Florida Keys reef fish preferred different habitat corridors despite shared reef drivers
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.

Seascape models show why protecting a reef patch alone may miss life-stage movements.
