Increased standing macroalgal biomass in upwelling zones is generally assumed to be the result of higher nutrient flux due to upwelled waters. However, other factors can strongly impact macroalgal communities. For example, herbivory and temperature, via their effects on primary producers and the metabolic demands of consumers, can also influence macroalgal biomass and productivity, respectively. Although there are a fair number of studies looking at the interactive effects of herbivores and nut...
Show moreMacroalgae accumulated in exclusion and open cages (deployed on the seafloor) was scraped and vacuumed into independent collection mesh bags after four-week trials between July 2021 and May 2022. Ash-free dry weight (AFDW) of the macroalgae samples was determined by drying each sample in an oven for 24 hours at 60° Celsius (C) and then burning it in a muffle furnace for 4 hours at 500°C.
The six field experiments were conducted in Cerro Mundo Bay, a shallow (~10 meters deep) rocky reef off the west side of San Cristobal Island, Galapagos, Ecuador (0.87044°S, 89.58189°W).
