I did some scraping of algal mats on intertidal rocky shores. But I only managed to estimate biomass for the algae and not for the associated fauna. How useful will it be to compare the two? Are there any proxies to make the two comparable?
Specific algal diversity, diversity in the structure of algae (different size classes), and substrate type (rock smooth, crevice blocks ....) can influence the correlation between the biomass of algae and macro-benthic fauna.
