| Outline of Final Research Achievements |
Ocean warming has led to the expansion of coral habitat and shifts in the species composition of fish assemblages on temperate rocky reefs. To clarify the mechanisms involved in these processes, the dependence of temperate and tropical fishes on different substrates (rock and coral) and the winter water temperature tolerance of tropical fishes were investigated in Kochi Prefecture, western Japan, through field observations and laboratory experiments. The results suggested that the change in substrate type from rock to coral was a major driver for the shift in species composition from temperate to tropical fish species, and that the winter water temperature tolerance of tropical fishes is a key factor that has allowed their populations to establish on temperate reefs.
