Abstract

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 is a fair number of studies looking at the interactive effects of herbivores and nutr...

Data was collected via a data logger attached with cable ties to the seafloor. It was run to continuously record environmental temperature in the study site, Cerro Mundo.

The logger was replaced every 9 months due to battery limitations in order to keep a continuous record of temperature.
