Climate change: underwater forest decline

Sala E., Kizilkaya Z., Yildirim D. & Ballesteros E. (2011) Alien marine fishes deplete algal biomass in the eastern Mediterranean. Plos One 6, e17356.

Aim: 
To determine the role of herbivorous fishes on creating a shift from macroalgal dominance to barrens in the eastern Mediterranean
Type of Study: 
Manipulative experiment
Key Results: 
A well-developed algal assemblage grew in barren habitats when fish were excluded for three months. Two tropical, invasive, herbivorous fishes (Siganus luridus and S. rivulatus) are suggested to be responsible fot the creation and maintenance of barrens
Treatments: 
Herbivore exclusion vs controls
Response: 
Targeted rabbitfish (Siganus) fishery is suggested to help restore macroalgal beds
Models: 
ANOVA
Reviewer: 
Adriana Vergés
Locations: 
SW Turkey
Response variable : 
Fish species (identity, size category, abundance), community metrics (trophic level)
Replication: 
3 replicate fish surveys per site; 12 experimental exclusion cages per site
Ecosystem: 
Temperate reef
