Climate change: underwater forest decline

Nakamura Y., Feary D. A., Kanda M. & Yamaoka K. (2013) Tropical fishes dominate temperate reef fish communities within western Japan. Plos One 8, e81107.

Aim: 
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: 
Survey
Key Results: 
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.
Treatments: 
Rocky reef and coral dominated habitats
Response: 
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.
Models: 
ANOVA
Reviewer: 
Adriana Vergés
Locations: 
Southwestern Japan (Tosa Bay)
Response variable : 
Fish species (identity, size category, abundance), community metrics (richness, density)
Replication: 
5 replicates, bimonthly
Ecosystem: 
Tropical-temperate transition zone
