Evidence

Peer-reviewed

Geography

Florida Keys, United States; five focal fish species and 58 management zones

System

Coral reef seascapes; fish ontogeny; nearshore-offshore connectivity

## WHAT THE EVIDENCE SAYS

A MaxEnt habitat-suitability analysis examined five habitat-shifting predatory and herbivorous reef fish and assessed 58 existing management zones in the Florida Keys. Patch and aggregate reefs were especially suitable, yet predicted spatial use differed between species and feeding guilds. The study's restoration zones scored higher in modeled suitability than protection zones, and patch reefs were relatively underrepresented.

## WHY IT MATTERS / OUR READ

Fisheries habitat decisions need life-stage and movement pathways, not merely a map of adult reef habitat. Include patch reefs, nursery connections and the distinct routes of different feeding guilds when considering restoration or area protection.

## CAVEATS / UNCERTAINTY

The findings are modeled associations and relative habitat suitability, not measured recruitment, reserve success or an experimental comparison demonstrating that restoration zones outperform protection zones.
