To examine the importance of resource use in structuring the distribution patterns of range shifting tropical and subtropical fishes in temperate reefs within SW Japan
Type of Study:
Despite the temperate latitude surveyed (33 degrees N), the fish assemblage was dominated by tropical fishes numerically and in terms of richness within both coral, and rocky reef habitats. A relatively large number of tropical species are overwintering within both coral and rocky habitats, with a subset of these species being potentially reproductively active.
Rocky reef and coral dominated habitats
Changes in the structure and function of temperate fish communities within Japan associated with rapid shifts in climate are expected to have flow-on positive economic impacts to the local tourism industry and bring qualitative changes to local and regional fisheries resources.
