CRED REA Algal Quadrate Images in the Pacific Ocean 2002-2008

OBIS Secretariat Open in mapper Explore occurrences

CRED is studying tropical reef algae to address the following questions: (1) What is the best way to quantify algal functional groups (macroalgae, crustose coralline algae, turf algae) in tropical reef settings? (2) What species are present in each island ecosystem and in what quantity? (3) Do changes in algal populations serve as a good environmental indicator of reef heath? (4) How do algal diversity and abundance change over time? (5) Can biogeographical hypotheses be formulated about algal dispersal and evolution using qualitative and quantitative data from island groups around the Pacific? A modified Rapid Ecological Assessment technique that incorporates the use of digital cameras and photoquadrats is our primary field method.
