triggers taxon-specific responses among early colonizers

1. The longstanding debate in conservation biology on the importance of single large or several small (SLOSS) habitats for preserving biodiversity remains highly relevant, given the ongoing degradation and loss of natural habitats worldwide. Restoration efforts are often constrained by limited resou...

Probabilities of a positive restoration effect were high (>95%) for gadoids, labrids and demersal gobies, moderate (60-75%) for species richness and sand gobies, and low (<5%) for flatfish abundance.

The species composition at restored reefs deviated from control sites, mainly driven by large-bodied piscivores. 4. Spatial reef configuration had the strongest effect on small-bodied mesopredators, including gobies, which were more abundant and driving a distinct species assemblage at SS.
